QUESTION: 31

What is one of the advantages of using both symmetric and asymmetric cryptography in SSL/TLS?

Supporting both types of algorithms allows less-powerful devices such as mobile phones to use symmetric encryption instead.
Symmetric algorithms such as AES provide a failsafe when asymmetric methods fail.
Symmetric encryption allows the server to security transmit the session keys out-of-band.
Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

Answer(s): A

The change of a hard drive failure is once every three years. The cost to buy a new hard drive is $300. It will require 10 hours to restore the OS and software to the new hard disk. It will require a further 4 hours to restore the database from the last backup to the new hard disk. The recovery person earns $10/hour. Calculate the SLE, ARO, and ALE. Assume the EF = 1(100%). What is the closest approximate cost of this replacement and recovery operation per year?

$1320
$440
$100
$146

QUESTION: 34

Steve, a scientist who works in a governmental security agency, developed a technological solution to identify people based on walking patterns and implemented this approach to a physical control access.
A camera captures people walking and identifies the individuals using Steve’s approach.
After that, people must approximate their RFID badges. Both the identifications are required to open the door. In this case, we can say:

Although the approach has two phases, it actually implements just one authentication factor
The solution implements the two authentication factors: physical object and physical characteristic
The solution will have a high level of false positives
Biological motion cannot be used to identify people
