Here is some facts about this new section:

• You must complete this portion of the exam before you start the traditional configuration portion.
• You have a total of 30 minutes to complete this section, you may finish early if you like and immediately begin your configuration section.
• You will receive 4 questions via the computer and you must provide short answers using the computer interface. The questions are not oral in nature. Typical responses require 4 to 5 words at most.
• Spelling and/or grammar does not count against you.
• The questions are manually graded by a proctor. If you purchase an exam re-read, they will re-grade your question responses.
• You may not return to the short answer questions once you have begun the configuration portion of the lab exam.
• You will not receive a score when you complete this section, but you must pass this portion to pass the CCIE. You will receive your score in the open-ended section if you fail the exam. The score is reported as 0% or 100% (pass or fail). You may only miss one question in the section in order to pass.
• Most students finish the 4 to 5 questions in approximately 12 minutes.
• The configuration portion of the exam has been reduced to accommodate this initial 30 minutes.
• You still have a total of 8 hours that makeup the open-ended questions and the configuration portion.
• You may not access the DOC-CD to answer these questions.
