Add more interfaces to the router that is connected to the internal network.

5 What is an advantage of using a deterministic IP addressing scheme?

easy path determination for routers
knowing each user device IP address
controlling access to devices by IP address*
avoiding traffic congestion

6 Which type of malware will disguise itself as a legitimate program and execute its malicious code once the program is run?

Trojan*
virus
worm
spyware

7 Place the recommended steps for worm attack mitigation in the correct order. (Not all options are used.)
