Question 1:

What is Simple Storage Service (S3)?

A) A file-based storage service

B) An object-based storage service

C) A block-based storage service

A) The name must start with a specific letter

B) The name must be in all caps

C) The name must be a specific length

D) The name must be unique

Explanation:

Answer - D

When naming an S3 bucket, it uses a universal namespace, and the bucket names must be unique.

Question 6:

What is the advantage of using object storage over file-based or block-based storage?

A) It provides unlimited storage

B) It replicates data across multiple availability zones

C) It manages data as objects, rather than files or blocks

D) It is cheaper than other storage options

Explanation:

Answer - C

Object storage manages data as objects, which eliminates the need to worry about underlying infrastructure.

Question 7:

Which S3 storage class is best suited for long-term archival data?

A) Standard

B) Intelligent Tiering

C) Glacier

D) One Zone-IA

Explanation:

Answer - C

Glacier is best suited for long-term archival data because it provides extremely cheap storage, but retrieval can take minutes to an hour.

Question 8:

What is Intelligent Tiering in S3?

A) An S3 storage class that uses machine learning to determine the appropriate storage class for data

B) An S3 storage class that provides the fastest access to data

C) An S3 storage class that provides the cheapest storage option

D) An S3 storage class that is best suited for long-term archival data

Explanation:

Answer - A

Intelligent Tiering uses machine learning to analyze object usage and determine the appropriate storage class for data, helping to save costs.

Question 9:

What is the key feature of S3 storage?

A) It's file-based storage

B) It's object-based storage

C) It's block-based storage

D) It's relational database storage

Explanation:

Answer - B

S3 storage is an object-based storage service where data is stored in the form of objects, which consist of a key, value, version ID, and metadata.

Question 10:

What is the availability of the standard storage class in S3?

A) 99.5%

B) 99.9%

C) 99.99%

D) Not applicable

Explanation:

Answer - C

The standard storage class in S3 has a 99.99% availability guarantee, which means it is highly available.

Question 11:

Which S3 storage class is suitable for long-term archival data?

A) Standard

B) One Zone-IA

C) Glacier

D) Intelligent-Tiering

Explanation:

Answer - C

Glacier is a low-cost S3 storage class that is suitable for long-term archival data. It has a retrieval time of minutes to hours, but it is the cheapest tier of storage.

Question 12:

What is the default setting for bucket access in S3?

A) Public access allowed

B) Private access only

C) Read-only access

D) Write-only access

Explanation:

Answer - B

When a bucket is created in S3, it is set to private access only by default. Public access has to be explicitly granted through bucket policies or access control lists (ACLs).

Question 13:

What is the purpose of S3 logging?

A) To monitor user activity on the S3 service

B) To generate usage reports for billing purposes

C) To track object access and changes in granular detail

D) To provide real-time metrics on S3 performance

Explanation:

Answer - C

S3 logging allows users to track all object access and changes in granular detail. This information can be used for security and compliance purposes.

Question 14:

What is the difference between bucket policies and access control lists (ACLs) in S3?

A) Bucket policies are simpler to use than ACLs

B) ACLs are a legacy feature and should not be used

C) Bucket policies provide more complex and rich rules than ACLs

D) ACLs are only used for static S3 hosting

Explanation:

Answer - C

Bucket policies are written in JSON format and provide more complex and rich rules for controlling access to S3 buckets and objects. ACLs are a simpler feature but are still used in certain use cases.

Question 15:

What does SSE stand for in S3 encryption?

A) Simple Storage Encryption

B) Server-Side Encryption

C) Security Standard Encryption

D) Service-Side Encryption

Explanation:

Answer - B

SSE stands for Server-Side Encryption, and it's an algorithm used for encryption that S3 handles by itself.

Question 16:

What is the difference between SSE and SSE-KMS in S3?

A) SSE is managed by AWS, and SSE-KMS is managed by the user.

B) SSE-KMS is an algorithm used for encryption, and SSE is a key management service.

C) SSE-KMS uses envelope encryption, and SSE does not.

D) SSE is only used for SSL/TLS encryption, and SSE-KMS is used for server-side encryption.

Explanation:

Answer - C

SSE-KMS uses envelope encryption, which means the key is encrypted with another key, while SSE does not.

Question 17:

What is client-side encryption in S3?

A) Encryption done by AWS on the client-side.

B) Encryption done by the user on their own machine before uploading to S3.

C) Encryption done by the user on S3 after uploading the files.

D) Encryption done by a third-party client application on S3.

Client-side encryption involves the user encrypting the files locally on their machine before uploading to S3.

Question 18:

What is the consistency model for new objects written to S3?

A) Read after write consistency

B) Eventual consistency

C) Strong consistency

D) None of the above

Explanation:

Answer - A

When you write new objects to S3, the consistency model is Read after write consistency. This means that as soon as you upload the data, you can immediately read the data and it is consistent.

Question 19:

What is the consistency model for overwritten or deleted objects in S3?

A) Read after write consistency

B) Eventual consistency

C) Strong consistency

D) None of the above

Explanation:

Answer - B

When you overwrite or delete objects in S3, the consistency model is Eventual consistency. This means that it takes time for S3 to replicate the changes to all the other availability zones (AZs). So, if you immediately read the data after
