Question

Because the focus of ______ is to transport many different protocols, it has very limited security features. By contrast, IPSec has strong data confidentiality and data integrity features, but it can transport only IP traffic.

a. GRE
b. TLS
c. HTTP
d. UDP

Answer 1

GRE has limited security features and supports multiple protocols, while IPSec provides strong security but only for IP traffic.

Step-by-step explanation:

The protocol that is focused on transporting many different protocols but has very limited security features is GRE (Generic Routing Encapsulation). Contrasting this, IPSec (Internet Protocol Security) is designed with strong data confidentiality and data integrity features. However, IPSec is limited in that it can only transport IP traffic, which means it cannot be used to encapsulate protocols that do not operate over IP.
