Exam PT0-002 topic 1 question 181 discussion

Answer: D. Prints each DNS query result already stored in variable b Explanation: Line 3 of the script creates a packet and stores it in the variable 'a'. Line 4 sends the packet and stores the results in the variable 'b'. Lines 5 and 6 loop through the results stored in 'b' and print each DNS query result stored in that variable.

prints a specific attribute (.rdata) of the answer

I am as certain as I can be (short of actually executing the code) that B is the best fit among the provided options. Here's a recap of why the other options are definitively wrong: A: The query is for www.comptia.org, not for SOA information of the zone. C: The script loops through the answer records and prints the data within them, not the count of the results. D: The script doesn't print the entire response object stored in b; it iterates through and prints a specific attribute (.rdata) of the answer records within that response. Option B, while using the slightly imprecise phrase "raw data output," correctly identifies that a single DNS query is performed for www.comptia.org, and the subsequent lines print some of the data received in the response (specifically the rdata of the answer records).
