✍️ Sample CTE Questions & Answers
1. In designing a telecom data center network, what is the primary advantage of a spine-leaf topology over a traditional three-tier (core-distribution-access) topology?
Spine-leaf ensures any server can reach any other server in exactly two hops (leaf-to-spine-to-leaf), providing consistent low latency for the east-west traffic dominant in cloud-native telecom.
2. Which type of cryptographic attack specifically targets the handshake process in TLS connections used to secure telecom management interfaces?
BEAST exploits a vulnerability in TLS 1.0's CBC mode cipher implementation during the handshake to decrypt encrypted data.
3. What is change management in CTE technology?
IT change management ensures changes are evaluated, approved, tested, and implemented in a controlled manner.
4. Which quality management tool is BEST used to identify the root cause of repeated network outages during a project?
A fishbone diagram systematically explores all possible causes of a problem by categorizing potential root causes.
5. Which security architecture principle requires that every access request in a telecom network be authenticated and authorized regardless of network location?
Zero Trust Architecture operates on 'never trust, always verify,' eliminating implicit trust based on network location or IP address.
6. Which protocol is used by network elements in a telecom architecture to export flow-level data for traffic analysis and capacity planning?
NetFlow (and its standardized form IPFIX) exports metadata about IP flows from routers and switches, enabling detailed traffic analysis and capacity planning.
