Which two statements describe features of an IPv4 routing table on a router? (Choose two.)​

Typically, in an IPv4 routing table on a router:

• Directly connected interfaces are identified by the route source code ‘C’ which stands for connected. They are present in the routing table because the router has an interface in those networks.
• Static routes are identified by the route source code ‘S’. This includes any static routes that have been manually configured on the router, such as a default static route.

However, directly connected interfaces having two route source codes ‘C’ and ‘S’ in the routing table is not a standard feature in IPv4 routing tables. In most cases, the ‘C’ code is used for directly connected networks, while ‘S’ is used exclusively for static routes. It’s possible that this statement is referring to a specific scenario where a static route has been configured for a network that is also directly connected, but this is not typical behavior as static routes are generally used to define routes to networks that are not directly connected.

With this in mind, the correct statements about features of an IPv4 routing table on a router, based on standard networking practices, include:

• If a default static route is configured in the router, an entry will be included in the routing table with source code ‘S’.

If your source is stating that directly connected interfaces will have two route source codes in the routing table: ‘C’ and ‘S’, then it’s important to consider the specific context or platform where this might be the case. It could be a particular configuration or a platform-specific feature that is not widely applicable across different router models or operating systems.
