took the test last week, i did have about 15 - 20 word for word from this site on the test. (only was able to cram 600 of the questions from this site so maybe more were there i didnt review) had 4 labs, bgp, lacp, vrf with tunnels and actually had to skip a lab due to time. lots of automation syntax questions.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.
