Sure, I'd be happy to explain the two pieces of information that can be learned by viewing the routing table, as well as why the other answer options are incorrect.
First, it's important to understand what a routing table is. In networking, a routing table is a database that contains information about the paths that data can take as it travels from one network to another. Each entry in the routing table is called a route, and it typically includes information such as the destination network address, the next-hop router that should be used to reach that destination, and the interface that the router should use to reach the next-hop router.
Now, let's go through each of the answer options:
A. Whether an ACL was applied inbound or outbound to an interface: This information is not typically found in the routing table. Access Control Lists (ACLs) are used to filter traffic based on criteria such as source and destination IP address, protocol, and port number. ACLs are typically applied to interfaces to control traffic entering or leaving a network, but they are not directly related to routing.
B. The EIGRP or BGP autonomous system: This information can be learned from the routing table. Routing protocols such as EIGRP (Enhanced Interior Gateway Routing Protocol) and BGP (Border Gateway Protocol) use autonomous system numbers (ASNs) to identify different networks and exchange routing information. The routing table will typically include the ASN for each route learned through these protocols.
C. Whether the administrative distance was manually or dynamically configured: This information is not typically found in the routing table. Administrative distance (AD) is a value used by routers to determine the trustworthiness of different sources of routing information. For example, if a router receives two different routes to the same destination network from two different sources, it will use the route with the lower AD value. However, the AD value itself is not typically included in the routing table.
D. Which neighbor adjacencies are established: This information is not typically found in the routing table. Neighbor adjacencies are established between routers running the same routing protocol in order to exchange routing information. The routing table will include information about the next-hop router for each route, but it does not typically include information about the neighbor adjacencies that were used to learn that route.
E. The length of time that a route has been known: This information can be learned from the routing table. Routers use various mechanisms to learn about routes, such as receiving updates from other routers or using a default route. The routing table will typically include the age of each route, which indicates how long the router has known about that route.
So, in summary, the two pieces of information that can be learned by viewing the routing table are:
