NEW QUESTION # 233
Which of the following network devices operates as a bridge function?

A. Transceiver
B. Hub
C. Wireless access point
D. Media converter

Answer: D

Explanation:
A media converter is a network device that operates as a bridge function, which means it connects two different types of network media, such as copper and fiber optic cables, and converts signals between them.
This allows network devices that use different media types to communicate with each other over long distances or in different environments, without requiring major changes or upgrades to the existing network infrastructure.

NEW QUESTION # 234
A technician just finished building a new PC and needs to install a firmware update for the system board UEFI. The technician is experiencing issues while accessing the USB key. Which of the following features should the technician most likely disable in order to complete this task?

A. USB 3.0 support
B. Secure Boot
C. PXE boot capability
D. TPM security

Answer: B

Explanation:
Explanation
Secure Boot is a feature of UEFI (Unified Extensible Firmware Interface) that prevents unauthorized software from running during the boot process. Secure Boot verifies the digital signature of the boot loader and the operating system, and only allows them to run if they are signed by a trusted authority. However, Secure Boot can also prevent some legitimate software, such as firmware updates, from running if they are not signed or recognized by the system. Therefore, the technician may need to disable Secure Boot in order to install a firmware update for the system board UEFI from a USB key34. The other features are not likely to interfere with the firmware update, unless they are misconfigured or incompatible with the USB key.

NEW QUESTION # 237
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:

Which of the following is MOST likely causing the user's issue?

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

Answer: A

Explanation:
Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.
