1Y0-312 Performance and Scalability Optimization Practice Question
An administrator is planning for a VDA rollout and needs to ensure that the user experience remains consistent during peak usage. What is the correct approach to setting up load management?
⚠ Common exam trap
Test-takers frequently rely on simple concurrent session counts rather than performance metrics, ignoring that real-world resource constraints dictate true load management.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Define custom Load Evaluators based on CPU, memory, and disk metrics.
Load management should be configured based on real-world constraints such as CPU, memory, and disk I/O, rather than just simple session counts. By setting Load Evaluators that monitor resource utilization, the Delivery Controller can intelligently distribute sessions to the least-burdened hosts. This prevents 'hot spots' in the cluster, ensuring that every user receives a consistent experience even when the overall environment is under heavy, sustained load.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure load balancing based solely on the number of sessions.
Why it's wrong here
Session-count-based balancing is naive and dangerous. Different users have vastly different resource demands. A host with 50 'idle' users might be less loaded than a host with 10 'power' users. Balancing solely by session count leads to uneven resource utilization and poor performance for users on high-demand hosts.
- ✓
Define custom Load Evaluators based on CPU, memory, and disk metrics.
Why this is correct
Custom Load Evaluators allow the environment to react to actual resource contention. By monitoring the most common bottlenecks, the Delivery Controller makes intelligent placement decisions. This ensures that sessions are always directed to the most capable hosts, maintaining performance consistency even during the most challenging periods of peak usage.
- ✗
Set all VDAs to have a maximum limit of 200 sessions.
Why it's wrong here
A hard limit of 200 sessions is often too high for typical server hardware, leading to severe resource exhaustion. Furthermore, a static limit does not account for the varying load that users place on the system, which means some hosts will be overwhelmed while others remain underutilized, hurting overall efficiency.
- ✗
Disable load balancing to allow users to connect to the first available host.
Why it's wrong here
Disabling load balancing causes all incoming requests to hit the same set of hosts, creating a bottleneck while leaving other hosts idle. This is a recipe for performance degradation and system instability. Effective load balancing is mandatory for any production environment to ensure that resources are utilized optimally and reliably.
