Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q147-Q152):
NEW QUESTION # 147
A DevOps Engineer administers an application that manages video files for a video production company. The application runs on Amazon EC2 instances behind an ELB Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. Data is stored in an Amazon RDS PostgreSOL Multi-AZ DB instance, and the video ides are stored in an Amazon S3 bucket. On a typical day 50 GB of new video are added to the S3 bucket. The Engineer must implement a multi-region disaster recovery plan with the least data loss and the lowest recovery times. The current application infrastructure is already described using AWS CloudFormation.
Which deployment option should the Engineer choose to meet the uptime and recovery objectives for the system?
- A. Launch the application from the CloudFormation template in the second region which sets the capacity of the Auto Scaling group to 1. Use Amazon CloudWatch Events to schedule a nightly task to take a snapshot of the database, copy the snapshot to the second region, and replace the DB instance in the second region from the snapshot. In the second region, enable cross-region replication between the original S3 bucket and a new S3 bucket. To fail over, increase the capacity of the Auto Scaling group.
- B. Launch the application from the CloudFormation template in the second region, which sets the capacity of the Auto Scaling group to 1. Create an Amazon RDS read replica in the second region. In the second region, enable cross-region replication between the original S3 bucket and a new S3 bucket. To fail over, promote the read replica as master. Update the CloudFormation stack and increase the capacity of the Auto Scaling group.
- C. Launch the application from the CloudFormation template in the second region, witch sets the capacity of the Auto Scaling group to 1. Create a scheduled task to take daily Amazon RDS cross-region snapshots to the second region. In the second region, enable cross-region replication between the original S3 bucket and Amazon Glacier. In a disaster, launch a new application stack in the second region and restore the database from the most recent snapshot.
- D. Use Amazon CloudWatch Events to schedule a nightly task to take a snapshot of the database and copy the snapshot to the second region. Create an AWS Lambda function that copies each object to a new S3 bucket in the second region in response to S3 event notifications. In the second region, launch the application from the CloudFormation template and restore the database from the most recent snapshot.
Answer: A
NEW QUESTION # 148

NEW QUESTION # 150
You use Amazon Cloud Watch as your primary monitoring system for your web application. After a recent software deployment, your users are getting Intermittent 500 Internal Server Errors when using the web application. You want to create a Cloud Watch alarm, and notify an on-call engineer when these occur. How can you accomplish this using AWS services? Choose three answers from the options given below
- A. Use Amazon Simple Email Service to notify an on-call engineer when a CloudWatch alarm is triggered.
- B. Install a CloudWatch Logs Agent on your servers to stream web application logs to CloudWatch.
- C. Create a CloudWatch Logs group and define metric filters that capture 500 Internal Server Errors. Set a CloudWatch alarm on that metric.
- D. Deploy your web application as an AWS Elastic Beanstalk application. Use the default Elastic Beanstalk Cloudwatch metrics to capture 500 Internal Server Errors. Set a CloudWatch alarm on that metric.
- E. Use Amazon Simple Notification Service to notify an on-call engineer when a CloudWatch alarm is triggered.
Answer: B,C,E
Explanation:
Explanation
You can use Cloud Watch Logs to monitor applications and systems using log data Cloud Watch Logs uses your log data for monitoring; so, no code changes are required. For example, you can monitor application logs for specific literal terms (such as "NullReferenceCxception") or count the number of occurrences of a literal term at a particular position in log data (such as "404" status codes in an Apache access log). When the term you are searching for is found. Cloud Watch Logs reports the data to a CloudWatch metric that you specify. Log data is encrypted while in transit and while it is at rest For more information on Cloudwatch logs please refer to the below link:
