AThe total number of instances that enable the IPv6 address family in the VPN configured on this side is 1 .

BVPN-Instance vpna does not receive VPN routes with an RT of 2:1.

CThe GigabitEthernet 1/0/0 interface is tied to the VPN-Instance vpna

DThe device assigns a label to each route of the VPN-Instance vpna.

Answer : A, D

Question 2

As shown in the FIGURE, in the HUB & Spoke networking mode of MPLS BGPVPN, in order to achieve the division, it can only communicate with the headquarters. Divisions cannot communicate with each other, and the settings for RT can be which of the following scenarios? (Multiple choice questions).

A??:Import Target: 123; Export Target:123 ?? 1: lmport Target:123; Export Target:123 ?? 2:lmport Target: 12: 3; Export Target: 123

B??: Ilmport Target: 1:1l; Export Target: 3:3 ?? 1: Import Target: 33; Export Target: 1.1 ?? 2:lmport Target: 3:3; ExportTarget: 2

C??: lmport Target: 22; Export Target: 33 ?? 1: lmport Target: 33; Export Target: 1:1 ?? 2:lImport Target: 33; Export Target: 2

D??: lmport Target:123; Export Target: 3:12 ?? 1:Import Target: 312; Export Target:123 ?? 2:Import Target: 3:12; Export Target: 12:3

Answer : D

Question 3

What is the correct description of the scene shown in the following figure?

AR1 simultaneously exists level-1 and Level-2 LSDB

BR1 can ping the interface address of R2 loopback 0

CR1 has a route to R2 loopback 010022/32

DThere is no neighbor relationship between R1 and R2

Answer : A, C

Question 4

There are routers as follows, according to which the compromise conclusion is wrong?

AR3 must be the DIS of some Level-1 link

BThe R3 router is a Level-1-2 router

CR3 must be the DIS of some Level-2 link

DThe system ID of the R3 router is 000300000000

Answer : A

Question 5

As shown in the figure, the PPP link between R1 and R2 is not in the same network segment, but the R1 and R2 direct connectors can communicate, and the Ethernet link cannot communicate under the same planning, why?

AThe interconnect POS ports of R1 and R2 learn the 24-bit subnet route of each other's direct connection ports through IPCP

BThe interconnect POS ports of R1 and R2 learn the 32-bit host route for each other's direct connections through IPCP

CThe interconnect POS port of RI and R2, through LCP learns the MAC address of the opposite termination , does not need to use ARP to request the MAC address

DThe data packets of the interconnect POS ports of R1 and R2 do not need to encapsulate ethernet headers and do not need to use ARP to request MAC addresses

Answer : B, D

Question 6

The following statement about IPSec VPN is correct ?qo

ATwo routers establish an IPSec VPN in brutal mode, so that the two devices can interact with a minimum of 4 messages to establish a tunnel.

BBrutal mode can support NAT traversal, while main mode does not support NAT traversal.

CThe two routers can establish OSPF neighbor relations and exchange intranet routes through the IPSec VPN tunnel

DThe two routers establish IPSecVPN in main mode, and from the 5th packet (included), the payload's data will be encrypted.

Answer : D

Question 7

As shown in the figure,

all interfaces of the router have OSPF turned on, and the COST value of the link is identified in the figure. R2's loop backO interface advertises a cost in region l, then R1 reaches 10022/32 The value is

See Below Explanation:
