A. 0
B. 1
C. 2
D. 3

正解：B

質問 # 122
The CPU was attacked by malicious traffic. Here are some of the following ways to prevent an attack:
Multi-select

A. Turn off the remote login function of the router.
B. USE CPCAR to rate limit messages sent up to the CPU according to the protocol type
C. Speed limiting of messages sent to the CPu on the soil.
D. Analyze and count the packets sent to the CPU to find out the user of the attack source or the interface of the attack source.
E. Filter packets with AcL on the compromised router port

正解：A、E

質問 # 123
NSF (Non-StoppingForwarding) and non-stop circuits are transmitted NSR (Non-Stopping Routing) are two highly reliable solutions, and the following statement is correct

A. NSR backers require the ability to support NSR through specific message negotiation
B. After NSR enablement, if the business batch backup has not yet ended, a master board failure occurs, the NSR cannot be completed
C. After NSF is enabled, the router is switched back, and the routing table and forwarding table remain unchanged, so traffic is not lost during grf time
D. NSF routers do not need to negotiate the ability to support NSF through specific messages

正解：B

質問 # 124
The Huawei SD-WAN solution has three types of channels. Drag the channel names to their corresponding callouts.

正解：

解説：

Explanation:
A white line with black lines AI-generated content may be incorrect.

In Huawei'sSD-WAN architecture, the following channels are defined:
Management Channel (Callout 1)
BetweeniMaster NCEandEdge devices.
Used for deviceregistration, configuration, and monitoring.
Encrypted with HTTPS.
Control Channel (Callout 2)
BetweenEdge devices and RR (Route Reflector).
Used forroute exchangeandcontrol signaling, typically overMPLS or Internet.
Data Channel (Callout 3)
BetweenEdge to Edge(e.g., HQ to branch).
Used for actualservice traffic transmission, carried overMPLS, Internet, or both.
Correct Mapping:
Management channel# Callout1(from iMaster NCE to Edge)
Control channel# Callout2(Edge to RR)
Data channel# Callout3(Edge to Edge, over MPLS/Internet)

質問 # 125
If the Interface Sticky MAC function is enabled, what is the number of MAC addresses that the interface learns by default?

A. 0
B. 1
C. 2
D. 3

正解：D
