List of questions
Question 201
What are two functions of a Layer 2 switch? (Choose two)
acts as a central point for association and authentication servers
selects the best route between networks on a WAN
moves packets within a VLAN
moves packets between different VLANs
makes forwarding decisions based on the MAC address of a packet
Question 202
Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?
BPDUfilter
PortFast
Backbonefast
BPDUguard
PortFast
Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast isn't enabled, DHCP timeouts can occur while STP converges, causing more problems.
