The Cisco CCNA certification (Cisco Certified Network Associates) is an introductory level exam for those relatively new to Cisco networking. The CCNA exam by Cisco systems was designed for the candidates who can install, configure and administer small to medium sized LANs and WANs. The CCNA is a prerequisite for the some higher level certifications like the CCNP. The CCNA exam is valid for three years. Job roles for the individuals who are CCNA certified include network administrators, system managers, and network consultants.

QUESTION 116:
640-802
Www.actualtest.org – The Power of Knowing
Within the PassGuide office, The Sales and Production networks are separated by a
router as shown in the diagram below:
Which of the following statements most accurately describes the characteristics of
the above networks broadcast and collision domains? (Select the two best answer
choices)
A. There are two broadcast domains in the network.
B. There are four broadcast domains in the network.
C. There are six broadcast domains in the network.
D. There are four collision domains in the network.
E. There are five collision domains in the network.
F. There are seven collision domains in the network.
Answer: A, F
Explanation:
In this network we have a hub being used in the Sales department, and a switch being
used in the Production department. Based on this, we have two broadcast domains: one
for each network being separated by a router. For the collision domains, we have 5
computers and one port for E1 so we have 6 collision domains total because we use a
switch in the Production Department so 5 are created there, plus one collision domain for
the entire Sales department because a hub is being used.
QUESTION 117:
The PassGuide corporate LAN consists of one large flat network. You decide to
segment this LAN into two separate networks with a router. What will be the affect
of this change?
640-802
Www.actualtest.org – The Power of Knowing
A. The number of broadcast domains will be decreased.
B. It will make the broadcasting of traffic between domains more efficient between
segments.
C. It will increase the number of collisions.
D. It will prevent segment 1’s broadcasts from getting to segment 2.
E. It will connect segment 1’s broadcasts to segment 2.
Answer: D
Explanation
A router does not forward broadcast traffic. It therefore breaks up a broadcast domain,
reducing unnecessary network traffic. Broadcasts from one segment will not be seen on
the other segment.
Incorrect Answers:
A. This will actually increase the number of broadcast domains from one to two.
B. All link level traffic from segment one to segment two will now need to be routed
between the two interfaces of the router. Although this will reduce the traffic on the LAN
links, it does also provide a less efficient transport between the segments.
C. Since the network size is effectively cut into half, the number of collisions should
decrease dramatically.
E. Broadcasts from one segment will be completely hidden from the other segment.
QUESTION 118:
You want to influence the root bridge selection within the PassGuide LAN. Which
two values are used by spanning tree protocol to elect a root bridge? (Choose two.)
A. Amount of RAM
B. Speed of the links
C. IOS Version
D. MAC Address
E. Bridge Priority
F. IP Address
G. Router ID
Answer: D, E
Explanation:
Switch having lowest bridge ID will become the root bridge. The bridge ID is how STP
keeps track of all the switches in the network. It is determined by a combination of the
bridge priority (32,768 by default on all Cisco switches) and the base MAC address. The
bridge with the lowest bridge ID becomes the root bridge in the network.

QUESTION 119:
A PassGuide Ethernet switch receives a unicast frame with a destination MAC that
IS listed in the switch table. What will this switch do with the frame?
A. The switch will forward the frame to a specific port
B. The switch will forward the frame to all ports except the port on which it was received
C. The switch will return a copy of the frame out the source port
D. The switch will not forward unicast frames
E. The switch will remove the destination MAC from the switch table
F. None of the above.
Answer: A
Explanation:
How Does the Switch Find Host MACs?
Let’s use the diagram below to help us understand how address learning process takes
place.
Let’s assume that we have just powered on the switch. It has nothing in its MAC table.
We connect the cables from the hosts on the switch interfaces as shown in the diagram.
Host A initiates a connection towards Host D, and the following takes place:
1. Host A (interface fe0/0) sends a frame to Host D (MAC address:0000.43c5.334c).
2. The switch inspects the Source Address in the frame and notes in its table the MAC
address of Host A along with the Interface number from which the frame originated.
640-802
Www.actualtest.org – The Power of Knowing
3.
The switch inspects the Destination Address in the frame. Since it does not have Hosts D
MAC address in its table, it constructs a broadcast frame and forwards out all interfaces
except the interface from where the original frame arrived.
4. Host D identifies itself as the expected recipient and responds back to Host
A. The
switch receives the respond frame on interface fe0/11 and places the SA in its table along
with the interface number where the frame came from.
5. From now on, further communication between the two hosts will be switched to
the appropriate interfaces based on the MAC tables entries.
This process takes place every time a new host is attached on the switch and initiates
traffic. The switch tries to keep its MAC table up-to-date, therefore if some hosts do not
initiate traffic for a certain amount of time, the switch removes them from its table and
reinserts them when they begin sending traffic.

QUESTION 120:
In which circumstance are multiple copies of the same unicast frame likely to be
transmitted in the PassGuide Switched LAN?
A. During high traffic periods
B. In an improperly implemented redundant topology
C. After broken links are re-established
D. When upper-layer protocols require high reliability
E. When a dual ring topology is in use
F. None of the above
