AWS Certified Cloud Practitioner (CLF-C01)- Elastic Block Store (EBS)

The video tutorial provides an in-depth look at Amazon's Elastic Block Store (EBS), a service that offers persistent block storage for EC2 instances. It explains the replication and durability features of EBS, comparing it to Amazon S3. The tutorial covers key features like data persistence, encryption, and the ability to create snapshots. It also details the different types of EBS volumes, including SSD and HDD options, and their specific use cases. The video concludes with a preview of the next tutorial, which will demonstrate how to manage EBS volumes.

What is a key difference between EBS and Amazon S3 in terms of data replication?

• EBS replicates data across multiple regions.

• Amazon S3 does not replicate data.

• EBS replicates data within a single availability zone.

• Amazon S3 replicates data within a single availability zone.

Can you attach a single EBS volume to multiple EC2 instances simultaneously?

• No, EBS volumes cannot be attached to EC2 instances.

• Yes, but only if they are in the same availability zone.

• No, each EBS volume can only be attached to one instance at a time.

• Yes, you can attach it to multiple instances.

What feature of EBS allows you to restore data to a specific point in time?

• Data striping

• Volume expansion

• Snapshots

• Data replication

Which type of EBS volume is designed for intensive I/O workloads like databases?

• Provisioned IOPS SSD (I1)

• Cold HDD (C1)

• Throughput Optimized HDD (ST1)

• General Purpose SSD (GP2)

What is the maximum capacity of a General Purpose SSD (GP2) volume?

• 64 TB

• 32 TB

• 16 TB

• 1 TB

Which EBS volume type is the most cost-effective for infrequent access?

• Magnetic volumes

• Cold HDD

• General Purpose SSD

• Provisioned IOPS SSD

What is a characteristic of magnetic EBS volumes?

• They are suitable for infrequent access workloads.

• They offer the highest IOPS.

• They are the most expensive option.

• They cannot be used as boot volumes.
