Answer: BF
A network technician is troubleshooting a connectivity issue. All users within the network report that they are unable to navigate to websites on the internet; however, they can still access local network resources. The technician issues a command and receives the following results: Pinging comptia.com [172.67.217.56] with 32 bytes of data: Reply from 172.67.217.56: TTL expired in transit. Reply from 172.67.217.56: TTL expired in transit. Reply from 172.67.217.56: TTL expired in transit. Reply from 172.67.217.56: TTL expired in transit. Which of the following best explains the result of this command?

A network engineer is configuring new switches. Some of the trunk ports are in a blocking state. Which of the following should the network engineer reconfigure?
Answer: A
When trunk ports are in a blocking state, it usually indicates an issue with spanning tree protocol (STP). STP is responsible for preventing loops in a network topology by blocking certain redundant paths. However, if STP misconfigurations occur, it might lead to ports being unnecessarily blocked. Therefore, the network engineer should reconfigure STP settings to ensure proper trunk port operation.

Which of the following transceiver types can support up to 40Gbps?
Answer: B
QSFP+ is an evolution of QSFP (quad small form-factor pluggable). QSFP can carry 4 channels simultaneously and each channel can handle 1 Gbit/s data rate- hence the name Quad SFP. Unlike QSFP, QSFP+ supports 4x 10 Gbit/s channels. And the 4 channels can be combined into a single 40 Gigabit Ethernet link. Its QSFP+

A building was recently remodeled in order to expand the front lobby. Some mobile users have been unable to connect to the available network jacks within the new lobby, while others have had no issues. Which of the following is the most likely cause of the connectivity issues?
Answer: B
Port security is a feature that restricts access to a switch port based on the MAC address of connected devices. If a mobile user’s device isn’t recognized (or exceeds the allowed number of MAC addresses), the port may be in a restricted state, preventing connectivity.

A network administrator for a small office is adding a passive IDS to its network switch for the purpose of inspecting network traffic. Which of the following should the administrator use?
Answer: B
Port mirroring (also known as SPAN - Switched Port Analyzer) is the process of forwarding a copy of network packets from one port on a network switch to another port, where the packets can be analyzed. In this scenario, the network administrator should use port mirroring to send a copy of the network traffic to the passive IDS (Intrusion Detection System) for inspection without interrupting the normal flow of traffic on the network. This allows the IDS to monitor the network traffic and detect any suspicious or malicious activity.
