Naturally, students who qualify for the LPIC-1 certificate choose to remain within the same path as they strive to outmatch their competitors or carve out a niche for themselves. Sometimes they want to stay along the same path by focusing on intermediate-level certificates. At times, they wish to scale new heights by diversifying their skills through other fields. One of the best options then is the LPIC-2 or Linux Engineer that dives into the Linux kernel, capacity planning, and boot loaders at an advanced level. Another great option for forward-thinking IT geeks looking to advance is the LPIC-3, commonly referred to as the Linux Enterprise Mixed Environment certification. But this doesn’t mean that you will be short of options if you choose to focus on completely different training paths from other reputable vendors such as Oracle or Red Hat.
