A.PAT
B.802.1Q
C.Spanning-tree
D.VLANs
E.QoS

A.Voice VLANs are only used when connecting an IP phone and a host to distinct switch ports
B.Access ports that are configured with voice VLANs will always trust the CoS that is received from IP phones
C.Access ports that are configured with voice VLANs may or may not override the CoS value that is received from an IP phone
D.Voice VLANs are configured using the switchport voice vlan vlan-ID interface configuration command
E.Voice VLANs provide a trunking interface between an IP phone and an access port on a switch to allow traffic from multiple devices that are connected to the port
F.Enabling Voice VLAN on a switch port will automatically configure the port to trust the incoming CoS markings

A.Effectively the trust boundary has been moved to the IP phone.
B.RTP will be used to negotiate aCoS value based upon bandwidth utilization on the link.
C.The switch is rewriting packets it receives from the IP phone and determining theCoS value.  
D.The switch will no longer tag incoming voice packets and will trust the distribution layer switch  to set theCoS.
E.The host is now establishing theCoS value and has effectively become the trust boundary.

A. The route to 224.69.15.0/24 will be out Ethernet 0
B. The reverse path forwarding (RPF) for the route 224.2.0.1 failed to find the interface on which the multicast packet was rece ived
C. Multicast route to 224.69.15.0/24 was added to the mroute table and created by a source directly connected to the router
D. Multicast route to 10.16.0.0/16 was added to the mroute table and created by a source directly connected to the router
E. This router received an IGMP host report from a group member or a PIM join message

A. R1 and R4
B. R2 and R3
C. ip summary-address eigrp 1 10.1.1.0 255.255.255.0 and ip summary - address eigrp 110.2.2.0 255.255.255.0
D. variance 2
E. eigrp stub connected
F. no auto - summary

A.The show ip eigrp neighbors command on R1 lists the revised Hello timer
B.The show ip eigrp interfaces command on R1 lists the revised Hello timer
C.The R1 - R2 neighborship fails due to Hello timer mismatcH
D.The show ip eigrp interfaces detail command on R1 lists the revised Hello timer
