質問 # 79
Click the Exhibit button.
Referring to the exhibit, which two actions will occur when a packet matches the firewall filter? (Choose two.)
正解：A、D
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.

Which two types of traffic are processed by the Routing Engine? (Choose two.)
正解：A、B
解説：
The Routing Engine (RE) is the control-plane component of a Junos OS device. Its primary responsibilities include routing protocol processing, system management, maintaining routing tables, running Junos OS processes, and providing administrative access. Consequently, management traffic and control traffic are processed by the Routing Engine. Juniper specifically describes the Routing Engine as controlling routing updates and system management , while routing protocol packets from the network are directed to the Routing Engine.
Management traffic includes traffic associated with services such as SSH, Telnet, SNMP, and other traffic whose destination is the device itself. Control traffic includes routing protocol communications such as OSPF, BGP, and other protocol packets required to establish and maintain the device ' s control-plane state. Juniper categorizes these as local packets , which are handled by the Routing Engine.
By contrast, transit traffic enters one physical interface and is forwarded toward another destination. This forwarding operation is normally handled by the Packet Forwarding Engine (PFE) rather than the Routing Engine. The separation of forwarding and control functions is fundamental to Junos OS architecture.

質問 # 81
Referring to the exhibit, which routing configuration is required for these two users to access the remote server?
正解：D
解説：
In a typical network configuration, users and servers require a default gateway to communicate with devices on different networks or subnets. The default gateway is usually the router's interface on the same network, which routes the traffic to other networks. This is essential for the two users to access the remote server if the server is on a different subnet, which is indicated by the different network addresses.
質問 # 82
Which statement accurately describes the Junos candidate configuration?
正解：D
解説：
In the Junos OS architecture, the configuration environment is strictly bifurcated to ensure system stability and integrity. The candidate configuration is a specific database that serves as a staging area, storing all proposed changes made by an administrator during a configuration session before they are finalized. Unlike other network operating systems where changes might take effect immediately upon entry, Junos utilizes this "sandbox" approach where modifications reside only in the candidate database until a commit command is explicitly executed.
Once the commit process is initiated, the Junos OS kernel validates the candidate configuration for syntax errors and logical consistency. If the validation check is successful, the candidate configuration is promoted and becomes the active configuration--the operational state currently running on the device hardware. This separation allows multiple administrators to work on complex changes without impacting live transit traffic or device stability prematurely. If a mistake is identified during the editing process, the candidate configuration can be easily discarded or compared against the active state to identify discrepancies. This workflow is a cornerstone of Junos OS, facilitating a "check-before-apply" methodology that is essential for carrier-grade reliability and minimizing the risk of accidental outages during critical maintenance windows.
質問 # 83
On a Junos device, what is the purpose of configuring a loopback interface (lo0)?
正解：C
解説：
The loopback interface is a logical interface that stays up as long as the Routing Engine is operational, making it ideal for stable management access and routing protocol references such as router IDs.
