Free Huawei H12-811_V1.0 Practice Exam with Questions & Answers | Set: 5

Network Communication Types:

A: Downloading emails is an example of client-server communication.

B: Accessing a website involves HTTP/HTTPS communication.

C: Chatting via instant messaging involves real-time data exchange using protocols like XMPP or WebSockets.

D: Watching online videos involves streaming protocols like HTTP Live Streaming (HLS).

Conclusion:

All options represent common types of network communication between devices.

Comprehensive Explanation: The country code setting on wireless devices like access points determines the allowable transmission frequencies and maximum transmission power based on the regulatory requirements of the specific region. For example, certain frequency channels or power levels may be restricted in different countries to avoid interference with other services, and the country code configuration ensures that the device operates within those legal limits.

Routing preference (administrative distance) is the first criterion used when multiple paths exist.

If multiple routes have the same preference, the router then compares the cost (metric) to choose the best path.

Lower cost values indicate better paths and are preferred by the router.

If multiple paths have the same cost, the router may perform load balancing (depending on the routing protocol).

Thus, the correct answer is A (TRUE).

The IPv4 header length is variable and is determined by the Header Length (IHL) field in the IPv4 header.

Minimum header size: 20 bytes (5 x 4B) → No options field.

Maximum header size: 60 bytes (15 x 4B) → Includes maximum options.

Option A (Incorrect - 64B): The maximum possible length of an IPv4 header is 60B, so 64B is not possible.

Option B (Correct - 20B): This is the standard IPv4 header size without options.

Option C (Correct - 60B): This is the maximum IPv4 header size with options.

Option D (Correct - 32B): This is a possible IPv4 header size with some options.

Thus, the correct answer is A (64B).

Detailed Explanation:When a command entered on Huawei’s Versatile Routing Platform (VRP) is incomplete, VRP generates an error message indicating that the command is incomplete at a specific position (designated by 'A'). This message helps administrators identify where additional parameters are needed to complete the command syntax. Other error messages indicate issues such as excess parameters or ambiguous commands. (Reference: HCIA-Datacom Lab Guide, VRP Command Syntax)

Detailed Explanation:The priority (preference) of static routes can indeed be manually specified in Huawei devices. By default, static routes have a preference of 60, but this can be changed to create backup routes or prioritize certain routes over others.

Comprehensive and Detailed Explanation:
