A programming language is a formal language comprising a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms and manipulate data. They provide the vocabulary and grammatical rules for instructing a computer to perform specific tasks, allowing developers to write software programs that can be executed by a computer.

The correct answer is B — Internet Protocol Security (IPsec).

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), IPsec provides secure communication over IP networks by encrypting and authenticating IP packets. It is widely used for site-to-site VPNs and ensures confidentiality, integrity, and authentication between different cloud environments like Azure and AWS.

TCP (A) is a transport layer protocol ensuring reliable delivery but not encryption. FTP (C) is used for file transfer and is insecure unless secured with extensions. SSH (D) secures remote terminal sessions but is not primarily used for network-wide secure communication.

Reference Extract from Study Guide:

"IPsec provides a secure method of communication across IP networks, ensuring data confidentiality, integrity, and authentication for VPN connections and hybrid cloud communications."

=============================================

The correct answer is B — Sixteen characters with at least one letter, one number, and one symbol.

According to the WGU Cybersecurity Architecture and Engineering (KFO1 / D488) Study Guide, strong password policies must enforce a minimum length (preferably 12 to 16 characters) and require complexity, including uppercase and lowercase letters, numbers, and special characters. Sixteen-character passwords that include varied character types greatly increase the difficulty for attackers using brute-force or dictionary attacks.

Options A, C, and D either lack complexity or have too few characters, making them vulnerable to attacks.

Reference Extract from Study Guide:

"A strong password should be at least 12–16 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special characters to maximize resistance to brute-force attacks."

The correct answer is B — Regularly backing up the data stored in the POS system and having a disaster recovery plan can help ensure that the system is available in the event of a security incident or system failure.

As explained in WGU Cybersecurity Architecture and Engineering (KFO1 / D488), backing up critical systems and establishing a disaster recovery plan ensures business continuity and system availability even after incidents like hardware failures, cyberattacks, or data corruption.

While intrusion detection (A), access control (C), and patch management (D) contribute to overall security, backups and disaster recovery specifically ensure availability.

Reference Extract from Study Guide:

"Data backups and disaster recovery planning are essential controls to ensure system availability during and after a security incident or technical failure."
