The requirement here is to construct a SQL query that retrieves logs with specific fields, namely "Source IP" and "Destination Port," for entries where the source IP address matches 10.0.1.10. The correct syntax is essential for selecting, filtering, ordering, and grouping the results as shown in the expected outcome.
Analysis of the Options:
Option A Explanation:
SELECT srcip AS "Source IP", dstport AS "Destination Port": This syntax selects srcip and dstport, renaming them to "Source IP" and "Destination Port" respectively in the output.
FROM $log: Specifies the log table as the data source.
WHERE $filter AND srcip = '10.0.1.10': This line filters logs to only include entries with srcip equal to 10.0.1.10.
ORDER BY dstport DESC: Orders the results in descending order by dstport.
GROUP BY srcip, dstport: Groups results by srcip and dstport, which is valid SQL syntax.
This option meets all the requirements to get the expected results accurately.
Option B Explanation:
WHERE $filter AND Source IP != '10.0.1.10': Uses != instead of =. This would exclude logs from the specified IP 10.0.1.10, which is contrary to the expected result.
Option C Explanation:
The ORDER BY clause appears before the FROM clause, which is incorrect syntax. SQL requires the FROM clause to follow the SELECT clause directly.
Option D Explanation:
The GROUP BY clause should follow the FROM clause. However, here, it’s located after WHERE, making it syntactically incorrect.
Conclusion:
Correct Answer: A. Option A
This option aligns perfectly with standard SQL syntax and filters correctly for srcip = '10.0.1.10', while ordering and grouping as required.
