You have an Azure subscription.
You plan to deploy Azure Front Door with Azure Web Application Firewall (WAF).
You plan to implement custom rules and managed rules that meet the following requirements:
• Block malicious bots.
• Throttle client IP addresses that exceed 100 connections per minute.
You need to identify which Front Door SKU to configure, and which type of rule to configure for each requirement. The solution must minimize administrative effort and costs.
What should you identify? To answer, drag the appropriate options to the correct targets. Each option may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: SKU: Premium
Block malicious bots: A managed rule
Throttle client IP addresses: A custom rule
Explanation: Azure Front Door Premium is required to use WAF managed rule sets that include bot protection. Blocking malicious bots is best handled by managed rules (Bot Manager). Throttling requests by client IP (rate limiting, e.g., 100 requests per minute) requires a custom WAF rule.
Question 147
You are planning the IP addressing for the subnets in Azure virtual networks.
Which type of resource requires IP addresses in the subnets?
A. Azure Virtual Network NAT
B. service endpoint policies
C. internal load balancers
D. virtual network peering
Show Answer
Correct Answer: C
Explanation: Internal load balancers require one or more private IP addresses that are allocated from the subnet in which the load balancer is deployed. The other options (Azure Virtual Network NAT, service endpoint policies, and virtual network peering) do not consume IP addresses from the subnet address space.
Question 148
You have an on-premises network named Site1.
You have an Azure subscription that contains a virtual network named VNet1 and a storage account named storage1.
Site1 and VNet1 are connected by using a Site-to-Site (S2S) VPN.
You need to ensure that the servers in Site1 can connect to storage1 by using the S2S VPN. The solution must minimize administrative effort.
What should you create on VNet1?
A. an Azure application gateway
B. an Azure Private Link service
C. a service endpoint
D. a private endpoint
Show Answer
Correct Answer: D
Explanation: To allow on-premises servers to access an Azure Storage account over an existing S2S VPN, the storage service must be reachable via a private IP in the virtual network. A private endpoint places a private IP for the storage account into VNet1, which is reachable from Site1 through the VPN with minimal ongoing administration. Service endpoints do not natively support on-premises access over VPN and require additional configuration and constraints, making them unsuitable here. Other options are unrelated to storage connectivity.
Question 149
HOTSPOT -
You have an Azure subscription that contains 10 virtual machines. The virtual machines are assigned private IP addresses. The subscription contains the resources shown in the following table.
You need to configure FWPolicy1 to meet the following requirements:
• Allow incoming connections to the virtual machines from the internet on port 4567.
• Block outbound connections from the virtual machines to an FQDN of *.fabrikam.com.
What should you configure in FWPolicy1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: To allow inbound connections:
A network rule
To block outbound connections:
An application rule
Explanation: Inbound internet traffic on a specific TCP port (4567) to multiple VMs/subnets is filtered at L3/L4, which is handled by a network rule (DNAT is only required when translating to a specific private IP).
Blocking traffic to an FQDN (*.fabrikam.com) requires L7 inspection, which is done with an application rule.
Question 150
You have an on-premises datacenter and an Azure subscription.
You plan to implement ExpressRoute FastPath.
You need to create an ExpressRoute gateway. The solution must minimize downtime if a single Azure datacenter fails.
Which SKU should you use?
A. ErGw1AZ
B. High performance
C. Ultra performance
D. ErGw3AZ
E. ErGw2AZ
Show Answer
Correct Answer: D
Explanation: ExpressRoute FastPath is supported only by the Ultra Performance gateway and the ErGw3AZ SKU. To minimize downtime if a single Azure datacenter fails, the gateway must be zone-redundant (AZ). Ultra Performance is not zone-redundant, while ErGw3AZ is zone-redundant and supports FastPath. Other AZ SKUs (ErGw1AZ, ErGw2AZ) do not support FastPath. Therefore, ErGw3AZ is the correct choice.
Question 151
HOTSPOT
-
You have an Azure application gateway.
You need to create a rewrite rule that will remove the origin port from the HTTP header of incoming requests that are being forwarded to the backend pool.
How should you configure each setting? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: Common header:
X-Forwarded-For
Header value:
add_x_forwarded_for_proxy
Explanation: Application Gateway adds the X-Forwarded-For header including client IP and port. Rewriting this header to the add_x_forwarded_for_proxy variable preserves only the client IP addresses and removes the port information before forwarding to the backend.
Question 152
HOTSPOT -
You have an Azure subscription that contains an Azure key vault named Vault1 and an app registration for an Azure AD app named App1.
You have a DNS domain named contoso.com that is hosted by a third-party DNS provider.
You plan to deploy App1 by using Azure App Service. App1 will have the following configurations:
• App1 will be hosted across five App Service apps.
• Users will access App1 by using a URL of https://app1.contoso.com.
• The user traffic of App1 will be managed by using Azure Front Door.
• The traffic between Front Door and the App Service apps will be sent by using HTTP.
• App1 will be secured by using an SSL certificate from a third-party certificate authority (CA).
You need to support the Front Door deployment.
Which two DNS records should you create, and to where should you import the SSL certificate for App1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: DNS records:
A CNAME record and a TXT record
Import the certificate to:
Vault1
Explanation: Azure Front Door custom domains require a CNAME record to map app1.contoso.com to the Front Door endpoint and a TXT record to verify domain ownership when using a third‑party DNS provider. When using a third‑party SSL certificate with Azure Front Door, the certificate must be imported into Azure Key Vault so Front Door can access it securely.
Question 153
HOTSPOT -
Your on-premises network contains a server named DNS1 that runs Windows Server 2022. DNS1 has the DNS server role and an IP address of 10.1.0.1. The network contains computers that use DNS1 for name resolution.
You have an Azure subscription that contains the resources shown in the following table.
The on-premises network connects to Vnet1 by using a Site-to-Site VPN.
You need to ensure that the computers on the on-premises network can resolve the IP address for sql1.private.fabrikam.com.
What should you do on DNS1 and DNS2? To answer, drag the appropriate actions to the correct servers. Each action may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Show Answer
Correct Answer: DNS1:
Configure forwarding to 10.100.0.1.
DNS2:
Configure forwarding to 168.63.129.16.
Explanation: DNS1 (on‑premises) must forward queries for the Azure Private DNS zone to a DNS server inside Azure (DNS2). DNS2, running in Azure, then forwards unresolved queries to the Azure recursive resolver (168.63.129.16), which can resolve records in the linked private DNS zone.
Question 154
You have an Azure subscription that contains a virtual network named VNet1. VNet1 has a subnet mask of/24.
You plan to implement an Azure application gateway that will have the following configurations:
• Public endpoints: 1
• Private endpoints: 1
• Minimum instances: 1
• Maximum instances: 10
You need to configure the address space for the subnet of the application gateway. The solution must minimize the number of IP addresses allocated to the application gateway subnet.
What is the minimum number of assignable IP addresses required?
A. 1
B. 2
C. 11
D. 12
E. 20
Show Answer
Correct Answer: C
Explanation: Azure Application Gateway consumes one private IP per instance and one additional private IP if a private frontend is configured. With a maximum of 10 instances and 1 private endpoint, that is 11 assignable IPs. The public endpoint uses a public IP resource and does not consume subnet IPs. Therefore, the minimum number of assignable IP addresses required is 11.
Question 155
You are planning the IP addressing for the subnets in Azure virtual networks.
Which type of resource requires IP addresses in the subnets?
A. internal load balancers
B. Azure DDoS Protection for virtual networks
C. service endpoint policies
D. service endpoints
Show Answer
Correct Answer: A
Explanation: Internal load balancers require one or more private IP addresses from the subnet to which they are deployed in order to receive and distribute traffic. Azure DDoS Protection is enabled at the virtual network level and does not consume subnet IPs. Service endpoint policies and service endpoints are configuration features applied to subnets and do not allocate or require dedicated IP addresses.
