IP SLA Questions
Question 1
Question 2
Explanation
IP SLA PBR (Policy-Based Routing) Object Tracking allows you to make sure that the next hop is reachable before that route is used. If the next hop is not reachable, another route is used as defined in the PBR configuration. If no other route is present in the route map, the routing table is used.
An example of configuring PBR based on tracking object is shown below:
| //Configure and schedule IP SLA operations ip sla 1 icmp-echo 10.3.3.2 ip sla schedule 1 life forever start-time now ! // Configure Object Tracking to track the operations track 1 ip sla 1 reachability ! //Configure ACL ip access-list standard ACL permit ip 10.2.2.0/24 10.1.1.1/32 ! //Configure PBR policing on the router route-map PBR match ip address ACL set ip next-hop verify-availability 10.3.3.2 track 1 set ip next-hop verify-availability 10.3.3.2 track 2 -> Track 2 is not shown here but it is used if track 1 fails ! //Apply PBR policy on the incoming interface of the router. interface ethernet 0/0 ip address 10.2.2.1 255.255.255.0 ip policy route-map PBR |
Question 3
Explanation
The keyword “tcp-connect” enables the responder for TCP connect operations. TCP is a connection-oriented transport layer protocol -> C is correct.
Question 4
Explanation
The “num-packets” specifies the number of packets to be sent for a jitter operation.
The “frequency” is the rate (in seconds) at which this IP SLA operation repeats. The “tos” defines a type of service (ToS) byte in the IP header of this IP SLA operation.
Question 5
Explanation
When enabled, the IP SLAs Responder allows the target device to take two time stamps both when the packet arrives on the interface at interrupt level and again just as it is leaving, eliminating the processing time. At times of high network activity, an ICMP ping test often shows a long and inaccurate response time, while an IP SLAs test shows an accurate response time due to the time stamping on the responder.
An additional benefit of the two time stamps at the target device is the ability to track one-way delay, jitter, and directional packet loss. Because much network behavior is asynchronous, it is critical to have these statistics. However, to capture one-way delay measurements the configuration of both the source device and target device with Network Time Protocol (NTP) is required. Both the source and target need to be synchronized to the same clock source. One-way jitter measurements do not require clock synchronization.
Question 6
Question 7
Question 8
Explanation
Depending on the specific Cisco IOS IP SLAs operation, statistics of delay, packet loss, jitter, packet sequence, connectivity, path, server response time, and download time are monitored within the Cisco device and stored in both CLI and SNMP MIBs.
Reference: http://www.cisco.com/c/en/us/td/docs/ios/12_4/ip_sla/configuration/guide/hsla_c/hsoverv.html
Question 9
Explanation
IP SLAs supports proactive threshold monitoring and notifications for performance parameters such as average jitter, unidirectional latency, bidirectional round-trip time (RTT), and connectivity for most IP SLAs operations. The proactive monitoring capability also provides options for configuring reaction thresholds for important VoIP related parameters including unidirectional jitter, unidirectional packet loss, and unidirectional VoIP voice quality scoring.
IP SLAs reactions are configured to trigger when a monitored value exceeds or falls below a specified level or when a monitored event, such as a timeout or connection loss, occurs. If IP SLAs measures too high or too low of any configured reaction, IP SLAs can generate a notification (in the form of SNMP trap) to a network management application or trigger another IP SLA operation to gather more data.
Cisco IOS IP SLAs can send SNMP traps that are triggered by events such as the following:
+ Connection loss
+ Timeout
+ Round-trip time threshold
+ Average jitter threshold
+ One-way packet loss
+ One-way jitter
+ One-way mean opinion score (MOS)
+ One-way latency
Question 10
Explanation
Round-trip time (RTT), also called round-trip delay, is the time required for a packet to travel from a specific source to a specific destination and back again.
An ICMP Path Echo operation measures end-to-end (full path) and hop-by-hop response time (round-trip delay) between a Cisco router and devices using IP. ICMP Path Echo is useful for determining network availability and for troubleshooting network connectivity issues.
Note: ICMP Echo only measures round-trip delay for the full path.
Question 11
Explanation
The default route command (at the last line) must include the “track” keyword for the tracking feature to work.
| ip route 0.0.0.0.0 0.0.0.0 172.20.20.2 track 10 |

IP SLA Tracking with Configuration Example
Configuration
<ip sla 1
icmp-echo 4.2.2.2
timeout 500
frequency 3
ip sla schedule 1 start-time now life forever
track 1 rtr 1 reachability
now for the routing, we need to change the default route and associate it with the tracker
no ip route 0.0.0.0 0.0.0.0 1.1.1.1
and then put it back with the tracking
ip route 0.0.0.0 0.0.0.0 1.1.1.1 track 1

Hey, passed route exam today. I can confirm a lot has changed. No more than 20-30% of Qs came from valid dumps like tut, 480Q, 454Q, 149Q. On the bright side, all 3 SIM questions were valid. Please study harder
Q6 @dgtut: Please correct the answer, should be A, not B. As per Cisco documentation:
” For state, if the return code is OK, the track state is up; if the return code is not OK, the track state is down. For reachability, if the return code is OK or OverThreshold, reachability is up; if not OK, reachability is down.”
E.g Reference:
https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/sweot.html
agree with renewer
when tracking state only then only an OK means up anything else means down
When tracking reachability then OK or overThreashold means up anything else means down
https://www.cisco.com/c/en/us/td/docs/ios/ipsla/command/reference/sla_book/sla_05.html#wp1093733
Q6 is wrong. According to Cisco’s website, the answer should be “A”.
State = ok is up. all other return codes are down
Reachability = ok or over threshold are up. all other return codes are down
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipapp/command/iap-cr-book/iap-t1.html#GUID-63B1F5E7-1963-4F87-B04A-1EA16A049B4A
NOTE: I found that some of the composite quizzes have the correct answer.
Confirming the 539q dumps are valid.
@brendan where did u get the dump?
Two aspects of an IP SLA operation can be tracked: state and reachability. Which statement about state tracking is true?
A. When tracking state, an OK return code means that the track’s state is up; any other return code means that the track’s state is down.
B. When tracking state, an OK or over threshold return code means that the track’s state is up; any other return code means that the track’s state is down.
C. When tracking state, an OK return code means that the track’s state is down; any other return code means that the track’s state is up.
D. When tracking state, an OK or over threshold return code means that the track’s state is down; any other return code means that the track’s state is up.
Answer: B
Digitut please confirm this answer as in the Composite Quizzes the answer is different.
Please confirm as I am planning to give the exam
Hello all,
any help with Q.169
Which two reasons for IP SLA tracking failure are likely true? (Choose Two)
A.The source-interface is configured incorrectly.
B.The destination must be 172.30.30.2 for icmp-echo.
C.A route back to the RI LAN network is missing in R2.
D.The default route has wrong next hop IP address.
E.The threshold value is wrong
Correct Answer: AC
Why A is correct answer and not E?
Hi @Hangar,
E. is not correct bc the threshold value ranges from miliseconds. That means the command Threshold 500 is correct.

Correct Answer: AC
why C? i dont get it i use to work for isp, why would isp want to set up route to customers lan, and of course firewalls would not allow connection originated from outside – on untrusted interface, also when i deployed ip sla as a local admin i did not have to call isp… what the hell, can anybody explain that?

Q6 : Answer is A
The table 1 on this link give the answer : https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipapp/command/iap-cr-book/iap-t1.html#GUID-63B1F5E7-1963-4F87-B04A-1EA16A049B4A
Tracking || Return code || Track State ||
————————————————————–
State || OK || Up ||
|| All other || Down ||
————————————————————–
Reachability || Ok or over threshold || Up ||
|| All other || Down ||
————————————————————–
Q6 answer A. According to CISCO
“Object tracking of IP SLAs operations allows clients to track the output from IP SLAs objects and use this information to trigger an action. Every IP SLAs operation maintains an SNMP operation return-code value, such as OK or OverThreshold , that can be interpreted by the tracking process.
You can track two aspects of IP SLAs operation: state and reachability.
For state, if the return code is OK, the track state is up; if the return code is not OK, the track state is down.
For reachability, if the return code is OK or OverThreshold, reachability is up; if not OK, reachability is down.”
@M2,
“Two aspects of an IP SLA operation can be tracked: state and reachability. Which statement about state tracking is true?
A. When tracking state, an OK return code means that the track’s state is up; any other return code means that the track’s state is down.
B. When tracking state, an OK or over threshold return code means that the track’s state is up; any other return code means that the track’s state is down.
C. When tracking state, an OK return code means that the track’s state is down; any other return code means that the track’s state is up.
D. When tracking state, an OK or over threshold return code means that the track’s state is down; any other return code means that the track’s state is up.
Answer: B”
-Its a bit too late, but anyways, I think it should be “A”. I’m using this thread as reference: https://learningnetwork.cisco.com/thread/36909
If you configure a threshold on the ip sla operation:
Reachability –> Track up if the return code is OK or over threshold
–> Track down otherwise
State –> Track up if the return code is OK
–> Track down otherwise
This is from the Cisco configuration book, no other answers will be accepted by any other person who knows nothing about what they are talking about…
Answer A
please change the answer of question 6 to A , as it is right and not B.
