Selected Answer: D
D. NTP (Network Time Protocol) IP SLA (Internet Protocol Service Level Agreement) is a feature in Cisco IOS that allows administrators to measure and monitor network performance. One of the types of performance measurements that can be performed using IP SLA is UDP jitter, which is a measure of the variability in the delay of UDP packets. To measure UDP jitter using IP SLA, the NTP (Network Time Protocol) feature must be enabled on the device. NTP is used to synchronize the device's clock with a reference time source, which is necessary to accurately measure the delay of UDP packets. Without NTP, the device's clock may drift over time, leading to inaccurate jitter measurements. Therefore, the correct answer is D. NTP.

Time synchronization, such as that provided by the Network Time Protocol (NTP), is required between the source and the target device to provide accurate one-way delay (latency) measurements. This part in his link proves that NTP is the right answer here. Thanks for the link,

The problem with such links, specially from Cisco, is that you have to read a whole book to get an answer, and that is if you are lucky. Thanks anyway.

Is this required for the 200-301 exam? I don't remember seeing this topic covered on my netacad online course. Thanks

The correct answer is B. EEM (Embedded Event Manager). IP SLA (Internet Protocol Service Level Agreement) is a feature in Cisco IOS that allows network administrators to measure various network performance metrics. To measure UDP jitter using IP SLA, the EEM feature is required. EEM provides the necessary scripting capabilities to configure and monitor IP SLA operations, including the measurement of UDP jitter. LLDP (Link Layer Discovery Protocol), CDP (Cisco Discovery Protocol), and NTP (Network Time Protocol) are not directly related to measuring UDP jitter using IP SLA. LLDP and CDP are network discovery protocols, while NTP is used for time synchronization in network devices.

The keyword is "UDP". Both LLDP and CDP are Layer 2 neighbor discovery protocols. EEM = Embedded Event Manager. So the answer is D.

Jitter has somthing to do with time, NTP synchronizes time, thus NTP the most likely

Interesting blog post on IP SLA that is worth skimming over.. https://learningnetwork.cisco.com/s/blogs/a0D3i000002SKN0EAO/ip-sla-fundamentals Does not mention NTP, though this is the correct answer as LTTAM and oooMooo have pointed out.
