Which eval operator concatenates a string and a number in Splunk?
When using the eval command, which of these characters can be used to concatenate a string and a number into a single value?
Community Votes
60% of anonymous learners picked answer D. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The exam tests the specific eval operator behavior: the period (.) concatenates strings and numbers, while the plus (+) cannot mix types for concatenation.
In Splunk's eval command, the period (.) operator concatenates a string and a number into a single value. Community votes favor D, but some misidentify the plus (+) operator, which actually only concatenates two strings or adds two numbers.
Choosing C. Plus (+) is a common mistake because many programming languages use + for concatenation, but Splunk's eval plus only concatenates two strings or adds two numbers; it does not accept a string and number mix.

Expert Analysis
Why the Answer Is Correct
The correct answer is D. Splunk's eval command uses the period (.) operator specifically for concatenating a string and a number. This is documented in the official eval operators table. As one commenter notes, "The period ( . ) operator concatenates both strings and numbers. Numbers are concatenated in their string represented form." This means the result is always a string.
Why the Other Options Are Wrong
A (~) is not a valid eval operator for concatenation. B (&) is also not used for concatenation in Splunk. C (+) is a common trap: it concatenates two strings or adds two numbers, but it cannot mix a string and a number. One commenter incorrectly claimed C is correct, but they overlooked the distinction between string-string concatenation and string-number concatenation.
Community Comment Notes
Several commenters correctly identified D with supporting explanations. Comment 1 states that the period concatenates both strings and numbers, while the plus concatenates string with string or number with number. Comment 3 provides a direct link to the official Splunk documentation. Comment 5, which argues for C, is misleading and reflects a misunderstanding of eval operator rules in Splunk.

Exam Strategy
Memorize Splunk's eval operator table: '+' is for addition or string-string concatenation, while '.' is for string-number concatenation. On the exam, read the prompt carefully to see whether they ask for 'string and number' (use '.') or 'string and string' (use '+').
