Juniper JN0-104 Exam Practice Questions (P. 2)

GPT-4o - Answer

When you initialize a Junos device with the factory-default configuration, setting up a root password is crucial. This requirement is enforced to enhance security by preventing unauthorized access. Without configuring a root password, attempts to commit changes to the device will be blocked, ensuring that only authenticated users can modify the system settings. The necessity of this security step cannot be bypassed and should be one of the first tasks performed during initial setup.

GPT-4o - Answer

The Routing Engine (RE) in Juniper Networks routers is vital for both network path computation and management traffic processing. Specifically, it calculates optimal routes using data from different routing protocols and static routes, ensuring efficient packet delivery across the network. Additionally, the RE manages the device through processing management traffic such as SNMP and Syslog, crucial for maintaining network health and performance. Thus, the RE not only assists in optimal routing decisions but also plays a pivotal role in network management and monitoring.

GPT-4o - Answer

The core of the Junos OS is built uniquely, combining Linux and FreeBSD to harness their strengths for network operations. Linux operates at the base metal level, optimizing performance and hardware interaction, while FreeBSD runs in a virtual environment, managing routing and control functions efficiently. This symbiotic use of two robust platforms underscores Junos OS's reliability and flexibility in handling complex network tasks.
