Juniper Junos, Associate (JNCIA-Junos) JN0-106 Prüfungsfragen mit Lösungen (Q87-Q92):

87. Frage
You are trying to diagnose packet loss at interface ge-0/0/3. In this scenario, which command would help you view error statistics in real time?

Antwort: C

Begründung:
The monitor interface ge-0/0/3 command is used in Junos OS to view real-time statistics for a specific interface. This command helps in diagnosing issues like packet loss by displaying real- time updates of traffic and error statistics for the specified interface.


88. Frage
What are two requirements for root password recovery in Junos? (Choose two.)

Antwort: B,D

Begründung:
Root password recovery in Junos OS is a critical administrative procedure designed to regain access to the management plane when the root credentials are lost. This process is fundamentally tied to the physical security of the device, as it requires two specific conditions that cannot be met over a standard network connection. First, the administrator must have direct console access to the device. Because the recovery process involves interrupting the Junos boot sequence before the operating system kernel and its associated security services (such as SSH) are fully initialized, it must be performed through the serial management port.
Second, a system reboot is mandatory. The recovery mechanism is triggered by interrupting the boot loader (typically the " Loader " or " U-Boot " stage) by pressing the Space bar or a specific key sequence during power-on. This allows the administrator to enter " single-user mode " or boot into a " recovery " state. Once in this restricted environment, the device mounts its internal storage in a way that permits the modification of the root authentication parameters without requiring the existing password. This workflow intentionally bypasses the standard authentication database to restore management control while preserving the rest of the device configuration. This procedure underscores the importance of securing physical access to the chassis, as anyone with console access and the ability to cycle power can eventually gain root-level authority over the system.

89. Frage
How many rescue configuration files are supported on a Junos device?

Antwort: B

Begründung:
Junos OS supports only 1 rescue configuration file on a device. This rescue configuration is a safeguard feature that allows network administrators to revert to a known good configuration in case of a configuration error or issue, ensuring network stability.


90. Frage
You want to redeploy a Junos device by clearing the existing configuration and resetting it to factory defaults.
In this scenario, which command would help to accomplish this task?

Antwort: A

Begründung:
When a network architect needs to completely sanitize a Junos device for redeployment or decommissioning, the request system zeroize command is the most thorough tool available. Unlike simply loading the factory default configuration, which only resets the configuration database, the zeroize command performs a deep wipe of the system.
Specifically, this command removes all user-created data, including all configuration files (active and rollback), log files, license keys, and any locally stored files in the /var/tmp or /home directories. It essentially restores the device to its " pristine " out-of-box state. Once the command is initiated, the device reboots and goes through a sanitization process. This is a critical security measure to ensure that sensitive information- such as encrypted passwords, proprietary routing policies, or SNMP community strings-does not leave the organization when hardware is transferred.
In contrast, the request system storage cleanup command is a maintenance utility used to delete temporary files and old log entries to free up disk space, but it does not affect the running configuration or user accounts.
Therefore, for a total system reset that includes configuration deletion, zeroize is the mandatory operational command.
Reference: Operational Monitoring and Maintenance, System Sanitization, request system zeroize.


91. Frage
You manage a Junos device with 20 interfaces. Each interface requires the same description and MTU setting. Which configuration approach would reduce repetitive commands and ensure consistency?

Antwort: C

Begründung:
A configuration group allows you to define common settings once and apply them to multiple interfaces, ensuring consistency and reducing repetitive configuration.
