Question 650 A build pipeline assigns the same private address to two independent NICs. What is the most appropriate next design decision? Public IP Prefix for contiguous outbound allocation Private IP allocation consistency across NICs Static private NIC IP configuration NIC-level public IP association Explanation Correct Answer B:Private IP allocation consistency across NICs ensures private addresses belong to the selected subnet and interface configuration. Incorrect Answers A:That approach reserves a managed contiguous block of standard public addresses for public IP resources; it does not replace Private IP allocation consistency across NICs for the constraint in this scenario. C:Static private NIC IP configuration is useful when the goal is to assign an intended stable private address to a VM network interface within its subnet. Here, the required behavior is to ensure private addresses belong to the selected subnet and interface configuration. D:Although NIC-level public IP association attaches the public IP to the correct network interface IP configuration, that is not sufficient to ensure private addresses belong to the selected subnet and interface configuration in this case.
Question 651 A marketing website needs reduced latency for static assets without new regional servers. What is the most appropriate next design decision? Front Door custom domain binding Front Door caching configuration Azure Front Door global application delivery Front Door WAF policy association Explanation Correct Answer B:This choice caches eligible static web responses at the global edge under explicit policy. Incorrect Answers A:This alternative configures an approved domain, DNS validation and certificate for the edge endpoint, which solves a different networking task. It does not directly cache eligible static web responses at the global edge under explicit policy. C:This choice provides globally distributed edge entry points with accelerated HTTP/S routing to origins. It leaves the specific need to cache eligible static web responses at the global edge under explicit policy unaddressed. D:Although Front Door WAF policy association applies supported application-layer rules at the globally distributed edge, that is not sufficient to cache eligible static web responses at the global edge under explicit policy in this case.
Question 652 The incident response team must change a tuned WAF from detection to blocking. Which configuration should the team verify or implement first? WAF policy association to listener or domain WAF diagnostic logging and investigation WAF prevention mode for active blocking WAF on Application Gateway for regional web protection Explanation Correct Answer C:The intended behavior is to block HTTP requests that match configured WAF enforcement rules. WAF prevention mode for active blocking is the direct configuration or deployment choice. Incorrect Answers A: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 block HTTP requests that match configured WAF enforcement rules in this case. B:WAF diagnostic logging and investigation is useful when the goal is to correlate WAF rule IDs, policy actions and client requests to investigate web filtering. Here, the required behavior is to block HTTP requests that match configured WAF enforcement rules. D:WAF on Application Gateway for regional web protection inspects HTTP/S requests at a regional application gateway using supported WAF policies. The current problem instead requires a control that blocks HTTP requests that match configured WAF enforcement rules.
Question 653 A site recycles app workers and must exclude them until the health check responds. What should the administrator change or deploy? Application Gateway TLS termination Application Gateway URL rewrite rule Application Gateway custom health probe Application Gateway path-based routing rule Explanation Correct Answer C:Application Gateway custom health probe checks an application-specific path and expected response before including backends. Incorrect Answers A:Application Gateway TLS termination terminates client HTTPS on the gateway with the appropriate certificate and listener. The current problem instead requires a control that checks an application-specific path and expected response before including backends. B:Application Gateway URL rewrite rule is useful when the goal is to modify a supported request or response header or URL before upstream routing. Here, the required behavior is to check an application-specific path and expected response before including backends. D:Although Application Gateway path-based routing rule selects different backends based on URL path patterns, that is not sufficient to check an application-specific path and expected response before including backends in this case.
Question 654 BGP local preference changes must be tested before a primary link maintenance window. What is the most appropriate next design decision? ExpressRoute Global Reach ExpressRoute private peering ExpressRoute provider failover testing ExpressRoute peering and connection diagnostics Explanation Correct Answer C:ExpressRoute provider failover testing is appropriate because it validates routing and application failover across configured independent ExpressRoute paths. Incorrect Answers A:ExpressRoute Global Reach connects on-premises sites via their ExpressRoute circuits through provider-enabled private connectivity. The current problem instead requires a control that validates routing and application failover across configured independent ExpressRoute paths. B:That approach provides private routing to VNet private address spaces over an ExpressRoute circuit; it does not replace ExpressRoute provider failover testing for the constraint in this scenario. D:This alternative checks provider provisioning, BGP state and Azure connection health before making changes, which solves a different networking task. It does not directly validate routing and application failover across configured independent ExpressRoute paths.
Question 655 A regulated design requires all Azure firewall egress to transit the corporate inspection perimeter. Which choice matches the specific technical condition? Secure Virtual WAN hub with Azure Firewall Azure Firewall Basic for simple network filtering Azure Firewall DNAT rule Firewall forced tunneling via approved next hop Explanation Correct Answer D:The relevant action is Firewall forced tunneling via approved next hop: it routes Azure Firewall Internet-bound traffic toward another approved security device or on-premises edge. Incorrect Answers A:Secure Virtual WAN hub with Azure Firewall deploys Azure Firewall into a supported Virtual WAN virtual hub for managed inspection. The current problem instead requires a control that routes Azure Firewall Internet-bound traffic toward another approved security device or on-premises edge. B:Azure Firewall Basic for simple network filtering is useful when the goal is to fit eligible smaller workloads when advanced throughput and security features are not required. Here, the required behavior is to route Azure Firewall Internet-bound traffic toward another approved security device or on-premises edge. C:Azure Firewall DNAT rule is useful when the goal is to translate an approved public destination address and port to a protected internal service. Here, the required behavior is to route Azure Firewall Internet-bound traffic toward another approved security device or on-premises edge.
Question 656 A migration moves workloads to another endpoint-enabled subnet but the approved storage service endpoint policy remains bound only to the old subnet. Which configuration should the team verify or implement first? PaaS resource firewall VNet rule Service endpoint policy subnet binding Service endpoint unsupported-service review Service endpoint policy for storage resource scope Explanation Correct Answer B:The intended behavior is to associate an approved service endpoint policy with the intended endpoint-enabled workload subnet. Service endpoint policy subnet binding is the direct configuration or deployment choice. Incorrect Answers A:This choice permits the specified subnet at the target managed service after a service endpoint is enabled. It leaves the specific need to associate an approved service endpoint policy with the intended endpoint-enabled workload subnet unaddressed. C:That approach verifies whether the selected PaaS resource type supports service endpoints before planning access; it does not replace Service endpoint policy subnet binding for the constraint in this scenario. D:Service endpoint policy for storage resource scope restricts supported endpoint traffic from a subnet to specifically allowed Azure Storage resources. The current problem instead requires a control that associates an approved service endpoint policy with the intended endpoint-enabled workload subnet.
Question 657 A deployment fails because the specified subnet is unavailable to the endpoint. Which configuration addresses the stated network constraint? Private DNS zone group on private endpoint Private Endpoint subresource selection Private Endpoint for PaaS private IP access Private Endpoint subnet placement Explanation Correct Answer D:Private Endpoint subnet placement deploys a supported private endpoint NIC in the correct consumer VNet subnet. Incorrect Answers A:Private DNS zone group on private endpoint is useful when the goal is to integrate an endpoint with the appropriate private DNS zone records where supported. Here, the required behavior is to deploy a supported private endpoint NIC in the correct consumer VNet subnet. B:Although Private Endpoint subresource selection targets the correct service resource and subresource in a private endpoint connection, that is not sufficient to deploy a supported private endpoint NIC in the correct consumer VNet subnet in this case. C:Although Private Endpoint for PaaS private IP access exposes a supported Azure service through a private IP interface in the consumer VNet, that is not sufficient to deploy a supported private endpoint NIC in the correct consumer VNet subnet in this case.
Question 658 A network design needs Gateway Load Balancer instead of application-layer proxying. Which change should the network engineer make? Gateway Load Balancer for transparent NVA insertion Load Balancer backend pool membership Load Balancer HA ports Load Balancer outbound rule Explanation Correct Answer A:The relevant action is Gateway Load Balancer for transparent NVA insertion: it inserts a supported third-party network virtual appliance fleet transparently into traffic paths. Incorrect Answers B:Load Balancer backend pool membership is useful when the goal is to select the intended backend network interfaces or IPs that receive distributed traffic. Here, the required behavior is to insert a supported third-party network virtual appliance fleet transparently into traffic paths. C:Load Balancer HA ports enables a supported internal load balancer to handle a range of all TCP and UDP ports for NVA scenarios. The current problem instead requires a control that inserts a supported third-party network virtual appliance fleet transparently into traffic paths. D:Load Balancer outbound rule controls SNAT for backend VMs that require outbound connectivity using a load-balancer frontend. The current problem instead requires a control that inserts a supported third-party network virtual appliance fleet transparently into traffic paths.
Question 659 A global business needs DNS-level failover between regional websites. What action most directly addresses the documented failure? Azure Traffic Manager DNS routing Regional Azure Load Balancer for L4 traffic Load Balancer load-balancing rule Traffic Manager endpoint health monitoring Explanation Correct Answer A:Azure Traffic Manager DNS routing chooses between geographically distributed public endpoints through DNS responses. Incorrect Answers B:Regional Azure Load Balancer for L4 traffic distributes TCP or UDP flows to healthy backend instances in an Azure region. The current problem instead requires a control that chooses between geographically distributed public endpoints through DNS responses. C:This choice defines a frontend protocol/port and backend pool mapping for distributed connections. It leaves the specific need to choose between geographically distributed public endpoints through DNS responses unaddressed. D:This alternative uses endpoint status probes to determine which DNS endpoints remain eligible, which solves a different networking task. It does not directly choose between geographically distributed public endpoints through DNS responses.
Question 660 A legacy backend needs a URL prefix rewritten without changing application code. Which approach best satisfies the access or connectivity requirement? Application Gateway path-based routing rule Application Gateway custom health probe Application Gateway URL rewrite rule Application Gateway for regional HTTP routing Explanation Correct Answer C:The relevant action is Application Gateway URL rewrite rule: it modifies a supported request or response header or URL before upstream routing. Incorrect Answers A:This choice selects different backends based on URL path patterns. It leaves the specific need to modify a supported request or response header or URL before upstream routing unaddressed. B:Application Gateway custom health probe checks an application-specific path and expected response before including backends. The current problem instead requires a control that modifies a supported request or response header or URL before upstream routing. D: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 modify a supported request or response header or URL before upstream routing.
