質問 # 14
Refer to the Exhibit:
An administrator needs to create two virtual machines: VM4 and VM5 that leverage the memory over-commit feature.
Once VM4 is created and running, the administrator notices that it uses only 28GB of RAM.
What will be the maximum RAM that can be allocated to VM5 so that it can be powered on?
- A. 16GB
- B. 32GB
- C. 8GB
- D. 4GB
正解：C
解説：
Understanding the Exhibit & Memory Allocation
* Thehost has 128GB of physical RAM.
* Thecurrent memory allocationacrossthree VMs (VM1, VM2, VM3) is 128GB, but only92GB is actually utilized.
* This means there is36GB of unutilized memory available for allocation.
Step-by-Step Breakdown
* Existing Memory Usage Before Adding VM4
* Total Physical RAM:128GB
* Used by running VMs (VM1, VM2, VM3):92GB
* Unutilized Memory Available:36GB
* After Creating and Running VM4
* VM4 is allocatedmemory but only utilizes 28GB.
* The table does not show VM4's allocated RAM, but assuming it was given a reasonable allocation, it must have been taken from the36GB unutilized memory pool.
* IfVM4 uses 28GB, theremaining unutilized memory is now (36GB - 28GB) = 8GB.
* Maximum Memory Allocation for VM5
* Sinceonly 8GB remains unutilized, the maximum memory VM5 can be allocated while still allowing it to power on is8GB.
Evaluating the Answer Choices
* (A) 4GB#(Incorrect)
* More memory (8GB) is available, so limiting to 4GB is unnecessary.
* (B) 8GB#(Correct)
* Theremaining unutilized memory after VM4 is 8GB, so VM5 can be allocated up to8GBwhile ensuring it can power on.
* (C) 16GB#(Incorrect)
* Only8GB is left, so 16GB isnot possible.
* (D) 32GB#(Incorrect)
* There isnot enough unutilized memoryto allocate 32GB.
Key Concept: Nutanix Memory Overcommit
* Nutanix AHV supportsmemory overcommit, meaning VMs can be allocated more memory than physically available usingmemory ballooning and swapping.
* However,to power on VM5 without impacting performance, it must fit within the available unutilized memory, which is8GB.
質問 # 15
An administrator noticeshigh CPU usage on a VMand wants to determine whether addingmore vCPUs would improve performance.
Which two metrics should be analyzed to make this decision? (Choose two.)
- A. VM CPU Usage
- B. Host CPU Usage
- C. VM CPU Ready Time
- D. Host Memory Swap Out Rate
正解：A、C
解説：
When diagnosing CPU performance issues, CPU Ready Time and CPU Usage are the key indicators of whether more vCPUs are needed.
* Option A (VM CPU Ready Time) is correct:
* High CPU Ready Time means the VM is waiting for CPU resources, indicatingCPU contention.
* Option B (VM CPU Usage) is correct:
* If CPU usage isconsistently high, adding more vCPUsmay improve performance.
* Option C (Host CPU Usage) is incorrect:
* Host-wide CPU usage does not indicate whether a specific VM needs more vCPUs.
* Option D (Host Memory Swap Out Rate) is incorrect:
* Memory swappingaffects RAM performance, not CPU allocation.
References:
* Nutanix Prism Central Guide#Analyzing VM CPU Performance
* Nutanix KB#Understanding CPU Ready Time and VM Performance
質問 # 16
An administrator receives complaints about VM performance.
After reviewing theVM's CPU Ready Timedata shown in the exhibit, which step should the administrator take to diagnose the issue further?
- A. Assess cluster SSD capacity.
- B. Review host CPU utilization.
- C. Check the number of vCPUs assigned to each CVM.
- D. Enable VM memory oversubscription.
正解：B
解説：
Understanding the Issue
The administrator is investigating VM performance complaints and is analyzing CPU Ready Time data.
* CPU Ready Time is a crucial metric in Nutanix and virtualization environments (AHV, ESXi, or Hyper-V).
* It measures the amount of time a VM is waiting for CPU scheduling due to resource contention.
* High CPU Ready Time indicates that VMs are ready to run but are waiting because the host lacks available CPU resources.
Analysis of the Exhibit
* The graph shows CPU Ready Time spikes for multiple VMs.
* Some VMs have CPU Ready Time exceeding 18% to 21.5%, which is very high.
* A healthy CPU Ready Time should be below 5%.
* Values above 10% indicate CPU contention, and anything above 20% is critical and requires immediate troubleshooting.
Evaluating the Answer Choices
#(A) Check the number of vCPUs assigned to each CVM. (Incorrect)
* CVMs (Controller VMs) have fixed CPU allocation, and modifying their vCPU count is not recommended unless advised by Nutanix Support.
* The issue is related to VM CPU contention, not CVM configuration.
#(B) Review host CPU utilization. (Correct Answer)
* High CPU Ready Time suggests CPU overcommitment or host saturation.
* The administrator should check host CPU usage in Prism Central to determine if the cluster is overloaded.
* If host CPU usage is consistently above 85-90%, VMs are competing for CPU resources, leading to high CPU Ready Time.
#(C) Assess cluster SSD capacity. (Incorrect)
* SSD capacity impacts storage performance (latency, read/write speeds) but does not affect CPU Ready Time.
* High CPU Ready Time is a CPU scheduling issue, not a storage bottleneck.
#(D) Enable VM memory oversubscription. (Incorrect)
* Memory oversubscription does not impact CPU scheduling.
* Enabling memory oversubscription affects RAM allocation, but CPU Ready Time is strictly related to CPU contention.
Next Steps to Diagnose & Resolve the Issue
* Review Host CPU Utilization:
* Navigate to Prism Central # Analysis # CPU Usage per Host.
* Identify hosts experiencing high CPU load.
* Check VM vCPU Allocation:
* Ensure that VMs do not have excessive vCPUs assigned, which can lead to scheduling inefficiencies.
* Overprovisioning vCPUs can cause unnecessary contention.
* Balance Workload Across Hosts:
* Use Nutanix AHV DRS (Dynamic Scheduling) or VMware DRS to redistribute VMs across hosts.
* Check if certain hosts are overloaded while others have spare CPU capacity.
* Consider Scaling Out the Cluster:
* If CPU usage is consistently high, adding more nodes may be required to reduce CPU contention.
Multicloud Infrastructure References & Best Practices
* CPU Ready Time Best Practices:
* Keep CPU Ready Time below 5%.
* Avoid overcommitting vCPUs on heavily loaded hosts.
* Monitor Prism Central Runway Metrics to predict future CPU resource needs.
* Nutanix AHV CPU Scheduling Optimization:
* Ensure proper VM sizing (avoid excessive vCPU allocation).
* Balance workloads using Nutanix AHV DRS.

質問 # 17
Refer to Exhibit:
After adding new workloads, why isOverall Runway below 365 daysandthe scenario still shows the cluster is in good shape?
- A. Because there are recommended resources.
- B. Because the Target is 1 month.
- C. Because new workloads are sustainable.
- D. Because Storage Runway is still good.
正解：C
解説：
InNutanix Capacity Planning,Overall Runwayrepresents how long the cluster can support current and new workloads before resources are exhausted.
* Even if the runway is below 365 days, the system considers the cluster to be in good shape if new workloads are sustainable (Option B).
* Option A is incorrect: Storage runway alone is not the only factor; CPU and memory are equally important.
* Option C is incorrect: The presence of recommended resources does not mean the cluster is in good shape.
* Option D is incorrect: The target of 1 month affects projections but does not explain why the cluster is in good shape.

質問 # 18
Due toapplication requirements, an administrator needs to support amulticast configurationin anAHV cluster.
Which AHV feature can be used to optimize network traffic so that multicast traffic is only forwarded to the VMs that need to receive it?
- A. UDP
- B. IGMP Snooping
- C. Network Segmentation
- D. LACP
正解：B
解説：
Multicast traffic can generate unnecessary overhead if it is not properly managed.IGMP Snooping (Option C)ensures thatmulticast packets are only sent to VMs that have requested them, rather than broadcasting to all VMs.
* Option C (IGMP Snooping) is correct:
* Itreduces unnecessary multicast trafficby ensuring that only subscribed VMs receive the packets.
* It is supportednatively in AHV networking.
* Option A (LACP) is incorrect:
* Link Aggregation Control Protocol (LACP)improves bandwidth and redundancy but doesnot control multicast traffic.
* Option B (UDP) is incorrect:
* UDP (User Datagram Protocol) is a transport protocol, not a network optimization feature.
* Option D (Network Segmentation) is incorrect:
* Segmentation (VLANs, VPCs) isolates networksbut does not optimizemulticast traffic specifically.
