Show Answer
Correct Answer: VM1: VM2, VM3, and VM4 only VM4: VM1, VM2, and VM3 only
Explanation:
Before NSG10/NSG11 are created, only the existing NSGs apply, with default AllowVNetInBound/OutBound rules and a custom RDP allow. ICMP is allowed by the guest firewall. VNet1 is peered with VNet2 and VNet3, and VNet3 is peered with VNet1 and VNet2, so peered VNets can communicate. VNet4 is not peered with VNet1 or VNet3, so VM5 is unreachable.

Question 145

HOTSPOT - You have an Azure subscription that contains the resources shown in the following table. You establish BGP peering between NVA1 and Hub1. You need to implement transit connectivity between VNet1 and VNet3 via Hub1 by using BGP peering. The solution must minimize costs. What should you do? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Illustration for AZ-700 question 145 Illustration for AZ-700 question 145
Show Answer
Correct Answer: On Hub1: The defaultRouteTable and associate the routes with the defaultRouteTable On VNet3: User-defined routes
Explanation:
For Virtual WAN BGP transit with minimal cost, use the hub's default route table for propagation/association and configure UDRs on the spoke VNet that reaches the NVA. This avoids deploying additional gateway or Route Server resources.

Question 146

DRAG DROP - You have an Azure subscription that contains an Azure Firewall Premium policy named FWP1. To FWP1, you plan to add the rule collections shown in the following table. Which priority should you assign to each rule collection? To answer, drag the appropriate priority values to the correct rule collections. Each value 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.

Illustration for AZ-700 question 146 Illustration for AZ-700 question 146
Show Answer
Correct Answer: RC1: 200 RC2: 300 RC3: 100
Explanation:
Azure Firewall processes rule types in the order DNAT, then Network, then Application. Therefore assign the highest precedence (lowest number) to DNAT, followed by Network, then Application.

Question 148

DRAG DROP - 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.

Illustration for AZ-700 question 148
Show Answer
Correct Answer: SKU: Premium Block malicious bots: A managed rule Throttle client IP addresses: A custom rule
Explanation:
Bot protection in Azure Front Door WAF uses the managed Bot Manager rule set, which requires the Premium SKU. Rate limiting (for example, 100 requests/connections per minute per client IP) is implemented with a custom WAF rate-limit rule.

Question 150

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:
An internal Azure Load Balancer is deployed into a subnet and is assigned a private frontend IP address from that subnet. Azure Virtual Network NAT is associated with a subnet but does not consume an IP address in it. Service endpoint policies are policy objects and do not require subnet IPs. Virtual network peering connects VNets and does not allocate IP addresses in subnets.

Question 151

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:
A private endpoint is required to access an Azure Storage account privately from an on-premises network over a Site-to-Site VPN. Service endpoints apply to Azure virtual network subnets and do not by themselves provide on-premises access over VPN; Microsoft recommends Private Link/private endpoints for private connectivity from on-premises. An application gateway and a Private Link service are not appropriate for exposing an Azure Storage account.

Question 152

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.

Illustration for AZ-700 question 152 Illustration for AZ-700 question 152
Show Answer
Correct Answer: To allow inbound connections: A network rule To block outbound connections: An application rule
Explanation:
Network rules filter L3/L4 traffic by IP, port, and protocol. Application rules support FQDN-based filtering, making them appropriate for blocking *.fabrikam.com outbound.

Question 153

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 by the Ultra Performance and ErGw3AZ gateway SKUs. The requirement to minimize downtime if a single Azure datacenter fails requires a zone-redundant gateway (AZ SKU). Ultra Performance is not zone-redundant, while ErGw3AZ is zone-redundant and supports FastPath. ErGw1AZ and ErGw2AZ do not support FastPath.

Question 154

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.

Illustration for AZ-700 question 154
Show Answer
Correct Answer: Common header: X-Forwarded-For Header value: add_x_forwarded_for_proxy
Explanation:
To remove the client port from the forwarded header, rewrite the X-Forwarded-For header using the add_x_forwarded_for_proxy server variable, which preserves only the IP address information.

Question 155

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.

Illustration for AZ-700 question 155
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 to the Front Door endpoint and a TXT record for domain validation when using a third-party DNS provider. A customer-managed TLS certificate for Front Door is stored in Azure Key Vault.
