What occurs when PortFast is enabled on an interface that is connected to another switch?

A.
Root port choice and spanning-tree recalculation are accelerated when a switch link goes down.
B. After spanning-tree converges, PortFast shuts down any port that receives BPDUs.
C. VTP is allowed to propagate VLAN configuration information from switch to switch automatically.
D. Spanning-tree fails to detect a switching loop increasing the likelihood of broadcast storms.

Correct Answer: D

Explanation:

Explanation:
Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states.
Note: To enable portfast on a trunk port you need the trunk keyword “spanning-tree portfast trunk”

What is the difference between IPv6 unicast and anycast addressing?

A.
An individual IPv6 unicast address is supported on a single interface on one node, but an IPv6 anycast address is assigned to a group of interfaces on multiple nodes.
B. IPv6 anycast nodes must be explicitly configured to recognize the anycast address, but IPv6 unicast nodes require no special configuration.
C. IPv6 unicast nodes must be explicitly configured to recognize the unicast address, but IPv6 anycast nodes require no special configuration.
