EXIN Cloud Data Centres and Services — Question 2

What is the main disadvantage of using a ToR (Top of Rack) design?

Answer options

• A. A single ToR (Top of Rack) switch is more expensive than an EoR (End of Row) switch.
• B. You need a separate rack to install all your ToR (Top of Rack) switches.
• C. There will be more switches to manage.
• D. A ToR (Top of Rack) switch has only optical interfaces.

Correct answer: C

Explanation

The correct answer is C because a ToR design typically involves multiple switches for each rack, leading to increased complexity in management. Option A is incorrect as it compares costs without addressing management issues, B is false since ToR switches are usually installed within the same rack, and D is misleading because ToR switches can have various interface types, not just optical.
