WGU C724 Exam Review Questions with Verified
Correct Answers
Jitter
bufferboat can cause packet delay variation
Router
is a networking device used to pass packets to the next network node until the packets reach
the ultimate destination.
Core Routers
is used to connect the enterprise to the Internet in the backbone in order to handle large
amounts of data traffic.
Edge (boundary) Router
transfers data packets between one or more LANs and an asynchronous transfer mode (ATM)
network.
Network Bridge
is a computer networking device that creates a single aggregate network from multiple
communication networks or network segments.
Bridging
allows multiple different networks to communicate independently while remaining separate.
The Four Types of Network Bridging
Simple bridging, multiport bridging, learning or transparent bridging, and source route
bridging.
,Peer-to-Peer Networks
offer a faster connection between nodes, because information is stored locally on each
individual computer and not one central server.
Mesh Network
is a network topology in which each node relays data for the network.
Network Management Application
is a computer software tool that gathers traffic data from the network to ensure network
performance is optimized.
Software-Defined Networking (SDN)
is an approach to computer networking that allows network administrators to
programmatically initialize, control, change, and manage network behavior dynamically via
open interfaces and abstraction of lower-level functionality.
Hypervisor
is an expensive virtual machine monitoring application used by large organizations to
improve computer network performance without having to physically change the network.
Next-Generation Firewall (NGFW)
is an integrated network platform that is a part of the third generation of firewall technology,
combining a traditional firewall with other network device filtering functionalities, such as an
application firewall using in-line deep packet inspection (DPI), an intrusion prevention
system (IPS).
Transmission Control Protocol (TCP Protocol)
consists of four abstraction layers: application, transport, Internet, and network access.
,Application Layer
is where applications create and communicate user data to other applications on the same or
another host.
Open System Interconnection (OSI)
is the foundation for data communication protocols and is an international standard that
governs the development of data communication protocols (consists of seven layers).
The Seven Layers of OSI
application, presentation, session, transport, network, data link, and physical.
Data Packet Switching
these are sent out and travel across the Internet in random order.
Circuit Switching
the path is decided before the transmission occurs. ideal for communications that require data
to be transmitted in real-time; a constant connection is required before transmission begins.
used for VoIP, video conferencing, video, and multimedia communications.
Data Packets
have the destination IP address, the actual information to be sent, which can be parceled into
many other packets, and error detection in case transmission fails.
Convergence
The ability for a telecommunication network to carry voice, data, and video.
Frame Relay
is a packet switching network protocol used to establish circuit switching for voice or video.
, Converged Network
is one in which voice, data, and video are all carried on the same network, with the business
no longer using a traditional telephone network.
Multiplexing
is the process in which multiple signals are combined into one signal, which is then
transmitted over a shared medium.
Analog Signals
are continuous electrical waveform signals.
Digital Signals
discrete, binary, noncontinuous electrical waveforms.
Near Field Communication (NFC)
is a set of communication protocols that enable two electronic devices, one of which is
usually a portable device such as a smartphone, to establish communication by bringing them
within 4 cm (1.6 in) of each other.
Electronic Communication
Email, instant messaging, audio and video communications, and unified communications.
Web Page, File Storage, and Hosting
Repositories of information, storage for retrieval or archival of documents, programs,
applications, and consumables such as audio and video.
