Routing and Switching

Correct Answer: Trunking

In the given scenario, the network administrator is experiencing connectivity issues between workstations and a VLAN configured switch. The issue most likely resides in the Trunking configuration. Trunking is the process of enabling communication between VLANs by allowing multiple VLANs to use the same network link. If there is a fault in trunking configuration, it can lead to connectivity issues between workstations and the VLAN. On the other hand, Firewall Rules is probably not the right place to look because these control traffic to and from the network, but not within the network between workstations and switches. Port Mirroring is a feature that enables the copying of traffic from one port to another for analysis, which is unrelated to this issue. PoE (Power over Ethernet) provides power to a network device over the same cable that provides the network connection, but it doesn’t affect network connectivity between workstations and a VLAN configured switch.

Correct Answer: WPA2

The best non-WPA3 fallback option for strengthening wireless network security is WPA2. WPA2 is the direct predecessor to WPA3 and thus offers a high level of security, although not as robust as WPA3 WEP is not a strong fallback option as it is an outdated security protocol with known vulnerabilities that make it relatively easy to crack Open Wi-Fi is the least secure option, as it does not implement any form of encryption or protection against unauthorized access MAC Filtering, while it can be part of a security strategy, is not a substitute for a secure wireless protocol. MAC addresses can be easily spoofed or manipulated, allowing potential intruders to bypass such filtering.

Correct Answer: Quality of Service (QoS)

Quality of Service (QoS) is designed to handle these kind of network issues. It assigns a priority to each type of traffic and reserves a certain portion of the network's resources for that type of traffic, effectively avoiding issues such as significant packet loss during peak hours. Dynamic Routing Protocol, meanwhile, is used to find and maintain the routes in the network. It is not directly related to packet loss during peak hours. MAC Address Filtering restricts access to a network, based on MAC Address. This feature is used for security, not to resolve issues like packet loss. And Broadcast Suppression minimizes network disruption by stopping unnecessary broadcast traffic. It could help to improve performance but it is unlikely to be the main cause of network slowdown during peak hours.
