Vivian is investigating a website outage that brought down her company's ecommerce platform for several hours.  During her investigation, she noticed that the logs are full of millions of connection attempts from systems around the world, but those attempts were never completed.  What type of attack likely took place? A. DoS B. Cross-site request forgery C. Cross-site scripting D. DDoS Correct Answer: D This is a clear example of a distributed denial of service (DDoS) attack. The half-open connections indicate the use of a denial of service attack. The fact that the requests came from all over the world makes it clear that it is more than a standard denial of service attack. There is no indication that there was a web application flaw, such as cross-site request forgery or cross-site scripting. Interested in more practice test questions?

K1=K2, K2 is not equal to K3 B. K1, K2, and K3 are independent C. K2=K3, K1 is not equal to K3 D. K1=K2=K3 Correct Answer: B The most secure implementation of 3DES uses three independent keys. This approach creates a key with 168 (56x3) independent bits. When all three keys are the same, the key length is only 56 bits. When only two keys are independent, the key length is 112 bits.
