A university with remote campuses, which all use different service providers, loses Internet connectivity across all locations. After a few minutes, Internet and VoIP services are restored, only to go offline again at random intervals, typically within four minutes of services being restored. Outages continue throughout the day, impacting all inbound and outbound connections and services. Services that are limited to the local LAN or WiFi network are not impacted, but all WAN and VoIP services are affected. Later that day, the edge-router manufacturer releases a CVE outlining the ability of an attacker to exploit the SIP protocol handling on devices, leading to resource exhaustion and system reloads. Which of the following BEST describe this type of attack? (Choose two.)
A) DoS
B) SSL stripping
C) Memory leak
D) Race condition
E) Shimming
F) Refactoring

DoS (Denial of Service) attacks are designed to overwhelm a system with excessive traffic, causing it to become unavailable to legitimate users. In this case, the attacker exploited a vulnerability in the SIP protocol handling on the edge routers, leading to resource exhaustion and system reloads, resulting in repeated outages.Race conditions occur when multiple threads or processes attempt to access the same resource at the same time, potentially leading to unexpected or incorrect results. In this case, the attacker may have exploited a race condition in the SIP protocol handling, causing the system to reload repeatedly.
