Cisco 400-201 Online Questions & Answers

• Question 181:

  Which statement about the BFD-BGP Multihop Client Support and cBit feature is true?

  A. BFD cBit feature replaces the BGP graceful restart and the BGP fast-failover features by keeping stale routers in the RIB when a failure occurs on the control plane.
  B. The cBit in BFD determines if the BFD session failure is independent or dependent of the control plane.
  C. BFD cBit improves the BGP convergence and response time to adjacency changes with BGP neighbors; in any event of adjacency changes, the session is deactivated in the next BGP scanning interval.
  D. BFD cBit identifies VPNv4 and VPVn6 in a multihomed to avoid purging prefixes in an event of link failure when a backup link exists and is installed already in the RIB/FIB.
  B. The cBit in BFD determines if the BFD session failure is independent or dependent of the control plane.

• Question 182:

  Which two statements are true about DPT/RPR?

  A. DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings.
  B. DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber.
  C. DPT/RPR can be deployed in the Core of the SP networks where point-to-point POS links are used to make best use of the Bandwidth.
  D. In DPT/RPR rings, data packets can be sent in one direction (downstream) and the corresponding control packets in the opposite direction (upstream), thus using both fibres concurrently to maximize bandwidth.
