CERTIFICATION EVALUATION GUIDE 2026 FULL
SOLUTION
◉ carrier Ethernet. Answer: A WAN service that uses Ethernet links
as the access link between the customer and the service provider
◉ CDP. Answer: Cisco Discrovery Protocol. A media- and protocol-
independent device-discovery protocol that runs on most Cisco-
manufactured equipment, including routers, access servers, and
switches. Using CDP, a device can advertise its existence to other
devices and receive information about other devices on the same
LAN or on the remote side of a WAN
◉ CDP neighbor. Answer: A device on the other end of some
communications cable that is advertising CDP updates
◉ central office (CO). Answer: A term used by telcos to refer to a
building that holds switching equipment, into which the telco's cable
plant runs so that the telco has cabling from each home and business
into the building
◉ centralized control plane. Answer: An approach to architecting
network protocols and products that places the control plane
,functions into a centralized function rather than distributing the
function across the networking device
◉ Chef. Answer: A popular configuration management application,
which uses a server and a pull model with in-device agents
◉ Chef client. Answer: Any device whose configuration is being
managed by Chef
◉ Chef Cookbook. Answer: A set of recipes about the same kinds of
work, grouped together for easier management and sharing
◉ Cisco Access Control Server (ACS). Answer: A legacy Cisco product
that acts as a AAA Server
◉ Cisco AnyConnect Secure Mobility Client. Answer: Cisco software
product used as client software on user devices to create a VPN
◉ Cisco Open SDN Controller (OSC). Answer: A former commercial
SDN controller from Cisco that is based on the OpenDaylight
controller
◉ Cisco Prime. Answer: Graphical User Interface (GUI) software that
utilizes SNMP and can be used to manage your Cisco network
,devices. The term Cisco Prime is an umbrella term that encompasses
many different individual software products
◉ Cisco Prime Infrastructure. Answer: The name of Cisco's long-time
enterprise network management application
◉ Cisco Talos Intelligence Group. Answer: A part of Cisco Systems
company that works to perform security research on an ongoing
basis, in part to supply up-to-date data, like virus signatures, that
Cisco security products can frequently download
◉ Cisco VPN Client. Answer: See Cisco Anyconnect Secure Mobility
Client
◉ Class of Service (CoS). Answer: The informal term for the 3-bit
field in the 802.1Q header intended for marking and classifying
Ethernet frames for the purpose of applying QoS actions. Another
term for Priority Code Point (PCP)
◉ classification. Answer: The process of examining various fields in
networking messages in an effort to identify which messages fit into
certain predetermined groups (classes)
, ◉ classless addressing. Answer: A concept in IPv4 addressing that
defines a subnetted IP address as having two parts: a prefix (or
subnet) and a host
◉ client VPN. Answer: A VPN for which one endpoint is a user
device, like a phone, tablet, or PC. Also called a remote access VPN
◉ clock rate. Answer: The speed at which a serial link encodes bits
on the transmission medium
◉ clock source. Answer: On serial links, the device to which the
other devices on the link adjust their speed when using synchronous
links. With NTP, the external device or NTP server on which a device
bases its time
◉ clocking. Answer: The process of supplying a signal over a cable,
either on a separate pin on a serial cable or as part of the signal
transitions in the transmitted signal, so that the receiving device can
keep synchronization with the sending device
◉ Clos network. Answer: A term for network topology that
represents an ideal for a switch fabric and named after Charles Clos,
who formalized the definition. Also called a spine-leaf network
