在這個資訊時代，IT行業被很多人關注，但是在如今人才濟濟的社會裏任然比較缺乏IT人。很多公司都招聘IT人才，他們一般考察IT人才的能力會參考他們擁有的IT相關認證證書，所以擁有一些IT相關的認證證書是受很多公司歡迎的。但是這些認證證書也不是很容易就能拿到的。Huawei H12-891_V1.0 就是一個相當有難度的認證考試，雖然很多人報名參加Huawei H12-891_V1.0考試，但是通過率並不是很高。

問題 #237
During WLAN planning and design, channels 1, 6, and 11 are recommended on the 2.4 GHz frequency band, and channels 1, 5, 9, and 13 are recommended in high-density scenarios. On the 5 GHz frequency band, it is recommended thathigh-frequency and low-frequency channels of adjacent APs be staggered to prevent overlapping.
答案：B
解題說明：
On the2.4 GHzband, onlythree non-overlapping channelsexist:1, 6, and 11.
Inhigh-density WLAN scenarios, channels like1, 5, 9, and 13can be used withlower transmit powerto reduce co-channel interference - though they slightly overlap, they can work in dense deployments when managed properly.
On the5 GHzband, there are many non-overlapping channels. It's recommended tostagger high and low channelsamong adjacent APs toavoid interference.
Correct answer: A. TRUE

問題 #238
Which of the following statements about IPSG is incorrect?
答案：D
解題說明：
Comprehensive and Detailed
IP Source Guard (IPSG) is a Layer 3 security feature used to protect against IP address spoofing by filtering packets based on bound IP-MAC mappings.
Correct Statements:✔ IPSG is a Layer 3 filtering mechanism that checks if the source IP address of a packet matches the learned or configured bindings (Option B).✔ IPSG prevents unauthorized IP address changes by enforcing binding rules (Option C).✔ IPSG defends against IP spoofing attacks by dropping packets from unauthorized sources (Option D).
Incorrect Statement:❌ Option A is incorrect because IPSG does not send alarms to an NMS when an invalid packet is detected. Instead, it drops the packet.
Thus, the correct answer is A.

問題 #239
K company has two types of network services: UDP-based real-time video streaming services and TCP-based FTP download services. The company's network administrator often receives complaints that the FTP download speed is slow or unstable. What are the possible causes?
答案：C,D
解題說明：
Comprehensive and Detailed Explanation:
Key Factors Affecting FTP Performance:
Tail Drop and TCP Synchronization (A)#
Tail Dropcauses TCPglobal synchronization, reducing FTP speeds drastically when congestion occurs.
Since FTP isTCP-based, packet loss due to tail drop forcesTCP retransmissions, further degrading performance.
Priority Preemption by Video Traffic (D)#
UDP-based real-time video trafficis often prioritized overTCP-based trafficto avoid jitter and packet loss.
If video traffic hashigher QoS priority, FTP bandwidth may bepreempted, leading toslow speeds.
Incorrect Options:
#Option B:PQ scheduling typically prioritizes latency-sensitive traffic (VoIP), but this scenario does not mention priority queuing for FTP.
#Option C:No information about an explicitrate limiton FTP traffic.

問題 #240
Telemetry data must be encoded in GPB binary format. This format reduces the number of bytes in telemetry messages and improves the transmission efficiency compared with messages encoded in JSON format.
答案：A
解題說明：
Understanding Telemetry Encoding Formats
#What is Telemetry?
Telemetry is a real-time network monitoring methodthat provideshigh-frequency data collection.
Used inAI-driven networks for predictive analytics and automation.
#Common Telemetry Encoding Formats:
#GPB (Google Protocol Buffers)
Highly efficient binary formatthat reducesmessage size and CPU overhead.
Commonly used forhigh-speed, real-time analytics.
#JSON (JavaScript Object Notation)
Human-readable format, widely used inRESTful APIs.
Less efficientthan GPB in high-speed telemetry buteasier to debug.
#Why is the Answer FALSE?
#GPB is not mandatory; JSON can also be used in telemetry.
#Huawei supports both GPB and JSON telemetry encoding formats.
Real-World Application:
Cloud Networking:UsesGPB for fast data collectionandJSON for API-based telemetry visualization.
AI-Driven Networks:High-speedAI analyticsleverageGPB encodingfor efficiency.
