Question 524
Correct Answer: A
The timer that determines the frequency between packets sent to verify that the HA functionality on the other HA firewall is operational is the Hello Interval. According to the documentation, the Hello Interval is the interval in milliseconds between hello packets that are sent to ensure the HA functionality of the other firewall is operational. This is different from the Heartbeat Interval, which is used primarily for connectivity verification through ICMP pings. Therefore, the correct option is Hello Interval.

villinOption: A
basically, heartbeat is for connectivity and hello is for functionality

A, please check this https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/high-availability/ha-concepts/ha-timers
mercysayno765Option: A
A. Hello Interval (ms) Interval in milliseconds between hello packets that are sent to verify that the HA functionality on the other firewall is operational. The range is 8000-60000 ms with a default of 8000 ms for all platforms. https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/high-availability/ha-concepts/ha-timers
MetgatzOption: A
The hello interval es the interchange of HA information hello packets. Heartbeat Interval a a ICMP/Ping test.
B_B_19Option: A
Hello Interval - interval in milliseconds between hello packets that are sent to verify that the HA functionality on the other firewall is operational (range is 8,000 to 60,000; default is 8,000). from the 11.0 guide: https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-admin/high-availability/ha-concepts/ha-timers#idcc1faa1c-5cd8-4830-90da-93e8effab23d

Why are there so many wrong solutions given as the correct answer?
MarshpillowzOption: A
A is correct
Andromeda1800Option: A
A is correct.
Andromeda1800Option: A
It's A. It is visible clear in the shared links.
dorf05Option: C
I will go for C.... because of the key "on the other HA firewall". While Hello is to each other.
sov4Option: A
A. Keepalive is a ping. Heartbeat is a message sent to the other firewall to see if it's still functioning.
PaloSteveOption: C
https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/high-availability/ha-concepts/failover "Heartbeat Polling and Hello messages- The firewalls use hello message and heartbeats to verify that the peer firewall is responsive and operational. Hello messages are sent from one peer to the other at the configured Hello Interval to verify the state of the firewall. The heartbeat is an ICMP ping to the HA peer over the control link, and the peer responds to the ping to establish that the firewalls are connected and responsive. By default, the interval for the heartbeat is 1000 milliseconds. A ping is sent every 1000 milliseconds and if there are three consecutive heartbeat losses, a failovers occurs. For details on the HA timers that trigger a failover, see HA Timers." Since the failover here talks about pings, and Heartbeat is the one that does pings, I'm leaning towards Answer C.
