Business Requirements

Litware wants to minimize costs whenever possible, as long as all other requirements are met.

Virtual Networking Requirements

Litware identifies the following virtual networking requirements:

* Direct the default route of 0.0.0.0/0 on Vnet2 and Vnet3 to the Boston datacenter over an ExpressRoute circuit.

* Ensure that the records in the cloud.litwareinc.com zone can be resolved from the on-premises locations.

* Automatically register the DNS names of Azure virtual machines to the cloud.litwareinc.com zone.

* Minimize the size of the subnets allocated to platform-managed services.

* Allow traffic from VMScaleSet1 to VMScaleSet2 on the TCP port 443 only.

Hybrid Networking Requirements

Litware identifies the following hybrid networking requirements:

* Users must be able to connect to Vnet1 by using a Point-to-Site (P2S) VPN when working remotely. Connections must be authenticated by Azure AD.

* Latency of the traffic between the Boston datacenter and all the virtual networks must be minimized.

* The Boston datacenter must connect to the Azure virtual networks by using an ExpressRoute FastPath connection.

* Traffic between Vnet2 and Vnet3 must be routed through Vnet1.

Explanation:

For the first question, only ExpressRoute GW SKU Ultra Performance support FastPath feature. For the second question, vnet1 will connect to ExpressRoute gw, once Vnet1 peers with Vnet2, the traffic from on-premise network will bypass GW and Vnet1, directly goes to Vnet2, while this feature is under public preview.

Reference: ExpressRoute virtual network gateway is designed to exchange network routes and route network traffic. FastPath is designed to improve the data path performance between your on-premises network and your virtual network. When enabled, FastPath sends network traffic directly to virtual machines in the virtual network, bypassing the gateway.

To configure FastPath, the virtual network gateway must be either:

Ultra Performance

You need to restrict traffic from VMScaleSet1 to VMScaleSet2. The solution must meet the virtual networking requirements.

What is the minimum number of custom NSG rules and NSG assignments required? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

To restrict traffic from VMScaleSet1 to VMScaleSet2, Network Security Group (NSG) rules need to be created and assigned to the appropriate resources. An NSG rule is required to allow or deny traffic to or from a network interface (NIC), VM, or subnet.

Based on the requirement to only allow traffic from VMScaleSet1 to VMScaleSet2 on TCP port 443, the following can be determined:

Minimum number of custom NSG rules:

You need at least one rule to allow TCP port 443 and another to deny all other traffic that does not match any prior rules. However, because NSGs have default rules that deny all inbound traffic if no other rule allows it, you might only need to create a single rule to allow traffic on TCP port 443. But to be fully explicit and depending on the existing rules, you might also add a deny rule explicitly. So, the minimum number could be 1 (if relying on default rules) or 2 (if being explicit).

Minimum number of NSG assignments:

For NSG assignments, you would typically assign an NSG to the subnet or network interfaces of VMScaleSet2 to control the inbound traffic from VMScaleSet1. Since all VM instances in a scale set can share a single NSG, you only need to make one assignment of the NSG to cover all instances of VMScaleSet2. Therefore, the minimum number of NSG assignments is 1.

So, for the given scenario:

The minimum number of custom NSG rules required: 1 (to allow TCP port 443, assuming default rules handle the deny)

The minimum number of NSG assignments required: 1 (assign the NSG to the subnet or NICs of VMScaleSet2)

These selections are made with the assumption that the goal is to enforce the minimum necessary configuration changes while still satisfying the requirements.

You create NSG10 and NSG11 to meet the network security requirements.

For each of the following statements, select Yes it the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

From VM1, you can establish a Remote Desktop session with VM2:

If NSG10 is associated with Subnet1 where VM1 is located, and there is a rule that allows outbound RDP traffic (typically TCP port 3389), then VM1 should be able to initiate an RDP session with VM2. Without a specific rule blocking RDP, the answer would typically be Yes.

From VM2, you can ping VM1:

ICMP traffic (which is used by the ping command) is usually blocked by default on NSGs unless a specific rule is created to allow it. If the firewall on the VMs allows ICMP traffic, but there is no NSG rule permitting ICMP, then VM2 would not be able to ping VM1. Unless NSG11 explicitly allows ICMP traffic outbound from VM2, the answer would be No.

From VM2, you can establish a Remote Desktop session with VM1:

This would depend on whether NSG11 allows outbound RDP traffic and NSG10 allows inbound RDP traffic. If NSG10 and NSG11 are configured with the custom rules you provided, which we don’t have the specifics of, and assuming that the NSG11 does not have a rule that blocks outbound RDP traffic and NSG10 allows inbound RDP, then the answer would be Yes.

Which virtual machines can VM1 and VM4 ping successfully? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: VM2, VM3 and VM4.

VM1 is in VNet1/Subnet1. VNet1 is peered with VNet2 and VNet3.

There are no NSGs blocking outbound ICMP from VNet1. There are no NSGs blocking inbound ICMP to VNet1/Subnet2, VNet2 or VNet3. Therefore, VM1 can ping VM2 in VNet1/Subnet2, VM3 in VNet2 and VM4 in VNet3.

Box 2:

VM4 is in VNet3. VNet3 is peered with VNet1 and VNet2. There are no NSGs blocking outbound ICMP from VNet3. There are no NSGs blocking inbound ICMP to VNet1/Subnet1, VNet1/Subnet2 or VNet2 from VNet3 (NSG10 blocks inbound ICMP from VNet4 but not from VNet3). Therefore, VM4 can ping VM1 in VNet1/Subnet1, VM2 in VNet1/Subnet2 and VM3 in VNet2.

Box 2: Yes

VM4 is in VNet3. Zone1.contoso.com has a link to VNet3 and auto-registration is enabled on the link.

Box3: No

VNet3 is linked to zone1.contoso.com and auto-registration is enabled on the link. A virtual network can only have one registration zone. You can link zone2.contoso.com to VNet3 but you won’t be able to enable auto-registration on the link.

You need to connect an on-premises network and an Azure environment. The solution must use ExpressRoute and support failing over to a Site-to-Site VPN connection if there is an ExpressRoute failure.

What should you configure? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

To connect an on-premises network to an Azure environment with a solution that uses ExpressRoute and supports failover to a Site-to-Site VPN connection in case of an ExpressRoute failure, you should use the following configurations:

Routing type:

For supporting both ExpressRoute and Site-to-Site VPN, you would use a Route-based VPN type. Policy-based VPNs do not support the dynamic routing that is necessary for ExpressRoute and VPN failover scenarios.

Number of virtual network gateways:

You would typically need 2 virtual network gateways for this scenario: one for the ExpressRoute connection and another for the Site-to-Site VPN connection. Azure supports the coexistence of ExpressRoute and Site-to-Site VPN connections, allowing you to configure them for high-availability scenarios. Each type of connection requires a separate gateway.

Therefore, the appropriate options are "Route-based" for the routing type and "2" for the number of virtual network gateways.

Which three actions should you perform in sequence before you can integrate WebApp1 and Vnet1? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

To integrate WebApp1 with Vnet1, the following actions need to be performed in sequence:

Modify the address space of Vnet1:

The address space for Vnet1 currently is 10.3.0.0/16, and the subnet also has the same address range which leaves no room for further subnetting. You would need to create a smaller subnet within this address space for the integration with WebApp1.

Create a service endpoint:

Service endpoints are needed to secure your critical Azure service resources to only your virtual networks. By enabling a service endpoint, traffic from your VNet to the Azure service always remains on the Microsoft Azure backbone network.

Add a private endpoint:

A private endpoint is a network interface that connects you privately and securely to a service powered by Azure Private Link. The private endpoint uses an IP address from your VNet, effectively bringing the service into your VNet.

These actions would enable private connectivity between WebApp1 and Vnet1, ensuring that the traffic between your web app and the virtual network is kept on the Azure backbone network, secure from the public internet.

You have an Azure subscription that is linked to an Azure Active Directory (Azure AD) tenant named contoso.onmicrosoft.com.

For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Based on the information provided in the screenshots regarding Azure App Service and its VNet Integration and Private Endpoint connections, let’s address the statements provided:

Subnet2 can contain only App Service apps in the ASP1 App Service plan.

No, this statement is not necessarily true. A subnet can contain multiple app services from different App Service plans, not just a single one like ASP1. The App Service plan determines the location, features, cost, and compute resources associated with an app, but multiple plans can use the same subnet for integration.

As12 will use an IP address from Subnet2 for network communications.

Yes, if the Azure App Service ‘as12’ is integrated with a VNet that includes Subnet2, it will use an IP address from Subnet2’s range for network communications within that VNet.

Computers in Vnet1 will connect to a private IP address when they connect to as12.

No, the screenshots do not show any configured private endpoint connections for the ‘as12’ app service, which would be required for ‘as12’ to have a private IP address within the VNet. Without a private endpoint, computers in Vnet1 would connect to the public IP address of ‘as12’, unless further configuration is done outside of what is shown in the screenshots.

You need to configure a Traffic Manager profile that will minimize the impact of DNS caching.

What should you configure? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

To minimize the impact of DNS caching when using Azure Traffic Manager with an application that connects to the first available endpoint from a list of endpoints, you should configure the Traffic Manager profile as follows:

Traffic Manager algorithm:

Priority: This routing method allows you to prioritize traffic to a particular endpoint over others. It ensures that all requests are sent to the highest-priority (primary) endpoint if it is available. If the primary endpoint is not available, Traffic Manager routes traffic to the next highest-priority endpoint. This setup minimizes the impact of DNS caching by always directing clients to the same endpoint, as long as it is available.

Endpoint type:

Azure endpoint: Since the web service instances are hosted in Azure and are accessible through public endpoints, you will use the Azure endpoint type for Traffic Manager.

These settings will direct App1 to consistently connect to the same endpoint (the one with the highest priority), assuming it is available, which is the desired behavior to minimize the impact of DNS caching. Traffic Manager will automatically failover to the next available endpoint based on the priority order defined, should the highest-priority endpoint become unavailable.

You have an Azure subscription.

You have the on-premises sites shown the following table.

You plan to deploy Azure Virtual WAN.

You are evaluating Virtual WAN Basic and Virtual WAN Standard.

Which type of Virtual WAN can you use for each site? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Azure Virtual WAN offers a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface. It supports various connection types like Site-to-Site VPN, Point-to-Site VPN, and ExpressRoute connections. Depending on the Virtual WAN tier (Basic or Standard), certain functionalities and connection types are supported.

Virtual WAN Basic typically supports basic VPN features and connectivity.

Virtual WAN Standard provides all the features of Basic, plus it supports ExpressRoute, Point-to-Site (P2S) VPN, and much more advanced features like VPN and ER connectivity, BGP routing, multiple connections, and custom BGP settings.

Given this:

Site1 with 500 users connected via ExpressRoute would require Virtual WAN Standard because Basic does not support ExpressRoute connections.

Site2 with 100 users connected via Site-to-Site VPN could be supported by either Virtual WAN Basic or Standard, as both support Site-to-Site VPN connections. However, considering the number of users and potential need for advanced features, Virtual WAN Standard might be more appropriate.

Site3 with 1 user connected via Point-to-Site VPN would typically only require Virtual WAN Basic, as it’s a single user and Basic supports P2S VPN. However, if advanced features of P2S VPN are required, such as Azure AD authentication, then Virtual WAN Standard would be necessary.

Based on these considerations, here are the selections:

Virtual WAN Basic: Can be used for Site2 and Site3 only.

Virtual WAN Standard: Can be used for Site1, Site2, and Site3.

The selection depends on the specific features and scalability requirements of each site’s connection to Azure. If the only consideration is the type of connectivity, then Basic could suffice for Site2 and Site3, while Standard is required for Site1. However, if advanced features are a consideration, Standard may be the appropriate choice across all sites.

You have an Azure subscription that contains two virtual networks named Vnet1 and Vnet2.

You register a public DNS zone named fabrikam.com.

The zone is configured as shown in the Public DNS Zone exhibit.

You have a private DNS zone named fabrikam.com.

The zone is configured as shown in the Private DNS Zone exhibit.

You have a virtual network link configured as shown in the Virtual Network Link exhibit.

For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: Yes

DNS queries from the internet use the public DNS zone. In the public DNS zone, www.fabrikam.com is a CNAME record that resolves to appservice1.fabrikam.com which resolves to 131.107.1.1.

Box 2: No

DNS queries from the internet use the public DNS zone. There is no DNS record for server1.fabrikam.com in the public DNS zone.

Box 3: No

The private DNS zone is linked to VNet1, not VNet2. Therefore, resources in VNet2 cannot query the private DNS zone.
