Cloud+ Capacity Planning & Right-Sizing Quiz

1. Auto-scaling policies should be based on which parameters?

CPU, memory, network metrics, and custom application metrics

Administrator mood and time of day

Only the number of users logged in

Random selection of thresholds

2. Which factor most influences whether to scale horizontally versus vertically?

Application architecture, bottleneck type, and fault tolerance requirements

Cloud provider marketing materials

The administrator's personal preference

The current day of the week

3. What is the benefit of implementing chargeback models in capacity planning?

Encourages teams to right-size resources by making costs visible

Eliminates the need for resource monitoring

Allows unlimited resource consumption without accountability

Replaces technical capacity planning entirely

4. Elasticity in cloud computing enables what aspect of capacity planning?

Dynamic adjustment of resources based on real-time demand fluctuations

Permanent allocation of fixed resources

Elimination of the need for monitoring

Guaranteed constant performance regardless of load

5. How should capacity planning account for future business growth?

Include growth projections and plan for scalability in architecture design

Assume no growth and resize only when failures occur

Purchase maximum resources immediately

Ignore business forecasts and plan reactively only

6. What does 'rightsizing' a database instance involve?

Matching CPU, memory, and storage to actual query performance needs

Maximizing the instance size regardless of usage

Using only the smallest available instance types

Avoiding database optimization altogether

7. Reserved instances help with capacity planning by providing what benefit?

Cost discounts and guaranteed resource availability for predictable workloads

Unlimited scaling without any constraints

Automatic right-sizing without user intervention

Elimination of all performance monitoring requirements

8. Which approach best addresses the 'noisy neighbor' problem in shared cloud environments?

Right-sizing and resource isolation through proper instance selection

Accepting performance degradation as normal

Moving all workloads to on-premises infrastructure

Disabling monitoring and alerting systems

9. Burst capacity in cloud architecture serves what primary purpose?

To handle temporary traffic spikes without permanent resource increases

To permanently increase baseline resources

To eliminate the need for monitoring

To reduce security measures during peak times

10. What is 'cost optimization' as it relates to right-sizing?

Matching resource allocation to actual workload needs to reduce waste

Always purchasing the cheapest instances available

Eliminating all redundancy and backups

Negotiating lower cloud provider rates exclusively

11. What is the primary goal of capacity planning in cloud environments?

To match resource supply with anticipated demand while minimizing costs

To purchase the maximum number of resources available

To eliminate all unused resources immediately

To prevent any scaling operations

12. Which metric indicates when a resource needs immediate right-sizing?

Consistently high utilization (>80%) or frequent throttling

Any utilization above 10%

Resources being idle for one day

Random spikes in network traffic

13. What is the relationship between SLA requirements and capacity planning?

SLA targets dictate minimum capacity and redundancy levels needed

SLAs are irrelevant to capacity decisions

SLAs only affect billing

Capacity planning determines SLA requirements

14. Which tool or practice is essential for accurate capacity forecasting?

Historical data analysis and trend prediction modeling

Random resource allocation

Ignoring past usage patterns

Only considering peak load days

15. How does 'horizontal scaling' differ from vertical scaling?

Horizontal adds more instances; vertical increases resources per instance

They are identical approaches

Horizontal is only for databases

Vertical scaling is always superior

16. What is 'vertical scaling' in the context of capacity planning?

Increasing CPU, memory, or storage on existing instances

Adding more instances to a load balancer

Moving workloads to a different cloud provider

Reducing the number of availability zones

17. Right-sizing should consider which of the following factors?

Current utilization, growth trends, and application requirements

Only the current month's usage

The vendor's marketing recommendations exclusively

Administrator preferences alone

18. Which approach helps identify underutilized cloud resources?

Continuous monitoring and analysis of performance metrics

Reducing all instance sizes by half

Eliminating backup systems

Increasing network bandwidth limits

19. What does 'overprovisioning' in cloud architecture typically result in?

Wasted resources and unnecessary costs

Improved application performance

Reduced security vulnerabilities

Better disaster recovery outcomes

20. Which metric is most critical when right-sizing cloud instances?

CPU utilization and memory usage patterns

The brand of the hypervisor

The physical location of data centers

The number of administrators managing resources
