• Question 1502:

  Which of the following describes AWS Local Zones?

  A. A cluster of data centers in one geographic location
  B. A site used by Amazon CloudFront to cache frequently accessed content
  C. An extension of an AWS Region to more granular locations
  D. One or more data centers with redundant power and networking
  C. An extension of an AWS Region to more granular locations

  ---

  Explanation/Reference:

  AWS Local Zones are a type of AWS infrastructure deployment that place compute, storage, database, and other select services closer to large population, industry, and IT centers, enabling you to deliver applications that require single-digit millisecond latency to end-users.

• Question 1503:

  Which AWS Cloud benefit eliminates the need for users to try estimating future infrastructure usage?

  A. Easy and fast deployment of applications in multiple Regions around the world
  B. Security of the AWS Cloud
  C. Elasticity of the AWS Cloud
  D. Lower variable costs due to massive economies of scale
  C. Elasticity of the AWS Cloud

• Question 1504:

  A company has a complex AWS architecture. The company needs assistance from a dedicated technical professional who can suggest strategies regarding incidents, trade-offs, support, and risk management. Which AWS Support plan will provide the required support?

  A. AWS Business Support
  B. AWS Enterprise Support
  C. AWS Developer Support
  D. AWS Basic Support
  B. AWS Enterprise Support

  ---

  Explanation/Reference:

  The AWS Support plan that will provide the required support is:

  B. AWS Enterprise Support AWS Enterprise Support provides a dedicated technical account manager (TAM) to help customers achieve their desired outcomes by providing proactive and personalized guidance and support. The TAM is an experienced technical professional who works with customers to understand their business and technical goals, and to provide guidance on AWS services and best practices. The TAM helps customers to optimize their AWS infrastructure, troubleshoot issues, and manage incidents. The TAM also provides support for trade-offs, risk management, and other business decisions related to the customer's use of AWS. With AWS Enterprise Support, customers have access to 24/7 technical support, as well as a range of AWS Trusted Advisor checks and guidance. Customers can also take advantage of AWS Infrastructure Event Management (IEM) to receive proactive notifications about potential issues with their AWS resources.

• Question 1505:

  Which AWS Cloud design principle does a company follow by using AWS CloudTrail?

  A. Recover automatically.
  B. Perform operations as code.
  C. Measure efficiency.
  D. Ensure traceability.
  D. Ensure traceability.

• Question 1506:

  A company needs a quick estimate of the cost to run 100 Amazon EC2 instances with AWS Business Support. Which tool should the company use to generate the estimate?

  A. AWS Budgets
  B. AWS Cost and Usage Report
  C. AWS Pricing Calculator
  D. Cost Explorer
  C. AWS Pricing Calculator

  ---

  Explanation/Reference:

  C. AWS Pricing Calculator. This tool allows the company to input the details of the 100 Amazon EC2 instances and select the AWS Business Support plan to estimate the cost of running those instances. AWS Budgets, AWS Cost and Usage Report, and Cost Explorer provide more detailed information about ongoing costs and usage, rather than a quick estimate.

• Question 1507:

  Which AWS Cloud best practice uses the elasticity and agility of cloud computing?

  A. Provision capacity based on past usage and theoretical peaks
  B. Dynamically and predictively scale to meet usage demands
  C. Build the application and infrastructure in a data center that grants physical access
  D. Break apart the application into loosely coupled components
  B. Dynamically and predictively scale to meet usage demands

  ---

  Explanation/Reference:

  In a traditional computing environment, you provision capacity based on an estimate of a theoretical maximum peak. This can result in periods where expensive resources are sitting idle or occasions of insufficient capacity. With cloud computing, you can access as much or as little capacity as you need and dynamically scale to meet actual demand, while only paying for what you use.

• Question 1508:

  What technology enables compute capacity to adjust as loads change?

  A. Load balancing
  B. Automatic failover
  C. Round robin
  D. Auto Scaling
  D. Auto Scaling

  ---

  Explanation/Reference:

  AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. Using AWS Auto Scaling, it's easy to setup application scaling for multiple resources across multiple services in minutes. The service provides a simple, powerful user interface that lets you build scaling plans for resources including Amazon EC2 instances and Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas. AWS Auto Scaling makes scaling simple with recommendations that allow you to optimize performance, costs, or balance between them. If you're already using Amazon EC2 Auto Scaling to dynamically scale your Amazon EC2 instances, you can now combine it with AWS Auto Scaling to scale additional resources for other AWS services. With AWS Auto Scaling, your applications always have the right resources at the right time.

• Question 1509:

  A company is planning to run a global marketing application in the AWS Cloud. The application will feature videos that can be viewed by users. The company must ensure that all users can view these videos with low latency. Which AWS service should the company use to meet this requirement?

  A. AWS Auto Scaling
  B. Amazon Kinesis Video Streams
  C. Elastic Load Balancing
  D. Amazon CloudFront
  D. Amazon CloudFront

  ---

  Explanation/Reference:

  The best option for the company to ensure that users can view videos with low latency would be to use Amazon CloudFront. CloudFront is a content delivery network (CDN) that speeds up the delivery of static and dynamic web content, such as HTML, CSS, JavaScript, and images, as well as videos.

• Question 1510:

  Which activity is a customer responsibility in the AWS Cloud according to the AWS shared responsibility model?

  A. Ensuring network connectivity from AWS to the internet
  B. Patching and fixing flaws within the AWS Cloud infrastructure
  C. Ensuring the physical security of cloud data centers
