NEW QUESTION 210
To modify the device name, you should use the ______ command (please write the full command).

NEW QUESTION 211
It is found in the routing table of an MSR 30 router that the cost value of the route to the destination network segment 61.232.200.253/22 is 16, so the correct description of this route entry is ______. (Multiple choice)

If the route is learned through the RIP protocol, then the route may be in a suppressed state

The route may be a static route

If the route is learned through the RIP protocol, it is possible that the network 61.232.200.253/22 is malfunctioning

The route can only be a dynamic route

NEW QUESTION 212
Two empty-configured MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their respective S1/0 interfaces, and their respective GigabitEthernet0/0 interfaces
Connect the client hosts HostA and HostB respectively:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
Then make the following configuration on the two routers:
Configuration on MSR-1:
[MSR-1]interface GigabitEthernet 0/0
[MSR-1-GigabitEthernet0/0]ip add 192.168.1.1 24
[MSR-1]interface Serial 1/0
[MSR-1-Serial1/0]ip address 30.3.3.1 30
[MSR-1]rip
[MSR-1-rip-1]network 0.0.0.0
Configuration on MSR-2:
[MSR-2]interface GigabitEthernet 0/0
[MSR-2-GigabitEthernet0/0] ip address 10.10.10.1 24
[MSR-2]interface Serial 1/0
[MSR-2-Serial1/0]ip address 30.3.3.2 30
[MSR-2]rip
[MSR-2-rip-1]network 10.10.10.0
[MSR-2-rip-1]network 30.3.3.1
According to the above configuration, the WAN interface between the two routers can communicate with each other, other physical links in the network are good, and the two hosts HostA,
HostB can ping the address of their gateway GigabitEthernet0/0, so the following statement is correct _____.

The command network 0.0.0.0 on MSR-1 is configured incorrectly, and the specific network segment should be configured

There is no RIP route in the routing table of MSR-2

The command network 30.3.3.1 on MSR-2 is configured incorrectly, it should be network 30.3.3.2

The above three items are all wrong, the two routers can learn RIP routing

NEW QUESTION 213
The MAC address table on a layer 2 switch is shown in the figure.

When the switch receives a broadcast frame from the E1/0/1 interface, it will ______ the frame. (Multiple choice)

Send out from the E1/0/1 interface

Send out from the E1/0/2 interface

Send out from the E1/0/3 interface

send out from E1/0/4 interface

send out from all interfaces on the switch

Discard directly

NEW QUESTION 214
The number of available host addresses contained in the natural classification network segment corresponding to the IP address 165.110.20.67 is. (Please fill in Arabic numerals)

NEW QUESTION 215
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?

This route must be learned through dynamic routing

The priority of this route is the highest value, which means any route from an untrusted source

Cost 20 means that the hop count of the route is 20

This is an effective dynamic route

NEW QUESTION 216
Compared with traditional LAN, which of the following advantages does VLAN have? (multiple choice)

Reduce the cost of movement and change

Create a virtual working group

Users are not restricted by physical devices, VLAN users can be anywhere in the network

Limit broadcast packets and improve bandwidth utilization

Enhance the security of communication

Enhance the robustness of the network

NEW QUESTION 217
Among the STP port states listed below, which are unstable intermediate states? (multiple choice)

Blocking

Listening

Learning

Forwarding

Disabled

NEW QUESTION 218
The basic process of Layer 2 forwarding of an Ethernet switch includes ______.

Add or refresh MAC address table entries according to the source MAC address and VLAN ID information of the received Ethernet frame;

Search the MAC address table according to the destination MAC address, if no match is found, then broadcast in the VLAN corresponding to the message;

If a match is found, but the port corresponding to the entry does not belong to the VLAN corresponding to the packet, then the frame is discarded;

If a match is found and the port corresponding to the entry belongs to the VLAN corresponding to the packet, then the packet is forwarded to that port, but if the port corresponding to the entry is the same as the port that received the Ethernet frame, the packet is discarded. frame

local domain name server

Primary domain name server

Root DNS

Authorized domain name server
