Free GPYC: GIAC Python Coder Exam Questions and Answers
GIAC Python Coder is exam GPYC, part of GIAC certification from GIAC, the affiliated certification body to SANS Institute. GIAC exams are open book but hard copy only, run two to five hours, and many include CyberLive tasks performed on a live virtual machine rather than answered from memory. Codes are letters rather than numbers — G plus the subject for practitioner certifications, GX- for the Applied Knowledge tier.

Question #1
A script builds a binary packet header with the following code: import struct print(struct.pack(">HB", 513, 7)) What is the output?
Correct answer: C
Explanation
The > prefix selects big-endian byte order with standard sizes and no padding. H packs 513 (0x0201) into two bytes, most significant first, giving \x02\x01, and B adds the single byte \x07. Little-endian would reverse the first two bytes, and padding is only added with native alignment.

Question #2
What is the output of the following code? import hashlib h = hashlib.sha1(b"test") print(len(h.digest()), len(h.hexdigest()))
Correct answer: A
Explanation
SHA-1 produces a 20-byte digest, so digest() returns 20 bytes. hexdigest() writes each byte as two hexadecimal characters, giving a 40-character string. The value 160 is the digest size in bits, not bytes.

Question #3
A script accepts a hostname from a user and must ping it once. Which call avoids shell command injection if host contains a value such as "8.8.8.8; cat /etc/passwd"?
Correct answer: C
Explanation
Passing an argument list without shell=True runs ping directly, so the whole value of host is delivered as one argument and the semicolon has no special meaning. The other calls hand a single string to a shell, which interprets the semicolon and runs the second command. An f-string does not sanitize input.

Question #4
What is the output of the following code? import re s = "<a><b><c>" print(len(re.findall(r"<.+>", s)), len(re.findall(r"<.+?>", s)))
Correct answer: B
Explanation
The pattern <.+> is greedy, so .+ consumes as much as possible and a single match spans the entire string. The pattern <.+?> is non-greedy and stops at the first closing bracket, producing three separate matches: <a>, <b> and <c>.

Question #5
What is the output of the following code in Python 3? data = b"AB" print(data[0], data[0:1])
Correct answer: D
Explanation
Indexing a bytes object returns an int, so data[0] is 65. Slicing returns a bytes object, so data[0:1] prints as b'A'. This difference is a common source of bugs when code written for Python 2 is ported.

Question #6
What is the output of the following code? import json rec = json.loads('{"port": 22, "open": true, "banner": null}') print(rec["open"], rec["banner"], type(rec["port"]).__name__)
Correct answer: C
Explanation
json.loads maps JSON true to Python True, null to None and a JSON number without a decimal point to int. Printing the objects shows the Python spellings, not the JSON ones.

Question #7
A port scanner calls s.connect_ex(("192.0.2.10", 443)) on a TCP socket. The target host is reachable but actively refuses the connection because nothing is listening on the port. What does the call do?
Correct answer: B
Explanation
connect_ex behaves like connect but reports failures from the underlying system call by returning the errno value instead of raising an exception. It returns 0 only when the connection succeeds, which makes it convenient for scanners.

Question #8
In Python 3, what does a call to sock.recv(1024) on a connected TCP socket return?
Correct answer: D
Explanation
recv() returns a bytes object, and the number is only a maximum. Fewer bytes may arrive in one call, so code must loop if it needs a full message. Decoding to str requires an explicit decode() call.

Question #9
What does len(hashlib.sha256(b"test").hexdigest()) return?
Correct answer: C
Explanation
SHA-256 produces a 256-bit digest, which is 32 bytes. hexdigest() writes each byte as two hexadecimal characters, giving 64 characters. 32 would be the length of digest(), and 256 is the size in bits.

Question #10
What is the output of the following code? counts = {"10.0.0.5": 7, "10.0.0.9": 12, "10.0.0.2": 7} top = sorted(counts.items(), key=lambda kv: kv[1], reverse=True)[0] print(top)
Correct answer: C
Explanation
items() yields (key, value) tuples, and the key function sorts them by the count in descending order. Index 0 is the whole tuple with the highest count, so it prints as a tuple. Only top[0] would give the bare address string.
