Free Practice Questions for Huawei H12-811_V1.0 Exam

Detailed Explanation:The command forward-mode direct-forward is used to configure the AC to enable direct forwarding, meaning that the AP will forward user data packets directly to the network without tunneling them through the AC, improving efficiency by reducing the load on the AC​.

Detailed Explanation:Static MAC address entries are manually configured and stored in the switch's configuration file, making them persistent across reboots. These entries remain in the MAC address table after a restart, unlike dynamic entries, which are lost. (Reference: HCIA-Datacom Training Material, MAC Address Table Types)

In IPv6, addresses with the FE80::/10 prefix are Link-Local Addresses.

Option A (Incorrect - Global unicast address): These have prefixes such as 2000::/3.

Option B (Incorrect - Multicast address): Multicast addresses start with FF00::/8.

Option C (Correct - Link-local address): FE80::/10 is reserved for Link-Local addresses, used for communication within a local link.

Option D (Incorrect - Anycast address): Anycast addresses are assigned to multiple interfaces but are not identified by a specific prefix.

Thus, the correct answer is C.

Comprehensive and Detailed Explanation:

Huawei controllers support open APIs for network programmability:✅ RESTful → Web-based API using HTTP methods.✅ OpenFlow → SDN protocol for control/data plane separation.✅ NETCONF → XML-based network configuration protocol.

❌ Incorrect Option:

AAA (Authentication, Authorization, and Accounting) is a security mechanism, NOT an open API.

✅ Reference: HCIA-Datacom SDN Guide – Open API Support

The Full state in OSPF means that all routers have completed LSDB synchronization and formed an adjacency.

If LSDB synchronization is incomplete, the router remains in Loading or Exchange state.

Only after the Database Description (DD) packets, Link-State Requests (LSR), and Link-State Updates (LSU) are exchanged, the router enters the Full state.

Thus, the correct answer is A (TRUE).

The command defines a static route to the network 10.0.12.0 with a 255.255.255.0 subnet mask, using 192.168.1.1 as the next-hop address. Static routes are manually set routes with fixed paths, and by default, they have higher priority than dynamic routes, but the specific preference value depends on configuration. This setup enables targeted routing for traffic towards the specified destination​.

Comprehensive Explanation: Static NAT (Network Address Translation) can implement both one-to-one and many-to-one mappings. In a one-to-one mapping, each private IP address is mapped to a unique public IP address. However, in some cases, static NAT can be configured to map multiple private addresses to a single public address, particularly for services that do not require incoming connections. This flexibility allows for more efficient use of limited public IP address space.
