A data engineer needs to securely store database credentials used by an AWS Glue ETL job. Which THREE steps should the engineer take?

Select 3 answers

A.Hardcode the credentials in the Glue job script.

B.Store the credentials in AWS Secrets Manager.

C.Grant the Glue job's IAM role permission to read the secret.

D.Configure the Glue job to use the Secrets Manager connector to retrieve credentials.

E.Use AWS Systems Manager Parameter Store with a SecureString parameter.

AnswersB, C, D

Secrets Manager provides secure storage and rotation.

Why this answer

Options A, B, and D are correct. AWS Secrets Manager securely stores credentials, and the Glue job can retrieve them via the AWS Secrets Manager connector or directly from the service. Option C is wrong because hardcoding credentials is insecure.

Option E is wrong because Parameter Store does not support automatic rotation.

MCQhard

Refer to the exhibit. A data engineer is troubleshooting a permissions issue. The IAM role 'DataEngineerRole' is used by an AWS Glue job that needs to read data from an S3 bucket encrypted with a customer managed KMS key. The above key policy is attached to the KMS key. The Glue job fails with an AccessDenied error when trying to read the data. What is the MOST likely cause?

A.The key policy requires requests to originate from a VPC endpoint, but the Glue job is not using one.

B.The key policy denies requests that are not using HTTPS, but the Glue job is using HTTPS.

C.The key policy condition 'kms:ViaService' restricts KMS actions to only when they are made through S3, but AWS Glue calls KMS directly, not via S3.

D.The Glue job is running in a different AWS region than the S3 bucket.

AnswerC

Glue does not use S3 to make KMS calls; it calls KMS directly, so the condition fails.

Why this answer

The key policy includes a condition `kms:ViaService` that restricts KMS actions to only when they are made through the S3 service. However, AWS Glue does not call KMS via S3; it calls KMS directly to decrypt the S3 object's data key. Because the Glue job's KMS request does not originate from the S3 service, the condition fails, resulting in an AccessDenied error.

Exam trap

AWS often tests the nuance that `kms:ViaService` only applies when the KMS API call is made through the specified service's endpoint, not when a service like Glue calls KMS directly to decrypt an S3 object's key.

How to eliminate wrong answers

Option A is wrong because the key policy does not contain any VPC endpoint condition; the condition shown is `kms:ViaService`, not `aws:SourceVpce`. Option B is wrong because the key policy does not include an HTTPS condition, and even if it did, AWS Glue uses HTTPS by default, so this would not cause an AccessDenied error. Option D is wrong because cross-region access to an S3 bucket is allowed as long as the KMS key is in the same region as the bucket; the error is not region-related.

MCQmedium

A company uses AWS Glue to process sensitive customer data stored in S3. The data engineer must ensure that the Glue ETL jobs do not write any data to S3 buckets that lack encryption. Which approach meets this requirement?

A.Use AWS CloudTrail to monitor and alert on unencrypted writes

B.Attach an S3 bucket policy that denies s3:PutObject unless the request includes the x-amz-server-side-encryption header

C.Enable S3 default encryption on the bucket

D.Configure an IAM role for Glue with a policy that denies s3:PutObject without encryption

AnswerB

S3 bucket policies can enforce encryption on uploads.

Why this answer

Option B is correct because an S3 bucket policy with a condition key `s3:x-amz-server-side-encryption` or `s3:x-amz-server-side-encryption-aws-kms-key-id` can deny PutObject if encryption is not specified. Option A is wrong because IAM policies cannot enforce encryption at the bucket level as effectively. Option C is wrong because CloudTrail is for auditing, not prevention.

Option D is wrong because encryption at rest does not enforce encryption on writes.

MCQmedium

A company uses AWS KMS to encrypt data in Amazon S3. The security team requires that all encryption keys be rotated automatically every year. Which key type should the company use?

A.Use a customer managed key with automatic rotation enabled

B.Use the default S3 managed encryption key (SSE-S3)

C.Use an AWS managed key (aws/s3)

D.Use a customer managed key with manual rotation

AnswerD

Customer managed keys can be rotated manually or automatically; automatic rotation can be set to yearly, so this option is correct.

Why this answer

AWS managed keys (AWS-managed KMS keys) are automatically rotated every year. Customer managed keys do not rotate automatically unless configured with a custom rotation period. The correct answer is C because AWS managed keys satisfy the requirement of automatic yearly rotation without additional configuration.

MCQhard

A data engineer notices that an S3 bucket policy allows access to a user from another AWS account, but the access is being denied. What could be the reason?

A.The bucket policy does not include KMS permissions

B.The other account's IAM user does not have permissions to access the bucket

C.S3 does not support cross-account access

D.The bucket is in a different region

AnswerB

Cross-account access requires IAM permissions in the other account.

Why this answer

For cross-account S3 access to succeed, both the bucket policy (resource-based policy) and the IAM user policy (identity-based policy) in the other account must grant the necessary permissions. Option B is correct because even if the bucket policy allows access from the other account, the IAM user in that account must have an explicit IAM policy that permits the S3 action (e.g., s3:GetObject) on the bucket. Without this, the request is denied by the other account's own IAM evaluation.

Exam trap

The trap here is that candidates assume a bucket policy alone is sufficient for cross-account access, forgetting that the requesting account's IAM user must also have explicit permissions, which is a classic AWS cross-account authorization nuance.

How to eliminate wrong answers

Option A is wrong because KMS permissions are only required if the bucket uses SSE-KMS encryption; the question does not mention encryption, and a missing KMS permission would cause a different error (e.g., AccessDenied with KMS key context). Option C is wrong because S3 fully supports cross-account access via bucket policies and ACLs, as documented in the AWS S3 User Guide. Option D is wrong because S3 is a global service and cross-region access is allowed; region does not inherently block cross-account access.

MCQhard

A company has a multi-account AWS environment with a centralized data lake in the Security account. Data producers in other accounts use AWS Glue to write data to S3 buckets in the Security account. The Security account uses AWS Lake Formation to manage permissions. The data engineer is setting up cross-account access so that users in the Producer account can query the data using Athena in their own account. The engineer has registered the S3 buckets and Data Catalog tables in Lake Formation. The IAM roles in the Producer account have the necessary permissions. However, when a user in the Producer account tries to query the table, they get an AccessDenied error. The error message indicates that the principal is not authorized to perform lakeformation:GetTable on the resource. What is the most likely cause?

A.The Glue Data Catalog resource policy is missing a statement to allow cross-account access.

B.The S3 bucket policy does not allow the Producer account's IAM role to read the data.

C.The KMS key policy does not allow the Producer account's IAM role to decrypt objects.

D.The Lake Formation permissions in the Security account do not include a grant to the Producer account's IAM role.

AnswerD

Lake Formation must grant cross-account access to the external IAM role.

Why this answer

Option A is correct because Lake Formation requires that the producer account's IAM role be granted cross-account permissions in Lake Formation. Option B is wrong because the S3 bucket policy should allow the Producer account's IAM role. Option C is wrong because the KMS key policy must allow the Producer account's IAM role.

Option D is wrong because the Glue Data Catalog policy may need cross-account access but Lake Formation is the primary issue.

A company wants to audit all data access events in their S3 buckets, including who accessed objects and from which IP address. Which AWS service should be used to capture these events?

A.AWS CloudTrail with data events enabled

B.Amazon CloudWatch Logs

C.AWS Config

D.Amazon S3 Server Access Logs

AnswerA

CloudTrail can log S3 object-level operations and capture user identity and source IP.

Why this answer

Option C is correct because AWS CloudTrail can log S3 API calls including GetObject, PutObject, etc. Option A is wrong because S3 Server Access Logs provide object-level logs but do not include IAM user details. Option B is wrong because CloudWatch Logs can store logs but not capture them directly.

Option D is wrong because Config records resource configuration changes, not data access.

MCQmedium

A data engineer needs to grant cross-account access to an S3 bucket. The engineer wants to use a role in the source account and assume that role from the target account. Which permissions are required?

A.Role in source account with trust policy allowing target account, and bucket policy granting access to the role

B.Bucket policy in source account allowing the target account's root user

C.Role in target account with trust policy allowing source account

D.IAM policy in target account allowing s3:GetObject on the bucket

AnswerA

This is the correct cross-account access pattern using role assumption.

Why this answer

The target account needs sts:AssumeRole permission on the role ARN in the source account. The source account's bucket policy must also grant access to the assumed role. Option D is correct.

A company needs to audit all API calls made in their AWS account, including actions performed by the root user. Which AWS service should be used?

A.VPC Flow Logs

B.AWS CloudTrail

C.Amazon CloudWatch Logs

D.AWS Config

AnswerB

CloudTrail records API activity for auditing.

Why this answer

Option B is correct because AWS CloudTrail records all API calls for auditing. Option A is incorrect because CloudWatch Logs stores logs but does not capture API calls natively. Option C is incorrect because AWS Config tracks resource configuration changes, not API calls.

Option D is incorrect because VPC Flow Logs capture network traffic, not API calls.

MCQhard

A company stores sensitive data in S3 and uses VPC Endpoints to restrict access. They want to ensure that data can only be accessed from their VPC. What configuration is required?

A.Configure VPC Flow Logs to monitor access

B.Add a bucket policy condition aws:SourceVpce

C.Enable S3 Block Public Access

D.Associate a security group with the S3 bucket

AnswerB

This condition restricts access to requests originating from the specified VPC endpoint.

Why this answer

S3 bucket policies can use aws:SourceVpce condition to restrict access to a specific VPC endpoint. Option A is wrong because S3 Block Public Access is a broader setting. Option B is wrong because VPC Flow Logs log traffic but do not restrict access.

Option D is wrong because security groups apply to EC2 instances, not to S3 bucket policies directly.

A company uses AWS KMS to encrypt data in multiple services. They want to ensure that only specific IAM roles can decrypt data using a particular KMS key. Which THREE steps are necessary?

Select 3 answers

A.Attach an IAM policy to each role with kms:Decrypt permission

B.Enable IAM policies in the key policy

C.Enable automatic key rotation

D.Ensure the key policy allows kms:GenerateDataKey for the roles

E.Add a statement to the KMS key policy allowing kms:Decrypt for the IAM roles

AnswersA, D, E

The roles need an IAM policy that allows decrypt actions.

Why this answer

The KMS key policy must grant decrypt permission to the IAM roles. Each role must have an IAM policy allowing kms:Decrypt. Additionally, the key policy should also grant kms:GenerateDataKey for encryption.

Option D is wrong because the key policy does not need to enable IAM policies; by default, IAM policies are allowed unless the key policy denies them. Option E is wrong because key rotation is not required for access control.

MCQmedium

A data engineer is troubleshooting an issue where an AWS Glue ETL job fails when trying to read data from an S3 bucket encrypted with SSE-KMS. The job has an IAM role that includes `kms:Decrypt` permission. What is the most likely reason for the failure?

A.The IAM role does not have s3:GetObject permission

B.The KMS key policy does not allow the Glue job to use the key

C.The S3 bucket is in a different AWS region than the Glue job

D.The Glue job is not configured to use the KMS key for decryption

AnswerD

Glue needs the key ID or alias in the job parameters.

Why this answer

Option B is correct because Glue needs the KMS key to be specified in the job parameters or the connection. Option A is wrong because the Glue role likely has the permission. Option C is wrong because the bucket may be in the same region.

Option D is wrong because the key must be specified explicitly.

MCQeasy

A company wants to use AWS Lake Formation to manage permissions on a data lake. What is the primary benefit of using Lake Formation for data security?

A.Automatically encrypts data at rest and in transit.

B.Replaces IAM for all data access policies.

C.Provides a unified view of data across all AWS regions.

D.Centralized fine-grained access control to data in S3, Redshift, and RDS.

AnswerD

Lake Formation provides column and row-level security.

Why this answer

Option A is correct because Lake Formation provides centralized fine-grained access control at the table, column, and row level. Option B is wrong because Lake Formation does not replace IAM. Option C is wrong because it does not encrypt data.

Option D is wrong because Lake Formation works with S3, not just Redshift.

A company is using AWS Glue to process data stored in an S3 bucket that is encrypted with SSE-KMS. The Glue job fails with an 'Access Denied' error when trying to read the data. The IAM role used by the Glue job has permissions to read from the S3 bucket and to use the KMS key. What is the most likely cause of the failure?

A.The S3 bucket is using SSE-S3 instead of SSE-KMS

B.The S3 bucket policy denies access to the Glue job

C.The KMS key is in a different AWS account

D.The IAM role is missing the kms:Decrypt permission

AnswerD

Glue jobs need kms:Decrypt to read SSE-KMS encrypted data.

Why this answer

Option D is correct because AWS Glue jobs need the kms:Decrypt permission on the KMS key to read data encrypted with SSE-KMS. The IAM role may have the S3 read permissions but lack the kms:Decrypt permission. Option A (SSE-S3) is not relevant as the bucket uses SSE-KMS.

Option B (bucket policy) could also be a cause, but the most common issue is missing kms:Decrypt. Option C (cross-account access) is less likely if the key is in the same account.

A data engineer needs to ensure that an Amazon Redshift cluster encrypts all data at rest. Which setting must be enabled when creating the cluster?

A.Enable automated snapshots

B.Enable encryption

C.Enable SSL/TLS

D.Enable VPC

AnswerB

Redshift supports encryption at rest.

Why this answer

Option B is correct. Redshift cluster encryption is enabled at creation. Option A is wrong because SSL is for in-transit.

Option C is wrong because VPC is network isolation. Option D is wrong because automated snapshots are for backup.

MCQhard

A data engineer is troubleshooting an Amazon Redshift cluster that is not allowing connections from a specific IP range. The engineer verified that the cluster's security group allows inbound traffic from the IP range. What is the next step to resolve the issue?

A.Modify the Redshift cluster parameter group to enable public accessibility.

B.Verify that the cluster's security group is attached to the Redshift cluster.

C.Check the IAM role associated with the Redshift cluster.

D.Check the network ACL (NACL) associated with the Redshift cluster's subnet.

AnswerD

NACLs can block traffic at the subnet level even if security groups allow it.

Why this answer

Option C is correct because Redshift also uses a VPC network ACL (NACL) that can block traffic at the subnet level, independent of security groups. Option A is wrong because the security group already allows traffic. Option B is wrong because IAM roles do not control network-level access.

Option D is wrong because the cluster parameter group does not control network access.

A company uses Amazon Redshift to store customer data. The security team requires that all queries are logged for auditing purposes. Which combination of steps should be taken to meet this requirement? (Select TWO.)

Select 2 answers

A.Enable AWS CloudTrail database audit logging.

B.Use AWS CloudTrail to log Redshift API calls.

C.Enable logging on the Redshift security group.

D.Enable VPC Flow Logs for the Redshift cluster.

E.Enable Amazon Redshift audit logging to an S3 bucket.

AnswersB, E

CloudTrail logs API calls, including query execution.

Why this answer

Option B is correct because AWS CloudTrail can be configured to log Redshift API calls, such as CreateCluster, DeleteCluster, and ModifyCluster, which provides an audit trail of administrative actions. Option E is correct because Amazon Redshift supports native audit logging, including connection logs, user activity logs, and query logs, which can be exported to an Amazon S3 bucket for long-term retention and analysis.

Exam trap

The trap here is that candidates confuse AWS CloudTrail's ability to log API calls with database-level query logging, leading them to incorrectly select CloudTrail as the sole solution, while overlooking the need for Redshift's native audit logging to capture actual SQL queries.

A company is designing a data lake on Amazon S3. The security policy requires that all data be encrypted at rest using AWS KMS with automatic key rotation. Which encryption option meets these requirements? (Select THREE.)

Select 3 answers

A.Enable automatic key rotation on the KMS key.

B.Use SSE-KMS with an AWS managed key.

C.Set the default encryption on the S3 bucket to SSE-KMS with the CMK.

D.Use SSE-KMS with a customer-managed key (CMK).

E.Use SSE-C with a customer-provided key.

AnswersA, C, D

This is a requirement.

Why this answer

Option A is correct because AWS KMS customer-managed keys (CMKs) support automatic key rotation, which can be enabled to rotate the key material annually. This satisfies the security policy requirement for automatic key rotation. SSE-KMS with a CMK (Option D) is also required because AWS managed keys (Option B) do not support automatic key rotation, and SSE-C (Option E) does not use KMS at all.

Setting default encryption on the S3 bucket to SSE-KMS with the CMK (Option C) ensures all objects are encrypted with that key, meeting the encryption-at-rest requirement.

Exam trap

The trap here is that candidates often assume AWS managed keys (aws/s3) support automatic key rotation, but they do not; only customer-managed CMKs allow you to enable automatic rotation, and the question requires selecting three correct options that together meet both the KMS and automatic rotation requirements.

A company uses AWS KMS to encrypt sensitive data in S3. The security team requires that the KMS key must be rotated automatically every year. Which key type should be used?

A.Asymmetric customer managed key

B.AWS managed key (aws/s3)

C.Custom key store backed by CloudHSM

D.Customer managed key with automatic rotation enabled

AnswerB

AWS managed keys automatically rotate every year, meeting the requirement.

Why this answer

Option A is correct because AWS managed keys (with automatic rotation) rotate annually by default. Option B is wrong because customer managed keys (with rotation enabled) rotate annually, but the key material is not rotated automatically unless imported key material is used. Option C is wrong because AWS managed keys rotate automatically, but custom key stores are for CloudHSM.

Option D is wrong because asymmetric keys are not automatically rotated.

A data engineer is designing a data lake on S3 and needs to ensure that data is encrypted at rest using customer-managed KMS keys. The engineer also needs to audit all access to the KMS keys. Which combination of services should be used?

A.SSE-KMS with AWS CloudTrail

B.SSE-C with CloudWatch Logs

C.SSE-KMS with S3 Inventory

D.SSE-S3 with S3 server access logs

AnswerA

SSE-KMS uses customer-managed KMS keys; CloudTrail records KMS API calls for auditing.

Why this answer

S3 server-side encryption with KMS (SSE-KMS) uses customer-managed KMS keys. CloudTrail logs all KMS API calls, including Decrypt and GenerateDataKey. Option A is wrong because SSE-S3 uses AWS-managed keys, not customer-managed.

Option B is wrong because S3 Inventory does not audit KMS access. Option D is wrong because S3 access logs do not capture KMS operations. Option C is correct.

A.BlockPublicAcls (both new and existing)

B.IgnorePublicAcls

C.BlockPublicAcls (new ACLs)

D.BlockPublicPolicy

AnswerA

Blocks all public ACLs.

Why this answer

Option B is correct because BlockPublicAcls prevents public ACLs on the bucket. Option A is wrong because it only applies to new ACLs. Option C is wrong because it blocks public bucket policies.

Refer to the exhibit. A data engineer has attached this KMS key policy to a customer-managed key. The policy is intended to allow the DataEngineer role to decrypt objects in S3 only when the request comes through S3. However, the role is unable to decrypt objects stored in an S3 bucket in the us-west-2 region. What is the most likely cause?

A.The key policy does not allow the role to use GenerateDataKey

B.The role does not have an IAM policy that allows kms:Decrypt

C.The condition restricts the permission to the us-east-1 region only

D.The role does not have permission to decrypt from S3

AnswerC

The kms:ViaService condition specifies s3.us-east-1.amazonaws.com, so it only works for S3 requests in us-east-1.

Why this answer

The condition in the policy restricts the permission to requests coming through S3 in us-east-1 only (s3.us-east-1.amazonaws.com). For buckets in us-west-2, the viaService would be s3.us-west-2.amazonaws.com, so the condition fails. The key policy does not allow decrypt from other services, but the issue is region mismatch.

A data engineering team uses AWS Lambda functions to process streaming data from Amazon Kinesis Data Streams and write the results to an S3 bucket. The S3 bucket is encrypted with SSE-KMS using a customer-managed key (CMK). The Lambda function's IAM role has permissions for kms:Decrypt and kms:GenerateDataKey on the CMK. However, the Lambda function fails with an 'Access Denied' error when writing to S3. The S3 bucket policy allows s3:PutObject from the Lambda function's IAM role. What is the most likely cause?

A.The Lambda function's execution role does not have permission to invoke the function.

B.The Lambda function's IAM role is missing the kms:Encrypt permission on the CMK.

C.The S3 bucket policy denies s3:PutObject from the Lambda function.

D.The Kinesis data stream is not encrypted, causing the Lambda function to fail.

AnswerB

Writing encrypted data requires kms:Encrypt.

Why this answer

Option A is correct. When writing to S3 with SSE-KMS, the Lambda function needs kms:Encrypt permission to encrypt the data. The role only has kms:Decrypt and kms:GenerateDataKey, missing kms:Encrypt.

Option B is wrong because Kinesis encryption is separate. Option C is wrong because the bucket policy allows PutObject. Option D is wrong because Lambda has permissions, but missing kms:Encrypt.

D.Update the S3 bucket policy to allow Account B's root user

AnswerC

Both are required for decryption and access.

Why this answer

To share S3 objects encrypted with a KMS key, you must grant the consuming account access to both the S3 bucket and the KMS key. Option A is wrong because a bucket policy alone does not grant KMS permissions. Option B is wrong because the KMS key policy must explicitly allow Account B.

Option C is correct as it includes both. Option D is wrong because cross-account roles are not necessary if bucket policy and key policy are used.

A company is using Amazon Redshift for analytics and needs to ensure that all data is encrypted at rest. The current cluster does not have encryption enabled. What is the most efficient way to enable encryption?

A.Change the cluster parameter group to enable encryption

B.Modify the cluster configuration to enable encryption

C.Use AWS DMS to migrate data to a new encrypted cluster

D.Create a snapshot of the cluster and restore it to a new cluster with encryption enabled

AnswerD

This is the supported method to migrate to an encrypted cluster.

Why this answer

Redshift does not support enabling encryption on an existing cluster; a new encrypted cluster must be created and data migrated. Modifying the cluster configuration or parameter groups does not enable encryption. Creating a snapshot and restoring it to a new cluster with encryption enabled is the standard approach.

D.AWS Secrets Manager

AnswerD

Secrets Manager provides automatic rotation of secrets.

Why this answer

Option D is correct because AWS Secrets Manager supports automatic rotation of secrets. Option A is wrong because Parameter Store does not natively rotate secrets. Option B is wrong because CloudHSM is a hardware security module, not a secret store with rotation.

A company is using AWS Glue to process data stored in Amazon S3. The data includes personally identifiable information (PII) that must be masked before being written to a separate output bucket. Which AWS service or feature can be used to automatically detect and mask sensitive data in the Glue ETL job?

A.Configure CloudWatch Logs to filter and mask PII.

B.Use Amazon Macie to identify sensitive data and apply masking logic in the Glue job.

C.Use an IAM policy to restrict access to the PII columns.

D.Enable S3 Object Lock on the output bucket.

AnswerB

Amazon Macie can detect sensitive data, and the Glue job can use that information to mask it.

Why this answer

Option D is correct because Amazon Macie can be integrated with AWS Glue to detect and mask sensitive data. Option A is wrong because IAM policies control access, not data masking. Option B is wrong because S3 Object Lock prevents object deletion or modification, not masking.

Refer to the exhibit. A data engineer applies this S3 bucket policy to the bucket 'example-bucket'. What is the effect of this policy?

A.PutObject requests are denied unless they include the x-amz-server-side-encryption header set to AES256

B.All PutObject requests are denied regardless of encryption

C.All PutObject requests are allowed only if they use SSE-KMS

D.The policy has no effect because it does not allow any action

AnswerA

The condition StringNotEquals denies if the header is not AES256, so only requests with AES256 are allowed.

Why this answer

The policy denies s3:PutObject if the encryption header is not set to AES256 (SSE-S3). It does not enforce a specific KMS key. It allows uploads with SSE-S3.

It denies uploads without encryption or with other encryption types.

The security policy mandates that all data in transit between AWS Glue and Redshift must be encrypted using TLS. The team uses a JDBC connection. Currently, the connection is failing with an SSL-related error. Which configuration change should the team make to ensure encrypted connectivity?

A.Modify the Redshift security group to allow inbound traffic on port 5439 from the Glue subnet.

B.Update the JDBC connection string to include ssl=true and sslmode=require.

C.Enable server-side encryption on the S3 bucket using AWS KMS.

D.Set the Redshift cluster parameter group to require_ssl=ON.

AnswerB

Ensures the JDBC driver uses SSL encryption.

Why this answer

To enforce SSL for JDBC connections to Redshift, you must add the ssl=true parameter in the connection URL. Option D is correct. Option A is wrong because the security group controls network access, not encryption.

Option B is wrong because enabling encryption on the S3 bucket does not affect the Glue-to-Redshift connection. Option C is wrong because Redshift uses SSL by default, but the JDBC driver requires explicit ssl=true in the URL to enable it.

D.Add an IAM policy to the role that requires MFA for kms:Decrypt

E.Configure the S3 bucket to use SSE-KMS with the customer-managed key

AnswersC, E

This restricts decryption to the specified roles.

Why this answer

To restrict decryption to specific roles, you need to create a customer-managed key, configure the key policy to allow only those roles to use kms:Decrypt, and use SSE-KMS when writing objects. Using the default KMS key does not allow custom policies. SSE-S3 uses different keys.

Requiring MFA for API calls does not restrict decryption to specific roles.

A data engineer is troubleshooting an AWS Glue ETL job that fails with an access denied error when writing to an S3 bucket. The Glue job uses an IAM role that has an S3 bucket policy attached. The bucket policy denies access to any principal that does not use server-side encryption. What is the most likely cause of the failure?

A.The VPC endpoint policy for S3 is too restrictive.

B.The IAM role does not have s3:PutObject permission.

C.The Glue job is not using server-side encryption when writing to S3.

D.The S3 bucket uses S3 Block Public Access which denies all writes.

AnswerC

The bucket policy denies requests without encryption, causing access denied even if the role has PutObject permission.

Why this answer

Option C is correct because if the Glue job does not set the encryption header (or the role does not have the kms:GenerateDataKey permission for SSE-KMS), the bucket policy will deny the request. Option A is wrong because Glue requires permissions on the S3 bucket and KMS key. Option B is wrong because VPC endpoints do not cause access denied errors for encryption.

A company is using an Amazon RDS for PostgreSQL database to store personally identifiable information (PII). The security team wants to ensure that database administrators cannot view the plaintext PII data. Which solution should a data engineer implement?

A.Use IAM policies to restrict DBA access to the RDS instance

B.Enable Dynamic Data Masking in RDS to obfuscate PII for all users

C.Enable encryption at rest for the RDS instance using AWS KMS

D.Use client-side encryption with AWS KMS to encrypt PII before inserting into the database

AnswerD

Client-side encryption ensures data is encrypted before reaching the database, so DBAs cannot see the plaintext.

Why this answer

Using AWS KMS with client-side encryption ensures that data is encrypted before being sent to RDS, so database administrators cannot read the plaintext. Dynamic data masking in RDS is not natively supported; application-level masking would be needed. RDS encryption at rest protects data on disk but DBAs with access can still query plaintext.

Using IAM policies to restrict access does not prevent DBAs with database credentials from viewing data.

A company uses AWS Lake Formation to manage data lake permissions. The data lake contains sensitive customer data in the 'customer' database. The security team wants to ensure that only users with a specific tag 'access_level=analyst' can query the 'customer' table. Which combination of steps should the data engineer take to enforce this?

A.In Lake Formation, create an LF-tag 'access_level' with values 'analyst' and 'admin'. Grant 'SELECT' permission on the 'customer' table to the tag value 'analyst'. Associate the LF-tag with the 'customer' table.

B.Create an IAM policy that conditionally allows 'glue:GetTable' based on the tag 'access_level=analyst'.

C.Apply a bucket policy on the S3 location of the 'customer' table that allows access only if the request carries the tag 'access_level=analyst'.

D.Use Lake Formation column-level filters to restrict access to columns based on the tag 'access_level=analyst'.

AnswerA

This uses Lake Formation TBAC to restrict access based on the user's tag.

Why this answer

Option A is correct because Lake Formation LF-tags allow you to define metadata tags (key-value pairs) and grant permissions to those tags. By creating an LF-tag 'access_level' with values 'analyst' and 'admin', granting SELECT on the 'customer' table to the tag value 'analyst', and associating that LF-tag with the table, only principals who have the tag 'access_level=analyst' (or are granted via the tag) can query the table. This enforces tag-based access control at the Lake Formation permission layer, which is the intended mechanism for fine-grained, attribute-based access control in Lake Formation.

Exam trap

The trap here is that candidates often confuse IAM tag-based policies (Option B) or S3 bucket policies (Option C) with Lake Formation's native LF-tag mechanism, not realizing that LF-tags are a Lake Formation-specific construct that must be managed within Lake Formation itself, not at the IAM or S3 level.

How to eliminate wrong answers

Option B is wrong because an IAM policy conditionally allowing 'glue:GetTable' based on a tag controls access to the Glue Data Catalog API, but it does not enforce Lake Formation permissions on the underlying data; Lake Formation permissions override IAM policies for registered locations, and this approach would not prevent a user with the tag from querying the table if Lake Formation grants are not also configured. Option C is wrong because S3 bucket policies operate at the object storage layer and cannot evaluate Lake Formation LF-tags; they can use IAM tags via the 'aws:RequestTag' condition key, but this would require the request to carry the tag, which is not how Lake Formation principals are identified, and it would bypass Lake Formation's centralized permission model. Option D is wrong because column-level filters in Lake Formation restrict access to specific columns based on a filter expression, not based on LF-tags; LF-tags are used for row-level or table-level permission grants, not for column-level filtering.

A company stores sensitive customer data in an Amazon S3 bucket with versioning enabled. A data engineer accidentally deleted the current version of an object. What is the quickest way to restore the object to its previous state without additional data transfer costs?

A.Use S3 Batch Operations to restore the object from the Recycle Bin.

B.Delete the delete marker that was created by the deletion.

C.Copy the previous version from the bucket to itself.

D.Use the S3 sync command to restore the previous version.

AnswerB

Deleting the delete marker restores the previous version as the current object without copying data.

Why this answer

With versioning enabled, deleted objects become delete markers. To restore, you delete the delete marker, which makes the previous version current again. Option A is correct.

Option B costs data transfer. Option C restores to a different bucket. Option D is not a valid operation.

A company uses AWS Glue to process sensitive data stored in Amazon S3. The security team requires that all data in transit between AWS Glue and S3 be encrypted. Which configuration should be used to meet this requirement?

A.Use an S3 bucket policy that denies requests not using HTTPS.

B.Use an AWS KMS key to encrypt the data before uploading to S3.

C.Configure AWS Glue to use SSL by setting the 'ssl' parameter to 'true'.

D.Enable default encryption on the S3 bucket using SSE-S3.

AnswerA

This enforces encryption in transit for all requests.

Why this answer

Option A is correct because requiring HTTPS for all requests to the S3 bucket ensures that data in transit between AWS Glue and S3 is encrypted using TLS. By using an S3 bucket policy with a condition that denies requests where `aws:SecureTransport` is false, the company enforces encryption for all connections, including those from AWS Glue. This meets the security requirement without needing to modify Glue or S3 configurations beyond the bucket policy.

Exam trap

The trap here is that candidates often confuse encryption at rest (SSE-S3, SSE-KMS, client-side encryption) with encryption in transit (TLS/HTTPS), and may incorrectly assume that enabling default encryption or using KMS keys secures the data during transfer.

How to eliminate wrong answers

Option B is wrong because encrypting data with an AWS KMS key before uploading to S3 (client-side encryption) protects data at rest, not data in transit; the security team specifically requires encryption in transit. Option C is wrong because AWS Glue does not have an 'ssl' parameter; Glue uses HTTPS by default when connecting to S3, and this setting is not configurable via a simple parameter. Option D is wrong because enabling default encryption on the S3 bucket (SSE-S3) only encrypts data at rest, not data in transit between Glue and S3.

An organization needs to audit all access to their S3 buckets for compliance purposes. They want to log both successful and failed API calls. Which AWS service should be used?

A.Amazon CloudWatch Logs

B.AWS Config

C.AWS CloudTrail

D.VPC Flow Logs

AnswerC

CloudTrail logs API calls for auditing.

Why this answer

Option C is correct because AWS CloudTrail logs API activity in an AWS account, including S3 operations. Option A (Amazon CloudWatch) monitors metrics, not API calls. Option B (AWS Config) tracks resource configuration changes, not API calls.

Option D (VPC Flow Logs) captures network traffic, not API calls.

A company uses Amazon RDS for MySQL to store application data. The database contains personally identifiable information (PII). The security team requires that all data be encrypted at rest using AWS KMS. The database is currently unencrypted. The data engineer needs to enable encryption without significant downtime. Which approach should the data engineer take?

A.Use AWS DMS to migrate data to a new encrypted RDS instance continuously.

B.Take a snapshot of the database, copy it with encryption enabled, and restore from the encrypted snapshot.

C.Create a read replica with encryption enabled and promote it to primary.

D.Modify the RDS instance and enable encryption in the configuration.

AnswerB

Standard procedure to enable encryption on existing RDS.

Why this answer

Option D is correct. To enable encryption on an existing RDS instance, you must take a snapshot, copy it with encryption, and restore from the encrypted snapshot. This process involves some downtime but is the only way.

Option A is wrong because you cannot modify the instance to enable encryption directly. Option B is wrong because you cannot enable encryption on the existing instance via modification. Option C is wrong because DMS requires source and target, and the target can be encrypted, but it's more complex.

A company uses AWS Lake Formation to manage permissions on a data lake stored in S3. A data scientist is unable to query a table in Amazon Athena, receiving an 'Access Denied' error. The data scientist has IAM permissions to call Athena and has been granted SELECT permission on the table in Lake Formation. What is the most likely cause?

A.The data scientist does not have DESCRIBE permission on the table.

B.The data is encrypted with SSE-KMS and the data scientist lacks kms:Decrypt permission.

C.The S3 bucket policy denies access to the data scientist's IAM role.

D.The S3 bucket containing the data is not registered as a Lake Formation location.

AnswerD

Prevents Lake Formation from granting S3 access.

Why this answer

Lake Formation requires explicit S3 permission via a resource link or register location. Option B is correct because if the underlying S3 location is not registered or the IAM role does not have S3 access, the query fails. Option A is wrong because the data scientist has SELECT permission.

Option C is wrong because encryption is not the issue. Option D is wrong because Lake Formation bypasses S3 bucket policies for registered locations.

A data engineer needs to ensure that an S3 bucket can only be accessed from a specific VPC. Which policy element should be used?

A.Use the condition key aws:VpcSourceIp in the bucket policy.

B.Use the condition key aws:SourceIp in the bucket policy.

C.Use the condition key aws:SourceVpce in the bucket policy.

D.Use the condition key aws:SourceVpc in the bucket policy.

AnswerD

This restricts access to requests from the specified VPC.

Why this answer

Option B is correct because the condition key aws:SourceVpc restricts requests to originate from a specific VPC. Option A limits to a VPC endpoint, not the VPC itself. Option C is for specific IPs.

Option D is for VPC endpoint IDs.

A data engineer needs to grant an IAM role read-only access to Amazon DynamoDB tables in a specific AWS account. Which IAM policy element should be used to restrict access to only the 'GetItem' and 'Query' actions?

A.Resource

B.Action

C.Effect

D.Condition

AnswerB

Action specifies the API actions like GetItem and Query.

Why this answer

The 'Action' element specifies the allowed API actions. 'Effect' is 'Allow' or 'Deny'. 'Resource' specifies the ARN. 'Condition' adds conditions. So Action is correct.
