NEW QUESTION # 106
A technician is troubleshooting a computer issue for a user who works in a new annex of an office building. The user is reporting slow speeds and intermittent connectivity. The computer is connected via a Cat 6 cable to a distribution switch that is 492ft (150m) away.
Which of the following should the technician implement to correct the issue?

A. Enable the computer to support jumbo frames.
B. Install an access switch in the annex and run fiber to the
distribution switch.
C. Increase the bandwidth allocation to the computer.
D. Run a Cat 7 cable from the computer to the distribution
switch.

Answer: B

Explanation:
The maximum recommended length for Ethernet cable runs is 100 meters (328 feet). At 150 meters, the Cat 6 cable is too long, causing signal degradation and connectivity issues. Running fiber from the distribution switch to an access switch in the annex will allow for reliable connectivity over longer distances, as fiber can cover greater distances without signal loss.

NEW QUESTION # 107
A network administrator needs to set up a multicast network for audio and video broadcasting. Which of the following networks would be the most appropriate for this application?

A. 224.0.0.0/24
B. 192.168.0.0/24
C. 240.0.0.0/24
D. 172.16.0.0/24

Answer: A

Explanation:
Understanding Multicast:
Multicast IP Address Range: The multicast address range is from 224.0.0.0 to 239.255.255.255, designated for multicast traffic.
Multicast Applications:
Use Case: Multicast is used for one-to-many or many-to-many communication, suitable for applications like audio and video broadcasting where the same data is sent to multiple recipients simultaneously.
Appropriate Network Selection:
224.0.0.0/24 Network: This range is reserved for multicast addresses, making it the appropriate choice for setting up a multicast network.
Comparison with Other Options:
172.16.0.0/24: Part of the private IP address space, used for private networks, not designated for multicast.
192.168.0.0/24: Another private IP address range, also not for multicast.
240.0.0.0/24: Reserved for future use, not suitable for multicast.
Reference:
CompTIA Network+ study materials on IP address ranges and multicast.

NEW QUESTION # 109
Newly crimped 26ft (8m) STP Cat 6 patch cables were recently installed in one room to replace cables that were damaged by a vacuum cleaner. Now, users in that room are unable to connect to the network. A network technician tests the existing cables first. The 177ft (54m) cable that runs from the core switch to the access switch on the floor is working, as is the 115ft (35m) cable run from the access switch to the wall jack in the office. Which of the following is the most likely reason the users cannot connect to the network?

A. An incorrect pinout on the patch cable is being used.
B. Mixed UTP and STP cables are being used.
C. The cable distance is exceeded.
D. The patch cables are not plenum rated.

Answer: A

Explanation:
An incorrect pinout on the patch cable could prevent network connectivity due to mismatched wiring.
Even if the cables are the correct length and type, a pinout issue can cause continuity problems and prevent data transmission. Proper crimping with the correct pinout is essential for network cables to function. (Reference: CompTIA Network+ Study Guide, Chapter on Network Media and Topologies)
