The team adopts "Verify the package image location, share access, identity and host permissions" for this AVD requirement: "An App attach package is uploaded but users receive a package mounting or accessibility error". Which explanation is correct?
App attach requires session hosts to read or mount the package artifact at the configured storage path. This is the specific underlying behavior that makes the proposed remediation fit the stated problem.
Application lifecycle controls determine availability, whereas user profile preservation is a separate concern. This describes the separate situation "An organization must remove an unapproved application from all new AVD sessions while preserving existing profiles" but does not justify the selected fix for the current issue. The decisive behavior is: App attach requires session hosts to read or mount the package artifact at the configured storage path.

The decisive behavior is: App attach requires session hosts to read or mount the package artifact at the configured storage path.
An Azure Virtual Desktop administrator observes: Users connect to the AVD broker but all session hosts fail reverse-connect control channel initialization. Which response directly addresses this issue?
Check required outbound TCP 443 access from session hosts to Azure Virtual Desktop service endpoints. Azure Virtual Desktop's reverse-connect transport requires outbound connectivity from hosts instead of exposing inbound RDP ports to the internet. This action directly addresses the conditions in the scenario.
Upgrade supported Windows App clients and confirm version prerequisites and multipath status. This would be appropriate for the different task-specific situation "Windows App clients running obsolete builds do not display the expected RDP Multipath transport options", because RDP Multipath feature availability depends on supported client platforms and minimum Windows App versions. It does not directly resolve the stated condition, which calls for Check required outbound TCP 443 access from session hosts to Azure Virtual Desktop service endpoints.
Inspect session connection information and AVD diagnostic connection records for transport details. This would be appropriate for the different task-specific situation "The team wants to identify whether AVD sessions used UDP Shortpath or TCP fallback during a fault", because Connection transport telemetry distinguishes the user data path independently of general VM health metrics. It does not directly resolve the stated condition, which calls for Check required outbound TCP 443 access from session hosts to Azure Virtual Desktop service endpoints.
Verify supported RDP Multipath client versions and monitor transport failover events. This would be appropriate for the different task-specific situation "Users report session drops when their laptops roam between Wi-Fi and mobile connectivity", because Multipath can switch among viable backup UDP or TCP paths when an active session route degrades. It does not directly resolve the stated condition, which calls for Check required outbound TCP 443 access from session hosts to Azure Virtual Desktop service endpoints.
A Microsoft AZ-140 deployment review finds: An organization wants to consolidate user sessions onto fewer powered-on hosts to reduce compute spend. What is the best corrective action?

It does not directly resolve the stated condition, which calls for Configure depth-first load balancing with appropriate session limits and autoscale controls.
Test workload isolation, sizing and optimized application delivery before changing the entire assignment model. This would be appropriate for the different task-specific situation "A planning team proposes replacing all pooled desktops with personal VMs after noticing one application's high CPU use", because A single resource-intensive app does not by itself prove every user needs dedicated desktop infrastructure. It does not directly resolve the stated condition, which calls for Configure depth-first load balancing with appropriate session limits and autoscale controls.
An AZ-140 reviewer recommends "Evaluate supported regional placement for both storage and session hosts before increasing CPU" for the issue "A large host pool accesses a profile storage volume from a different region over a high-latency path". Which underlying behavior is decisive?
Remote file operations across regional boundaries can add material profile mount latency. This is the specific underlying behavior that makes the proposed remediation fit the stated problem.

It does not directly resolve the stated condition, which calls for Configure and customize Azure Virtual Desktop Insights with required diagnostic data sources.
Tune ramp-down session handling, disconnect timeout and deallocation policies. This would be appropriate for the different task-specific situation "A scaling plan powers off hosts too aggressively while employees have disconnected but resumable sessions", because Autoscale decisions must account for existing user session state to avoid disruption. It does not directly resolve the stated condition, which calls for Configure and customize Azure Virtual Desktop Insights with required diagnostic data sources.
Use session counts and host availability trends to refine scaling plan ramp-up times. This would be appropriate for the different task-specific situation "A host pool shows insufficient available session capacity during a predictable daily spike", because Scaling before known peak demand helps ensure ready capacity is available at sign-in. It does not directly resolve the stated condition, which calls for Configure and customize Azure Virtual Desktop Insights with required diagnostic data sources.
Consider this AVD design: The enterprise firewall permits a few static AVD IP addresses but connections fail after Microsoft service changes. The action is "Use the documented Azure Virtual Desktop required endpoint and service-tag guidance instead of a fragile hard-coded address list". Which statement explains this choice?
Service endpoints and IP ranges can change, so supported FQDN and service-tag approaches simplify maintained egress policies. This is the specific underlying behavior that makes the proposed remediation fit the stated problem.
Multipath can switch among viable backup UDP or TCP paths when an active session route degrades. This describes the separate situation "Users report session drops when their laptops roam between Wi-Fi and mobile connectivity" but does not justify the selected fix for the current issue. The decisive behavior is: Service endpoints and IP ranges can change, so supported FQDN and service-tag approaches simplify maintained egress policies.
RDP Shortpath over a managed network can establish direct UDP transport when client and host have suitable private connectivity. This describes the separate situation "Session hosts connect to an on-premises domain controller over ExpressRoute but user sessions still take TCP reverse-connect paths" but does not justify the selected fix for the current issue. The decisive behavior is: Service endpoints and IP ranges can change, so supported FQDN and service-tag approaches simplify maintained egress policies.
QoS traffic classification can protect latency-sensitive remote desktop flows under congestion. This describes the separate situation "A branch has competing real-time desktop audio and bulk file traffic over one constrained WAN circuit" but does not justify the selected fix for the current issue. The decisive behavior is: Service endpoints and IP ranges can change, so supported FQDN and service-tag approaches simplify maintained egress policies.
For a deployment problem, "The team builds session host images without recording which Windows cumulative updates were present", administrators choose "Record OS build and installed patch level as part of every image release and compliance check". Why does that solve it?
