Microsoft Networking Essentials Exam Quality Control & Assurance 5

Question 1

What is the primary purpose of testing network redundancy as part of quality assurance?

Accepted Answer

Verifying that failover mechanisms work before an actual failure occurs

Answer

Redundancy testing validates that backup paths and systems activate correctly so failures don't cause unplanned outages.

Question 2

A network team implements change management procedures as part of QA. What is the main benefit?

Accepted Answer

Preventing unauthorized changes that could degrade network performance

Answer

Change management ensures all network modifications are reviewed, approved, and documented to avoid unintended outages.

Question 3

Which Ethernet error type occurs when a frame is smaller than the minimum 64-byte size?

Accepted Answer

Runt

Answer

Runt frames are smaller than the 64-byte minimum Ethernet frame size and are usually caused by collisions or NIC failures.

Question 4

What does MTTR (Mean Time to Repair) measure in network quality assurance?

Accepted Answer

Average time required to restore a failed network component to operation

Answer

MTTR measures how quickly the team can diagnose and fix failures, reflecting the efficiency of support processes.

Question 5

Which feature on a managed switch helps ensure consistent network quality by preventing broadcast storms?
