Question : You work for a company named ABC.com. The company has a main office in New York and branch offices in several countries including UK, Spain, Germany, India and Japan. Your role as Cloud Administrator includes the management of the company's public and private cloud infrastructure. Company employees in every office use mobile devices. The mobile devices run a custom application that sends and retrieves data to and from a web service hosted in a virtual machine (VM) named TK-VM1. TK-VM1 is hosted on Windows Azure. Users in India and Japan report poor performance when accessing the web service from their mobile devices. You need to monitor the performance of the web service from multiple locations around the world. How should you configure the monitoring?
1. You should configure Network Out monitoring. 2. You should configure Network In monitoring. 3. You should configure Disk Write Bytes/sec monitoring. 4. You should configure Endpoint monitoring.
Correct Answer : 4 Explanation: By default, minimal monitoring is provided for a new cloud service using performance counters gathered from the host operating system for the roles instances (virtual machines). The minimal metrics are limited to CPU Percentage, Data In, Data Out, Disk Read Throughput, and Disk Write Throughput. By configuring verbose monitoring, you can receive additional metrics based on performance data within the virtual machines (role instances). The verbose metrics enable closer analysis of issues that occur during application operations.
By default performance counter data from role instances is sampled and transferred from the role instance at 3-minute intervals. When you enable verbose monitoring, the raw performance counter data is aggregated for each role instance and across role instances for each role at intervals of 5 minutes, 1 hour, and 12 hours. The aggregated data is purged after 10 days.
After you enable verbose monitoring, the aggregated monitoring data is stored in tables in your storage account. To enable verbose monitoring for a role, you must configure a diagnostics connection string that links to the storage account. You can use different storage accounts for different roles.
Note that enabling verbose monitoring will increase your storage costs related to data storage, data transfer, and storage transactions. Minimal monitoring does not require a storage account. The data for the metrics that are exposed at the minimal monitoring level are not stored in your storage account, even if you set the monitoring level to verbose.
Using Azure monitoring you can configure metrics such as CPU, Memory, Network, and Disk, and view the performance of your virtual machines in the management portal. Alerts can be configured per metric. Each alert requires a name, metric, threshold, and duration. After the threshold has passed the duration, an alert can email the administrators or co-administrators of the subscription, and you can also specify a specific email address to receive the alert. Use Azure endpoint monitoring to remotely monitor the uptime and response time for up to two endpoints on your virtual machine, from up to three global locations for each endpoint. Enable Azure diagnostics to have a much richer selection of performance counters. Azure diagnostics can also automatically transfer event logs, web logs, and application trace logs to an Azure Storage account. There are several third-party tools that allow you to monitor the diagnostics of a virtual machine.
Question : You work for a company named ABC.com. Your role as Cloud Administrator includes the management of the company's public and private cloud infrastructure. The company has a Windows Azure subscription for each of its three offices. The Windows Azure subscriptions are named NewYork, Boston and Atlanta. You are based in the Atlanta office. Your default subscription for PowerShell sessions is the Atlanta subscription. You need to configure virtual machines in the Boston subscription. You need to configure the Boston subscription to be used by default for the current PowerShell session without c changing the default subscription for all other sessions. Which of the following PowerShell cmdlets should you run?
Correct Answer : 3 Explanation: Select-AzureSubscription Selects or clears a Windows Azure subscription to be used as the current subscription. The Select-AzureSubscription cmdlet selects or clears the subscription to be designated as the current subscription. A current subscription is the one whose settings are available for use by other Windows Azure PowerShell cmdlets. If a subscription is designated as the default subscription, it is automatically made current when starting a Windows PowerShell session or running a script. To set the default subscription, use the DefaultSubscription parameter and specify the name of the subscription to designate as the default. The default subscription setting can be cleared by specifying the NoDefaultSubscription switch parameter. To specify a different subscription for the current session without affecting the default subscription, use Current.
Question : You work for a company named ABC.com. The company has a main office in New York and branch offices Atlanta, Dallas and Seattle. Your role as Cloud Administrator includes the management of the company's public and private cloud infrastructure. The company has virtual machines running in a Windows Azure subscription. Multiple virtual networks are included in the Windows Azure environment. Sales users often work away from the office.You have been asked by the Sales Manager to provide a solution to enable the sales users to access the Azure virtual networks when they are working remotely. The solution must enable the sales users to access the virtual networks from public networks such as coffee shops. Which secure cross-premise connectivity method should you recommend for the Sales users?
Correct Answer : 2 Explanation: If you travel for work or work remotely, you likely use an agent that you run in order to connect to the corporate network. That agent establishes a secure connection to the corporate network, enabling you to access resources even from public locations. That's exactly what a point-to-site network is, it includes an installer that will add a VPN connection. Point-to-site connectivity allows you to connect an individual computer to an Azure virtual network using a secure VPN connection. A self-signed certificate is used for authentication. Site-to-site connectivity allows you to create an industry standard IPSEC VPN connection between one or more networks and an Azure virtual network.
1. By configuring load balancing between the VMs. 2. By moving the VMs to the Azure Basic tier. 3. By removing any orphaned VHDs. 4. By reducing the CPU count of the VMs.
