HOTSPOT
Your network contains an Active Directory domain named contoso.com. All servers run
Windows Server 2012 R2. System Center 2012 R2 Virtual Machine Manager (VMM) is
deployed to the domain.
In VMM, you create a host group named HostGroup1. You add a 16-node Hyper-V failover
cluster to HostGroup1. From Windows PowerShell, you run the following commands:

Anyone care to explain this one ?
Well, after digging and reading around… I believe the answer is correct because:
EnablePowerOptimization is set to FALSE so the node will stay on no matter what (no matter if CPU, memory, or whatever is set). The node would power off if it was 5% because the CPUStartOptimzationLevel is set to 40% so if a node is below that number, it can be optimized.
The other value of MemoryStartOptimizationLevel is set to 4196 so that means “IF”, EnablePowerOptimization was set to TRUE, then it would shut down. But the question is asking you if the host would be considered for optimization under ANY circumstance or under what memory conditions.
I’m not 100% sure if I’m explaining this correctly but it is my interpretation. Here are some links to follow up on.

Jim appears to be correct.
From what I am reading from http://www.virtualizationadmin.com/articles-tutorials/microsoft-hyper-v-articles/management/deep-dive-scvmm-2012-r2-networking-and-storage-part3.html
Power Optimzation is required to be on in order too allow proper shutdown to save power. The command shows that “EnablePowerOptimziation” is false above.
Dynamic Optimization thresholds is an automatic mechanism and will start to optimize once it has hit the threshold. The threshold here is 4096 according to MemoryStartOptimzationLevel output.
It appears that Dynamic Optimization is always on, but can either inherit settings from it’s parent or not, but Power Optimization is required.
Answer: “Remain On” and “Only be considered for optimzation if memory is less than 4096”
I read it as “Remain On” and “Never be considered for optimization” same reasoning that the optimisation appears to be set to false.
