Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q159-Q164):

NEW QUESTION # 159
A company has deployed Amazon EC2 instances from custom Amazon Machine Images (AMIs) in two AWS Regions. The company registered all the instances with AWS Systems Manager.
The company discovers that the operating system on some instances has a significant zero-day exploit.
However, the company does not know how many instances are affected.
A CloudOps engineer must implement a solution to deploy operating system patches for the affected EC2 instances.
Which solution will meet this requirement with the LEAST operational overhead?

Answer: B

Explanation:
Because all instances are already managed by AWS Systems Manager, the lowest-overhead approach is to use Systems Manager Patch Manager end-to-end. Patch Manager is built specifically to scan managed instances for missing patches and to apply operating system patches according to defined rules. By defining a patch baseline, the CloudOps engineer establishes which patches are approved (and how quickly critical patches are approved), plus any exclusions and compliance rules. A Patch Manager scan can then be run to determine which instances are noncompliant and therefore likely affected by the vulnerability, without the engineer needing to manually inventory hosts.
After identifying affected (noncompliant) instances through the scan results, Patch Manager can apply patches directly using Patch Now (or an equivalent on-demand patch operation) in each Region. This matches the multi-Region requirement while keeping operations simple: no custom code, no additional services, and no complex event orchestration. It also produces compliance visibility in Systems Manager, which helps track remediation status for incident response.
Option B adds AWS Config unnecessarily. AWS Config is useful for recording and evaluating configuration changes and can report compliance against configuration rules, but it is not the most direct tool for identifying missing OS patches on instances already under Systems Manager management. Option C introduces additional moving parts (EventBridge rules and event-driven automation). While it can be powerful, it is more complex than a straightforward Patch Manager scan-and-patch workflow, and it assumes the right compliance events exist for this scenario before remediation begins. Option D is the highest operational burden because it requires rebuilding AMIs, launching replacement instances, and coordinating replacements across two Regions. That approach aligns to immutable infrastructure patterns, but it is not the least overhead for rapid remediation of existing instances.
Therefore, using Patch Manager with a patch baseline, scanning to identify affected instances, and applying patches in each Region is the simplest and most operationally efficient solution.


NEW QUESTION # 160
A company requires the rotation of administrative credentials for production workloads on a regular basis. A CloudOps engineer must implement this policy for an Amazon RDS DB instance's master user password.
Which solution will meet this requirement with the LEAST operational effort?

Answer: B

Explanation:
AWS Secrets Manager natively supports credential management and automatic rotation for Amazon RDS master user passwords. When a secret is associated with an RDS instance, Secrets Manager automatically updates the password both in the secret and on the database, without downtime or manual scripting.
AWS documentation confirms:
"AWS Secrets Manager can automatically rotate the master user password for Amazon RDS databases. Rotation is fully managed and integrated, requiring no custom code or maintenance." Option A introduces unnecessary Lambda automation. Option B and C use Parameter Store, which does not provide direct RDS password rotation. Therefore, Option D achieves secure, automatic credential rotation with least operational effort, fully aligned with CloudOps security automation principles.

NEW QUESTION # 161
A company's financial department needs to view the cost details of each project in an AWS account. A CloudOps engineer must perform the initial configuration that is required to view cost for each project in Cost Explorer. Which solution will meet this requirement?

Answer: C

Explanation:
Cost allocation tags allow AWS costs to be categorized by project in Cost Explorer. After activating the relevant tag as a cost allocation tag, the company can apply a project-specific tag to resources and then filter or group Cost Explorer data by that tag to view costs for each project.


NEW QUESTION # 162
A company has a microservice that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). A CloudOps engineer must use Amazon Route 53 to create a record that maps the ALB URL to example.com.
Which type of Route 53 record will meet this requirement?

Answer: A

Explanation:
Route 53 alias records are designed to map custom domain names to AWS resources such as ALBs, CloudFront distributions, and S3 website endpoints. Alias records behave like A records but point to AWS- managed resources instead of IP addresses.
Alias records are preferred over CNAME records because they can be used at the zone apex (example.com), do not incur additional DNS query charges, and automatically track changes to the underlying AWS resource.
A and AAAA records require fixed IP addresses, which ALBs do not provide. CNAME records cannot be used at the root domain.
Therefore, an alias record is the correct solution.


NEW QUESTION # 163
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?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Doocuments:
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-
65535) 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).
