Questions with Verified Answers
A network firewall analyzes each packet against a set of security criteria before
deciding to allow or block. This approach is known as: - CORRECT ANSWER Rule-
Based Access Control
A stateful firewall uses Stateful Packet Inspection to protect the network. How
does this type of firewall operate? - CORRECT ANSWER A stateful firewall that
compares all inbound traffic to ensure there is a prior outbound request.
While setting up a Wi-Fi network, the network administrator decides to use a
wireless encryption method that includes each device using a unique encryption
key. Which protocol is the administrator choosing? - CORRECT ANSWER WPA3
Which wireless infrastructure mode uses a central wireless device, such as a
wireless router or wireless access point? - CORRECT ANSWER Infrastructure
In a scenario where an organization groups employees with similar job functions
together and assigns identical permissions to each group, what type of access
control is being used? - CORRECT ANSWER Role-based
An organization is looking to utilize a Firewall that can help prevent attacks, such
as SQL Injection and Buffer Overflow attacks. Which type of Firewall can assist in
this situation by inspecting the network payload of each packet? - CORRECT
ANSWER Application Firewall
What attack involves sending disassociation frames to wireless devices, thus
disconnecting clients from the wireless network? - CORRECT ANSWER
Deauthentication attack
What is a proxy server? - CORRECT ANSWER A server that authenticates and
makes request on behalf of another system on the network
, An organization is deploying a sophisticated firewall that examines both individual
packets and their collective grouping. What type of access control does this
represent? - CORRECT ANSWER Context-based
Which type of Firewall inspects the source and destination IP address and Port
address (contained in the packet header) for every single packet that enters and
leaves the network? - CORRECT ANSWER Packet Filtering Firewall

set or change permissions? - CORRECT ANSWER The owner of the resource
Firewall - CORRECT ANSWER A part of a computer system or network designed to
block unauthorized access while permitting outward communication.
