I would ask about this question, I think D is not really right but the other options are totally wrong.
What do you think Guys, am i wrong?
What is the basic function of the Cisco Borderless Architecture access layer?
- aggregates Layer 2 broadcast domains
- aggregates Layer 3 routing boundaries
- provides access to the user
- provides fault isolation
No, you are wrong, C is the right option, not D, I think the question is poorly worded.
The basic function of the Cisco Borderless Architecture access layer is to provide access to the user. Thus, the answer is C, not D.
A function of the Cisco Borderless Architecture access layer is providing network access to the users. However, Layer 2 broadcast domain aggregation, Layer 3 routing boundaries aggregation, and high availability are distribution layer functions. In addition, The core layer provides fault isolation and high-speed backbone connectivity.
This question is quite confusing. I also see D is also somehow right. But best and relevant answer is C.
