After the implementation of several different types of switches from different vendors, a network
engineer notices that directly connected devices that use Cisco Discovery Protocol are not visible.
Which vendor-neutral protocol could be used to resolve this issue?

Several new switches have been added to the existing network as VTP clients. All of the new
switches have been configured with the same VTP domain, password, and version. However,
VLANs are not passing from the VTP server (existing network) to the VTP clients. What must be
done to fix this?

After implementing VTP, the extended VLANs are not being propagated to other VTP switches.
What should be configured for extended VLANs?

Refer to the exhibit.

Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C
receives VLAN information from the VTP server Switch A, but Switch B does not receive any
VLAN information. What is the most probable cause of this behavior?

Refer to the exhibit.

Switch A, B, and C are trunked together and have been properly configured for VTP. Switch B has
all VLANs, but Switch C is not receiving traffic from certain VLANs. What would cause this issue?

After the recent upgrade of the switching infrastructure, the network engineer notices that the port
roles that were once “blocking” are now defined as “alternate” and “backup.” What is the reason
for this change?

An administrator recently configured all ports for rapid transition using PortFast. After testing, it
has been determined that several ports are not transitioning as they should. What is the reason for
this?

Which technique automatically limits VLAN traffic to only the switches that require it?

What effect does the mac address-table aging-time 180 command have on the MAC addresstable?

While working in the core network building, a technician accidently bumps the fiber connection
between two core switches and damages one of the pairs of fiber. As designed, the link was
placed into a non-forwarding state due to a fault with UDLD. After the damaged cable was
replaced, the link did not recover. What solution allows the network switch to automatically recover
from such an issue?
