Question 881
Tradewind Traders has recently migrated to Azure cloud services. The company is reviewing its support plans. You have been asked to determine which support plan will provide best practice information, health status and notifications, and 24/7 access to billing information at the lowest possible cost. Which support plan should you choose?
A. Standard support plan
B. Basic
C. Developer
D. Premier
Answer
B. Basic
Explanation
Developer support is chargeable and also provides support for Third-party software with interoperability and configuration guidance and troubleshooting.
Question 882
Tradewind Traders is planning to migrate some of their data and resources to Azure cloud services, Management has asked you to design a deployment plan that will guarantee services running on virtual machines will continue to operate in the event a single datacenter fails. As part of this design, you will deploy virtual machines to two or more availability zones.
Does this design meet the requirements of the Organisation?
A. Yes
B. No
Answer
A. Yes
Explanation
Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. An Availability Zone is a physically separate zone, within an Azure region. Each Availability Zone has a distinct power source, network, and cooling.
Question 883
Tradewind Traders has recently migrated some of its data and resources to Azure cloud services. The company requires a solution that will allow for automation of the deployment of similar resources across multiple business units. Which of the following solutions should you recommend?
A. Azure API Management service
B. Virtual machine scale sets
C. Azure Resource Manager templates
D. Management groups
Answer
C. Azure Resource Manager templates
Explanation
You can use Azure Resource Manager templates to automate the creation of the Azure resources. Deploying resources through templates is known as Infrastructure as code.
Question 884
Tradewind Traders has recently migrated to Azure cloud services. The company is reviewing its support plans. You have been asked to identify the lowest-cost support plan that allows 24 x7 access to support engineers by phone. Which of the following support options allow this at a low cost?
A. Azure Developer support plan
B. Azure Professional Direct support plan
C. Azure Standard support plan
D. Azure Basic support plan
Answer
C. Azure Standard support plan
Explanation
The Basic support plan is free so is, therefore, the cheapest. The Developer support plan is the cheapest paid-for support plan. The order of support plans in terms of cost ranging from the cheapest to most expensive is Basic, Developer, Standard, Professional Direct, Premier. However, 24/7 access to technical support by email and phone is only available for Standard, Professional Direct, Premier plans.
Question 885
Tradewind Traders is planning to migrate to Azure cloud services. Management has asked you to research some of the main features of cloud services. Based on your research, which of the following statements is correct?
A. An Azure region contains one or more datacenters that are connected by using a high-latency network.
B. An Azure region is found in each country where Microsoft has a subsidiary office.
C. An Azure region contains one or more datacenters that are connected by using a low-latency network.
D. An Azure region can be found in every country in Europe and the Americas only.
Answer
C. An Azure region contains one or more datacenters that are connected by using a low-latency network.
Explanation
An Azure region is a set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
Question 886
You have built a solution that detects objects in images. You are using the same endpoint and key to predict as you used when you trained the model. What type of service are you using?
A. Cognitive Service
B. Computer Vision
C. Custom Vision
Answer
A. Cognitive Service
Explanation
The simplest approach is to use a general Cognitive Services resource for both training and prediction.
Question 887
You plan on using object detection. After you have trained your model, you want to assess the performance of the model. Which performance metrics are available for you to analyze?
Select all options that apply.
A. Precision
B. Recall
C. Mean average precision
D. Project ID
Answer
A. Precision
B. Recall
C. Mean average precision
Explanation
At the end of the training process, the performance for the trained model is indicated by the following evaluation metrics: precision, recall, and mean average precision (mAP).
Question 888
You created a solution the makes use of object detection. You deployed two separate resources in Azure -one that manages the training of the model, and one that manages the predictions. To which endpoint should you make calls to generate predictions?
A. Training endpoint
B. Prediction endpoint
C. Any endpoint (prediction or training), both will work
Answer
B. Prediction endpoint
Explanation
To generate predictions, it must be used the HTTP address of the endpoint for the prediction resource to which you published the model.
Question 889
Object detection is a form of machine learning-based computer vision in which a model is trained to recognize individual types of objects in an image, and to identify their location in the image. True or False?
A. True
B. False
Answer
A. True
Explanation
Object detection is a form of machine learning-based computer vision in which a model is trained to recognize individual types of objects in an image, and to identify their location in the image.
Question 890
Which of the following application examples are a good fit to use object detection?
Select all options that apply.
A. Medical imaging such as an MRI or x-rays that can detect known objects for medical diagnosis
B. Creating software for self-driving cars or vehicles with lane assist capabilities
C. Determining the color of clothes
D. Evaluating the safety of a building by looking for fire extinguishers or other emergency equipment
Answer
A. Medical imaging such as an MRI or x-rays that can detect known objects for medical diagnosis
