  Explanation/Reference:

  ReliabilityThe Reliability pillar encompasses the ability of a workload to perform its intended function correctly and consistently when it's expected to. This includes the ability to operate and test the workload through its total lifecycle. You can find prescriptive guidance on implementation in the Reliability Pillar whitepaper. Design PrinciplesThere are five design principles for reliability in the cloud:

  1.

  Automatically recover from failure

  2.

  Test recovery procedures

  3.

  Scale horizontally to increase aggregate workload availability Stop guessing capacity

  4.

  Manage change in automation https://aws.amazon.com/blogs/apn/the-6-pillars-of-the-aws-well-architected-framework/

  A. Call the Descnbeinstances API operation and filter on the current instance ID Examine the EiasticGpuAssociations property
  B. Evaluate the GPU_AVA1LABLE environment variable
  C. Call the DescribeElasticGpus API operation
  D. Retrieve the instance type from the instance metadata
  A. Call the Descnbeinstances API operation and filter on the current instance ID Examine the EiasticGpuAssociations property

• Question 635:

  Which component of the AWS global infrastructure is made up of one or more discrete data centers that have redundant power, networking, and connectivity?

  A. AWS Region
  B. Availability Zone
  C. Edge location
  D. AWS Outposts
  B. Availability Zone

  ---

  Explanation/Reference:

  The component of the AWS global infrastructure that is made up of one or more discrete data centers that have redundant power, networking, and connectivity is B. Availability Zone.

  An Availability Zone is a separate data center within a region that has independent power, cooling, and networking, which are connected to other Availability Zones through high-bandwidth, low-latency links. By using multiple Availability Zones, customers can design and operate applications and services that are highly available, fault-tolerant, and scalable.

  A. Users can trade fixed expenses for variable expenses.
  B. Users can deploy all over the world in minutes.
  C. AWS offers increased speed and agility.
  D. AWS is responsible for patching the infrastructure.
  E. Users benefit from economies of scale.
  A. Users can trade fixed expenses for variable expenses.
  E. Users benefit from economies of scale.

  ---

  Explanation/Reference:

  Option A is correct because using the AWS Cloud allows users to pay only for the resources they consume, rather than investing in expensive on-premises hardware and software.

  Option E is correct because AWS Cloud provides massive economies of scale, meaning that the cost of running infrastructure is distributed across a vast number of users. This results in lower prices for users as compared to running their own infrastructure.
