Which of the following is a key role of a vault administrator?

A vault administrator plays a critical role in overseeing the security and integrity of the vault, which is responsible for storing sensitive credentials, secrets, and other protected data. Auditing user activities is essential in this role as it helps to ensure compliance with security policies and regulations, detects any unauthorized access or anomalies, and assesses the overall usage of the vault system. This function allows the administrator to identify potential security threats and take necessary actions to mitigate risks, thereby protecting the organization’s sensitive information.

While conducting training sessions and managing external vendor integrations do have their importance in the broader context of information security and organizational operations, they do not specifically fall under the primary responsibilities of a vault administrator. Preparing marketing strategies is unrelated to the technical and security-focused role of a vault administrator, as it pertains more to business development and public relations. Thus, the auditing of user activities stands out as a key role that directly aligns with the vault administrator's primary functions in maintaining security and compliance within the organization.
