✍️ Sample CCNP Questions & Answers
1. What is the role of CSPF (Constrained Shortest Path First) in MPLS Traffic Engineering?
CSPF uses the Traffic Engineering Database (TED) populated by IGP extensions to compute a constrained path for TE tunnels that meets bandwidth, affinity, and other user-defined constraints.
2. In which OSI layer should devices in the distribution layer typically operate?
Explanation: Devices in the distribution layer typically operate at Layer 3 of the OSI model. Layer 3, also known as the network layer, is responsible for routing packets across different networks. The distribution layer connects different LANs or VLANs and performs functions like routing, filtering, and policy-based traffic control. It ensures that packets are delivered to the correct destination network by examining IP addresses and making routing decisions. Therefore, devices in the distribution layer primarily operate at Layer 3 to facilitate inter-network communication.
3. In a properly designed hierarchical network, a broadcast from one PC is confined to what?
Explanation: In a properly designed hierarchical network, a broadcast from one PC is confined to one switch block. This means that the broadcast traffic is limited to the specific area or segment of the network where the PC and the corresponding switch block are located. It does not propagate to the entire campus network, which helps to minimize network congestion and improve overall network performance.
4. What is the purpose of access controls in Cisco Certified Network Professional network security?
Access controls restrict system and data access to authorized personnel, protecting sensitive information from unauthorized viewing, modification, or deletion.
5. In MPLS TE, which protocol is used to signal and establish label-switched paths (LSPs)?
RSVP-TE (Resource Reservation Protocol - Traffic Engineering) is the signaling protocol used to establish MPLS-TE tunnels, reserving bandwidth and specifying explicit paths.
6. What does system integration mean in Cisco Certified Network Professional wireless networking?
System integration connects different technology systems to work together seamlessly, enabling data sharing, reducing redundancy, and improving workflow efficiency across the organization.
