- B . OSPF
- C . RIPv1
- D . RIPv2
The two empty MSR routers are connected by the way shown in the figure. By configuring the IP address, the GE0 / 0 interfaces of the two routers can communicate with each other.
Now the following configurations are added to the two routers:
RTA:
[RTA]ospf
[RTA-ospf-1]area 0
[RTA-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTA-GigabitEthernet0/0]ospf dr-priority 2
DAF:
[RTB]ospf [RTB-ospf-1]area 0
[RTB-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3
[RTB-GigabitEthernet0/0]ospf dr-priority

- C . Of the two routers, one is DR and the other is DRother
- D . The neighbor status of the two routers is FULL and 2-Way
There is a default route in the router’s routing table, the destination network segment and mask are 0.0.0.0 , and the next hop is the router’s S0 / 0 interface, then the following description of this route is correct ______ . (Multiple choices)
- A . When the router receives a packet destined to the destination address 120.1.1.1 , if there is no other exact match in the router table, then the packet will match this default route
- B . The mask of this route is the shortest, so only when no other route matches the data packet, the data packet will be forwarded according to the default route.
- C . The metric of this route may be 3
- D . The priority of this route may be 100
There is a default route in the router’s routing table, the destination network segment and mask are 0.0.0.0 , and the next hop is the router’s S0 / 0 interface, then the following description of this route is correct ______ . (Multiple choices)
- A . When the router receives a packet destined to the destination address 120.1.1.1 , if there is no other exact match in the router table, then the packet will match this default route
- B . The mask of this route is the shortest, so only when no other route matches the data packet, the data packet will be forwarded according to the default route.
- C . The metric of this route may be 3
- D . The priority of this route may be 100
There is a default route in the router’s routing table, the destination network segment and mask are 0.0.0.0 , and the next hop is the router’s S0 / 0 interface, then the following description of this route is correct ______ . (Multiple choices)
- A . When the router receives a packet destined to the destination address 120.1.1.1 , if there is no other exact match in the router table, then the packet will match this default route
- B . The mask of this route is the shortest, so only when no other route matches the data packet, the data packet will be forwarded according to the default route.
- C . The metric of this route may be 3
- D . The priority of this route may be 100
0.0.0/8 Static 60 0 100.1.1.1 GE0/0
At this time, the router receives a data packet with a destination address of 6.6.6.6 , then ______ .
- A . The packet will preferentially match the RIP route in the routing table because its mask is the longest
- B . The data packet will preferentially match the RIP route in the routing table because its priority is high
- C . The packet will preferentially match the static route in the routing table, because its cost Cost is small
- D . The packet will preferentially match the static route in the routing table because its mask is the shortest
An empty configuration MSR router RTA is connected to two routers RTB and RTC running in OSPF Area 0 through GE0 / 0 and GE1 / 0 respectively . RTA interface GE0 / 0 and GE1 / 0 of the IP addresses are 192.168.3.2/24 and 192.168.4.2/24 . Add the following configuration on RTA :
[MSR-ospf-1] area 0.0.0.0
[MSR-ospf-1-area-0.0.0.0]network 192.168.0 0.0.3.255
[MSR-GigabitEthernet0/0]ospf cost 2
[MSR-GigabitEthernet1/0]ospf dr-priority 0

- A . This configuration MSR router the GE0 / 0 , GE1 / 0 on both started OSPF
- B . This configuration only MSR router GE0 / 0 interface launched OSPF
- C . RTA may become the DR of the network segment where the two GE interfaces are located
- D . RTA can only become the DR of the network segment where one of the GE interfaces is located
- E . modify the interface GE0 / 0 of Cost does not affect the OSPF adjacency establishment of
The client router’s interface GigabitEthernet0 / 0 is connected to the LAN host HostA , and its IP address is 192.168.0.2/24 ;
Interface Serial6 / 0 interface is connected to the far end and is currently operating normally. The ACL configuration is now added as follows:
firewall enable
firewall default permit
acl number 3003
rule 0 permit tcp
rule 5 permit icmp
acl number 2003
rule 0 deny source 192.168.0.0 0.0.0.255
interface GigabitEthernet0/0
firewall packet-filter 3003 inbound
firewall packet-filter 2003 outbound
ip address 192.168.0.1 255.255.255.0
interface Serial6/0
link-protocol ppp
ip address 6.6.6.2 255.255.255.0
Assuming that other related configurations are correct, then ______ . (Multiple choices)
- A . HostA cannot ping the two interface addresses on the router
- B . HostA can not ping through 6.6.6.2 , but can ping through 192.168.0.1
- C . HostA can not ping through 192.168.0.1 , but can ping through 6.6.6.2
- D . HostA can Telnet to the router
