Amazon AWS Certified SysOps Administrator - Associate (SOA-C02) 認定 SOA-C02 試験問題 (Q500-Q505):

質問 # 500
A company runs a worker process on three Amazon EC2 instances. The instances are in an Auto Scaling group that is configured to use a simple scaling policy. The instances process messages from an Amazon Simple Queue Service (Amazon SQS) queue.
Random periods of increased messages are causing a decrease in the performance of the worker process. A SysOps administrator must scale the instances to accommodate the increased number of messages.
Which solution will meet these requirements?

A. Create an Application Load Balancer (ALB). Attach the ALB to the Auto Scaling group. Create a target tracking scaling policy for the ALBRequestCountPerTarget metric to modify the Auto Scaling group.
B. Create an Application Load Balancer (ALB). Attach the ALB to the Auto Scaling group. Create a scheduled scaling policy for the Auto Scaling group.
C. Use CloudWatch to create a metric math expression to calculate the approximate age of the oldest message in the SQS queue. Create a target tracking scaling policy for the metric math expression to modify the Auto Scaling group.
D. Use CloudWatch to create a metric math expression to calculate the approximate number of messages visible in the SQS queue for each instance. Create a target tracking scaling policy for the metric math expression to modify the Auto Scaling group.

正解：D

質問 # 501
A company needs to monitor the disk utilization of Amazon Elastic Block Store (Amazon EBS) volumes The EBS volumes are attached to Amazon EC2 Linux Instances A SysOps administrator must set up an Amazon CloudWatch alarm that provides an alert when disk utilization increases to more than 80%.
Which combination of steps must the SysOps administrator lake lo meet these requirements? (Select THREE.)

A. Configure a CloudWatch alarm to enter ALARM state when the disk_used CloudWatch metric is greater than 80% or when the disk_free CloudWatch metric is less than 20%.
B. Configure a CloudWatch alarm to enter ALARM state when the disk_used_percent CloudWatch metric is greater than 80%.
C. Install and start the CloudWatch agent by using an 1AM role. Attach the Cloud Watch AgentServerPolicy AWS managed policy to the role.
D. Install and start the CloudWatch agent by using AWS Systems Manager or the command line
E. Create an 1AM role that includes the CloudWatchApplicationInsightsReadOnlyAccess AWS managed policy. Attach the role to the instances
F. Create an 1AM role that includes the Cloud Watch AgentServerPol icy AWS managed policy Attach me role to the instances

正解：B、D、F

解説：
* Create an IAM role with the CloudWatchAgentServerPolicy:
This policy grants the necessary permissions for the CloudWatch agent to collect and send metrics.
Steps:
Go to the AWS Management Console.
Navigate to IAM and create a new role.
Choose "EC2" as the trusted entity.
Attach the "CloudWatchAgentServerPolicy" managed policy to the role.
Attach this IAM role to your EC2 instances.
Reference:
* Install and start the CloudWatch agent:
The CloudWatch agent must be installed and configured to collect disk utilization metrics.
Steps:
Use AWS Systems Manager or SSH to connect to your instances.
Install the CloudWatch agent using the following commands:
sudo yum install amazon-cloudwatch-agent
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -c file:/path/to/your-config-file.json -s Start the agent:
sudo systemctl start amazon-cloudwatch-agent
Configure a CloudWatch alarm:
Create an alarm based on the disk_used_percent metric.
Steps:
Go to the AWS Management Console.
Navigate to CloudWatch and select "Alarms" from the left-hand menu.
Click on "Create alarm."
Select the disk_used_percent metric.
Set the threshold to 80% and configure the alarm actions (e.g., sending a notification).

質問 # 502
A company is running distributed computing software to manage a fleet of 20 Amazon EC2 instances for calculations. The fleet includes 2 control nodes and 18 task nodes to run the calculations. Control nodes can automatically start the task nodes.
Currently, all the nodes run on demand. The control nodes must be available 24 hours a day, 7 days a week.
The task nodes run for 4 hours each day. A SysOps administrator needs to optimize the cost of this solution.
Which combination of actions will meet these requirements? (Choose two.)

A. Purchase EC2 Instance Savings Plans for the control nodes.
B. Use Spot Instances for the control nodes. Use On-Demand Instances if there is no Spot availability.
C. Use Reserved Instances for the task nodes.
D. Use Spot Instances for the task nodes. Use On-Demand Instances if there is no Spot availability.
E. Use Dedicated Hosts for the control nodes.

正解：A、D

解説：
To optimize the cost of a computing environment consisting of control nodes that are always on and task nodes that operate for a limited number of hours each day, consider the following strategies:
* Purchase EC2 Instance Savings Plans for the Control Nodes: Since the control nodes are required to be operational 24/7, purchasing EC2 Instance Savings Plans is a cost-effective choice. These plans provide a lower price compared to on-demand instances, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a one or three-year period.
* Use Spot Instances for the Task Nodes: Given that task nodes are used for a shorter duration (4 hours a day) and presumably can tolerate interruptions, using Spot Instances can significantly reduce costs.
Spot Instances offer unused EC2 capacity at a fraction of the regular price, which can lead to substantial cost savings. Additionally, configure the system to fall back to On-Demand Instances during periods when Spot Instances are not available to ensure availability.
This combination leverages cost savings for continuous use and flexible, lower-cost options for intermittent use, optimizing overall operational costs efficiently.

質問 # 503
A non-production application is installed on an Amazon EC2 instance. The application's developer has created an Amazon CloudWatch alarm that reboots the EC2 instance if a critical application error occurs.
When the developer tests the new alarm, the alarm enters ALARM state. However, the EC2 instance fails to reboot. A SysOps administrator needs to troubleshoot the developer's IAM permissions. What should the SysOps administrator do to ensure that the developer can configure the alarm correctly?

A. Ensure that the developer has the iam:CreateServiceSpecificCredential permission.
B. Ensure that the developer has the iamiCreateServiceLinkedRole permission.
C. Ensure that the developer has the iam:AttachGroupPolicy permission.
D. Ensure that the developer does not have the iam:EnabieMFADevice permission.

正解：B

解説：
CloudWatch alarm actions like EC2 reboot require CloudWatch to assume a service-linked role to interact with EC2 on behalf of the user.
From the Amazon CloudWatch documentation:
When you create an alarm that performs actions such as rebooting an instance, CloudWatch uses a service- linked role named AWSServiceRoleForCloudWatchEvents to execute the action.
To create this role, a user must have the iam:CreateServiceLinkedRole permission.

質問 # 504
A SysOps administrator is setting up an automated process to recover an Amazon EC2 instance In the event of an underlying hardware failure. The recovered instance must have the same private IP address and the same Elastic IP address that the original instance had. The SysOps team must receive an email notification when the recovery process is initiated.
Which solution will meet these requirements?

A. Create an Auto Scaling group across three different subnets in the same Availability Zone with a minimum, maximum, and desired size of 1. Configure the Auto Seating group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to send an email message to the SysOps team through Amazon Simple Email Service (Amazon SES).
B. Create an Amazon CloudWatch alarm for the EC2 Instance, and specify the StatusCheckFailed_System metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.
C. Create an Amazon CloudWatch alarm for the EC2 instance, and specify the SiatusCheckFailedjnstance metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS> topic. Subscribe the SysOps team email address to the SNS topic.
D. Create an Auto Scaling group across three Availability Zones with a minimum, maximum, and desired size of 1. Configure the Auto Scaling group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.

正解：B

解説：
Reference:
You can create an Amazon CloudWatch alarm that monitors an Amazon EC2 instance and automatically recovers the instance if it becomes impaired due to an underlying hardware failure or a problem that requires AWS involvement to repair. Terminated instances cannot be recovered. A recovered instance is identical to the original instance, including the instance ID, private IP addresses, Elastic IP addresses, and all instance metadata. If the impaired instance has a public IPv4 address, the instance retains the public IPv4 address after recovery. If the impaired instance is in a placement group, the recovered instance runs in the placement group. When the StatusCheckFailed_System alarm is triggered, and the recover action is initiated, you will be notified by the Amazon SNS topic that you selected when you created the alarm and associated the recover action. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-recover.html
