What are two minimum prerequisites for live migration to succeed? (Choose two.)
What are two minimum prerequisites for live migration to succeed? (Choose two.)
To successfully perform a live migration, it is essential that all AHV hosts have IP addresses in the same subnet and are configured on the same VLAN. The migration process occurs at the hypervisor level, and thus, it relies on the management and network configuration of the hosts rather than the VM networks or IP addresses. The configuration involves ensuring that hypervisors can communicate effectively, which requires them to be in the same subnet and VLAN.
How should an administrator enable secure access to Volumes using a password?
To enable secure access to Volumes using a password, the administrator should use CHAP (Challenge-Handshake Authentication Protocol). CHAP provides a method for secure password-based authentication, ensuring that the communication between the client and the volume is authenticated and protected against unauthorized access.
An administrator is working on a one-node ROBO cluster configuration.
Which statement is true for this configuration?
The one-node ROBO cluster configuration specifically supports certain hardware models, such as NX-1175S-G5 and NX-1175S-G6, as these are designed to meet the requirements and optimizations for a single-node setup. This configuration ensures compatibility and efficient deployment in remote and branch office environments.
An administrator receives an alert email that indicates that a health check has failed.
Which action should the administrator take to collect more information on the failed check?
Re-running the check from the CVM CLI using the ncc command will provide comprehensive and detailed information about the failed health check. This approach allows the administrator to view real-time data and error messages that can help in diagnosing the issue more effectively.
A cluster has RF2. The cluster loses two drives on different nodes in the same storage tier.
What is the effect on the replicas of the VMs?
In a cluster with RF2 (Replication Factor 2), the system is designed to tolerate the failure of one component (e.g., a drive or node) without data loss. If a second drive fails on a different node before the cluster has had time to rebuild (heal) the lost data, there is a risk of data loss. Therefore, some VM data may be lost in the described scenario.
