It is easy for the attacker to intercept VoIP calls. True or false?
a. True
b. False
b. False
Explanation: It actually takes someone who is technically sophisticated to intercept VoIP telephone calls. VoIP systems have two possible types of vulnerabilities. The first is the level of network security running the VoIP data traffic. Threats of intrusion and denial-of-service for VoIP networks are the same that exist in a traditional data network. A well-protected infrastructure can help to better secure the network.

Develop a decision tree for the True Disk company discount policy in Problem below.
A computer supplies firm called True Disk has set up accounts for countless businesses in Dosville. True Disk sends out invoices monthly and will give discounts if payments are made within 10 days. The discounting policy is as follows: If the amount of the order for computer supplies is greater than $1,000, subtract 4 percent for the order; if the amount is between $500 and $1,000, subtract a 2 percent discount; if the amount is less than $500, do not apply any discount. All orders made via the Web automatically receive an extra 5 percent discount. Any special order (computer furniture, for example) is exempt from all discounting.
