How to troubleshoot a non-responsive Amazon EC2 instance with failing system checks?

Single Choice

A SysOps administrator is notified that an Amazon EC2 instance has stopped responding. The AWS Management Console indicates that the system checks are failing.

What should the administrator do first to resolve this issue?

Reboot the EC2 instance so it can be launched on a new host.

Stop and then start the EC2 instance so that it can be launched on a new host.

Terminate the EC2 instance and relaunch it.

View the AWS CloudTrail log to investigate what changed on the EC2 instance.

How can a SysOps administrator optimize a workload running in multiple AWS Regions using AWS Lambda and Amazon EC2 On-Demand Instances?

Single Choice

A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users locations.

Which approach should the SysOps administrator use to optimize this workload?

Purchase Compute Savings Plans based on the usage during the past 30 days.

Purchase Convertible Reserved Instances by calculating the usage baseline.

Purchase EC2 Instance Savings Plans based on the usage during the past 30 days.

Purchase Standard Reserved Instances by calculating the usage baseline.

Networking and Content Delivery Cost and Performance Optimization

How can a SysOps administrator provide shared storage with low latency to multiple EC2 instances?

Single Choice

A SysOps administrator is provisioning an Amazon Elastic File System (Amazon EFS) file system to provide shared storage across multiple Amazon EC2 instances. The instances all exist in the same VPC across multiple Availability Zones. There are two instances in each Availability Zone. The SysOps administrator must make the file system accessible to each instance with the lowest possible latency.

Which solution will meet these requirements?

Create a mount target for the EFS file system in the VPC. Use the mount target to mount the file system on each of the instances.

Create a mount target for the EFS file system in one Availability Zone of the VPC. Use the mount target to mount the file system on the instances in that Availability Zone. Share the directory with the other instances.

Create a mount target for each instance. Use each mount target to mount the EFS file system on each respective instance.

Create a mount target in each Availability Zone of the VPC. Use the mount target to mount the EFS file system on the instances in the respective Availability Zone.

How can a SysOps Administrator receive email alerts for low storage space on Amazon EBS volumes?

Single Choice

A SysOps Administrator is required to monitor free space on Amazon EBS volumes attached to Microsoft Windows-based Amazon EC2 instances within a company s account. The administrator must be alerted to potential issues.

What should the administrator do to receive email alerts before low storage space affects EC2 instance performance?

Use built-in Amazon CloudWatch metrics, and configure CloudWatch alarms and an Amazon SNS topic for email notifications.

Use AWS CloudTrail logs and configure the trail to send notifications to an Amazon SNS topic.

Use the Amazon CloudWatch agent to send disk space metrics, then set up CloudWatch alarms using an Amazon SNS topic.

Use AWS Trusted Advisor and enable email notification alerts for EC2 disk space.

Monitoring and Reporting

How can the performance problem of a CPU-heavy application on a single t2.large Amazon EC2 instance be alleviated?

Single Choice

A SysOps administrator is responsible for a legacy, CPU-heavy application. The application can only be scaled vertically. Currently, the application is deployed on a single t2. large Amazon EC2 instance. The system is showing 90% CPU usage and significant performance latency after a few minutes.

What change should be made to alleviate the performance problem?

Change the Amazon EBS volume to Provisioned IOPs.

Upgrade to a compute-optimized instance.

Add additional t2.large instances to the application.

Purchase Reserved Instances

How can a SysOps administrator ensure that users access objects in Amazon S3 only through CloudFront URLs?

Single Choice

A SysOps administrator is reviewing AWS Trusted Advisor warnings and encounters a warning for an S3 bucket policy that has open access permissions. While discussing the issue the bucket owner, the administrator realizes the S3 bucket is an origin for an Amazon CloudFront web distribution.

Which action should the administrator take to ensure that users access objects in Amazon S3 by using only CloudFront URLs?

Encrypt the S3 bucket content with Server-Side Encryption with Amazon S3-Managed Keys (SSE-S3).

Create an origin access identity and grant it permissions to read objects in the S3 bucket.

Assign an IAM user to the CloudFront distribution and grant the user permissions in the S3 bucket policy.

Assign an IAM role to the CloudFront distribution and grant the role permissions in the S3 bucket policy.

How can a SysOps administrator set up an automated process to recover an EC2 instance with the same IP addresses and email notification?

Single Choice

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?

Create an Amazon CloudWatch alarm for the EC2 instance, and specify the StatusCheckFailed_Instance 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.

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.

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 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 send an email message to the SysOps team through Amazon Simple Email Service (Amazon SES).
