You are deploying a database on multi EC2 instances which requires low latency and high throughput to support several million IOPS. It can withstand the loss of data on some EC2 instances. Which one will fit this use case ?

• EBS
• EFS
• Instance Store
• FSx

EFS locked to an AZ

• true
• false

Production team needs store a large amount of data which will be analyzed hourly and modified by multiple EC2 Linux instances. Data will continue to grow triples for next 6 months. Which one will fit this use case ?

• EBS
• EFS Standard Multi AZ
• EFS Standard 1 Zone
• EFS IA Multi AZ
• EFS IA 1 Zone

Sort the steps to create an encrypted EBS volume for EC2 instance from the unencrypted one

1 - Encrypt the snapshot

2 - Create a snapshot

3 - Attach the encrypted volume to the instance

4 - Create new volume from the snapshot

• 2 1 3 4
• 2 1 4 3
• 2 4 1 3
• 2 4 3 1

An application run on a group of Linux EC2 instances which need writes log using API calls. All log files must retained infinitely and will be analyzed by a reporting toll that must access all files concurrently. Which one will fit this use case ?

• EBS
• EFS
• Instance Store
• FSx

Under what circumstances will EC2 instance store data not be preserved? (choose all that apply)

• The associated security groups are changed.
• The instance is stopped
• The instance is rebooted
• The instance is terminated
• None of the above

Which of the following EBS volume types can be used as boot volumes when you create EC2 instances? (choose 2)

• Cold HDD
• Throughput-optimized HDD
• General-purpose SSD
• Provisioned-IOPS SSD

EFS Compatible with ___ based AMI

• Windows
• Mac
• Linux

Which of the following are features of EBS (choose 2)

• Data stored on EBS is automatically replicated within an AZ
• EBS data is automatically backed up to tape
• EBS volumes can be encrypted transparently to workloads on the attached instance.
• Data on an EBS volume is lost when the attached instance is stopped.
