Refer to the exhibit. What two statements describe the NTP status of the router? (Choose two.)

Introduction

Network Time Protocol (NTP) is a cornerstone of modern network management, ensuring that devices across a network maintain synchronized time. For IT professionals pursuing certifications like Cisco’s CCNA or CCNP, understanding NTP and interpreting its status on routers is critical. The question, “Refer to the exhibit. What two statements describe the NTP status of the router? (Choose two.)” is a common multiple-choice query in certification exams, testing your ability to analyze NTP configurations and outputs. This Exam Prep Study Guide, brought to you by DumpsQueen, provides an in-depth exploration of NTP, its status indicators, and how to interpret router outputs to answer such questions confidently. Whether you’re preparing for a Cisco exam or seeking to enhance your networking expertise, this guide will equip you with the knowledge to master NTP-related concepts.

What is NTP and Why It Matters

NTP is a protocol designed to synchronize the clocks of computers and network devices over a network. Accurate timekeeping is essential for various network functions, including logging events, scheduling tasks, and securing communications. For instance, time.g., timestamps in logs must align across devices to ensure accurate troubleshooting. Without synchronized time, diagnosing network issues or correlating security events becomes challenging.

On a router, NTP allows the device to synchronize its clock with a reliable time source, such as an NTP server. This synchronization ensures that the router’s time-based functions, like certificate validation for VPNs or time-based access control lists, operate correctly. For certification candidates, understanding how to configure and verify NTP on a router is a key skill, and questions like “Refer to the exhibit. What two statements describe the NTP status of the router?” test your ability to interpret command outputs, such as those from show ntp status or show ntp associations.

Decoding the “Refer to the Exhibit” Question

In certification exams, questions often include an “exhibit,” which is typically a screenshot or text output from a router’s command-line interface (CLI). For NTP-related questions, the exhibit might display the output of commands like show ntp status, show ntp associations, or show ntp associations detail. These commands provide insights into the router’s NTP configuration, synchronization status, and relationships with NTP servers.

The question “What two statements describe the NTP status of the router? (Choose two.)” requires you to analyze the exhibit and select two correct statements from a list of options. To answer correctly, you need to understand key NTP concepts, such as stratum levels, synchronization status, and association types. Let’s break down the components of NTP status and how they appear in router outputs.

Understanding NTP Status Outputs

The show ntp status Command

The show ntp status command provides a snapshot of the router’s NTP synchronization state. Key elements in this output include:

• Clock Synchronization Status: Indicates whether the router’s clock is synchronized with an NTP server. The output might state “Clock is synchronized” or “Clock is unsynchronized.” A synchronized clock means the router is successfully aligned with a time source.

• Stratum Level: Represents the distance from a reference clock. A stratum 1 device is directly connected to a high-precision time source, like a GPS clock, while a stratum 2 device synchronizes with a stratum 1 device, and so on. Lower stratum numbers indicate higher accuracy.

• Reference ID: Identifies the IP address or name of the NTP server the router is synchronized with. If unsynchronized, this field might show “.INIT.” or another placeholder.

• Poll Interval: The frequency (in seconds) at which the router queries the NTP server.

• Last Update: The time elapsed since the last successful NTP update.

For example, an output like “Clock is synchronized, stratum 3, reference is 192.168.1.10” indicates that the router is synchronized with an NTP server at IP 192.168.1.10 and operates at stratum 3.

The show ntp associations Command

The show ntp associations command lists the NTP servers or peers the router is configured to communicate with. Each entry includes:

• Server IP Address: The address of the NTP server.

• Stratum: The stratum level of the server.

• When: Time since the last NTP packet was received.

• Poll: The polling interval for this association.

• Reach: An octal value indicating successful communication attempts (e.g., 377 means all recent attempts succeeded).

• Delay, Offset, Jitter: Metrics describing the round-trip delay, time offset from the server, and variability in delay, respectively.

A prefix like “*” before an entry indicates that this is the server the router is synchronized with, while “+” denotes a candidate server, and “-” indicates an out-of-spec server.

Interpreting the Exhibit

When answering “What two statements describe the NTP status of the router?”, you’ll need to analyze the exhibit for clues. For instance, if the show ntp status output shows “Clock is unsynchronized, stratum 16,” one correct statement might be “The router’s clock is not synchronized with an NTP server.” If the show ntp associations output lists a server with a “*” prefix and stratum 2, another correct statement could be “The router is synchronized with a stratum 2 NTP server.”

Common distractors in multiple-choice options might include incorrect stratum levels, misinterpretations of synchronization status, or confusion between server and peer roles. By carefully reading the exhibit, you can avoid these pitfalls.

Key NTP Concepts for Exam Success

Stratum Levels and Their Significance

Stratum levels are a hierarchy of time sources. A stratum 1 server, often connected to a GPS or atomic clock, provides the highest accuracy. A router synchronized with a stratum 1 server becomes stratum 2, and so on. In exam questions, you might need to identify the router’s stratum level from the show ntp status output or determine the stratum of the server it’s synchronized with.

Synchronization Status

A router’s clock is either synchronized or unsynchronized. Synchronization requires successful communication with an NTP server, typically indicated by a “*” in the show ntp associations output and a stratum level lower than 16 in show ntp status. Unsynchronized routers (stratum 16) cannot provide reliable time to other devices.

Association Types

NTP associations can be servers (the router queries them for time) or peers (devices exchange time bidirectionally). Exam questions may test your ability to distinguish these roles from the show ntp associations output, where servers are typically marked with “*” or “+” and peers with “=”.

Polling and Reachability

The poll interval determines how often the router queries an NTP server, while the reach field shows the success rate of recent queries. A reach value of 0 indicates no successful communication, which could explain why a router is unsynchronized.

Strategies for Answering NTP Questions

To excel at questions like “Refer to the exhibit. What two statements describe the NTP status of the router?”, follow these steps:

1. Analyze the Exhibit Carefully: Read the entire output, noting the synchronization status, stratum level, and reference ID in show ntp status, or the prefix and reach values in show ntp associations.

2. Match Options to Output: Compare each multiple-choice option to the exhibit. Eliminate options that contradict the output, such as claiming synchronization when the clock is unsynchronized.

3. Understand Context: Consider the router’s role (e.g., client or server) and the network environment depicted in the exhibit.

4. Practice with Realistic Outputs: Familiarize yourself with show ntp status and show ntp associations outputs through practice labs or simulators.
