Question 1

What is the purpose of an out-of-band (OOB) management network in a data center?

Accepted Answer

To manage network and server devices independently of the production network

Answer

An OOB management network provides a separate, dedicated path to manage devices even when the production network is down, enabling remote troubleshooting and recovery.

Question 2

Which standard defines Link Aggregation Control Protocol (LACP) used to bundle multiple physical links into one logical link?

Accepted Answer

IEEE 802.3ad

Answer

IEEE 802.3ad (now incorporated into 802.1AX) defines LACP, which dynamically negotiates and manages link aggregation groups (LAGs) for increased bandwidth and redundancy.

Question 3

In data center design, what is a 'Meet-Me Room' (MMR)?

Accepted Answer

A space where external carriers and internet exchanges interconnect with the data center

Answer

A Meet-Me Room is a neutral area within a data center where multiple carriers, ISPs, and tenants can interconnect their networks to exchange traffic.

Question 4

What is the function of a patch panel in a structured cabling system?

Accepted Answer

To provide a central termination point for horizontal cables, enabling flexible cross-connection

Answer

A patch panel consolidates cable terminations in one location, allowing administrators to quickly reconfigure connections using short patch cords without touching permanent cable runs.

Question 5

Which redundancy model provides two completely independent network paths from server to core, ensuring no single failure affects connectivity?

Accepted Answer

2N redundancy

Answer

2N redundancy provides two fully independent and equal-capacity network paths, meaning the entire second path can support all traffic if the first path fails completely.
