Splunk Enterprise Certified Admin Practice Test

Can the wildcards '...' and '*' be used in the whitelist and blacklist?

1. Yes

2. No

3. Only in certain contexts

4. Only in regex patterns

The correct answer is: No

The use of wildcards in the context of whitelists and blacklists in Splunk is specific, and the statement that wildcards cannot be used is correct. Generally, whitelists and blacklists are meant to define clear and precise conditions under which data is included or excluded from processing. The purpose of these lists is to provide stringent control over what data is permitted or denied, and allowing wildcards could lead to ambiguities and unintended inclusions or exclusions. In practice, using wildcards like '...' and '*' could create challenges in managing data effectively and could compromise the security and integrity of the data processing. Therefore, it is vital to adhere to the standard procedure of explicitly defining the paths, sources, or data attributes without resorting to wildcards in these particular configurations. To summarize, the correct choice aligns with the intended function of whitelists and blacklists in Splunk, emphasizing precision and eliminating the potential for error that wildcards could introduce.
