H12-811_V1.0 Exam Dumps - Huawei HCIA-Datacom Questions and Answers

Detailed Explanation:

Dynamic routing protocols, such as OSPF and RIP, automatically discover and generate routes, adjusting when network topology changes occur. This helps in reducing the manual configuration required by static routes and ensures that the network adapts efficiently to changes such as link failures or the addition of new routes.

Detailed Explanation:In Huawei VRP, the command-privilege command is used to modify the privilege level of a specific command. In this case, the command adjusts the privilege level of the save command within the user view to level 3, which is higher than the default level. This command does not modify the user's privilege level itself but changes the required privilege level to use the save command in the user view .

With a subnet mask of /25, the IP range for this subnet would be 192.168.1.0 to 192.168.1.127. Here, 192.168.1.127 is the last usable address in the subnet, making it a valid host address rather than a network or broadcast address. This address falls within the range of available host addresses for that subnet​.

Comprehensive Explanation: Router A needs a static route to reach the Loopback interface (10.0.2.2/32) on Router B. The correct next-hop IP address is 10.0.12.2, which is Router B's interface IP address directly connected to Router A​

Bridge Priority Overview:

Bridge Priority is a key parameter in Spanning Tree Protocol (STP) and is used to elect the root bridge.

The default bridge priority for Huawei switches is 32768, which is the default for many vendors.

How STP Uses Bridge Priority:

Lower bridge priority values are preferred during root bridge elections.

Administrators can modify this value for desired root bridge placement.

Understanding Switch Stacking:

Switch stacking allows multiple physical switches to operate as a single logical switch.

Huawei iStack technology supports stacking multiple switches.

Benefits of Stacking:

Simplified Management: Single configuration and management point.

Increased Redundancy: Failover and link aggregation improve reliability.

Scalability: More switches can be added as needed.

Conclusion:

More than two switches can be stacked, making the statement TRUE.

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)

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.
