CVSS (Common Vulnerability Scoring System) is a framework and a metric that provides a standardized and consistent way of assessing and communicating the severity levels of vulnerabilities. It assigns a numerical score and a vector string to each vulnerability based on various factors, such as exploitability, impact, scope, etc. It can help communicate to the leadership team the severity levels of the organization's vulnerabilities by providing a quantitative and qualitative measure of the risks and the potential impacts.

Based on CompTIA SY0-601 Security+ guide, the answer to the question is A. Identify rogue access points.
To secure the wireless perimeter of its physical facilities, the corporate security team should focus on identifying rogue access points, which are unauthorized access points that have been set up by employees or outsiders to bypass security controls.

SSH stands for Secure Shell Protocol, which is a cryptographic network protocol that allows secure remote login and command execution on a network device12. SSH can encrypt both the authentication information and the data being exchanged between the client and the server2. SSH can be used to access and manage a NAS device remotely3.

A Web Application Firewall (WAF) is a security solution that protects web applications from various types of attacks such as SQL injection, cross-site scripting (XSS), and others. It is typically deployed in front of web servers to inspect incoming traffic and filter out malicious requests.
To protect the company's website from malicious web requests over SSL, a decryption certificate is needed to decrypt the SSL traffic before it reaches the WAF. This allows the WAF to inspect the traffic and filter out malicious requests.

Retina authentication is the most accurate biometric authentication method. Retina authentication is based on recognizing the unique pattern of blood vessels and other features in the retina. This makes it virtually impossible to duplicate or bypass, making it the most secure form of biometric authentication currently available.
