질문 # 132
An enterprise has deployed a Huawei WLAN, but some STAs cannot associate with wireless signals. To troubleshoot this issue, you log in to the WAC and run related commands. The command output is as follows.
According to the command output, which of the following is the possible cause of the STA association failure?
정답：A
설명：
The command output in the exhibit shows that both AP radios are enabled, so a disabled radio is not supported by the evidence. The 5 GHz radio has relatively low channel utilization, while the 2.4 GHz radio reports channel utilization of approximately 90 percent. Such a high utilization value indicates that the air interface is heavily occupied by transmissions or interference. Huawei WLAN troubleshooting guidance identifies a busy air interface and a heavily loaded AP as possible causes of STA association failures because management and authentication frames may be delayed or lost when contention is severe. The displayed radio information alone does not prove that the affected STAs are in a blacklist or absent from a whitelist; those conditions require separate STA or VAP access-control information. Therefore, option A is the only choice directly supported by the command output. The correct troubleshooting interpretation is that excessive channel utilization on the radio can make the air interface busy and prevent some STAs from completing association successfully. The verified answer is A.
질문 # 133
During WLAN deployment, a Fit AP fails to go online on the WAC. Which of the following commands can you run on the WAC to locate the fault? (Choose all that apply.)
정답：A,D
설명：
When a Fit AP fails to go online, the WAC troubleshooting focuses on AP registration and onboarding status. The command display ap all shows the AP status and helps identify whether the AP is offline or not registered. The command display ap online-fail-record all provides detailed failure reasons for APs that failed to go online, which is directly used for fault location.
Commands related to VAP and SSID profiles are used for WLAN service configuration verification and do not help in diagnosing AP onboarding failures.
질문 # 134
If a network device has both a static route and a direct route to network 10.1.1.0/24, it uses the direct route preferentially.
정답：B
설명：
This statement is true . When a device has multiple routes to the same destination prefix, route selection is based first on the longest prefix match , and when prefix length is the same, the device compares the route preference or administrative priority associated with each routing source. On Huawei devices, a direct route has a better preference than a static route , so the direct route is selected first when both routes have the same destination and mask.
A direct route is generated automatically when an IP address is configured on an interface and that interface is Up. Because the destination network is directly connected, this route is considered more trustworthy and efficient than a manually configured static route pointing to the same prefix. HCIA-Datacom uses this principle to explain route selection, routing-table generation, and troubleshooting cases where a configured static route does not appear as the active route because a direct or dynamic route has higher priority. This is a basic but important concept in IP forwarding and helps engineers correctly interpret routing tables on Huawei routers and Layer 3 switches.
질문 # 135
In the figure, a TCP connection has been established between PC1 and PC2. After PC1 sends a data segment to PC2, which of the following is the acknowledgment number in the packet returned by PC2?
정답：B
설명：
In TCP, the acknowledgment number indicates the next byte that the receiver expects to receive. In the figure, PC1 sends a TCP segment to PC2 with sequence number = a+22 and payload length = 22 bytes .
Since TCP sequence numbers count bytes, the last byte carried in this segment corresponds to sequence number a+43 . Therefore, after PC2 successfully receives this data, it sends back an ACK indicating that the next expected byte is a+44 .
That is why option B is correct. This is a standard TCP reliability mechanism. TCP does not acknowledge
"packets" as units; it acknowledges the byte stream. The ACK number always points to the next byte expected from the peer. The source and destination port numbers identify the session, but the sequence and acknowledgment numbers track ordered delivery. HCIA-Datacom uses this mechanism to explain connection- oriented transport, reliable delivery, retransmission, and traffic control. Understanding how the payload length affects sequence progression is essential when analyzing packet captures and troubleshooting TCP communication problems in enterprise networks.
질문 # 136
The following ACL is configured on R1:
[R1] acl 2001
[R1-acl4-bask-2001] rule permit source 192.168.1.3 0
[R1-acl4-bask-2001] rule deny source 192.168.1.3 0
[R1-acl4-bask-2001] quit
If R1 matches packets against ACL rules in ascending order of rule IDs, hosts at 192.168.1.3/24 match the permit rule of the ACL.
정답：B
설명：
ACL rules are matched strictly in ascending order of rule IDs. However, in this ACL, rule 10 (deny) comes before rule 5 (permit) because rule IDs are not necessarily evaluated by statement order unless explicitly defined otherwise in behavior. Since rule IDs define processing order, the deny rule for 192.168.1.3 is evaluated first and matches the traffic, blocking it before it can reach the permit rule. Therefore, hosts at 192.168.1.3/24 do not match the permit rule, making the statement false.
