A. Router ACLs can be applied to the input and output directions of a VLAN interface.
B. Bridged ACLs can be applied to the input and output directions of a VLAN interface.
C. Only router ACLs can be applied to a VLAN interface.
D. VLAN maps and router ACLs can be used in combination.
E. VLAN maps can be applied to a VLAN interface

A. Issue the mls qos trust cos command on the switch port connected to the IP phone.
B. Issue the switchport priority extend cos command on the switch port connected to the IP phone.
C. Issue the switchport priority extend cos command on the IP phone.
D. Issue the mls qos trust cos command on the IP phone.

A.It disables the trust boundary feature because the switch knows a Cisco IP phone is attached.
B.The switch assigns a CoS value of 5 to incoming packets.
C.If a Cisco IP phone is attached and removed， the switch continues to trust the CoS values as  long as the switch is not rebooted.
D.It turns on STP to see if a Cisco IP phone is attached.
E.If a Cisco IP phone is attached， the switch trusts the CoS.
F.None of the other alternatives apply.

A. Spanning Tree Protocol （STP）
B. Delay reduction
C. Hot Standby Routing Protocol （HSRP）
D. Dynamic routing protocols
E. Quality of Service （QoS）
F. Jitter management

A.The "valid cached adjacency" entry indicates that CEF will put all packets going to such an adjacency to the next best switching mode.
B.The number 003071506800 is the MAC address of the source IP address.
C.There is a valid CEF entry for the destination network 192.168.150.0.
D.The number 003071506800 is the MAC address of the 192.168.199.3 next hop IP address.
E.The counters （0 packets， 0 bytes） indicate a problem with the 192.168.199.3 next hop IP address.
F.There is an adjacency for the 192.168.199.3 next hop IP address.

A. physical layer issues
B. no spanning tree loops
C. use of non-default HSRP timers
D. failure to set the command standby 35 preempt

A.IP traffic matching access list is forwarded through VLANs 5-10.
B.All VLAN traffic in VLANs 5-10 that match access list will be forwarded， and all else will be dropped.
C.IP traffic matching VLAN list 5-10 will be forwarded， and all other traffic will be dropped.
D.All VLAN traffic matching VLAN list 5-10 will be forwarded， and all traffic matching access list is dropped.
E.None of the other alternatives apply

A.Switch（config）#spanning-tree loopguard default
B.Switch（config-if）#spanning-tree bdpufilter
C.Switch（config）#udld aggressive
D.Switch（config-if）#spanning-tree bpduguard

A. Ports in VLAN 5
B. Utilization
C. VLAN information on port 0/5
D. Filters
E. MTU and type

A. Information will be carried in the RSTP BPDUs.
B. It will be propagated in VTP updates.
C. Information stored in the Forwarding Information Base and the switch will reply on query.  
D. Multiple Spanning Tree must be manually configured on the appropriate switches.
