She suggested a great way to prepare

My aunt lives in Serbia. She teaches college students. I went there once. I impress by her method of teaching. She gives practical example to students. While having tea, she suggested me to take up GCP-PCNE certification exam. I asked how to practice. She tells through Google Professional Cloud Network Engineer practical exposure online. I can study from any place i want and even while i was travelling. I passed and thank her from my heart because she propelled my future.
