Which two statements about static route configuration are true? (Choose two)

The correct answer is C. The redistribute static command will redistribute classful networks into OSPF. F. The permanent key word allows the route to remain in the route table if the interface goes down.. Static routes can be redistributed into dynamic routing protocols like OSPF, and the 'permanent' keyword ensures they persist in the routing table even if their associated interface goes down.

Why each option

Static routes can be redistributed into dynamic routing protocols like OSPF, and the 'permanent' keyword ensures they persist in the routing table even if their associated interface goes down.

AThey add to the number of routes in the routing table.

While static routes do add to the routing table, this statement is too general and not one of the two best options for describing characteristics.

BThe distance command modifies the administrative distance

The `distance` command (or `administrative-distance`) modifies the administrative distance, but it's not a statement *about* static route configuration itself, rather a parameter of it.

CThe redistribute static command will redistribute classful networks into OSPF.Correct

The `redistribute static` command is used in dynamic routing protocols, such as OSPF, to inject static routes into their routing tables, allowing them to be advertised to other routers in the network. This integrates static routing information into the dynamic routing domain.

DThey add significant overhead to the router CPU.

Static routes generally add minimal overhead to the router CPU compared to dynamic routing protocols, as they do not require continuous processing for route updates or neighbor discovery.

EThe ip route static bfd command is used for BFD peer discovery.

The `ip route static bfd` command is used to enable BFD (Bidirectional Forwarding Detection) for static routes, which is a specific feature for faster link failure detection, not just for general BFD peer discovery.

FThe permanent key word allows the route to remain in the route table if the interface goes down.Correct

The `permanent` keyword, when used with a static route, instructs the router to keep the route in the routing table indefinitely, even if the next-hop interface or IP address becomes unavailable. This is particularly useful for scenarios requiring resilient routing paths or specific traffic handling in the event of an interface failure.
