Q71

A company needs to share their EBS volume snapshots with another AWS account securely. What should they do?

  • A Change snapshot permissions to public
  • B Share the snapshot via resource sharing
  • C Share using IAM roles only
  • D Copy the snapshot to S3
Explanation Snapshot permissions can be shared with another account securely via resource sharing; others either expose it unnecessarily or are ineffective.
Q72

What happens when you configure an Auto Scaling Group to use a mixed instance type?

  • A Only one instance type is used
  • B It reduces cost automatically
  • C Multiple instance types can be utilized
  • D It limits scaling to an instance type
Explanation Mixed instance types allow flexibility and optimal utilization, while others limit or misrepresent its functionality.
Q73

Which service allows you to run code in response to events?

  • A AWS Lambda
  • B Amazon EC2
  • C Amazon RDS
  • D Amazon S3
Explanation AWS Lambda is designed for event-driven code execution, unlike the others which are used for compute or storage purposes.
Q74

A company needs highly available storage with automatic synchronization. Which service should they use?

  • A AWS EFS
  • B AWS S3
  • C AWS Glacier
  • D Amazon Redshift
Explanation AWS EFS provides shared, highly available storage, while S3 is for object storage without synchronization between instances.
Q75

  • A Access is granted.
  • B Access is denied.
  • C Access depends on S3 settings.
  • D Access must be requested again.
Explanation IAM operates on the principle of least privilege, so explicit denies take precedence over allows.
Q76

Which AWS service provides fully managed event-driven computing?

  • A AWS Lambda
  • B AWS EC2
  • C AWS S3
  • D AWS CloudFormation
Explanation AWS Lambda allows you to run code in response to events without managing servers, unlike EC2 which needs provisioning.

A company needs to restrict access to an S3 bucket based on user attributes. Which AWS feature should they use?

  • A IAM Policies
  • B Bucket Policies
  • C S3 Access Points
  • D IAM Roles
Explanation IAM Policies can specify conditions that allow user attribute-based restrictions, unlike the other options that are less flexible.

You are configuring a DynamoDB table. What happens if you exceed your provisioned write capacity?

  • A Writes are throttled
  • B Writes succeed with additional charges
  • C Table is deleted
  • D Read capacity is affected
Explanation Exceeding provisioned write capacity leads to throttling of writes, while other options do not accurately describe the behavior.
Q79

Which service provides a fully managed NoSQL database?

  • A Amazon DynamoDB
  • B Amazon RDS
  • C Amazon ElastiCache
  • D Amazon Redshift
Explanation DynamoDB is a NoSQL service; RDS is for SQL databases.
