Can you define SSL VPN and discuss how it differs from IPsec VPN?
Discussing different aspects of a VPN and comparing and contrasting them is another form of a technical question. These types of questions differentiate well-qualified candidates from individuals who are only familiar with the basic terms and processes used in this job. It is helpful if you know the company's operations and the type of protocols and processes they use to manage their network before the interview. This will help you to frame your answers, so they are relevant to the job the company is asking you to perform.
"SSL VPN is used to provide remote access from any internet-enabled device through a web browser, using its embedded SSL encryption. It does not require any special client software. When an IPsec VPN connection is initiated, it uses a VPN client software application and requires the prior installation of the special client software. IPsec is more secure than SSL, but it also requires more overhead and therefore is more cumbersome."
