Cisco Interview Questions & Answers

Q: Explain eye pattern waveform, signal jitter, a BERT generator, and your networking knowledge.

A: An eye pattern overlays many signal transitions to show noise and timing margin, jitter is the timing variation of edges away from ideal, and a BERT generator sends a known bit pattern to measure the bit error rate on a link. Tie these back to how you'd validate a physical-layer interface end to end.

Answer by AI

Define each term crisply: eye diagram shows margin, jitter is edge-timing deviation, BERT measures errors against a known pattern.
Connect them to a test flow: use the eye and jitter budget to predict link quality, then confirm with a BERT run.
Ground your networking answer in a real project: what layer you tested, the tools you used, and how you isolated faults.

Q: How were you storing passwords in the database, and explain different methods used for hashing passwords?

A: Passwords should never be stored in plain text; store a salted hash instead using a slow, purpose-built algorithm like bcrypt, scrypt, or Argon2. Salting stops precomputed rainbow-table attacks and a high work factor slows brute force.

Answer by AI

State the rule first: never store plaintext, store a per-user salted hash.
Compare fast hashes (MD5, SHA-256) against slow password hashes (bcrypt, scrypt, Argon2) and explain why slow wins here.
Mention salt plus optional pepper and tuning the work factor as hardware improves.

Q: What is the difference between HTTP and HTTPS?

A: HTTP sends data in plain text over port 80, while HTTPS wraps the same protocol in TLS on port 443 so traffic is encrypted, authenticated with a certificate, and protected from tampering.

Answer by AI

HTTP is unencrypted (port 80); HTTPS adds TLS encryption (port 443).
HTTPS uses a certificate to prove server identity and negotiate keys.
Call out the benefits: confidentiality, integrity, and trust for the user.

Q: What are the different memory management techniques used in an OS, and why is memory management needed?

A: Memory management lets an OS allocate, protect, and reclaim memory across processes; common techniques include paging, segmentation, virtual memory with demand paging, and swapping. It's needed so processes stay isolated, memory is used efficiently, and programs larger than physical RAM can still run.

Answer by AI

List the core techniques: contiguous allocation, paging, segmentation, and virtual memory.
Explain why: isolation between processes, efficient use of limited RAM, and running programs bigger than physical memory.
Mention demand paging and swapping as ways to stretch available memory.
