Question 61<\/b><\/h3>\n

Which Junos command displays a summary of the routing protocols running on the device?<\/b><\/p>\n

    \n
  1. show route protocol<\/span><\/li>\n
  2. show route summary<\/span><\/li>\n
  3. show protocols summary<\/span><\/li>\n
  4. show routing protocols<\/span><\/li>\n<\/ol>\n

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

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

    The show route summary command provides a summary of routing information maintained by the Junos device. It can help administrators understand the overall contents of the routing table, including the number of routes associated with different protocol sources. This command is useful when a quick overview is needed instead of examining every individual route. Administrators can use the summary together with more detailed routing commands to investigate specific routing problems. Reviewing route statistics is an important troubleshooting step when verifying whether expected routes have been learned and installed correctly.<\/span><\/p>\n

    Question 62<\/b><\/h3>\n

    Which type of route is automatically created when an interface is configured with an IP address and becomes operational?<\/b><\/p>\n

      \n
    1. Static route<\/span><\/li>\n
    2. Direct route<\/span><\/li>\n
    3. BGP route<\/span><\/li>\n
    4. OSPF route<\/span><\/li>\n<\/ol>\n

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

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

      A direct route represents a network that is directly connected to an operational interface. When an interface is configured with an IP address and is operational, Junos can install a direct route for the associated network in the routing table. This allows the device to recognize destinations belonging to that directly connected network. Direct routes are different from static and dynamically learned routes because they result from the device’s own interface configuration. Administrators can use routing-table commands to verify that expected direct routes are present.<\/span><\/p>\n

      Question 63<\/b><\/h3>\n

      Which route type is manually configured by a network administrator?<\/b><\/p>\n

        \n
      1. Direct route<\/span><\/li>\n
      2. Static route<\/span><\/li>\n
      3. OSPF route<\/span><\/li>\n
      4. BGP route<\/span><\/li>\n<\/ol>\n

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

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

        A static route is manually configured by a network administrator rather than being learned through a dynamic routing protocol. Static routes can be useful for simple networks, specific destinations, backup paths, or situations where predictable routing behavior is required. Because static routes do not automatically adapt to topology changes, administrators must update them when network requirements change. In Junos, static routes are configured under the appropriate routing-options hierarchy. Administrators can verify their installation by examining the routing table after committing the configuration.<\/span><\/p>\n

        Question 64<\/b><\/h3>\n

        Which Junos hierarchy is used to configure static routes?<\/b><\/p>\n

          \n
        1. interfaces<\/span><\/li>\n
        2. protocols<\/span><\/li>\n
        3. routing-options<\/span><\/li>\n
        4. system<\/span><\/li>\n<\/ol>\n

          Correct Answer: 3<\/b><\/p>\n

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

          Static routes are configured under the routing-options hierarchy in Junos OS. This hierarchy contains several routing-related settings, including static routes and other routing options. Administrators can specify a destination prefix and the appropriate next hop or other forwarding information. After making the configuration change, the administrator must commit it before the static route becomes active. Understanding the location of static-route configuration within the Junos hierarchy helps administrators work efficiently and reduces configuration errors when implementing manually defined routes.<\/span><\/p>\n

          Question 65<\/b><\/h3>\n

          Which command can be used to test connectivity using a specific source address?<\/b><\/p>\n

            \n
          1. ping source<\/span><\/li>\n
          2. ping <destination> source <source-address><\/span><\/li>\n
          3. test source ping<\/span><\/li>\n
          4. monitor ping source<\/span><\/li>\n<\/ol>\n

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

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

            Junos allows administrators to specify a source address when using the ping command. This is useful when a device has multiple interfaces or addresses and the administrator needs to test connectivity from a particular source. For example, specifying a source address can help determine whether routing or filtering behaves differently depending on where the traffic originates. This is especially valuable during troubleshooting on routers with multiple interfaces. Using source-specific testing provides more precise information than simply sending a ping from the default source address.<\/span><\/p>\n

            Question 66<\/b><\/h3>\n

            Which command can be used to determine the network path toward a remote destination?<\/b><\/p>\n

              \n
            1. traceroute<\/span><\/li>\n
            2. route-path<\/span><\/li>\n
            3. path-test<\/span><\/li>\n
            4. trace-route-table<\/span><\/li>\n<\/ol>\n

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

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

              The traceroute command is used to identify the path packets take toward a remote destination. It can reveal intermediate routers between the source and destination and provide response information for each hop. This makes traceroute useful when investigating routing problems, unexpected paths, or points where connectivity may be failing. Ping can establish basic reachability, but traceroute provides additional information about the path itself. Administrators often use both commands together when troubleshooting connectivity issues across multiple network segments.<\/span><\/p>\n

              Question 67<\/b><\/h3>\n

              Which Junos feature allows configuration changes to be scheduled for automatic rollback if not confirmed?<\/b><\/p>\n

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

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

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

                The commit confirmed feature allows an administrator to activate configuration changes temporarily while requiring confirmation within a specified period. If the administrator does not issue a regular commit before the confirmation timer expires, Junos automatically rolls back to the previous committed configuration. This feature is particularly useful when making remote changes that could potentially disrupt connectivity. If a configuration error causes the administrator to lose access, the automatic rollback can restore the previous working configuration. This provides an important safety mechanism for remote configuration work.<\/span><\/p>\n

                Question 68<\/b><\/h3>\n

                What is the primary benefit of using commit confirmed?<\/b><\/p>\n

                  \n
                1. It permanently disables configuration validation<\/span><\/li>\n
                2. It provides automatic recovery if changes are not confirmed<\/span><\/li>\n
                3. It deletes previous configurations<\/span><\/li>\n
                4. It disables routing protocols<\/span><\/li>\n<\/ol>\n

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

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

                  The primary benefit of commit confirmed is that it provides a safety mechanism when applying potentially disruptive configuration changes. The administrator can commit the changes with a confirmation timer. If the administrator successfully verifies that the device is operating correctly, another commit can confirm the configuration permanently. If confirmation does not occur before the timer expires, Junos automatically returns to the previous committed configuration. This is particularly valuable when administrators are working remotely because it reduces the risk of becoming permanently locked out due to an incorrect configuration.<\/span><\/p>\n

                  Question 69<\/b><\/h3>\n

                  Which Junos command can be used to display information about the system’s installed processes?<\/b><\/p>\n

                    \n
                  1. show system processes<\/span><\/li>\n
                  2. show processes system<\/span><\/li>\n
                  3. display system process<\/span><\/li>\n
                  4. monitor system process<\/span><\/li>\n<\/ol>\n

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

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

                    The show system processes command provides information about processes running on a Junos device. Administrators can use process information when investigating high resource utilization, unexpected behavior, or system performance problems. The output can help identify processes consuming CPU or other system resources. This command is primarily useful for operational monitoring and troubleshooting rather than configuration. When investigating a complex issue, administrators may combine process information with system logs, interface statistics, routing information, and other operational commands to understand the overall condition of the device.<\/span><\/p>\n

                    Question 70<\/b><\/h3>\n

                    Which command displays information about system storage and file systems?<\/b><\/p>\n

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

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

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

                      The show system storage command displays information about storage usage and file systems on a Junos device. Monitoring available storage is important because insufficient disk space can affect system operations, logging, software management, and other functions. Administrators can use this command to identify storage areas that are becoming full and determine whether cleanup or maintenance may be required. Regular storage monitoring can help prevent avoidable operational problems, especially on devices that retain significant logs, software packages, or configuration-related files.<\/span><\/p>\n

                      Question 71<\/b><\/h3>\n

                      Which Junos command displays messages from the system log file named messages?<\/b><\/p>\n

                        \n
                      1. show log messages<\/span><\/li>\n
                      2. show messages log<\/span><\/li>\n
                      3. display system messages<\/span><\/li>\n
                      4. monitor messages file<\/span><\/li>\n<\/ol>\n

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

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

                        The show log messages command displays entries from the Junos messages log file. The messages log commonly contains information about system events, interface changes, authentication activity, configuration operations, and other operational conditions. Administrators can use the log to investigate when a particular event occurred and identify related system messages. Log analysis is an important part of network troubleshooting because some problems may not be visible through interface or routing commands alone. Reviewing timestamps and related entries can help establish the sequence of events during an incident.<\/span><\/p>\n

                        Question 72<\/b><\/h3>\n

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

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

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

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

                          The show configuration interfaces command displays interface-related configuration statements from the active Junos configuration. Administrators can use it to review interface addresses, descriptions, units, VLAN settings, and other configured parameters. It is useful when comparing the intended configuration with the operational status shown by interface commands. Configuration information and operational information serve different purposes, so administrators often use both when troubleshooting. Reviewing the interface hierarchy can also help identify incorrect or missing configuration statements that may be affecting connectivity.<\/span><\/p>\n

                          Question 73<\/b><\/h3>\n

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

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

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

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

                            The show interfaces command provides operational information about interfaces on a Junos device. Depending on the options used, it can display physical and logical interface status, traffic statistics, errors, packet counters, and other operational details. Administrators can specify an individual interface to focus on a particular connection. This command is commonly used during troubleshooting because it provides much more information than a basic interface summary. Examining interface operational data can help determine whether a problem is related to physical connectivity, configuration, traffic, or errors.<\/span><\/p>\n

                            Question 74<\/b><\/h3>\n

                            Which Junos command displays the MAC address learned on Ethernet interfaces?<\/b><\/p>\n

                              \n
                            1. show ethernet mac-table<\/span><\/li>\n
                            2. show ethernet-switching table<\/span><\/li>\n
                            3. show mac addresses<\/span><\/li>\n
                            4. show interfaces mac<\/span><\/li>\n<\/ol>\n

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

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

                              The show ethernet-switching table command can be used on Junos switching platforms to display MAC addresses learned by the Ethernet switching process. The MAC table associates Layer 2 addresses with interfaces and, where applicable, VLAN information. Switches use these learned entries to forward Ethernet frames toward the appropriate interface instead of flooding every frame throughout the network. Administrators can examine the table when troubleshooting switching, VLAN, or host-connectivity problems. MAC-table information is particularly useful for determining where a device’s Layer 2 address has been learned.<\/span><\/p>\n

                              Question 75<\/b><\/h3>\n

                              What does a switch use a MAC address table for?<\/b><\/p>\n

                                \n
                              1. Selecting IP routing protocols<\/span><\/li>\n

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

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

                                A MAC address table allows a Layer 2 switch to associate destination MAC addresses with specific interfaces. When a switch receives an Ethernet frame, it examines the destination MAC address and uses the table to determine the appropriate outgoing interface when a matching entry exists. If the destination is unknown, the switch may flood the frame within the relevant broadcast domain. As devices communicate, the switch learns source MAC addresses and builds its table dynamically. This process enables efficient Ethernet frame forwarding within switched networks.<\/span><\/p>\n

                                Question 76<\/b><\/h3>\n

                                Which technology separates a Layer 2 network into multiple logical broadcast domains?<\/b><\/p>\n

                                  \n
                                1. VLAN<\/span><\/li>\n

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

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

                                  A VLAN, or Virtual Local Area Network, logically separates a switched network into different broadcast domains. Devices in different VLANs are separated at Layer 2 even when they share the same physical switching infrastructure. VLANs are commonly used to organize users, services, or departments and to control broadcast traffic. Communication between different VLANs generally requires Layer 3 routing. Junos switching platforms support VLAN configuration and associated interface settings. Understanding VLANs is fundamental to Ethernet switching and network segmentation.<\/span><\/p>\n

                                  Question 77<\/b><\/h3>\n

                                  Which IEEE standard is associated with VLAN tagging on Ethernet frames?<\/b><\/p>\n

                                    \n
                                  1. 802.1X<\/span><\/li>\n

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

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

                                    IEEE 802.1Q defines VLAN tagging for Ethernet networks. VLAN tags allow switches to identify the VLAN associated with an Ethernet frame as it travels across trunk links. This makes it possible to carry traffic belonging to multiple VLANs over the same physical connection. VLAN tagging is commonly used between switches and other network devices that need to transport multiple logical networks. Understanding 802.1Q is important when configuring VLAN trunks and troubleshooting connectivity between devices across a switched infrastructure.<\/span><\/p>\n

                                    Question 78<\/b><\/h3>\n

                                    Which interface type is commonly used to carry traffic for multiple VLANs?<\/b><\/p>\n

                                      \n
                                    1. Access interface<\/span><\/li>\n

                                    4. Management-only interface<\/span><\/li>\n<\/ol>\n

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

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

                                      A trunk interface is commonly used to carry traffic belonging to multiple VLANs across a single physical connection. VLAN identification is maintained using tagging, typically based on IEEE 802.1Q. Trunks are frequently used between switches, routers, and other devices that need to transport several VLANs. An access interface generally carries traffic for a single VLAN without requiring VLAN tags for ordinary endpoint communication. Correct trunk configuration is important because mismatched VLAN settings can prevent devices in different parts of a network from communicating properly.<\/span><\/p>\n

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

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

                                        A network switch primarily operates at the data-link layer and forwards Ethernet frames using MAC addresses. It learns source MAC addresses and associates them with interfaces in its forwarding table. When a frame arrives, the switch examines the destination MAC address and determines where to send the frame. Modern switches can also support Layer 3 functions, but their fundamental switching role is based on Layer 2 forwarding. Routers primarily make forwarding decisions using Layer 3 IP information and routing tables.<\/span><\/p>\n

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

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

                                          A loopback interface is a logical interface that is not directly tied to a physical network port. Because it can remain operational as long as the device itself is functioning, loopback addresses are often useful for device identification, routing protocols, management, and other services. A loopback interface can provide a stable address even when individual physical interfaces change state. This makes loopbacks particularly useful in routing environments where a consistent address is needed for protocol sessions or management purposes.<\/span><\/p>\n
