TMP Network Design & Optimization 2

Question 1

A telecom manager needs to reduce end-to-end latency for a real-time voice application. Which optimization technique is MOST effective?

Accepted Answer

Implement QoS traffic prioritization

Answer

QoS prioritization queues voice packets ahead of less time-sensitive traffic, directly reducing latency for real-time applications.

Question 2

In a hierarchical network design, which layer is responsible for high-speed backbone switching between distribution blocks?

Accepted Answer

Core layer

Answer

The core layer provides high-speed, high-availability switching between distribution blocks without applying complex policies.

Question 3

A network experiences congestion on a primary WAN link. Which routing protocol feature automatically redistributes traffic to alternate paths?

Accepted Answer

Equal-cost multipath (ECMP)

Answer

ECMP load-balances traffic across multiple equal-cost paths, automatically utilizing alternate WAN links when one becomes congested.

Question 4

What is the primary purpose of network baseline documentation in optimization efforts?

Accepted Answer

To establish normal performance thresholds for anomaly detection

Answer

A network baseline captures normal performance metrics so deviations can be identified and addressed before they impact service quality.

Question 5

A TMP candidate is designing a network for a campus with 5,000 users. Which topology best balances redundancy and cost at the distribution layer?

Accepted Answer

Dual-homed star connecting to two core switches

Answer

A dual-homed star provides redundancy against core switch failure while avoiding the excessive cost and complexity of full mesh.
