Microsoft AZ-305 Practice Test 89
Question 880
A private endpoint resolves to a public PaaS IP from one on-premises DNS server. Which Azure architecture choice best meets this requirement?
- Change only the PaaS service's RBAC role and ignore DNS routing.
- Configure hybrid private DNS resolution for the relevant privatelink zone.
- Assume enabling a service endpoint creates a private NIC for the service inside the VNet.
- Rely only on a public IP allowlist and call the endpoint private.
Explanation
Correct Answer
B:Private Link access relies on correct split-horizon DNS from each client network.
Incorrect Answers
A:Authorization cannot repair name resolution to the wrong endpoint. This proposal contradicts the stated architecture constraint.
C:Service endpoints secure Azure service routing but do not create Private Link interfaces. In the present requirement, a private endpoint resolves to a public PaaS IP from one on-premises DNS server. The needed design instead works because private Link access relies on correct split-horizon DNS from each client network.
D:A public allowlist does not eliminate the publicly addressed endpoint. In the present requirement, a private endpoint resolves to a public PaaS IP from one on-premises DNS server. The needed design instead works because private Link access relies on correct split-horizon DNS from each client network.
Question 881
An architecture proposal for private link and service endpoints relies on the following approach: Change only the PaaS service's RBAC role and ignore DNS routing. Which specific failure or mismatch should the design reviewer identify?
- A public allowlist does not eliminate the publicly addressed endpoint.
- Overlap prevents straightforward routed reachability and scaling.
- Service endpoints secure Azure service routing but do not create Private Link interfaces.
- Authorization cannot repair name resolution to the wrong endpoint.
Explanation
Correct Answer
D:Change only the PaaS service's RBAC role and ignore DNS routing. Authorization cannot repair name resolution to the wrong endpoint.
Incorrect Answers
A:That assessment refers to the separate proposal 'Rely only on a public IP allowlist and call the endpoint private.' not to the recommendation under review. Here, Authorization cannot repair name resolution to the wrong endpoint.
B:This concern applies to Place every VNet into one flat address range with overlapping subnets. in another design network solutions design. The current proposal specifically fails because authorization cannot repair name resolution to the wrong endpoint.
C:That assessment refers to the separate proposal 'Assume enabling a service endpoint creates a private NIC for the service inside the VNet.' not to the recommendation under review. Here, Authorization cannot repair name resolution to the wrong endpoint.
Question 882
Acceptance testing must establish the following operational result: Matching private resolution confirms DNS integration. Which verification action most directly establishes that outcome?
- Query DNS from on-premises and Azure clients and compare resolved private addresses.
- Test spoke-to-hub paths and verify effective routes.
- Resolve service FQDN and test private IP connectivity with public access disabled.
- Check effective endpoint routes and permitted storage resource access.
Explanation
Correct Answer
A:Matching private resolution confirms DNS integration.
Incorrect Answers
B:This is a test for Several app VNets need controlled access to shared DNS and firewall services. The requirement here is instead demonstrated by query DNS from on-premises and Azure clients and compare resolved private addresses.
C:That verification addresses the different requirement: A PaaS database must be reached from a VNet without accepting traffic on its public endpoint. It does not directly establish matching private resolution confirms DNS integration.
D:That verification addresses the different requirement: An app subnet wants to restrict which Azure Storage accounts can be accessed through a service endpoint design. It does not directly establish matching private resolution confirms DNS integration.
Question 883
A regional HTTPS service requires path-based routing to separate API and static application backends. Which Azure architecture choice best meets this requirement?
- Use an NSG only and assume it inspects SQL injection request payloads.
- Continue routing to every open TCP port even when the application is unhealthy.
- Use only a network Load Balancer rule that cannot inspect URLs.
- Deploy Application Gateway with listeners and path routing rules.
Explanation
Correct Answer
D:Layer 7 gateway routing can select HTTP backends by URL path and hostname.
Incorrect Answers
A:NSGs match network traffic properties, not full HTTP application content. In the present requirement, a regional HTTPS service requires path-based routing to separate API and static application backends. The needed design instead works because layer 7 gateway routing can select HTTP backends by URL path and hostname.
B:Socket availability does not prove login or backend dependencies work. In the present requirement, a regional HTTPS service requires path-based routing to separate API and static application backends. The needed design instead works because layer 7 gateway routing can select HTTP backends by URL path and hostname.
C:Layer 4 load balancing lacks HTTP path awareness. This proposal contradicts the stated architecture constraint.
Question 884
An architecture proposal for application gateway and waf relies on the following approach: Use only a network Load Balancer rule that cannot inspect URLs. Which specific failure or mismatch should the design reviewer identify?
- Layer 4 load balancing lacks HTTP path awareness.
- NSGs match network traffic properties, not full HTTP application content.
- Address overlaps complicate or prevent VNet peering and route distinction.
- Socket availability does not prove login or backend dependencies work.
Explanation
Correct Answer
A:Use only a network Load Balancer rule that cannot inspect URLs. Layer 4 load balancing lacks HTTP path awareness.
Incorrect Answers
B:That assessment refers to the separate proposal 'Use an NSG only and assume it inspects SQL injection request payloads.' not to the recommendation under review. Here, Layer 4 load balancing lacks HTTP path awareness.
C:This concern applies to Reuse the same RFC1918 subnet in every VNet and assume peering resolves it. in another design network solutions design. The current proposal specifically fails because layer 4 load balancing lacks HTTP path awareness.
D:That assessment refers to the separate proposal 'Continue routing to every open TCP port even when the application is unhealthy.' not to the recommendation under review. Here, Layer 4 load balancing lacks HTTP path awareness.
Question 885
Acceptance testing must establish the following operational result: Routing tests validate path selection. Which verification action most directly establishes that outcome?
- Validate VNet CIDRs against on-premises and planned regions.
- Send an approved WAF test payload and review resulting logs.
- Send requests to two paths and inspect destination backends.
- Simulate the dependency fault and inspect gateway backend health.
Explanation
Correct Answer
C:Routing tests validate path selection.
Incorrect Answers
A:This is a test for A company plans IP ranges for 60 VNets across regions and must avoid future address conflicts. The requirement here is instead demonstrated by send requests to two paths and inspect destination backends.
B:That verification addresses the different requirement: A public ecommerce site must inspect common SQL injection patterns before requests reach its web tier. It does not directly establish routing tests validate path selection.
D:That verification addresses the different requirement: The new web deployment passes its TCP probe but fails application login because an identity provider is down. It does not directly establish routing tests validate path selection.
Question 886
A public ecommerce site must inspect common SQL injection patterns before requests reach its web tier. Which Azure architecture choice best meets this requirement?
