Question 240
A marketing site needs weighted distribution of new DNS lookups between regional hostnames for controlled rollout. A network engineer demands TLS termination and WAF inspection directly on a Traffic Manager DNS profile. Which response best addresses these needs?
- Review DNS caching and TTL behavior and design client retry expectations for Traffic Manager failover; use a supported web delivery layer such as Front Door or Application Gateway for TLS and WAF inspection.
- Use Traffic Manager weighted routing with monitored endpoints and validate the resulting DNS responses; 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; use a supported web delivery layer such as Front Door or Application Gateway for TLS and WAF inspection.
- Use a supported web delivery layer such as Front Door or Application Gateway for TLS and WAF inspection; do not use Traffic Manager weighted routing with monitored endpoints and validate the resulting DNS responses.
Explanation
Correct Answer
C:Weighted DNS routing can steer new resolver answers without providing layer-7 application transformations. A DNS traffic manager does not terminate HTTP/TLS connections or inspect request payloads. Both actions are needed.
Incorrect Answers
A:Weighted DNS routing can steer new resolver answers without providing layer-7 application transformations.
B:A DNS traffic manager does not terminate HTTP/TLS connections or inspect request payloads.
D:This plan leaves out a required action: Use Traffic Manager weighted routing with monitored endpoints and validate the resulting DNS responses. The remaining action alone does not satisfy the situation.
Question 241
A worldwide retail site needs Microsoft edge-based HTTP routing, TLS termination, caching, and automatic origin health failover. Which response most directly resolves the issue?
- 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.
- 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.
Explanation
Correct Answer
A:Front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing.
Incorrect Answers
B:Here, front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing.
C:For this question, front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing.
D:For this finding, front Door provides global layer-7 ingress and origin routing rather than only regional private load balancing.
Question 242
A VNet is configured with an alternate DNS server address, but the team attributes unrelated IP exhaustion to DNS settings. A peered VNet retains a default address range that duplicates an on-premises production prefix, and routing fails after VPN connection. Which course of action addresses the stated issues?
- Investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration; check supported global or cross-region load-balancing constructs and separate regional address identities where required.
- 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; Resolve the address overlap before deploying peering and hybrid route advertisements into the same connectivity topology.
- Resolve the address overlap before deploying peering and hybrid route advertisements into the same connectivity topology; do not investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration.
Explanation
Correct Answer
C:Name resolution settings do not increase the number of assignable private addresses in a subnet. Overlapping advertised prefixes undermine deterministic routing regardless of gateway health. Both actions are needed.
Incorrect Answers
A:Overlapping advertised prefixes undermine deterministic routing regardless of gateway health.
B:Name resolution settings do not increase the number of assignable private addresses in a subnet.
D:This plan leaves out a required action: Investigate subnet IP assignments and available CIDR capacity independently from DNS resolver configuration. The remaining action alone does not satisfy the situation.
Question 243
During an Azure networking rollout, the team must resolve both of these conditions. Two enterprise datacenters need private connectivity to each other through Microsoft's backbone, not just reach Azure resources. An organization orders high-capacity dedicated ExpressRoute connectivity that requires paired physical links and direct Microsoft edge port management. Which response best addresses these needs?
- Add diverse eligible circuits and routing failover options across independent connectivity locations; evaluate ExpressRoute Direct with supported locations, port capacity, and operational requirements.
- Evaluate ExpressRoute Global Reach between eligible circuits and validate location and provider 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.
- Evaluate ExpressRoute Direct with supported locations, port capacity, and operational requirements; do not evaluate ExpressRoute Global Reach between eligible circuits and validate location and provider support.
Explanation
Correct Answer
C:Global Reach joins supported on-premises sites through ExpressRoute circuits subject to geographic and SKU constraints. ExpressRoute Direct exposes dedicated port arrangements beyond a standard provider-managed circuit. Both actions are needed.
Incorrect Answers
A:Global Reach joins supported on-premises sites through ExpressRoute circuits subject to geographic and SKU constraints.
B:ExpressRoute Direct exposes dedicated port arrangements beyond a standard provider-managed circuit.
D:This plan leaves out a required action: Evaluate ExpressRoute Global Reach between eligible circuits and validate location and provider support. The remaining action alone does not satisfy the situation.
Question 244
An engineering VNet has a /24 address space but must add separate application, private endpoint, gateway, and firewall subnets next quarter. What should the Azure network engineer do?
- Expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets before deploying new services.
- 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.
- Redesign the Azure address plan using nonoverlapping prefixes and coordinate any required network translation before connecting the environments.
Explanation
Correct Answer
A:Subnet capacity and reserved addresses must be planned for service-specific requirements rather than consumed opportunistically.
Incorrect Answers
B:For this finding, subnet capacity and reserved addresses must be planned for service-specific requirements rather than consumed opportunistically.
C:Configuring the service's supported subnet delegation and checking whether other intended resources can share that subnet would not expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets.
D:Redesigning the Azure address plan using nonoverlapping prefixes and coordinate any required network translation would not expand or redesign the VNet address space and reserve appropriately sized nonoverlapping subnets.
Question 245
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. What should the Azure network engineer do?
- Validate Application Gateway subnet and routing restrictions and repair the effective required control-plane and backend paths.
- Configure supported cookie-based affinity where suitable and redesign session state for failover resilience.
- 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.
Explanation
Correct Answer
C:A gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend.
Incorrect Answers
A:An Application Gateway still depends on documented networking prerequisites, including compatible routing through its subnet. A gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend.
B:Sticky routing can reduce session churn but cannot protect application sessions when a single backend permanently fails. A gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend.
D:Hostname-aware HTTPS binding permits multiple domains on shared frontend infrastructure without substituting one invalid certificate. A gateway's client-facing protocol does not automatically imply identical protocol negotiation toward the backend.
Question 246
An application migrates from a legacy backend host name and now receives 502 responses because its certificate does not match the host selected by the gateway. A gateway must add an X-Forwarded custom header for upstream application diagnostics without changing application binaries. 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?
- Correct backend hostname and trusted certificate settings and retest the Application Gateway health probe; configure a supported Application Gateway rewrite rule set and verify the forwarded request headers; and 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; configure a supported Application Gateway rewrite rule set and verify the forwarded request headers; and review listener and rule priorities and verify path-match precedence before committing the correction.
- Correct backend hostname and trusted certificate settings and retest the Application Gateway health probe; configure HTTPS backend settings with appropriate certificate trust and end-to-end TLS validation; and 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; configure a supported Application Gateway rewrite rule set and verify the forwarded request headers; and review listener and rule priorities and verify path-match precedence before committing the correction.
Explanation
Correct Answer
B:Backend TLS validation depends on the expected name and chain, not just a responding TCP port. Gateway rewrite rules modify eligible HTTP metadata without requiring changes to every backend service. Request routing priority determines which rule is evaluated when multiple definitions could match. Each decision addresses a separate requirement.
Incorrect Answers
A:Two actions meet their requirements, but action 3 misses this need: request routing priority determines which rule is evaluated when multiple definitions could match.
C:Two actions meet their requirements, but action 2 misses this need: gateway rewrite rules modify eligible HTTP metadata without requiring changes to every backend service.
D:Two actions meet their requirements, but action 1 misses this need: backend TLS validation depends on the expected name and chain, not just a responding TCP port.
Question 247
An engineer configures Microsoft peering when the requirement is to reach VM private IPs in Azure VNets. A circuit's provider reports ready, but BGP sessions do not establish because the configured peer ASN and VLAN values disagree. What is the most appropriate plan for this situation?
- Configure Azure private peering and the applicable VNet gateway or direct connectivity model; 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; align the provider handoff, BGP peer IPs, ASN, VLAN ID, and Microsoft peering configuration.
- Align the provider handoff, BGP peer IPs, ASN, VLAN ID, and Microsoft peering configuration; do not configure Azure private peering and the applicable VNet gateway or direct connectivity model.
- 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.
Explanation
Correct Answer
A:Microsoft peering is not a substitute for Azure private peering to VNet private address space. ExpressRoute service provisioning and route exchange are separate milestones with strict peering parameters. Both actions are needed.
Incorrect Answers
B:Microsoft peering is not a substitute for Azure private peering to VNet private address space.
C:This plan leaves out a required action: Configure Azure private peering and the applicable VNet gateway or direct connectivity model. The remaining action alone does not satisfy the situation.
D:ExpressRoute service provisioning and route exchange are separate milestones with strict peering parameters.
Question 248
Multiple Azure Firewalls should share a baseline threat and network rule policy while allowing one region's justified exceptions. An Azure Firewall deployment has apparently correct allow rules, but spokes bypass its IP because their UDRs still point to the internet. Which course of action addresses the stated issues?
- 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; do not use Azure Firewall Policy hierarchy and appropriately scoped child policies with validation of rule collection priorities.
- Use Azure Firewall Policy hierarchy and appropriately scoped child policies with validation of rule collection priorities; update and associate approved route tables or secured hub routing intent and confirm packets traverse the firewall.
- Deploy a supported Azure Firewall secured virtual hub configuration and verify Virtual WAN routing intent and connections; update and associate approved route tables or secured hub routing intent and confirm packets traverse the firewall.
Explanation
Correct Answer
C:Central policy inheritance can standardize controls without copying every rule by hand into each firewall. A correctly configured firewall cannot inspect traffic that never traverses its private data-path endpoint. Both actions are needed.
Incorrect Answers
A:A correctly configured firewall cannot inspect traffic that never traverses its private data-path endpoint.
B:This plan leaves out a required action: Use Azure Firewall Policy hierarchy and appropriately scoped child policies with validation of rule collection priorities. The remaining action alone does not satisfy the situation.
D:Central policy inheritance can standardize controls without copying every rule by hand into each firewall.
Question 249
A security engineer attaches a restrictive NSG to a VM NIC but forgets an additional subnet NSG is also applied and traffic remains blocked. What should the Azure network engineer do?
- Create a narrowly scoped inbound NSG rule with the specific source, destination, protocol, port, and appropriate priority.
- Reorder or narrow the higher-priority matching NSG rule and validate the effective security evaluation.
- Use supported Application Security Groups for member NICs and reference those groups in appropriate NSG rules.
- Check effective NSG rules across subnet and NIC scopes before changing unrelated Azure Firewall policies.
Explanation
Correct Answer
D:Subnet and NIC security rules can both affect traffic; one permissive policy does not override a deny elsewhere.
Incorrect Answers
A:For this question, subnet and NIC security rules can both affect traffic; one permissive policy does not override a deny elsewhere.
B:Here, subnet and NIC security rules can both affect traffic; one permissive policy does not override a deny elsewhere.
C:For this finding, subnet and NIC security rules can both affect traffic; one permissive policy does not override a deny elsewhere.
Question 250
An application routes by hostname but uses a generic probe that targets the wrong virtual host and marks every endpoint down. Which action best addresses this finding?
- Update backend pool membership and probe configuration and verify traffic distribution from client requests.
- 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.
- Use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol.
Explanation
Correct Answer
B:HTTP virtual hosting can return different health responses depending on the Host header sent by the probe.
Incorrect Answers
A:For this question, hTTP virtual hosting can return different health responses depending on the Host header sent by the probe.
C:For this finding, hTTP virtual hosting can return different health responses depending on the Host header sent by the probe.
D:Here, hTTP virtual hosting can return different health responses depending on the Host header sent by the probe.
