    • SSH
    • SIP
    • S/MIME
    • SRTP
  7. A manager makes an unannounced visit to the marketing department and performs a walk-through of the office. The manager observes unclaimed documents on printers. A closer look at these documents reveals employee names, addresses, ages, birth dates, marital/dependent statuses, and favorite ice cream flavors.

Having reached a stalemate, which of the following is the MOST appropriate action to take NEXT?

    • Elevate to the Chief Executive Officer (CEO) for redress; change from the top down usually succeeds.
    • Find the privacy officer in the organization and let the officer act as the arbiter.
    • Notify employees whose names are on these files that their personal information is being compromised.
    • To maintain a working relationship with marketing, quietly record the incident in the risk register.
  8. A security administrator is implementing a secure method that allows developers to place files or objects onto a Linux server. Developers are required to log in using a username, password, and asymmetric key.

    Which of the following protocols should be implemented?

    • SSL/TLS
    • SFTP
    • SRTP
    • IPSec
  9. Which of the following BEST describes the purpose of authorization?

    • Authorization provides logging to a resource and comes after authentication.
    • Authorization provides authentication to a resource and comes after identification.
    • Authorization provides identification to a resource and comes after authentication.
    • Authorization provides permissions to a resource and comes after authentication.
  10. A security analyst is emailing PII in a spreadsheet file to an audit validator for after-actions related to a security assessment. The analyst must make sure the PII data is protected with the following minimum requirements:

    – Ensure confidentiality at rest.
    – Ensure the integrity of the original email message.

    Which of the following controls would ensure these data security requirements are carried out?

    • Encrypt and sign the email using S/MIME.
    • Encrypt the email and send it using TLS.
    • Hash the email using SHA-1.
    • Sign the email using MD5.
  11. The network information for a workstation is as follows:

    SY0-501 Part 37 Q11 103
    SY0-501 Part 37 Q11 103

    When the workstation’s user attempts to access www.example.com, the URL that actually opens is www.notexample.com. The user successfully connects to several other legitimate URLs. Which of the following have MOST likely occurred? (Choose two.)

    • ARP poisoning
    • Buffer overflow
    • DNS poisoning
    • Domain hijacking
    • IP spoofing
  12. Which of the following implements a stream cipher?

    • File-level encryption
    • IKEv2 exchange
    • SFTP data transfer
    • S/MIME encryption
  13. A security technician has been assigned data destruction duties. The hard drives that are being disposed of contain highly sensitive information. Which of the following data destruction techniques is MOST appropriate?

    • Degaussing
    • Purging
    • Wiping
    • Shredding
  14. Which of the following BEST explains how the use of configuration templates reduces organization risk?

    • It ensures consistency of configuration for initial system implementation.
    • It enables system rollback to a last known-good state if patches break functionality.
    • It facilitates fault tolerance since applications can be migrated across templates.
    • It improves vulnerability scanning efficiency across multiple systems.
  15. A Chief Information Security Officer (CISO) is performing a BIA for the organization in case of a natural disaster. Which of the following should be at the top of the CISO’s list?

    • Identify redundant and high-availability systems.

    • Secure cabinet
    • Faraday cage
    • Safe
  17. Which of the following is the MOST significant difference between intrusive and non-intrusive vulnerability scanning?

    • One uses credentials, but the other does not.
    • One has a higher potential for disrupting system operations.
    • One allows systems to activate firewall countermeasures.
    • One returns service banners, including running versions.
  18. While reviewing system logs, a security analyst notices that a large number of end users are changing their passwords four times on the day the passwords are set to expire. The analyst suspects they are cycling their passwords to circumvent current password controls. Which of the following would provide a technical control to prevent this activity from occurring?

    • Set password aging requirements.
    • Increase the password history from three to five.
    • Create an AUP that prohibits password reuse.

  19. A security analyst is running a credential-based vulnerability scanner on a Windows host.
