Which component does Stargate depend on to gather metadata and Zeus to gather cluster configuration data?
Stargate is a critical component in the Nutanix architecture responsible for handling storage operations. Medusa, an internal module, is utilized by Stargate to collect metadata. Simultaneously, Zeus is employed to obtain cluster configuration information. Hence, the correct answer is Medusa.

this is the right answer. In the link on the stargate entry it specify the answer of this question. This question can easily misunderstood.
Correct answer: C https://next.nutanix.com/how-it-works-22/controller-vm-components-38055#:~:text=Stargate%20depends%20on%20Medusa%20to,to%20gather%20cluster%20configuration%20data.&text=Stargate%20is%20responsible%20for%20all,%2C%20iSCSI%2C%20or%20SMB).

The correct answer is A. Nutanix's implementation of Cassandra uses a version of Apache Cassandra that has been modified for high performance and automatic, on-demand scaling. Cassandra stores all metadata about the guest VM data in a Nutanix storage container. Cassandra runs on all nodes of the cluster. These nodes communicate with each other once a second using the Gossip protocol, ensuring that the state of the database is current on all nodes. Cassandra depends on Zeus to gather information about the cluster configuration.
I realized that I was wrong on this one. The correct answer is Medusa. This comes from the ECA e-learning module. Stargate A distributed system that presents storage to other systems (such as a hypervisor) needs a unified component for receiving and processing data that it receives. The Nutanix cluster has a software component called Stargate that manages this responsibility. All read and write requests are sent across an internal vSwitch to the Stargate process running on that node. Stargate depends on Medusa to gather metadata and Zeus to gather cluster configuration data. From the perspective of the hypervisor, Stargate is the main point of contact for the Nutanix cluster.
This is incorrect. Medusa is the interface that Stargate uses to collect metadata from Cassandra. Cassandra then uses Zues to collect cluster config. Answer is B.
Correction: A.
