PCNSA Device Management and Services Practice Question
Exhibit
admin@PA-500> show system info System info: Hostname: PA-500 Model: PA-500 - - - Time since last reboot: 120 days Free disk space: 70% Management IP: 192.168.1.1/24 Management gateway: 192.168.1.254 Management interface: ethernet1/0 DNS settings: - Primary: 8.8.8.8 - Secondary: 8.8.4.4
Refer to the exhibit. An administrator attempts to ping the firewall's management IP (192.168.1.1) from a host on the same subnet (192.168.1.0/24) but receives no response. What is the most likely cause?
⚠ Common exam trap
A common mix-up: candidates assume a firewall's management interface will respond to ping by default, similar to a router or switch, but Palo Alto Networks intentionally disables ICMP echo on the management interface to enforce least-privilege access.
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
✓
Ping is disabled on the management interface by default
By default, the management interface on a Palo Alto Networks firewall does not respond to ICMP echo requests (pings) unless the 'ping' service is explicitly enabled under the interface's management profile. This is a security measure to reduce the attack surface. The administrator must configure a management profile that permits ping and apply it to the management interface for ICMP responses to work.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The host is on a different VLAN than the management subnet
Why it's wrong here
The host is on the same subnet as per the stem.
- ✗
The management interface is down
Why it's wrong here
If down, the management IP would not show in system info.
- ✗
The firewall is in HA passive state
Why it's wrong here
Passive state still allows management access.
- ✓
Ping is disabled on the management interface by default
Why this is correct
ICMP echo replies are disabled by default for security.
