* Definition of Elevation of Privilege Attack:
* This attack occurs when an attacker exploits vulnerabilities in systems to escalate their permissions beyond what they are authorized for, gaining access to sensitive data or control over the system.
* Example in the Scenario:
* The attacker uses a guest account, a low-privilege account, to exploit a system weakness and escalate their privileges, altering user account information.
* Incorrect Options Analysis:
* A. Packet tampering: Involves altering data packets, not access rights.
* B. Spoofing: Involves impersonation, not privilege escalation.
* D. Hoaxing: Refers to deceptive scams, unrelated to access rights.

* Why Other Options Are Incorrect:
* Option B: Refers to supply chain optimization, which is unrelated to the bullwhip effect.
* Option C: Describes the maker movement, not the bullwhip effect.
* Option D: Describes the network effect, unrelated to supply chain dynamics.

In a bus topology, all devices share a single central cable (backbone). If this cable fails, the entire network becomes inoperable. This topology is simple and cost-effective but lacks redundancy.
