Huawei H12-811_V1.0 Exam With Confidence Using Practice Dumps

B (Correct): GE0/0/1 is untagged for VLAN 10, meaning it does not add VLAN tags to VLAN 10 frames.

C (Correct): GE0/0/1 is also untagged for VLAN 20, so it does not add VLAN tags to VLAN 20 frames.

D (Correct): The output shows four VLANs (10, 20, 30, 40), which were manually created.

A (Incorrect): GE0/0/2 is not explicitly mentioned, so VLAN tagging behavior cannot be confirmed.

Thus, the correct answers are B, C, and D.

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).

Router Initialization:

When a router boots up, it attempts to load its configuration file from the default save directory to initialize.

If the configuration file is missing, the router defaults to preconfigured parameters to ensure basic functionality.

Default Parameters:

These parameters include IP routing, interface defaults, and system-level settings. They allow network administrators to connect and manually configure the router.

Why Other Options Are Incorrect:

B: The "initial configuration file" refers to the manually created file, which may not exist.

C: The "current configuration file" is used during runtime but does not persist through reboots if unsaved.

D: A "new configuration file" must be manually created and does not exist by default.
