最新的 JNCIA JN0-106 免費考試真題 (Q60-Q65):

問題 #60
Your switch01 device lost network connectivity after a configuration change. You must recover the device to a known working state using the rescue configuration that was previously saved. The device is only accessible using the console. In this scenario, which command sequence will successfully restore the rescue configuration?

答案：A

解題說明：
In Junos OS, the rescue configuration is a specifically designated file that stores a known-working configuration, intended to be used for emergency recovery when the device becomes unreachable or unstable due to recent changes. This configuration is not created automatically; an administrator must proactively save a stable state using the operational mode command request system configuration rescue save. This differs from the standard rollback archive, which automatically stores up to 50 previous configurations but can eventually rotate out the specific " last known good " state needed for recovery.
When a device loses network connectivity, console access becomes the only viable management path. To restore the rescue configuration, the administrator must enter configuration mode using the configure command. Once inside the candidate configuration buffer, the rollback rescue command is issued. This command directs the Junos OS to locate the designated rescue file and load its contents over the current candidate configuration. Upon receiving the " load complete " confirmation, the administrator must execute a commit to promote the candidate configuration to the active, running state. Sequence C correctly follows this logic. Sequence A is technically incorrect for standard rescue restoration as load override typically targets specific file paths or URLs, whereas rollback rescue is the built-in mechanism for this function. Sequences B and D are destructive or counter-productive, either deleting the rescue file or overwriting it with the current, non-functional configuration state. Reference: Operational Monitoring and Maintenance, Configuration Recovery, Rescue Configuration.


問題 #61
What is a benefit of using J-Web?

答案：C

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 #62
Which two common routing policy actions affect the flow of policy evaluation? (Choose two.)

答案：C,D

解題說明：
In Junos OS routing policy evaluation, "next policy" (A) and "next term" (C) are common actions that affect the flow of policy evaluation. "Next policy" directs the evaluation to the next policy in the sequence, whereas "next term" moves the evaluation to the next term within the current policy, allowing for granular control over routing decisions.


問題 #63
Which two statements are correct regarding Layer 2 network switches? (Choose two.)

答案：B,D

解題說明：
Layer 2 network switches are crucial components in local area networks (LANs), providing multiple functions for data packet forwarding and network segmentation. One inherent characteristic of switches is their susceptibility to traffic loops, especially in networks with redundant paths. Without proper loop prevention protocols like Spanning Tree Protocol (STP), loops can cause broadcast storms and network instability. Additionally, switches inherently flood broadcast traffic to all ports within the broadcast domain, except the port on which the broadcast was received. This is because broadcast frames are meant to be delivered to all devices within the VLAN, and the switch ensures this by flooding these frames to all ports in the VLAN, except the source port.


問題 #64
Which criteria does the Junos OS use to select an active route when two entries exist in the routing table?

答案：A

解題說明：
In Junos OS, when two entries for the same destination exist in the routing table, the route with the lowest preference number is selected as the active route. This preference number, also known as the route preference or administrative distance, is used to prioritize routes received from different routing protocols.
