SAA-C03 Flashcards
You need to create an exact copy of an existing instance. What can you use in order to do this faster?
AMI (Amazon Machine Images)
Sources of AMI
Public AMI, own AMI, Marketplace AMI
AMIs are bound in a specific region. True or False?
True
You need to store data with fastest I/O performance possible. The data you store will only be temporary (ephemeral). What type of storage can you use?
a. EBS
b. EFS
c. Instance Store
d. USB
What EBS Volume Type do you choose if you need high IOPS performance
io1/io2
Which EBS Volume Type offers Multi-Attach
io1/io2
Multi-Attach only allows up to __ EC2 instances at a time
16
EBS Encryption leverages keys from KMS that uses what encryption algorithm
AES-256
You cannot directly encrypt existing unencrypted volumes or snapshots.
What are two ways to have encrypted volumes?
- Create a volume out of a snapshot and allow encryption.
- Enable encryption so newly created volumes and snapshots will be encrypted.
When you create a volume out of an “encrypted” snapshot, the created volume will be unencrypted. True or False?
False
When you create a volume out of an “unencrypted” snapshot, you have an option to make it encrypted. True or False?
True
You can create a snapshot copy of an EBS and use it on a different AZ or region. True or False?
True
EBS can only be attached to EC2s that lie within the same AZ. But if your instances need to share data across multi-AZ, what can you use?
EFS (Elastic File System)
2 Performance Modes in EFS
- General Purpose
- Max I/O
2 Throughput Modes in EFS
- Bursting
- Provisioned
