最新的 JNCIA JN0-106 免費考試真題 (Q23-Q28):

問題 #23
Referring to the exhibit, which route(s) will be selected by Junos for packet forwarding?

答案：C

解題說明：
Junos OS selects routes based on the route preference (also known as administrative distance).
Static routes typically have a lower route preference than OSPF routes, meaning they are more preferred. Since the static route to 192.168.36.1/32 is shown with a preference of 5, it will be selected over the OSPF route for packet forwarding, assuming no other factors such as route filters or policies affect the routing decision.


問題 #24
You need to recover the root password on a Junos router without losing the current configuration settings. Which three statements describe what you should perform in this scenario? (Choose three.)

答案：A,B,C

解題說明：
To recover the root password on a Junos router without losing the configuration, you should (A) enter and commit the new root password once you have gained access to the system, (D) hit the space bar to interrupt the boot process and enter recovery mode when prompted during the boot process, and (E) use a console connection to reboot the device and access the bootloader prompt. These steps allow you to reset the root password while preserving the existing configuration.


問題 #25
Which two statements are examples of exception traffic? (Choose two.)

答案：B,D

解題說明：
In the Junos architecture, exception traffic consists of packets that cannot be handled by the Packet Forwarding Engine (PFE) alone and must be punted to the Routing Engine (RE) for specialized processing.
The first category of exception traffic is management/protocol traffic destined for the local device . For instance, SSH traffic to the local Junos OS device is an exception because the RE must terminate the TCP connection, authenticate the user, and present the CLI. Other examples include SNMP polls, BGP updates, and OSPF Hellos.
The second category involves packets with specific IP options or headers that require RE intervention. An IP packet with the Router Alert option (typically used by protocols like RSVP or IGMP) explicitly tells every router in the path, " Hey, stop and look at my payload. " Because the PFE is optimized for high-speed forwarding and not for interpreting complex options, it sends these packets to the RE. Conversely, traffic destined for a remote internet server (transit traffic) or packets with CoS bits (which are processed in hardware by the PFE) do not hit the RE. Exception traffic is strictly policed by the " internal link " rate limiters to ensure the RE is never overwhelmed by a flood of packets requiring software-based processing.

問題 #26
What is the main function of the forwarding table on a Junos device?

答案：D

解題說明：
The forwarding table contains the active routes derived from the routing table and is used by the Packet Forwarding Engine to forward packets.


問題 #27
What is the purpose of an ARP packet?

答案：D

解題說明：
The Address Resolution Protocol (ARP) is a fundamental Layer 2 utility used within the IPv4 suite to resolve a known network-layer (Layer 3) address to its corresponding physical media access control (MAC) or hardware address (Layer 2). In a typical Ethernet environment, when a Junos device needs to forward a packet to a next-hop on a local subnet, the Packet Forwarding Engine (PFE) requires the destination MAC address to properly encapsulate the frame.
The process begins with an ARP Request, which is broadcast to all hosts on the segment asking, " Who owns this IP address? " The host assigned that specific IP responds with an ARP Reply containing its MAC address.
The Junos device then stores this mapping in its ARP cache (viewable via the show arp command) to avoid repeated broadcasts for subsequent packets. This resolution is essential because while IP addresses facilitate end-to-end logical routing, the actual delivery of data across a physical wire or switch fabric relies entirely on hardware addresses. Without successful ARP resolution, the device cannot complete the Layer 2 header, and the traffic will be dropped as " encapsulation failed. " Reference: Networking Fundamentals, Ethernet and Address Resolution Protocol.
