Chapter 7 - Routing Flashcards
A device called a(n) _______________ is also called a Layer 3 switch.
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.
Port Address Translation (PAT)
How many IP addresses should a router have?

B. One or more
C. Two
D. Two or more
two or more
Choose the Cisco Systems routing protocol from the following items.
A. BGP
B. EIGRP
C. RIP
D. OSPF
EIGRP
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
Static NAT
What technology enables you to designate a specific local address for various network services?
A. Dynamic NAT
B. Port Address Translation
C. Port forwarding
D. Port filtering
Port forwarding
How is the distance between routers measured with RIP?
A. In meters
B. In hops
C. In routes
D. In segments
In hops
Which of the following is a distance vector routing protocol?
A. RIP
B. OSPF
C. BGP
D. ASN
RIP
Which of the following are benefits of RIPv2 over RIPv1? (Select two.)
A. Longer convergence times
B. Support for authentication
C. Support for VLSM
D. Support for metrics
Longer convergence times, Support for VLSM
Which of the following router protocols uses link state advertisements?
A. RIPv1
B. RIPv2
C. OSPF
D. BGP
OSPF
Why are link state protocols more efficient than RIP?
A. Entire routing tables are updated on a stricter schedule.
B. They forward only changes to individual routes instead of forwarding entire routing tables.
C. Packets can be sent along multiple routes at the same time.
D. Link state can send larger packets.
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?
A. It floods the network with Hello packets as it looks for other OSPF routers.
B. It floods the network by requesting routing tables from every computer on the network.
C. It is unavailable for several hours as it builds its default routing table.
D. It runs a self-test to determine if it should run in hybrid mode (RIP and OSPF) or native mode (OSPF only).
It floods the network with Hello packets as it looks for other OSPF routers.
How can you connect a PC directly to a router for configuration purposes? (Select two.)
A. Parallel cable
B. USB cable
C. Crossover cable
D. Rollover cable
crossover and rollover
Once you have made a physical direct connection to a router, what utility/program can you use to issue commands and instructions? (Select three.)
A. PuTTY
B. HyperTerminal
C. IOS
D. Web browser
