1Y0-312 Advanced Troubleshooting Practice Question
An administrator is troubleshooting a Citrix Virtual Apps and Desktops 7 environment where users report that their sessions are randomly disconnecting. The administrator suspects that the issue is related to the HDX Adaptive Transport settings. Which policy setting should the administrator verify to ensure that HDX Adaptive Transport is enabled and functioning correctly?
⚠ Common exam trap
Many candidates confuse Session Reliability or Gateway protocol with HDX Adaptive Transport, which are separate features that address different aspects of session connectivity.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
HDX Adaptive Transport
To troubleshoot random disconnections potentially linked to HDX Adaptive Transport, the administrator must verify the HDX Adaptive Transport policy setting. This policy determines whether adaptive transport is off, preferred, or diagnostic. Ensuring it is correctly configured helps maintain stable sessions, as incorrect settings can lead to transport-related disconnects.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
HDX Adaptive Transport
Why this is correct
The HDX Adaptive Transport policy setting controls whether adaptive transport (using EDT) is enabled. If set to Preferred or Diagnostic, it can affect session stability. Verifying this setting ensures that the transport mode is correctly configured, which is crucial for troubleshooting random disconnections potentially caused by transport issues.
- ✗
Citrix Gateway protocol
Why it's wrong here
The Citrix Gateway protocol setting determines the protocol used for Gateway connections (e.g., SSL, DTLS). While it can impact connectivity, it is not the primary policy for HDX Adaptive Transport. Random disconnections might be related to Gateway, but the question specifically asks about HDX Adaptive Transport, so this is not the correct setting to verify.
- ✗
HDX Adaptive Transport (legacy)
Why it's wrong here
There is no policy named 'HDX Adaptive Transport (legacy)' in Citrix Virtual Apps and Desktops 7. This is a fictitious setting. The correct policy is simply 'HDX Adaptive Transport'. Choosing this would indicate a misunderstanding of the available policies.
- ✗
Session reliability
Why it's wrong here
Session Reliability helps maintain sessions during network interruptions by buffering data, but it does not control HDX Adaptive Transport. Enabling Session Reliability can mask disconnections, but it is not the setting that governs adaptive transport behavior. The administrator should focus on the transport policy itself.
