  C. 6 seconds

  D. 15 seconds

  Correct Answer: C

  Reference: Page 3-14 of the JNCIS-ENT Routing Study Guide - "As previously mentioned, STP uses BPDUs to elect a root bridge, identify root ports for each switch, identify designated ports foreach physical LAN segment, prune specific redundant links to create a loop-free tree topology, and report and acknowledge topology changes. RSTP configuration BPDUs also function as keepalives. All RSTP bridges send configuration BPDUs every 2 seconds by default. You can alter this value, if necessary."
