- (i) Firewall can screen traffic going into or out of an organization.
- (ii) Virtual private networks cam simulate an old leased network to provide certain desirable properties.
Choose the correct answer from the code given below:
(A) (i) only
(B) Neither (i) nor (ii)
(C) Both (i) and (ii)
(D) (ii) only
Explanation: A firewall is a network security device, either hardware or software-based, which monitors all incoming and outgoing traffic and based on a defined set of security rules it accepts, rejects or drops that specific traffic. So, statement (i) is correct.
