Path Control and IP SLA Practice Questions

  1. Question 1: Routing protocol convergence time would be an example of which path control consideration?
    Answer: Availability
  2. Question 2: A BGP routing policy has been created using route maps. The command route-map TEST permit 10 is part of the configuration. What does the argument 10 indicate?
    Answer: It identifies the position of the route map in relation to other instances.
  3. Question 3: Refer to the exhibit. What would be the RIP routing metric for the subnets of the 172.16.0.0/16 network on the R2 router after the configuration in the exhibit was applied to the R1 router?
    Answer: 4
  4. Question 4: Refer to the exhibit. The routing policy for router R1 states that traffic from the 192.168.1.0 LAN network is to be routed to ISP-1 and traffic from the 172.16.1.0 LAN network is to be routed to ISP-2. However, the network administrator notices that a host at IP address 172.16.1.10 is being routed out Serial0/0/0. What is the cause of the problem?
    Answer: The route map ISP-2 should be applied to FastEthernet0/1.
  5. Question 5: What are three accurate descriptors of the functionality of the Cisco IOS IP SLA feature? (Choose three.)
    Answer:
    • The sending of simulated data
    • A requirement that NTP be configured on source and responder
    • Verification that the TCP or UDP ports on a target are active and responsive

  6. Question 6: Refer to the exhibit. Based on the information that is presented, which statement is true?
    Answer: Access list 2 specifies that packets with a source address of 172.16.1.0 will be policy routed.
  7. Question 7: What is the purpose of using an offset list when implementing path control in EIGRP?
    Answer: To increase incoming and outgoing metrics to routes learned by EIGRP
  8. Question 8: Quality of Service (QoS) and Cisco Wide Area Application Services (WAAS) are two examples of which path control consideration?
    Answer: Support for network and application services
  9. Question 9: Refer to the exhibit. On the basis of the information presented, which two IP SLA related statements are true? (Choose two.)
    Answer:
    • IP SLA 99 is sending echo requests every 10 seconds.
    • IP SLA 99 will run forever unless explicitly disabled.

  10. Question 10: Which two descriptions are accurate about the path control functionality of offset lists? (Choose two.)
    Answer:
    • Used to increase metrics
    • Can be applied only to routes that are learned via distance vector protocols

  11. Question 11: Which two IP SLA path control statements are true? (Choose two.)
    Answer:
    • An IP SLA operation is a measurement that includes protocol, frequency, traps, and thresholds.
    • The IOS IP SLA feature allows performance measurements between a Cisco device and another Cisco device or a host.

  12. Question 12: Refer to the exhibit. RIPv2 is configured on routers in the network. Which commands would an administrator use to configure an offset list?
    Answer:
    router rip
offset-list 1 in 5 serial 0/0/0
access-list 1 permit 192.168.1.0 0.0.0.255

  13. Question 13: Which two commands can be used to verify that an offset list has altered the path taken by traffic? (Choose two.)
    Answer:
    • traceroute
    • show ip route

  14. Question 14: Refer to the exhibit. On the basis of the information presented, which statement is true?
    Answer: A default static route was configured with the track keyword.
  15. Question 15: When policy-based routing (PBR) is being implemented, which set command will override explicit entries in the routing table?
    Answer: set ip next-hop
  16. Question 16: Refer to the exhibit. Which configuration will ensure that traffic that originates from network 172.16.1.0 will be forwarded out Serial 0/0/0?
    Answer:
    R1(config)# access-list 1 permit 172.16.1.0 0.0.0.255
R1(config)# route-map ISP-1 permit 10
R1(config-route-map)# match ip address 1
R1(config-route-map)# set interface s0/0/0
R1(config)# interface fa0/1

  17. Question 17: Refer to the exhibit. Assuming all FastEthernet interfaces have been configured with the ip policy route-map LOAD_BALANCE command and are up, how will router R1 treat packets that are received from network 10.2.0.0 and destined for the Internet?
    Answer: Will be routed normally based on the routing table
  18. Question 18: Which path control consideration creates an effective use of bandwidth by having traffic use different paths for opposite directions?
    Answer: Asymmetric routing
  19. Question 19: Which path control consideration helps provide an acceptable level of service when a failure occurs?
    Answer: Resiliency
  20. Question 20: Which IP SLA statement is true?
    Answer: To increase security of IP SLAs control messages, Message Digest 5 (MD5) authentication can be used.
