How aVCS Changes on the vMaster are Pushed to vBlades

C

In A10 Networks' terminology, aVCS refers to the aVCS (Advanced Core Operating System) feature, which is a virtual chassis system that allows multiple A10 Thunder devices to be managed as a single logical entity. The aVCS consists of a virtual master (vMaster) and multiple virtual blades (vBlades). The vMaster is responsible for managing the configuration and synchronizing changes across all the vBlades within the aVCS.

Now, let's analyze each answer choice and determine the correct one:

A. HA Sync needs to be done: High Availability (HA) Sync refers to the process of synchronizing the configuration between a pair of active-standby devices. While HA Sync is necessary for maintaining configuration consistency between the active and standby devices, it is not directly related to pushing aVCS changes from the vMaster to the vBlades. Therefore, this answer choice is not correct in the context of the given question.

B. VRRP-A should be failed over: VRRP-A (Virtual Router Redundancy Protocol-A) is a protocol used for providing default gateway redundancy in a network. However, it does not directly relate to pushing aVCS changes from the vMaster to the vBlades. Therefore, this answer choice is also not correct.

C. Automatically: This answer choice suggests that aVCS changes performed on the vMaster are automatically pushed to the vBlades. In the aVCS architecture, the vMaster is designed to automatically synchronize configuration changes across all the vBlades. Whenever a configuration change is made on the vMaster, it will propagate the changes to the vBlades without requiring any manual intervention. Therefore, this answer choice is the correct one.

D. aVCS reload has to be performed: Performing an aVCS reload is not a requirement for pushing aVCS changes from the vMaster to the vBlades. While an aVCS reload may be necessary in certain cases, such as when adding or removing vBlades from the aVCS, it is not directly related to the regular process of pushing configuration changes. Therefore, this answer choice is not correct for the given question.

To summarize, the correct answer is: C. Automatically When aVCS changes are performed on the vMaster, they are automatically pushed to the vBlades within the aVCS without requiring any additional manual steps.
