Dynamic ARP Inspection a security feature that helps mitigate attacks that use spoofed Address Resolution Protocol (ARP) packets. Dynamic ARP inspection works by verifying that all ARP traffic on a network is valid. Invalid ARP packets are dropped, which helps protect your network from attacks that use forged or spoofed source IP addresses.

The Standard Template Library (STL) is one of the most essential features of C++. It has very much grown in recent years. Basically, the Standard Template Library provides templatized, general-purpose classes as well as methods. These classes and functions/methods implement several popular and most commonly used algorithms as well as data structures.
The environment in which your code runs is imperfect: users will provide invalid inputs, external systems will go down, and your code and other code around it will often contain some number of bugs. Given this, errors are inevitable; things can and will go wrong, and as a result you can’t write robust and reliable code without thinking carefully about error cases.
