  • B: RMON mode (based on RMONv1 and RMONv2 data)
  • C: passive mode (based on NetFlow data)
  • D: active mode (based on Cisco IP SLAprobes)
  • E: fast mode (based on Cisco IP SLA probes)

Refer to the exhibit. For which reason could the statistics for IP SLA operation 1 be unknown?

  • A: The IP SLA schedule is missing.
  • B: The ICMP echoes were lost in transit.
  • C: The Type of Service parameter is configured incorrectly.
  • D: The Operation Frequency value is the same as the Operation Timeout value.
  • E: Data verification has been disabled.

Correct Answer: A




Question 4

An IP SLA fails to generate statistics. How can you fix the problem?

  • A: Add the debug ip sla error command to the router configuration.
  • B: Add the debug ip sla trace command to the router configuration.
  • C: Reload the router configuration.
  • D: Remove the ip sla schedule statement from the router configuration and re-enter it.
  • E: Add the verify-data command to the router configuration.

Correct Answer: E




Question 5

Refer to the exhibit. 

  

Which two statements about this capture are true? (Choose two.)

  • A: It is set to run for five minutes.
  • B: It continues to capture data after the buffer is full.
  • C: It is set to run for a period of00:03:26.
  • D: It captures data only until the buffer is full.
  • E: It is set to use the default buffer type.

Correct Answer: AB

Question 6

Which statement about NAT64 is true?

  • A: It uses one-to-one mapping between IPv6 addresses and IPv4 addresses.
  • B: It requires static address mapping between IPv6 addresses and IPv4 addresses.
  • C: It can be used to translate an IPv6 network to another IPv6 network.
  • D: It can be configured for stateless and stateful translation.

Correct Answer: D




Question 7

Refer to the exhibit. 

  

Which two possible network conditions can you infer from this configuration? (Choose two.)

  • A: The authentication parameters on R1 and R2 are mismatched.
  • B: R1 is using the default NTP source configuration.
  • C: R1 and R2 have established an NTP session.
  • D: R2 is configured as the NTP master with a stratum of 7.

Correct Answer: AB

Answer A: The NTP associations are not synced, it is only listed as a candidate because it was configured. Routing is not the issue, so it must be mismatched authentication parameters. Answer B: NTP sets the source IP address for all NTP packets based on the address of the interface through which the NTP packets are sent. You can configure NTP to use a specific source IP address.




Question 8

Which option is the common primary use case for tools such as Puppet, Chef, Ansible, and Salt?

  • A: network function virtualization
  • B: configuration management
  • C: network orchestration
  • D: policy assurance

Correct Answer: B

  • A: Neutron server plugin
  • B: Neutron DHCP agent
  • C: Neutron Layer 3 agent
  • D: Identity Service
  • E: Neutron Layer 2 agent

Correct Answer: AD




Question 10

Which two characteristics of an IoT network are true? (Choose two.)

  • A: IoT networks must be designed for low-powered devices.
  • B: The transmission rate in an IoT network is consistent
  • C: IoT networks use IS-IS for routing
  • D: IoT networks are bandwidth constrained.
  • E: IoT networks are 100% reliable.
