The Chief Information Security Officer (CISO) has mandated that all IT systems with credit card
data be segregated from the main corporate network to prevent unauthorized access and that
access to the IT systems should be logged. Which of the following would BEST meet the CISO’s
requirements?
A.
Sniffers
B.
NIDS
C.
Firewalls
D.
Web proxies
E.
Layer 2 switches
Explanation:
The basic purpose of a firewall is to isolate one network from another.
In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.[1] A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed not to be secure or trusted.

Layer 2 Switching has the ability to create VLAN(Virtual Local Area Networks). This in turn would segregate network traffic and accomplishing the CISO’s main objective. So with that the answer should be E.

“and that access to the IT systems should be logged” — may be this be a reason for answer “Firewall”?
