Resource exhaustion occurs when a system runs out of resources such as memory, CPU, disk space, or network bandwidth due to excessive demand or poor management1. In this case, the server statistics show that the CPU usage is 100%, the memory usage is 99%, and the disk usage is 98%, indicating that the system is suffering from resource exhaustion. This can affect the performance and availability of the system and its applications. A race condition (A) is a condition where the system's behavior depends on the sequence or timing of other uncontrollable events2. Privilege escalation (B) is a situation where an attacker gains unauthorized access to higher privileges or permissions on a system3. VM escape (D) is a technique where an attacker breaks out of a virtual machine and interacts with the host operating system.

A security information and event management (SIEM) system is a tool that collects and analyzes log data from various sources and provides alerts and reports on security incidents and events. A security analyst can create a custom rule on a SIEM system to automate the incident response process for malware infections. For example, the analyst can create a rule that triggers an alert email when the SIEM system detects logs that match the criteria of malware infection, such as process name, file name, file hash, etc. The alert email can be sent within 30 minutes or any other desired time frame. The other options are not suitable or sufficient for this purpose.

A hot site is always ready to take over the primary site's workload, so wouldn't it be more cost-effective in the long run? Additionally, a hot site would provide faster recovery times and better protection against data loss compared to a warm site.
