A) Duplexing
B) Mirroring
C) Snapshot
D) Tokenization

Accepted Answer

Mirroring is the process of creating an exact copy of data from one storage location to another. This is done for redundancy and disaster recovery purposes, ensuring that if the primary data source fails, there is an immediate copy available for failover, which matches Martin's requirements.

D) RTT

Accepted Answer

WORM (Write Once, Read Many) storage is designed for data that does not change once it has been written, making it ideal for storing log files that do not need to be modified after creation.

Question 12

Alexandra has scheduled a full backup of one of the servers she manages for the first day of every month. Every week after that, any data that has changed since the previous backup of any kind is backed up. Which of the following describes these weekly backups?
A) Piecemeal
B) Incremental
C) Additive
D) Differential

Accepted Answer

Incremental backups save only the data that has changed since the last backup, regardless of type, which matches the description given.

Question 13

Julia is designing a new customer relationship management application that will contain a number of types of information: customer list, products, inventory, orders, etc. Which of the following best suits the method of how she may want to store this data?

A) Complete
B) Exhaustive
C) Full
D) Thorough

Accepted Answer

The technical term used to describe a backup where everything on the system is copied is a "Full" backup. This type of backup copies all files and folders, providing a complete snapshot of the system at the point in time the backup was taken.

Question 20

Lorna manages a private cloud with 500 terabytes of storage. However, the servers in the cloud have a total provisioned footprint of 800 terabytes. Which of the following describes the provisioning model that she is using?
A) SOS provisioning
B) JIT provisioning
C) Thin provisioning
D) Thick provisioning

Accepted Answer

Thin provisioning is a method where storage space is allocated on demand from a shared pool of storage, which can lead to a situation where the total provisioned space across all servers and applications is greater than the actual physical storage capacity available. This is because thin provisioning allows for over-allocation of storage, assuming not all allocated space will be used at the same time. In this scenario, 800 terabytes are provisioned despite having only 500 terabytes of actual storage, indicating thin provisioning is being used.
