The correct answer is B - Implementing security patches and updates on a regular basis and using hybrid cloud topology.
WGU Cybersecurity Architecture and Engineering (KFO1 / D488) emphasizes that timely application of security patches is critical to addressing vulnerabilities like outdated software. A hybrid cloud topology offers the flexibility and scalability needed by financial institutions while keeping sensitive data protected in more controlled environments.
Strong password policies (A) help, but public cloud alone may not be best for sensitive banking systems.
Antivirus (C) addresses only part of the threat. Private cloud (D) improves security but may not offer the scalability benefits of a hybrid approach.
