20
Q 
Jim has a critical server in the application tier of his cloud-based deployment.  He is looking at a device-specific security solution to add defense-in-depth capabilities to his currently deployed network-based security defenses.  He has been researching ways to mitigate potential hacking attempts.  What is a good solution for him?
A.  DMZ
B.  IDS
C.  IPS
D.  Classification automation
E.  HIDS
A

HIDS

A host intrusion detection system (HIDS) is a software that monitors the device on which it is installed to identify deviations from an established security policy.

21
Q 
A constantly changing six-digit numerical token is used in what type of cloud service?
A.  XML
B.  TLS
C.  SSL
D.  MFA
E.  JSON
A

MFA

Multifactor authentication (MFA) services use a token that is generated on a schedule and can be a numerical value. The other answers offered are not valid to the question.

22
Q 
Samantha has been asked to meet FedRamp compliance for her customer's new contract.  Where should she integrate compliance in her project?  (Choose four.)
A.  Hand-off
