Certificate upload and active binding are distinct management steps. In this case, a staging slot exists but it receives no user testing traffic. “The expected hostname binding may still refer to the previous certificate” would not satisfy that requirement; the supported action is “Route an appropriate percentage of traffic to the test slot where supported”. A slot's existence alone does not create a canary audience.

Expired or unbound certificates cause browser trust errors on custom domains. In this case, a staging slot exists but it receives no user testing traffic. “TLS certificate validity and current hostname binding” would not satisfy that requirement; the supported action is “Route an appropriate percentage of traffic to the test slot where supported”. A slot's existence alone does not create a canary audience.

Source code versioning may not retain runtime settings and application data. In this case, a staging slot exists but it receives no user testing traffic. “Plan application backup or redeployment of configuration and dependent data” would not satisfy that requirement; the supported action is “Route an appropriate percentage of traffic to the test slot where supported”. A slot's existence alone does not create a canary audience.

Always On keeps the app loaded by sending periodic requests to its root. In this case, a web app's custom hostname shows certificate warnings after renewal. “Enable Always On in an eligible App Service plan” would not satisfy that requirement; the supported action is “TLS certificate validity and current hostname binding”. Expired or unbound certificates cause browser trust errors on custom domains.

Slot traffic percentage routing supports controlled gradual exposure. In this case, a web app's custom hostname shows certificate warnings after renewal. “Use deployment-slot traffic routing for a supported phased release” would not satisfy that requirement; the supported action is “TLS certificate validity and current hostname binding”. Expired or unbound certificates cause browser trust errors on custom domains.

Expired or unbound certificates cause browser trust errors on custom domains.

Always On availability depends on plan tier and is not universal. In this case, a valid certificate is uploaded but HTTPS still presents an old certificate. “Move to an eligible plan and enable Always On” would not satisfy that requirement; the supported action is “The expected hostname binding may still refer to the previous certificate”. Certificate upload and active binding are distinct management steps.

Application Insights can collect application-level request and exception telemetry. In this case, an App Service app needs a warm instance to minimize cold starts. “Configure Application Insights for the application” would not satisfy that requirement; the supported action is “Enable Always On in an eligible App Service plan”. Always On keeps the app loaded by sending periodic requests to its root.

Expired or unbound certificates cause browser trust errors on custom domains. In this case, an App Service app needs a warm instance to minimize cold starts. “TLS certificate validity and current hostname binding” would not satisfy that requirement; the supported action is “Enable Always On in an eligible App Service plan”. Always On keeps the app loaded by sending periodic requests to its root.

Infrastructure CPU metrics do not explain every application error. In this case, an App Service app needs a warm instance to minimize cold starts. “Application Insights request failures and exception traces” would not satisfy that requirement; the supported action is “Enable Always On in an eligible App Service plan”. Always On keeps the app loaded by sending periodic requests to its root.

Expired or unbound certificates cause browser trust errors on custom domains. In this case, an idle app on a Free plan frequently spins up on first access. “TLS certificate validity and current hostname binding” would not satisfy that requirement; the supported action is “Move to an eligible plan and enable Always On”. Always On availability depends on plan tier and is not universal.

Always On keeps the app loaded by sending periodic requests to its root. In this case, a team needs to view failed application requests and traces from App Service. “Enable Always On in an eligible App Service plan” would not satisfy that requirement; the supported action is “Configure Application Insights for the application”.

Always On availability depends on plan tier and is not universal. In this case, a platform metrics chart shows CPU fine but requests fail with exceptions. “Move to an eligible plan and enable Always On” would not satisfy that requirement; the supported action is “Application Insights request failures and exception traces”.

Subnets must fall within the VNet address space and avoid duplicate IP coverage. In this case, a VNet has address space 10.20.0.0/16 and needs a subnet for 200 hosts. “Choose nonoverlapping CIDR ranges contained in the VNet address space” would not satisfy that requirement; the supported action is “A nonoverlapping /24 subnet within the VNet”. A /24 supplies 256 IPv4 addresses, with Azure reserving five, leaving enough for 200 hosts.

Azure subnets within a VNet must not overlap one another. In this case, a VNet has address space 10.20.0.0/16 and needs a subnet for 200 hosts. “Choose a prefix that does not overlap the existing /24” would not satisfy that requirement; the supported action is “A nonoverlapping /24 subnet within the VNet”. A /24 supplies 256 IPv4 addresses, with Azure reserving five, leaving enough for 200 hosts.

Standard VNet peering does not support overlapping address spaces. In this case, a VNet has address space 10.20.0.0/16 and needs a subnet for 200 hosts. “Renumber one network or design nonoverlapping address spaces” would not satisfy that requirement; the supported action is “A nonoverlapping /24 subnet within the VNet”. A /24 supplies 256 IPv4 addresses, with Azure reserving five, leaving enough for 200 hosts.

Subnets must fall within the VNet address space and avoid duplicate IP coverage. In this case, an admin creates 10.20.1.0/28 for 20 hosts and deployment fails. “Choose nonoverlapping CIDR ranges contained in the VNet address space” would not satisfy that requirement; the supported action is “A /28 leaves only eleven usable IP addresses after Azure reservations”. Subnet sizing must account for Azure-reserved addresses and expected instances.

Subnet sizing must account for Azure-reserved addresses and expected instances.

VNet peering provides private connectivity between compatible Azure virtual networks. In this case, an admin creates 10.20.1.0/28 for 20 hosts and deployment fails. “Configure VNet peering with compatible nonoverlapping addresses” would not satisfy that requirement; the supported action is “A /28 leaves only eleven usable IP addresses after Azure reservations”. Subnet sizing must account for Azure-reserved addresses and expected instances.

A /24 supplies 256 IPv4 addresses, with Azure reserving five, leaving enough for 200 hosts. In this case, a subnet uses 10.1.0.0/24 and the team wants to add 10.1.0.128/25 as a second subnet. “A nonoverlapping /24 subnet within the VNet” would not satisfy that requirement; the supported action is “Choose a prefix that does not overlap the existing /24”.

Azure subnets within a VNet must not overlap one another.

A /24 supplies 256 IPv4 addresses, with Azure reserving five, leaving enough for 200 hosts. In this case, an admin needs two disjoint subnets inside 10.1.0.0/23. “A nonoverlapping /24 subnet within the VNet” would not satisfy that requirement; the supported action is “Choose nonoverlapping CIDR ranges contained in the VNet address space”. Subnets must fall within the VNet address space and avoid duplicate IP coverage.
