Question

how do Technologies such a virtual machine and containers help improve operational efficiency?
1. by eliminating the need for cloud data centre altogether
2. by spreading energy consumption across multiple locations
3. by allowing multiple applications to run a single server
4. by reducing the consumer demand to Cloud Computing services ​

Answer 1

The right option is 2:

Explanation:

2. by spreading energy consumption across multiple locations

• Virtual machines and containers, for example, help increase operational efficiency by distributing energy use over various sites.

• Many applications can be executed on a single server, avoiding the need for additional servers and hence more hardware and energy.
• Finally, it enables you to run numerous processes at the same time, resulting in increased operational efficiency.

• The basic goal of virtual machines is to run various operating systems on the same piece of hardware at the same time.

Answer 2

Explanation for correct option

2:

1. Virtual machines and containers aid in increasing operational efficiency by distributing energy consumption across multiple sites.
2. Many applications can run on a single server, eliminating the need for additional servers and, as a result, more hardware and energy.
3. Finally, it allows you to run multiple processes concurrently, resulting in increased operational efficiency.

Explanation for incorrect options

1,3,4:

Virtual machines and containers do not improve efficiency by eliminating the need for cloud data centres entirely, allowing multiple applications to run on a single server, or lowering consumer demand for Cloud Computing services. ​

Thus, options 1, 3 and 4 are all incorrect.

Hence, option 2 is correct.
