Pre Exam Notes
- Kryterion Sentinel software (Windows/Mac) installation requires administrator rights
- Kyterion system check - do this at least a day before to be on the safe side
- No breaks during two hour exam
- Do the practice exam to build some confidence
- (Try and) get a good nights sleep before the exam
- The exam is multiple choice, so work out the wrong answers first!!
Post Exam Notes
- Online Kryterion exams still suck - Admin permissions for the entire machine, seriously?
- Waiting for confirmation of the exam result is now 10 days!!
- Swag continues to be "Out of stock"
- Still no feedback beyond pass/fail (Grrr!)
- 50 Questions
Google Cloud do not indicate the pass mark for the exam, but I would assume its somewhere greater than 70%.
I typically aim to be confident on 80% (i.e. 40/50) of the questions. The table below shows the spectrum of scores, but in simple terms you just need to be on the right side of 80% to be comfortable.
| Percent | 10% | 20% | 30% | 40% | 50% | 60% | 70% | 80% | 90% | 100% |
|---|---|---|---|---|---|---|---|---|---|---|
| Correct | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
| Incorrect | 45 | 40 | 35 | 30 | 25 | 20 | 15 | 10 | 5 | 0 |
Depending on what type of person you are the above calculation may be of some use.
I think about the exam result in terms of how many answers I can afford to NOT know.
Once you have read the exam overview, it should be clear this exam is meant to cover the majority of network products on GCP.
- IAM
- VPC
- Cloud NAT
- Firewalls
- Cloud Armor
- Cloud DNS
- Load Balancer
- Hybrid Network
- Google Kubernetes Engine
- Cloud CDN
- SSH Key Management
- Cloud Router
This exam is a good complement to the Security Engineer exam. If you plan to take this exam, note there is some overlap between the subject material. Overall the exam is pretty tough as it requires a wide amount of knowledge. Understanding the defaults and how particular products are used will be super helpful in taking this exam.
Training Material
If you have got this far, I havent put you off taking the exam. Personally I found this exam pretty challenging. It covers a lot of ground and I took all the time to complete the exam.
Also try and prioritise the type of material that works best for you!
| Source | Type | Description | Rating |
|---|---|---|---|
| Coursera | Course | Google Cloud Professional Network Engineer | 4/5 |
| Pluralsight | Course | Google Cloud Professional Network Engineer | 4/5 |
For this exam in particular, I highly recommend hands-on experience. The creation of VPCs, knowing about default routing and how Firewall logging/rules work are essential information for this exam.
Best of luck!
