How many IP addresses should a router have? | Two or more |
Choose the Cisco Systems proprietary routing protocols from the following items. | Answers B and C.... B is EIGRP and C is IGRP |
If specialty accounting software being used at your company requires that packet headers remain unchanged, which item cannot be used on your network? | NAT |
How does a router use a routing table to determine over which path to send a packet? | D) After examining all rows in the routing table, the router sends the packet along the path with the lowest metric. |
Which version of NAT maps a single routable IP address to a single network node? | Static NAT |
What technology enables you to designate a specific local address for various network services? | C) Port forwarding |
How is the distance between routers measured? | B) In hops |
Distance vector routing protocols include which of the following? | Answers A and C A) RIP C) BGP |
Which of the following are benefits of RIPv2 over RIPv1? | Answers B and C B) Support for authentication C) Support for VLSM |
What is one way in which Autonomous Systems differ from typical Ethernet networks? | D)They do not use IP addresses. |
Why are link state protocols more efficient than RIP? | They forward only changes to individual routes instead of forwarding entire routing tables. |
What happens when you first connect and turn on an OSPF router? | It floods the network with Hello packets as it looks for other OSPF routers. |
Which of the following is a valid Area ID for an Area 0 backbone? | B) 0.0.0.0 |
How can you connect directly to a router for configuration purposes? | E) Answers B, C, and D B) USB cable C) Crossover cable D) Rollover cable |
Once you have made a physical direct connection to a router, what utility/program can you use to issue commands and instructions? | E) Answers A, B, and D A) PuTTY B) HyperTerminal D) Internet Explorer |
The most common form of Nat that handles a one-to many connection, using port numbers to map traffic from specific machines in the network. | PAT |
Can share a pool of routable IP addresses with multiple computers. | Dynamic NAT |
Routing Metrics -Determining A metric | 1. Maximum transmission units-determining the largest frames a technology can handle. ==== 2. Cost-Some connections cost more than others. ==== 3. Bandwidth-Some connections handle more data than others. ==== 4. Latency-stuff that slow the n |
------Routing protocals calculate the total cost to get to a particular network id and compare that cost to the total cost of all other routes to get to that same network id. | Distance Vector |
A ---- is any piece of hardware that forwards packets based on their destination ip address. | Router |
Destination Lan IP | Destination Lan IP A defined network Id. Every network id directly connected to one of the router's ports is always listed here. |
To define a network Id, you need a subnet mask | Subnet mask |
