Which way can most effectively improve BGP convergence in the event that a point-to-point link, over which an EBGP session is running, fails?

  1. Use BGP multichip
  2. Configure EBGP fast external fall over
  3. Enable BGP graceful restart
  4. Reduce the keep alive timer to the minimum value allowed

Answer(s): B



You are the Cisco Network Designer in P4S. In your company site, a NAS is both physically and logically in the traffic path. The NAS identifies clients solely based on their MAC addresses. In which access mode has this NAS been configured to operate?

  1. Layer 2 mode
  2. Layer 2 Edge mode
  3. Layer 3 mode
  4. Layer 3 In-Band mode

Answer(s): A



According to the following exhibit, company 1 contains two autonomous systems (AS1 and AS2) connected via ISP A, which has an AS number of 100. Router P4S-RB and Router P4S-RC are advertising an aggregate of X.X.X.0/23 so that AS1 is able to reach the two server farms. The two links from AS2 are not being used efficiently. How can AS2 use both of the links coming into it?

  1. Create another link between Router P4S-RA in AS1 and ISP A
  2. Configure two static routes in Router P4S-RA for X.X.X.0/23 pointing to Router P4S-RB and Router P4S-RC
  3. Advertise each X.X.X.0/24 independently from Router P4S-RB and Router P4S-RC
  4. Configure iBGP between Router P4S-RB and Router P4S-RC to load-share traffic once it reaches AS2

Answer(s): C



Study the exhibit carefully. In this network, configure P4S-R1, P4S-R2, and P4S-R3 in EIGRP AS100, and configure P4S-R3 and P4S-R4 in EIGRP AS 200. P4S-R3 is configured to redistribute between the two EIGRP autonomous systems. Then, P4S-R1 loses its connection to 192.168.1.0/24. Which source will P4S-R4 receive a query from, or if it will not receive a query, why not?

  1. P4S-R4 will not receive any queries for 192.168.1.0/24, because it's not in the same autonomous system as P4S-R1 or 192.168.1.0/24.
  2. P4S-R4 will not receive any queries for 192.168.1.0/24. P4S-R1 will not generate any queries for this destination because there are no other paths available in the network.
  3. P4S-R4 will receive one query for 192.168.1.0/24 from P4S-R1 itself, since P4S-R1 has lost its connection to the destination.
  4. P4S-R4 will receive one query. Once AS100 has converged, P4S-R3 will have no route to 192.168.1.0/24, so it will initiate a query into AS 200.
