Question 6

An engineer has been given approval to upgrade their environment to the latest version of PAN-OS.
The environment consists of both physical and virtual firewalls, a virtual Panorama, and virtual log collectors.
What is the recommended order of operational steps when upgrading?

Correct Answer: C
When planning an upgrade in an environment that includes Panorama, firewalls, and log collectors, it's crucial to follow the recommended sequence to ensure compatibility and minimize disruptions. Palo Alto Networks recommends the following order:
Upgrade Panorama: Start with Panorama because it's the central management platform. Upgrading Panorama first ensures that it's compatible with the new PAN-OS versions that the managed devices (firewalls and log collectors) will be upgraded to. Panorama must be able to support the new versions for it to manage and monitor the devices effectively.
Upgrade the log collectors: Next, upgrade the log collectors. Since log collectors work closely with Panorama to aggregate and store logs from the firewalls, they should be upgraded after Panorama to ensure compatibility. Upgrading the log collectors ensures they can handle the log formats and features introduced in the new PAN-OS version.
Upgrade the firewalls: Finally, upgrade the firewalls. The firewalls are the last components to be upgraded to ensure that they remain compatible with the management and log collection infrastructure. Upgrading the firewalls last minimizes the risk of compatibility issues with Panorama and log collectors.
This sequence ensures that all components are compatible and that the management and logging infrastructure can fully support the firewalls running the latest PAN-OS version.

Question 7

An engineer reviews high availability (HA) settings to understand a recent HA failover event. Review the screenshot below.

Which timer determines the frequency at which the HA peers exchange messages in the form of an ICMP (ping)

Correct Answer: C
The heartbeat interval determines the frequency at which the HA peers exchange messages in the form of an ICMP (ping). The default value is 1000 milliseconds (1 second). The heartbeat interval is used to detect failures and trigger failover in an HA pair1. The other options are not correct. The hello interval determines the frequency at which the HA peers exchange messages in the form of an HA packet. The default value is 3000 milliseconds (3 seconds). The hello interval is used to establish and maintain HA connectivity2. The promotion hold time determines the amount of time that a passive firewall waits before it becomes active after detecting a failure on the active firewall. The default value is 5000 milliseconds (5 seconds)3. The monitor fail hold up time determines the amount of time that a firewall waits before it declares a monitor failure after detecting a link down event on an interface. The default value is 2000 milliseconds (2 seconds)4.

Question 10

The company's Panorama server (IP 10.10.10.5) is not able to manage a firewall that was recently deployed. The firewall's dedicated management port is being used to connect to the management network.
Which two commands may be used to troubleshoot this issue from the CLI of the new firewall?
(Choose two)

Correct Answer: B,D
B: The show panorama-status command shows the Panorama connection status.
Sample Output
The following command shows information about the Panorama connection.
username@hostname> show panorama-status
Panorama Server 1 : 10.1.7.90
State : Unknown
username@hostname>
D: Issue
The Managed Devices show not connected to Panorama and are not able to establish a new connection to Panorama.
The Packet Capture on Panorama Management Interface shows SYN packets received from devices on port 3978, but no SYN ACK is sent from Panorama.
> tcpdump filter "port 3978"
> view-pcap mgmt-pcap mgmt.pcap
