• A.Ethernet uses MAC address to identify host
• B.Usually only terminal hosts need MAC addresses, routers and other network devices do not need
• C.MAC address is a logical address that is easy to change
• D.The MAC address is solidified in ROM and cannot be changed under normal circumstances

A network administrator configured on a router
RIP: rip 1
version 2
network 100.0.0.0
network 8.0.0.0
However, it is found that the RIP route of the opposite end cannot be learned. The administrator needs to enable RIP debugging information on the router. Which of the following configurations can be used to view RIP debugging information on the router?

• A.<MSR>debugging rip 1 packet
• B.[MSR] debugging rip packet
• C.<MSR>debugging rip packet
• D.<MSR>debugging rip 2

In the router's routing table, there is an entry for a route with a network segment of 10.168.100.0/24, with a Cost of 20 and a Preference of 255, so which of the following statements about this route are correct?

• A.This route must be learned through dynamic routing
• B.This is an effective dynamic route
• C.The priority of this route is the highest value, which means any route from an untrusted source
• D.Cost 20 means that the hop count of the route is 20

The following statement about STP is correct. ______. (Multiple choice)

• A.STP information transfer is realized by transferring BPDUs between bridges running STP
• B.In a complex network, STP consumes a lot of processing resources, causing the network to fail to work normally.
• C.STP can activate the blocked redundant backup link to restore network connectivity when the current active path fails
• D.STP eliminates possible path loops in the network by blocking redundant links in the network

The MSR router exchanges routing information with the outside world through RIPv2. There are three routes 10.1.1.0/24, 10.1.2.0/24, 10.1.3.0/24 in the routing table, then the following RIP configuration is added to the router:
[MSR-rip-1] summary
Then the router will send out the route of which network segment as follows?

• A.10.1.0.0/22
• B.10.1.0.0/16
• C.10.1.2.0/22
• D.10.0.0.0/8
