Question 380 One subnet can reach a storage account while another endpoint-enabled subnet cannot. Which change should the network engineer make? Service endpoint unsupported-service review PaaS resource firewall VNet rule Service endpoint public address distinction Service endpoint diagnostic separation Explanation Correct Answer D:Service endpoint diagnostic separation is appropriate because it checks source subnet configuration, resource firewall rules and actual service reachability. Incorrect Answers A:Although Service endpoint unsupported-service review verifies whether the selected PaaS resource type supports service endpoints before planning access, that is not sufficient to check source subnet configuration, resource firewall rules and actual service reachability in this case. B:This alternative permits the specified subnet at the target managed service after a service endpoint is enabled, which solves a different networking task. It does not directly check source subnet configuration, resource firewall rules and actual service reachability. C:This alternative retains public service endpoint addressing while changing private subnet routing and service firewall identity, which solves a different networking task. It does not directly check source subnet configuration, resource firewall rules and actual service reachability.
Question 381 A DNS appliance changes its private NIC address after maintenance and peers fail. What is the most appropriate next design decision? Private IP allocation consistency across NICs Static private NIC IP configuration Subnet network policy placement NIC-level public IP association Explanation Correct Answer B:The intended behavior is to assign an intended stable private address to a VM network interface within its subnet. Static private NIC IP configuration is the direct configuration or deployment choice. Incorrect Answers A:Although Private IP allocation consistency across NICs ensures private addresses belong to the selected subnet and interface configuration, that is not sufficient to assign an intended stable private address to a VM network interface within its subnet in this case. C:Although Subnet network policy placement places security and routing policies on the workload subnet rather than assuming a public IP defines security, that is not sufficient to assign an intended stable private address to a VM network interface within its subnet in this case. D:NIC-level public IP association attaches the public IP to the correct network interface IP configuration. The current problem instead requires a control that assigns an intended stable private address to a VM network interface within its subnet.
Question 382 A SQL private endpoint connection succeeds by IP but the service FQDN resolves incorrectly. Which implementation most directly resolves this requirement? Azure DNS Private Resolver inbound endpoint Azure DNS Private Resolver outbound endpoint Private DNS zone VNet link DNS private endpoint record validation Explanation Correct Answer D:DNS private endpoint record validation is appropriate because it confirms private service FQDNs resolve to the intended private endpoint addresses. Incorrect Answers A:This alternative accepts DNS queries arriving from on-premises or connected networks into Azure resolution, which solves a different networking task. It does not directly confirm private service FQDNs resolve to the intended private endpoint addresses. B:This choice sends selected Azure DNS queries toward other DNS servers through managed forwarding. It leaves the specific need to confirm private service FQDNs resolve to the intended private endpoint addresses unaddressed. C:That approach permits a selected VNet's resolver to query records in a private DNS zone; it does not replace DNS private endpoint record validation for the constraint in this scenario.
Question 383 A service endpoint-enabled VM still gets an authorization denial from Azure Storage. What should the team implement or correct? PaaS resource firewall VNet rule VNet service endpoint enablement Service endpoint public address distinction Service endpoint diagnostic separation Explanation Correct Answer D:The relevant action is Service endpoint diagnostic separation: it checks source subnet configuration, resource firewall rules and actual service reachability. Incorrect Answers A:PaaS resource firewall VNet rule permits the specified subnet at the target managed service after a service endpoint is enabled. The current problem instead requires a control that checks source subnet configuration, resource firewall rules and actual service reachability. B:This alternative extends selected Azure service routing and service identity from an approved VNet subnet, which solves a different networking task. It does not directly check source subnet configuration, resource firewall rules and actual service reachability. C:This alternative retains public service endpoint addressing while changing private subnet routing and service firewall identity, which solves a different networking task. It does not directly check source subnet configuration, resource firewall rules and actual service reachability.
Question 384 A new internet gateway requires public IP resources that match its zone-resilient design. Which network component or setting is the best fit? NIC-level public IP association Subnet network policy placement Public IP SKU and zone suitability Standard Public IP for internet-facing VM Explanation Correct Answer C:This choice selects the supported public IP SKU and zone behavior for the intended resource and region. Incorrect Answers A:NIC-level public IP association attaches the public IP to the correct network interface IP configuration. The current problem instead requires a control that selects the supported public IP SKU and zone behavior for the intended resource and region. B:This alternative places security and routing policies on the workload subnet rather than assuming a public IP defines security, which solves a different networking task. It does not directly select the supported public IP SKU and zone behavior for the intended resource and region. D:This alternative assigns a routable public endpoint to a specified Azure resource when direct exposure is justified, which solves a different networking task. It does not directly select the supported public IP SKU and zone behavior for the intended resource and region.
Question 385 New subnets need room without colliding with peered or on-premises ranges. Which choice matches the specific technical condition? Address-prefix growth and readdress planning Nonoverlapping VNet CIDR planning Static private NIC IP configuration Custom IP Prefix for bring-your-own-IP Explanation Correct Answer A:The intended behavior is to expand address capacity while managing dependencies and routing effects. Address-prefix growth and readdress planning is the direct configuration or deployment choice. Incorrect Answers B:This alternative prevents address collisions between Azure networks and corporate routes, which solves a different networking task. It does not directly expand address capacity while managing dependencies and routing effects. C:That approach assigns an intended stable private address to a VM network interface within its subnet; it does not replace Address-prefix growth and readdress planning for the constraint in this scenario. D:Custom IP Prefix for bring-your-own-IP is useful when the goal is to onboard an organization's eligible public IPv4 address block into Azure. Here, the required behavior is to expand address capacity while managing dependencies and routing effects.
Question 386 A security change has no effect because an earlier matching rule is used. Which network component or setting is the best fit? NSG rule priority and first-match evaluation Azure Virtual Network Manager security admin policy NSG network interface association IP flow verify for NSG traffic decision Explanation Correct Answer A:This choice ensures a more specific permitted or denied flow is evaluated in the intended priority order. Incorrect Answers B:Although Azure Virtual Network Manager security admin policy governs supported high-priority security admin rules across centrally managed VNets, that is not sufficient to ensure a more specific permitted or denied flow is evaluated in the intended priority order in this case. C:NSG network interface association applies additional instance-specific NSG rules to a selected network interface. The current problem instead requires a control that ensures a more specific permitted or denied flow is evaluated in the intended priority order. D:This alternative tests a specified source/destination/port and reports the allowing or blocking NSG rule, which solves a different networking task. It does not directly ensure a more specific permitted or denied flow is evaluated in the intended priority order.
Question 387 A regional deployment consolidates separate FQDN websites behind one Application Gateway. What action most directly addresses the documented failure? Application Gateway HTTP settings Application Gateway path-based routing rule Application Gateway multi-site routing Application Gateway HTTP listener Explanation Correct Answer C:Application Gateway multi-site routing uses host-based listeners to select application backends for different domain names. Incorrect Answers A:Application Gateway HTTP settings is useful when the goal is to configure supported backend protocol, port, host-name and session behavior. Here, the required behavior is to use host-based listeners to select application backends for different domain names. B:This alternative selects different backends based on URL path patterns, which solves a different networking task. It does not directly use host-based listeners to select application backends for different domain names. D:Although Application Gateway HTTP listener matches incoming protocol, port and optional host name before routing requests, that is not sufficient to use host-based listeners to select application backends for different domain names in this case.
Question 388 A service must provision several stable public IPs from one predictable block. Which network component or setting is the best fit? NIC-level public IP association Standard Public IP for internet-facing VM Public IP Prefix for contiguous outbound allocation Subnet network policy placement Explanation Correct Answer C:This choice reserves a managed contiguous block of standard public addresses for public IP resources. Incorrect Answers A:That approach attaches the public IP to the correct network interface IP configuration; it does not replace Public IP Prefix for contiguous outbound allocation for the constraint in this scenario. B:This choice assigns a routable public endpoint to a specified Azure resource when direct exposure is justified. It leaves the specific need to reserve a managed contiguous block of standard public addresses for public IP resources unaddressed. D:This alternative places security and routing policies on the workload subnet rather than assuming a public IP defines security, which solves a different networking task. It does not directly reserve a managed contiguous block of standard public addresses for public IP resources.
Question 389 An internet-egress service needs managed outbound SNAT without giving each VM a public IP. Which Azure control would meet the operational need? NAT Gateway subnet association NAT Gateway public IP allocation Private DNS zone access for peered VNets NAT Gateway for predictable outbound SNAT Explanation Correct Answer D:The intended behavior is to provide scalable managed outbound connectivity for private subnet workloads. NAT Gateway for predictable outbound SNAT is the direct configuration or deployment choice. Incorrect Answers A:This alternative applies a NAT Gateway's outbound SNAT behavior to a selected subnet, which solves a different networking task. It does not directly provide scalable managed outbound connectivity for private subnet workloads. B:That approach assigns supported public IP or public IP prefix resources to the gateway; it does not replace NAT Gateway for predictable outbound SNAT for the constraint in this scenario. C:This alternative links the private DNS zone to the VNet where clients need its records rather than assuming VNet peering provides name resolution, which solves a different networking task. It does not directly provide scalable managed outbound connectivity for private subnet workloads.
Question 390 An application needs /static routed to cache nodes and /app to dynamic servers. Which network component or setting is the best fit? Application Gateway URL rewrite rule Application Gateway multi-site routing Application Gateway for regional HTTP routing Application Gateway path-based routing rule Explanation Correct Answer D:The intended behavior is to select different backends based on URL path patterns. Application Gateway path-based routing rule is the direct configuration or deployment choice. Incorrect Answers A: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 select different backends based on URL path patterns. B: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:This alternative provides managed regional Layer 7 routing, TLS termination and web traffic distribution, which solves a different networking task. It does not directly select different backends based on URL path patterns.
