Sample AWS Certification Cloud Practitioner 2022 questions

1. A retailer's traffic varies sharply during seasonal promotions. It wants capacity to expand when demand rises and shrink afterward, while avoiding payment for unused servers. Which cloud benefit best meets this need?
  1. High availability
  2. Fault tolerance
  3. Elasticity
  4. Data durability

Answer: C. Elasticity

Elasticity lets capacity increase or decrease with demand, helping the retailer pay for resources it uses. High availability and durability address uptime and data preservation rather than adjusting capacity.

2. A media company needs users around the world to receive cached copies of public images with low latency. Which AWS service is the most appropriate?
  1. Amazon CloudFront
  2. AWS Direct Connect
  3. Amazon RDS
  4. AWS Storage Gateway

Answer: A. Amazon CloudFront

Amazon CloudFront is a content delivery network that caches content at edge locations close to viewers. Direct Connect is a dedicated network connection, while RDS is a database service.

3. A company runs a production relational database on Amazon RDS and wants to improve availability if an Availability Zone fails, with minimal database administration. Which approach is best?
  1. Take a manual snapshot once per month.
  2. Increase the database storage size in its current Availability Zone.
  3. Move the database files to an Amazon S3 bucket.
  4. Enable a Multi-AZ deployment for the RDS DB instance.

Answer: D. Enable a Multi-AZ deployment for the RDS DB instance.

A Multi-AZ RDS deployment maintains a standby in another Availability Zone and supports failover, improving availability with a managed approach. A monthly snapshot is for recovery but does not provide that automatic availability.

4. Under the AWS shared responsibility model for an Amazon EC2 instance, which task is generally the customer's responsibility?
  1. Maintaining the physical security of the AWS data center
  2. Applying security patches to the guest operating system
  3. Maintaining the physical host servers
  4. Operating the network infrastructure between AWS data centers

Answer: B. Applying security patches to the guest operating system

For EC2, AWS secures the underlying infrastructure, while the customer manages the guest operating system, including its patches. Physical facilities, host hardware, and AWS backbone infrastructure are AWS responsibilities.

5. An administrator uses the AWS account root user only for tasks that require it. Which action most directly reduces the risk of someone taking over that account?
  1. Create an additional root user for emergencies.
  2. Share the root password with the operations team.
  3. Enable multi-factor authentication (MFA) for the root user.
  4. Use the root user for routine administration so activity is centralized.

Answer: C. Enable multi-factor authentication (MFA) for the root user.

MFA adds a second authentication factor to the especially powerful root account. Creating or sharing root credentials increases risk, and routine tasks should instead use appropriately permissioned IAM identities.
