Show Answer Hide Answer
Correct Answer: B

The IEEE 802.16 is a series of wireless broadband standards, also known as WirelessMAN, that are designed for Metropolitan Area Networks (MANs). This standard specifies the air interface, including the medium access control layer (MAC) and physical layer (PHY), of combined fixed and mobile point-to-multipoint broadband wireless access systems. It supports multiple services and enables the deployment of interoperable multivendor broadband wireless access products.


Question No. 4

Which Internet access policy starts with all services blocked and the administrator enables safe and necessary services individually, which provides maximum security and logs everything, such as system

and network activities?

Show Answer Hide Answer
Correct Answer: D

The Paranoid policy is an Internet access policy that begins with the premise that all services are blocked by default. Under this policy, the administrator must explicitly enable each service that is deemed safe and necessary. This approach ensures maximum security as it minimizes the potential attack surface by not allowing any services unless they have been vetted and approved. Additionally, this policy typically involves extensive logging of all system and network activities, which can be crucial for monitoring, auditing, and forensic purposes.


Question No. 5

Which encryption algorithm does S/MIME protocol implement for digital signatures in emails?

Show Answer Hide Answer
Correct Answer: A

S/MIME (Secure/Multipurpose Internet Mail Extensions) protocol implements the Rivest-Shamir-Adleman (RSA) encryption algorithm for digital signatures in emails. Digital signatures are a key component of S/MIME, providing authentication, message integrity, and non-repudiation. RSA is a widely used public-key cryptosystem that facilitates secure data transmission and is known for its role in digital signatures. It works on the principle of asymmetric cryptography, where a pair of keys is used: a public key, which is shared openly, and a private key, which is kept secret by the owner. In the context of S/MIME, the sender's email client uses the sender's private key to create a digital signature, and the recipient's email client uses the sender's public key to verify the signature.
