Demo Questions

Question 1

Which three IP SLA performance metrics can you use to monitor enterprise-class networks? (Choose three.)

  • A: packet loss
  • B: delay
  • C: bandwidth
  • D: connectivity
  • E: reliability
  • F: traps

Correct Answer: ABD

Cisco IOS IP SLAs collects a unique subset of the following performance metrics:
Delay (both round-trip and one-way) 
Jitter (directional) 
Packet loss (directional) 
Packet sequencing (packet ordering) 
Path(per hop) 
Connectivity (directional) 
Server or website download time 
Voice quality scores




Question 2

A network administrator notices that the BGP state and logs are generated for missing BGP hello keepalives. What is the potential problem?

  • A: hello timer mismatch
  • B: MTU mismatch
  • C: incorrect neighbor options
  • D: BGP path MTU enabled

Correct Answer: B

Introduction 
This document describes how to determine if internal or external Border Gateway Protocol (BGP) neighbor flaps are caused by maximum transmission unit (MTU) issues. 
Problem 
BGP neighbors form; however, at the time of prefix exchange, the BGP state drops and the logsgenerate missing BGP hello keepalives or the other peer terminates the session. 




Question 3

A network engineer wants to notify a manager in the event that the IP SLA connection loss threshold is reached. 
Which two features are needed to implement this functionality? (Choose two.)

  • A: Cisco IOS EEM
  • B: SNMP traps
  • C: threshold action
  • D: MOS
  • E: logging local

Correct Answer: BC

Question 4

Which Easy Virtual Networking configuration component significantly decreases network configuration?

  • A: MBGP
  • B: VNET tags
  • C: Easy Trunk
  • D: VirtualNetwork Trunk
  • E: dot1e

Correct Answer: D

EVN reduces network virtualization configuration significantly across the entire network infrastructure with the Virtual Network Trunk. The traditional VRF-Lite solution requires creating one subinterface perVRF on all switches and routers involved in the data path, creating a lot of burden in configuration management. EVN removes the need of per VRF subinterface by using “vnet trunk” command.

Question 5

A network engineer wants to display the statistics of an active tunnel on a DMVPN network. Which command should the administrator execute to accomplish this task?

  • A: router#show crypto isakmp peers
  • B: router#show crypto isakmp sa
  • C: router#show crypto ipsec transform-set
  • D: router#show crypto engine connections active
  • E: router#show crypto ipsec sa

Correct Answer: E

Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output. 
show crypto isakmp sa—Displays the state for the ISAKMP security association (SA). 
show crypto engine connections active —Displays the total encrypts/decrypts per SA. 
show crypto ipsec sa—Displays the statistics on the active tunnels. 
show ip route—Displays the routing table. 
show ip eigrp neighbor—Displays the EIGRP neighbors. 
show ip nhrp—Displays the IP Next Hop Resolution Protocol (NHRP) cache, optionally limited to dynamic or static cache entries for a specific interface. 
show crypto socket—Displays the cryptosocket table between NHRP and IPSec.

Question 6

Which IP SLA operation can be used to measure round-trip delay for the full path and hop-by hop round-trip delay on the network?

  • A: HTTP
  • B: ICMP echo
  • C: TCP connect
  • D: ICMP path echo

Correct Answer: D

The ICMP Path Echo operation computes hop-by-hop response time between a Cisco router and any IP device on the network.

Question 7

In which form does PAP Authentication send the user name and password across the link?

  • A: clear text
  • B: hashed
  • C: encrypted
  • D: password protected

Correct Answer: A




Question 8

What is the administrative distance for EBGP?

  • A: 200
  • B: 20
  • C: 30
  • D: 70

Correct Answer: B




Question 9

Considering the IPv6 address independence requirement, which process do you avoid when you use NPTv6 for translation?

  • A: IPv6 duplication and conservation
  • B: IPsec AH header modification
  • C: checksum verification
  • D: rewriting of higher layer information

Correct Answer: D

The IPv6-to-IPv6 Network Prefix Translation (NPTv6) serves as a useful mechanism for implementing address independence in an IPv6 environment. A major benefit associated with NPTv6 is the fact that it avoids the requirement for an NPTv6 Translator to rewrite the transport layer headers which reduces the load on network devices. NPTv6 also does not interfere with encryption of the full IP payload.

Question 10

What is the optimal location from which to execute a debug command that produces an excessive amount of information?

  • A: vty lines
  • B: a console port
  • C: SNMP commands
  • D: an AUXport

Correct Answer: A

Excessive debugs to the console port of a router can cause it to hang. This is because the router automatically prioritizes console output ahead of other router functions. Hence if the router is processing a large debug outputto the console port, it may hang. Hence, if the debug output is excessive use the vty (telnet) ports or the log buffers to obtain your debugs. More information is provided below.
