Microsoft AZ-305 Practice Test 88
Question 870
Acceptance testing must establish the following operational result: Path evidence confirms forced routing. Which verification action most directly establishes that outcome?
- Correlate source/destination packet test with the firewall's rule hit.
- Inspect effective routes and observe flow through the appliance.
- Test an allowed destination and a denied domain or IP from a spoke.
- Exercise a TCP connection and simulate a backend failure.
Explanation
Correct Answer
B:Path evidence confirms forced routing.
Incorrect Answers
A:That verification addresses the different requirement: An internal firewall rule logs denied traffic that network operators cannot explain. It does not directly establish path evidence confirms forced routing.
C:That verification addresses the different requirement: A hub must inspect outbound traffic from many spokes and restrict destinations by policy. It does not directly establish path evidence confirms forced routing.
D:This is a test for A non-HTTP TCP application needs regional private load distribution among backend VMs. The requirement here is instead demonstrated by inspect effective routes and observe flow through the appliance.
Question 871
An internal firewall rule logs denied traffic that network operators cannot explain. Which Azure architecture choice best meets this requirement?
- Use firewall diagnostic logs and effective routes to distinguish policy block from routing failure.
- Grant the source VM Owner rights to bypass an IP firewall denial.
- Configure only default NSG allow-all rules on every subnet.
- Change only the NSG rule and assume it rewrites the route table.
Explanation
Correct Answer
A:Both forwarding policy and route selection affect end-to-end connectivity.
Incorrect Answers
B:RBAC management privilege does not replace network firewall rules. This proposal contradicts the stated architecture constraint.
C:NSGs without proper restrictions do not provide centralized controlled egress. In the present requirement, an internal firewall rule logs denied traffic that network operators cannot explain. The needed design instead works because both forwarding policy and route selection affect end-to-end connectivity.
D:NSGs filter traffic but do not choose the next hop. In the present requirement, an internal firewall rule logs denied traffic that network operators cannot explain. The needed design instead works because both forwarding policy and route selection affect end-to-end connectivity.
Question 872
An architecture proposal for azure firewall and routing control relies on the following approach: Grant the source VM Owner rights to bypass an IP firewall denial. Which specific failure or mismatch should the design reviewer identify?
- NSGs filter traffic but do not choose the next hop.
- RBAC management privilege does not replace network firewall rules.
- NSGs without proper restrictions do not provide centralized controlled egress.
- Authorization cannot repair name resolution to the wrong endpoint.
Explanation
Correct Answer
B:Grant the source VM Owner rights to bypass an IP firewall denial. RBAC management privilege does not replace network firewall rules.
Incorrect Answers
A:That assessment refers to the separate proposal 'Change only the NSG rule and assume it rewrites the route table.' not to the recommendation under review. Here, RBAC management privilege does not replace network firewall rules.
C:That assessment refers to the separate proposal 'Configure only default NSG allow-all rules on every subnet.' not to the recommendation under review. Here, RBAC management privilege does not replace network firewall rules.
D:This concern applies to Change only the PaaS service's RBAC role and ignore DNS routing. in another design network solutions design. The current proposal specifically fails because rBAC management privilege does not replace network firewall rules.
Question 873
Acceptance testing must establish the following operational result: The match identifies whether denial is policy or reachability. Which verification action most directly establishes that outcome?
- Test an allowed destination and a denied domain or IP from a spoke.
- Query DNS from on-premises and Azure clients and compare resolved private addresses.
- Correlate source/destination packet test with the firewall's rule hit.
- Inspect effective routes and observe flow through the appliance.
Explanation
Correct Answer
C:The match identifies whether denial is policy or reachability.
Incorrect Answers
A:That verification addresses the different requirement: A hub must inspect outbound traffic from many spokes and restrict destinations by policy. It does not directly establish the match identifies whether denial is policy or reachability.
B:This is a test for A private endpoint resolves to a public PaaS IP from one on-premises DNS server. The requirement here is instead demonstrated by correlate source/destination packet test with the firewall's rule hit.
D:That verification addresses the different requirement: Sensitive production traffic must traverse an NVA, but packets currently take a direct system route. It does not directly establish the match identifies whether denial is policy or reachability.
Question 874

- Use only a public IP allowlist and call the endpoint private.
- Grant broad subscription Owner to repair DNS resolution.
- Configure a service private endpoint and appropriate network access policy.
- Provide private DNS resolution from both Azure and hybrid clients.
- Assume a service endpoint creates the same private NIC as a private endpoint.
Explanation
Correct Answers
C:Private Link gives the service a private network interface.
D:Clients must resolve the service hostname to the correct private address.
Incorrect Answers
A:A public endpoint remains publicly addressed.
B:Management RBAC does not fix hostname resolution.
E:The two network features have different endpoint models.
Question 875
An architecture proposal for private link and service endpoints relies on the following approach: Rely only on a public IP allowlist and call the endpoint private. Which specific failure or mismatch should the design reviewer identify?
- A public allowlist does not eliminate the publicly addressed endpoint.
- Service endpoints secure Azure service routing but do not create Private Link interfaces.
- NSGs filter traffic but do not choose the next hop.
- Authorization cannot repair name resolution to the wrong endpoint.
Explanation
Correct Answer
A:Rely only on a public IP allowlist and call the endpoint private. A public allowlist does not eliminate the publicly addressed endpoint.
Incorrect Answers
B: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, A public allowlist does not eliminate the publicly addressed endpoint.
C:This concern applies to Change only the NSG rule and assume it rewrites the route table. in another design network solutions design. The current proposal specifically fails because a public allowlist does not eliminate the publicly addressed endpoint.
D:That assessment refers to the separate proposal 'Change only the PaaS service's RBAC role and ignore DNS routing.' not to the recommendation under review. Here, A public allowlist does not eliminate the publicly addressed endpoint.
Question 876
Acceptance testing must establish the following operational result: DNS and packet tests validate the private path. Which verification action most directly establishes that outcome?
- Check effective endpoint routes and permitted storage resource access.
- Query DNS from on-premises and Azure clients and compare resolved private addresses.
- Inspect effective routes and observe flow through the appliance.
- Resolve service FQDN and test private IP connectivity with public access disabled.
Explanation
Correct Answer
D:DNS and packet tests validate the private path.
Incorrect Answers
A: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 DNS and packet tests validate the private path.
B:That verification addresses the different requirement: A private endpoint resolves to a public PaaS IP from one on-premises DNS server. It does not directly establish DNS and packet tests validate the private path.
C:This is a test for Sensitive production traffic must traverse an NVA, but packets currently take a direct system route. The requirement here is instead demonstrated by resolve service FQDN and test private IP connectivity with public access disabled.

C:Endpoint policies can constrain reachable eligible Azure storage resources.
Incorrect Answers
A:A public allowlist does not eliminate the publicly addressed endpoint. In the present requirement, an app subnet wants to restrict which Azure Storage accounts can be accessed through a service endpoint design. The needed design instead works because endpoint policies can constrain reachable eligible Azure storage resources.
B:Service endpoints secure Azure service routing but do not create Private Link interfaces. This proposal contradicts the stated architecture constraint.
D:Authorization cannot repair name resolution to the wrong endpoint. In the present requirement, an app subnet wants to restrict which Azure Storage accounts can be accessed through a service endpoint design. The needed design instead works because endpoint policies can constrain reachable eligible Azure storage resources.

- 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
C:Assume enabling a service endpoint creates a private NIC for the service inside the VNet. Service endpoints secure Azure service routing but do not create Private Link interfaces.
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, Service endpoints secure Azure service routing but do not create Private Link interfaces.
B:This concern applies to Treat private carrier routing as proof all application traffic is encrypted. in another design network solutions design. The current proposal specifically fails because service endpoints secure Azure service routing but do not create Private Link interfaces.
