AWS Certified SysOps Administrator – Associate Set4

Welcome to AWS Certified SysOps Administrator - Associate Set4.

 

1. Which feature of Systems Manager can you use to run a script on multiple EC2 instances simultaneously and without logging in to each one?
2. You have a web application that uses AutoScaling and Elastic Load Balancing. You want to monitor the application to make sure that it maintains a "good" customer experience, defined in terms of the amount of time it takes to load the application for the end-user in their browser. Which AWS CloudWatch metric can best be used for this?
3. Which of the following ELB error codes indicates a successful request?
4. Which of the following ELB error codes indicates a server-side issue?
5. You are a SysOps Administrator for an events company that is launching a new TV show tomorrow. You are expecting that traffic to your website tomorrow will be huge. You have created an autoscaling group and have a combination of Reserved and On-demand instances ready. You are about to contact AWS support to ask them to prewarm your ELB in order to meet this demand. Typically, AWS requires 3 pieces of information. Which of the following is NOT information that AWS requires?
6. You are supporting a data processing application which runs on an EC2 instance, using gp2 storage and currently performs around 10,000 reads / writes per second. Your Sales and Marketing Teams are planning to introduce a number of additional reports which are expected to at least double the current workload for your application. How can you ensure that the performance of your application does not suffer when the new reports are introduced?
7. You are running your production database in MySQL on an independent EBS volume and you are fast approaching an average IOPS of 9,000. You have decided to migrate your database to an EBS volume with provisioned IOPS. Your key users only use the database between 9 am - 6 pm, so you can afford to have some down time out of hours, but not during the working day. Which is the best option below to achieve this migration.
8. You are deploying a latency sensitive application using EC2 instances. You would like to ensure that all instances are placed in the same AZ for maximum throughput between the components of your application. Which of the following approaches do you recommend?
9. Which of the following ELB error codes indicates a client-side issue?
10. You are a SysOps Administrator at a fast-growing startup that has scripted most of their infrastructure. You have a fleet of EC2 instances behind an elastic load balancer. When a new instance is launched, it performs a number of system updates before automatically copying the website's code from an S3 bucket. Due to the number of steps taken when launching a new instance, it can sometimes take up to 5 minutes for the new instance to be a fully functioning web server. This length of time is now causing a problem, as the Elastic Load Balancer reports the new instance to be unhealthy, and your autoscaling group then deletes it before it can become live. What should you do to prevent this from happening again?
11. Which of the following statements does NOT describe a Bastion host?
12. You are planning to deploy a production database to EC2 and need to choose the best storage type. You anticipate that you will need a maximum of 20,000 IOPS during peak times, but an average of 8,000 - 10,000 IOPS. What storage medium should you choose?
13. You have a fleet of EC2 instances in a private subnet and you need to securely access these via SSH. What should you implement?
14. You would like to receive an alert if more than 3 of your application servers fail to respond to a basic health check by the Elastic Load Balancer. Which metric could you use to configure this?
15. What does the term PIOPS stand for when dealing with EBS?
16. Your web application runs on a group EC2 instances behind a Classic Load Balancer. This morning, users are complaining that the application is running very slowly. You suspect this is due to a significant increase in traffic to your application. Which CloudWatch metrics could you use, to determine if you are correct? (Choose 2)
17. Your new question!
18. By default, how frequently are ELB metrics published to CloudWatch?
19. Which service does Systems Manager integrate with to give you visibility of the overall health of your AWS infrastructure?
20. You are running an application on a load-balanced group of 10 EC2 instances. Which of the following metrics would use to check how many of your application servers are available?
21. You are about to initiate a load test on your website to ensure it can keep up with seasonal demands. Your website is behind an elastic load balancer and will receive a burst of traffic totalling of millions of requests. What should you do to prepare for this?
22. You are a SysOps engineer at a startup that is growing quite quickly. The startup has a fleet of EC2 instances inside an autoscaling group that scales based on CPU Utilization. You notice that CPU Utilization is not a good metric, and that the main bottleneck is the maxed-out number of connections between the ELB and an EC2 instance. You want to adjust your Autoscaling configuration to address this bottleneck. Which two of the following ELB metrics should you consider?
23. What is the maximum IOPS capability of a gp2 volume?
24. What is the maximum IOPS capability of an io1 volume?
25. Which of the following management tools gives you visibility and operational control over your AWS infrastructure?
26. You are attempting to launch a number of on-demand EC2 instances, but the launch operation fails with an InsufficientInstanceCapacity error. What does this error mean?
27. You need to configure a load balancer with a static IP address, which of the following would you recommend?
28. You are attempting to launch a number of on-demand EC2 instances, but the launch operation fails with the InstanceLimitExceeded error. What does this error mean?
29. Which of the following is most suitable for load balancing requests to latency sensitive production applications?
30. Which of the following is most suitable for load balancing based on the content of HTTP / HTTPS request headers?
