NEW QUESTION # 46
The following figure shows some configurations of R1. Based on these configurations, which of the following statements about IS-IS on R1 are correct?
isis 1
is-level level-2
cost-style wide
network-entity 49.0022.ee8c.a0c2.baf1.00
isis 2 vpn-instance tt
is-level level-2
cost-style wide
network-entity 47.00ce.390d.efdc.b3e1.00
isis 3 vpn-instance rr
is-level level-2
cost-style wide
network-entity 47.cc0a.3efb.bbdd.aae1.00
Answer: A,D
Explanation:
Let's break this down step-by-step based on Huawei IS-IS VPN and multi-process behavior.
# Configuration Summary:
Process 1: IS-IS for the global routing table
Process 2: IS-IS for VPN instance tt
Process 3: IS-IS for VPN instance rr
# Option C: Correct
Process 1 contains only global routing information.
The configuration of isis 1 does not include any vpn-instance keyword, meaning it is bound to the global routing table.
It does not interact with VPN routing tables unless explicitly configured with import/export mechanisms or route leaking (which is not shown here).
Huawei Datacom Reference:
"When an IS-IS process is not associated with a VPN instance, it belongs to the global routing table and only maintains global routes." (Source: HCIE-Datacom Study Guide v3.0 - Chapter: IS-IS for IPv4 and IPv6, Section: Multi-Instance Routing)
# Option D: Correct
Routing information of process 2 is isolated from that of process 3.
isis 2 is bound to VPN instance tt
isis 3 is bound to VPN instance rr
Each IS-IS process in Huawei VRF context maintains independent LSDBs and routing tables, and by default, they do not share routing information unless route leaking or redistribution is configured (which is not shown in the config).
Huawei Datacom Reference:
"IS-IS processes bound to different VPN instances operate independently and do not share routing information." (Source: HCIE-Datacom Study Guide v3.0 - Chapter: MPLS L3VPN with IS-IS)
NEW QUESTION # 47
Flavors are additional behaviors defined to enhance the End series instructions in SRv6. Which of the following End instructions can the PSP flavor be attached to?
Answer: B,C,D
Explanation:
Comprehensive and Detailed Explanation:
# SRv6 (Segment Routing over IPv6) Flavors provide additional processing behaviors for SRv6 End instructions.
# PSP (Penultimate Segment Popping) Flavor:
* PSP enables the penultimate node to remove the SRH (Segment Routing Header) before forwarding the packet to the last segment.
* This reduces the processing overhead on the final segment node.
# Correct End Instructions for PSP:# (A) End.X # Cross-connect behavior between segments.# (C) End.T
# Transport encapsulation in SRv6.# (D) End # Basic SRv6 endpoint behavior.
# (B) End.BM is incorrect # This is used for Binding Segment (BSID) behavior and does not support PSP.
# Reference: Huawei HCIE Datacom - SRv6 Flavors and End Instructions
NEW QUESTION # 48
On the campus network shown, IPv6 is deployed for service tests. Four routers are deployed on the network, and these routers use OSPFv3 for network connectivity. Which of the following statements about LSAs generated by the OSPFv3 network is incorrect?
Answer: D
Explanation:
Let's dissect each option based on OSPFv3 LSA behavior from Huawei HCIE Datacom documentation.
✅ Option A: Correct
OSPFv3 uses Router LSAs (Type 1) to describe the local interfaces, links, and neighbors.
R1, as part of Area 0, will generate Router-LSAs and receive Router-LSAs from neighbors in the same area (R2 and R3 via switch S1).
Huawei Datacom Reference:
"Each OSPFv3 router originates a Type 1 Router LSA for each area it belongs to." (Source: HCIE-Datacom Study Guide v3.0 - OSPFv3 Fundamentals)
❌ Option B: Incorrect (Correct Answer)
Link-LSAs (Type 8) are not sent between routers. They are only generated for each link on which the router has at least one neighbor. These LSAs are only flooded on the local link.
R1 cannot receive two Link-LSAs from R2 about both links. It can only receive the Link-LSA that R2 generates for the shared link with R1. The other link (e.g., to R4 in Area 1) is irrelevant to R1.
Huawei Datacom Reference:
"A Link LSA is generated by a router for each attached link and is sent only to the routers on the same link." (Source: HCIE-Datacom Study Guide v3.0 - OSPFv3 LSA Types)
✅ Option C: Correct
On broadcast links, DRs generate Type 2 Network LSAs.
If R3 is the DR on the shared segment (with R1), R1 will have the Network-LSA from R3 in its LSDB.
Huawei Datacom Reference:
"The DR on a broadcast network generates a Type 2 Network LSA to describe all routers on that link." (Source: HCIE-Datacom Study Guide v3.0 - OSPFv3 LSDB Construction)
✅ Option D: Correct
R2 connects Area 0 and Area 1, hence it's an ABR.
ABRs generate Type 3 Inter-Area-Prefix LSAs to advertise IPv6 prefixes from one area to another.
R2 advertises Area 1 prefixes to Area 0 routers (R1 and R3).
Huawei Datacom Reference:
"Inter-Area-Prefix LSAs (Type 3) are generated by ABRs to advertise IPv6 prefixes from one area into another." (Source: HCIE-Datacom Study Guide v3.0 - ABR Functionality in OSPFv3)
NEW QUESTION # 49
If an engineer wants to remotely log in to a Huawei device, the engineer uses the Paramiko library to compile the following code when compiling the SSH Python script:
cli = ssh.invoke_shell()
cli.send("screen-length 0 temporary\n")
What is the function of screen-length 0 temporary?
Answer: C
Explanation:
Understanding screen-length Command in Huawei Devices
🔹 What Does screen-length Do?
Controls how much output is displayed at a time on the Huawei CLI.
By default, command output is paginated (split-screen display).
screen-length 0 temporary disables the split-screen display, allowing continuous output without pauses.
Analysis of Each Option:
❌ A. Performing automatic word wrap → Incorrect
This command does not wrap long text lines, it controls screen pagination.
❌ B. Performing split-screen display → Incorrect
This command disables split-screen display, not enables it.
✅ C. Canceling split-screen display → Correct
This allows continuous command output without "Press Enter to continue" interruptions.
❌ D. Canceling automatic word wrap → Incorrect
Word wrap behavior is not controlled by screen-length.
Real-World Application:
Automated Network Monitoring: Used in Python scripts for uninterrupted CLI output collection.
Log Analysis: Helps in extracting large command outputs for troubleshooting.
✅ Reference: Huawei HCIE-Datacom Guide - CLI Configuration and Automation with Paramiko
