"Network+ security questions test whether you can match an attack description to its name and identify the appropriate countermeasure. The exam rarely goes deeper, you don't need to know how to execute ARP poisoning, just what it is, how it works conceptually, and that dynamic ARP inspection on a switch prevents it." - Darril Gibson, CompTIA author and exam prep instructor --- "Security+ questions frequently embed the answer in understanding basic networking. 'A packet is captured with a source IP of 192.168.1.1 and destination of 8.8.8.8 on port 53. What type of traffic is this?' You need to know DNS uses port 53, which is Network+ content. Security+ doesn't re-teach port numbers, it assumes them." - Darril Gibson, CompTIA Network+ and Security+ author
Network+ security questions test whether you can match an attack description to its name and identify the appropriate countermeasure. The exam rarely goes deeper: you do not need to know how to execute ARP poisoning, just what it is, how it works conceptually, and that dynamic ARP inspection on a switch prevents it. --- Security+ questions frequently embed the answer in understanding basic networking. Consider a packet captured with a source IP of 192.168.1.1 and destination of 8.8.8.8 on port 53: recognizing this as DNS traffic requires knowing that DNS uses port 53, which is Network+ content. Security+ does not re-teach port numbers; it assumes them.
