Client-Server - CORRECT ANSWER-You've implemented a network where hosts are
assigned specific roles, such as file sharing and printing roles. Other hosts access those
resources, but they don't host services of their own.
Which type of network do you have?
Metropolitan Area Network (MAN) - CORRECT ANSWER-Which of the following
geographic network types is typically managed by a city as a public utility?
Peer-to-peer - CORRECT ANSWER-You've implemented a network where each device
provides all other devices on the network with access to shared files.
Which type of network do you have?
Messages are broadcast to all devices connected to the network. - CORRECT
ANSWER-You have a network that uses a logical bus topology. How do messages
travel through the network?
Messages travel from one device to the next until they reach the destination device. -
CORRECT ANSWER-You have a network that uses a logical ring topology. How do
messages travel through the network?
Partial mesh - CORRECT ANSWER-Your manager has asked you to implement a wired
network infrastructure that will accommodate failed connections. You don't have a large
budget, so you decide to provide redundancy for only a handful of critical devices.
Which of the following network topologies should you implement?
Bus - CORRECT ANSWER-Which of the following topologies connects all devices to a
trunk cable?
Mesh - CORRECT ANSWER-Your manager has asked you to implement a network
infrastructure that will accommodate failed connections.
Which of the following network topologies provides redundancy for a failed link?
Ring - CORRECT ANSWER-Which of the following topologies connects each device to
a neighboring device?

-Packets
Data Link layer
-Frames
Physical layer
-Bits - CORRECT ANSWER-During TCP/IP communication between two network hosts,
information is encapsulated on the sending host and decapsulated on the receiving host
using the OSI model.
Match the information format on the left with the appropriate layer of the OSI model on
the right.

with the corresponding layer of the OSI model on the right. Each option on the left can
be used more than once.
Encapsulation - CORRECT ANSWER-Which of the following is the process of breaking
a message into packets, adding controls and other information, and then transmitting
the message through the transmission medium?
Checksum error detection - CORRECT ANSWER-What is the purpose of a frame check
sequence (FCS) footer?

When the router's routing table doesn't contain the MAC addresses of devices on the
local LAN that they need to forward frames to. - CORRECT ANSWER-When does a
router use ARP?
Hosts use ARP to resolve known IP addresses into MAC addresses. - CORRECT
ANSWER-Routing data between computers on a network requires several mappings
between different addresses. Which of the following statements is true?
ARP - CORRECT ANSWER-During network transmission, data is transferred to various
routers, which forward the data to the appropriate network. If the source and destination
network addresses reside on the same network, which protocol is used to determine the
destination IP's MAC address?
SYN/ACK - CORRECT ANSWER-TCP is a connection-oriented protocol that uses a
three-way handshake to establish a connection to a system port. Computer 1 sends a
SYN packet to Computer 2. Which packet does Computer 2 send back?
ICMP (Internet Control Message Protocol) - CORRECT ANSWER-Which of the
following protocols allows hosts to exchange messages to indicate problems with
packet delivery?
