QUESTION NO: 1
A technician needs to limit the amount of broadcast traffic on a network and allow different
segments to communicate with each other. Which of the following options would satisfy these
requirements?
A.
Add a router and enable OSPF.
B.
Add a layer 3 switch and create a VLAN.
C.
Add a bridge between two switches.
D.
Add a firewall and implement proper ACL.
Answer: B
Explanation:
We can limit the amount of broadcast traffic on a switched network by dividing the computers into
logical network segments called VLANs.
A virtual local area network (VLAN) is a logical group of computers that appear to be on the same
LAN even if they are on separate IP subnets. These logical subnets are configured in the network
switches. Each VLAN is a broadcast domain meaning that only computers within the same VLAN
will receive broadcast traffic.
To allow different segments (VLAN) to communicate with each other, a router is required to
establish a connection between the systems. We can use a network router to route between the
VLANs or we can use a ‘Layer 3’ switch. Unlike layer 2 switches that can only read the contents of
the data-link layer protocol header in the packets they process, layer 3 switches can read the (IP)
addresses in the network layer protocol header as well.

QUESTION NO: 2
The network install is failing redundancy testing at the MDF. The traffic being transported is a
mixture of multicast and unicast signals. Which of the following would BEST handle the rerouting
caused by the disruption of service?
A.
Layer 3 switch
B.
Proxy server
C.
Layer 2 switch
D.
Smart hub
Answer: A
Explanation:
The question states that the traffic being transported is a mixture of multicast and unicast signals.
There are three basic types of network transmissions: broadcasts, which are packets transmitted
to every node on the network; unicasts, which are packets transmitted to just one node; and
multicasts, which are packets transmitted to a group of nodes. Multicast is a layer 3 feature of IPv4
& IPv6. Therefore, we would need a layer 3 switch (or a router) to reroute the traffic. Unlike layer 2
switches that can only read the contents of the data-link layer protocol header in the packets they
process, layer 3 switches can read the (IP) addresses in the network layer protocol header as well.

C.
Content filter
D.
Load balancer
Answer: B
Explanation:
A firewall is a system designed to prevent unauthorized access to or from a private network.
Firewalls are frequently used to prevent unauthorized Internet users from accessing private
networks connected to the Internet, especially intranets. Firewalls use ACLs (access control lists)
to determine which traffic is allowed through the firewall. All traffic entering or leaving the intranet
passes through the firewall, which examines each message and blocks or allows the message
depending on rules specified in the ACL. The rules in the ACL specify which combinations of
source IP address, destination address in IP port numbers are allowed.
QUESTION NO: 4
Which of the following is used to define how much bandwidth can be used by various protocols on
the network?
A.
Traffic shaping
B.
High availability
C.
Load balancing
D.
Fault tolerance
