Based on growth trends, the team will ___ next quarter's traffic to size the infrastructure.
To forecast traffic means to project future demand from trends. Forecast is the precise term, behind "capacity forecast" and "demand forecasting." Guess up, predict out, and estimate over are informal or grammatically wrong. Teams "forecast traffic to plan capacity," so forecast traffic is the correct collocation.

The team will ___ enough headroom so the system can absorb sudden spikes.
To provision headroom means to allocate spare capacity beyond expected load. Provision is the precise term, behind "provisioned capacity." Set up out, buy over, and order up are informal. Engineers "provision headroom for spikes," so provision headroom is the correct collocation.

When CPU consistently exceeds 70 per cent, the system should ___ automatically.
To scale out means to add more instances to handle load (horizontal scaling). Scale out is the precise term, contrasted with "scale up" (bigger instances). Grow big, spread wide, and expand over are not real technical phrases. Engineers configure "auto-scaling to scale out under load," so scale out is the correct collocation.

During quiet periods, the cluster will ___ to reduce cost.
To scale in means to remove instances when demand drops (the opposite of scale out). Scale in is the precise term, behind "scale-in policy." Shrink down, pull back, and cut off are informal or imprecise. Engineers "scale in during off-peak hours," so scale in is the correct collocation.

The SRE will ___ a load test to determine the system's maximum sustainable throughput.
To run a load test means to execute a test that applies controlled load to measure capacity. Run is the standard term, behind "load testing" and tools like k6/JMeter. Do, play, and fire off are informal. Engineers "run a load test to find the ceiling," so run a load test is the correct collocation.
