Failure Analysis

Answer 8

Involves analyzing both the physical and virtual infrastructure components to identify systems that are susceptible to a single point of failure and implementing fault-tolerance mechanisms.

Question 9

Answer 9

The failure of a component that can terminate the availability of the entire system or IT service.

Question 10

Data Archiving

Answer 10

The process of moving data that is no longer actively used from primary storage to a low-cost secondary storage.

Question 11

Disaster Recovery

Answer 11

Restore production data to an operational state after disaster.

Question 12

Operational Recovery

Answer 12

Restore data in the event of data loss or logical corruptions that may occur during routine processing.

Question 13

Backup Granularity

Answer 13

Depends on business needs and the required RTO/RPO.

Question 14

Cumulative Backup

Answer 14

Copies the data that has changed since the last full backup. Takes longer than an incremental backup but faster to restore.

Question 15

Incremental Backup

Answer 15

copies the data that has Changed since the last full or incremental backup, whichever occurred more recently. Faster than a full backup.

Question 16

Bare-Metal Recovery (BMR)

Answer 16

A backup in which all metadata, system information, and application configurations are appropriately backed up for a full system recovery.

Question 17

Data Deduplication

Answer 17

The process of identifying and eliminating redundant data.

Question 18

Fixed Content

Answer 18

Aged data that is less likely to be changed.

Question 19

Archival

Answer 19

Preserve transaction records, email, and other business work products for regulatory compliance.

Question 20

Archiving Agent

Answer 20

Software installed on the application server. Responsible for scanning the data that can be archived based on the policy defined on the archiving server.

Question 21

Archiving Server

Answer 21

Software installed on a host that enables administrators to configure policies for archiving data.

Question 22

Archiving Storage Device

Answer 22

Stores fixed content.

Question 23

Source

Answer 23

A host accessing the production data.
