A web application accepts orders from online users and places the orders into an Amazon SQS queue. Amazon EC2 instances in an EC2 Auto Scaling group read the messages from the queue, process the orders, and email order confirmations to the users. The Auto Scaling group scales up and down based on the queue depth. At the beginning of each business day, users report confirmation emails are delayed.
What action will address this issue?

• A.  Change the launch configuration to launch larger EC2 instance types.
• B.  Change the Auto Scaling group to scale up and down based on CPU utilization.
• C.  Modify the scaling policy to deploy more EC2 instances when scaling up.
• D.  Create a scheduled scaling action to scale up in anticipation of the traffic.

A company has adopted a security policy that requires all customer data to be encrypted at rest. Currently, customer data is stored on a central Amazon EFS file system and accessed by a number of different applications from Amazon EC2 instances.
How can the SysOps Administrator ensure that all customer data stored on the EFS file system meets the new requirement?

• A.  Create a new encrypted EFS file system and copy the data from the unencrypted EFS file system to the new encrypted EFS file system.
• B.  Modify the EFS file system mount options to enable Transport Layer Security (TLS) on each of the EC2 instances.
• C.  Update the EFS file system settings to enable server-side encryption using AES-256.
• D.  Use AWS CloudHSM to encrypt the files directly before storing them in the EFS file system.

A SysOps Administrator is receiving alerts related to high CPU utilization of a Memcached-based Amazon ElastiCache cluster.
Which remediation steps should be taken to resolve this issue? (Select TWO.)

• A.  Add a load balancer to route traffic to the ElastiCache cluster
• B.  Add additional worker nodes to the ElastiCache cluster
• C.  Add a larger Amazon EBS volume to the ElastiCache cluster nodes
• D.  Create an Auto Scaling group to the ElastiCache cluster
• E.  Vertically scale the ElastiCache cluster by changing the node type

A medical imaging company needs lo process large amounts of imaging data in real time using a specific instance type. The company wants to guarantee sufficient resource capacity for 1 year Which action will meet these requirements in the MOST cost-effective manner?

• A.  Purchase 1 -year Reserved Instances in the specific Availability Zones
• B.  Launch Amazon EC2 instances with termination protection enabled
• C.  Create 1-year On-Demand Capacity Reservations in the specific Availability Zones
• D.  Use a Spot Fleet across multiple Availability Zones

A company's application infrastructure was deployed using AWS CloudFormation and is composed of Amazon EC2 instances behind an Application Load Balancer. The instances run an EC2 Auto Scaling group across multiple Availability Zones. When releasing a new version of the application, the update deployment must avoid DNS changes and allow rollback.
Which solution should a sysops administrator use to meet the deployment requirements for this new release?

• A.  Modify the CloudFormation template to use an AutoScalingReplacingUpdate policy. Update the stack. Perform a second update with the new release
• B.  Configure the Auto Scaling group to use lifecycle hooks. Deploy now instances with the new application version. Complete the lifecycle hook action once healthy.
• C.  Deploy a second CloudFormation stack. Wait for the application to be available Cut over to the new Application Load Balancer
• D.  Create a new Amazon Machine Image (AMI) containing the updated code. Create a launch configuration with the AMI. Update Auto Scaling group to use the new lauch configuration.
