How to become Google Certified Cloud Digital Leader ?
Are you just venturing onto Google Cloud , just as a novice ? Are you a leading a technical team? Then this is the foundational level certification for you!
I gave my exam mid-September 2021 and was awarded with certificate within 10 working days [ This is their normal SLA for most of Google certifications, post necessary validations]
It proves to be the learning pathway- designed to increase team’s cloud confidence to collaborate with coworkers in technical cloud roles and contribute towards informed cloud related business decisions.
Also proves to be a very good start for Cloud novice, especially those from legacy background having prejudice to get started on cloud successfully.
As it doesn’t test much on hands on knowledge, all cloud enthusiasts can get started! Here are my interpretation of suitable roles.
If you are from Azure/AWS background, this is not at all an equivalent to AZ900/ AWS Cloud Practitioner. I feel it needs a bit more deeper level understanding of GCP Ecosystem all together including their support plans, billing aspects, migration, Google APIs etc. It requires at least 2X times the learning efforts and depth of understanding.
If you are posing off saying ’n’ X GCP certified, and you can easily clear GCP CDL certification, without any preparation you may be wrong! You may still need to refer some key areas like CapEx, OpEx , TCO, Billing aspects, Shared responsibility model, GCP support plans ( Distinguish between billing support, technical support, role-based support, and enterprise support) , Compliance requirements etc..
IMO, this certification is a kind off cut through all their existing certifications basics!
Exam pattern:
Questions: 40–50(It differs)
Exam duration:
a. 90 minutes [Actual Exam time ] [ I could complete all 40 questions in 30 mins and kind of revisited some “marked for review” again for some more mins and submitted ]
b. Procedural time [ 15–30 mins — Depending on proctor availability and pre checks it may vary, Account for it and keep your family informed :)]
Registration fee: $99 [ Some companies provision vouchers- check for its availability]
Language: English
Exam format: Multiple choice and multiple select [ No negative marking, don’t leave anything unanswered]
