NEW QUESTION # 72
(Radio) In the ACL, if you need to filter packets by source IP, destination IP, and port number, the ACL number template to create is:
- A. 2000-2999
- B. 4000-4999
- C. 5000-5999
- D. 3000-3999
Answer: D
Explanation:
On Huawei VRP, Advanced IPv4 ACLs (which can match source IP, destination IP, and L4 port numbers) use the 3000-3999 numbering range.
2000-2999 = Basic IPv4 ACL (matches source IP only).
3000-3999 = Advanced IPv4 ACL (matches source/destination IP, protocol, ports).
4000-4999 = Layer 2 (MAC) ACL.
5000-5999 = User-defined/other ranges, not the standard advanced IPv4 range.
Therefore, to match IPs and ports, select 3000-3999.

NEW QUESTION # 73
The Class D multicast address range is from 224.0.0.0 to 238.255.255.255.
- A. False
- B. True
Answer: A
Explanation:
IPv4 multicast (historically "Class D") occupies the address block 224.0.0.0 through 239.255.255.255. Any upper bound of 238.255.255.255 is incorrect because it excludes the full 239/8 administratively scoped range.
This is standardized in the IANA IPv4 Multicast Address Space registry and reflected in foundational multicast specifications.
NEW QUESTION # 74

(Radio) A power access service deploys GPON Type C dual attribution protection, and the protection group is
fixed with the upstream Ethernet port status on the OLT, and when the Ethernet port status associated with the
protection group on the OLT becomes down, the following description is incorrect.
- A. After the inversion, the service on the ONU is sent to the OLT through the protect port, that is, the
service packet is transmitted on the protect example planting road - B. The state of the onU side work port changes to standby
- C. The ONU detects link failures and triggers protection reversals
- D. OLT laughs at onu uplink state changes
Answer: C
NEW QUESTION # 78
(Radio) Follow the multicast IP address 227.120.1.32. The correct multicast MAC address corresponding to it is:
- A. 01-00-5e-14-01-32
- B. 01-00-5e-78-01-20
- C. 01-00-5e-14-01-20
- D. 01-00-5e-78-01-32
Answer: B
Explanation:
For IPv4 multicast, the destination MAC is derived by mapping the lower 23 bits of the multicast IP address into the OUI 01-00-5E. The 4th MAC byte is the lower 7 bits of the IP's second octet (so it ranges 00-7F), and the 5th and 6th MAC bytes are the third and fourth IP octets directly:
Multicast OUI: 01-00-5E
IP: 227.120.1.32
2nd octet = 120 (0x78). Its lower 7 bits are still 0x78 (since the MSB is 0).
3rd octet = 1 (0x01)
4th octet = 32 (0x20)
Therefore the MAC is 01-00-5E-78-01-20 # option C.
(This mapping aligns with standard IPv4 multicast-to-Ethernet rules described in Huawei's multicast overview sections in HCIP-Access materials and Huawei OLT product guides.)
NEW QUESTION # 79
The (radio) prerequisites for eSight to automatically discover OLT and MXU devices by IP address are not included
- A. The SNMP parameters on the eSight side have been configured and are aligned with the device side SNMP parameters.
- B. eSight and the device can be routed to communicate (ping each other).
- C. eSight and the device need to be on the same network segment, otherwise the device cannot be discovered using the ARP broadcast protocol.
- D. You already have the operation permission of "Resource Access".
Answer: C
Explanation:
In IP address discovery mode, eSight does not require L2 same-subnet adjacency; it only requires IP reachability/routing, proper SNMP credentials/alignment, and the operator's Resource Access permission to poll and add devices. The "same network segment" prerequisite applies to ARP broadcast discovery mode, not to IP address discovery.

NEW QUESTION # 80
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 discards the user-side DHCP packet.
- B. The access device directly forwards the user-side DHCP packet without any processing.
- C. The access device strips the Option 82 information from the user-side DHCP packet and forwards the packet.
- D. The access device strips the Option 82 from the user-side DHCP packet and adds the local user information.
Answer: D
Explanation:
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.

NEW QUESTION # 84
(Radio) The 10G GPON system uses XGEM frames to encapsulate data, and the Port-ID is defined in the XGEM header as () bits.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
XG-PON (10G GPON) adopts XGEM framing. Compared with GPON's 12-bit GEM Port-ID, XGEM expands the Port-ID field to 16 bits, increasing the number of logical data flows that can be identified per ONU/OLT and improving service granularity. Hence the correct length is 16 bits.

NEW QUESTION # 88
(Radio) Regarding multicast, the following description is incorrect:
- A. The user-issued IGMP Report is captured in the line board logic and sent to the line board CPU.
- B. Add IGMP user under BTV; by default, multicast users can watch 8 programs.
- C. When the IGMP match mode is disabled, you need to configure the multicast program group.
- D. Device-based global configurations of Layer 2 multicast refer to common parameters of protocols (IGMP Proxy, IGMP Snooping) for all.
Answer: D
Explanation:
A (True): Huawei multicast configuration defaults commonly allow a user to watch up to 8 programs simultaneously unless overridden (e.g., max-program-num default 8 in multicast/VLAN views and controllable multicast profile).
B (True): On Huawei access devices, IGMP Reports from users are processed by the line card (board) logic
/CPU as part of IGMP Snooping/controllable multicast handling to build forwarding entries. (See Huawei IGMP Snooping/Proxy architecture descriptions.) C (Incorrect): IGMP Snooping is a Layer 2 function, but IGMP Proxy is a Layer 3 function (runs on a gateway to originate Queries and proxy membership upstream). Grouping them together as "Layer 2 global parameters" is incorrect. Huawei documentation distinguishes IGMP Snooping (L2) from IGMP Proxy (L3).
D (True in practice): When automatic matching is not used, multicast program groups/channels must be configured so that user joins map to provisioned program entries (consistent with Huawei controllable multicast/BTV configuration workflows).
NEW QUESTION # 89
The protection scope of GPON Type B dual-homing protection covers ( ).
- A. Active and standby OLTs
- B. Active and standby backbone optical fibers

NEW QUESTION # 90
Which of the following statements about terminal selection principles are correct?
- A. Special requirements must be considered.
- B. Project requirements do not need to be considered.
- C. Terminal types should be selected based on the network construction mode.
- D. Cost needs to be considered.
Answer: A,C,D
Explanation:
Terminal (ONT/ONU/CPE) selection adheres to engineering principles: align model and interfaces with the deployment mode and scenario, evaluate TCO/cost, and satisfy special requirements (such as PoE, Wi-Fi specs, voice/FXS, industrial temperature). Ignoring project requirements is contrary to standard design workflows; therefore D is not correct.
