The two routers of the customer are connected back to back by V.35 cables, and one of the routers has the following interface information: [MSR-Serial0/0]display interface Serial 0/0
Serial0/0 current state: UP
Line protocol current state: UP
Description: Serial6/0 Interface
The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
Internet Address is 6.6.6.1/30 Primary
Link layer protocol is PPP
LCP opened, IPCP opened
From the above information, you can know ______. (Multiple choice)

• A. You can already ping the peer's address on this router. 6.6.6.2 It is impossible to judge whether the verification is passed, so the peer's address may not be able to ping
• B. This router has completed PPP negotiation with the remote device, and successfully established a PPP link
• C. The PPP PAP or CHAP verification option has been successfully completed between this router and the remote device. It is impossible to see in the question whether there is verification and whether it has passed
• D. The interface information prompts, the second IP address subordinate can also be configured under this interface

A network connection is like:
HostA----GE0/0--MSR-1--S1/0------S1/0--MSR-2--GE0/0----HostB
Among them, the two empty-configured MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GE0/0 interfaces are respectively connected to the client hosts HostA and HostB. All physical connections are normal.
Now add the following configuration under the S1/0 interface of MSR-2:
interface Serial1/0
link-protocol ppp
ppp pap local-user 123 password simple 456
ip address 6.6.6.1 255.255.255.0
So ______ . (Multiple choice)

• A. If only PPP encapsulation and IP address 6.6.6.2/24 are configured on the S1/0 interface of MSR-1, it cannot communicate
• B. Only need to configure PPP encapsulation and IP address 6.6.6.2/24 on the S1/0 interface of MSR-1 to communicate with each other
• C. When performing PAP verification, MSR-2 will first send the password 456 to MSR-1 in clear text
• D. When performing PAP verification, MSR-2 will first send username 123 and password 456 to MSR-1

To view the debug information of NAT packets, you should use the ______ command to turn on the debug information and output it to the display.

• A. terminal debugging debugging nat
• B. terminal monitor terminal debugging debugging nat packet
• C. terminal monitor terminal debugging debug nat
• D. terminal monitor debugging nat

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

• A. Users are not restricted by physical devices, VLAN users can be anywhere in the network
• B. Enhance the robustness of the network
• C. Create a virtual working group
• D. Enhance the security of communication
• E. Limit broadcast packets and improve bandwidth utilization
• F. Reduce the cost of movement and change

On the MSR router, if you want to modify some configuration after logging in to the device at the access level, you can use the ______ command to switch to level 3. (Multiple choice)

• A. login
• B. super
• C. password
• D. level 3
