DevAsc and DevNet2020
Today I passed the Cisco Certified DevNet Associate DEVASC 200-901 exam.
Here’s a quick note about my experience.
Then some $bigProjects started, summertime priority went to outdoor activities after months of lockdown, other $bigProjects sucked all my energy and the end of the year was approaching fast.
Network automation is the perfect mix of two of my passions: networking and coding, I couldn’t miss this opportunity!
I took advantage of the O'Reilly Learning subscription and based my studies on the Cisco Certified DevNet Associate DEVASC 200-901 Official Cert Guide. .
for some personal projects so the Python part of the exam preparation was just a light review, same for the networking chapters.
NETCONF and RESTCONF are pretty new to me, I don’t use them in my current job. I did some exercises with ncclient and curl to grasp the basics and learn enough to cover the topics of the exam.
As earlier this year I did the exam remotely from the kid’s room. The experience was positive again, I had no issues with the software setup. Drinks are permitted but gum, smoking and food are not.
The webcam must stream a video for the whole duration of the exam. The bandwidth depends on the quality of the video, HD is enough to comply the exam requirements. If you have a 4k/FHD cam just change the settings to avoid any issue.
I’ve found the exam fair, as usual my main concern was related to the wording of some questions.
I scored quite good (965/1000) probably thanks to my experience with Python, API and automation in general.
This was the traffic on my Internet connection, not that much. I advise to reduce the resolution of the video feed, the proctor probably doesn’t need a 4k video stream, HD should be enough.
Cisco DevNet is the best thing that could happen to the entire networking industry
and according to my Twitter echo chamber many Network Engineers are writing code to create new tools, automate some tasks or glue together different products using API.
While this will not be a career change for me I consider coding an important skill to complete my profile.
Stay tuned for my next projects!
