router
The external routing protocol used on the Internet is _______.
Border Gateway Protocol (BGP)
The variety of _______________ protocols would include RIP, OSPF, EIGRP, and BGP.
dynamic routing
A(n) _______________ is normally entered manually into a router.
static route
A(n) _______________ connects one Autonomous System to another Autonomous System.
edge router
_______ is a routing protocol that updates routing tables every 30 seconds, resulting in overloaded network traffic.
RIPv1
When all routers can communicate with each other efficiently, they are said to have reached _______________.
convergence
A network at the top of the Internet governed by a single protocol—BGP—is known as a(n) _______________.
Autonomous System (AS)
You can use the _______________ utility to troubleshoot routing problems.
traceroute
______ uses IP addresses and port numbers to enable many internal computers to share a single public IP address.

If specialty accounting software being used at your company requires that packet headers remain unchanged, which item cannot be used on your network?
A. RIP
B. NAT
C. OSPF
D. traceroute
NAT
How does a router use a routing table to determine over which path to send a packet?
A. The first line in the routing table is used if the path is available; otherwise, the router tries the next line down, and so on.
B. The last line in the routing table is used if the path is available; otherwise, the router tries the next line up, and so on.
C. After examining all rows in the routing table, the router sends the packet along the path with the highest metric.
D. After examining all rows in the routing table, the router sends the packet along the path with the lowest metric.
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?
A. Static NAT
B. Dynamic NAT
C. Pooled NAT
D. SecureNAT
