Q17. What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU?
A. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives an 802.1d BPDU, it responds with an 802.1d BPDU and eventually the two switches run 802.1d to communicate.
B. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it responds with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
C. 802.1d does not understand RSTP BPDUs because they are different versions, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU.
D. 802.1d understands RSTP BPDUs because they are the same version, but when a RSTP switch receives a 802.1d BPDU, it does not respond with a 802.1d BPDU and eventually the two switches run 802.1d to communicate.
Answer: A
Q18. Refer to the exhibit.
What is the result of the SPAN configuration on a Cisco switch?
A. Configure a SPAN session to monitor the received traffic on interface g0/4 only for VLAN 3.
B. Configure a SPAN session to monitor the received traffic on interface g0/4 for all VLANs except VLAN 3.
C. Configure a SPAN session to monitor the received traffic on interface g0/5 only for VLAN 3.
D. Configure a SPAN session to monitor the received traffic on interface g0/5 for all VLANs except VLAN 3.
Answer: A
Q19. A network engineer configured a fault-tolerance link on Gigabit Ethernet links G0/1, G0/2, G0/3, and G0/4 between two switches using Ethernet port-channel. Which action allows interface G0/1 to always actively forward traffic in the port-channel?
A. Configure G0/1 as half duplex and G0/2 as full duplex.
B. Configure LACP port-priority on G0/1 to 1.
C. Configure LACP port-priority on G0/1 to 65535.
D. LACP traffic goes through G0/4 because it is the highest interface ID.
