最新的 JNCIA JN0-106 免費考試真題 (Q41-Q46):

問題 #41
Which protocol is primarily used in Junos devices to discover neighboring devices and exchange basic information such as system name and port identification?

答案：D

解題說明：
LLDP (Link Layer Discovery Protocol) is used for device discovery at Layer 2. It allows network devices to advertise identity and capabilities to neighbors. Unlike routing protocols like OSPF or BGP, LLDP does not participate in routing decisions but aids in network visibility.


問題 #42
How are the Routing Engine and the Packet Forwarding Engine components connected?

答案：D

解題說明：
The fundamental architecture of Junos OS is built upon the clean separation of the Control Plane (Routing Engine or RE) and the Forwarding Plane (Packet Forwarding Engine or PFE). While these two components perform vastly different tasks, they must maintain a high-speed, reliable communication channel to synchronize the state of the device. This connection is achieved through an internal Ethernet link .
This internal link serves several critical functions. First, it allows the Routing Engine to " push " the distilled forwarding table (FIB) to the PFE, ensuring that the hardware knows exactly how to handle incoming transit traffic at wire speed. Second, it acts as a conduit for exception traffic . If the PFE receives a packet that it cannot handle alone-such as an OSPF hello, a BGP update, or an ICMP " Time Exceeded " message-it sends that packet over the internal Ethernet link to the RE for processing. This link is carefully policed by built-in rate limiters to ensure that a flood of transit-related exception traffic cannot overwhelm the Routing Engine ' s CPU, a mechanism known as control plane protection. By using a standard Ethernet-based internal fabric, Junos ensures a scalable and modular design where the RE can focus on complex protocol calculations while the PFE focuses on the heavy lifting of packet switching.

問題 #43
A network administrator must set up the initial configuration of the out-of-band management interface on a new Juniper router to ensure management traffic is isolated from the default routing table (inet.0). In this scenario, which configuration step is required to accomplish this task in Junos OS?

答案：A

解題說明：
The out-of-band management interface (fxp0 or em0) must be assigned an IP address and placed into the dedicated management routing instance using the system management-instance configuration, which isolates management traffic from the default inet.0 routing table.


問題 #44
What is a benefit of using J-Web?

答案：A

解題說明：
If you've committed a configuration and then need to revert to the previous configuration, the rollback command is used. Since the incorrect IP address has not been committed, as indicated by the commit check command being successful, issuing rollback 1 will undo the changes made in the current session, which includes the accidental entry of the IP address.


問題 #45
You have logged on to a Junos device and are at the operational mode prompt. Which two commands are used at this prompt? (Choose two.)

答案：A,B

解題說明：
At the operational mode prompt on a Junos device, you can use various commands to view the device's status and request system operations. The show interface ge-0/0/0 command is used to display information about a specific interface, while the request system shutdown command is used to properly shut down the device. The request system shutdown is a valid operational mode command to gracefully shut down the device.
