As Cisco will be updating its syllabus and exam format by Feb 2020, we highly recommend our prospective students to complete their CCIE certification track before syllabus change.
Traditionally we have seen that it is the easiest time to clear CCIE before major format change: Exams formats are mature and unlikely to undergo any major revisions.
And there is further good news for those who take the CCIE R&S lab exam before it changes!
If you complete the entire CCIE Routing and Switching certification before February 24, then on February 24, you’ll automatically receive the new CCIE Enterprise Infrastructure v1.0 certification, which can be maintained as per new recertification guidelines, and you will also receive the Cisco Certified Specialist - Enterprise Core certification.
