    Failed routes are advertised with a metric of infinity.
    23. Which statement is true about the metrics used by routing protocols?
    A metric is a value used by a particular routing protocol to compare paths to remote networks.
    24. Which statement correctly describes a feature of RIP?
    RIP uses only one metric—hop count— for path selection.
    25. Refer to the exhibit. OSPF is used for the routing protocol and all interfaces are configured with the correct IP addresses and subnet masks. During testing, it is found that router R1 is unable to form an adjacency with R2. What is the cause of this problem?
    Both routers have been configured with different hello and dead intervals.

    28. A company is using static routes that are configured with an administrative distance of “1” on all routers in the network. The network administrator decides to introduce a dynamic routing protocol to reduce the manual configurations for the static routes. Which option identifies the correct procedure for the dynamic routing to take place in the network?
