Which statement is true about the requirements for ACOS devices that are part of an aVCS cluster?
Click on the arrows to vote for the correct answer
A. B. C.C
The correct answer is C. Devices in an aVCS (active Virtual Chassis System) cluster must be the same model and have the same optional hardware cards.
aVCS is a technology offered by A10 Networks that allows multiple ACOS devices to be clustered together and managed as a single logical unit. Clustering provides high availability, load balancing, and scale-out capabilities to the network. When configuring an aVCS cluster, it is essential to ensure that all devices have the same hardware specifications to ensure optimal performance and avoid issues that could arise from hardware mismatches.
Option A is incorrect because not all Thunder series devices are compatible with each other in aVCS clustering. Thunder series devices must meet specific requirements to be part of an aVCS set, and not all devices are compatible with each other.
Option B is also incorrect because while devices must be the same model, they cannot have different optional hardware cards. A10 Networks recommends that devices within an aVCS cluster have the same hardware specifications, including optional hardware cards, to ensure that there are no performance discrepancies between devices.
Therefore, the correct answer is C - Devices must be the same model and have the same optional hardware cards.
