20+ practice questions focused on Continuous Improvement for Existing Solutions — one of the most tested topics on the AWS Certified Solutions Architect Professional SAP-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Continuous Improvement for Existing Solutions PracticeMatch each AWS monitoring and logging service to its capability.
Explanation: CloudWatch provides observability via metrics and logs (correct). GuardDuty detects threats with ML (correct). CloudTrail records API activity for auditing, not resource configuration changes, so B is incorrect. AWS Config tracks resource configuration changes, not API activity, so C is incorrect.
A company uses Amazon ElastiCache for Redis to cache frequently accessed data. The cache cluster is a single node (cache.r5.large). Over time, the cache hit ratio has decreased, and the CPU utilization is consistently above 80%. What should a solutions architect do to improve performance?
Explanation: Enabling cluster mode distributes data across multiple shards, reducing CPU load on individual nodes and improving the cache hit ratio by allowing more efficient use of memory and processing. Option A is incorrect because reducing TTL would cause more cache misses, further degrading the hit ratio. Option B is incorrect because read replicas offload read traffic but do not reduce CPU utilization caused by high write activity or data management. Option C is incorrect because scaling up to a larger node type provides more resources but does not address the architectural limitation of a single node; the increased CPU utilization is due to the single node being overwhelmed, not just resource capacity.
A company uses Amazon S3 to store critical data. They need to ensure that data is automatically replicated to another AWS Region for disaster recovery. Which configuration meets this requirement with minimal operational overhead?
Explanation: S3 Cross-Region Replication (CRR) automatically replicates objects to a destination bucket in a different AWS Region, providing disaster recovery with minimal operational overhead. Option A is wrong because S3 Versioning alone does not replicate data. Option B is wrong because S3 Transfer Acceleration speeds up uploads but does not replicate data. Option C is wrong because S3 Lifecycle policies manage storage tiers, not replication.
A company runs a containerized application on Amazon ECS with Fargate launch type. The application needs to access an S3 bucket. The ECS task role has the necessary S3 permissions. However, the application is unable to upload files to S3. What is the MOST likely cause?
Explanation: For an ECS Fargate task to access S3, the task role with the necessary permissions must be specified in the task definition. If the task role ARN is incorrect or missing, the container will not be able to assume the role, causing S3 access failures. Option A is wrong because the task execution role is used only by the ECS agent to pull container images and send logs, not for application-level S3 access. Option B is wrong because the question states that the task role already has the required S3 permissions, so the bucket policy is likely not the issue. Option C is wrong because an S3 VPC endpoint is not required if the task can reach S3 through the internet or a NAT gateway; its absence would not prevent uploads if proper routing exists.
A company applies the above IAM policy to an IAM user. The user attempts to upload an object to my-bucket using the AWS CLI with the command: aws s3 cp file.txt s3://my-bucket/. What is the outcome?
Explanation: The Deny statement with StringNotEquals on s3:x-amz-server-side-encryption denies any PutObject that does not specify SSE-S3 (AES256). Since the CLI command does not include any encryption header, the Deny condition matches and the request is denied. Option A is incorrect because evaluation order does not matter; an explicit Deny always overrides an Allow. Option C is incorrect because the Allow statement requires encryption, which is not provided. Option D is incorrect because the Deny statement applies precisely when no encryption header is present.
