Cloud Architecture and Design
Question
When designing a three-node, load-balanced application, a systems administrator must ensure each node runs on a different physical server for HA purposes. Which of the following does the systems administrator need to configure?
Options
- ARound-robin methods
- BLive migration
- CAnti-affinity rule
- DPriority queues
Explanation
Anti-affinity rules enforce VM placement policies that keep specified VMs on separate physical hosts, ensuring high availability by preventing co-location on the same hardware.
Common mistakes.
- A. Round-robin is a load balancing algorithm that distributes incoming requests across nodes, not a mechanism for controlling physical server placement of VMs.
- B. Live migration moves a running VM from one host to another on demand but does not enforce an ongoing policy that keeps VMs separated across different physical servers.
- D. Priority queues are used in network traffic management or process scheduling to prioritize certain traffic or tasks, not to control VM-to-host placement.
