Huawei H12-891_V1.0 Exam With Confidence Using Practice Dumps

Intra-Area-Prefix-LSA (Type 9) is used in OSPFv3 to carry IPv6 prefix information for a router or network and is flooded within the area.

Link-LSA (Type 8) is only sent on the local link and is not flooded throughout the area.

Inter-Area-Prefix-LSA (Type 3) and Inter-Area-Router-LSA (Type 4) are also flooded within an area but originate from ABRs, typically for cross-area route advertisement.

That said, Intra-Area-Prefix-LSA is specifically flooded within an area, matching the context of the question directly.

Exact Extract - Huawei HCIE-Datacom OSPFv3 Module:

“Intra-Area-Prefix-LSAs are flooded within the area and advertise the IPv6 prefixes associated with router and network LSAs.”

Comprehensive and Detailed In-Depth Explanation:

In the Huawei iMaster NCE-Campus solution, when using a third-party Portal authentication application, the following process occurs:

After the Wi-Fi user connects to the network, any attempt to access a website for the first time triggers HTTP redirection.

The user is redirected to the login page provided by the third-party authentication application.

This mechanism ensures that the user authenticates before accessing external resources.

The redirection behavior is consistent with captive portal functionality, which is standard for user authentication on Wi-Fi networks.

Therefore, the statement is TRUE.

SRv6 Instruction Naming Conventions

SRv6 (Segment Routing over IPv6) uses segment identifiers (SIDs) with specific functions, indicated by instruction keywords:

✅ A. T: Searches a specified routing table to forward packets.

T (Table Lookup) → Performs a lookup in a specified routing table and forwards packets accordingly.

❌ B. M: Searches a Layer 2 forwarding table for unicast forwarding.

Incorrect! SRv6 does not use M for Layer 2 unicast forwarding.

✅ C. V: Searches a VPN instance routing table to forward packets.

V (VPN Routing Table Lookup) → Performs a lookup in a VPN instance (VRF) table for forwarding.

✅ D. X: Forwards packets through one or a group of specified Layer 3 interfaces.

X (Cross-connect forwarding) → Forwards packets via a specified Layer 3 interface or group of interfaces.
