Static IP addressing for servers in campus network planning is crucial for maintaining stable network access to server resources. Static IPs ensure that critical devices like servers have fixed addresses, allowing for predictable network access and reducing potential IP conflicts, which enhances network reliability. This practice is endorsed in Huawei's guidelines for effective campus network design and is considered a best practice for managing servers on a network​.

Detailed Explanation:RSTP (Rapid Spanning Tree Protocol) combines the Blocking, Listening, and Disabled states into Discarding, reducing the number of states to Discarding, Learning, and Forwarding. RSTP does not use a separate Listening state, as in standard STP. (Reference: HCIA-Datacom Training Material, RSTP Port States)

STP Forwarding State:In the forwarding state, a port can:

Send and receive BPDUs (Bridge Protocol Data Units).

Learn source MAC addresses from incoming frames.

Forward frames to their destinations​​.

Analysis of Options:

Option A: Correct. Ports in the forwarding state send BPDUs to maintain network topology.

Option B: Incorrect. Ports in the forwarding state do learn source MAC addresses.

Option C: Correct. Ports in the forwarding state receive BPDUs.

Option D: Correct. Ports in the forwarding state forward data frames.

Correct Answer:B. A port in a forwarding state does not learn the source MAC address of a frame is incorrect.

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.

Comprehensive and Detailed Explanation:

In PPP (Point-to-Point Protocol) connections, a static route can be configured using:

Next-hop IP address

Outbound interface

Since PPP links are point-to-point, the router can directly forward packets without needing an explicit next-hop address.

Example configurations:

ip route-static 10.1.1.0 24 Serial0/0/0

ip route-static 10.1.1.0 24 192.168.1.2

✅ Reference: HCIA-Datacom Routing Guide – Static Route Configuration on PPP

In VRP, to enter the configuration view for a specific OSPF area, the syntax [Huawei-ospf-1] area 0.0.0.0 is used. This command specifies Area 0 in the correct format (dotted decimal notation) as required by VRP, which supports OSPF multi-area configuration by designating specific area views​.

Detailed Explanation:DNS (Domain Name System) is responsible for translating human-readable domain names (like www.example.com) into IP addresses, enabling devices to locate services on a network. (Reference: HCIA-Datacom Training Material, DNS Function and Protocol Overview)

In OSPF networks, a DR (Designated Router) is elected for each broadcast domain, such as each Ethernet segment. Given the topology where there are multiple Ethernet segments, a DR will be elected in each segment, resulting in three DRs based on the configuration and network design​.

Comprehensive Explanation: In this configuration, LSW1 and LSW2 have trunk links that allow VLAN 10 to pass between them. When a ping is sent from R1, the frame is tagged with VLAN 10 on LSW2, and this tagged frame is forwarded to LSW1. Since the trunk allows VLAN 10, the tagged data frame is successfully received and processed by LSW1.
