AWS Certified Solutions Architect Associate (SAA-C03) - EBS and EC2

The video tutorial explains the importance of storage for instances, focusing on Elastic Block Store (EBS) as a persistent storage solution. It contrasts persistent storage with non-persistent options like S3, highlighting the need for EBS when changes need to be saved. The tutorial also covers EBS optimization for enhanced performance, detailing instance types that support high IOPS levels. It concludes with considerations for selecting the right instance type and storage, emphasizing that free tier instances do not support EBS optimization.

What is the primary benefit of using Elastic Block Store (EBS) with instances?

• It provides temporary storage.

• It allows for persistent storage of changes.

• It is cheaper than other storage options.

• It automatically scales with instance size.

In which scenario might you not need to use EBS for storage?

• When using Windows OS.

• When storing large databases.

• When running a network appliance.

• When using a typical Linux OS.

Which storage type is used for saving configurations in network appliances?

• Magnetic Storage

• S3 Bucket

• Non-volatile RAM (NV RAM)

• Elastic Block Store (EBS)

Why is EBS optimization important when using SSDs?

• It simplifies the storage management.

• It increases the storage capacity.

• It reduces the cost of storage.

• It enhances the performance of the storage.

What is a key consideration when selecting an instance type for high IOPS?

• The instance type must be EBS-optimized.

• The instance type should be the cheapest available.

• The instance type must be part of the free tier.

• The instance type should have the largest storage capacity.

Which of the following is true about free tier instances in relation to EBS optimization?

• They support EBS optimization.

• They do not support EBS optimization.

• They offer the highest IOPS.

• They are the most cost-effective for high performance.

What is the maximum IOPS supported by a C4.8X large instance?

• 16,000

• 8,000

• 32,000

• 4,000
