Question 12

Which AWS services/features support High Availability by default? (Select two)
- Subnet
- Amazon Elastic Block Store (Amazon EBS)
- Amazon DynamoDB
- Instance Store
- Amazon Elastic File System (Amazon EFS)

Answer 12

• Amazon DynamoDB
• Amazon Elastic File System (Amazon EFS)

Subnet - A subnet is a range of IP addresses in your VPC. You can create AWS resources, such as EC2 instances, in specific subnets. Each subnet must reside entirely within one Availability Zone and cannot span multiple Availability Zones.

Amazon Elastic Block Store (Amazon EBS) - Amazon Elastic Block Store (Amazon EBS) is an easy to use, high-performance block storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction-intensive workloads at any scale. EBS volumes are replicated within an Availability Zone (AZ) and can easily scale to petabytes of data.

Instance Store - As Instance Store volumes are tied to an EC2 instance, they are also single Availability Zone (AZ) entities.

Question 13

Answer 13

AWS Config

Question 14

A company has a static website hosted on an Amazon Simple Storage Service (Amazon S3) bucket in an AWS Region in Asia. Although most of its users are in Asia, now it wants to drive growth globally. How can it improve the global performance of its static website?
- Use Amazon CloudFormation to improve the performance of your website
- Use Amazon CloudFront to improve the performance of your website
- Use AWS Web Application Firewall (AWS WAF) to improve the performance of your website
- Use Amazon S3 Transfer Acceleration (Amazon S3TA) to improve the performance of your website

Answer 14

Use Amazon CloudFront to improve the performance of your website

Amazon S3 Transfer Acceleration (Amazon S3TA) enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. Amazon S3 Transfer Acceleration (Amazon S3TA) takes advantage of Amazon CloudFront’s globally distributed edge locations. As the data arrives at an edge location, data is routed to Amazon S3 over an optimized network path. Amazon S3 Transfer Acceleration (Amazon S3TA) cannot be used to improve the performance of a static website.

Question 16

Which of the following statements are true about Cost Allocation Tags in AWS Billing? (Select two)
- For each resource, each tag key must be unique, and each tag key can have only one value
- You must activate both AWS generated tags and user-defined tags separately before they can appear in Cost Explorer or on a cost allocation report
- For each resource, each tag key must be unique, but can have multiple values
- Tags help in organizing resources and are a mandatory configuration item to run reports
- Only user-defined tags need to be activated before they can appear in Cost Explorer or on a cost allocation report

Answer 16

• For each resource, each tag key must be unique, and each tag key can have only one value
• You must activate both AWS generated tags and user-defined tags separately before they can appear in Cost Explorer or on a cost allocation report

A Cost Allocation Tag is a label that you or AWS assigns to an AWS resource. Each tag consists of a key and a value. For each resource, each tag key must be unique, and each tag key can have only one value. You can use tags to organize your resources, and cost allocation tags to track your AWS costs on a detailed level.

AWS provides two types of cost allocation tags, an AWS generated tags and user-defined tags. AWS defines, creates, and applies the AWS generated tags for you, and you define, create, and apply user-defined tags. You must activate both types of tags separately before they can appear in Cost Explorer or on a cost allocation report.

Question 22

AWS Identity and Access Management (AWS IAM) policies are written as JSON documents. Which of the following are mandatory elements of an IAM policy?
- Effect, Sid
- Action, Condition
- Sid, Principal
- Effect, Action

Answer 22

Effect, Action

A JSON policy document includes these elements:

Optional policy-wide information at the top of the document
One or more individual statements
Each statement includes information about a single permission. The information in a statement is contained within a series of elements.

Version – Specify the version of the policy language that you want to use. As a best practice, use the latest 2012-10-17 version.

Statement – Use this main policy element as a container for the following elements. You can include more than one statement in a policy.

Sid (Optional) – Include an optional statement ID to differentiate between your statements.

Effect – Use Allow or Deny to indicate whether the policy allows or denies access.

Principal (Required in only some circumstances) – If you create a resource-based policy, you must indicate the account, user, role, or federated user to which you would like to allow or deny access. If you are creating an IAM permissions policy to attach to a user or role, you cannot include this element. The principal is implied as that user or role.

Action – Include a list of actions that the policy allows or denies.

Resource (Required in only some circumstances) – If you create an IAM permissions policy, you must specify a list of resources to which the actions apply. If you create a resource-based policy, this element is optional. If you do not include this element, then the resource to which the action applies is the resource to which the policy is attached.

Condition (Optional) – Specify the circumstances under which the policy grants permission.
