Which port is used by default to communicate between VPN load-balancing ASAs?
Click on the arrows to vote for the correct answerA. B. C. D.
VPN load-balancing ASAs (Adaptive Security Appliances) are used to distribute VPN sessions among a group of VPN gateways or firewalls. These ASAs communicate with each other to share session information and ensure that sessions are balanced across the group.
The default port used by ASAs to communicate with each other for VPN load balancing is UDP port 9023. This port is used by the ASA control plane to exchange VPN session state information between ASAs.
Option A (TCP 9022) is not correct because the default protocol used by ASAs for VPN load balancing is UDP, not TCP.
Option B (UDP 9023) is correct because it is the default port used by ASAs to communicate for VPN load balancing.
Option C (TCP 9023) is not correct because the protocol used by ASAs for VPN load balancing is UDP, not TCP.
Option D (UDP 9022) is not correct because the correct port for VPN load balancing communication between ASAs is UDP 9023, not UDP 9022.
In summary, the correct answer is B - UDP 9023.
