What does elasticity mean to AWS?

A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years. The company’s business has grown rapidly in the past few months. In response the company’s operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.

The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances. Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)

A solutions architect must analyze a company’s Amazon EC2 instances and Amazon Elastic Block Store (Amazon EBS) volumes to determine whether the company is using resources efficiently. The company is running several large, highmemory EC2 instances to host database clusters that are deployed in active/passive configurations. The utilization of these EC2 instances varies by the applications that use the databases, and the company has not identified a pattern. The solutions architect must analyze the environment and take action based on the findings.

Which solution meets these requirements MOST cost-effectively?

A company is using an on-premises Active Directory service for user authentication. The company wants to use the same authentication service to sign in to the company’s AWS accounts, which are using AWS Organizations. AWS Site-to- Site VPN connectivity already exists between the on-premises environment and all the company’s AWS accounts. The company’s security policy requires conditional access to the accounts based on user groups and roles. User identities must be managed in a single location. Which solution will meet these requirements?

After your Lambda function has been running for some time, you need to look at some metrics to ascertain how your function is performing and decide to use the AWS CLI to do this. Which of the following commands must be used to access these metrics using the AWS CLI?

A company built an ecommerce website on AWS using a three-tier web architecture. The application is Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.

Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts.

The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics.

Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis. Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events? (Choose three.)

When using Numeric Conditions within IAM, short versions of the available comparators can be used instead of the more verbose versions. Which of the following is the short version of the Numeric Condition "NumericLessThanEquals"?

A company wants to move a web application to AWS. The application stores session information locally on each web server, which will make auto scaling difficult. As part of the migration, the application will be rewritten to decouple the session data from the web servers. The company requires low latency, scalability, and availability.

Which service will meet the requirements for storing the session information in the MOST cost-effective way?
