File Storage
What are the differences between
instance stores and Amazon EBS
volumes?
Instance stores:
>Are ideal for temporary data that is not kept long term.
>When stopping or
terminating an Amazon EC2 instance, all the data written to the attached instance store is deleted.
Amazon EBS volumes:
>Are ideal for data that requires retention. >When stopping or terminating an Amazon EC2 instance, all the data on the attached EBS volume remains available.
Match following S3 storage classes with the correct descriptions:
- S3 Storage
- S3 Intelligent-Tiering
- S3 One Zone-IA
- S3 Glacier Deep Archive
- S3 Glacier Instance Retrieval
- S3 Glacier Flexible Retrieval
- S3 Standard-IA
A. Stores data in a single Availability Zone.
Has a lower storage price than S3 Standard-IA
B. Low-cost storage designed for data archiving.
Able to retrieve objects in milliseconds
C. Lowest-cost object storage class.
Able to retrieve objects within 12 hours
D. Designed for frequently accessed data.
Stores data in a minimum of three Availability Zones.
E. Ideal for data with unknown or changing access patterns.
Requires a small monthly monitoring and automation fee per object.
F. Lowest-cost object storage class.
Configurable retrieval
time from minutes to
hours
G. Ideal for infrequently accessed data.
Similar to S3 Standard but has a lower storage price and higher retrieval price
- D
- E
- A
- C
- B
- F
- G
You want to store data that
is infrequently accessed but
must be immediately
available when needed.
Which Amazon S3 storage
class should you use?
A. S3 Intelligent-Tiering
B. S3 Glacier Deep Archive
C. S3 Standard-IA
D. S3 Glacier Flexible Retrieval
C. S3 Standard-IA
The S3 Standard-IA storage class is ideal for data that is infrequently accessed but requires high availability when needed. Both S3 Standard and S3 Standard-IA
store data in a minimum of three Availability Zones. S3 Standard-IA provides the same level of availability as S3 Standard but at a lower storage price.
