Module 10 Review
1
What is the address that is
changed when a frame is
received at a router interface?
• MAC address
2
What OSI layer offers reliable,
connection-oriented data
communication services?
• transport
3
What IP packet field will
prevent endless loops?
• time-to-live
4
Which processes occur each time a
packet is switched from one router
interface to another?
• encapsulation
• de-encapsulation
5
Which of the following are
routed protocols?
(Choose three.)
•
•
•
•
•
•
IP
BGP
XNS
RIP
OSPF
DECnet
6
How would you describe
path determination at the
network layer?
• router compares available
routing table information to
select the best path
7
What do routers use to exchange
topological information?
• routing protocols
8
What are 3 metrics used with
routing protocols?
• delay
• cost
• reliability
9
What are 2 link-state
routing protocols?
• OSPF
• IS-IS
10
What are 3 benefits of
subnetting?
• smaller broadcast domains
• low-level security provided
• increased address flexibility
11
Given a host with the IP address
176.42.75.23 and a default subnet mask,
to which network does the host belong?
• 176.42.0.0
12
A small company has a class C network
license and needs to create eight usable
subnets, each subnet capable of
accommodating at least 14 hosts. What
is the appropriate subnet mask?
• 255.255.255.240
13
How many bits are available for
Class B host IP addresses using
the default subnet mask?
• 16
14
What is true concerning the host
bits of the network address and
the broadcast address?
• Host bits of the network
address are all equal to 0.
• Host bits of the broadcast
address are all equal to 1.
15
How many usable subnets are
created by applying the subnet mask
255.255.255.0 to a Class B network?
• 254
16
What do you call the process that routers
use to determine the subnet network
address based upon a given IP address
and subnet mask?
• binary ANDing
17
Which statements describe the
effects broadcast storms have on
networking equipment?
(Choose two.)
• Switches forward broadcast storms.
• Switches block broadcasts.
• Switches handle broadcasts in similar fashion to
routers.
• Routers can be segmented to increase bandwidth.
• Routers block broadcasts.
• Routers and switches provide security and
bandwidth control to overcome broadcast storms.
18
What information is listed in
routing tables?
(Choose three.)
•
•
•
•
•
•
Protocol types
Encapsulations
Metrics
MAC addresses
Inbound interfaces
Outbound interfaces
19
What is the routing metric for
RIPv1?
• hop
20
Which statements describe Layer 2
and Layer 3 packet address changes
as the packet traverses from router
to router? (Choose two.)
• Layer 3 header is removed and replaced at
every Layer 3 device.
• Layer 2 and Layer 3 addresses do not
change when the packet traverse.
• Layer 3 source and destination addresses
do not change when the packet traverse.
• Layer 2 frame header and trailer are
removed and replaced at every Layer 3
device.
• Layer 2 source and destination addresses
do not change when the packet travels.
21
What are two differences
between routers and
switches?
• Routers make forwarding decisions
using IP addresses, but switches
use MAC addresses.
• Switches forward broadcasts and
routers do not.
22
What are two functions of a
routing protocol?
• provides processes for sharing
route information
• allows a router to communicate
with other routers
23
How many usable class C
subnetworks are created with a
subnet mask of 255.255.255.240?
• 14
24
Company XYZ uses a network address of
192.168.4.0. It uses the mask of
255.255.255.192 to create subnets. What
is the maximum number of usable hosts
in each subnet?
• 62
25
Which are the network and broadcast
addresses when given an IP host
address of 198.101.6.55/27?
• Network = 198.101.6.32
• Broadcast = 198.101.6.63
