Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q262-Q267):

NEW QUESTION # 262
Application A runs on Amazon EC2 instances behind a Network Load Balancer (NLB). The EC2 instances are in an Auto Scaling group and are in the same subnet that is associated with the NLB. Other applications from an on-premises environment cannot communicate with Application A on port 8080.
To troubleshoot the issue, a CloudOps engineer analyzes the flow logs. The flow logs include the following records:
ACCEPT from 192.168.0.13:59003 172.31.16.139:8080
REJECT from 172.31.16.139:8080 192.168.0.13:59003
What is the reason for the rejected traffic?

A. The security group of the NLB has no Allow rule for the traffic from the on-premises environment.
B. The ACL of the on-premises environment does not allow traffic to the AWS environment.
C. The security group of the EC2 instances has no Allow rule for the traffic from the NLB.
D. The network ACL that is associated with the subnet does not allow outbound traffic for the ephemeral port range.

Answer: D

Explanation:
VPC Flow Logs show the request arriving and being ACCEPTed on dstport 8080 and the corresponding response being REJECTed on the return path to the client's ephemeral port (59003). AWS networking guidance states that security groups are stateful (return traffic is automatically allowed) while network ACLs are stateless and require explicit inbound and outbound rules for both directions. CloudOps operational guidance for VPC networking further notes that when you allow an inbound request (for example, TCP 8080) through a subnet's network ACL, you must also allow the outbound ephemeral port range (typically 1024?5535) for the response traffic; otherwise, the return packets are dropped and appear as REJECT in flow logs. The observed pattern--request accepted to 8080, response rejected to 59003--matches a missing outbound ephemeral-range allow on the subnet's NACL. Therefore, the cause is the subnet NACL, not security groups or on-premises ACLs. The remediation is to add an outbound ALLOW rule on the NACL for the appropriate ephemeral TCP port range back to the on-premises CIDR (and the corresponding inbound rule if asymmetric).

NEW QUESTION # 263
A company is using an Amazon Aurora MySQL DB cluster that has point-in-time recovery, backtracking, and automatic backups enabled. A CloudOps engineer needs to be able to roll back the DB cluster to a specific recovery point within the previous 72 hours. Restores must be completed in the same production DB cluster.
Which solution will meet these requirements?

A. Create an AWS Lambda function to restore an automatic backup to the existing DB cluster.
B. Create an Aurora Replica. Promote the replica to replace the primary DB instance.
C. Use point-in-time recovery to restore the existing DB cluster to the desired recovery point.
D. Use backtracking to rewind the existing DB cluster to the desired recovery point.

Answer: D

Explanation:
Comprehensive Explanation (250-350 words):
Amazon Aurora backtracking allows a DB cluster to be rewound to a specific point in time without creating a new DB cluster. This feature is designed for fast recovery from logical errors, such as accidental data changes, within a configured backtrack window. Because backtracking operates directly on the existing cluster, it satisfies the requirement that the restore occur in the same production DB cluster.
Point-in-time recovery (Option D) restores data by creating a new DB cluster, which violates the requirement. Option A involves promoting a replica, which does not allow rolling back to an arbitrary historical point. Option B introduces unnecessary complexity and is not supported for restoring directly into the same cluster.
Backtracking provides near-instant rollback and minimal operational disruption, making it the correct solution.

NEW QUESTION # 264
A company is running an ecommerce application on AWS. The application maintains many open but idle connections to an Amazon Aurora DB cluster. During times of peak usage, the database produces the following error message: "Too many connections." The database clients are also experiencing errors.
Which solution will resolve these errors?

A. Configure RDS Proxy. Update the application with the RDS Proxy endpoint.
B. Modify the DB cluster to use a burstable instance type.
C. Turn on enhanced networking for the DB instances.
D. Increase the read capacity units (RCUs) and the write capacity units (WCUs) on the database.

Answer: A

Explanation:
The correct solution is B. Configure RDS Proxy, because RDS Proxy is specifically designed to manage and pool database connections for Amazon Aurora and Amazon RDS. AWS CloudOps documentation states that RDS Proxy reduces database load and prevents connection exhaustion by reusing existing connections and managing spikes in application demand.
In this scenario, the ecommerce application maintains many idle connections, which consume database connection slots even when not actively used. During peak traffic, new connections cannot be established, resulting in the "Too many connections" error. RDS Proxy sits between the application and the Aurora DB cluster, maintaining a smaller, efficient pool of database connections and multiplexing application requests over those connections.

NEW QUESTION # 265
An ecommerce company runs a microservices application on Amazon ECS. Customers sometimes experience high latency when they attempt to complete a purchase through the application. A CloudOps engineer needs a solution to track individual transactions across multiple services to identify where latency is occurring. The solution must require minimal code changes and must provide a visual representation of service dependencies. Which solution will meet these requirements?

A. Set up the AWS X-Ray daemon as a sidecar container. Instrument the application code by using the X-Ray SDK. Use the service map to visualize request flows to identify latency.
B. Use Amazon VPC Flow Logs to collect logs for microservices that run on the ECS container.
Monitor network traffic, and use the service map to identify latency between microservices.
C. Configure an Amazon CloudWatch agent on ECS containers as a sidecar container. Create custom metrics for each service. Set up CloudWatch dashboards to monitor response times.
D. Use Amazon CloudWatch Container Insights as a sidecar container to collect container metrics.Monitor response times, and visualize request flows to identify latency.

Answer: A

Explanation:
AWS X-Ray is the correct service for distributed tracing across microservices. It tracks individual requests as they travel through application components and provides a service map that visually shows dependencies, latency, errors, and bottlenecks. For Amazon ECS, the X-Ray daemon can run as a sidecar container, and the application can be instrumented with the X-Ray SDK. This requires less effort than building custom transaction tracing and gives the CloudOps engineer request-level visibility across services. CloudWatch agents and Container Insights provide metrics and logs, but they do not trace individual user transactions across multiple services. VPC Flow Logs capture network metadata, not application-level request traces or service dependency maps. Therefore, X-Ray with a sidecar daemon and SDK instrumentation is the correct CloudOps monitoring solution.

NEW QUESTION # 266
An Amazon EC2 instance is running an application that uses Amazon Simple Queue Service (Amazon SQS) queues. A CloudOps engineer must ensure that the application can read, write, and delete messages from the SQS queues.
Which solution will meet these requirements in the MOST secure manner?

A. Create and associate an IAM role that allows EC2 instances to call AWS services. Attach an IAM policy to the role that allows the sqs:SendMessage permission, the sqs:ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues.
B. Create an IAM user with an IAM policy that allows the sqs:SendMessage permission, the sqs:
ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues. Export the IAM user's access key and secret access key as environment variables on the EC2 instance.
C. Create and associate an IAM role that allows EC2 instances to call AWS services. Attach an IAM policy to the role that allows sqs:* permissions to the appropriate queues.
D. Create an IAM user with an IAM policy that allows the sqs:SendMessage permission, the sqs:
ReceiveMessage permission, and the sqs:DeleteMessage permission to the appropriate queues. Embed the IAM user's credentials in the application's configuration.

Answer: A

Explanation:
The most secure pattern is to use an IAM role for Amazon EC2 with the minimum required permissions.
AWS guidance states: "Use roles for applications that run on Amazon EC2 instances" and "grant least privilege by allowing only the actions required to perform a task." By attaching a role to the instance, short- lived credentials are automatically provided through the instance metadata service; this removes the need to create long-term access keys or embed secrets. Granting only sqs:SendMessage, sqs:ReceiveMessage, and sqs:DeleteMessage against the specific SQS queues enforces least privilege and aligns with CloudOps security controls. Options A and B rely on IAM user access keys, which contravene best practices for workloads on EC2 and increase credential-management risk. Option C uses a role but grants sqs:*, violating least-privilege principles. Therefore, Option D meets the security requirement with scoped, temporary credentials and precise permissions.
