NEW QUESTION # 60
The total downstream bandwidth of the 10G EPON PONI port is the sum of the EPON downstream bandwidth and the 10G EPON downstream bandwidth.
- A. False
- B. True
Answer: A
Explanation:
According to Huawei HCIP-Access V2.5 learning materials and official Huawei Access Network product documentation, a 10G EPON PONI port supports both EPON (1.25 Gbit/s) and 10G EPON (10 Gbit/s) transmission modes.
These two modes are not combined - they operate on different wavelengths and serve different types of Optical Network Units (ONUs):
EPON uses a 1490 nm wavelength for downstream transmission with a rate of 1.25 Gbit/s.
10G EPON uses a 1577 nm wavelength for downstream transmission with a rate of 10 Gbit/s.
When an OLT (Optical Line Terminal) port supports dual-mode operation, it automatically adapts to the connected ONU type - but it does not aggregate the bandwidth of both technologies. Each ONU communicates using only one rate (either EPON or 10G EPON).
Therefore, the total downstream bandwidth is not the sum of both rates. It depends solely on the ONU's operational mode.Hence, the statement is False.

NEW QUESTION # 63
The (radio) device periodically sends and receives LMCP packets to avoid information loss, and if packets are not received during ( ) LACp packet interaction cycles, the system considers the port to be down
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
NEW QUESTION # 64
(Radio) The device periodically sends and receives LACP packets to avoid information loss. If no LACPDU is received within ( ) LACP interaction cycles, the system considers the member port Down.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
In IEEE 802.1AX/802.3ad LACP operation, timeout detection relies on a multiplier of three consecutive LACP intervals. In short-timeout mode, the default period is ~1 s; if 3 intervals pass without receiving LACPDUs, the peer is considered expired and the member is removed (treated as Down for aggregation).
Huawei implements this standard behavior for port-member validity in an Eth-Trunk.

NEW QUESTION # 66
(Single choice) The following statement about defense MAC Spoofing is wrong
- A. After enabling the Anti-MAC Spoofing function, for IPoE users using fixed IP, the user needs to be statically configured
- B. After the anti-MAC Spoofing function is enabled, the system automatically implements the dynamic binding of the AC address to the service flow
- C. Turning off the Anti-MAC Spoofing function can only take out the fixed table items, which does not affect the user's service application, but the service forwarding surface will be interrupted.
- D. MAC Anti- Mac Spoofing' features are mutually exclusive with WMAC, SC, PPPOE SMAC features at the VLA level
Answer: C
NEW QUESTION # 67
(Single choice) In GPON systems, in order to prevent network monitoring, the most common method is.
- A. Information encryption
- B. Use leased line transmission
- C. Physical transport (not networked)
- D. Cableless network transmission
Answer: A
Explanation:
GPON specifies data encryption (commonly AES-128) on downstream traffic so that one ONU cannot eavesdrop another's data on the shared PON. This cryptographic protection is the standard, practical method to prevent monitoring on GPON access networks; the other options are operational workarounds, not normal GPON security mechanisms.
NEW QUESTION # 68
Max-Forwards fields can be used in S1P messages to solve loop problems and avoid endless packet forwarding.
- A. wrong
- B. Right
Answer: B
NEW QUESTION # 69
In the NGN system, the ( ) adopts the packet technology to provide a unified integrated transmission platform with high reliability, QoS guarantee, and large capacity.
- A. Edge access layer
- B. Service management layer
- C. Network control layer
- D. Core switching layer
Answer: D
Explanation:
In NGN architectures, services (voice, video, data) converge over a packet-based backbone. The core switching layer provides the unified transport using IP/MPLS and related QoS mechanisms, delivering high reliability and large-capacity switching for all upper-layer services. The control and management layers orchestrate services, while the edge/access layer aggregates users-but the packet-based integrated transmission platform itself is the role of the core.

NEW QUESTION # 70
The DBA scheduling of the GPON system is only for the upstream traffic, and the downstream traffic cannot be scheduled.
- A. True
- B. False
Answer: A
NEW QUESTION # 71
After anti-DoS attack is configured, the system periodically checks all user ports on the board. If the system detects attacks for multiple consecutive times, the system adds the corresponding port to the blacklist and waits for a random period before a new round of detection to determine whether to remove the port from the blacklist.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Huawei anti-DoS on access boards performs periodic detection. Ports with consecutive detections of abnormal traffic are placed into a blacklist/quarantine state. The system then applies a random back-off interval before re-detecting; if no further anomalies are found, the port can be automatically removed from the blacklist.
References: HCIP-Access V2.5 Study Guide - Security hardening on access devices (DoS protection, blacklist strategy, periodic detection).
NEW QUESTION # 72
Layer 2 enables IGMP Snooping, and when the switch port receives an IGMP Join (Membership Report), it listens to the packet and adds the corresponding port to the multicast group.
- A. wrong
- B. Right
Answer: B
Explanation:
IGMP Snooping is a Layer-2 function that listens to IGMP control packets between hosts and the multicast querier. Upon receiving a host's Membership Report (Join) for group G, the switch learns that the ingress port is a member port for G and adds that port to the group's forwarding entry, so multicast traffic for G is forwarded only to those learned member ports (saving bandwidth and avoiding flooding). Huawei's official documentation describes IGMP Snooping exactly in this way.
NEW QUESTION # 73
The establishment, maintenance and dismantling of the word path between the SIP user and the server are done through the interaction of the --series of messages, so that every information contained in the SIP text has a --nature, There is no phenomenon in which a single information value appears multiple times.
- A. Right
- B. wrong
Answer: B
NEW QUESTION # 74
The scope of protection of the (multiple choice) GPON Type B dual attribution protection includes
- A. Primary and standby feeder fibers
- B. Primary and standby branch fibers
- C. Primary and standby OLTs
- D. OLT's primary and standby PON ports
Answer: A,D
Explanation:
In GPON protection schemes, Type B (dual-homing to the same OLT) provides redundancy by using two PON ports on the same OLT (working/standby) and a redundant feeder path via a 2×N splitter or equivalent ODN design. Thus, the protection covers the OLT PON interfaces and the feeder fiber segment. It does not provide protection for the branch (distribution) fibers from the splitter to the ONUs, and it does not involve dual OLTs-that is the scope of Type C.

is connected to the detected line, which of the following parameters can be set.
- A. Set the mode
- B. Set the measurement range
- C. Set the wavelength
- D. Sets the pulse width
Answer: A,B,C,D
NEW QUESTION # 77
OLT can support direct replication of a user packet's priority as the forwarding priority, and also supports direct local configuration.
- A. wrong
- B. Right
Answer: B
Explanation:
Huawei OLTs support trust/remark mechanisms that can inherit (copy) user packet priorities (for example, trusting incoming 802.1p or DSCP to drive forwarding queues) and also support locally configured priorities (policy-based remarking/mapping on the OLT) to enforce service differentiation. Thus, both priority inheritance and local priority configuration are supported, making the statement Right.
