QUESTIONS CORRECT ANSWERS GRADED A PLUS
Question:
802.11h.
Answer:
Amendment to Wi-Fi standards that defines a Dynamic Frequency Selection (DFS) mechanism to
avoid interference with radar and cellular communications in the 5 GHz frequency band.
Question:
802.1p.
Answer:
IEEE standard defining a 3-bit (0 to 7) class of service priority field within the 802.1Q format.
Question:
802.1q.
Answer:
The 802.1Q protocol is often used to tag frames destined for different VLANs across trunk links.
Question:
802.1x.
Answer:
Standard for encapsulating EAP communications over a LAN (EAPOL) to implement port-based
authentication.
,Question:
802.3 ethernet standards.
Answer:
Standards developed as the IEEE 802.3 series describing media types, access methods, data rates,
and distance limitations at OSI layers 1 and 2 using xBASE-y designations.
Question:
access control list (ACL).
Answer:
The collection of access control entries (ACEs) that determines which subjects (user accounts, host
IP addresses, and so on) are allowed or denied access to the object and the privileges given
(read-only, read/write, and so on).
Question:
access point (AP).
Answer:
A device that provides a connection between wireless devices and can connect to wired networks,
implementing an infrastructure mode WLAN.
Question:
access/edge layer.
Answer:
Lowest tier in a hierarchical network topology acting as the attachment point for end systems.
Question:
active-active.
Answer:
High availability cluster configuration where all nodes are utilized continually.
,Question:
active-passive.
Answer:
High availability cluster configuration where one or more nodes are only utilized during failover.
Question:
ad hoc network.
Answer:
Type of wireless network where connected devices communicate directly with each other instead of
over an established medium.
Question:
address resolution protocol (ARP).
Answer:
Broadcast mechanism by which the hardware MAC address of an interface is matched to an IP
address on a local network segment.
Question:
addressing.
Answer:
Unique identifier for a network node, such as a MAC address, IPv4 address, or IPv6 address.
Question:
adjacent channel interference (ACI).
Answer:
Troubleshooting issue where access points within range of one another are configured to use
different but overlapping channels, causing increased noise.
, Question:
administrative distance (AD).
Answer:
Metric determining the trustworthiness of routes derived from different routing protocols.
Question:
administratively down.
Answer:
Switch or router port that has been purposefully disabled via the management interface.
Question:
advanced persistent threat (APT).
Answer:
Threat actors with the ability to craft novel exploits and techniques to obtain, maintain, and diversify
unauthorized access to network systems over a long period.
Question:
angled physical contact (APC).
Answer:
Fiber optic connector finishing type that uses an angled polish for the ferrule.
Question:
antenna type.
Answer:
Specially arranged metal wires that can send and receive radio signals, typically implemented as
either an omnidirectional or a unidirectional type.
