Access Controls
Use this page to practise ACL questions. The most common mistake is ignoring ACL direction — an ACL applied inbound and outbound behaves very differently even with identical rules.
📅 4 days🎯 ~2 questions/day- ✓Standard versus extended ACL behaviour.
- ✓Top-down processing and the implicit deny rule.
- ✓Source, destination, protocol and port matching.

Cryptography
Use this page to practise cryptography questions. Knowing which algorithm to use in which scenario — and why — is tested more than memorising key lengths or round counts.
📅 4 days🎯 ~2 questions/day- ✓Symmetric (AES) vs asymmetric (RSA, ECC) algorithm use cases.
- ✓Hashing algorithms (SHA-256, MD5) and their integrity use cases.
- ✓Public Key Infrastructure: certificates, CAs, certificate chains.
