Practice Test
True or False: The cost of your Azure services is not affected by the type of resources you use.
- True
- False
Answer: False
Explanation: The type of resources you use largely determine your Azure services cost. More sophisticated or large-scale resources generally cost more.
Which of the following factors can affect costs in Azure?
- A. Resource Type
- B. Resource Location
- C. Resource Size
- D. All of the above
Answer: D. All of the above
Explanation: Costs in Azure can be affected by the type, size, and location of the resources used.
True or False: The Azure Cost Management tool helps in monitoring and controlling Azure spending.
- True
- False
Answer: True
Explanation: Azure Cost Management provides tools to monitor, allocate, and optimize costs, helping to control Azure spending effectively.
Which of the following can reduce costs in Azure?
- A. Increase the number of resources
- B. Using Reserved Instance
- C. Always running resources even when not in use
- D. Not monitoring your cost management
Answer: B. Using Reserved Instance
Explanation: Reserved instances allow you to commit to usage of certain services for 1 or 3 years with substantial cost savings.
True or False: The Azure location does not impact the cost of services.
- True
- False
Answer: False
Explanation: The cost of Azure services can vary by location due to factors like infrastructure costs, local tax regulations, and currency exchange rates.
Which of the following is a cost optimization strategy in Azure?
- A. Over provisioning resources
- B. Choosing low-cost locations for all resources
- C. Using “Pay-as-you-go” pricing model for long term tasks
- D. Right-sizing and scaling down underused resources.
Answer: D. Right-sizing and scaling down underused resources.
Explanation: Right-sizing allows to match the resource with the demands at lowest cost. Over-provisioning, choosing a low-cost location without considering latency and using pay-as-you-go for long-term projects are typically not efficient strategies.
True or False: Lifecycles of resources do not impact costs in Azure.
- True
- False
Answer: False
Explanation: Lifecycles of resources actually do impact costs. If resources are not decommissioned after use, they can continue to accrue costs.
Which of the following Azure pricing models allow cost-saving when using services for long-term?
- A. Pay-as-you-go pricing
- B. Reserved instances pricing
- C. Spot pricing
- D. Consumption pricing
Answer: B. Reserved instances pricing
Explanation: Reserved Instances allow you to make a low-priority, long-term commitment to usage of certain Azure services, which can significantly lower costs.
True or False: Scaling out your applications can result in increased costs.
- True
- False
Answer: True
Explanation: Scaling out, or adding more instances of your application, can result in higher costs as it leads to increased resource usage.
The Azure Hybrid Benefit lets you save money by:
- A. Applying Windows Server licenses with Software Assurance
- B. Using open-source software
- C. Scaling down resources
- D. Migrating to a less expensive region
Answer: A. Applying Windows Server licenses with Software Assurance
Explanation: The Azure Hybrid Benefit allows you to apply your Windows Server licenses with Software Assurance to virtual machines in Azure, offering significant savings.
True or False: Running your Azure Virtual Machines 24/7 will cost the same as only running them when needed.
- True
- False
Answer: False
Explanation: The cost of running your Virtual Machines in Azure depends on how much you use them. Running them only when needed can significantly reduce costs.
In Azure, savings can be achieved by:
- A. Monolithic architectures
- B. Ignoring Infrastructure as Code(IMaC)
- C. DevOps culture and practices
- D. Avoiding Azure Advisor
Answer: C. DevOps culture and practices
Explanation: DevOps helps organizations create software faster and more reliably, which can significantly reduce costs by avoiding downtime and increasing efficiency.
Which Azure service can help users to identify and annihilate superfluous costs?
- A. Azure Advisor
- B. Azure VM
- C. Azure Policy
- D. Azure Quantum
Answer: A. Azure Advisor
Explanation: Azure Advisor provides personalized best practices to help user optimise Azure resources for high availability, security, performance and cost.
True or False: Implementing ‘autoscaling’ can be a cost optimization strategy in Azure.
- True
- False
Answer: True
Explanation: Auto scaling enables applications to scale in and out automatically based on predefined rules where resources can be added or reduced as needed. This strategy can lead to cost savings in Azure.
Which of the following factors can affect the cost of Azure storage?
- A. The volume of data stored
- B. The type of redundancy chosen
- C. The storage tier chosen
- D. All of the above
Answer: D. All of the above
Explanation: All these factors – the volume of data, redundancy type, and storage tier – affect the cost of Azure storage. Choosing options wisely according to the business needs can help optimize costs.
Interview Questions
What is a major factor that affects costs in Azure?
The resources you use are some of the major factors that affect costs in Azure. This includes the number and type of Azure services you use, how long you use them for, and the configuration of these services.
How does the usage duration of Azure resources affect costs?
The cost of most Azure services is based on usage duration. The longer you use a resource, the more it costs. Turning off resources when they’re not in use can help reduce costs.
How can the Azure region affect costs?
Costs in Azure can vary based on the region. Some services might cost more in certain regions due to factors like operational costs, demand, and local regulations.
How does the type of Azure subscription affect costs?
Different types of Azure subscriptions such as Pay-As-You-Go, Enterprise Agreement, and Azure in Open have different pricing structures which can impact the total cost.
How does the scalability of Azure services affect costs?
If a service is more scalable, it can typically handle more work, but it will also be more costly. It’s crucial to strike a balance between performance and cost-efficiency.
How can Reserved Instances help in managing Azure costs?
Reserved Instances are a way to reserve Azure resources over a long period, typically one or three years, in exchange for substantial cost savings. This feature allows businesses to manage and predict their Azure costs more effectively.
Does data transfer and bandwidth usage affect Azure costs?
Yes, in and outbound data transfer (bandwidth usage) can affect the cost. Data transfer within the same Azure region is typically free, while transferring data out of Azure or across different regions incurs charges.
What is the effect of Azure Support plans on costs?
Azure Support plans are billed at a flat monthly rate and any support incidents initiated during the term are charged as per the plan. Higher level support plans offer faster response times, but also have a higher cost.
Does deploying redundant resources affect Azure costs?
Yes, deploying redundant resources can provide increased reliability and availability, but it can also increase costs because multiple instances of the resource are being utilized.
How does the pricing tier of Azure services affect costs?
Azure services often have several pricing tiers each offering a different level of features, performance, and scalability. A higher pricing tier typically offers more advanced features and better performance, but at an increased cost.
How can Azure Cost Management tools help control costs in Azure?
Azure Cost Management tools offer a range of services such as cost analysis, budgets, and cost alerts that can help track and optimize your Azure spending, hence controlling costs.
How does the use of premium services affect costs in Azure?
Premium services on Azure typically come with increased costs as they offer greater performance, higher SLAs, or additional features compared to standard or basic services.
How can Azure Hybrid Benefit help reduce costs?
Azure Hybrid Benefit allows customers with Software Assurance to use their on-premises Windows Server and SQL Server licenses on Azure, potentially leading to substantial cost savings.
How does compute size in Azure affect costs?
The compute size (or SKU) selected for a given Azure service determines the cost. More powerful SKUs provide higher performance but also come at a higher price.
Can Azure provide cost predictions to help manage costs?
Yes, Azure Cost Management offers a cost forecasting feature to predict future spending based on historical data. This helps businesses better manage their cloud budgets.
