Question : Your role of Systems Administrator at ABC.com includes the management of the company's private and public clouds. The private clouds are hosted in a data center at the company's headquarters. A physical server named TK-SQL1 runs Windows Server 2012 and SQL Server 2012. TK-SQL1 is hosted in the datacenter. You have an application that runs in Azure Cloud Services. The cloud service consists of two A1 virtual machine instances. The application copies data to a SQL Server database hosted on TK-SQL1. Users complain that the application runs slowly when it is copying data to TK-SQL1. You want to reduce the time it takes the application to copy data to TK-SQL1. Which of the following actions should you perform?
1. Allocate additional processors to the virtual machines. 2. Deploy the application as two A3 instances. 3. Deploy the application as two A0 instances. 4. Deploy a third A1 instance of the application.
Correct Answer : 2 Explanation: Basic Compute Tier: This new tier of compute instances is similar in configuration to the Standard tier with lower prices. These instances do not include load balancer and auto-scaling. They are well-suited for single instance production applications, development workloads, test servers and batch processing applications that might not require these features. The basic compute tier is currently available only for the General Purpose Instances. These instances range from Basic A0 to Basic A4.
Standard Compute Tier: This tier of compute instances provides an optimal set of compute, memory and I/O resources for running a wide array of applications. These instances include both auto-scaling and load balancing capabilities at no additional cost. The standard compute tier is available across General Purpose, Memory Intensive and Compute Intensive instances. These instances range from Standard A0 to Standard A7.
There are several important advantages to hosting your SQL Server infrastructure on a Windows Azure Virtual Machine. First, you have no capital costs for storage or hardware, along with no ongoing maintenance of the storage or hardware. Second, you have no OS or SQL Server license costs (when you use a SQL image from the standard Azure VM gallery). Third, you can create a new Azure VM that already has SQL Server installed in a few minutes (even though it may take a little longer to completely configure the OS and the SQL Server instance to your exact requirements). Going forward, it will still be up to you to install Windows and SQL Server updates, but you won't have to worry about things like firmware, BIOS, or driver updates.
Question : You work as a network administrator at ABC.com. The corporate network consists of physical and virtual servers located in a datacenter and a public cloud hosted on Microsoft Azure.The company has a Development department. Users in the Development department develop custom applications that are used within the company. One custom application is named CorpApp1. The application is hosted in Azure Cloud Services. The developers release an updated version of CorpApp1. You need to deploy the updated version of CorpApp1 to Azure cloud services for a period of time to allow for testing. During testing, the current version of CorpApp1 must remain online. After testing, the new version must replace the current version as the live version with the minimum amount of downtime. When the new version is live, the old version must remain available for a period of time to be redeployed in the event of problems with the new version. The solution must minimize costs, administrative effort and application downtime. Which of the following actions should you perform? (Choose all that apply)
A. Deploy the new application to a new cloud service. B. Deploy the new application to the production area. C. Deploy the new application to the staging area. D. Move the old version of the application to a new cloud service. E. Perform a Virtual IP swap.
1. A,B 2. B,C 3. C,D 4. D,E 5. C,E
Correct Answer : 5 Explanation: The Swap Deployment asynchronous operation initiates a virtual IP address swap between the staging and production deployment environments for a service. If the service is currently running in the staging environment, it will be swapped to the production environment. If it is running in the production environment, it will be swapped to staging.
If the Swap Deployment operation is specified with deployment names that do not match what is currently in production and staging, status code 409 (Conflict) is returned. You can swap VIP addresses only if the number of endpoints specified by the service definition is identical for both deployments. For example, if you add an HTTPS endpoint to a web role that previously exposed only an HTTP endpoint, you cannot upgrade your service by swapping VIP addresses; you must delete your production deployment and redeploy instead. You can obtain information about endpoints that are used by using the Get Deployment operation.
Question : You work as a network administrator at ABC.com. The corporate network consists of physical and virtual servers located in a datacenter and applications running in Microsoft Azure Cloud Services. One new cloud services application has an HTTPS endpoint to provide encrypted access for users. You need to provide an x.509 certificate to be used by the application for SSL access. How can you ensure that the certificate can be accessed by the application? 1. Redeploy the application package to include the certificate. 2. Upload the certificate to the staging area. 3. Use the management portal to upload the certificate. 4. Use the management portal to upload the public key of the certificate.
Correct Answer : 3 Explanation: To configure SSL for an application, you first need to get an SSL certificate that has been signed by a Certificate Authority (CA), a trusted third-party who issues certificates for this purpose. If you do not already have one, you will need to obtain one from a company that sells SSL certificates.
The certificate must meet the following requirements for SSL certificates in Azure:
The certificate must contain a private key. The certificate must be created for key exchange, exportable to a Personal Information Exchange (.pfx) file. The certificate's subject name must match the domain used to access the cloud service. You cannot obtain an SSL certificate from a certificate authority (CA) for the cloudapp.net domain. You must acquire a custom domain name to use when access your service. When you request a certificate from a CA the certificate's subject name must match the custom domain name used to access your application. For example, if your custom domain name is contoso.com you would request a certificate from your CA for *.contoso.com or www.contoso.com. The certificate must use a minimum of 2048-bit encryption. For test purposes, you can create and use a self-signed certificate. A self-signed certificate is not authenticated through a CA and can use the cloudapp.net domain as the website URL. For example, the task below uses a self-signed certificate in which the common name (CN) used in the certificate is sslexample.cloudapp.net.
Next, you must include information about the certificate in your service definition and service configuration files.
Step 2: Modify the service definition and configuration files Step 3: Upload a certificate Your deployment package has been updated to use the certificate, and an HTTPS endpoint has been added. Now you can upload the package and certificate to Azure with the Management Portal.
Log into the Azure Management Portal. Click on Cloud Services on the left-side navigation pane. Click on the desired cloud service. Click on the Certificates tab.
Click the Certificates tab
Click the Upload button.
