質問 # 275
A CloudOps engineer launches two Amazon EC2 instances and creates a single public subnet for testing purposes in the same Availability Zone. The CloudOps engineer wants Amazon Route 53 to respond with a public IP address only if a test webpage on an instance is running. However, even when the test webpage is unavailable, Route 53 still responds with the public IP addresses from both instances. How can the CloudOps engineer resolve this issue?
正解：B
解説：
Route 53 multivalue answer routing can return multiple IP addresses and can be combined with health checks so only healthy records are returned. AWS documentation states that when a health check is associated with a multivalue answer record, Route 53 responds with the corresponding IP address only when the health check is healthy. The current problem occurs because Route 53 is returning both IPs even when the webpage is down, which indicates that health checks are not being used correctly. Latency-based routing is used to route users to lower- latency endpoints across Regions, not to return multiple tested instance IPs in the same subnet.
Weighted routing distributes traffic based on weights but does not solve this specific "return only healthy IPs" requirement unless paired with health checks. Another subnet is irrelevant.

A company stores critical information in an Amazon RDS for PostgreSQL database. The company notices degraded performance, high CPU utilization, increased query latency, and connection timeouts during peak shopping hours. The company also identifies surges in user connections during peak hours. The connection surges affect the read performance of the database.
The company wants to resolve the database performance issues.
Which combination of steps will meet this requirement? (Select TWO.)
正解：D、E
解説：
The symptoms point to two common database pressure sources: inefficient queries (driving high CPU and latency) and excessive concurrent connections (driving connection management overhead, read contention, and timeouts). The most effective remediation is to address both the SQL workload and the connection surge behavior.
Amazon RDS Performance Insights (Option A) is designed to help identify which SQL statements and wait events contribute most to database load. It provides a database-centric view of performance that highlights top SQL, top waits, and the relative impact of sessions on CPU and other resources. By using Performance Insights to pinpoint the highest-impact SQL and then tuning those queries (for example, improving indexes, reducing full scans, and optimizing query patterns), the company can lower CPU utilization and reduce query latency during peak hours.
Connection surges are best addressed with a managed connection pooling layer. RDS Proxy (Option E) provides connection pooling and multiplexing between application connections and the database, which reduces the overhead of establishing and maintaining a large number of database connections. During spikes, the proxy can smooth bursty connection behavior, improve failover handling, and reduce the risk of overwhelming the database with too many concurrent connections. This directly targets the observed timeouts and read performance degradation tied to surges.
Option B is not the best fit because CloudWatch Logs Insights is a log analytics tool; it is not the primary mechanism for deep SQL performance attribution in RDS and typically requires extensive logging configurations that add overhead. Option C would reduce availability and does not improve performance.
Option D would make the problem worse: disabling pooling increases connection churn and overhead, amplifying timeouts and latency during peak traffic.
Therefore, combining Performance Insights query analysis/tuning with RDS Proxy connection pooling best resolves both root causes.

A CloudOps engineer must ensure that all of a company's current and future Amazon S3 buckets have logging enabled. If an S3 bucket does not have logging enabled, an automated process must enable logging for the S3 bucket.
Which solution will meet these requirements?
正解：D
解説：
AWS Config is designed to continuously evaluate AWS resource configurations and detect noncompliance.
The s3-bucket-logging-enabled managed rule specifically checks whether server access logging is enabled on S3 buckets. This directly meets the detection requirement for both current and future buckets.
To satisfy the remediation requirement, AWS Config supports automatic remediation actions. Using the AWS-provided AWS-ConfigureS3BucketLogging Systems Manager Automation runbook enables logging without custom code. This reduces operational overhead, avoids Lambda function maintenance, and aligns with AWS best practices.
Option A is incorrect because Trusted Advisor does not support automatic remediation. Option B cannot enforce logging at creation time through bucket policies alone. Option C works but introduces unnecessary Lambda maintenance compared to using an AWS-managed automation runbook.
Thus, combining AWS Config managed rules with Systems Manager Automation provides continuous compliance with minimal operational effort.
質問 # 278
A company has a VPC that contains a public subnet and a private subnet. The company deploys an Amazon EC2 instance that uses an Amazon Linux Amazon Machine Image (AMI) and has the AWS Systems Manager Agent (SSM Agent) installed in the private subnet. The EC2 instance is in a security group that allows only outbound traffic.
A CloudOps engineer needs to give a group of privileged administrators the ability to connect to the instance through SSH without exposing the instance to the internet.
Which solution will meet this requirement?
正解：B
解説：
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Doocuments:
EC2 Instance Connect Endpoint (EIC Endpoint) enables SSH to instances in private subnets without public IPs and without needing to traverse the public internet. CloudOps guidance explains that you deploy the endpoint in the same VPC/subnet as the targets, then allow inbound SSH on the instance security group from the endpoint's security group. Access is governed by IAM-administrators must have Instance Connect permissions; while the example uses a broad policy, the key mechanism is EIC in the private subnet plus SG rules scoped to the endpoint. Systems Manager Session Manager can provide shell access without SSH, but the requirement explicitly states "connect through SSH," making EIC the purpose-built solution.
Options B and D misuse Systems Manager for SSH and propose unnecessary SG changes or incorrect endpoint placement; Option C places the endpoint in a public subnet, which is not required for private SSH access. Therefore, creating an EC2 Instance Connect endpoint in the private subnet and updating SGs accordingly meets the requirement while keeping the instance non-internet-exposed.

質問 # 279
A company's ecommerce application is running on Amazon EC2 instances that are behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. Customers report that the website is occasionally down. When the website is down, it returns an HTTP 500 (server error) status code to customer browsers.
The Auto Scaling group's health check is configured for EC2 status checks, and the instances appear healthy.
Which solution will resolve the problem?
正解：A
解説：
In this scenario, the EC2 instances pass their EC2 status checks, indicating that the operating system is responsive. However, the application hosted on the instance is failing intermittently, returning HTTP 500 errors. This demonstrates a discrepancy between the instance-level health and the application-level health.
According to AWS CloudOps best practices under Monitoring, Logging, Analysis, Remediation and Performance Optimization (SOA-C03 Domain 1), Auto Scaling groups should incorporate Elastic Load Balancing (ELB) health checks instead of relying solely on EC2 status checks. The ELB health check probes the application endpoint (for example, HTTP or HTTPS target group health checks), ensuring that the application itself is functioning correctly.
When an instance fails an ELB health check, Amazon EC2 Auto Scaling will automatically mark the instance as unhealthy and replace it with a new one, ensuring continuous availability and performance optimization.
Extract from AWS CloudOps (SOA-C03) Study Guide - Domain 1:
"Implement monitoring and health checks using ALB and EC2 Auto Scaling integration. Application Load Balancer health checks allow Auto Scaling to terminate and replace instances that fail application-level health checks, ensuring consistent application performance." Extract from AWS Auto Scaling Documentation:
"When you enable the ELB health check type for your Auto Scaling group, Amazon EC2 Auto Scaling considers both EC2 status checks and Elastic Load Balancing health checks to determine instance health. If an instance fails the ELB health check, it is automatically replaced." Therefore, the correct answer is B, as it ensures proper application-level monitoring and remediation using ALB-integrated ELB health checks-a core CloudOps operational practice for proactive incident response and availability assurance.
