The correct answers are A and D. Zombies and botnets are types of infections that allow malicious actors to remotely control infected computers and use them to launch distributed denial-of-service (DDoS) attacks against a target. A DDoS attack is a type of cyberattack that aims to overwhelm a server or a network with a large volume of traffic from multiple sources, causing it to slow down or crash.

A keylogger is a type of malware that records the keystrokes of a user and sends them to a remote server, often for the purpose of stealing passwords, credit card numbers, or other sensitive information.

Adware is a type of software that displays unwanted advertisements on a user’s computer, often in the form of pop-ups, banners, or redirects. Adware can also collect user data and compromise the security and performance of the system.

Ransomware is a type of malware that encrypts the files or locks the screen of a user’s computer and demands a ransom for their restoration. Ransomware can also threaten to delete or expose the user’s data if the ransom is not paid.

Incremental backups are backups that only include the changes made since the last backup, whether it was a full or an incremental backup. Incremental backups minimize the capacity of storage used and are often used in conjunction with synthetic full backups, which are backups that combine a full backup and subsequent incremental backups into a single backup set.

A soft token, also known as a software token or an OTP (one-time password) app, is a type of multifactor authentication that generates a temporary code or password on a user’s device, such as a smartphone or a tablet. The user must enter this code or password along with their username and password to access their account or service. A soft token can help improve security by adding an extra layer of verification and preventing unauthorized access even if the user’s credentials are compromised. A soft token can also be implemented at a minimal cost, as it does not require any additional hardware or infrastructure. Biometrics, access control lists, and smart card are not types of multifactor authentication that can be implemented at a minimal cost.

RDP (Remote Desktop Protocol) is a protocol that allows a user to connect to and control a remote computer over a network. RDP can be used to perform Windows updates on a department’s servers without physically accessing them.
