A.    LDP is automatically enabled globally on all interfaces, when ip cef is enabled globally. B.    LDP is enabled on each interface, using the mpls ip interface configuration command. C.    LDP is enabled on each interface, using the interface command under mpls ldp (MPLS LDP configuration mode). D.    LDP is enabled globally on all interfaces, using the mpls ldp global configuration command. E.    LDP is enabled globally on all interfaces, using the mpls ip global configuration command.Answer: C QUESTION 32 Which four statements about REP configurations on a Cisco ME 3400 switch port are true? (Choose four.) A.    The port must be an NNI type and must be in trunk mode. B.    Use the rep segment number command to enable REP on the switch port. C.    A REP segment cannot be wrapped into a ring topology. REP supports only a topology where each REP segment has two exit points via two edge switches. D.    The port where the segment terminates is called the edge port. E.    With REP, at least one port is always blocked in any given segment-that is, the alternate port. F.    If a failure occurs within the segment, the blocked port goes to the forwarding state after it goes through the listening state and the learning state. Answer: ABDE QUESTION 33 A VLAN is a logical grouping of switch ports that belong to which two of these? (Choose two.) A.    the same virtual switch cluster B.    the same IP subnet C.    the same collision domain D.    the same broadcast domain E.    the same virtual routing and forwarding instance Answer: BD QUESTION 34 Refer to the exhibit. Which statement is true?    A.    VLAN 1 traffic is sent untagged on the fa0/11 trunk port. B.    All VLANs traffic, including the native VLAN traffic, is tagged with a VLAN ID when it is sent over the fa0/11 trunk port. C.    The switchport trunk allowed vlan command is not configured; therefore, no VLANs are allowed on the trunk. D.    The encapsulation type that is used is 802.1ad. E.    The switchport trunk native vlan command is not configured; therefore, the trunk is not operational. Answer: A QUESTION 35 Refer to the partial configurations exhibit. What additional configurations are required to enable inter-VLAN routing for VLANs 10 and 20 on the Cisco ME 3400 switch using the metro IP access image?    A.    interface Fa0/1 ip address 192.168.10.1 255.255.255.0 ! interface Fa0/2 ip address 192.168.20.1 255.255.255.0 !
