H3C Constructing Small - and Medium - Sized Enterprise Network Sample Questions:
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 command network 10.1.1.0 0.255.255.255 on MSR-2 cannot start OSPF on the GE0/0 interface of the router
B) 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
C) 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
D) The OSPF interfaces of the two routers belong to the OSPF area 255
2. DNS works on the ______ of the OSI reference model.
A) Session layer
B) Network layer
C) Transport layer
D) Application layer
3. Which of the following statements about CSMA/CD is correct is ______. (Multiple choice)
A) CSMA/CD is applied in bus-type Ethernet, mainly to solve the problem of how to detect conflicts and ensure orderly transmission of data when multiple stations send data at the same time.
B) If two stations start transmitting at the same time, they will hear the signal conflict and pause the frame transmission.
C) When a station connected to the Ethernet wants to transmit a frame, it must wait until the channel is free, that is, the carrier disappears.
D) The station can start transmitting its frame only when the channel is free.
4. There is a default route in the router's routing table, its destination network segment and mask are both 0.0.0.0, and its next hop is the router's S0/0 interface, then the following description of this route is correct. ______. (Multiple choice)
A) The route has the shortest mask, so the data packet will be forwarded according to the default route only if there is no other route matching the data packet
B) The priority of this route may be 100
C) The metric value of this route may be 3
D) When the router receives a data packet to the destination address 120.1.1.1, if there is no other exact match in the router table, then the data packet will match this default route
5. In subnet division, which part of the natural classification IP address is occupied by the subnet number?
A) host number part
B) Subnet number part
C) Network number part
D) None of the above is correct
