As shown in the figure, RTA, RTB, RTC are interconnected over IS-IS, RTA, RTD, RTE, and RTC are interconnected over OSPF. Both IS-IS and OSPF use the default costs. RSVPTE is enabled on all routers and the interfaces between these routers. The Loopback0 interface of RTC is 192.168.0.3/32 and is advertised in both OSPF and ISIS areas. 192.168.0.3/32 is also the LSR ID of MPLS. Configurations of the MPLS and tunnel on RTA:

Which path will be selected when the tunnel becomes Up? What is the metric of this tunnel?

• A.  RTA-RTB-RTC; 1
• B.  RTA-RTD-RTE-RTC; 1
• C.  RTA-RTD-RTE-RTC; 3
• D.  RTA-RTB-RTC; 20

Which of the following statements about inter-AS VPN Option A are true? (ACE)

• A.  More logical links must be configured between ASBR-PEs when more VPNs are deployed.
• B.  The VPN instances on an ASBR-PE can be bound to both physical interfaces and logical interfaces.
• C.  ASBR-PEs communicate with each other through any multi-instance (PE-CE) capable routing protocol.
• D.  Option A provides excellent scalability and supports a great number of VPNs.
• E.  ASBR-PEs communicate with each other only through EBGP.

Exhibit:

As shown in the figure, complex traffic classification is configured for RTA's upstream GigabitEthernet 1/0/0. The QoS is configured as follows:

A tester sends TCP packets from GE 1/1 to GE 1/2 at 40 1.2.2 IF DSCP values of packets GE receives are not 46, what are the possible causes?

• A.  STC is disabled at RTA's GigabitEthernet 1/0/0.
• B.  The default mapping from the EF value to the DDCP value is modified
• C.  DSCP values of sent packets are not 10.
• D.  The qos phb command is enabled on RTA's GigabitEthernet1/0/0.

Exhibit:

Which of the following statements are false?

• A.  Ethernet 6/2/0 sends a state-refresh messages every 10 seconds
• B.  If the PIM-DM is enabled at Ethernet 6/2/0 on a router, the PIM-SM cannot be enabled at other interfaces on the router.
• C.  The TTL value is 60 in state-refresh messages sent by the router
• D.  Ethernet 6/2/0 sends a PIM hello message every 100 seconds.

Which of the following statements about the VPLS packet forwarding are true?

• A.  If the destination MAC address of a packet is not a broadcast address and a PE has not learned the MAC address, the broadcast this packet in one VSI
• B.  If the destination MAC address of a packets is not a broadcast address and a PE has not learned the MAC address, the PE broadcast this packet in on VSI.
• C.  If a receive broadcast packet sent a remote PE, it forwards the packet only to the AC interface instead of other PEs.
• D.  If a PE receives broadcast packets from a local user, the PE forwards the packets to all other interfaces In the same VSI and all other PEs.
