| Question.91 A company runs an application that uses a MySQL database on an Amazon EC2 instance. The EC2 instance has a General Purpose SSD Amazon Elastic Block Store (Amazon EBS) volume. The company made changes to the application code and now wants to perform load testing to evaluate the impact of the code changes. A SysOps administrator must create a new MySQL instance from a snapshot of the existing production instance. This new instance needs to perform as similarly as possible to the production instance. Which restore option meets these requirements? (A) Use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot. (B) Use EBS fast snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot. (C) Use EBS snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot. (D) Use EBS snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot. |

| Question.92 A company has an application that customers use to search for records on a website. The application’s data is stored in an Amazon Aurora DB cluster. The application’s usage varies by season and by day of the week. The website’s popularity is increasing, and the website is experiencing slower performance because of increased load on the DB cluster during periods of peak activity. The application logs show that the performance issues occur when users are searching for information. The same search is rarely performed multiple times. A SysOps administrator must improve the performance of the platform by using a solution that maximizes resource efficiency. Which solution will meet these requirements? (A) Deploy an Amazon ElastiCache for Redis cluster in front of the DB cluster. Modify the application to check the cache before the application issues new queries to the database. Add the results of any queries to the cache. (B) Deploy an Aurora Replica for the DB cluster. Modify the application to use the reader endpoint for search operations. Use Aurora Auto Scaling to scale the number of replicas based on load. (C) Use Provisioned IOPS on the storage volumes that support the DB cluster to improve performance sufficiently to support the peak load on the application. (D) Increase the instance size in the DB cluster to a size that is sufficient to support the peak load on the application. Use Aurora Auto Scaling to scale the instance size based on load. |

| Question.93 A company recently purchased Savings Plans. The company wants to receive email notification when the companys utilization drops below 90% for a given day. Which solution will meet this requirement? (A) Create an Amazon CloudWatch alarm to monitor the Savings Plan check in AWS Trusted Advisor. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification when the utilization drops below 90% for a given day. (B) Create an Amazon CloudWatch alarm to monitor the SavingsPlansUtilization metric under the AWS/SavingsPlans namespace in CloudWatch. Configure an Amazon Simple Queue Service (Amazon SQS) queue for email notification when the utilization drops below 90% for a given day. (C) Create a Savings Plans alert to monitor the daily utilization of the Savings Plans. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification when the utilization drops below 90% for a given day. (D) Use AWS Budgets to create a Savings Plans budget to track the daily utilization of the Savings Plans. Configure an Amazon Simple Notification Service (Amazon SNS) topic for email notification when the utilization drops below 90% for a given day. |

| Question.94 An ecommerce company uses an Amazon ElastiCache for Memcached cluster for in-memory caching of popular product queries on the shopping site. When viewing recent Amazon CloudWatch metrics data for the ElastiCache cluster, the SysOps administrator notices a large number of evictions. Which of the following actions will reduce these evictions? (Choose two.) (A) Add an additional node to the ElastiCache cluster. (B) Increase the ElastiCache time to live (TTL). (C) Increase the individual node size inside the ElastiCache cluster. (D) Put an Elastic Load Balancer in front of the ElastiCache cluster. (E) Use Amazon Simple Queue Service (Amazon SQS) to decouple the ElastiCache cluster. |

| Question.95 A company has an existing public web application for www.example.com. The Application Load Balancer (ALB) is configured with a single HTTP 80 listener. A SysOps administrator must ensure that all web requests to www.example.com are encrypted between the client and the ALB. The SysOps administrator already has requested and validated a public certificate for www.example.com in AWS Certificate Manager (ACM). Existing users of the application must not be required to change the endpoint to which they are connecting. Which additional set of steps should the SysOps administrator take to meet these requirements? (A) Create an additional ALB listener for HTTPS on port 443. Set the default action to forward all traffic to the target group. Specify the ACM certificate that was created for www.example.com as the default SSL certificate. (B) Create an additional ALB listener for HTTPS on port 443. Set the default action to forward all traffic to the target group. Specify the ACM certificate that was created for www.example.com as the default SSL certificate. Delete the original HTTP listener on port 80. (C) Modify the ALB default rule for the HTTP port 80 listener. Create a rule in the listener to forward all traffic for the host www example.com to the target group. Specify the ACM certificate that was created for www.example.com as the default SSL certificate. (D) Modify the ALB default rule for the HTTP port 80 listener to redirect to HTTPS on port 443. Create an additional HTTPS listener on port 443. Set the default action to forward all traffic to the target group. Specify the ACM certificate that was created for www example.com as the default SSL certificate. |
