Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q131-Q136):

NEW QUESTION # 131
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?

Answer: A

Explanation:
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 # 132
A company that runs multiple workloads on AWS wants to enhance its security posture by implementing DNS-based threat protection. The company must block DNS-based attacks.
Which solution will meet this requirement?

Answer: A

Explanation:
Amazon Route 53 Resolver DNS Firewall provides DNS-based threat protection by allowing you to create rule groups that block queries to known malicious domains and apply domain filtering policies across your VPCs. By configuring the Route 53 Resolver to forward DNS queries through the DNS Firewall, you ensure that all DNS traffic is inspected and filtered, effectively blocking DNS-based attacks and malicious domains while keeping DNS resolution within your AWS environment.


NEW QUESTION # 133
An errant process is known to use an entire processor and run at 100% CPU. A CloudOps engineer wants to automate restarting an Amazon EC2 instance when the problem occurs for more than 2 minutes.
How can this be accomplished?

Answer: D

Explanation:
To detect CPU utilization issues within a 2-minute window, detailed monitoring is required. Basic monitoring publishes metrics at 5-minute intervals, which is too coarse to reliably detect a condition lasting only 2 minutes. Detailed monitoring publishes metrics at 1-minute granularity, allowing precise detection.
Amazon CloudWatch alarms support EC2 reboot actions directly, eliminating the need for custom Lambda functions. This minimizes administrative overhead and leverages native AWS integrations.
Options C and D introduce unnecessary complexity and delay. Option A cannot meet the timing requirement due to metric granularity.
Therefore, using a CloudWatch alarm with detailed monitoring and an EC2 reboot action is the correct solution.


NEW QUESTION # 134
A CloudOps engineer created a VPC with a private subnet, a security group allowing all outbound traffic, and an endpoint for EC2 Instance Connect in the private subnet. The EC2 instance was launched without an SSH key pair, using the same subnet and security group. However, the engineer cannot connect via EC2 Instance Connect endpoint.
How can the CloudOps engineer connect to the instance?

Answer: D

Explanation:
According to the AWS Cloud Operations and EC2 Connectivity documentation, EC2 Instance Connect Endpoint allows access to instances without internet exposure or open SSH ports. However, for successful connectivity, the EC2 instance must have Systems Manager permissions through an IAM instance profile.
If no IAM instance profile is attached, the instance cannot establish a control channel with the Systems Manager service, and EC2 Instance Connect cannot authenticate the session.
Opening port 22 (Option B) is unnecessary and contradicts the private subnet design. HTTPS rules (Option A) are irrelevant because EC2 Instance Connect communicates through AWS APIs, not direct HTTPS connections. Recreating the instance with a key pair (Option D) bypasses the intended keyless connection mechanism.
Therefore, Option C - attaching an IAM instance profile with Systems Manager permissions - enables secure, private access through EC2 Instance Connect Endpoint.


NEW QUESTION # 135
A company maintains a list of 75 approved Amazon Machine Images (AMIs) that can be used across an organization in AWS Organizations. The company's development team has been launching Amazon EC2 instances from unapproved AMIs.
A SysOps administrator must prevent users from launching EC2 instances from unapproved AMIs.
Which solution will meet this requirement?

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract of AWS CloudOps Documents:
The requirement is preventative: stop users from launching from unapproved AMIs. The most scalable approach with 75 approved AMIs is to tag all approved AMIs (for example, ApprovedAMI=true) and enforce usage through an IAM policy condition that only allows ec2:RunInstances when the ec2:ImageId resource (the AMI) includes the required tag. This avoids maintaining long allow/deny lists of AMI IDs and supports continuous updates: as new approved AMIs are created, tagging them automatically brings them under the policy without policy rewrites.
Option B is incorrect because service-linked roles are used by AWS services, not assigned to users for interactive authorization enforcement in this way. Option C and D are detective/remedial controls that act after instances are already launched, which does not satisfy "must prevent." They also increase operational overhead and risk disruptions.

NEW QUESTION # 136
......

Life is beset with all different obstacles that are not easily overcome. For instance, SOA-C03 exams may be insurmountable barriers for the majority of population. However, with the help of our exam test, exams are no longer problems for you. The reason why our SOA-C03 Training Materials outweigh other study prep can be attributed to three aspects, namely free renewal in one year, immediate download after payment and simulation for the software version.
