• Question 1421:

  What are characteristics of Availability Zones? (Choose two.)

  A. All Availability Zones in an AWS Region are interconnected with high-bandwidth, low-latency networking.
  B. Availability Zones are physically separated by a minimum of distance of 150 km (100 miles).
  C. All traffic between Availability Zones is encrypted.
  D. Availability Zones within an AWS Region share redundant power, networking, and connectivity.
  E. Every Availability Zone contains a single data center.
  A. All Availability Zones in an AWS Region are interconnected with high-bandwidth, low-latency networking.
  D. Availability Zones within an AWS Region share redundant power, networking, and connectivity.

  Explanation/Reference:

  The characteristics of Availability Zones are:

  A. All Availability Zones in an AWS Region are interconnected with high-bandwidth, low-latency networking.

  D. Availability Zones within an AWS Region share redundant power, networking, and connectivity.

  Option A is true. All Availability Zones in an AWS Region are interconnected with high-bandwidth, low- latency networking. This enables customers to design and deploy highly available and fault-tolerant applications across multiple

  Availability Zones.

  Option D is true. Availability Zones within an AWS Region share redundant power, networking, and connectivity, which increases their availability and fault tolerance.

• Question 1422:

  A user is building a simple online calculator and wants to use AWS compute as cost-effectively as possible. The calculator must be highly available for even a small number of users. Where should the code for calculations be hosted?

  A. On an Amazon EC2 Memory Optimized Reserved Instance
  B. On an Amazon EC2 Compute Optimized Reserved Instance
  C. On an Amazon EC2 Compute Optimized Spot Instance
  D. In an AWS Lambda function
  D. In an AWS Lambda function

• Question 1423:

  A developer is writing a new AWS Serverless Application Model (AWS SAM) template with a new AWS Lambda function. The Lambda function runs complex code. The developer wants to test the Lambda function with more CPU power. What should the developer do to meet this requirement?

  A. Increase the runtime engine version
  B. Increase the timeout
  C. Increase the number of Lambda layers
  D. Increase the memory.
  D. Increase the memory.

• Question 1424:

  A company needs to store infrequently used data archives and long-term backups.

  Which AWS service or storage class will meet these requirements MOST cost-effectively?

  A. Amazon FSx for Lustre.
  B. Amazon Elastic Block Store (Amazon EBS)
  C. Amazon Elastic File System (Amazon EFS)
  D. Amazon S3 Glacier Flexible Retrieval
  D. Amazon S3 Glacier Flexible Retrieval

• Question 1425:

  Which of the following inspects AWS environments to find opportunities that can save money for users and also improve system performance?

  A. AWS Cost Explorer
  B. AWS Trusted Advisor
  C. Consolidated billing
  D. Detailed billing
  B. AWS Trusted Advisor

• Question 1426:

  Which of the following is the responsibility of AWS?

  A. Setting up AWS Identity and Access Management (IAM) users and groups
  B. Physically destroying storage media at end of life
  C. Patching guest operating systems
  D. Configuring security settings on Amazon EC2 instances
  B. Physically destroying storage media at end of life

  ---

  Explanation/Reference:

  Media storage devices used to store customer data are classified by AWS as Critical and treated accordingly, as high impact, throughout their life-cycles. AWS has exacting standards on how to install, service, and eventually destroy the devices when they are no longer useful. When a storage device has reached the end of its useful life, AWS decommissions media using techniques detailed in NIST 800-88. Media that stored customer data is not removed from AWS control until it has been securely decommissioned.

• Question 1427:

  How can a user achieve high availability for a web application hosted on AWS?

  A. Use a Classic Load Balancer across multiple AWS Regions
  B. Use an Application Load Balancer across multiple Availability Zones in one AWS Region
  C. Set up automatic scaling and load balancing with another application instance running on premises
  D. Use the AWS Region with the highest number of Availability Zones
  B. Use an Application Load Balancer across multiple Availability Zones in one AWS Region

• Question 1428:

  What are the multiple, isolated locations within an AWS Region that are connected by low-latency networks called?

  A. AWS Direct Connects
  B. Amazon VPCs
  C. Edge locations
  D. Availability Zones
  D. Availability Zones

  ---

  Explanation/Reference:

  Each Region is completely independent. Each Availability Zone is isolated, but the Availability Zones in a Region are connected through low-latency links. A Local Zone is an AWS infrastructure deployment that places select services closer to your end users. A Local Zone is an extension of a Region that is in a different location from your Region. It provides a high-bandwidth backbone to the AWS infrastructure and is ideal for latency-sensitive applications, for example machine learning.

  A. Amazon EBS
  B. Amazon EFS
  C. Amazon S3
  D. AWS Artifact
  B. Amazon EFS
