1Y0-312 Advanced Troubleshooting Practice Question
Which THREE items are required to successfully collect a complete CDF trace from a VDA for troubleshooting purposes? (Choose three.)
⚠ Common exam trap
Candidates often overlook the necessity of synchronized system clocks, assuming that independent log files from different components can be correlated solely by timestamps without NTP.
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
✓
Synchronized system clocks
Collecting a valid CDF trace requires synchronized timing, the correct selection of trace modules, and a defined output destination. Without these, the resulting log files will be either incomplete, impossible to correlate with events from other components, or too large to manage. Expert troubleshooting relies on clean, filtered data that covers the specific timeframe of the issue being analyzed across the infrastructure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Synchronized system clocks
Why this is correct
Synchronized time is critical for correlating logs across different servers. If the clocks between the VDA and the Delivery Controller are drifting, matching a client request to a server response becomes extremely difficult. NTP should be used to ensure that all infrastructure components operate on the exact same time.
- ✗
Standard User privileges
Why it's wrong here
CDF tracing involves low-level hooks into Windows services and system components, which requires administrative or elevated privileges. A standard user account will lack the necessary permissions to start the trace, capture system-wide events, or write files to protected system directories, making it impossible to perform the requested troubleshooting task.
- ✓
Selected trace modules
Why this is correct
Selecting specific modules (like BrokerAgent or VDA) reduces noise in the log file, allowing the administrator to focus on relevant data. Capturing everything can overwhelm the system and generate massive files, making it hard to find the specific error entries required to isolate the root cause of the problem.
- ✓
A defined file output path
Why this is correct
A defined output path is essential for storing the trace data. The administrator must ensure that the target disk has sufficient space, as high-level tracing can generate very large output files quickly. Without a defined path, the trace tool cannot effectively capture and save the diagnostic data for analysis.
- ✗
An active user session
Why it's wrong here
While a session is often the subject of a trace, it is not a technical requirement to have an active session running when starting the trace. Many issues, such as VDA registration failures or service startup errors, can be traced without a user session being established at all.
