- Which AWS service provides a simple and scalable shared file storage solution for use with Linux-based AWS and on-premises servers?
- A. Amazon S3
- B. Amazon Glacier
- C. Amazon EBS
- D. Amazon EFS
Answer
Correct Answer: D
Explanation:
- Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file system for use with AWS Cloud services and on-premises resources.
- It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.
- Amazon EFS is designed to provide the throughput, IOPS, and low latency needed for Linux workloads.
- Throughput and IOPS scale as a file system grows and can burst to higher throughput levels for short periods of time to support the unpredictable performance needs of file workloads.
- For the most demanding workloads, Amazon EFS can support performance over 10 GB/sec and up to 500,000 IOPS.

- A. Dedicated Hosts
- B. Reserved Instances
- C. On-Demand Instances
- D. No Upfront Reserved Instances
Answer
Correct Answer: A
Explanation:
- Use Dedicated Hosts to launch Amazon EC2 instances on physical servers that are dedicated for your use.

- A. Amazon Elastic Block Store (Amazon EBS)
- B. Amazon Machine Image
- C. Amazon EC2 Systems Manager
- D. Amazon AppStream 2.0
Answer
Correct Answer: B

- To use Amazon EC2, you simply:
- Select a pre-configured, templated Amazon Machine Image (AMI) to get up and running immediately. Or create an AMI containing your applications, libraries, data, and associated configuration settings.
- Configure security and network access on your Amazon EC2 instance.
- Choose which instance type(s) you want, then start, terminate, and monitor as many instances of your AMI as needed, using the web service APIs or the variety of management tools provided.
- Determine whether you want to run in multiple locations, utilize static IP endpoints, or attach persistent block storage to your instances.
- Pay only for the resources that you actually consume, like instance-hours or data transfer.

- How would an AWS customer easily apply common access controls to a large set of users?
- A. Apply an IAM policy to an IAM group.
- B. Apply an IAM policy to an IAM role.
- C. Apply the same IAM policy to all IAM users with access to the same workload.
- D. Apply an IAM policy to an Amazon Cognito user pool.
Answer
Correct Answer: A
Explanation:
- Instead of defining permissions for individual IAM users, it’s usually more convenient to create groups that relate to job functions (administrators, developers, accounting, etc.).
- Next, define the relevant permissions for each group. Finally, assign IAM users to those groups. All the users in an IAM group inherit the permissions assigned to the group.
- That way, you can make changes for everyone in a group in just one place. As people move around in your company, you can simply change what IAM group their IAM user belongs to.

Answer
Correct Answer: BE
- Which of the following is an AWS Cloud architecture design principle?
- A. Implement single points of failure.
- B. Implement loose coupling.
- C. Implement monolithic design.
- D. Implement vertical scaling.
Answer
Correct Answer: B
Explanation:
- Loose coupling between services can also be done through asynchronous integration. It involves one component that generates events and another that consumes them.
- The two components do not integrate through direct point-to-point interaction, but usually through an intermediate durable storage layer.
- This approach decouples the two components and introduces additional resiliency.
- So, for example, if a process that is reading messages from the queue fails, messages can still be added to the queue to be processed when the system recovers.

- Which of the following security measures protect access to an AWS account? (Select TWO.)
- A. Enable AWS CloudTrail.
- B. Grant least privilege access to IAM users.
- C. Create one IAM user and share with many developers and users.
- D. Enable Amazon CloudFront.
- E. Activate multi-factor authentication (MFA) for privileged users.
Answer
Correct Answer: BE
Explanation:
- If you decided to create service accounts (that is, accounts used for programmatic access by applications running outside of the AWS environment) and generate access keys for them, you should create a dedicated service account for each use case.
- This will allow you to restrict the associated policy to only the permissions needed for the particular use case, limiting the blast radius if the credentials are compromised.
- For example, if a monitoring tool and a release management tool both require access to your AWS environment, create two separate service accounts with two separate policies that define the minimum set of permissions for each tool.
- Which service provides a hybrid storage service that enables on-premises applications to seamlessly use cloud storage?
- A. Amazon Glacier
- B. AWS Snowball
- C. AWS Storage Gateway
- D. Amazon Elastic Block Storage (Amazon EBS)
Answer

- Which of the following is an important architectural design principle when designing cloud applications?
- A. Use multiple Availability Zones.
- B. Use tightly coupled components.
- C. Use open source software.
- D. Provision extra capacity.
Answer
Correct Answer: A
Explanation:
- Data Center resilience is practiced through Availability Zones across data centers that reduce the impact of failures.
- Fault isolation improvement can be made to traditional horizontal scaling by sharding (a method of grouping instances into groups called shards, instead of sending the traffic from all users to every node like in the traditional IT structure.)
