Pass the Huawei HCIA-Datacom H12-811_V1.0 Questions and answers with CertsForce

In RSTP (Rapid Spanning Tree Protocol), the Backup port serves as a backup for the Designated port on the same bridge segment, not the root port. If the root port fails, the alternate port, not the backup port, takes over to maintain connectivity to the root bridge. The backup port does not have the capability to replace the root port​.

In Huawei’s VRP, the default preference value for OSPF routes is generally 10, but this value can be adjusted based on configuration requirements. Therefore, it is not necessarily always set to 10, as network administrators may alter the preference to prioritize different routes. This flexibility allows customization based on the network ' s specific routing needs​.

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.

CAPWAP (Control and Provisioning of Wireless Access Points) is a protocol that enables centralized control of Fit APs by an AC (Access Controller).

Option A (Incorrect): CAPWAP tunnels only control traffic, while data traffic can be sent via direct forwarding or tunneled forwarding.

Option B (Incorrect): A Fit AP can discover an AC via multiple methods, including broadcast, static configuration, or DHCP Option 43.

Option C (Correct): APs encapsulate user data into CAPWAP packets and send them to the AC for further processing.

Option D (Incorrect): CAPWAP is based on UDP, not TCP, for better efficiency and lower latency.

Thus, the correct answer is C.

Detailed Explanation:The protocol number for TCP in the IPv4 header is 6. Since Telnet uses TCP as its transport layer protocol, the protocol field in the IPv4 header will contain the value 6​​.

Comprehensive and Detailed Explanation:

A static route requires the following essential parameters:

Destination Network → The network to reach (e.g., 10.1.1.0/24). ✅

Next-hop IP Address → The next router to forward traffic (e.g., 192.168.1.1). ✅

Outbound Interface → Instead of a next-hop, an interface (e.g., GigabitEthernet0/0/1) can be used. ✅

❌ Incorrect Option:

MAC address is not needed because routers forward packets based on IP, not MAC addresses.

Comprehensive Explanation: WEP (Wired Equivalent Privacy) is the only security policy in this list that supports open link authentication, which means no actual user credentials are required to associate with the network. WEP uses a shared key for encryption but offers minimal protection and is considered insecure. Other security methods like WPA, WPA2-PSK, and WPA2-802.1X use more secure forms of authentication, requiring credentials such as a password or centralized authentication server.
