事隔兩年多的時間，Zorloo 為 Ztella 推出第二代了，名為 Ztella II。接駁訊源的一端依舊使用 USB Type-C，做到一插即用，可連接手機、iPad 或個人電腦等等；最大分別是接合耳機的一端，改用上 4.4mm 平衡輸出插口，而輸出功率比上代增強了不少，很容易就可感受得到強大的驅動力。
You cannot pass the new CCNA by just "winging it" with random YouTube videos. You need structured, accurate, concise notes. Jeremy’s IT Lab PDF is the gold standard because it strips away the Cisco "bureaucratic language" and gives you exactly what you need to pass the exam and work on real equipment.
Stop reading this post. Go to Jeremy’s Patreon. Buy the PDF. Print Day 1 (Network Devices) and Day 2 (OSI Model). Start studying tonight.
If you are studying for the Cisco CCNA 200-301 certification, you have probably heard the name whispered in Discord servers, Reddit threads (r/CCNA), and YouTube comments like a sacred mantra.
Good luck on your CCNA journey. See you on the other side of the exam. Have you used Jeremy’s IT Lab notes? Drop a comment below with your pass/fail story!
Open Packet Tracer. Do the lab. Here is the secret: Don't look at the PDF while labbing. Only check the PDF after you get an error.
