This matches the description of Beau's setup with an external RAID array connected to his workstation for local backups.

Question 8

Rick needs to expand the storage for his company's large private cloud. Which of the following types of storage do they most likely use?

Accepted Answer

SAN (Storage Area Network) is most likely used for expanding storage in large private clouds due to its scalability and ability to connect to multiple servers, providing a high-speed network of shared storage devices.

Question 9

Terrance is designing storage for a startup company and needs to ensure from the beginning that it will be able to handle high levels of variety in high volumes and arriving in high velocity. Which of the following technologies is he designing for?

Accepted Answer

The description of handling high levels of variety, in high volumes, and arriving in high velocity directly corresponds to the three Vs (volume, velocity, variety) of Big Data. This indicates that Terrance is designing storage for Big Data.

Question 10

Martin wants to maintain an exact copy of the data from one of the data storage locations in a separate location for disaster recovery purposes. The copy of the data will not be actively used unless the systems have to failover to the copy. Which of the following describes the type of redundancy he is wanting to implement?

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.

Question 11

Daniel is looking for a good solution to store the log files from servers in his organization. He knows that the log files will never change. Which of the following describes the type of data he is looking to store and manage?

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?

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?

Accepted Answer

A relational database is best suited for managing various types of interrelated information like customer lists, products, inventory, and orders. It allows for efficient storage, querying, and management of data across different tables through relationships, which is essential for a customer relationship management application.

Question 14

Startup Inc. is developing a new application that they intend to use a cloud service provider to host. Initially, they plan on only launching the app in the United States and then growing from there once they have reached critical mass. Which of the following storage designs might they use initially in order to save on costs?

Accepted Answer

Regional storage is the most cost-effective option for Startup Inc. since they are initially launching the app in the United States only. This option allows for data to be stored in a specific geographic location, reducing costs compared to multi-regional storage, which is designed for applications that require global access to data.

Question 15

Roz is looking to save disk space on the servers by migrating log files older than 30 days to another server. Which of the following might she use to combine the files into one file that is smaller than the combined size of the originals?

Accepted Answer

Compression is the process of reducing the size of files by encoding information more efficiently, which is exactly what Roz is looking to do by combining the log files into one smaller file.

Question 16

Juanita wants to create a data replication system where the data is constantly written to two locations at the same time. Which of the following describes this type of configuration?

Accepted Answer

Synchronous replication ensures that data is written to two locations simultaneously, providing real-time data consistency and redundancy.

Question 17

Roberta is trying to find a way to save space on the SAN that acts as storage for all of the home directories in her organization. Which of the following might help Roberta accomplish this goal?

Accepted Answer

Deduplication is a data compression technique that eliminates duplicate copies of repeating data and is commonly used in storage systems to save space, which aligns with Roberta's goal of saving space on the SAN.

Question 18

Trent is designing the technology infrastructure to use at his company's new small office in the Caribbean. After researching the ISPs in the area, he sees that the amount of bandwidth available at that specific location is going to be rather limited. Which of the following may he want to install in order to provide local file storage for the office?

Accepted Answer

A NAS (Network Attached Storage) is designed to provide local file storage over a network, which is ideal for environments with limited bandwidth as it reduces the need for remote file access.

Question 19

Sophia needs to make sure that everything on certain systems gets backed up once per week. What is the technical term that is used to describe this type of backup?

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?

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.
