AZ-700 Exam Dumps - Microsoft Certified: Azure Network Engineer Associate Questions and Answers

Here are the steps and explanations for ensuring that connections to the storage34280945 storage account can be made by using an IP address in the 10.1.1.0/24 range and the name stor-age34280945.pnvatelinlcblob.core.windows.net:

To allow access from a specific IP address range, you need to configure the Azure Storage firewall and virtual network settings for your storage account. You can do this in the Azure portal by selecting your storage account and then selecting Networking under Settings1.

On the Networking page, select Firewalls and virtual networks, and then select Selected networks under Allow access from1. This will block all access to your storage account except from the networks or resources that you specify.

Under Firewall, select Add rule, and then enter 10.1.1.0/24 as the IP address or range. You can also enter an optional rule name and description1. This will allow access from any IP address in the 10.1.1.0/24 range.

Select Save to apply your changes1.

To map a custom domain name to your storage account, you need to create a CNAME record with your domain provider that points to your storage account endpoint2. A CNAME record is a type of DNS record that maps a source domain name to a destination domain name.

Sign in to your domain registrar’s website, and then go to the page for managing DNS settings2.

Create a CNAME record with the following information2:

Source domain name: stor-age34280945.pnvatelinlcblob.core.windows.net

Destination domain name: stor-age34280945.pnvatelinlcblob.core.windows.net

Save your changes and wait for the DNS propagation to take effect2.

To register the custom domain name with Azure, you need to go back to the Azure portal and select your storage account. Then select Custom domain under Blob service2.

On the Custom domain page, enter stor-age34280945.pnvatelinlcblob.core.windows.net as the custom domain name and select Save2.

To minimize the risk of SNAT port exhaustion for your 100 virtual machines in subnet4-1, while ensuring minimal administrative effort, you can use an Azure NAT Gateway. This service provides scalable and resilient outbound connectivity for virtual networks, dynamically allocating SNAT ports to avoid exhaustion.

Navigate to the Azure Portal.

Search for “NAT gateways” and select it.

Click on “Create”.

Enter the following details:

Subscription: Select your subscription.

Resource Group: Select an existing resource group or create a new one.

Name: Enter a name for the NAT gateway (e.g., NATGateway-Subnet4-1).

Region: Select the region where your virtual network is located.

Click on “Next: Outbound IP”.

Choose whether to use existing public IP addresses or create new ones.

If creating new ones, click on “Add new” and configure the new public IP addresses.

Click on “Next: Subnet”.

Click on “Associate subnet”.

Select the virtual network that contains subnet4-1.

Select subnet4-1 from the list of subnets.

Click on “OK”.

Review your settings to ensure everything is correct.

Click on “Review + create” and then “Create”.

Azure NAT Gateway: This service provides outbound connectivity for virtual networks, dynamically allocating SNAT ports across all VM instances within a subnet. This dynamic allocation helps prevent SNAT port exhaustion, especially in scenarios with high outbound connection volumes12.

Dynamic SNAT Port Allocation: Unlike static allocation methods, NAT Gateway dynamically allocates SNAT ports based on demand, ensuring efficient use of available ports and reducing the risk of exhaustion2.

Step-by-Step SolutionStep 1: Create a NAT GatewayStep 2: Configure Outbound IP AddressesStep 3: Associate the NAT Gateway with Subnet4-1Step 4: Review and CreateExplanationBy following these steps, you can ensure that your 100 virtual machines in subnet4-1 can make the necessary API calls without running into SNAT port exhaustion, all while minimizing administrative effort.

To archive all the metrics of VNET1 to an existing storage account, you can use Azure Monitor’s diagnostic settings. Here’s how you can do it:

Step-by-Step Solution

Step 1: Navigate to VNET1 in the Azure Portal

Open the Azure Portal.

Search for “Virtual networks” and select VNET1 from the list.

Step 2: Configure Diagnostic Settings

In the VNET1 blade, select “Diagnostic settings” under the “Monitoring” section.

Click on “Add diagnostic setting”.

Step 3: Set Up the Diagnostic Setting

Enter a name for the diagnostic setting (e.g., VNET1-Metrics-Archive).

Select the metrics you want to archive. You can choose from various metrics like TotalBytesReceived, TotalBytesSent, etc.

Under “Destination details”, select “Archive to a storage account”.

Choose the existing storage account where you want to archive the metrics.

Configure the retention period if needed.

Step 4: Save the Configuration

Review your settings to ensure everything is correct.

Click on “Save” to apply the diagnostic setting.

Explanation

Diagnostic Settings: These allow you to collect and route metrics and logs from your Azure resources to various destinations, including storage accounts, Log Analytics workspaces, and Event Hubs.

Metrics: Metrics provide numerical data about the performance and health of your resources. Archiving these metrics helps in long-term analysis and compliance.

Storage Account: Using an existing storage account ensures that the metrics are stored securely and can be accessed for future analysis.

By following these steps, you can ensure that all the metrics of VNET1 are archived to your existing storage account, enabling you to monitor and analyze the performance and health of your virtual network over time.

To provide a single host name that routes traffic based on the origin, you can use Azure Traffic Manager. This service allows you to route traffic to different endpoints based on various routing methods, including geographic routing.

Navigate to the Azure Portal.

Search for “Traffic Manager profiles” and select it.

Click on “Create”.

Enter the following details:

Name: Enter a name for the Traffic Manager profile (e.g., ContosoTrafficManager).

Routing method: Select Geographic.

Subscription: Select your subscription.

Resource group: Select an existing resource group or create a new one.

Resource group location: Choose a location (this does not affect the routing).

Click on “Create”.

Navigate to the newly created Traffic Manager profile.

Select “Endpoints” from the left-hand menu.

Click on “Add” to add a new endpoint.

Enter the following details:

Type: Select External endpoint.

Name: Enter a name for the endpoint (e.g., NewYorkEndpoint).

FQDN: Enter ny.contoso.com.

Geographic region: Select “World” (this will be adjusted later).

Click on “Add” to save the endpoint.

Repeat the process to add the second endpoint:

Type: Select External endpoint.

Name: Enter a name for the endpoint (e.g., GermanyEndpoint).

FQDN: Enter de.contoso.com.

Geographic region: Select Europe.

Navigate to the Traffic Manager profile.

Select “Configuration” from the left-hand menu.

Under “Geographic routing”, adjust the regions:

For the GermanyEndpoint, ensure that the geographic region is set to Europe.

For the NewYorkEndpoint, ensure that the geographic region is set to World (excluding Europe).

Use a DNS query tool to test the routing.

From a location in Germany, query the Traffic Manager profile’s DNS name and ensure it resolves to de.contoso.com.

From a location outside Europe, query the Traffic Manager profile’s DNS name and ensure it resolves to ny.contoso.com.

Azure Traffic Manager: This service uses DNS to direct client requests to the most appropriate endpoint based on the routing method you choose. Geographic routing ensures that traffic is directed based on the origin of the request.

Geographic Routing: This method allows you to route traffic based on the geographic location of the DNS query origin, ensuring that users are directed to the nearest or most appropriate endpoint.

Step-by-Step SolutionStep 1: Create a Traffic Manager ProfileStep 2: Configure EndpointsStep 3: Adjust Geographic RoutingStep 4: Test the ConfigurationExplanationBy following these steps, you can provide a single host name that routes traffic to de.contoso.com for users in Germany and to ny.contoso.com for users from other locations, ensuring efficient and appropriate traffic management.
