QUESTION 46
As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1) entry on RTB?

QUESTION 48
About the merits and demerits of inter-AS VPN-IPv4 Option B using MP-EBGP between ASBRs, which statement is true?

The inter-AS scheme in Option B is an inherent feature of VPN.

VRFs matching PEs must be configured on the ASBR.

An ASBR is required to store all VPN routes, which challenges the performance of the ASBR.

An ASBR does not store VPN routes but sends them out as label data.

QUESTION 49
On a metropolitan area network, VIP customers access the network through the MPLS VPN to ensure their security. Which of the following security deployments are required for PEs?

Configure the CP-CAR on the interface connected to the CE.

Deploy protocol authentication if a router protocol is used between PEs and CEs.

Configure the ACL to filter out data packets with common network viruses at the interface connected to the CE.

Configure the ACL to filter out IP packets that use the IP address of the CE-connected interface as the destination address.

QUESTION 50
Refer to the exhibit.

As shown in the figure, PE 1 sets up an MP-IBGP neighbor relationship
with PE 2 and they communicate over MPLS LDP. A CE communicates with a PE over OSPF.
Configure the VRF on PE 1 as follows:
ip vpn-instance vrf1
route-distinguisher 100:1
vpn-target 1:1 export-extcommunity
vpn-target 1:1 import-extcommunityConfigure OSPF on PE 1 as follows:
ospf 1 vpn-instance vrf1
area 0.0.0.0
network 100.1.1.0 0.0.0.255
Configure BGP on PE 1 as follows:
bgp 100
peer 22.22.22.22 as-number 100
peer 22.22.22.22 connect-interface LoopBack0
#
ipv4-family unicast
undo synchronization
peer 22.22.22.22 enable
#
ipv4-family vpnv4
policy vpn-target
peer 22.22.22.22 enable
#
ipv4-family vpn-instance vrf1
import-route ospf 1
PE 2 has the same configurations as PE 1. MP-IBGP neighbor relationships have been set up between PEs, and OSPF neighbor relationships have been set up between PEs and CEs. A valid route 1.1.1.1/32 is imported from CE 1 to an OSPF area, but CE 1 does not learn the route. What is the reason?

CE cannot be connected to a PE through OSPF.

CE can be connected to a PE through OSPF only when the PE also runs OSPF.

An RD is shared by VRFs on PE 1 and PE 2.

BGP routes must be imported to OSPF areas on a PE.

QUESTION 51
Exhibit:

Labels are retained using the liberal label retention method.

A VC must be established using remote LDP.

QUESTION 53
Which of the following statements about control words in the L2VPN are true?

the VC may not become Up

The control word can be used to identically the packet sequence.

A control word generally has two bytes and can ne extended to four bytes.

and the AC uses Peer-to-protocol (PPP), control words can be used to transfer and identify PPP packet
with a bytes.

QUESTION 58
Which of the following statements about the MAC address learning in VPLS are true? (ACD)

The PE learns the MAC address of a directly connected CE through the attachment circuit (AC) and learns the MAC address of a remote CE through the pseudo wire (PW).

The PE learns the MAC address of a directly connected CE through the PW and learns the MAC address of a remote CE through the AC.

In qualified mode, the PE learns MAC addresses on a per-VLAN basis in each virtual switch instance (VSI). Each user VLAN has its own broadcast domain and independent MAC address space.

In unqualified mode, the PE learns MAC addresses on a per-VSI basis and all user VLANs share a broadcast domain and a MAC address space.

Only one EXP value may be contained, and the value is uncertain.

Only two EXP values may be contained, and the values are uncertain.
