The engineer moves the connection lo a different switchport. but a link still cannot be obtained. When the engineer puts a tone generator on (he infrastructure cable, no tone is heard at the far end. Which of the following issues is the engineer MOST likely trying to find?
Correct Answer:
B
A break in the cable means that there is no electrical continuity between the two ends of the cable, which prevents the signal from reaching the switch. A tone generator is a device that sends an audible signal through the cable, and if no tone is heard at the far end, it indicates a break in the cable.

A company built a new building at its headquarters location. The new building is connected to the company’s LAN via fiber-optic cable. Multiple users in the new building are unable to access the company’s intranet site via their web browser, but they are able to access internet sites. Which of the following describes how the network administrator can resolve this issue?
Correct Answer:
A
If multiple users in a new building are unable to access the company’s intranet site via their web browser but are able to access internet sites, the network administrator can resolve this issue by correcting the DNS server entries in the DHCP scope. The DHCP scope is responsible for assigning IP addresses and DNS server addresses to clients. If the DNS server entries are incorrect, clients will not be able to access intranet sites.

A company wants to implement a large number of WAPs throughout its building and allow users to be able to move around the building without dropping their connections Which of the following pieces of equipment would be able to handle this requirement?
Correct Answer:
C
A wireless controller would be able to handle the requirement of implementing a large number of WAPs throughout the building and allowing users to move around without dropping their connections. A wireless controller is a device that centrally manages and configures multiple wireless access points (WAPs) on a network. It can provide features such as load balancing, roaming, security, QoS, and monitoring for the wireless network. A wireless controller can also support wireless mesh networks, where some WAPs act as relays for other WAPs to extend the wireless coverage. References:
