IS network? (Choose two.)

  • A. It performs a similar role to the designated router (DR) in OSPF.
  • B. It is not allowed to send any PDUs on a designated intermediate system (DIS).
  • C. A backup DIS is not elected.

  • B. It will be routed to 10.17.0.1.
  • C. It will be routed to 10.32.0.1.

Answer : C

Given that ge-0/1/1 is set up as a trunk port, which command set will NOT successfully set the trunk to carry VLANs 10 and 11?

  • A. set interfaces ge-0/1/1.0 family ethernet-switching vlan members [Vlan10 Vlan11]
  • B. set interfaces ge-0/1/1.0 family ethernet-switching vlan members Vlan10 members Vlan11
  • C. set interfaces ge-0/1/1.0 family ethernet-switching vlan members Vlan10,Vlan11
  • D. set interfaces ge-0/1/1.0 family ethernet-switching vlan members Vlan10set interfaces ge-0/1/1.0 family ethernet-switching vlan members Vlan11


Answer : C

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?

  • A. 2 seconds
  • B. 3 seconds
  • C. 6 seconds
  • D. 15 seconds


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."

  • C. the side with the higher priority
  • D. the side with the higher uptime


Answer : B

Which configuration summarizes external routes in the 172.16.0.0/22 range into a single prefix on an ABR for Area 1?

  • B. protocols { ospf { area 0.0.0.1 { nssa { area-range 172.16.0.0/22; } } } }
  • C. protocols { ospf { area 0.0.0.1 { stub summaries; } } }
  • D. protocols { ospf { area 0.0.0.1 { nssa; area-range 172.16.0.0/22 restrict; } } }
