Microsoft Certified Systems Engineer (MCSE) Question:
Describe the basics of the internet routing.
Answer:
When a source sends a packet to a destination, this packet has a specific path or route it follows. Different routing protocols are used to find the shortest path to the destination. The protocols maintain routing tables. Routing tables consist of a set of rules used to determine where these packets will travel. When a packet is received, a network device examines the packet and matches it to the routing table entry providing the best match for its destination. The packet keeps hopping until it reaches its destination.
