1. The two empty-configured MSR routers MSR-1 and MSR-2 are directly connected through their respective GE0/0 interfaces, and the IP addresses on GE0/0 of MSR-1 and MSR-2 are 10.1.1.1/24 and 10.1.1.2. /24, there is IP reachability between two GE0/0 interfaces.
Then added the following OSPF configurations on the two routers:
MSR-1:
[MSR-1-ospf-1] area 0.0.0.255
[MSR-1-ospf-1-area-0.0.0.255] network 10.1.1.0 0.0.0.255
MSR-2:
[MSR-2-ospf-1] area 255
[MSR-2-ospf-1-area-0.0.0.255] network 10.1.1.0 0.255.255.255
Then the correct description of the above configuration is _____. (Multiple choice)
A) The OSPF interfaces of the two routers belong to the OSPF area 255
B) The OSPF interfaces of the two routers do not belong to the same OSPF area, and the OSPF Area of one of the routers is incorrectly configured
C) The command network 10.1.1.0 0.0.0.255 on MSR-1 means to start OSPF on the GE0/0 interface of the router and join the corresponding area
D) The command network 10.1.1.0 0.255.255.255 on MSR-2 cannot start OSPF on the GE0/0 interface of the router
2. When viewing the configuration, if there are many configuration commands and one screen cannot be displayed completely, after displaying one screen, you can press ___ to display the next page.
A) <Space> key
B) <Ctrl+c> key
C) <Ctrl+p> key
D) <Enter> key
3. A company needs to connect to the WAN to form a corporate network, and the bandwidth of the connection is required to be greater than 1Mbps. Which of the following interfaces and protocols are available?
A) PRI interface and cable, bundle multiple time slots, use PPP as the link layer protocol
B) V.35 protocol interface and cable, using Frame Relay as the link layer protocol
C) BRI interface and cable, bundling multiple time slots, using PPP as the link layer protocol.
D) V.35 protocol interface and cable, using PPP as the link layer protocol
4. The IP address 112.1.1.1 corresponds to the network address of the natural classification network segment.
5. The IP address of private network device A is 192.168.1.1/24, and its corresponding public network IP is 2.2.2.1;
The IP address of public network device B is 2.2.2.5. Now that device A is required to provide Telnet service to the public network, which of the following configurations can be used on the NAT device?
A) acl number 2000 rule 0 permit source 192.168.1.1 0.0.0.255 nat address-group 1 2.2.2.1 interface Ethernet 0/1 nat outbound 2000 address-group 1 no-pat
B) nat server protocol tcp global 2.2.2.1 telnet inside 192.168.1.1
C) nat server protocol telnet global 2.2.2.1 inside 192.168.1.1
D) acl number 2000 rule 0 permit source 192.168.1.1 0.0.0.255 nat address-group 1 2.2.2.1 interface Ethernet 0/1 nat outbound 2000 address-group 1
E) nat server protocol tcp global 2.2.2.1 23 inside 192.168.1.1 23
