Pass the Huawei HCIP-Access H35-210_V2.5 Questions and answers with ValidTests

Comprehensive and Detailed Step by Step Explanation:

A (Incorrect): XGS-PON encrypts the payload, not the entire packet.

ONT Line Profile Overview :

An ONT line profile defines the mapping and configuration of services for an ONU (Optical Network Unit) on the OLT.

Key Parameters :

Mapping between GEM ports and data packets : Specifies how data packets are mapped to GEM (GPON Encapsulation Method) ports for transmission.

GEM ports : Logical ports used to encapsulate and transmit data over the GPON network.

T-CONT (Transmission Containers) : Allocates upstream bandwidth for different service flows.

Number of Ethernet ports on the ONT : This is a hardware attribute of the ONT and is not defined in the line profile.

Why A, B, C?

These parameters are directly related to the configuration of services and are included in the ONT line profile.

The number of Ethernet ports is unrelated to the line profile and is determined by the ONT hardware.

Thus, the correct answers are A, B, C .

VLAN Tag Translation :

VLAN tag translation is used to modify VLAN tags in packets as they pass through the OLT.

The tag-transform parameter determines how VLAN tags are handled during service flow creation.

Behavior of tag-transform = default :

When tag-transform is set to default, the OLT applies predefined rules for VLAN tag conversion based on the SVLAN (Service VLAN) attributes.

These rules vary depending on the SVLAN type (e.g., Common, QinQ, Stacking), resulting in different behaviors.

Why TRUE?

The statement accurately reflects the behavior of the tag-transform parameter when set to default. Different SVLAN attributes lead to different tag conversion rules.

Thus, the correct answer is A .

OLT Configuration Guide by Huawei.

A: GEM ports must map to T-CONTs for upstream QoS.

C: DBA dynamically allocates upstream bandwidth to T-CONTs.

B (Incorrect): Alloc-IDs must be unique per ONU.

ONU States Overview :

The display ont info command provides detailed information about the status of an ONU (Optical Network Unit), including its operational state.

Key States :

Online : Indicates that the ONU is registered, authenticated, and actively communicating with the OLT. This is the desired state for normal operation.

Active : Refers to the ONU being powered on but not necessarily fully registered or authenticated.

Match : Indicates that the ONU configuration matches the OLT's expected configuration, but this does not guarantee online status.

Offline : Indicates that the ONU is not registered or communicating with the OLT.

Why A?

The Online state explicitly confirms that the ONU is registered, authenticated, and functioning properly within the network.

Thus, the correct answer is A .

Testing Board Reset :

Testing the reset functionality of an OLT board ensures that the board can recover from failures or configuration changes.

Methods for Testing Reset :

Hot Swap : Physically removing and reinserting the board tests its ability to initialize and function after a reset.

RESET Button : Pressing the physical RESET button on the board forces a hardware reset, verifying recovery capabilities.

Reset Command : Using CLI commands (e.g., reset board) resets the board remotely, allowing verification of software-based recovery.

Why D?

All three methods are valid ways to test the reset functionality of an OLT board. Each method addresses different scenarios and ensures comprehensive testing.

Thus, the correct answer is D .
