Cybersecurity Essentials Module 3 Quiz Answers
Module 3: System and Network Defense Quiz Question Answers
1. You are setting up a wireless network. What technology should you set up on the network to prevent man-in-the-middle attacks?
- Mutual authentication
- Biometric authentication
2. What type of lock is recommended to secure an office door?
- Cipher lock
- Keyed entry lock
- Security cage
- Cable lock
Explanation: A cipher lock uses buttons that are pressed in a given sequence to open the door. It can be programmed so that a user’s code may only work during certain days or times. It can also keep a record of when the door opened, and the code used to open it.
3. What can you do to ensure that network operating software remains secure? (Choose three.)
- Install patches and updates regularly
- Implement data classification standards
- Conduct software testing prior to launch
- Develop a policy to address application software and operating system updates
Explanation: To secure operating systems against threats, policies that address application system and operating system updates should be implemented so that patches and operating system updates are installed regularly.
4. What is a demilitarized zone (DMZ)?
- A small network between two trusted private networks
- A small network between a trusted private network and the Internet
- A demilitarized zone (DMZ) is a small network between a trusted private network and the Internet.
5. Which type of technology can prevent malicious software from displaying unwanted popup ads on a device?
- Spyware protection
- Antivirus protection
- Adware protection
Explanation: Adware protection is software that can can be installed on a computer system to prevent popup ads from displaying.
6. What would you set up to divide a computer network into smaller parts with the aim of improving network performance and security?
- A DMZ
- A VLAN
- A LAN
7. Which of the following enables secure contactless payment?
- USB communication
- Infrared (IR)
- Near-field communication (NFC)
Explanation: Near-field communication (NFC) allows contactless communication between devices. NFC chips use electromagnetic fields to enable contactless payments, meaning, for instance, that you simply need to hold your device close to a payment terminal to process payment.
8. What feature does Microsoft Windows use for full disk encryption (FDE)?
- Trusted Platform Module (TPM)
- BitLocker To Go
- Measured Boot
- BitLocker
Explanation: The Windows Encrypting File System (EFS) feature allows users to encrypt files, folders or an entire hard drive. Full disk encryption (FDE) encrypts the entire contents of a drive (including temporary files and memory). Microsoft Windows uses BitLocker for FDE.

- Code signing
- Secure cookies
- Validation rules
- A checksum
10. You want to keep unauthorized users and devices out of a private network. What solution would you use?
- Network Access Control (NAC)
- NetFlow
Explanation: Network Access Control (NAC) is a networking solution that protects a private network from unauthorized users and devices. NAC only allows authorized users with security-compliant systems to access the network. For example, a laptop that is part of a home wireless network may not be allowed to connect remotely to the office network.
11. What technique can a developer use to prevent software from being reverse engineered by a hacker?
- Stored procedure
- Code reuse
- Obfuscation
- Normalization
