Yes. Your exam session remains open for 7 days from the exact date and time in which the exam was started. Most exams will resume from the same question and the same time remaining if resumed on the very computer in which it was started. To resume an exam, launch it as you would normally but choose the exam marked "in-progress". Should you exceed the 7 days you must begin the exam again with a new voucher, license, or piece of inventory - no extensions can be granted.
