B. Amazon EBS
C. Amazon EFS
D. Amazon FSx
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** Amazon S3 is an object storage service designed to store and retrieve large amounts of data with high durability and scalability. * **Why distractors are incorrect:** * **B (Amazon EBS):** Provides block storage volumes primarily for use with Amazon EC2 instances. * **C (Amazon EFS):** Provides managed elastic file storage for file-based workloads. * **D (Amazon FSx):** Provides managed file systems for specific file system technologies, such as Windows File Server or Lustre.Question 2
A company stores monthly reports in Amazon S3. The reports are accessed only once or twice each month, but when accessed, they must be retrieved immediately. The data must also be stored redundantly across multiple Availability Zones. Which S3 storage class is most appropriate?
A. S3 Standard-IA
B. S3 One Zone-IA
C. S3 Glacier Flexible Retrieval
D. S3 Glacier Deep Archive
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** S3 Standard-Infrequent Access (Standard-IA) is designed for data that is accessed less frequently but requires rapid retrieval. It stores data redundantly across multiple Availability Zones. * **Why distractors are incorrect:** * **B (S3 One Zone-IA):** Stores data in a single Availability Zone, so it does not meet the requirement for multi-AZ storage. * **C (S3 Glacier Flexible Retrieval):** Is intended for archival data and generally has retrieval times ranging from minutes to hours. * **D (S3 Glacier Deep Archive):** Is designed for long-term archival data that is rarely accessed and does not provide immediate retrieval.Question 3

A. Amazon EBS
B. Amazon S3
C. AWS Storage Gateway
D. Amazon EFS
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** Amazon Elastic Block Store (Amazon EBS) provides persistent block storage volumes that can be attached to EC2 instances and retain data independently of the instance lifecycle. * **Why distractors are incorrect:** * **B (Amazon S3):** Provides object storage and cannot be used as a standard block device for an EC2 operating system. * **C (AWS Storage Gateway):** Connects on-premises environments with cloud storage services; it is not the typical block storage solution for an EC2 database. * **D (Amazon EFS):** Provides shared file storage rather than block storage for a database volume.Question 4

A. EC2 instance store
B. Amazon EBS
C. Amazon S3 Standard
D. Amazon EFS
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** EC2 instance store provides temporary block-level storage physically attached to the host. It is suitable for temporary data such as caches, buffers, and scratch files, but the data is lost when the instance is stopped or terminated. * **Why distractors are incorrect:** * **B (Amazon EBS):** Provides persistent block storage that is designed to retain data independently of the EC2 instance. * **C (Amazon S3 Standard):** Provides durable object storage rather than local temporary block storage. * **D (Amazon EFS):** Provides shared, persistent file storage and is not intended as temporary host-attached scratch storage.Question 5
