質問 # 22
(Multi-select) You queried PPPoE simulation results on the MDU side as shown below. From the query results, it can be judged that:
(Note: the actual simulation output is not included in the prompt.)
- A. The MDU management IP is configured correctly
- B. A, B, COn Huawei devices, PPPoE diagnostic/simulation tools verify the end-to-end PPPoE procedure (Discovery and Session), and-when credentials are supplied-authentication (PAP/CHAP) as well:
Successful PADI/PADO/PADR/PADS exchange confirms Layer-2 reachability to the BRAS (option C).
A successful session establishment and authentication indicate that the service configuration for PPPoE users is correct and the username/password & auth method are valid (options A and B).The MDU management IP (option D) is unrelated to the PPPoE access simulation itself; PPPoE runs over the subscriber VLAN/port/uplink toward BRAS, not via the MDU's management plane, so simulation success does not prove the management IP configuration.These behaviors align with Huawei's PPPoE diagnostic/monitoring command descriptions that detail session status, discovery phases, and authentication verification for fault location - C. The PPPoE user account and authentication method are correct
- D. The link between the MDU uplink and the BRAS is OK
- E. The service configuration of PPPoE users is normal
正解：A、B、C、D、E

質問 # 24
When the DHCP Option 82 function is enabled globally and in the VLAN service profile and the port/service- port is configured to allow user-side DHCP packets to carry Option 82, what is the processing policy if a user- side DHCP packet already containing Option 82 is received?
- A. The access device strips the Option 82 information from the user-side DHCP packet and forwards the packet.
- B. The access device directly forwards the user-side DHCP packet without any processing.
- C. The access device discards the user-side DHCP packet.
- D. The access device strips the Option 82 from the user-side DHCP packet and adds the local user information.
正解：D
解説：
In Huawei access network devices (such as MA5800, EA5800, and SmartAX series), the DHCP Option 82 (Relay Agent Information Option) feature is used to identify the source location of DHCP requests coming from users connected to access ports.
This helps the DHCP server assign IP addresses based on access topology information, such as slot, port, and VLAN IDs.
When Option 82 is enabled globally and within the VLAN service profile, and the port/service-port is configured to allow user-side packets to carry Option 82, the device processes incoming DHCP requests as follows:
* If a user-side DHCP packet does not contain Option 82:# The device automatically adds local Option
82 information (e.g., circuit ID, remote ID) before forwarding it to the DHCP server.
* If a user-side DHCP packet already contains Option 82:# The device removes (strips) the existing Option 82 field to prevent spoofing or inconsistent location data.# Then it adds its own local Option 82 information (accurate relay agent data based on the device's configuration).# The modified packet is then forwarded to the DHCP server.
This ensures that only trusted network-side Option 82 data is passed along, maintaining accurate user-location binding for IP address management and security.
Therefore, the correct behavior is:
The access device strips the Option 82 field from the user packet and adds its own local Option 82 information.

質問 # 25
Which of the following statements about multicast is incorrect?
- A. The report sent by a user is captured by the board logic and sent to the CPU of the board.
- B. You can add IGMP users to a BTV. By default, a multicast user can watch 8 programs.
- C. In the case of IGMP match mode disable, you need to configure a multicast channel.
- D. General parameters for multicast protocols (IGMP proxy and IGMP snooping) are configured globally at Layer 2 and apply to all multicast VLANs.
正解：C
質問 # 26
The ports in an OLT upstream protection group must be in the same protection group, and the same port cannot belong to different protection groups.
- A. TRUE
- B. FALSE
正解：A
解説：
For OLT uplink (NNI) protection groups (timedelay/weight, etc.), Huawei requires that each physical port belongs to one protection group only to avoid conflicting switchover control. A member port cannot be part of multiple protection groups simultaneously.

質問 # 27
(Radio) In the ACL, if you need to filter the packet according to the source IP address information, destination
IP address information, port number and other information of the packet, then the acl number template created
is
- A. 4000~4999
- B. 0
- C. 5000~5999
- D. 3000~3999
正解：D
質問 # 28
(Multiple choice) Which of the following measures can be adopted by GPON in terms of traffic control?
- A. T-CONT-CAR
- B. Flow-CAR
- C. GEM-CAR
- D. GEM mapping
正解：A、B、C
解説：
GPON traffic policing/shaping is commonly applied at multiple layers:
T-CONT rate control (T-CONT-CAR): controls upstream bandwidth per T-CONT.
GEM-port rate control (GEM-CAR): limits per GEM port.
Service flow rate control (Flow-CAR): enforces per-service policies.
GEM mapping is a forwarding association (service#GEM) and not itself a rate-control mechanism.
References: HCIP-Access V2.5 Study Guide (GPON QoS model: T-CONT, GEM, and service flow policing
/shaping).
質問 # 29
The number of users under the OLT can also determine whether the VLAN is single-layer or dual-layer VLAN. Single-layer VLANs can be used when the number of users is small, and dual-layer VLANs must be used when the need to distinguish services and the number of users is second to ().
- A. CS
- B. 2K
- C. 4K
- D. 1K
正解：C
解説：
A single-layer VLAN is limited by the IEEE 802.1Q VLAN ID space (1-4094), i.e., about 4K VLANs. In large PON deployments, when you must separate multiple services (e.g., HSI, VoIP, IPTV) and the user scale approaches or exceeds the 4K ceiling, a dual-layer VLAN (QinQ) design is required to extend the VLAN namespace and implement hierarchical isolation (access VLAN + service/aggregation VLAN).

正解：B
質問 # 31
Deploying an Ethernet port protection group in the upstream direction of the OLT can improve the reliability and the bandwidth of the uplink.
- A. FALSE
- B. TRUE
正解：A
解説：
An Ethernet port protection group is a 1:1 protection mechanism that improves reliability through active
/standby switching. It does not aggregate bandwidth-the standby port does not forward traffic unless a switchover occurs. If increased bandwidth is required, technologies such as LACP are used instead.
References: HCIP-Access V2.5 - Uplink Protection vs. Link Aggregation; OLT Ethernet Port Protection Group Feature Description.
質問 # 32
(Radio) When the 0LT global or VLAN service template enables the PITP switch, the service port allows the upstream packet to be carried, the Vendor tag switch, and the user to carry the vendor upstream packet In the case of tarf information, the following statement regarding olts to PITP message processing strategies is correct
- A. OLT forwards the USER-side PITP message directly without any processing
- B. OlT is left with the Vendor tag carried in the upstream PITP message, plus the local Vendor tag
- C. OLT adds a local Vendor tap to the upstream PITP packet
- D. OLT drops upstream PITP packets
正解：B
質問 # 33
(Radio) The following options, regarding the description of the H.248 connection model, are correct?
- A. A media gateway that supports only point-to-point connections can allow three or more endpoints to
exist in the --association at the same time - B. When the session between the two users ends, the corresponding association is used
- C. The connection model cannot be modified during a user session
- D. When the user call is successful, the empty connection starts to be created
正解：B
質問 # 34
In the upstream direction of the OLT, link aggregation can be used to improve bandwidth and reliability. Which of the following OLT uplink aggregation modes are supported?
- A. Automatic
- B. Manual
- C. Static
- D. Dynamic
正解：C、D
質問 # 35
When the H.248 protocol is used to deploy the VoIP service, the registration information sent by the MG to the MGC contains the following information:
Services {Method=Restart Reason=[901]}
Which command can trigger the information?
- A. Reset coldstart
- B. Board restart
- C. ONT re-register
- D. Reboot system
正解：B
解説：
The MG reports availability and restarts to the MGC using H.248 ServiceChange with Method=Restart. The Reason code distinguishes the type of restart. In Huawei implementations aligned with H.248 semantics, Reason=[901] corresponds to a warm/warmboard restart scenario rather than a full cold start.
Board restart triggers a warm restart of the voice board/MG, producing ServiceChange { Method=Restart, Reason=901 }.
Reset coldstart performs a cold start, which would use a different reason code (cold start), not 901.
Reboot system generally implies a broader device reboot similar to cold start semantics, not 901.
ONT re-register affects ONU registration and does not cause the MG to announce a ServiceChange restart to the MGC.
References: HCIP-Access V2.5 Study Guide (H.248 ServiceChange usage and restart reporting); Huawei VoIP/MG Board Maintenance Guide (warm vs cold restart indications in ServiceChange).
質問 # 36
(Single-choice) An IPTV user reflects that the TV cannot be watched, open the debug switch on the OLT side,
and the debug printing information is as follows: huawei( config).
This can be judged by the results of the query
- A. The poN port multicast bandwidth is insufficient
- B. The user does not have permission to watch the show
- C. IGMP Sakamoto Fussel
- D. User bandwidth validation failed
正解：D
質問 # 37
(Radio) A power access service deploys GPON Type C dual-attribution protection, and the protection group is bound to the uplink Ethernet-port status on the OLT. When the Ethernet port associated with the protection group on the OLT goes Down, the following description is incorrect.
- A. The state of the ONU-side work port changes to standby
- B. After switchover, the ONU's service is sent to the OLT through the protect port (service traffic follows the protect path)
- C. The OLT detects the ONU uplink state change
- D. The ONU detects the link failure and triggers the protection switchover
正解：D
解説：
In GPON Type C dual-attribution protection, the ONU has dual PON connections to two OLT PON ports (or two OLTs). When the protection group is configured to track the OLT's uplink Ethernet port, a Down state on that uplink is an OLT-side trigger. The OLT initiates the protection action (forces the working/standby role swap via PON protection signaling).
A - Correct behavior: After the OLT triggers protection, the ONU's working PON interface becomes standby, and the protect interface becomes working.
B - Correct behavior: The OLT monitors and updates the ONU uplink status as part of the protection group state machine.
C - Correct behavior: After inversion, services egress the ONU via the protect PON port toward the OLT, i.
e., traffic follows the configured protect path.
D - Incorrect (answer): In this scenario the trigger is the OLT's uplink Ethernet status, not an ONU-detected failure. Therefore the ONU does not detect the fault nor initiate the switchover; the OLT does.
(Reference: HCIP-Access V2.5 - GPON protection mechanisms; Huawei OLT protection group behavior, Type C dual-homing with uplink-tracking.)
質問 # 38
(Radio) When configuring multicast services on MA5600T/MA5680T, the programs of multicast VLANs are statically configured. Which of the following must be configured, otherwise the multicast programs may not be able to be watched?
- A. igmp profile
- B. igmp preview
- C. igmp priority
- D. igmp program
正解：D
解説：
On Huawei OLTs (e.g., MA5600T/MA5680T), deploying IPTV/multicast commonly uses a program list (channel list) to map program numbers to multicast group addresses-this is configured with igmp program.
When programs are statically configured under the multicast VLAN, the program definitions themselves are mandatory; without them, set-top boxes cannot select (zap to) channels by program number/address mapping and the OLT cannot correctly forward the requested multicast streams.
質問 # 39
The complete SIP message interaction process contains multiple requests and responses. Which SIP header field is used to indicate which specific request a given response corresponds to?
- A. Call-ID
- B. CSeq
- C. Message body
- D. First line
正解：B
解説：
Per RFC 3261 (SIP), "The CSeq header field of the response MUST equal the CSeq field of the request." CSeq carries a sequence number and the method, thereby associating a response with the specific request it answers. While Call-ID ties together all messages within the same dialog, it does not identify the specific request/response pairing; CSeq does. Therefore, CSeq is the correct header for correlating a response to the exact request.
質問 # 40
If multicast services are deployed only on private networks, which multicast address segment is preferred?
- A. 239.0.0.0/8
- B. 225.0.0.0/8
- C. 232.0.0.0/8
- D. 224.0.0.0/8
正解：A
解説：
For enterprise/private multicast, Huawei adopts the administratively scoped range 239.0.0.0/8 for internal multicast groups. 232/8 is typically used for SSM in public domains, 224/8 contains link-local and well- known groups, and 225/8 is not defined as the preferred private scope.
