A company wants to separate VoIP phones from employee workstations while using the same physical switches. What technology should be implemented and why?

VLANs. They allow logical separation of devices on the same physical infrastructure, improving organization and security.

A security appliance loses power. The organization decides that users must still maintain connectivity even if some security protections are bypassed. Should the device be configured as fail-open or fail-closed? Explain.

Fail-open. This configuration prioritizes availability and allows traƯic to continue flowing despite the appliance failure.

An administrator needs secure command-line access to a Linux server over the Internet. Which protocol should be used and why?

SSH. It provides encrypted remote command-line access and supports secure authentication methods.

A public web server is being targeted by SQL injection attempts. Which security appliance would be most eƯective in stopping these attacks?

A Web Application Firewall (WAF), because it inspects HTTP traƯic and can identify and block application-layer attacks such as SQL injection
