61. Which of the following network access methods is used to securely access resources, such as a corporate cloud or network, as if they were directly connected?
Answer: C
Client-to-site VPN is the method used to securely access resources as if directly connected.
A client-to-site VPN allows users to connect to a corporate network or cloud securely over the internet, creating a private connection that simulates being on the local network.
A) Jump box/host
A jump box, or jump host, is a system used to manage access to other machines in a network but does not inherently provide secure access to resources as if they were directly connected. While it can facilitate access, it does not create the same level of secure connection as a VPN.
B) Secure Shell
Secure Shell (SSH) is a protocol used for secure remote login to machines and secure file transfers. However, it is not a network access method that provides the equivalent of direct connection to a network or cloud resources, which is the core requirement of the question.
C) Client-to-site VPN
Client-to-site VPN is designed specifically for users to securely connect to a remote network as if they were physically present there. This method encrypts the connection, providing access to resources like corporate files and applications securely over the internet, making it the correct choice.
D) GRE tunnel
Generic Routing Encapsulation (GRE) tunnel is a tunneling protocol that encapsulates packets but does not provide encryption or secure access by itself. It is typically used for routing purposes rather than providing secure, direct network access, which makes it unsuitable for the question's context.
Conclusion
The client-to-site VPN is the definitive answer, as it provides a secure and direct means to access corporate networks and resources over the internet. Other options, while related to network access, do not meet the specific criteria of simulating a direct connection to resources.
