You need to ensure that developers can connect to a Microsoft Azure role by using RDP.

What should you do?

A. Export a certificate with a private key. Upload the .pfx file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.

B. Export a certificate with a private key. Upload the .pfx file to the Management Certificates section on the Azure Management Portal.

C. Export a certificate without a private key. Upload the .cer file to the Management Certificates section on the Azure Management Portal.

D. Export a certificate without a private key. Upload the .cer file to the Certificates section under the TranscodeWorkerRole hosted service on the Azure Management Portal.

Answer: A

Explanation: In case you donu2021t want to use the RDP certificate created by Windows Azure Tools and want to use a custom certificate instead, the following steps will guide you. These steps can also be used in case package is not being published from Visual Studio rather it is being built locally, saved in either Local Machine's Drive or Windows Azure Blob Storage and subsequently published from there.

Here are the steps which are required to get pass the publishing error which you might be running into. You would need to upload the Certificate with Private Key to the portal (when Visual Studio is used this is done in the background).

Detailed steps.

1. In Visual Studio, go to the solution which is being developed.

2. Right click the Web Project -> Configure Remote Desktop -> click on View to see Certificate details (Since I donu2021t have a custom certificate I will use one create by Windows Azure Tools itself)

3. Go to Details tab on Certificate -> Click Copy to file.. -> Next -> Select u2021Yes, export the private keyu2021 -> Next -> Continue with default setting and create a password when asked (please refer below screenshots)

4. These steps will generate a .PFX file for this certificate. Now we need to upload this certificate to the portal (for the respective cloud service)

5. Go to the Azure Management Portal -> Go to the Cloud Service in question -> Certificates Tab -> Upload the newly created certificate (.PFX file)

Note:

* The certificates that you need for a remote desktop connection are different from the certificates that you use for other Azure operations. The remote access certificate must

have a private key.

* Microsoft Azure uses certificates in three ways:

/ Management certificates u2013 Stored at the subscription level, these certificates are used to enable the use of the SDK tools, the Windows Azure Tools for Microsoft Visual Studio, or the Service Management REST API Reference. These certificates are independent of any cloud service or deployment.

/ Service certificates u2013 Stored at the cloud service level, these certificates are used by your deployed services.

/ SSH Keys u2013 Stored on the Linux virtual machine, SSH keys are used to authenticate remote connections to the virtual machine.

You are developing an ASP.NET MVC application. Devices that use many different browsers will use the application.

You have the following requirements:

You need to configure the application.

Which two actions should you perform? Each correct answer presents part of the solution.

A. Use JavaScript to evaluate the window.innerWidth and window.innerHeigh properties.

B. Set the value of the width property for the viewport meta tag to device-width.

C. Use CSS to target the HTML element on each page. Set the values of the width and height properties to 100%.

D. Use CSS media queries to target screen size, device orientation, and other browser capabilities.

Answer: B,D

Explanation:

B: If you want the viewport width to match the deviceu2021s physical pixels, you can specify the following:

<meta name="viewport" content="width=device-width">

For this to work correctly, you must not explicitly force elements to exceed that width (e.g., using a width attribute or CSS property), otherwise the browser will be forced to use a larger viewport regardless.

D: Media queries in CSS3 extend the CSS2 media types idea: Instead of looking for a type of device, they look at the capability of the device.

Media queries can be used to check many things, such as: width and height of the viewport

width and height of the device

orientation (is the tablet/phone in landscape or portrait mode?) resolution

Using media queries are a popular technique for delivering a tailored style sheet to tablets, iPhone, and Androids.
