Read-only registry credentials cannot publish new manifests. Scope and role assignment must allow writes. This matters here because a startup-heavy app is repeatedly restarted by an aggressive liveness check. Which probe design should be reviewed.

Digests identify exact content independent of mutable tags. This reduces accidental deployment of an unreviewed artifact. This matters here because a startup-heavy app is repeatedly restarted by an aggressive liveness check. Which probe design should be reviewed.

A tag can move to another manifest while a digest identifies one immutable artifact. Update the deployment reference to roll out new bytes. This matters here because a startup-heavy app is repeatedly restarted by an aggressive liveness check. Which probe design should be reviewed.

Secrets avoid baking credentials into immutable image layers. Permissions, rotation and secret version handling still matter. This matters here because a data-processing container must run at a specific cron schedule and then exit. What Azure resource is designed for it.

ACI deployment is constrained by supported resource shapes and subscription quota. A correct container image cannot overcome unavailable capacity. This matters here because a data-processing container must run at a specific cron schedule and then exit. What Azure resource is designed for it.

Ingress is for inbound traffic; scheduled execution is a Container Apps Job with a valid schedule trigger.

Slot swapping promotes the candidate release while allowing preparatory warm-up. It is safer than deleting and recreating the application. This matters here because an App Service app must expose its runtime environment value differently in staging and production.

Private routing requires the standard hostname to resolve to the private endpoint address. Endpoint connection without DNS integration is insufficient. This matters here because an App Service app must expose its runtime environment value differently in staging and production.

Backup files are not a replacement for deployment-slot-specific application settings. Mark environment-dependent values as slot settings to keep staging and production separated.

Slot swapping promotes the candidate release while allowing preparatory warm-up. It is safer than deleting and recreating the application. This matters here because a staging-only API endpoint remains attached to the production slot after swap. Is that expected.

Sticky settings remain associated with their slot and avoid swapping protected environment values along with application content. This matters here because a staging-only API endpoint remains attached to the production slot after swap. Is that expected.

App Service offerings vary by operating system and runtime. A build that runs locally may need a compatible hosting configuration. This matters here because a staging-only API endpoint remains attached to the production slot after swap. Is that expected.

App Service backup does not automatically guarantee consistent recovery of every external database. Dependencies need coordinated RPO and RTO. This matters here because a web app in App Service has an unhealthy worker that should be removed from serving customer traffic. Which….

Always On sends periodic requests to keep the app loaded, reducing cold starts for applicable plans. This matters here because a web app in App Service has an unhealthy worker that should be removed from serving customer traffic. Which….

Private endpoints provide private network ingress to supported App Service apps. Regional VNet integration is for outbound app calls. This matters here because a web app in App Service has an unhealthy worker that should be removed from serving customer traffic. Which….

A slot cannot show whether the production database is reachable. Configure a Health Check endpoint that tests required dependencies and returns unhealthy status when they fail.

HTTPS Only enforces secure transport for inbound web requests. A valid certificate without enforcement does not guarantee every user avoids HTTP. This matters here because an application reports HTTP 200 on the root page but its required database is down.

A staging slot isolates the candidate release from ordinary customer traffic. A failed validation does not require replacing the live slot.

App Service manages supported application hosting and scaling features. A VM-hosted web server adds guest patching responsibilities. This matters here because a company wants automated scheduled backups for an App Service app and its supported content. Which feature is relevant.

Endpoint networking does not prevent idle unloads. Always On and the chosen hosting tier affect application readiness after inactivity. This matters here because a company wants automated scheduled backups for an App Service app and its supported content. Which feature is relevant.

DNS and App Service hostname mapping work together. A DNS record alone does not authorize the platform to serve the hostname. This matters here because a company wants automated scheduled backups for an App Service app and its supported content. Which feature is relevant.

Azure VNets can have multiple address spaces, subject to overlap, peerings and service constraints. Routing and existing subnets must be reviewed. This matters here because a VNet needs a dedicated subnet for Azure Bastion while keeping application VMs elsewhere. What subnet naming rule….

Bastion brokers approved RDP or SSH connections to VMs without public IPs on each guest. This matters here because a VNet needs a dedicated subnet for Azure Bastion while keeping application VMs elsewhere. What subnet naming rule….

Static private IP allocation makes the address stable across supported VM lifecycle events. DNS records must agree with the NIC configuration. This matters here because a VNet needs a dedicated subnet for Azure Bastion while keeping application VMs elsewhere. What subnet naming rule….

Azure Bastion requires the designated AzureBastionSubnet name and a supported subnet configuration. Capacity adjustments alone cannot fix a mismatched required name.

Subnet delegation constrains which service can manage certain resources in that subnet. Incompatible reuse can block deployment. This matters here because bastion deployment fails because its subnet is named bastion-subnet.

Azure VNets can have multiple address spaces, subject to overlap, peerings and service constraints. Routing and existing subnets must be reviewed. This matters here because bastion deployment fails because its subnet is named bastion-subnet.

Private DNS zones resolve within linked VNets rather than publishing records to the Internet. Links and resolver paths control client reachability. This matters here because an engineer wants to verify connectivity from a VM NIC to a private IP and port after applying UDRs. What Azure….

Two /25 blocks partition the /24 address space exactly. Their network boundaries align with the prefix size. This matters here because an engineer wants to verify connectivity from a VM NIC to a private IP and port after applying UDRs. What Azure….

Gateway-learned routes can appear in subnet effective routes under supported propagation and topology. A random public IP rule cannot establish private routing. This matters here because an engineer wants to verify connectivity from a VM NIC to a private IP and port after applying UDRs. What Azure….

Peering connectivity does not override security rules or guest firewalls. Connected peering is a network relationship, not authorization to every port. This matters here because connection troubleshoot reports a route to an NVA rather than direct peering.

Two /25 blocks partition the /24 address space exactly. Their network boundaries align with the prefix size. This matters here because connection troubleshoot reports a route to an NVA rather than direct peering.

Azure VM multi-NIC configurations have SKU and network constraints. A NIC cannot arbitrarily attach to every VNet. This matters here because connection troubleshoot reports a route to an NVA rather than direct peering.
