A new host with two quad-core processors and 128 GB RAM will host ten guest servers requiring 1 CPU and 8 GB RAM each, with four off-hours. Which feature should be implemented to ensure proper resources?

A new host with two quad-core processors and 128 GB RAM will host ten guest servers requiring 1 CPU and 8 GB RAM each, with four off-hours. Which feature should be implemented to ensure proper resources?

• A. Dynamic CPU
• B. Redundancy
• C. NIC Teaming
• D. Dynamic RAM

Answer: (A)

Dynamic CPU scheduling is what you want here. The host has 8 physical CPU cores but ten virtual machines each needing a CPU, so there will be contention if all are active at once. Because four hours are off, the workload isn’t constant, and the hypervisor can reuse CPU cycles where needed. Dynamic CPU lets the hypervisor allocate CPU time to VMs based on demand, time-slice resources, and reclaim idle cycles, helping prevent CPU bottlenecks as workloads vary. RAM isn’t the bottleneck since 10 × 8 GB = 80 GB total, well under the 128 GB available, so adjusting memory isn’t necessary in this scenario. Redundancy deals with uptime, NIC teaming with network throughput or resilience, and Dynamic RAM would address memory pressure—none are as directly relevant as dynamically scheduling CPU resources for this fluctuating workload.
