Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q457-Q462):

NEW QUESTION # 457
A DevOps Engineer needs to deploy a scalable three-tier Node.js application in AWS. The application must have zero downtime during deployments and be able to roll back to previous versions. Other applications will also connect to the same MySQL backend database. The CIO has provided the following guidance for logging:
- Centrally view all current web access server logs.
- Search and filter web and application logs in near-real time.
- Retain log data for three months.
How should these requirements be met?

  • A. Deploy the application on Amazon EC2. Configure Elastic Load Balancing and Auto Scaling. Use an Amazon RDS MySQL instance for the database tier. Configure the application to store log files in Amazon S3. Use Amazon EMR to search and filter the data. Set an Amazon S3 lifecycle rule to expire objects after 90 days.
  • B. Deploy the application using AWS Elastic Beanstalk. Configure the environment type for Elastic Load Balancing and Auto Scaling. Create the Amazon RDS MySQL instance outside the Elastic Beanstalk stack. Configure the Elastic Beanstalk log options to stream logs to Amazon CloudWatch Logs. Set retention to 90 days.
  • C. Deploy the application using AWS Elastic Beanstalk. Configure the environment type for Elastic Load Balancing and Auto Scaling. Create an Amazon RDS MySQL instance inside the Elastic Beanstalk stack. Configure the Elastic Beanstalk log options to stream logs to Amazon CloudWatch Logs. Set retention to 90 days.
  • D. Deploy the application on Amazon EC2. Configure Elastic Load Balancing and Auto Scaling. Use an Amazon RDS MySQL instance for the database tier. Configure the application to load streaming log data using Amazon Kinesis Data Firehouse into Amazon ES. Delete and create a new Amazon ES domain every 90 days.

Answer: B

Explanation:
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.logging.html The Amazon EC2 instances in your Elastic Beanstalk environment generate logs that you can view to troubleshoot issues with your application or configuration files. Logs created by the web server, application server, Elastic Beanstalk platform scripts, and AWS CloudFormation are stored locally on individual instances. You can easily retrieve them by using the environment management console or the EB CLI. You can also configure your environment to stream logs to Amazon CloudWatch Logs in real-time.

NEW QUESTION # 459
A DevOps Engineer is working with an application deployed to 12 Amazon EC2 instances across 3 Availability Zones. New instances can be started from an AMI image. On a typical day, each EC2 instance has
30% utilization during business hours and 10% utilization after business hours. The CPU utilization has an immediate spike in the first few minutes of business hours. Other increases in CPU utilization rise gradually.
The Engineer has been asked to reduce costs while retaining the same or higher reliability.
Which solution meets these requirements?

  • A. Create two Amazon CloudWatch Events rules with schedules before and after business hours begin and end. Create an AWS CloudFormation stack, which creates an EC2 Auto Scaling group, with a parameter for the number of instances. Invoke the stack from each rule, passing a parameter value of three in the morning, and six in the evening.
  • B. Create an EC2 Auto Scaling group using the AMI image, with a scaling action based on the Auto Scaling group's CPU Utilization average with a target of 75%. Create a scheduled action to terminate nine instances each evening after the close of business.
  • C. Create two Amazon CloudWatch Events rules with schedules before and after business hours begin and end. Create two AWS Lambda functions, one invoked by each rule. The first function should stop nine instances after business hours end, the second function should restart the nine instances before the business day begins.
  • D. Create an Amazon EC2 Auto Scaling group using the AMI image, with a scaling action based on the Auto Scaling group's CPU Utilization average with a target of 75%. Create a scheduled action for the group to adjust the minimum number of instances to three after business hours end and reset to six before business hours begin.

Answer: C


NEW QUESTION # 460
You are responsible for a large-scale video transcoding system that operates with an Auto Scaling group of video transcoding workers.
The Auto Scaling group is configured with a minimum of 750 Amazon EC2 instances and a maximum of 1000 Amazon EC2 instances.
You are using Amazon SQS to pass a message containing the URI for a video stored in Amazon S3 to the transcoding workers.
An Amazon CloudWatch alarm has notified you that the queue depth is becoming very large.
How can you resolve the alarm without the risk of increasing the time to transcode videos?
Choose 2 answers.

  • A. Add an additional Availability Zone to the Auto Scaling group configuration.
  • B. Create a new Auto Scaling group with a launch configuration that has a larger Amazon EC2 instance type
  • C. Create a second queue in Amazon SQS.
  • D. Adjust the Auto Scaling group configuration to increase the maximum number of Amazon EC2 instances.
  • E. Change the Amazon CloudWatch alarm so that it monitors the CPU utilization of the Amazon EC2 instances rather than the Amazon SQS queue depth.
  • F. Adjust the Amazon CloudWatch alarms for a higher queue depth.

Answer: B,D


NEW QUESTION # 461
You have just recently deployed an application on EC2 instances behind an ELB. After a couple of weeks, customers are complaining on receiving errors from the application. You want to diagnose the errors and are trying to get errors from the ELB access logs. But the ELB access logs are empty. What is the reason for this.

  • A. Access logging is an optional feature of Elastic Load Balancing that is disabled by default
  • B. ELB Access logs are only available for a maximum of one week
  • C. You do not have your CloudWatch metrics correctly configured
  • D. You do not have the appropriate permissions to access the logs

Answer: A

Explanation:
Clastic Load Balancing provides access logs that capture detailed information about requests sent to your load balancer. Cach log contains information such as the time the request was received, the client's IP address, latencies, request paths, and server responses. You can use these access logs to analyze traffic patterns and to troubleshoot issues. Access logging is an optional feature of Elastic Load Balancing that is disabled by default.
