Hi Kristina,
Thank you for contacting the Microsoft Community.
I recognize that you’ve encountered challenges during your exam, and I fully comprehend the significance of passing this test for you. Allow me to assist you by providing all the essential information you need.
As per the Unscheduled Breaks on exam FAQs, once a break is launched, you will not be able to return to the questions that you viewed before the break even if they are unanswered or marked for review. This also applies if you take breaks during case studies; you won’t be able to revisit any question that was seen before the break.
Meanwhile, since you've mentioned that you've encountered a technical error during the lab questions, please be advised that for any technical issue before, during, and after the exam, this should be coordinated with your proctor. Since you've mentioned that you have reached out to your proctor, and were advised that there's no issue, kindly reach out to Pearson Vue for immediate assistance for possible options and recommendations. You may also inform them of the situation that you have, as they have the appropriate tool to modify your appointment. Kindly refer to their contact information below:
Peason VUE: Customer service :: Microsoft :: Pearson VUE (please know that their response usually takes 3–5 business days)
Should you already have an open case with them and still require further assistance, kindly provide me with the Case ID along with the following needed information through the private message I initiated, so I can follow up on your behalf.
For future reference, if in any case your lab launches with a blank white screen, try opening a new tab and navigating to https://portal.azure.com. Opening this new tab will resolve the issue most of the time. You may visit Assessment lab frequently asked questions | Microsoft Learn, for more detailed information.
In addition, if you run into any other issues with labs, please complete the Exam item challenge process. Although we won’t be able to provide a specific explanation for your experience, our investigation will help us identify root causes and identify solutions that will improve the experience for everyone.
Moreover, with those experiences that you have mentioned, you can also submit your personal feedback through Pearson Vue. You may refer to Feedback and complaints | Pearson qualifications.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages. Thank you.
Kind Regards,
