A network engineer is configuring a point-to-point link between two routers on
a WAN network. The link is intended to support a critical real-time application
that requires continuous bidirectional data flow without any transmission
delays.
Which type of communication should the engineer configure on the point-to-
point link to meet the application's requirements?
A. Half-duplex communication with Quality of Service (QoS) prioritization to
ensure real-time data is transmitted without delay.
B. Half-duplex communication, because it allows for two-way communication
with a guaranteed level of bandwidth.
C. Full-duplex communication with multiple cables to increase the bandwidth
and support the high data rate required by the application.
D. Full-duplex communication, as it supports simultaneous bidirectional data
flow, which is essential for real-time applications. - ANSWER-D
At Layer 4 of the OSI model, which mechanism is responsible for ensuring
reliable data delivery between hosts?
A. The use of port numbers to identify different types of network traffic
B. The encryption of data to prevent unauthorized access during transmission
,C. The implementation of flow control and error-checking protocols
D. The assignment of IP addresses to route packets to their destination -
ANSWER-C
A network technician wants to create efficiencies in network traffic by
implementing a device which applies microsegmentation by establishing a point-
to-point link between any two network nodes.
Which of the following should they implement?
A. Access Point
B. Hub
C. Layer 2 switch
D.Bridge - ANSWER-C
Which function of the SOHO router is responsible for allocating a unique IP
address to each host that connects to it?
A. Network Address Translation (NAT)
B. Virtual Private Network (VPN)
C. Dynamic Host Configuration Protocol (DHCP)
D. Quality of Service (QoS) - ANSWER-C
You are a network administrator troubleshooting an issue where a client
computer is not properly receiving and handling different types of network
traffic.
,You suspect that the problem lies with the de-multiplexing process at the
Transport layer of the OSI model.
Which of the following scenarios would MOST likely indicate a problem with the
de-multiplexing process at the receiving host? (Select two.)
A. The client computer receives a VoIP packet and correctly processes it as audio
data.
B. The client computer is experiencing slow network speeds due to congestion.
C. The client computer is unable to establish a connection to the web server on
port 80.
D. The client computer is not receiving any packets from the network.
E. The client computer receives an email data packet but processes it as web
traffic. - ANSWER-A, E
You want to implement a fault-tolerant topology as you connect routers on your
wide area network.
Which of the following topologies BEST meets your requirements?
A. Bus
B. Mesh
C. Ring
D. Star - ANSWER-B
A network administrator notices that communication to a particular node in a
star topology network consistently fails.
, The node is located at a significant distance from the central switch, further than
any other node on the network. The administrator suspects that the distance
may be causing signal degradation.
What is the MOST appropriate solution to resolve this issue?
A. Increase the bandwidth of the central switch.
B. Use a repeater to strengthen the signal over the extended distance.
C. Replace the switch with a hub to increase signal strength.
D. Implement a mesh topology for the entire network. - ANSWER-B
Which of the following layers are part of the four-layer hierarchy of the Internet
model? (Select two.)
A. Presentation Layer
B. Application Layer
C. Internet Layer
D. Physical Layer
E. Session Layer - ANSWER-B, C
Which of the following statements accurately describe characteristics of the
decimal numbering system? (Select two.)
A. Each digit can have one of ten possible values.
B. Each digit can have one of two possible values.
