PCNSA Device Management and Services Practice Question

Which TWO are best practices for securing management access to a Palo Alto firewall? (Select two)

⚠ Common exam trap

Many exam-takers confuse 'disabling ping' (a minor, non-critical hardening step) with the core best practices of network segmentation and access control, leading them to select Option D instead of the more impactful Options C and E.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Use a dedicated management subnet

Using a dedicated management subnet (out-of-band management) isolates management traffic from production data traffic, reducing the attack surface and ensuring management access remains available even if the data plane is compromised. This is a foundational security best practice for any network device, including Palo Alto firewalls.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Use HTTPS with self-signed certificates

    Why it's wrong here

    Self-signed certificates can lead to man-in-the-middle; use trusted CA certificates.

  • Use SNMP v1 for monitoring

    Why it's wrong here

    SNMP v1 is insecure; use v3.

  • Use a dedicated management subnet

    Why this is correct

    Segregates management traffic from production.

  • Disable ping on the management interface

    Why it's wrong here

    Ping is useful for troubleshooting and not a security risk.

  • Restrict management access to specific IP addresses

    Why this is correct

    IP whitelisting reduces attack surface.
