Q42. DRAG DROP - (Topic 6)
You have a website that displays text, pictures, video files, and audio files. The website processes requests from countries and regions all over the world. You plan to migrate the website to the Azure platform.
The website has the following requirements:
✑ Encode, store, and stream audio and video at scale.
✑ Load-balance communications with the website instance that is closest to the user's location.
✑ Deliver content with high-bandwidth and low latency.
You need to recommend the technologies to implement the solution.
Which technologies should you recommend? To answer, drag the appropriate technology to the correct requirement. Each technology may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Answer:
Explanation:
* MediaServices
Azure Media Services is being used to power consumer and enterprise streaming solutions worldwide. Combining powerful and highly scalable cloud-based encoding, encryption and steaming components, Azure Media Services is helping customers with valuable and premium video content to easily reach larger audiences on today’s most popular digital devices, such as tablets and mobile phones.
Q43. DRAG DROP - (Topic 7)
You need to configure Azure Security Center to assist the CSIRT team.
Which services should you implement? To answer, drag the appropriate Azure Security Center services to the correct key security areas. Each service may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Q44. - (Topic 6)
A company hosts a website and exposes web services on the company intranet.
The intranet is secured by using a firewall. Company policies prohibit changes to firewall rules.
Devices outside the firewall must be able to access the web services. You need to recommend an approach to enable inbound communication. What should you recommend?
A. The Azure Access Control Service
B. Windows Azure Pack
C. The Azure Service Bus
D. A web service in an Azure role that relays data to the internal web services
Answer: C
Explanation: The Service Bus Relay is designed for the use-case of taking existing Windows Communication Foundation (WCF) web services and making those services securely accessible to solutions that reside outside the corporate perimeter without requiring intrusive changes to the corporate network infrastructure. Such Service Bus relay services are still hosted inside their existing environment, but they delegate listening for incoming sessions and requests to the cloud-hosted Service Bus.

Q45. - (Topic 4)
You need to recommend an appropriate solution for the data mining requirements. Which solution should you recommend?
A. Design a schedule process that allocates tasks to multiple virtual machines, and use the Azure Portal to create new VMs as needed.
B. Use Azure HPC Scheduler Tools to schedule jobs and automate scaling of virtual machines.
C. Use Traffic Manager to allocate tasks to multiple virtual machines, and use the Azure Portal to spin up new virtual machines as needed.
D. Use Windows Server HPC Pack on-premises to schedule jobs and automate scaling of virtual machines in Azure.
Answer: C
Explanation: * Microsoft Azure Traffic Manager allows you to control the distribution of user traffic to your specified endpoints, which can include Azure cloud services, websites, and other endpoints. Traffic Manager works by applying an intelligent policy engine to Domain Name System (DNS) queries for the domain names of your Internet resources. Your Azure cloud services or websites can be running in different datacenters across the world.
* Scenario:
Virtual machines:
✑ The data mining solution must support the use of hundreds to thousands of processing cores.
✑ Minimize the number of virtual machines by using more powerful virtual machines.
Each virtual machine must always have eight or more processor cores available.
✑ Allow the number of processor cores dedicated to an analysis to grow and shrink automatically based on the demand of the analysis.
✑ Virtual machines must use remote memory direct access to improve performance.
Task scheduling:
The solution must automatically schedule jobs. The scheduler must distribute the jobs based on the demand and available resources.

Q46. DRAG DROP - (Topic 6)
You manage a large number of on-premises applications. You plan to migrate the applications to Azure.
You need to implement Azure Storage for each type of data that the applications use.
For each type of data, which storage mechanism should you use? To answer, drag the appropriate storage mechanism to the correct type of data. Each storage mechanism may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Answer:
Q47. DRAG DROP - (Topic 8)
You need to scale the API.
In the Azure portal, which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Q48. - (Topic 6)
An application currently resides on an on-premises virtual machine that has 2 CPU cores, 4 GB of RAM, 20 GB of hard disk space, and a 10 megabit/second network connection.
You plan to migrate the application to Azure. You have the following requirements:
✑ You must not make changes to the application.
✑ You must minimize the costs for hosting the application.
You need to recommend the appropriate virtual machine instance type. Which virtual machine tier should you recommend?
A. Network Optimized (A Series)
B. General Purpose Compute, Basic Tier (A Series)
C. General Purpose Compute, Standard Tier (A Series)
D. Optimized Compute (D Series)
Answer: B
Explanation: General purpose compute: Basic tier
An economical option for development workloads, test servers, and other applications that don't require load balancing, auto-scaling, or memory-intensive virtual machines.
CPU core range: 1-8 RAM range: 0.75 – 14 GB
Disk size: 20-240 GB

Q49. HOTSPOT - (Topic 4)
You need to recommend strategies for storing data.
Which services should you recommend? To answer, select the appropriate storage technology for each data type in the answer area.
Answer:
Explanation:
* Media metadata: Azure Queue Storage Service
Scenario: Media metadata must be stored in Azure Table storage.
Azure Queues provide a uniform and consistent programming model across queues, tables, and BLOBs – both for developers and for operations teams.
* Images: Azure Mobile Services
Scenario: Media files must be stored in Azure BLOB storage.
You can use Azure Mobile Services to access images from mobile devices.
* Audio: Azure Media Services
* Video: Azure Media Services
Microsoft Azure Media Services is an extensible cloud-based platform that enables developers to build scalable media management and delivery applications. Media Services is based on REST APIs that enable you to securely upload, store, encode and package video or audio content for both on-demand and live streaming delivery to various clients (for example, TV, PC, and mobile devices).
