A network administrator was to implement a solution that will allow authorized traffic, deny unauthorized traffic and ensure that appropriate ports are being used for
a number of TCP and UDP protocols. Which of the following network controls would meet these requirements?
A.
Stateful firewall
B.
Web security gateway
C.
URL filter
D.
proxy server
E.
web application firewall
Another typo:
“A network administrator …wants.. to implement a solution that will allow authorized traffic, deny unauthorized traffic and ensure that appropriate ports are being used for
a number of TCP and UDP protocols….
Which of the following network controls would meet these requirements?”
The question in here mentions traffic in the network. It does not say that it is “WEB” traffic.
So being the case that it is assumed that we are not talking about WEB Traffic, we can simply eliminate: B, C, D and E .
If then we add a definition: In computing, a stateful firewall is a network firewall that tracks the operating state and characteristics of network connections traversing it. The firewall is configured to distinguish legitimate packets for different types of connections.
Put all of the above together, it just leaves one possible answer: “A- Stateful firewall”
