QUESTION 1:
Which one of the following characteristics is true regarding the use of hubs and
switches?
A. Hubs can have their ports be configured with VLANs
B. Using hubs is costly with regard to bandwidth availability.
C. Switches can not forward broadcasts.
D. Switches are more efficient than hubs in processing frames.
E. Switches increase the number of collision domains in the network.
Answer: E
Explanation: Switches increases the number of collisions domains in the network.
Switches that are configured with VLANs will reduce the size of the collision
domains by increasing the number of collision domains in a network, but making
them smaller than that of one big, flat network.
Incorrect Answers:
A. Switches are capable of VLAN configurations, but hubs are not.
B. Hubs are generally the least costly method possible to connect multiple devices
together in a network.
C. Switches forward broadcasts and multicasts, by default, to all ports within the same
VLAN. Only routers block all broadcast traffic by default.
D. Switches and hubs can be equally efficient in processing frames, in theory. In practice,
switches are generally more efficient as they usually have more CPU and memory
allocated to them, and are generally much more expensive than a simple hub.
QUESTION 2:
When comparing and contrasting the similarities and differences between bridges
and switches, which of the following are valid statements? Choose all the valid
answer choices)
A. Bridges are faster than switches because they have fewer ports.
B. A switch is a multiport bridge,
C. Bridges and switches learn MAC addresses by examining the source MAC address of
each frame received.
D. A bridge will forward a broadcast but a switch will not.
E. Bridges and switches increase the size of a collision domain.
F. None of the above statements are true.
Answer: B, C
Explanation:
Both bridges and switches build the bridge table by listening to incoming frames and
examining the source MAC address in the frame.
Switches are multiport bridges that allow you to create multiple broadcast domains. Each
broadcast domain is like a distinct virtual bridge within a switch.
Incorrect Answers:
A. Switches are generally faster than bridges. Bridges also do not necessarily have fewer
ports than switches.
D. Both bridges and switches will forward broadcast and multicast traffic, assuming that
the traffic remains in the same VLAN.
E. The use of VLANs in a switch can decrease the size of the collision domain, by
creating additional, smaller collision domains.
QUESTION 3:
Which of the following correctly describe the various functions and virtues of a
router? (Select all valid answer choices)
A. Packet switching
B. Collision prevention on a LAN segment.
C. Packet filtering
D. Broadcast domain enlargement
E. Broadcast forwarding
F. Internetwork communication
G. None of the above
Answer: A, C, F
Explanation:
The main function of a router is to connect different, separated networks together. In
doing so, switching packets from one network to another is a primary function, along
with providing for communication between networks. As an additional feature, routers
are capable of providing filtering on a network address and application port level, so
choice C is also correct.
Incorrect Answers:
B. Routers can indeed be used to segment a network separate a collision domain, since
routers do not forward LAN broadcasts and multicasts to other interfaces. However,
routers alone can not prevent all collisions from occurring on any given LAN segment.
D. Routers actually segment LANs into smaller broadcast domains.
E. Routers do not forward broadcast and multicast traffic out the additional interfaces by
default. Unless bridging or IP helpers are configured on the router, LAN broadcasts are
blocked at the router level.
QUESTION 4:
The LAN needs are expanding at the Certkiller corporate office, which is quickly
growing. You are instructed to enlarge the area covered by a single LAN segment on
the Certkiller network.
Which of the following are layer 1 devices that you can use? (Choose all that apply.)
A. A switch
B. A router
C. A network adapter card
D. A hub
E. A repeater
Answer: D, E
Explanation:
A hub simply repeats the electrical signal and makes no attempt to interpret the electrical
signal (layer 1) as a LAN frame (Layer 2). So, a hub actually performs OSI layer 1
functions, repeating an electrical signal, whereas a switch performs OSI layer 2
functions, actually interpreting Ethernet header information, particularly addresses, to
make forwarding decisions. Hubs can be used to increase the number of stations that can
be supported on a LAN.
Because the repeater does not interpret what the bits mean, but does examine and
generate electrical signals, a repeater is considered to operate at Layer 1. Repeaters can
be used to physically extend the LAN to greater distances.
QUESTION 5:
Cisco is the leader in the router market space. What basic functions do their routers
perform in a network? (Choose two)
A. The microsegmentation of broadcast domains
B. Path selection
C. Packet switching
D. Bridging between LAN segments
E. Access layer security
F. VLAN membership assignment
G. Application optimization
Answer: B, C
Explanation:
The primary functions of a router are: Packet Switching and Path Selection. It is the
routers job to determine the best method for delivering the data, and switching that data
as quickly as possible.
