質問 # 75
Which Junos OS command is used to display general information about installed interfaces, including their administrative and link status?
正解：C
解説：
The show interfaces terse command provides a concise summary of interfaces, including their administrative status (up/down), link status, and any configured IP addresses.
質問 # 76
Which command displays real-time usage statistics for all interfaces?
正解：B
解説：
The monitor interface traffic command displays real-time usage statistics for all interfaces on a Junos device.
質問 # 77
Which two operational mode commands would you use to verify CPU and memory utilization on a Junos device? (Choose two.)
正解：B、D
解説：
In the Junos OS architecture, maintaining visibility into the health of the Routing Engine (RE) is paramount for ensuring control plane stability. The command show chassis routing-engine is the primary tool for a high-level hardware status overview. It provides critical telemetry regarding the RE's current CPU utilization (broken down by user, background, and kernel tasks), memory usage statistics, and uptime. This command is essential for identifying if the device's "brain" is under significant stress due to heavy protocol processing or management tasks.
For a more granular, process-specific analysis, the show system processes extensive command is utilized. Similar to the 'top' utility in Unix-based systems, it lists all active software daemons (such as rpd for routing, dcd for interfaces, and mgd for management) and ranks them by their real-time CPU and memory consumption. This allows an architect to pinpoint exactly which process might be causing a performance bottleneck. While show chassis environment focuses on physical hardware health like temperatures and fan speeds, and resource-monitor provides summary data, the combination of show chassis routing-engine and show system processes extensive offers the most comprehensive diagnostic view of the device's internal computational resources.
質問 # 78
Click the Exhibit button.
Referring to the exhibit, which two actions will occur when a packet matches the firewall filter? (Choose two.)
正解：B、C
解説：
In Junos OS, firewall filters are constructed using terms that specify match criteria (the from statement) and actions to be taken (the then statement). When a packet enters an interface where this filter is applied, the Packet Forwarding Engine (PFE) evaluates it against the defined terms. In this exhibit, the term limit-icmp targets packets sourced from the 172.25.11.0/24 network that specifically use the ICMP protocol.
When a packet meets both criteria, the actions defined in the then block are triggered:
* count count-icmp; : This is a non-terminating action . It instructs the system to increment a specific software counter named count-icmp. This allows administrators to monitor exactly how many packets are hitting this specific term using the show firewall command.
* discard; : This is a terminating action . It immediately stops any further evaluation of the packet and drops it. A key characteristic of the discard action in Junos is that it is a " silent " drop; the router simply deletes the packet from its buffer without notifying the sender.
Option D is incorrect because returning an ICMP destination unreachable message is the specific behavior of the reject action, not the discard action. Option C is incorrect because discard explicitly prevents the packet from being forwarded. Understanding the distinction between silent discards and active rejections is essential for architects when designing security policies that balance stealth with network transparency.

質問 # 79
You want to automatically back up your Junos device configuration to an external server every time you commit a configuration change. In this scenario, which command would accomplish this task?
正解：B
解説：
Junos OS provides robust automation features for configuration management, specifically through the system archival utility. When an administrator needs to ensure that every successful configuration change is mirrored to an off-box repository for disaster recovery or auditing, the transfer-on-commit statement is the appropriate tool. This command instructs the Junos device to initiate an automated upload process immediately following the validation and activation of a commit command.
To fully implement this, the administrator must also define the archive-sites, which specify the destination URIs (using protocols such as FTP, SCP, or HTTP) and the necessary credentials for the external server. While transfer-interval can be used to back up configurations on a chronological schedule (e.g., every 60 minutes), transfer-on-commit is superior for tracking specific change events as they happen. This ensures that the external backup is always synchronized with the current active configuration on the device. Once configured, the device handles the background transfer, allowing the administrator to maintain a historical record of configuration states without manual intervention, which is essential for large-scale operational environments.
