Question 1

A company is migrating a legacy on-premises application to AWS. The application requires a relational database with Oracle compatibility and the ability to run read replicas across multiple Availability Zones. Which AWS service should the company use to minimize migration effort?

Accepted Answer

Amazon RDS for Oracle. Option C is correct because Amazon RDS for Oracle provides managed Oracle database with read replicas across AZs. Option A is wrong because DynamoDB is NoSQL, not relational. Option B is wrong because RDS for MySQL does not support Oracle compatibility. Option D is wrong because EC2 with self-managed Oracle requires more operational overhead.

Answer

Amazon RDS for MySQL

Answer

Amazon EC2 with self-managed Oracle

Answer

Amazon DynamoDB

Question 2

Refer to the exhibit. A company has attached this IAM policy to an IAM role used by an application running on an EC2 instance in a VPC with CIDR 10.0.0.0/16. The application is unable to read objects from the S3 bucket. What is the most likely cause?

Accepted Answer

The condition key aws:SourceIp uses the private IP of the instance, but S3 sees the public IP.. Option D is correct because the condition checks the source IP of the request, but EC2 instances use public IPs when accessing S3, so the private IP condition fails. Option A is wrong because the policy allows GetObject. Option B is wrong because S3 does not require a role for bucket access. Option C is wrong because the bucket policy is not shown.

Answer

The EC2 instance does not have an IAM instance profile.

Answer

The policy does not allow the s3:ListBucket action.

Answer

The S3 bucket policy denies access.

Question 3

A company is moving a legacy application that uses a shared file system to AWS. The application requires POSIX-compliant file storage that can be accessed by multiple EC2 instances simultaneously. Which AWS storage service should they use?

Accepted Answer

Amazon EFS. Option C (Amazon EFS) is correct because it provides a scalable, POSIX-compliant NFS file system for EC2. Option A (S3) is object storage, not POSIX. Option B (EBS) can only be attached to one instance at a time. Option D (FSx for Windows) is for SMB, not POSIX.

Answer

Amazon FSx for Windows File Server

Answer

Amazon EBS with Multi-Attach

Answer

Answer

Kerberos authentication

Answer

EBS-optimized instances

Question 5

A company is migrating a legacy on-premises application to AWS. The application uses a proprietary database that is not supported by Amazon RDS. The migration must minimize downtime and require minimal changes to the application. Which migration strategy should the company use?

Accepted Answer

Rehost the application on Amazon EC2 instances and migrate the database using AWS Database Migration Service (DMS) with ongoing replication.. Option B is correct because rehosting (lift-and-shift) involves moving the application as-is to Amazon EC2, which can host any database engine, and can minimize changes and downtime using tools like AWS Server Migration Service. Option A is incorrect because refactoring would require significant application changes. Option C is incorrect because replacing the database with a new one would require application modifications. Option D is incorrect because the database is not supported by RDS, so RDS cannot be used.

Answer

Migrate the database to Amazon RDS with a compatible engine and modify connection strings.

Answer

Refactor the application to use Amazon Aurora and modify the code to use the Aurora query interface.

Answer

Replace the database with Amazon DynamoDB and rewrite database access layer.

Question 19

Refer to the exhibit. A company is using an S3 bucket to store migration logs. The company has set a lifecycle policy to transition objects to Glacier after 30 days and expire them after 365 days. After 45 days, the company notices that the objects are still in S3 Standard. What is the most likely reason?

Accepted Answer

The objects were created after the lifecycle policy was applied, so they have not reached 30 days of age yet.. Option A is correct because lifecycle policies transition objects based on the object's age, not the creation date of the policy. The objects are less than 30 days old if they were created after the policy was applied. Option B is wrong because the policy is enabled. Option C is wrong because the filter is empty (applies to all). Option D is wrong because the policy defines a transition.

Answer

The lifecycle policy has a filter that excludes these objects.

Answer

The lifecycle policy is not enabled for the bucket.

Answer

The S3 bucket versioning is disabled, so lifecycle rules do not apply.
