IP Routing 3

Question 1


Floating static routes are static routes that have an administrative distance greater than the administrative distance (AD) of another static route or dynamic routes. By default a static route has an AD of 1 then floating static route must have the AD greater than 1. Floating static route has a manually configured administrative distance greater than that of the primary route and therefore would not be in the routing table until the primary route fails.

Question 2


A host route for IPv4 has the mask /32, and a host route for IPv6 has the mask /128. If an IPv4 address is configured with a mask of /32 on an interface of the router, which is typical for loopback interfaces, the host route appears in the routing table only as connected (for example in the routing table we will see this line: “C is directly connected, Loopback0”.

Question 3


If the IP address exists in the routing table then we can say the local router knew the way to reach that destination. But this question wants to ask if the destination has communicated to the local router or not (“an IP address is known to a router”). Maybe it is a tricky question.

Question 4


In all the way on the path, the source and destination IP addresses never change, only the source and destination MAC address are changed on each segment.

    Q5) When is a routing table entry identified as directly connected?
    A. When the local router is in use as the network default gateway
    B. When the network resides on a remote router that is physically connected to the local router
    C. When an interface on the router is configure with an ip address and enabled
    D. When the route is statically assigned to reach a specific network

    Why answer is not B) and in the .pdf is given C) as the right question ?
