QUESTION NO: 1
As shown in the figure, Between R1 and R2 are PPP links and the direct connection ports are not on the same network segment, but the R1 and R2 direct connection ports can communicate, and the Ethernet link cannot communicate under the same IP planning, what are the reasons? (Multiple Choice)

A. R1 and R2 are connected to the POS port, and the 32-bit host route of the direct connection port of the other party is learned through IPCP. B. R1 and R2 are connected to the POS port and learns the MAC address of the peer interface through LCP, and does not require the ARP request MAC address. C. The data packets of the interconnected POS interface of R1 and R2 do not need to encapsulate the Ethernet header, and do not need to use ARP to request the MAC address. D. R1 and R2 are connected to the POS port, and the 24-bit subnet route of the direct connection port of the other party is learned through IPCP.

Correct Answer: A,C

QUESTION NO: 2
In the following topology picture, R1 can access the Internet through R2 and R3. R1 and R2, and R1 and R3 establish an EBGP connection. R2 and R3 belong to the same AS. The default route is advertised through BGP. R2 is the optimization when requiring R1 to access the Internet traffic. The following practices that can be achieved are (Multiple Choice)

A. R1 specifies that the peer R2 sets the local priority to 150 in the import direction. B. R2 specifies that the peer R1 sets the MED attribute to 150 in the export direction. C. R2 specifies that the peer R1 sets the local priority to 150 in the export direction. D. R1 specifies that the peer R3 sets the MED attribute to 150 in the import direction.

Correct Answer: A,D

Correct Answer: B

QUESTION NO: 5
Which of the following options is correct for the description of the optimal routing elections for various protocols?

A. OSPF puts all routing information in the LSDP into the IP routing table. B. Different routing entries learning from BGP and OSPF to the same destination network segment select the optimal route to join the IP routing table by comparing the preference value of the protocol. C. BGP selects the optimal route to the same destination network segment by comparing the cost value of the route entry. D. The route with the next hop unreachable in BGP is also put into the IP routing table.

Correct Answer: B
