Question 141<\/b><\/h3>\n

Which Junos command displays NTP configuration and synchronization information?<\/b><\/p>\n

    \n
  1. show system ntp<\/span><\/li>\n
  2. show ntp status<\/span><\/li>\n
  3. show system time-sync<\/span><\/li>\n
  4. show protocols ntp<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    The show system ntp command can be used to display NTP-related information on a Junos device. NTP allows the system clock to synchronize with configured time sources. Accurate time is important for log correlation, troubleshooting, monitoring, and security investigations. When checking NTP operation, administrators can review the configured servers and synchronization state. If a device is not synchronized, possible causes include unreachable NTP servers, incorrect configuration, or network connectivity problems. Proper time synchronization helps ensure that timestamps generated by the device are reliable.<\/span><\/p>\n

    Question 142<\/b><\/h3>\n

    Which Junos command displays the current system time?<\/b><\/p>\n

      \n
    1. show clock<\/span><\/li>\n
    2. show system clock<\/span><\/li>\n
    3. show time<\/span><\/li>\n
    4. show system uptime<\/span><\/li>\n<\/ol>\n

      Correct Answer: 1<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      The show clock command displays the current date and time maintained by the Junos device. Verifying the system clock is useful when troubleshooting logs, authentication problems, scheduled operations, or NTP synchronization. Device timestamps are especially important when administrators need to correlate events across several network devices. If the clock is incorrect, log entries may appear out of sequence or become difficult to compare with events recorded by other systems. NTP can be used to keep the system clock synchronized with reliable time sources.<\/span><\/p>\n

      Question 143<\/b><\/h3>\n

      Which command displays detailed information about a Junos interface?<\/b><\/p>\n

        \n
      1. show interfaces detail<\/span><\/li>\n
      2. show interface information<\/span><\/li>\n
      3. show interfaces status<\/span><\/li>\n
      4. show interface detail<\/span><\/li>\n<\/ol>\n

        Correct Answer: 1<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        The show interfaces detail command provides detailed operational information about interfaces. Depending on the interface and platform, the output can include administrative and operational status, hardware information, traffic statistics, error counters, and addressing information. Detailed interface output is useful when troubleshooting connectivity or performance issues. Administrators can compare this information with simpler commands such as show interfaces terse. The terse command provides a compact summary, while the detail form provides considerably more information for diagnosing interface behavior.<\/span><\/p>\n

        Question 144<\/b><\/h3>\n

        Which Junos command provides extensive interface statistics and error information?<\/b><\/p>\n

          \n
        1. show interfaces extensive<\/span><\/li>\n
        2. show interfaces statistics<\/span><\/li>\n
        3. show interface errors<\/span><\/li>\n
        4. show ports extensive<\/span><\/li>\n<\/ol>\n

          Correct Answer: 1<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          The show interfaces extensive command provides extensive operational information about interfaces. The output can include packet and byte counters, error statistics, interface state, physical properties, and other details depending on the interface type. This command is useful when troubleshooting issues such as packet loss, interface errors, or abnormal traffic behavior. Administrators can examine input and output statistics to determine whether a problem is occurring on a particular interface. It is often used together with logs and other operational commands during troubleshooting.<\/span><\/p>\n

          Question 145<\/b><\/h3>\n

          Which command displays a compact summary of interface status and addressing?<\/b><\/p>\n

            \n
          1. show interfaces terse<\/span><\/li>\n
          2. show interfaces brief<\/span><\/li>\n
          3. show interface summary<\/span><\/li>\n
          4. show ports terse<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            The show interfaces terse command provides a concise summary of interface information. It commonly shows interface names, administrative status, link status, and configured protocol addresses. Because the output is compact, it is useful for quickly checking many interfaces at once. Administrators frequently use this command as an initial troubleshooting step before examining a specific interface in greater detail. If a problem is identified, commands such as show interfaces detail or show interfaces extensive can then provide additional operational information.<\/span><\/p>\n

            Question 146<\/b><\/h3>\n

            What does an interface’s administrative status indicate?<\/b><\/p>\n

              \n
            1. Whether the interface is intentionally enabled or disabled<\/span><\/li>\n
            2. Whether the interface has an IP address<\/span><\/li>\n
            3. Whether OSPF is enabled<\/span><\/li>\n
            4. Whether packets are being routed<\/span><\/li>\n<\/ol>\n

              Correct Answer: 1<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              Administrative status indicates whether an interface has been configured to be enabled or disabled. An administrator can intentionally disable an interface when it should not be used. This is different from operational status, which indicates whether the interface is actually functioning at the link level. For example, an interface may be administratively enabled but operationally down because of a cable, transceiver, or remote-device problem. Understanding the difference between administrative and operational status helps administrators troubleshoot interface availability accurately.<\/span><\/p>\n

              Question 147<\/b><\/h3>\n

              Which configuration statement administratively disables a Junos interface?<\/b><\/p>\n

                \n
              1. disable<\/span><\/li>\n
              2. shutdown<\/span><\/li>\n
              3. deactivate interface<\/span><\/li>\n
              4. disable-interface<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                The disable statement is used under an interface configuration hierarchy to administratively disable that interface. A disabled interface will not operate normally until the configuration is changed and committed. Administrators may disable unused interfaces for security or operational reasons. This can also be useful during maintenance or troubleshooting. When reviewing an interface that is unexpectedly down, administrators should check whether a disable statement is present in its configuration. The configuration must be committed for the administrative change to become active.<\/span><\/p>\n

                Question 148<\/b><\/h3>\n

                Which Junos command can display the configuration of a specific interface?<\/b><\/p>\n

                  \n
                1. show interfaces configuration<\/span><\/li>\n
                2. show configuration interfaces ge-0\/0\/0<\/span><\/li>\n
                3. show interface config ge-0\/0\/0<\/span><\/li>\n
                4. show interfaces ge-0\/0\/0 configuration<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 2<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  The show configuration interfaces ge-0\/0\/0 command displays the configured statements for the specified interface. It allows administrators to review settings such as descriptions, addresses, VLAN membership, units, and other interface-specific configuration. Reviewing the actual configuration is an important troubleshooting step because the operational state alone does not show every configured parameter. The interface name in the command should be replaced with the appropriate interface for the device. Administrators can also use hierarchical configuration commands to inspect related sections.<\/span><\/p>\n

                  Question 149<\/b><\/h3>\n

                  Which Junos command displays the active configuration in set-style format?<\/b><\/p>\n

                    \n
                  1. show configuration | display set<\/span><\/li>\n
                  2. show | display configuration<\/span><\/li>\n
                  3. show configuration set<\/span><\/li>\n
                  4. display set configuration<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    The show configuration | display set command displays configuration statements using set-style syntax. This format represents hierarchical configuration as individual set commands, which can be useful when documenting configurations or preparing commands for another device. For example, instead of showing nested hierarchy, the output presents complete paths for individual configuration statements. Administrators often use this format when comparing configurations or copying specific settings. It is particularly useful for understanding exactly which command statements create a particular configuration.<\/span><\/p>\n

                    Question 150<\/b><\/h3>\n

                    Which Junos command checks whether the candidate configuration contains syntax or configuration errors before committing?<\/b><\/p>\n

                      \n
                    1. commit check<\/span><\/li>\n
                    2. check configuration<\/span><\/li>\n
                    3. verify commit<\/span><\/li>\n
                    4. validate system<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 1<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      The commit check command validates the candidate configuration without activating the changes. It allows Junos to identify configuration problems before an actual commit is performed. This is useful when administrators have made several changes and want to verify that the configuration is acceptable. A successful commit check does not activate the configuration; the administrator still needs to issue commit to make the changes active. Using commit check can reduce the chance of discovering configuration problems only after attempting to deploy changes.<\/span><\/p>\n

                      Question 151<\/b><\/h3>\n

                      What happens when the Junos commit command is successfully executed?<\/b><\/p>\n

                        \n
                      1. Candidate configuration becomes active<\/span><\/li>\n
                      2. Device immediately reboots<\/span><\/li>\n
                      3. All previous configurations are deleted<\/span><\/li>\n
                      4. Routing protocols are permanently disabled<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        A successful commit activates the candidate configuration and makes it the active configuration on the Junos device. Junos separates configuration editing from activation, allowing administrators to make and review changes before applying them. This transactional approach helps reduce accidental configuration errors. A commit does not normally reboot the device or delete previous configuration history. Junos also provides rollback functionality, allowing administrators to return to previously committed configurations when necessary. Administrators should review important changes carefully before committing them.<\/span><\/p>\n

                        Question 152<\/b><\/h3>\n

                        Which Junos command activates the candidate configuration and automatically rolls it back if it is not confirmed within the specified time?<\/b><\/p>\n

                          \n
                        1. commit confirmed<\/span><\/li>\n
                        2. commit rollback<\/span><\/li>\n
                        3. commit automatic<\/span><\/li>\n
                        4. commit timer<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          The commit confirmed command activates a configuration temporarily and starts a confirmation timer. If the administrator does not issue another commit to confirm the configuration before the timer expires, Junos automatically rolls back to the previous committed configuration. This feature is especially useful when making remote changes that could accidentally disconnect management access. If the configuration causes a connectivity problem, the automatic rollback can restore the previous working state. It provides an additional safety mechanism for remote configuration changes.<\/span><\/p>\n

                          Question 153<\/b><\/h3>\n

                          Which command confirms a previously issued commit confirmed operation?<\/b><\/p>\n

                            \n
                          1. commit<\/span><\/li>\n
                          2. commit confirm<\/span><\/li>\n
                          3. confirm configuration<\/span><\/li>\n
                          4. commit activate<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            After using commit confirmed, issuing the normal commit command confirms the configuration and prevents the automatic rollback from occurring. This mechanism allows an administrator to test connectivity and verify that the configuration works correctly before permanently confirming it. If the administrator does not confirm the configuration within the specified period, Junos reverts to the previous committed configuration. This feature is particularly valuable for remote management because it provides a recovery mechanism if a configuration change disrupts access.<\/span><\/p>\n

                            Question 154<\/b><\/h3>\n

                            Which Junos command displays previously committed configuration versions?<\/b><\/p>\n

                              \n
                            1. show system rollback<\/span><\/li>\n
                            2. show rollback<\/span><\/li>\n
                            3. show configuration history<\/span><\/li>\n
                            4. show system configuration versions<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              The show system rollback command displays information about configuration rollback files maintained by Junos. Junos keeps previous committed configurations so that administrators can review or restore earlier versions when necessary. Rollback files are useful when a recent configuration change introduces an unexpected problem. Administrators can inspect earlier configurations and use rollback commands to return the candidate configuration to a previous state. Understanding rollback functionality is important for safe configuration management and recovery from configuration mistakes.<\/span><\/p>\n

                              Question 155<\/b><\/h3>\n

                              Which command loads a previous rollback configuration into the candidate configuration?<\/b><\/p>\n

                                \n
                              1. rollback<\/span><\/li>\n
                              2. load rollback<\/span><\/li>\n
                              3. restore configuration<\/span><\/li>\n
                              4. recover rollback<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                The rollback command loads a previous committed configuration into the candidate configuration. It does not immediately activate the rollback. After loading the desired rollback version, the administrator can review the resulting candidate configuration and then commit it if appropriate. This separation between loading and activation is part of the Junos configuration model. Rollback is useful when a recent configuration change causes operational problems and the administrator needs to restore an earlier known configuration.<\/span><\/p>\n

                                Question 156<\/b><\/h3>\n

                                Which command displays differences between the candidate and active configurations?<\/b><\/p>\n

                                  \n
                                1. show | compare<\/span><\/li>\n
                                2. show configuration differences<\/span><\/li>\n
                                3. compare configuration<\/span><\/li>\n
                                4. diff configuration active<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 1<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  The show | compare command displays differences between the candidate configuration and the currently active configuration. It is useful after making configuration changes because administrators can review exactly what will be changed before committing. Added, modified, or deleted statements can be identified through the comparison output. This provides an important validation step in Junos configuration workflows. Reviewing differences before committing can help catch accidental changes and reduce configuration errors, especially when multiple configuration areas have been modified.<\/span><\/p>\n

                                  Question 157<\/b><\/h3>\n

                                  Which Junos command displays system uptime and load information?<\/b><\/p>\n

                                    \n
                                  1. show system uptime<\/span><\/li>\n
                                  2. show uptime<\/span><\/li>\n
                                  3. show system status<\/span><\/li>\n
                                  4. show chassis uptime<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    The show system uptime command displays information about how long the Junos device has been running and can also provide load-related information. System uptime can help administrators determine whether a device recently restarted and can provide context during troubleshooting. Unexpected reboots may indicate power problems, software issues, or other system events. The command is commonly used alongside log inspection and system-health commands to investigate unexpected restarts. Uptime information alone does not explain why a reboot occurred, so additional evidence should be reviewed when necessary.<\/span><\/p>\n

                                    Question 158<\/b><\/h3>\n

                                      Correct Answer: 1<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      The show chassis hardware command displays hardware information about the Junos device. Depending on the platform, the output can include chassis details, Routing Engines, line cards, modules, power supplies, and other installed components. This command is useful for verifying the physical hardware inventory and identifying component models. Administrators can use the information when troubleshooting hardware-related problems or confirming that expected components are installed. The exact output varies according to the Juniper platform and hardware architecture.<\/span><\/p>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        The show system alarms command displays active system alarms reported by the Junos device. Alarms can indicate conditions that require administrator attention, including hardware or environmental issues depending on the platform. Reviewing alarms is an important part of routine device health monitoring. When an alarm appears, administrators should investigate its cause rather than simply clearing the notification. Additional commands, logs, and platform-specific information may be required to determine the exact condition that generated the alarm.<\/span><\/p>\n

                                        4. display log messages<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 1<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          The show log messages command displays entries from the messages log file on a Junos device. System logs contain information about operational events, interface changes, authentication activity, routing events, system processes, and other conditions depending on the configured logging policies. Administrators frequently review logs when troubleshooting unexpected behavior because they provide a chronological record of events. Log information can be combined with operational commands such as show interfaces, show route, and show system processes to develop a clearer understanding of a problem.<\/span><\/p>\n
