Question 335:
A SysOps administrator needs to implement a backup strategy for Amazon EC2 resources and Amazon RDS resources. The backup strategy must meet the following retention requirements:
1.
Daily backups: must be kept for 6 days
2.
Weekly backups: must be kept for 4 weeks:
3.
Monthly backups: must be kept for 11 months
4.
Yearly backups: must be kept for 7 years
Which backup strategy will meet these requirements with the LEAST administrative effort?
A. Use Amazon Data Lifecycle Manager to create an Amazon Elastic Block Store (Amazon EBS) snapshot policy. Create tags on each resource that needs to be backed up. Create multiple schedules according to the requirements within the policy. Set the appropriate frequency and retention period. B. Use AWS Backup to create a new backup plan for each retention requirement with a backup frequency of daily, weekly, monthly, or yearly. Set the retention period to match the requirement. Create tags on each resource that needs to be backed up. Set up resource assignment by using the tags. C. Create an AWS Lambda function. Program the Lambda function to use native tooling to take backups of file systems in Amazon EC2 and to make copies of databases in Amazon RDS. Create an Amazon EventBridge rule to invoke the Lambda function. D. Use Amazon Data Lifecycle Manager to create an Amazon Elastic Block Store (Amazon EBS) snapshot policy. Create tags on each resource that needs to be backed up. Set up resource assignment by using the tags. Create multiple schedules according to the requirements within the policy. Set the appropriate frequency and retention period. In Amazon RDS, activate automated backups on the required DB instances.
B. Use AWS Backup to create a new backup plan for each retention requirement with a backup frequency of daily, weekly, monthly, or yearly. Set the retention period to match the requirement. Create tags on each resource that needs to be backed up. Set up resource assignment by using the tags. Has to be AWS Backup since "EBS snapshot" isn't mentioned in requirements. "Use Amazon Data Lifecycle Manager when you want to automate the creation, retention, and deletion of EBS snapshots. Use AWS Backup to manage and monitor backups across the AWS services you use, including EBS volumes, from a single plac" https://aws.amazon.com/backup/faqs/
Question 336:
A company has a stateless application that runs on four Amazon EC2 instances. The application requires tour instances at all times to support all traffic. A SysOps administrator must design a highly available, fault-tolerant architecture that continually supports all traffic if one Availability Zone becomes unavailable.
Which configuration meets these requirements?
A. Deploy two Auto Scaling groups in two Availability Zones with a minimum capacity of two instances in each group. B. Deploy an Auto Scaling group across two Availability Zones with a minimum capacity of four instances. C. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of four instances. D. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of six instances.
C. Deploy an Auto Scaling group across three Availability Zones with a minimum capacity of four instances.
Question 337:
A company has an Amazon EC2 instance that has high CPU utilization. The EC2 instance is a t3.large instance and is running a test web application. The company discovers that the web application would operate better on a compute optimized large instance.
