최신 JNCIA JN0-105 무료샘플문제 (Q68-Q73):

질문 # 68
Exhibit
policy-options { policy-statement Load-Balance-Policy { term Load-Balance { then { load-balance per-flow; accept;
}
}
}
}
routing-options {
router-id 192.168.100.11; autonomous-system 65201; forwarding-table {
export Load-Balance-Policy;
Referring to the exhibit, which two statements are correct? (Choose two.)

A. The policy enables flow-based load balancing.
B. The policy enables equal cost load balancing in the forwarding table.
C. The policy enables per-packet load balancing.
D. The policy must be applied under the protocols hierarchy.

정답：B

설명：
Theload-balance per-flowstatement in the Junos OS policy-options configuration enables flow-based load balancing in the forwarding table. This means that the traffic is distributed across multiple paths based on flows, where a flow is typically identified by attributes such as source and destination IP addresses, and possibly layer 4 information like TCP/UDP ports. This allows for more granular and efficient utilization of available paths, avoiding overloading a single path. The policy does not enable per-packet load balancing, which would send individual packets of the same flow over different paths, potentially causing out-of-order delivery issues. The policy's placement in theforwarding-tableexport suggests it's intended to influence forwarding behavior, not just routing protocol decisions, and does not necessarily have to be applied under the protocols hierarchy.

질문 # 69
Which two statements are true about the PFE? (Choose two.)

A. The PFE uses Layer 2 and Layer 3 forwarding tables to forward traffic toward its destination.
B. The PFE implements various services such as policing, stateless firewall filtering, and class of service.
C. The PFE is responsible for performing protocol updates and system management.
D. The PFE handles all processes that control the chassis components.

정답：A,B

설명：
The Packet Forwarding Engine (PFE) in Juniper Networks devices is the heart of the data plane, handling the actual forwarding of packets based on pre-computed forwarding tables. It provides several critical services to manage and control traffic flow, including policing (to enforce bandwidth limits for certain traffic types), stateless firewall filtering (to permit or deny traffic based on predefined criteria), and Class of Service (CoS) (to prioritize traffic to ensure quality of service for critical applications). The PFE utilizes both Layer 2 (MAC addresses) and Layer 3 (IP addresses) forwarding tables to make intelligent forwarding decisions, ensuring that packets are efficiently routed toward their final destination.

질문 # 70
Click the Exhibit button.

How is traffic, sourced from 10.0.0.0/8, treated by the firewall filter shown in the exhibit?

A. logged and rejected
B. logged and accepted
C. logged and discarded
D. logged with no further action

정답：B

설명：
The firewall filter configuration in the exhibit specifies a filter with two terms. Term 1 matches traffic from the source address 10.0.0.0/8 and has two actions: 'log' and 'next term'. The 'log' action will record the match to a log file, and 'next term' indicates that the firewall should evaluate the next term after logging. There is no explicit action such as 'accept' or 'reject' in term 1, so by default, the traffic will be accepted unless subsequently rejected by another term.
Term 2 has the action 'reject', which discards packets that reach this term. Since there is no 'from' condition in term 2, it acts as a default rule for all traffic not matched by term 1.
Because the traffic sourced from 10.0.0.0/8 matches term 1 and there is no reject action in that term, it will be logged and then accepted by the firewall filter. There is no subsequent term that rejects this specific traffic, so the action from term 2 does not apply to it.

질문 # 71
You have configured some interfaces on a Junos device; however, you have not yet committed the configuration.
What happens if you issue the rollback 0 command in this scenario?

A. The interface changes you made are discarded.
B. The Junos device is rebooted.
C. The factory default configuration is loaded.
D. The messages.log file is deleted.

정답：A

설명：
Issuing the rollback 0 command in Junos OS will discard any uncommitted changes and revert to the last committed configuration. This command effectively cancels any configuration changes that have been made but not yet committed, ensuring that the device returns to its previous stable state.

질문 # 72
Which Junos feature limits the amount of exception traffic that is sent from the PFE to the RE?

A. CoS markings
B. routing policy
C. scheduler
D. policer

정답：D

설명：
In Junos OS, a policer is a feature used to limit the rate of traffic flow in the network, including exception traffic sent from the Packet Forwarding Engine (PFE) to the Routing Engine (RE). Exception traffic consists of packets that cannot be processed by the PFE alone and requireintervention by the RE, such as control packets or packets destined for the device itself. A policer can be configured to enforce bandwidth limits and drop or mark packets that exceed specified rate limits, thus protecting the RE from being overwhelmed by excessive exception traffic.
