Question 21

Which two impacts of adding the IP event dampening feature to a network design are true? (Choose two.)

  1. It switches traffic immediately after a link failure
  2. It improves overall network stability
  3. It speeds up link failure detection
  4. It protects against routing loops
  5. It reduces the utilization of system processing resources

Question 22

You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

  1. Choose a high minimum data rate to reduce the duty cycle.
  2. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
  3. Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
  4. Increase the number of SSIDs to load-balance the client traffic.
  5. Implement a four-channel design on 2.4 GHz to increase the number of available channels.

Question 23

Which optimal use of interface dampening on a fast convergence network design is true?

  1. when the switch hardware is faster than the debounce timer down detection
  2. when numerous adjacent flaps of very short duration occur
  3. when occasional flaps of long duration occur
  4. when the router hardware is slower than the carrier delay down detection

Question 24

A healthcare customer requested that SNMP traps must be sent over the MPLS Layer 3 VPN service. Which protocol must be enabled?

  1. syslog
  2. SNMPv3
  3. SNMPv2
  4. syslog TLS
  5. SSH
