Suppose you have an existing application running locally on your own server. You need additional capacity but prefer to move to Azure instead of buying upgraded on-premises hardware. Which compute option would likely give you the quickest route to getting your application running in Azure?

• Serverless computing

• Containers

• Virtual machines

Imagine that you work on a photo-sharing application that runs on millions of mobile devices. Demand is unpredictable because you see a spike in usage whenever a locally or nationally significant event occurs. Which Azure compute resource is the best match for this workload?

• Serverless computing

• Containers

• Virtual machines

The compute options give you different levels of control over the configuration of the environment in which your application runs. Which of the following lists the compute options in order of your control from "most control" to "least control"?

• Serverless computing, containers, virtual machines

• Containers, serverless computing, virtual machines

• Virtual machines, containers, serverless computing

Suppose you work at a startup with limited funding. Why might you prefer Azure data storage over an on-premises solution?

• To ensure you run on a specific brand of hardware, which will let you form a marketing partnership with that hardware vendor.

• The Azure pay-as-you-go billing model lets you avoid buying expensive hardware.

• To get exact control over the location of your data store.

Which of the following situations would yield the most benefits from relocating an on-premises data store to Azure?

• Unpredictable storage demand that increases and decreases multiple times throughout the year.

• Long-term, steady growth in storage demand.

• Consistent, unchanging storage demand.

A newly released mobile app using Azure data storage has just been mentioned by a celebrity on social media, seeing a huge spike in user volume. To meet the unexpected new user demand, what feature of pay-as-you-go storage will be most beneficial?

• The ability to provision and deploy new infrastructure quickly

• The ability to predict the service costs in advance

• The ability to meet compliance requirements for data storage

What is an Azure region?

• One or more Azure data centers within a specific geographical location.

• A way of breaking networks into smaller networks.

• Firewall rules which define the flow of traffic in and out of Azure.

Which of the following is true about virtual networks?

• You configure virtual networks through software.

• A virtual network accepts network traffic on all ports. You configure the firewall through virtual machines.

• Virtual networks are always reachable from the internet.

Which is true about Azure Load Balancer?

• You must use Azure Load Balancer if you want to distribute traffic among your virtual machines running in Azure.

• Azure Load Balancer works with internet-facing traffic only.

• Azure Load Balancer distributes traffic among similar systems, making your services more highly available.

What is network latency?

• The amount of data that can fit on the connection.

• The distance data must travel to reach its destination.

• The time it takes for data to travel over the network.
