A network with five switches has been configured to run Rapid Spanning Tree Protocol (RSTP) with default settings. How many seconds does it take to detect a failure between two neighboring switches?

  1. 2 seconds

  2. 3 seconds

  3. 6 seconds

  4. 15 seconds

Answer: C

Reference: Page 3-14 of the JNCIS-ENT Routing Study Guide – quot;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.quot;

Question No: 38 – (Topic 1)

Which side of the OSPF router initiates the database description exchange?

  1. the side with the higher IP address

  4. the side with the higher uptime

Answer: B

Question No: 39 – (Topic 1)

    area { nssa { default-lsa {

    default-metric 1;

    metric-type 1;







  2. protocols { ospf {

    area { nssa {






  3. protocols {

    ospf {

    area { stub summaries;




  4. protocols { ospf {
