The CompTIA Network+ test is an internationally recognized test in the IT industry. It addresses different concerns with network practices. One of these concerns is on the order of volatility.
What Is Order of Volatility?
In networking, the order of volatility is a forensic measure that gives light to a tool’s volatility level or chances of getting compromised. It acts as a data collection strategy where you would prioritize system and network processes, applications, and devices – beginning from the most volatile to the least volatile. This manner of collection rewards you with a much better data collection.
Your knowledge on the order of volatility will determine your action regarding the security of systems and networks. A Network+ certification is proof that you are capable of handling systems and networks – in case they are deemed problematic. By taking the Network+ certification practice test, you will be increasing your odds of getting a passing mark on the actual test.
In a Network+ practice test, a question that can come up involves arranging data-containing devices in line with the order of volatility. For example, you will have to arrange swap files, backup media, and CPU cache according to their volatility levels. The first one should be the most volatile, and the last should be the least volatile.
If you follow the order of volatility, the answer to the example would be CPU cache, swap files, and backup media. Data in CPU cache has relatively high volatility because it can be overwritten when you are busy with other networking tasks. Backup media contains less volatile data (compared to data in CPU cache and swap files) because it is offline data.
Passing the CompTIA Network+ Test is a way of landing a financially rewarding career in the IT industry. A Network+ certification is equal to respect (from employers), a higher salary, and more career options. These come as no surprise since the test assesses your knowledge of management, maintenance, troubleshooting, and other foundation-level network practices.
