CCSP Timed Hard Questions — 25 Difficult Questions

Question 1

A cloud provider experiences a data breach affecting customer data. Which of the following laws most likely requires the provider to notify affected customers within 72 hours?

Accepted Answer

GDPR. The GDPR (General Data Protection Regulation) explicitly requires data controllers to notify the relevant supervisory authority of a personal data breach within 72 hours of becoming aware of it, and to communicate the breach to affected data subjects without undue delay if it poses a high risk to their rights and freedoms. This 72-hour notification mandate is unique to GDPR among the listed options, making it the correct answer for a cloud provider experiencing a data breach affecting customer data.

Answer

SOX

Answer

HIPAA

Answer

PCI DSS

Question 2

Refer to the exhibit. A security analyst reviews the S3 bucket policy shown. Which security issue should be flagged?

Accepted Answer

The policy allows unauthenticated write access to the bucket. Option C is correct because the S3 bucket policy contains a Principal element set to "*" with an Effect of "Allow" on the s3:PutObject action, which grants unauthenticated write access to the bucket. This means anyone on the internet can upload objects without any authentication, leading to potential data corruption, storage cost abuse, or malware hosting. The policy does not include any condition (e.g., aws:SourceIp or aws:SecureTransport) to restrict the write operation, making it a critical security misconfiguration.

Answer

The policy restricts read access to a specific role, which is too permissive

Answer

The policy does not enable server-side encryption

Answer

The policy contains a syntax error in the JSON

Question 3

Refer to the exhibit. A security engineer discovers that the S3 bucket policy allows public read access from the entire corporate network (10.0.0.0/16). However, the company wants to restrict access only to the security team's subnet (10.0.1.0/24). What modification should be made to the policy?

Accepted Answer

Change the Condition value to "aws:SourceIp": "10.0.1.0/24".. Option D is correct because modifying the Condition value to "aws:SourceIp": "10.0.1.0/24" directly restricts the S3 bucket policy to allow read access only from the security team's subnet. The original policy uses the aws:SourceIp condition key with the broader 10.0.0.0/16 range, so narrowing it to 10.0.1.0/24 precisely enforces the required access control. This approach leverages AWS IAM policy evaluation logic where an explicit Allow with a condition must be satisfied for access to be granted.

Answer

Add a Deny statement for the 10.0.0.0/16 range.

Answer

Add a Deny statement for IP addresses outside 10.0.1.0/24.

Answer

Remove the Condition element to allow access from any IP.

Question 4

Which TWO of the following are required elements of a valid Business Continuity Plan (BCP) in the cloud?

Accepted Answer

Communication plan for notifying stakeholders during a disruption.. Option A is correct because a communication plan is a mandatory component of any BCP, as defined by ISO 22301 and NIST SP 800-34. In a cloud context, this plan must specify how to notify stakeholders—including the CSP, internal teams, and customers—during a disruption, ensuring coordinated response and compliance with SLAs.

Answer

Strategy to avoid vendor lock-in with the CSP.

Answer

A detailed risk assessment for all cloud services.

Answer

Network topology diagrams of the cloud environment.

Question 5

A cloud security engineer reviews the S3 bucket policy shown in the exhibit. What is the net effect of this policy when a request originates from IP address 203.0.113.10 over HTTPS?

Accepted Answer

Deny access because the request is from the specified IP range. The S3 bucket policy includes a Deny statement that blocks all requests from the IP range 203.0.113.0/24, which includes 203.0.113.10. The SecureTransport condition is only applied to the Allow statement, not the Deny, so HTTPS is irrelevant to the Deny effect. Since the request matches the IP address in the Deny statement, it is denied regardless of protocol.

Answer

Deny access because the request does not meet the SecureTransport condition

Answer

Allow access because the condition for Deny does not include SecureTransport

Answer

Allow access because the request uses HTTPS

Question 6

A company is migrating a critical application to the cloud and must ensure that its security operations center (SOC) can detect and respond to threats in real time. The application generates high volumes of logs. Which combination of services would provide the MOST efficient and cost-effective solution for centralized logging, analysis, and alerting?

Accepted Answer

Implement a Security Information and Event Management (SIEM) system with real-time correlation and a log management solution that auto-scales.. Option B is correct because a SIEM system with real-time correlation enables the SOC to detect threats as they occur by analyzing log data across multiple sources, while an auto-scaling log management solution ensures cost efficiency by dynamically adjusting resources to handle high log volumes without over-provisioning. This combination provides centralized logging, real-time analysis, and alerting, meeting the requirement for efficient and cost-effective threat detection.

Answer

Deploy a basic monitoring tool that triggers alerts based on static thresholds.

Answer

Use a cloud-native log storage service with long retention and no analysis.

Answer

Store logs in a centralized log server and have SOC analysts manually review them.

Question 7

Which TWO of the following are primary responsibilities of a cloud service customer under the shared responsibility model regarding compliance with regulations such as GDPR?

Accepted Answer

Implementing data encryption for sensitive data at rest. The customer is responsible for data encryption and access controls (B and E). Physical security and penetration testing are provider responsibilities. Verifying certifications is a customer due diligence task but not a primary responsibility compared to direct data protection measures.

Answer

Conducting annual penetration tests on the provider's infrastructure

Answer

Ensuring the cloud provider's physical security controls are adequate

Answer

Verifying the provider's compliance certifications are current

Question 8

A cloud security architect is designing a secure CI/CD pipeline for a containerized application deployed on a Kubernetes cluster. The pipeline must ensure that only approved images are deployed. Which TWO of the following controls should be implemented? (Choose two.)

Accepted Answer

Configure the Kubernetes admission controller to reject pods that use unsigned images.. Option B is correct because Kubernetes admission controllers can enforce policies such as rejecting pods that use unsigned images, ensuring only images with verified signatures are deployed. This directly addresses the requirement to deploy only approved images by validating image integrity at admission time.

Answer

Implement role-based access control (RBAC) to restrict who can push images to the registry.

Answer

Use network policies to restrict pod-to-pod communication.

Answer

Scan all container images for vulnerabilities in the CI pipeline.

Question 9

An administrator applies the above S3 bucket policy to a bucket named 'data-bucket' that contains sensitive logs. The policy is intended to allow uploads only over HTTPS. After applying, the administrator finds that uploads using the AWS CLI without HTTPS still succeed. What is the most likely reason?

Accepted Answer

The bucket's ACLs grant PutObject permission to the authenticated user, which takes effect before the bucket policy is evaluated.. Option C is correct because S3 bucket policies and ACLs are evaluated independently, and if an ACL grants PutObject permission to the authenticated user, that permission is effective even if a bucket policy denies the same action based on a condition like 'aws:SecureTransport'. The AWS CLI request without HTTPS still succeeds because the ACL allows the upload before the bucket policy's Deny statement is evaluated, as S3 evaluates all access control mechanisms and grants access if any applicable policy allows it, unless an explicit Deny is present in the same policy evaluation context. However, the bucket policy's Deny statement does not override the ACL's Allow because the ACL is a separate authorization mechanism that is evaluated first, and S3's authorization model grants access if any of the policies (ACL, bucket policy, user policy) allow the action, provided there is no explicit Deny from the same source.

Answer

The 'aws:SecureTransport' condition key is not supported for S3 bucket policies.

Answer

The policy does not apply to requests made by the AWS root account user.

Answer

The bucket policy has a syntax error; the Allow and Deny statements cannot be combined in the same policy.

Question 10

Refer to the exhibit. A cloud security analyst is reviewing an S3 bucket policy. The bucket contains sensitive data and must only be accessible over HTTPS from the internal network (10.0.0.0/24). Which of the following correctly describes the behavior of this policy?

Accepted Answer

Requests from 10.0.0.0/24 over HTTPS are allowed; all other requests are denied.. The policy uses an explicit Deny for any request that is not using HTTPS (i.e., aws:SecureTransport is false) or does not originate from the 10.0.0.0/24 IP range. This Deny overrides the Allow statement, ensuring that only requests meeting both conditions (source IP 10.0.0.0/24 AND HTTPS) are permitted. Requests from 10.0.0.0/24 over HTTPS satisfy the Allow and are not caught by the Deny, so they are allowed; all other requests are denied.

Answer

Requests from 10.0.0.0/24 over HTTP are allowed because the Allow statement matches.

Answer

The policy is invalid because it combines Allow and Deny statements.

Answer

All requests from 10.0.0.0/24 are denied because the Deny statement applies to all actions.

Question 11

An AWS S3 bucket policy is configured as shown in the exhibit. The security team wants to ensure that only requests from the corporate IP range (203.0.113.0/24) can read objects in the bucket. However, they notice that a CloudFront distribution configured to serve content from this bucket is returning 403 Forbidden errors. What is the MOST likely cause?

Accepted Answer

CloudFront requests originate from CloudFront IP addresses, not the end user's IP.. D is correct because when CloudFront fetches objects from an S3 origin, it uses its own IP addresses, not the end user's IP address. The bucket policy restricts access to the corporate IP range (203.0.113.0/24), but CloudFront's requests come from AWS's CloudFront edge IP range, which falls outside that range. This causes S3 to deny the request, resulting in a 403 Forbidden error.

Answer

The bucket policy has a syntax error in the Condition block.

Answer

There is an implicit deny that overrides the explicit allow.

Answer

The bucket policy does not allow the s3:GetObject action.

Question 12

Refer to the exhibit. A cloud security analyst reviews the bucket policy for example-bucket. Based on the policy, which of the following is true?

Accepted Answer

Requests from IP 192.0.2.10 over HTTPS are allowed.. Option A is correct because the bucket policy includes an explicit Allow statement granting s3:GetObject to all principals (Principal: "*") from the IP address 192.0.2.10, and the condition "Bool": {"aws:SecureTransport": "true"} ensures that only HTTPS requests are allowed. Since the request originates from the specified IP and uses HTTPS, it satisfies both the Allow condition and is not blocked by the Deny statement, which only denies requests when SecureTransport is false (i.e., HTTP). Thus, the request is permitted.

Answer

Access is denied because the Principal is set to "*", which is insecure.

Answer

Requests from IP 192.0.2.10 over HTTP are allowed because the deny statement only applies when SecureTransport is false.

Answer

Any IP address can perform GetObject requests if they use HTTPS.

Question 13

A cloud security architect is designing a CI/CD pipeline for a serverless application using AWS Lambda. The application processes sensitive user data and requires encryption at rest and in transit. Which of the following is the BEST approach to securely manage database credentials used by the Lambda function?

Accepted Answer

Use AWS Secrets Manager to store the credentials and retrieve them at runtime with least-privilege IAM roles.. AWS Secrets Manager is the best choice because it is purpose-built for securely storing, rotating, and retrieving secrets such as database credentials. It integrates natively with AWS Lambda via the Secrets Manager API, allowing the function to fetch credentials at runtime using a least-privilege IAM role. This approach avoids embedding secrets in code or configuration and supports automatic rotation, which is critical for compliance with encryption and access control requirements.

Answer

Store the credentials in AWS Systems Manager Parameter Store with a SecureString parameter.

Answer

Store the credentials as encrypted environment variables in the Lambda function configuration.

Answer

Hardcode the credentials in the Lambda function code and encrypt the deployment package.

Question 14

An organization is migrating a legacy application to the cloud and must comply with PCI DSS. The application currently logs credit card numbers in plaintext. Which data security control should be implemented FIRST?

Accepted Answer

Perform data discovery and classification. Before any remediation can be applied, the organization must first perform data discovery and classification to locate where all credit card numbers (PANs) are stored, including logs, databases, and backups. PCI DSS Requirement 3.1 mandates that cardholder data be identified and classified before implementing controls like tokenization or encryption. Without discovery, subsequent controls may miss critical data stores, leaving plaintext PANs exposed.

Answer

Implement tokenization for credit card numbers

Answer

Deploy a data loss prevention (DLP) solution

Answer

Encrypt the database at rest

Question 15

A cloud service provider (CSP) is designing a multi-tenant infrastructure and needs to ensure that a security incident in one tenant's environment does not compromise the confidentiality or integrity of other tenants. The CSP plans to use a combination of network segmentation, hypervisor isolation, and encryption. Which additional control is MOST critical to prevent side-channel attacks that could leak cryptographic keys or other sensitive data across tenants?

Accepted Answer

Ensure cryptographic operations use constant-time algorithms.. Side-channel attacks, such as timing attacks, exploit variations in execution time to infer sensitive data like cryptographic keys. Constant-time algorithms ensure that cryptographic operations execute in a fixed duration regardless of input, eliminating timing variations that could be measured across shared physical hardware. This is critical in multi-tenant environments where tenants share CPU caches and memory buses, as it prevents an attacker from extracting key material through precise timing measurements.

Answer

Implement virtual LANs (VLANs) and firewall rules between tenants.

Answer

Use hardware security modules (HSMs) for key management.

Answer

Enforce strict API rate limiting for each tenant.

Question 16

A company uses a cloud key management service (KMS) and wants to ensure that keys can be used only within a specific geographic region. Which of the following should be configured?

Accepted Answer

Key policy with a condition for allowed regions. Option C is correct because a key policy with a condition using the `kms:CallerRegion` or `aws:RequestRegion` condition key can explicitly restrict the geographic region where the KMS key can be used. This ensures that any cryptographic operation (e.g., Encrypt, Decrypt) attempted from an unauthorized region is denied, enforcing regional data sovereignty requirements.

Answer

VPC endpoint for KMS

Answer

CloudTrail logging

Answer

Key rotation policy

Question 17

Which THREE of the following are key characteristics of cloud computing as defined by NIST SP 800-145?

Accepted Answer

Broad network access. Option A is correct because NIST SP 800-145 defines broad network access as the capability for cloud capabilities to be accessed over the network by standard mechanisms (e.g., HTTPS, SSH, VPN) that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, workstations). This characteristic ensures that resources are available from any location with internet connectivity, not limited to a single physical network segment.

Answer

Location independence

Answer

Dedicated hardware per tenant

Question 18

A multinational corporation uses a cloud CASB to enforce data loss prevention (DLP) policies across SaaS applications. The security team discovers that sensitive data is being exfiltrated via encrypted traffic that the CASB cannot inspect. What is the most effective design change to mitigate this risk?

Accepted Answer

Deploy a forward proxy with SSL/TLS interception capabilities.. Option C is correct because a forward proxy with SSL/TLS interception capabilities allows the CASB to decrypt, inspect, and re-encrypt traffic, enabling DLP policy enforcement on data in transit. This design change addresses the root cause—encrypted traffic bypassing inspection—without breaking application functionality or security.

Answer

Implement user training to prevent data exfiltration.

Answer

Block all encrypted traffic at the network perimeter.

Answer

Disable TLS/SSL encryption for all sensitive data transfers.

Question 19

Which THREE of the following are essential components of a Secure Software Development Lifecycle (SSDLC) for cloud applications?

Accepted Answer

Security regression testing to validate that new code does not reintroduce vulnerabilities.. Security regression testing (C) is essential because it ensures that new code changes do not reintroduce previously fixed vulnerabilities, which is critical in the continuous integration/continuous delivery (CI/CD) pipelines typical of cloud applications. This testing validates that security patches remain effective across rapid iterations, directly supporting the 'verify' phase of the SSDLC.

Answer

Manual penetration testing after every code commit.

Answer

Security awareness training for all developers.

Question 20

Which THREE of the following are key components of a cloud data governance framework?

Accepted Answer

Data retention policies. Data retention policies are a key component of a cloud data governance framework because they define the lifecycle of data, specifying how long data must be kept and when it should be securely deleted. This ensures compliance with legal, regulatory, and business requirements, such as GDPR or HIPAA, and prevents unnecessary storage costs and security risks from outdated data.

Answer

Data masking

Answer

Data encryption at rest
