Federation is an access management concept that allows users to authenticate once and access multiple resources or services across different domains or organizations. Federation relies on a trusted third party that stores the user’s credentials and provides them to the requested resources or services without exposing them. Password complexity is a security measure that requires users to create passwords that meet certain criteria, such as length, character types, and uniqueness. Password complexity can help prevent brute-force attacks, password guessing, and credential stuffing by making passwords harder to crack or guess. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308-309 and 312-313 1

ARP poisoning(also known as ARP spoofing) is a basicman-in-the-middle (MITM)attack that involves sending fake ARP responses to redirect traffic. This technique isnot sophisticatedand can be easily executed using freely available tools like Cain & Abel, Ettercap, or Wireshark.

Such attacks are often attempted byunskilled attackers (script kiddies)testing their abilities, especially in environments like schools. The term“unskilled attacker”fits best here, as credential stuffing and DMARC are unrelated to ARP poisoning.

A VPN (Virtual Private Network) is a secure method to provide employees with remote access to a company's network. It encrypts data, protecting it from interception and ensuring secure communication between the user and the internal network.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.
