H12-811_V1.0 Exam Dumps - HCIA-Datacom V1.0 Exam

Comprehensive and Detailed Explanation:

The first command:

ip route-static 10.1.1.0 24 12.1.1.1 permanent

Sets a static route to 10.1.1.0/24 via next-hop 12.1.1.1 and marks it permanent (remains in the table even if unreachable).

The second command:

ip route-static 10.1.1.0 24 13.1.1.1

Configures a backup route to 10.1.1.0/24 via next-hop 13.1.1.1.

This route only becomes active if the primary route (12.1.1.1) fails.

Comprehensive and Detailed Explanation:

Huawei devices support the following Telnet authentication methods:

No authentication → Users can log in without a password. ✅

Password authentication → Requires a static password for access. ✅

AAA local authentication → Uses a centralized database for user authentication. ✅

❌ Incorrect Option:

MD5 authentication is NOT used in Telnet. SSH uses MD5 for key exchange, not Telnet.

✅ Reference: HCIA-Datacom Security Guide – Telnet & SSH Authentication

IP Address Uniqueness on VLANIF Interfaces:Each VLANIF interface represents a different logical interface, often tied to distinct subnets. IP addresses for VLANIF interfaces must be unique on the same switch to prevent address conflicts and routing issues​​.

Correct Answer:TRUE. The IP addresses of VLANIF interfaces on the same switch must be different.

OSPFv1 (B): Was an experimental version, not widely used.

OSPFv2 (C): Used for IPv4 networks, does not support IPv6.

OSPFv3 (D): Specifically designed for IPv6 networks and includes additional features like security and address scope handling.

OSPFv4 (A): This version does not exist.

Thus, the correct answer is D (OSPFv3).

Detailed Explanation:In a Layer 2 WLAN, an Access Controller (AC) typically handles authentication and management but does not act as a gateway. Instead, a Layer 3 device, such as a router, serves as the gateway. (Reference: HCIA-WLAN Training Material, WLAN Layer 2 and Layer 3 Concepts)

The tracert (Trace Route) command is a network diagnostic tool used to trace the path that packets take from the source device to the destination.

It works by sending ICMP Echo Requests (or UDP packets) with increasing TTL (Time-To-Live) values and recording responses from each hop along the way.

This helps network administrators identify routing issues, network delays, and connectivity problems in the forwarding path.

The command is commonly used in Huawei VRP to diagnose network latency or packet loss between different nodes.

Thus, the correct answer is A (TRUE).
