This SY0-701 practice question tests your understanding of general security concepts. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Match each cryptographic action to the most appropriate use case.
Drag a concept onto its matching description — or click a concept then click the description.
Protect the data if the laptop is stolen.
Check that the file was not changed during download.
Make identical passwords produce different hash values.
Confirm the file came from the expected sender and stayed intact.
Replace an encryption key on a planned schedule.
Correct answer & explanation
Encryption ensures confidentiality, hashing ensures integrity, digital signatures provide authentication and non-repudiation, key exchange enables secure key distribution, certificate signing establishes trust, and random numbers are essential for key generation.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SY0-701 NAT questions on configuration and troubleshooting.
