CompTIA A+ Core 1 (220-1101) — Question 553

A user on a SOHO network is unable to watch online videos, even at 240 pixels. The technician runs ipconfig from the user's computer and records the following:
Connection-specific DNS Suffix .: lan
Link-local IPV6 Address.........: fe80::1585:7fb2:b05f:7102%12
IPv4 Address....................: 192.168.1.131
Subnet Mask.....................: 255.255.255.0
Default Gateway.................: 192.168.1.1
The technician then connects a test laptop to the router via the user's Cat 5 cable and records the following information:

Download: 85 mbps -

Upload: 22 mbps -

Ping: 28 ms -
Which of the following is MOST likely causing the user's issue?

Answer options

• A. Incorrect IP address
• B. Faulty NIC
• C. Misconfigured default gateway
• D. Bad network cable

Correct answer: B

Explanation

The correct answer is B, as the user's network interface card (NIC) may be faulty, preventing successful video streaming despite the network showing good performance with the test laptop. The other options are less likely; the IP address is correctly assigned, the default gateway is configured correctly, and the cable works fine since the test laptop functions well.
