Huawei Updated H12-811_V1.0 Exam Questions and Answers by aubree

Routers can learn routes from various sources:

Static routes: Manually configured routes.

Direct routes: Routes to networks directly connected to the router.

Summary routes: Aggregated routes summarizing multiple networks, often used in routing protocols.

Dynamic routes: Routes learned via routing protocols like OSPF, RIP, or BGP. These sources contribute to the router ' s routing table, enabling it to forward packets to known destinations​.

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: In RSTP (Rapid Spanning Tree Protocol), G0/0/3 of SWB is an Alternate Port because it provides a redundant path to the root bridge, while G0/0/3 of SWA is a Designated Port, forwarding traffic away from the root bridge. Similarly, G0/0/2 of SWA is also a Designated Port because it forwards traffic to other segments of the network. Alternate Ports are used to provide backup paths, while Designated Ports are the forwarding ports on a given segment.
