NO.11 For the packets from the client side, the flow matching is performed preferentially according to the VLAN tag carried in the packets. If the matching fails and the TLS service flow is deployed on the device, the packets are matched to the TLS service flow.

TRUE

FALSE

NO.12 The priority of the packets at the egress port can be mapped or set directly. Which of the following statements about priority processing is correct?

The priority policy must be tag-in-package regardless of the priority setting mode.

The priority mapping can be set separately for the inner and outer priorities.

The priority mapping needs to match the corresponding mapping profile. The mapping in a profile is fixed.

Priorities of outbound and inbound packets are strictly mapped. An outer VLAN ID cannot be mapped to the priority of an inner VLAN ID.

NO.13 Which of the following statements about the E2E ODN pre-connection solution are correct?

Easy deployment, 100% splicing-free, no need for professional skills and tools, and improved efficiency

Splitters are installed in pre-connected boxes and occupy small space.

The pre-connection solution uses distributed optical splitting to reduce the number of drop cables, thereby reducing the number of pipes and cables.

Easy to maintain, no need for fiber splicing, and low maintenance skill requirements

NO.14 Which of the following statements about multicast is incorrect?

General parameters for multicast protocols (IGMP proxy and IGMP snooping) are configured globally at Layer 2 and apply to all multicast VLANs.

The report sent by a user is captured by the board logic and sent to the CPU of the board.

You can add IGMP users to a BTV. By default, a multicast user can watch 8 programs.

In the case of IGMP match mode disable, you need to configure a multicast channel.

NO.15 After the anti-IP attack function is enabled on an OLT, the OLT cannot be remotely managed through Telnet.

TRUE

FALSE

The OLT’s anti-IP-attack (control-plane protection) function identifies and rate-limits abnormal or attack traffic to protect the CPU. It does not block legitimate management protocols such as Telnet/SSH by design.
Remote management remains available when sourced from permitted hosts and within configured thresholds; administrators can also use trusted-host/ACL policies if needed.
References: HCIP-Access V2.5 – Security Hardening on OLT (CPU defend/anti-attack), OLT Maintenance and Management Guide – Remote Management and Trusted-Host Control.

NO.16 In the evolution of EPON to 10 G EPON, a smooth transition is achieved at the local level by adding WDM
WDM modules, and ODNs coexist

True

False

NO.17 In Huawei U2000, when adding network elements, you can only add them one-by-one while accessing each network element.

Wrong

Right

This statement is wrong. In U2000, network elements (NEs) can be added by multiple methods, including batch addition/import and automatic discovery, not just one-by-one during a live access session. U2000 supports template-based onboarding and batch operations to improve efficiency for large-scale deployments.
References: HCIP-Access V2.5-Network Management chapter (U2000 NE addition methods, discovery, and batch import); Huawei U2000 Administrator Guide (NE management and batch operations).

NO.18 (Multiple choice) Which of the following measures can be adopted by GPON in terms of traffic control?

GEM-CAR

GEM mapping

Flow-CAR

T-CONT-CAR

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).

NO.19 Layer 2 enables IGMP-snooping , and when the switch port receives an IGMP join packet, it listens for the
packet and adds the corresponding port to the multicast group

wrong

Right

NO.20 When the Type C dual home protection linkage uplink detection, if the OLT or OLT uplink fails, the Type C
dual home protection can be reversed to another OLT

True

False

NO.21 Which one of the following protection schemes can provide OLT-level protection?

Type B dual-homing

Ethernet port protection group

LACP

Type B single-homing

NO.22 (Radio) Regarding the H.248 connection model, which description is correct?

The connection model cannot be modified during a user session

When the session between two users ends, the corresponding association is used

A media gateway that supports only point-to-point connections can allow three or more endpoints in the same association at the same time

When the user call is successful, the empty connection (context) starts to be created

In H.248, the MGC controls the MG by creating a Context (also called an empty connection) and then adding terminations to build point-to-point, multipoint, or conference topologies. During call setup the MGC typically creates an empty context first, then binds terminations as media is negotiated.
A is incorrect: contexts and terminations can be modified during the session.
B is incorrect as written (the association/context is released, not “used”).
C is incorrect: an MG limited to point-to-point cannot host three or more endpoints in one context.
References: HCIP-Access V2.5 Study Guide – H.248 architecture: associations, contexts (empty connection), terminations, and connection modification procedures.

NO.23 (Multiple choice) When the OLT main control board CPU is detected to be continuously elevated, the following possible causes are?

The user logged in illegally

Network loops

Cyber attacks

Rogue ONU

NO.24 According to the NGN architecture, drag the following devices to the corresponding layers. (Score only when all the answers are correct.)

NO.25 Sequence of upstream QoS processing on the OLT:

Traffic classification > Marking > ACL policy > Congestion avoidance > Congestion management

Marking > Traffic classification > Congestion avoidance > Traffic policing > Congestion management

Traffic classification > Marking > Congestion avoidance > Traffic policing > Congestion management

Traffic classification > Marking > Traffic policing > Congestion avoidance > Congestion management

On Huawei OLTs, the standard QoS pipeline for upstream packets is: first perform traffic classification (identify flows), then marking (set CoS/DSCP as required), next apply traffic policing (rate-limit and color traffic), followed by congestion avoidance (AQM such as RED/WRED), and finally congestion management (queue scheduling/priority queuing). This ordered sequence ensures correct identification and marking before any rate enforcement, and that packets encounter AQM prior to scheduler-based dequeue.
Reference: HCIP-Access V2.5 – QoS Framework and Processing Sequence on OLT (classification # marking
# policing # AQM # scheduling).

NO.26 If a rogue ONU exists on a PON port of the OLT and has gone online, another ONT or all ONTs connected to the same PON port may go offline or go online and offline frequently.

TRUE

FALSE

A rogue ONU that transmits out of schedule or at abnormal optical levels can disrupt upstream time-slotting on the PON, causing collision and interference. This can force other ONUs on the same PON to deregister or flap frequently. Huawei OLTs provide rogue ONU detection/isolation to protect the PON.
References: HCIP-Access V2.5 Study Guide (PON Faults-Rogue ONU Impact and Handling); Huawei OLT Maintenance Guide (Rogue ONU detection and isolation).

NO.27 The auto-discovery methods provided by sight are by network segment mode, ARP mode and routing mode.
At the same time, you can create a network segment or IP address of a device that does not need to be
connected as an exclusion list. Automatically skips the network segment or IP address configured in the
exclusion list during self-discovery of devices.

True

False

NO.28 Under IGMP snooping, there are two users on demand under the OLT- the same program, and the olt sends two join messages to the multicast router

wrong

Right

NO.29 The total downstream bandwidth of the 10G EPON PONI port is the sum of the EPON downstream bandwidth and the 10G EPON downstream bandwidth.

True

False

NO.30 (Radio) The downstream effective bandwidth of a GPON PON port is:

2 Gbit/s

1.25 Gbit/s

2.5 Gbit/s

2.2 Gbit/s

GPON (per ITU-T G.984.x and Huawei OLT specifications) provides a downstream line rate of ~2.488 Gbit
/s, commonly denoted as 2.5 Gbit/s, and an upstream rate of ~1.244 Gbit/s (1.25 Gbit/s). Therefore, the downstream effective bandwidth option that matches GPON is 2.5 Gbit/s.
References: HCIP-Access V2.5-PON technology overview (GPON rates); Huawei OLT Product Description (GPON port downstream/upstream rates).

NO.31 The ONU optical module has requirements on the type of the fiber connector. Before the design and selection, read the ONU specifications carefully and select a proper fiber connector.

TRUE

FALSE

NO.32 Which of the following statements about congestion avoidance is incorrect?

To prevent high-priority packets from being discarded, the early drop threshold of high-priority packets is set to a smaller value.

Congestion avoidance is a traffic control mechanism that monitors the usage of network resources (such as queues or memory buffers) and discards packets when the system is congested to adjust the traffic and mitigate network overload.

The RED technology can reduce the jitter during packet transmission.

Tail drop causes global TCP synchronization and reduces bandwidth usage.

In AQM, high-priority queues are given more tolerant (larger) thresholds so they are less likely to be dropped early. Setting a smaller early-drop threshold for high priority would increase their loss probability, which contradicts QoS objectives-thus A is incorrect. Descriptions in B, C, and D align with Huawei’s treatment of congestion avoidance: RED/WRED proactively drops to stabilize queues and can reduce delay variation; tail drop at full buffer can lead to global TCP synchronization.
Reference: HCIP-Access V2.5 – Congestion Avoidance (RED/WRED behavior, thresholds, and TCP effects of tail drop).
