A company runs us Infrastructure on Amazon EC2 Instances that run In an Auto Scaling group.
Recently, the company promoted faulty code to the entire EC2 fleet. This faulty code caused the Auto Scaling group to scale the instances before any of the application logs could be retrieved.
What should a SysOps administrator do to retain the application logs after instances are terminated?

• A.Install the Amazon CloudWatch agent on the Amazon Machine Image (AMI) that is defined in the launch template. Configure the CloudWatch agent to back up the logs to ephemeral storage.
• B.Configure an Auto Scaling lifecycle hook to create a snapshot of the ephemeral storage upon termination of the instances.
• C.Create a new Amazon Machine Image (AMI) that has a custom script configured to send logs to AWS CloudTrail. Update the launch template to use the new AMI.
• D.Create a new Amazon Machine Image (AMI) that has the Amazon CloudWatch agent installed and configured to send logs to Amazon CloudWatch Logs. Update the launch template to use the new AMI.

A company is running a website on Amazon EC2 instances behind an Application Load Balancer (ALB). The company configured an Amazon CloudFront distribution and set the ALB as the origin. The company created an Amazon Route 53 CNAME record to send all traffic through the CloudFront distribution. As an unintended side effect, mobile users are now being served the desktop version of the website.
Which action should a SysOps administrator take to resolve this issue?

• A.Configure the CloudFront distribution behavior to forward the User-Agent header.
• B.Configure the CloudFront distribution origin settings. Add a User-Agent header to the list of origin custom headers.
• C.Enable IPv6 on the ALB. Update the CloudFront distribution origin settings to use the dualstack endpoint.
• D.Enable IPv6 on the CloudFront distribution. Update the Route 53 record to use the dualstack endpoint.

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?

• A.Add additional t2.large instances to the application.
• B.Upgrade to a compute-optimized instance.
• C.Purchase Reserved Instances
• D.Change the Amazon EBS volume to Provisioned IOPs.

A Systems Administrator is planning to deploy multiple EC2 instances within two separate Availability Zones in the same AwS Region.
The instances cannot be exposed to the Internet, but must be able to exchange traffic between one another. The data does not need to be encrypted.
What solution meets these requirements while maintaining the lowest cost?

• A.Create two private subnets within the same VPC.
  Communicate between instances using their private IP addresses
• B.Create 2 public subnets within the same VPC.
  Communicate between instances using their public IP addresses
• C.Create 2 separate VPCs, one for each Availability Zone.
  Create a private subnet within each VPC.
  Create a static route table pointing the destination CIDR to the other VPC
• D.Create 2 separate VPCs, one for each Availability Zone and create a public subnet in each.
  Deploy a VPN appliance within each VPC and establish a VPN tunnel between them.
  Communicate between instances by routing traffic through the VPN appliances
