Which is the most efficient way for the testing team to save costs on virtual machines on weekends, when testers are not at work? A) Delete the virtual machines before the weekend and create a new set the following week. B) Deallocate virtual machines when they're not in use. C) Just let everything run. Azure bills you only for the CPU time that you use.
ANSWER B) Deallocate virtual machines when they're not in use. -- When you deallocate virtual machines, the associated hard disks and data are still kept in Azure. But you don't pay for CPU or network consumption, which can help save costs. EXPLANATION for incorrect choices: A) Delete the virtual machines before the weekend and create a new set the following week. -- Although you can delete your virtual machines when they're not in use, you also lose any associated hard disks. It can take some time to re-create the environment at the start of each week. C) Just let everything run. Azure bills you only for the CPU time that you use. -- Usage meters track not only CPU time but also network traffic and the number of disk operations.
Adding a third virtual machine reduces the composite SLA. How can Tailwind Traders offset this reduction? A) Increase the size of each virtual machine. B) Deploy extra instances of the same virtual machines across the different availability zones in the same Azure region. C) Do nothing. Using Azure Load Balancer increases the SLA for virtual machines.
ANSWER B) Deploy extra instances of the same virtual machines across the different availability zones in the same Azure region. -- If one availability zone is affected, your virtual machine instance in the other availability zone should be unaffected. EXPLANATION for wrong choices: A) Increase the size of each virtual machine. -- Incorrect. The size of a virtual machine does not affect its SLA. C) Do nothing. Using Azure Load Balancer increases the SLA for virtual machines. -- Incorrect. Although Load Balancer can improve performance by distributing traffic, each service factors separately into the overall SLA.
Which is the best first step the team should take to compare the cost of running these environments on Azure versus in their datacenter? A) They're just test environments. Spin them up and check the bill at the end of the month. B) Assume that running in the cloud costs about the same as running in the datacenter. C) Run the Total Cost of Ownership Calculator.
ANSWER C) Run the Total Cost of Ownership Calculator. -- Running the Total Cost of Ownership Calculator is a great first step because it can provide an accurate comparison of running workloads in the datacenter versus on Azure, certified by an independent research company. EXPLANATION of incorrect answers: A) They're just test environments. Spin them up and check the bill at the end of the month. -- Costs can add up. It's important to understand the full cost of running your solution, whether it's in the datacenter or in the cloud. B) Assume that running in the cloud costs about the same as running in the datacenter. -- Running on Azure can actually save money. But only a thorough cost assessment can tell you with certainty.
What approach might the company take in adding the augmented reality (AR) preview service to its architecture? A) The Special Orders app is already in production.

The company can integrate the AR service now because potential downtime or failures aren't an important factor. C) The development team can create a prototype version of the app that includes the AR service that it tests out with select retail employees.
ANSWER C) The development team can create a prototype version of the app that includes the AR service that it tests out with select retail employees. -- After the AR service reaches general availability (GA), the team can roll it out to production. EXPLANATION for incorrect answers: A) The Special Orders app is already in production. The company shouldn't look into the AR service until the service reaches general availability (GA). -- Although you don't want to rely on preview services in production, are there ways that the team can begin to at least explore the service? B) The Special Orders app is mainly for use by retail employees. The company can integrate the AR service now because potential downtime or failures aren't an important factor. -- Even though the app is used primarily by retail employees, it's still critical to the business. If the app isn't available or it fails, customers will be disappointed or go to a competitor.

Which is the best way for Tailwind Traders to ensure that the team deploys only cost-effective virtual machine SKU sizes? A) Create a policy in Azure Policy that specifies the allowed SKU sizes. B) Periodically inspect the deployment manually to see which SKU sizes are used. C) Create an Azure RBAC role that defines the allowed virtual machine SKU sizes.
ANSWER: A) Create a policy in Azure Policy that specifies the allowed SKU sizes. -- After you enable this policy, that policy is applied when you create new virtual machines or resize existing ones. Azure Policy also evaluates any current virtual machines in your environment. EXPLANATION for bad answers: B) Periodically inspect the deployment manually to see which SKU sizes are used. -- Is there a more automated way to verify that allowed SKU sizes are used before virtual machines are deployed? C) Create an Azure RBAC role that defines the allowed virtual machine SKU sizes. -- Azure RBAC enables you to create roles that define access permissions, but it doesn't enable you to define allowed virtual machine SKU sizes.
