1. Why is VM sprawl an issue?

• VM sprawl uses too many resources on parallel functions.
• The more virtual machines in use, the harder it is tomigrate a VM to a live server.
• Virtual machines are so easy to create, you end up with hundreds of small servers only performing a single function.
• When servers are no longer physical, it can be difficult to locate a specific machine.

2. What is masking?

1. The use of stand-in data to replace real-time data

2. The marking of regions where data is not allowed by policy

3. The use of backups to preserve data during disruptive events

4. Redacting portions of data using a covering symbol such as * or

x

3. What is a primary problem with biometrics?

• Technically, biometrics are difficult to implement
• The human body changes over time.
• Biometrics are easily faked.
• Biometrics can't be loaned or delegated.

4. How do you make a short secret, such as a password, become long enough for use?

• salting
• Key elongation
• Key stretching
• Ephemeral operations

5. What distinguishes high availability systems?

• The ability to change with respect to usage conditions
• The ability to process, even in times of disruption
• Automated backups and recovery functions
• The use of diversity to mitigate single threats
