| Q-1 What type of routing protocol maintains | | | | Q-6 What type of routing protocol is EIGRP? |
| neighbors? | | | | Answer: Hybrid |
| Answer- Link State | | | | Q-7 What is the range of values for |
| Q-2 what is the range of values for administrative | | | | administrative distance? |
| distance? | | | | Answer: 0-255 |
| Answer: 0-255 | | | | Q-8 What algorithm does OSPF use to compute |
| Q-3 Describe the difference between unicast, | | | | its route table? |
| multicast, and broadcast traffic? | | | | Answer: OSPF uses the shortest path first (SPF) |
| Answer: Unicast traffic flows from a single source | | | | algorithm, which is also known as the Dijkstra |
| to a single destination MAC address. Multicast | | | | algorithm. |
| traffic flows from a single source MAC address to | | | | Q-9 What is a stub area? |
| many destinations and uses a functional MAC | | | | Answer: A stub area is an area that does not |
| address. Broadcast traffic is from a single source | | | | accept routing updates from outside its |
| to all devices on the Ethernet segment. This is | | | | autonomous system. |
| specified by a destination MAC address of all ones. | | | | Q-10 What does the TTL field of an IP packet |
| Q-4 What are the four different Ethernet | | | | header do? |
| encapsulation types? | | | | Answer: The TTL field indicates the maximum |
| Answer: From the Cisco IPX encapsulation | | | | time that a packet can be on the network. Each |
| command they are ARPA, NOVELL-ETHER, SAP | | | | router that processes this packet decrements the |
| and SNAP | | | | TTL value by 1. If the value reaches zero, the |
| Q-5 What are the three main tasks of a | | | | packet is discarded from the network. The |
| transparent bridge? | | | | purpose of this field is to eliminate the possibility |
| Answer: Learning, Forwarding, Filtering | | | | of a packet endlessly traversing the network. |
