質問 # 50
Which statement accurately describes the Junos OS CLI?
正解：C
解説：
The statement describing commit confirmed 5 is correct. In Junos OS, configuration changes are first made to a candidate configuration . They do not become the active operational configuration merely because they have been entered in configuration mode. A commit operation is required to validate and activate those changes.
The commit confirmed mechanism provides an important administrative safety feature. When the administrator enters:
commit confirmed 5
Junos OS activates the candidate configuration but requires confirmation within 5 minutes . If the configuration is not confirmed before the timer expires, Junos OS automatically rolls back to the previously committed configuration. Juniper explicitly documents that the optional number following commit confirmed specifies the confirmation period in minutes.
Option A is incorrect because operational mode is primarily used for monitoring, troubleshooting, maintenance, and operational commands rather than making persistent configuration changes. Option B is incorrect because configuration-mode edits remain candidate changes until committed. Option D is also incorrect: rollback 0 does not restore factory defaults . It loads the most recently committed configuration and effectively removes pending uncommitted modifications.

質問 # 51
You are creating a new user account on your Junos device. The user must be able to validate the routing table and interface statistics but should not be able to make any configuration changes. In this scenario, which permission flag would satisfy this requirement?
正解：A
解説：
User access control in Junos OS is managed through the application of permission flags within login classes. When an architect needs to define a role that allows for robust monitoring and troubleshooting without granting authority to alter the device's operational state, the view permission flag is the appropriate selection. This flag grants the user the ability to execute the majority of show commands in operational mode, which includes viewing the routing table, inspecting interface statistics, and checking hardware status.
The view permission is specifically designed for "read-only" access. It ensures that the user can observe all necessary telemetry data to validate network health--satisfying the requirement to check routing and interface stats--while strictly prohibiting access to configuration mode or any set commands. This contrasts with the configure flag, which allows modification of the candidate configuration, or the network flag, which provides specific permissions related to network-level operational tasks. By assigning a user to a class restricted with the view flag, an administrator maintains a secure environment where support personnel can diagnose issues without the risk of accidental or unauthorized configuration changes. This principle of least privilege is a cornerstone of Junos security management.
質問 # 52
Which two statements are correct about the employee@R1> prompt? (Choose two.)
正解：B、C
解説：
In Junos OS, the prompt employee@R1> indicates the current context of the user interface. The
'R1' part of the prompt signifies the hostname of the device, which in this case is 'R1'. The absence of a '#' symbol at the end of the prompt suggests that the user is in operational mode, as opposed to configuration mode which is indicated by a prompt ending in '#'. Operational mode allows users to view the status of the device and execute operational commands, but does not allow for configuration changes.
質問 # 53
Which two subnet ranges include IP address 192.168.3.29 ? (Choose two.)
正解：C、D
解説：
To determine which prefixes contain 192.168.3.29 , calculate the address range represented by each subnet mask.
A /22 prefix uses subnet mask 255.255.252.0 , producing blocks of four in the third octet. Therefore,
192.168.0.0/22 covers 192.168.0.0 through 192.168.3.255 . The address 192.168.3.29 falls within this range, making A correct .
A /28 uses mask 255.255.255.240 , creating blocks of 16 addresses. 192.168.3.0/28 covers 192.168.3.0 through 192.168.3.15 . Since 192.168.3.29 is outside this interval, B is incorrect .
A /23 uses mask 255.255.254.0 , creating blocks of two in the third octet. 192.168.2.0/23 covers 192.168.2.0 through 192.168.3.255 , so 192.168.3.29 is included , making C correct .
Finally, a /21 uses eight-value blocks in the third octet. The prefix represented by 192.168.252.0/21 belongs to the 192.168.248.0-192.168.255.255 range and therefore cannot contain 192.168.3.29.

質問 # 54
Which two statements are correct about logical units? (Choose two.)
正解：B、D
解説：
A single physical interface can be divided into multiple logical units to support different configurations. Logical units can also have multiple IP addresses assigned under the same unit.
