Virtual WAN virtual hub creation Virtual WAN third-party NVA integration Virtual WAN secure hub with Azure Firewall Virtual WAN hub routing table association Explanation Correct Answer B:The relevant action is Virtual WAN third-party NVA integration: it deploys a supported third-party network virtual appliance in the managed hub solution. Incorrect Answers A:Although Virtual WAN virtual hub creation deploys a Microsoft-managed regional hub for connectivity, routing and gateway services, that is not sufficient to deploy a supported third-party network virtual appliance in the managed hub solution in this case. C:Although Virtual WAN secure hub with Azure Firewall integrates managed central security inspection into a Virtual WAN virtual hub, that is not sufficient to deploy a supported third-party network virtual appliance in the managed hub solution in this case. D:Although Virtual WAN hub routing table association controls which route table a hub connection uses for its forwarding decisions, that is not sufficient to deploy a supported third-party network virtual appliance in the managed hub solution in this case.
Question 821 The architect needs explicit lifecycle control of a VM's externally reachable address. Which configuration should the team verify or implement first? Static private NIC IP configuration Public IP SKU and zone suitability NIC-level public IP association Standard Public IP for internet-facing VM Explanation Correct Answer D:This choice assigns a routable public endpoint to a specified Azure resource when direct exposure is justified. Incorrect Answers A:This choice assigns an intended stable private address to a VM network interface within its subnet. It leaves the specific need to assign a routable public endpoint to a specified Azure resource when direct exposure is justified unaddressed. B:This choice selects the supported public IP SKU and zone behavior for the intended resource and region. It leaves the specific need to assign a routable public endpoint to a specified Azure resource when direct exposure is justified unaddressed. C:This alternative attaches the public IP to the correct network interface IP configuration, which solves a different networking task. It does not directly assign a routable public endpoint to a specified Azure resource when direct exposure is justified.
Question 822 A branch-to-Azure VPN is being designed with active-active gateway support. Which step best addresses this particular situation? BGP route advertisement on VPN Zone-redundant VPN Gateway Route-based site-to-site VPN gateway IPsec/IKE policy interoperability Explanation Correct Answer C:Route-based site-to-site VPN gateway is appropriate because it supports dynamic routing-based IPsec connectivity between Azure and a corporate VPN device. Incorrect Answers A:Although BGP route advertisement on VPN exchanges dynamic network prefixes over a supported route-based VPN configuration, that is not sufficient to support dynamic routing-based IPsec connectivity between Azure and a corporate VPN device in this case. B:Zone-redundant VPN Gateway is useful when the goal is to place a supported VPN gateway across availability zones for regional resilience. Here, the required behavior is to support dynamic routing-based IPsec connectivity between Azure and a corporate VPN device. D:Although IPsec/IKE policy interoperability aligns matching tunnel cryptographic parameters between Azure gateway and on-premises VPN device, that is not sufficient to support dynamic routing-based IPsec connectivity between Azure and a corporate VPN device in this case.
Question 823 A web gateway routes every request to the home page pool despite path requirements. What is the most appropriate next design decision? Application Gateway multi-site routing Application Gateway path-based routing rule Application Gateway for regional HTTP routing Application Gateway custom health probe Explanation Correct Answer B:This choice selects different backends based on URL path patterns. Incorrect Answers A:Although Application Gateway multi-site routing uses host-based listeners to select application backends for different domain names, that is not sufficient to select different backends based on URL path patterns in this case. C:Application Gateway for regional HTTP routing is useful when the goal is to provide managed regional Layer 7 routing, TLS termination and web traffic distribution. Here, the required behavior is to select different backends based on URL path patterns. D:This choice checks an application-specific path and expected response before including backends. It leaves the specific need to select different backends based on URL path patterns unaddressed.
Question 824 A workload moves private endpoints and its A records need validation before cutover. Which Azure control would meet the operational need? Private DNS zone VNet link Azure private DNS zone Azure DNS Private Resolver inbound endpoint DNS private endpoint record validation Explanation Correct Answer D:This choice confirms private service FQDNs resolve to the intended private endpoint addresses. Incorrect Answers A:This choice permits a selected VNet's resolver to query records in a private DNS zone. It leaves the specific need to confirm private service FQDNs resolve to the intended private endpoint addresses unaddressed. B:Azure private DNS zone stores DNS records visible through linked private-network resolution rather than public DNS. The current problem instead requires a control that confirms private service FQDNs resolve to the intended private endpoint addresses. C:That approach accepts DNS queries arriving from on-premises or connected networks into Azure resolution; it does not replace DNS private endpoint record validation for the constraint in this scenario.
Question 825 A new custom rule is evaluated by querying WAF diagnostic records. Which change should the network engineer make? WAF diagnostic logging and investigation WAF policy association to listener or domain WAF on Azure Front Door for global edge protection Managed WAF rule set selection Explanation Correct Answer A:This choice correlates WAF rule IDs, policy actions and client requests to investigate web filtering. Incorrect Answers B:Although WAF policy association to listener or domain binds the WAF policy to the supported application gateway listener or edge domain, that is not sufficient to correlate WAF rule IDs, policy actions and client requests to investigate web filtering in this case. C:WAF on Azure Front Door for global edge protection inspects web traffic at Microsoft's global edge before it reaches regional origins. The current problem instead requires a control that correlates WAF rule IDs, policy actions and client requests to investigate web filtering. D:Although Managed WAF rule set selection uses a supported managed web attack signature rule set for common application threats, that is not sufficient to correlate WAF rule IDs, policy actions and client requests to investigate web filtering in this case.
Question 826 An inspection service is integrated into another load balancer frontend using a gateway chaining model. Which configuration should the team verify or implement first? Load Balancer HA ports Regional Azure Load Balancer for L4 traffic Load Balancer backend pool membership Gateway Load Balancer for transparent NVA insertion Explanation Correct Answer D:This choice inserts a supported third-party network virtual appliance fleet transparently into traffic paths. Incorrect Answers A:This alternative enables a supported internal load balancer to handle a range of all TCP and UDP ports for NVA scenarios, which solves a different networking task. It does not directly insert a supported third-party network virtual appliance fleet transparently into traffic paths. B:Although Regional Azure Load Balancer for L4 traffic distributes TCP or UDP flows to healthy backend instances in an Azure region, that is not sufficient to insert a supported third-party network virtual appliance fleet transparently into traffic paths in this case. C:Load Balancer backend pool membership selects the intended backend network interfaces or IPs that receive distributed traffic. The current problem instead requires a control that inserts a supported third-party network virtual appliance fleet transparently into traffic paths.
Question 827 Only one of three VNets can resolve an on-premises zone through the shared resolver. What should the administrator change or deploy? Ruleset VNet association Private DNS zone VNet link DNS forwarding ruleset and rules Azure-provided DNS for VNet hostnames Explanation Correct Answer A:This choice links a forwarding ruleset to the VNets that need to use it. Incorrect Answers B:This alternative permits a selected VNet's resolver to query records in a private DNS zone, which solves a different networking task. It does not directly link a forwarding ruleset to the VNets that need to use it. C:DNS forwarding ruleset and rules is useful when the goal is to match a domain suffix and forwards queries to designated DNS target servers. Here, the required behavior is to link a forwarding ruleset to the VNets that need to use it. D:Azure-provided DNS for VNet hostnames is useful when the goal is to resolve supported internal hostnames using default Azure DNS within a VNet. Here, the required behavior is to link a forwarding ruleset to the VNets that need to use it.
Question 828 An engineer needs to move a public IP association to a replacement VM NIC during cutover. What should the team implement or correct? Static private NIC IP configuration Public IP SKU and zone suitability IP configuration for multiple VM addresses NIC-level public IP association Explanation Correct Answer D:This choice attaches the public IP to the correct network interface IP configuration. Incorrect Answers A:That approach assigns an intended stable private address to a VM network interface within its subnet; it does not replace NIC-level public IP association for the constraint in this scenario. B:That approach selects the supported public IP SKU and zone behavior for the intended resource and region; it does not replace NIC-level public IP association for the constraint in this scenario. C:This alternative uses multiple supported IP configurations on a network interface for distinct service addresses, which solves a different networking task. It does not directly attache the public IP to the correct network interface IP configuration.
Question 829 A Standard firewall deployment cannot meet a new IDPS and TLS-inspection requirement. Which choice matches the specific technical condition? Secure Virtual WAN hub with Azure Firewall Azure Firewall Premium for TLS inspection Firewall logs and threat intelligence monitoring Azure Firewall Basic for simple network filtering Explanation Correct Answer B:This choice uses the Premium tier's supported TLS inspection and advanced threat features. Incorrect Answers A:This choice deploys Azure Firewall into a supported Virtual WAN virtual hub for managed inspection. It leaves the specific need to use the Premium tier's supported TLS inspection and advanced threat features unaddressed. C:Although Firewall logs and threat intelligence monitoring uses firewall diagnostic events and threat intelligence signals to investigate blocked and allowed traffic, that is not sufficient to use the Premium tier's supported TLS inspection and advanced threat features in this case. D:This alternative fits eligible smaller workloads when advanced throughput and security features are not required, which solves a different networking task. It does not directly use the Premium tier's supported TLS inspection and advanced threat features.
Question 830 An engineer reviews port 3389 exposure on a sensitive VM's NSG. Which implementation most directly resolves this requirement? Azure Bastion for browser-based VM administration NSG outbound rule destination and port IP flow verify for NSG traffic decision NSG remote management least privilege Explanation Correct Answer D:NSG remote management least privilege is appropriate because it limits administrative connections to approved sources and ports rather than Internet-wide access. Incorrect Answers A:Although Azure Bastion for browser-based VM administration provides managed remote VM access without exposing RDP or SSH public IPs on each VM, that is not sufficient to limit administrative connections to approved sources and ports rather than Internet-wide access in this case. B:This alternative restricts workloads initiating network connections toward disallowed destinations, which solves a different networking task. It does not directly limit administrative connections to approved sources and ports rather than Internet-wide access. C:This choice tests a specified source/destination/port and reports the allowing or blocking NSG rule. It leaves the specific need to limit administrative connections to approved sources and ports rather than Internet-wide access unaddressed.
