Question 277
How does vSphere HA handle the “Isolation Response” setting when an ESXi host loses all management network connectivity?
- It executes a predefined action (such as leaving VMs powered on or powering them off) to prevent split-brain scenarios or data corruption.
- It prints paper error reports on office network printers.
- It increases physical CPU clock speeds on demand.
- It deletes all virtual machine configuration files permanently.
Correct Answer: 1
Explanation
The vSphere HA isolation response dictates what happens to virtual machines running on an ESXi host that has lost network connectivity to the rest of the cluster. Administrators can configure the host to leave virtual machines running, power them off, or shut them down gracefully, depending on application availability requirements.
Question 278
What is the operational difference between stateless and stateful firewall rules in the NSX Distributed Firewall?
- Stateless rules inspect individual packet headers in isolation, while stateful rules track connection states (such as TCP handshakes) to permit return traffic automatically.
- Stateless rules require physical router cables, while stateful rules run entirely on paper.
- Stateless rules delete virtual machines daily.
- Stateless rules encrypt all disk files.
Correct Answer: 1
Explanation
Stateless firewall rules evaluate each packet independently based purely on source, destination, and port parameters without tracking session history. Stateful firewall rules maintain connection state tables, meaning an outbound permitted connection automatically tracks and allows legitimate return traffic without requiring explicit bidirectional rule entries.
