Can use some help with Computer Networking, with a focus on routing protocols. Part A: Which of these routing protocols is the oldest? (Please select from one of the four options)1. RIP2. BGP3. OSPF4. IGRPPart B: Some routing protocols determine the best route to take based on how many routers a packet must traverse to reach its destination. Which metric measures this? (Please select from one of the four options)1. Hop count2. Latency3. MTU4. Link state

A. RIP

B. Hop count

Explanation:

RIP or routing information protocol is a distant vector protocol that uses the hop count as a metric to determine the best path for packet switching to the destination network address.

Hop count is a metric used in the routing packet. It evaluates the distance of the path to the destination host by the number of routers encountered in the transversal.

since it can be assumed that what aslam is making is a template by compiling all the commonly used excel formatting in several worksheets in an excel document, aslam can choose to save it using the .xltx or .xltm format instead. thus, aslam can distribute the templates he has made to his team members in an easier manner.
