A company is running Amazon EC2 On-Demand Instances in an Auto Scaling group. The instances process messages from an Amazon Simple Queue Service (Amazon SQS) queue. The Auto Scaling group is set to scale based on the number of messages in the queue. Messages can take up to 12 hours to process completely. A SysOps administrator must ensure that instances are not interrupted during message processing. What should the SysOps administrator do to meet these requirements?
A. Enable instance scale-in protection for the specific instance in the Auto Scaling group atthe start of message processing by calling the Amazon EC2 Auto Scaling API from theprocessing script. Disable instance scale-in protection after message processing iscomplete by calling the Amazon EC2 Auto Scaling API from the processing script.
B. Set the Auto Scaling group's termination policy to OldestInstance.
C. Set the Auto Scaling group's termination policy to OldestLaunchConfiguration.
D. Suspend the Launch and Terminate scaling processes for the specific instance in theAuto Scaling group at the start of message processing by calling the Amazon EC2 AutoScaling API from the processing script. Resume the scaling processes after messageprocessing is complete by calling the Amazon EC2 Auto Scaling API from the processingscript.
A company deployed a new web application on multiple Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run in an Auto Scaling group. Users report that they are frequently being prompted to log in. What should a SysOps administrator do to resolve this issue?
A. Configure an Amazon CloudFront distribution with the ALB as the origin.
B. Enable sticky sessions (session affinity) for the target group of EC2 instances.
C. Redeploy the EC2 instances in a spread placement group.
D. Replace the ALB with a Network Load Balancer.
A company is implementing a monitoring solution that is based on machine learning. The monitoring solution consumes Amazon EventBridge (Amazon CloudWatch Events) events that are generated by Amazon EC2 Auto Scaling. The monitoring solution provides detection of anomalous behavior such as unanticipated scaling events and is configured as an EventBridge (CloudWatch Events) API destination. During initial testing, the company discovers that the monitoring solution is not receiving events. However, Amazon CloudWatch is showing that the EventBridge (CloudWatch Events) rule is being invoked. A SysOps administrator must implement a solution to retrieve client error details to help resolve this issue. Which solution will meet these requirements with the LEAST operational effort?
A. Create an EventBridge (CloudWatch Events) archive for the event pattern to replay theevents. Increase the logging on the monitoring solution. Use replay to invoke themonitoring solution. Examine the error details.
B. Add an Amazon Simple Queue Service (Amazon SQS) standard queue as a dead-letterqueue for the target. Process the messages in the dead-letter queue to retrieve errordetails.
C. Create a second EventBridge (CloudWatch Events) rule for the same event pattern totarget an AWS Lambda function. Configure the Lambda function to invoke the monitoringsolution and to record the results to Amazon CloudWatch Logs. Examine the errors in thelogs.
D. Configure the EventBridge (CloudWatch Events) rule to send error messages to anAmazon Simple Notification Service (Amazon SNS) topic.
A company is using an Amazon EC2 Auto Scaling group to support a workload A Sytfhe company now needs to centruito Scaling group is configured with two similar scaling policies dP) to centrally manage access to One scaling policy adds 5 instances when CPU utilization reaches 80%. The other sctrator can connect to the extemahen CPU utilization leaches 80%. What will happen when CPU utilization reaches the 80% threshold?
A. Amazon EC2 Auto Scaling will add 5 instances
B. Amazon EC2 Auto Scaling will add 10 instances
C. Amazon EC2 Auto Scaling will add 15 instances.
D. The Auto Scaling group will not scale because of conflicting policies
A global company operates out of five AWS Regions. A SysOps administrator wants to identify all the company's tagged and untagged Amazon EC2 instance The company requires the output to display the instance ID and tags. What is the MOST operationally efficient way for the SysOps administrator to meet these requirements?
A. Create a tag-based resource group in AWS Resource Groups.
B. Use AWS Trusted Advisor. Export the EC2 On-Demand Instances check results from Trusted Advisor.
C. Use Cost Explorer. Choose a service type of EC2-Instances, and group by Resource.
D. Use Tag Editor in AWS Resource Groups. Select all Regions, and choose a resourcetype of AWS::EC2::Instance.
A Sysops administrator configured AWS Backup to capture snapshots from a single Amazon EC2 instance that has one Amazon Elastic Block Store (Amazon EBS) volume attached. On the first snapshot, the EBS volume has 10 GiB of data. On the second snapshot, the EBS volume still contains 10 GiB of data, but 4 GiB have changed. On the third snapshot, 2 GiB of data have been added to the volume, for a total of 12 GiB. How much total storage is required to store these snapshots?
A. 12 GiB
B. 16 GiB
C. 26 GiB
D. 32 GiB
A SysOps administrator has set up a new Amazon EC2 instance as a web server in a public subnet. The instance uses HTTP port 80 and HTTPS port 443. The SysOps administrator has confirmed internet connectivity by downloading operating system updates and software from public repositories. However, the SysOps administrator cannot access the instance from a web browser on the internet. Which combination of steps should the SysOps administrator take to troubleshoot this issue? (Select THREE.)
A. Ensure that the inbound rules of the instance's security group allow traffic on ports 80 and 443.
B. Ensure that the outbound rules of the instance's security group allow traffic on ports 80 and 443.
C. Ensure that ephemeral ports 1024-65535 are allowed in the inbound rules of thenetwork ACL that is associated with the instance's subnet.
D. Ensure that ephemeral ports 1024-65535 are allowed in the outbound rules of thenetwork ACL that is associated with the instance's subnet.
E. Ensure that the filtering rules for any firewalls that are running on the instance allowinbound traffic on ports 80 and 443.
F. Ensure that AWS WAF is turned on for the instance and is blocking web traffic.
A SysOps administrator needs to ensure that an Amazon RDS for PostgreSQL DB instance has available backups The DB instance has automated backups turned on with a backup retention period of 7 days. However, no automated backups for the DB instance have been created in the past month. What could be the cause of the lack of automated backups?
A. The Amazon S3 bucket that stores the backups is full
B. The DB instance is in the STORAGE_FULL state
C. The DB instance is not configured for Multi-AZ.
D. The backup retention period must be 30 days.
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. Create an 1AM role that includes the Cloud Watch AgentServerPol icy AWS managedpolicy Attach me role to the instances
B. Create an 1AM role that includes the CloudWatchApplicationInsightsReadOnlyAccessAWS managed policy. Attach the role to the instances
C. Install and start the CloudWatch agent by using AWS Systems Manager or thecommand line
