Networks, Linux and Systems: The Technical Foundations of Cybersecurity Quiz

Quiz: Building your laboratory

Pass mark: 70%. You can retry as many times as you need.

1 Which virtual network mode is the most dangerous for a machine that is intentionally vulnerable, and why? Single answer Internal network, because the VMs can reach each other. Bridged, because the VM becomes a reachable device on your real network. Host-only, because the host can reach the VM. NAT, because it has no DHCP server.

2 Which actions are good practice when downloading and installing a lab image? (several answers) Multiple answers possible Download from the official website of the project. Take a convenient pre-modified image from an unknown forum. Compare the checksum with the one published by the project. Change any default password at the first login.

3 What is the difference between a snapshot and a backup? Single answer A snapshot is stored with the VM and does not protect against losing the VM's storage; a backup is an independent copy. There is no difference. A backup can only be restored on the same day. A snapshot is stored in the cloud automatically.

4 In your isolated lab, Kali has the address 10.10.10.10/24 and the server 10.10.10.20/24. You mistakenly type a command that targets 192.168.1.1 from Kali with only the internal adapter enabled. What is the most likely result, and what does it show? Single answer It reaches the real gateway through NAT, because Kali is the attacker machine. It reaches the gateway, because all /24 networks are connected. It is automatically redirected to 10.10.10.20. It fails, because the lab has no route out of its network, which shows that the isolation is working.

5 Which statements about the legal framework are correct? (several answers) Multiple answers possible Fraudulent access to a system can be an offence even if nothing is stolen or damaged. Good intentions make an unauthorised test legal. Written authorisation and a defined scope distinguish a professional test from an offence. Practising only on your own lab and legal training platforms is the safe way to learn.
