Amazon AWS Certified CloudOps Engineer - Associate Sample Questions (Q98-Q103):NEW QUESTION # 98
A company is running a custom database on an Amazon EC2 instance. The database stores its data on an Amazon Elastic Block Store (Amazon EBS) volume. A SysOps administrator must set up a backup strategy for the EBS volume.
What should the SysOps administrator do to meet this requirement?
  • A. Create an Amazon Data Lifecycle Manager (Amazon DLM) policy to take a snapshot of the EBS volume on a recurring schedule.
  • B. Create an Amazon CloudWatch alarm for the VolumeIdleTime metric with an action to take a snapshot of the EBS volume.
  • C. Create a pipeline in AWS Data Pipeline to take a snapshot of the EBS volume on a recurring schedule.
  • D. Create an AWS DataSync task to take a snapshot of the EBS volume on a recurring schedule.
Answer: A
Explanation:
Amazon Data Lifecycle Manager (DLM) is the AWS service specifically designed to automate the creation, retention, and deletion of EBS snapshots.
With DLM, you can:
- Automatically create snapshots on a recurring schedule (e.g., daily, hourly).
- Retain snapshots for a specific number of days.
- Delete old snapshots automatically to save costs.
- Ensure consistent and automated backups without manual intervention.
This approach fully meets the company's requirement for a backup strategy for the EBS volume.

NEW QUESTION # 99
A multinational company uses an organization in AWS Organizations to manage over 200 member accounts across multiple AWS Regions. The company must ensure that all AWS resources meet specific security requirements.
The company must not deploy any EC2 instances in the ap-southeast-2 Region. The company must completely block root user actions in all member accounts. The company must prevent any user from deleting AWS CloudTrail logs, including administrators. The company requires a centrally managed solution that the company can automatically apply to all existing and future accounts. Which solution will meet these requirements?
  • A. Configure AWS Firewall Manager with security policies to meet the security requirements. Use an AWS Config aggregator with organization-wide conformance packs to detect security policy violations.
  • B. Use AWS Control Tower for account governance. Configure Region deny controls. Use Service Control Policies (SCPs) to restrict root user access.
  • C. Enable AWS Security Hub across the organization. Create custom security standards to enforce the security requirements. Use AWS CloudFormation StackSets to deploy the standards to all the accounts in the organization. Set up Security Hub automated remediation actions.
  • D. Create AWS Config rules with remediation actions in each account to detect policy violations.
    Implement IAM permissions boundaries for the account root users.
Answer: B
Explanation:
AWS CloudOps governance best practices emphasize centralized account management and preventive guardrails. AWS Control Tower integrates directly with AWS Organizations and provides "Region deny controls" and "Service Control Policies (SCPs)" that apply automatically to all existing and newly created member accounts. SCPs are organization-wide guardrails that define the maximum permissions for accounts. They can explicitly deny actions such as launching EC2 instances in a specific Region, or block root user access.
To prevent CloudTrail log deletion, SCPs can also include denies on cloudtraileleteTrail and s3eleteObject actions targeting the CloudTrail log S3 bucket. These SCPs ensure that no user, including administrators, can violate the compliance requirements.
"Use AWS Control Tower to establish a secure, compliant, multi-account environment with preventive guardrails through service control policies and detective controls through AWS Config." This approach meets all stated needs: centralized enforcement, automatic propagation to new accounts, region-based restrictions, and immutable audit logs. Options A, B, and D either detect violations reactively or lack complete enforcement and automation across future accounts.

NEW QUESTION # 100
A company is migrating a legacy application to AWS. The application runs on EC2 instances across multiple Availability Zones behind an Application Load Balancer (ALB). The target group routing algorithm is set to weighted random, and the application requires session affinity (sticky sessions).
After deployment, users report random application errors that were not present before migration, even though target health checks are passing.
Which solution will meet this requirement?
  • A. Turn on anomaly mitigation for the target group.
  • B. Set the routing algorithm of the target group to least outstanding requests.
  • C. Turn off the cross-zone load balancing attribute of the target group.
  • D. Increase the deregistration delay attribute of the target group.
Answer: B
Explanation:
According to the AWS Cloud Operations and Elastic Load Balancing documentation, Application Load Balancer (ALB) supports multiple routing algorithms to distribute requests among targets:
Round robin (default)
Least outstanding requests (LOR)
Weighted random
When applications require session affinity, AWS recommends using "least outstanding requests" as the load balancing algorithm because it reduces latency, distributes load evenly, and ensures consistent target responsiveness during high traffic.
Using weighted random routing with sticky sessions can cause sessions to be routed inconsistently if one target's capacity fluctuates, leading to session mismatches and application errors - especially when user sessions rely on instance-specific state.
Disabling cross-zone balancing (Option C) or adjusting deregistration delay (Option D) does not address routing inconsistency. Anomaly mitigation (Option B) protects against target performance degradation, not sticky-session misrouting.
Therefore, the correct solution is Option A - changing the target group's routing algorithm to least outstanding requests ensures smoother, predictable session handling and resolves random application errors.

NEW QUESTION # 101
A company's security policy requires incoming SSH traffic to be restricted to a defined set of addresses. The company is using an AWS Config rule to check whether security groups allow unrestricted incoming SSH traffic.
A CloudOps engineer discovers a noncompliant resource and fixes the security group manually.
The CloudOps engineer wants to automate the remediation of other noncompliant resources.
What is the MOST operationally efficient solution that meets these requirements?
  • A. Configure an Amazon EventBridge rule for AWS Config configuration item change events. Create an AWS Lambda function that can remove the noncompliant rule from the security group Configure the rule to invoke the Lambda function.
  • B. Create an Amazon CloudWatch alarm for the AWS Config rule's status metric. Create an AWS Lambda function that can remove the noncompliant rule from the security group. Configure the alarm action to invoke the Lambda function.
  • C. Configure an automatic remediation action on the AWS Config rule. Specify the AWS- DisablolncomingSSHOnPort22 remediation action.
  • D. Create an AWS Lambda function that can analyze a security group's inbound rules to check for unrestricted SSH access. Configure the Lambda function to remove the noncompliant rule from the security group. Configure an Amazon EventBridge rule to invoke the Lambda function every hour.
Answer: C
Explanation:
AWS Config supports automatic remediation by invoking a Systems Manager Automation runbook when a rule is noncompliant. For unrestricted SSH, you can attach the managed remediation action AWS-DisableIncomingSSHOnPort22 to the existing AWS Config rule so that any noncompliant security group is automatically corrected without custom Lambda code or polling logic.

NEW QUESTION # 102
A company's architecture team must receive immediate email notifications whenever new Amazon EC2 instances are launched in the company's main AWS production account.
What should a CloudOps engineer do to meet this requirement?
  • A. Create a user data script that sends an email message through a smart host connector. Include the architecture team's email address in the user data script as the recipient. Ensure that all new EC2 instances include the user data script as part of a standardized build process.
  • B. Create an Amazon Simple Notification Service (Amazon SNS) topic and a subscription that uses the email protocol. Enter the architecture team's email address as the subscriber. Create an Amazon EventBridge rule that reacts when EC2 instances are launched. Specify the SNS topic as the rule's target.
  • C. Create an Amazon Simple Queue Service (Amazon SQS) queue and a subscription that uses the email protocol. Enter the architecture team's email address as the subscriber. Create an Amazon EventBridge rule that reacts when EC2 instances are launched. Specify the SQS queue as the rule's target.
  • D. Create an Amazon Simple Notification Service (Amazon SNS) topic. Configure AWS Systems Manager to publish EC2 events to the SNS topic. Create an AWS Lambda function to poll the SNS topic. Configure the Lambda function to send any messages to the architecture team's email address.
Answer: B
Explanation:
As per the AWS Cloud Operations and Event Monitoring documentation, the most efficient method for event-driven notification is to use Amazon EventBridge to detect specific EC2 API events and trigger a Simple Notification Service (SNS) alert.
EventBridge continuously monitors AWS service events, including RunInstances, which signals the creation of new EC2 instances. When such an event occurs, EventBridge sends it to an SNS topic, which then immediately emails subscribed recipients - in this case, the architecture team.
This combination provides real-time, serverless notifications with minimal management. SQS (Option C) is designed for queue-based processing, not direct user alerts. User data scripts (Option A) and custom polling with Lambda (Option D) introduce unnecessary operational complexity and latency.
Hence, Option B is the correct and AWS-recommended CloudOps design for immediate launch notifications.
