A recruiter at a large company is reviewing resumes, as they do
hundreds of times every day. Which of the following is the most
appropriate procedure for the recruiter to follow when deciding to
open a resume?
Question 5 options:
Only download resumes that were submitted to the online portal,
these would have been scanned by anti-virus software. These files
would be safe to open.
Download the resumes through whatever means they arrive (email or
app portal), but before opening the download, submit the file to
virustotal for anti-virus scanning. If it comes back clean, it's
safe to open.
Download resumes through a virtual machine that reverts to a former
state following a reboot. Reboot the machine after viewing each
resume.
Any of the above is appropriate.
None of the above is an appropriate procedure.
