Explanation:

Before taking any action, the SOC analyst should first verify if the Indicators of Compromise (IoC) and Tactics, Techniques, and Procedures (TTPs) reported are relevant to the organization's environment. This involves checking if the vulnerable application or version is actually in use. As per CompTIA's CySA+ guidelines, relevance verification helps in prioritizing resources and response actions effectively, ensuring that time is not wasted on threats that do not impact the organization. Options A, B, and D are important subsequent steps if the threat is deemed relevant.
