Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) Sample Questions (Q280-Q285):

NEW QUESTION # 280
A SysOps administrator is deploying an application on 10 Amazon EC2 instances. The application must be highly available. The instances must be placed on distinct underlying hardware.
What should the SysOps administrator do to meet these requirements?

A. Launch the instances into a spread placement group in single AWS Region
B. Launch the instances into a partition placement group in multiple AWS Regions.
C. Launch the instances into a spread placement group in multiple AWS Regions.
D. Launch the instances into a cluster placement group in a single AWS Region.

Answer: A

Explanation:

NEW QUESTION # 281
A company is experiencing issues with legacy software running on Amazon EC2 instances. Errors occur when the total CPU utilization on the EC2 instances exceeds 80%. A short-term solution is required while the software is being rewritten. A SysOps administrator is tasked with creating a solution to restart the instances when the CPU utilization rises above 80%.
Which solution meets these requirements with the LEAST operational overhead?

A. Create an Amazon EventBridge rule using the predefined patterns for CPU utilization of the EC2 instances. When utilization exceeds 80%, invoke an AWS Lambda function to restart the instances.
B. Add an Amazon CloudWatch alarm for CPU utilization and configure the alarm action to reboot the EC2 instances.
C. Add an Amazon CloudWatch alarm for CPU utilization and configure an AWS Systems Manager Automation runbook to reboot the EC2 instances when utilization exceeds 80%.
D. Write a script that monitors the CPU utilization of the EC2 instances and reboots the instances when utilization exceeds 80%. Run the script as a cron job.

Answer: B

Explanation:
The simplest and most efficient solution to ensure that EC2 instances are restarted when CPU utilization exceeds 80% is to use Amazon CloudWatch alarms:
* Create a CloudWatch Alarm: Navigate to the CloudWatch dashboard in the AWS Management Console and create a new alarm. Set the alarm to monitor the CPU utilization metric of the EC2 instances.
* Set the Alarm Condition: Configure the alarm to trigger when the CPU utilization exceeds 80%. You can specify this threshold in the alarm settings.
* Configure Alarm Actions: In the actions settings of the alarm, select the option to reboot the instance.
This action ensures that the instance is automatically restarted whenever the alarm condition is met, without the need for manual intervention or additional scripts.
This method leverages AWS's native capabilities, minimizing operational overhead and eliminating the need for external tools or custom scripts.

NEW QUESTION # 282
A company is using Amazon Elastic Container Sen/ice (Amazon ECS) to run a containerized application on Amazon EC2 instances. A SysOps administrator needs to monitor only traffic flows between the ECS tasks.
Which combination of steps should the SysOps administrator take to meet this requirement? (Select TWO.)

A. Configure Amazon CloudWatch Logs on the elastic network interface of each task.
B. Configure VPC Flow Logs on the elastic network interface of each task.
C. Specify the host network mode in the task definition.
D. Specify the awsvpc network mode in the task definition.
E. Specify the bridge network mode in the task definition.

Answer: B,D

Explanation:
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-networking-awsvpc.html To monitor traffic flows between ECS tasks, you need to use VPC Flow Logs and specify the awsvpc network mode in the task definition.
* VPC Flow Logs:
* VPC Flow Logs capture information about the IP traffic going to and from network interfaces in your VPC.
* Enable VPC Flow Logs on the elastic network interfaces (ENIs) used by the ECS tasks.
* awsvpc Network Mode:
* The awsvpc network mode gives each task its own ENI, allowing for more granular network monitoring and security controls.
* This mode is required to capture detailed traffic flow information for each ECS task.

NEW QUESTION # 283
A company's AWS Lambda function is experiencing performance issues. The Lambda function performs many CPU-intensive operations. The Lambda function is not running fast enough and is creating bottlenecks in the system.
What should a SysOps administrator do to resolve this issue?

A. Increase the amount of memory for the Lambda function.
B. In the CPU launch options for the Lambda function, activate hyperthreading.
C. Turn off the AWS managed encryption.
D. Load the required code into a custom layer.

Answer: A

NEW QUESTION # 284
A company has an ecommerce application. The application runs on Amazon EC2 instances that are in an Auto Scaling group. The company runs a backend PostgreSQL database on Amazon RDS. As the number of EC2 instances increases during times of high application usage, the database's CPU utilization increases. At the same time, the database's available memory significantly decreases. A SysOps administrator must reduce the overhead of the new database connections from the Auto Scaling group in a highly available manner.
Which solution will meet this requirement?

A. Launch another EC2 instance. Install and configure PgBouncer with the existing PostgreSQL database connection string.
B. Create an RDS proxy. Configure connectivity to the existing PostgreSQL database.
C. Enable the RDS Multi-AZ feature.
D. Enable RDS Performance Insights.

Answer: B

Explanation:
Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon RDS that helps improve the scalability, availability, and security of database applications. It allows applications to pool and share database connections, reducing the overhead associated with opening and closing connections, which can be particularly beneficial in scenarios with fluctuating workloads, such as those managed by Auto Scaling groups.
By implementing RDS Proxy, you can:
* Reduce CPU and Memory Overhead:By managing a pool of connections, RDS Proxy reduces the number of active connections to the database, thereby decreasing the CPU and memory usage on the RDS instance.
* Improve Application Scalability:RDS Proxy can handle a large number of simultaneous connections, making it easier to scale applications without overloading the database.
* Enhance Availability:In the event of a database failover, RDS Proxy can automatically connect to a standby database instance, preserving application connections and reducing failover times.
Therefore, creating an RDS Proxy and configuring it to connect to the existing PostgreSQL database is the most effective solution to meet the company's requirements.
