Question 300
A globally distributed web service wants endpoint failover by changing the DNS answer based on health, not by proxying every HTTP request. A regional service fails but some users keep reaching it until cached DNS answers expire despite Traffic Manager reporting a healthy alternate. Which response best addresses these needs?
- Use a supported web delivery layer such as Front Door or Application Gateway for TLS and WAF inspection; review DNS caching and TTL behavior and design client retry expectations for Traffic Manager failover.
- Configure Azure Traffic Manager with an appropriate traffic-routing method and endpoint monitoring; review DNS caching and TTL behavior and design client retry expectations for Traffic Manager failover.
- Review DNS caching and TTL behavior and design client retry expectations for Traffic Manager failover; do not configure Azure Traffic Manager with an appropriate traffic-routing method and endpoint monitoring.
- Configure Azure Traffic Manager with an appropriate traffic-routing method and endpoint monitoring; use Traffic Manager weighted routing with monitored endpoints and validate the resulting DNS responses.
Explanation
Correct Answer
B:Traffic Manager makes DNS-level routing decisions and is not an inline application proxy. DNS-based failover cannot immediately replace a connection that relies on an already cached address. Both actions are needed.
Incorrect Answers
A:Traffic Manager makes DNS-level routing decisions and is not an inline application proxy.
C:This plan leaves out a required action: Configure Azure Traffic Manager with an appropriate traffic-routing method and endpoint monitoring. The remaining action alone does not satisfy the situation.
D:DNS-based failover cannot immediately replace a connection that relies on an already cached address.
Question 301
A worldwide retail site needs Microsoft edge-based HTTP routing, TLS termination, caching, and automatic origin health failover. An international website must route European and Asian requests across geographically dispersed origins while accelerating HTTPS delivery. A CDN-enabled app serves outdated pricing pages for hours after prices change in the origin database. What is the most appropriate plan for this situation?
- Deploy an appropriate Azure Front Door profile with routes, origin groups, endpoints, and health probes; configure Front Door rules sets and route options to apply the approved redirects and URL rewrites; and adjust Front Door caching behavior and implement a controlled purge or cache-bypass path for freshness-sensitive responses.
- Deploy an appropriate Azure Front Door profile with routes, origin groups, endpoints, and health probes; configure Front Door origin groups and routes with appropriate priority and latency-based traffic distribution; and adjust Front Door caching behavior and implement a controlled purge or cache-bypass path for freshness-sensitive responses.
- Configure Front Door rules sets and route options to apply the approved redirects and URL rewrites; configure Front Door origin groups and routes with appropriate priority and latency-based traffic distribution; and adjust Front Door caching behavior and implement a controlled purge or cache-bypass path for freshness-sensitive responses.
- Deploy an appropriate Azure Front Door profile with routes, origin groups, endpoints, and health probes; configure Front Door origin groups and routes with appropriate priority and latency-based traffic distribution; and configure Front Door rules sets and route options to apply the approved redirects and URL rewrites.
Explanation
Correct Answer
B:Front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing. Front Door's global edge and origin selection differ from Azure's regional Application Gateway footprint. Edge caching improves latency but requires invalidation and cache-control policies to avoid serving stale dynamic data. Each decision addresses a separate requirement.
Incorrect Answers
A:Two actions meet their requirements, but action 2 misses this need: front Door's global edge and origin selection differ from Azure's regional Application Gateway footprint.
C:Two actions meet their requirements, but action 1 misses this need: front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing.
D:Two actions meet their requirements, but action 3 misses this need: edge caching improves latency but requires invalidation and cache-control policies to avoid serving stale dynamic data.
Question 302
An operations team treats a service tag as a permanent list of Azure public CIDRs and manually pins stale values in every NSG. A VNet is configured with an alternate DNS server address, but the team attributes unrelated IP exhaustion to DNS settings. Which course of action addresses the stated issues?
- Use supported service tags where appropriate and review service scope instead of freezing changing platform address lists; investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration.
- Use supported service tags where appropriate and review service scope instead of freezing changing platform address lists; check supported global or cross-region load-balancing constructs and separate regional address identities where required.
- Investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration; do not use supported service tags where appropriate and review service scope instead of freezing changing platform address lists.
- Resolve the address overlap before deploying peering and hybrid route advertisements into the same connectivity topology; investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration.
Explanation
Correct Answer
A:Service tags abstract approved platform prefixes and reduce configuration drift from evolving Azure address ranges. Name resolution settings do not increase the number of assignable private addresses in a subnet. Both actions are needed.
Incorrect Answers
B:Name resolution settings do not increase the number of assignable private addresses in a subnet.
C:This plan leaves out a required action: Use supported service tags where appropriate and review service scope instead of freezing changing platform address lists. The remaining action alone does not satisfy the situation.
D:Service tags abstract approved platform prefixes and reduce configuration drift from evolving Azure address ranges.
Question 303
During an Azure networking rollout, the team must resolve both of these conditions. A company seeks lower latency by reducing gateway data-path processing for eligible ExpressRoute workloads. An ExpressRoute design relies on one circuit and one metro location despite requiring continuity during provider-level outages. Which response best addresses these needs?
- Add diverse eligible circuits and routing failover options across independent connectivity locations; do not evaluate ExpressRoute FastPath prerequisites and verify which traffic paths the selected gateway and routes support.
- Evaluate ExpressRoute FastPath prerequisites and verify which traffic paths the selected gateway and routes support; evaluate ExpressRoute Global Reach between eligible circuits and validate location and provider support.
- Evaluate ExpressRoute Direct with supported locations, port capacity, and operational requirements; add diverse eligible circuits and routing failover options across independent connectivity locations.
- Evaluate ExpressRoute FastPath prerequisites and verify which traffic paths the selected gateway and routes support; add diverse eligible circuits and routing failover options across independent connectivity locations.
Explanation
Correct Answer
D:FastPath can bypass parts of a supported gateway data path but is not automatically available for all circuit configurations. Physical provider and peering diversity address failures that redundant gateway instances on one circuit cannot. Both actions are needed.
Incorrect Answers
A:This plan leaves out a required action: Evaluate ExpressRoute FastPath prerequisites and verify which traffic paths the selected gateway and routes support. The remaining action alone does not satisfy the situation.
B:Physical provider and peering diversity address failures that redundant gateway instances on one circuit cannot.
C:FastPath can bypass parts of a supported gateway data path but is not automatically available for all circuit configurations.
Question 304
An engineering VNet has a /24 address space but must add separate application, private endpoint, gateway, and firewall subnets next quarter. A containerized service requires a subnet dedicated to a specific Azure platform integration, but deployment reports that delegation is missing. What is the most appropriate plan for this situation?
- Provision a dedicated GatewaySubnet with the required size and attach the virtual network gateway to that supported subnet; configure the service's supported subnet delegation and check whether other intended resources can share that subnet.
- Expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets before deploying new services; Redesign the Azure address plan using nonoverlapping prefixes and coordinate any required network translation before connecting the environments.
- Configure the service's supported subnet delegation and check whether other intended resources can share that subnet; do not Expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets before deploying new services.
- Expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets before deploying new services; configure the service's supported subnet delegation and check whether other intended resources can share that subnet.
Explanation
Correct Answer
D:Subnet capacity and reserved addresses must be planned for service-specific requirements rather than consumed opportunistically. A delegated subnet grants a compatible platform service authority over subnet operations and may limit colocated services. Both actions are needed.
Incorrect Answers
A:Subnet capacity and reserved addresses must be planned for service-specific requirements rather than consumed opportunistically.
B:A delegated subnet grants a compatible platform service authority over subnet operations and may limit colocated services.
C:This plan leaves out a required action: Expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets before deploying new services. The remaining action alone does not satisfy the situation.
Question 305
A backend pool is configured for HTTP/2-only application traffic while the gateway's supported backend mode differs from the client-side protocol expectation. A team wants end-to-end connection affinity for a stateful checkout service but uses an origin that stores carts only in local process memory. A regional Application Gateway deployment includes several separate backends but fails requests after a subnet routing change inserts an unsupported forced tunnel. Which course of action addresses the stated issues?
- Verify the supported Application Gateway frontend and backend protocol capabilities and match the origin application configuration; use supported multi-site HTTPS listeners and server name indication with valid certificates for each authorized hostname; and validate Application Gateway subnet and routing restrictions and repair the effective required control-plane and backend paths.
- Use supported multi-site HTTPS listeners and server name indication with valid certificates for each authorized hostname; configure supported cookie-based affinity where suitable and redesign session state for failover resilience; and validate Application Gateway subnet and routing restrictions and repair the effective required control-plane and backend paths.
- Verify the supported Application Gateway frontend and backend protocol capabilities and match the origin application configuration; configure supported cookie-based affinity where suitable and redesign session state for failover resilience; and validate Application Gateway subnet and routing restrictions and repair the effective required control-plane and backend paths.
- Verify the supported Application Gateway frontend and backend protocol capabilities and match the origin application configuration; configure supported cookie-based affinity where suitable and redesign session state for failover resilience; and use supported multi-site HTTPS listeners and server name indication with valid certificates for each authorized hostname.
Explanation
Correct Answer
C:A gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend. Sticky routing can reduce session churn but cannot protect application sessions when a single backend permanently fails. An Application Gateway still depends on documented networking prerequisites, including compatible routing through its subnet. Each decision addresses a separate requirement.
Incorrect Answers
A:Two actions meet their requirements, but action 2 misses this need: sticky routing can reduce session churn but cannot protect application sessions when a single backend permanently fails.
B:Two actions meet their requirements, but action 1 misses this need: a gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend.
D:Two actions meet their requirements, but action 3 misses this need: an Application Gateway still depends on documented networking prerequisites, including compatible routing through its subnet.
Question 306
A gateway terminates TLS from public clients, but the security policy requires HTTPS encryption to remain on the backend hop. An engineer creates two path rules but one broad basic rule captures every request, making the intended /admin routing ineffective. Which response best addresses these needs?
- Review listener and rule priorities and verify path-match precedence before committing the correction; do not configure HTTPS backend settings with appropriate certificate trust and end-to-end TLS validation.
- Configure a supported Application Gateway rewrite rule set and verify the forwarded request headers; review listener and rule priorities and verify path-match precedence before committing the correction.
- Configure HTTPS backend settings with appropriate certificate trust and end-to-end TLS validation; review listener and rule priorities and verify path-match precedence before committing the correction.
- Configure HTTPS backend settings with appropriate certificate trust and end-to-end TLS validation; correct backend hostname and trusted certificate settings and retest the Application Gateway health probe.
Explanation
Correct Answer
C:Frontend TLS termination alone does not guarantee that the gateway-to-origin hop is encrypted. Request routing priority determines which rule is evaluated when multiple definitions could match. Both actions are needed.
Incorrect Answers
A:This plan leaves out a required action: Configure HTTPS backend settings with appropriate certificate trust and end-to-end TLS validation. The remaining action alone does not satisfy the situation.
B:Frontend TLS termination alone does not guarantee that the gateway-to-origin hop is encrypted.
D:Request routing priority determines which rule is evaluated when multiple definitions could match.
Question 307
An ExpressRoute circuit is provisioned but a spoke VNet still has no on-premises reachability because no gateway connection exists. What should the Azure network engineer do?
- Configure Azure private peering and the applicable VNet gateway or direct connectivity model.
- Design an ExpressRoute circuit with an eligible connectivity provider and appropriate peering and gateway configuration.
- Align the provider handoff, BGP peer IPs, ASN, VLAN ID, and Microsoft peering configuration.
- Create a supported ExpressRoute virtual network gateway and link the VNet to the provisioned circuit.
Explanation
Correct Answer
D:Provisioning the circuit itself does not automatically connect a VNet's routing domain to the private peering.
Incorrect Answers
A:For this finding, provisioning the circuit itself does not automatically connect a VNet's routing domain to the private peering.
B:Designing an ExpressRoute circuit with an eligible connectivity provider and appropriate peering and gateway configuration would not create a supported ExpressRoute virtual network gateway and link the VNet to the provisioned circuit.
C:Aligning the provider handoff, BGP peer IPs, ASN, VLAN ID, and Microsoft peering configuration would not create a supported ExpressRoute virtual network gateway and link the VNet to the provisioned circuit.
Question 308
Multiple Azure Firewalls should share a baseline threat and network rule policy while allowing one region's justified exceptions. Which response best addresses this Azure networking scenario?
- Deploy a supported Azure Firewall secured virtual hub configuration and verify Virtual WAN routing intent and connections.
- Use Azure Firewall Policy hierarchy and appropriately scoped child policies with validation of rule collection priorities.
- Select an appropriate Azure Firewall Premium tier after validating required advanced security features.
- Update and associate approved route tables or secured hub routing intent and confirm packets traverse the firewall.
Explanation
Correct Answer
B:Central policy inheritance can standardize controls without copying every rule by hand into each firewall.
Incorrect Answers
A:For this finding, central policy inheritance can standardize controls without copying every rule by hand into each firewall.
C:Here, central policy inheritance can standardize controls without copying every rule by hand into each firewall.
D:For this question, central policy inheritance can standardize controls without copying every rule by hand into each firewall.
Question 309
An administrator creates a deny rule at priority 400 but a broader allow at priority 200 still admits the traffic. Which response best addresses this Azure networking scenario?
- Use supported Application Security Groups for member NICs and reference those groups in appropriate NSG rules.
- Reorder or narrow the higher-priority matching NSG rule and validate the effective security evaluation.
- Create a narrowly scoped inbound NSG rule with the specific source, destination, protocol, port, and appropriate priority.
- Check effective NSG rules across subnet and NIC scopes before changing unrelated Azure Firewall policies.
Explanation
Correct Answer
B:Lower numerical priority values are processed first, so an earlier matching allow can shadow a later deny.
Incorrect Answers
A:For this finding, lower numerical priority values are processed first, so an earlier matching allow can shadow a later deny.
C:Creating a narrowly scoped inbound NSG rule with the specific source, destination, protocol, port, and appropriate priority would not address the need for reorder or narrow the higher-priority matching NSG rule and validate the effective security evaluation.
D:Checking effective NSG rules across subnet and NIC scopes would not address the need for reorder or narrow the higher-priority matching NSG rule and validate the effective security evaluation.
Question 310
An administrator expects Application Gateway to provide raw RDP load balancing for remote administrators rather than web traffic. An application routes by hostname but uses a generic probe that targets the wrong virtual host and marks every endpoint down. What is the most appropriate plan for this situation?
- Use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol; update backend pool membership and probe configuration and verify traffic distribution from client requests.
- Use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol; configure probes with the intended host header and path and validate the origin's virtual host behavior.
- Set the backend HTTP port and probe destination correctly rather than changing the public HTTPS listener; configure probes with the intended host header and path and validate the origin's virtual host behavior.
- Configure probes with the intended host header and path and validate the origin's virtual host behavior; do not use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol.
Explanation
Correct Answer
B:Application Gateway focuses on HTTP(S) services and does not expose generic TCP connections like an L4 balancer. HTTP virtual hosting can return different health responses depending on the Host header sent by the probe. Both actions are needed.
Incorrect Answers
A:HTTP virtual hosting can return different health responses depending on the Host header sent by the probe.
C:Application Gateway focuses on HTTP(S) services and does not expose generic TCP connections like an L4 balancer.
D:This plan leaves out a required action: Use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol. The remaining action alone does not satisfy the situation.
