Juniper Junos, Associate (JNCIA-Junos) 認定 JN0-106 試験問題 (Q32-Q37):

質問 # 32
By default, how does the PFE manage unicast traffic destined for an existing forwarding table entry?

正解:C

解説:
In a Juniper Networks device, the Packet Forwarding Engine (PFE) processes unicast traffic by forwarding it according to the existing entries in the forwarding table. When the PFE encounters unicast traffic destined for an address that has a corresponding entry in the forwarding table, it directs the traffic through a specific outgoing interface or port toward its destination. This process is based on the most efficient path determined by the routing protocols in use, ensuring that the packet reaches its intended destination through a singular path, unless specific configurations such as load balancing are in place.


質問 # 33
Exhibit:

Referring to the exhibit, with firewall filter Packet-Filter attached to an interface, if traffic is sent from
192.168.1.1 to 8.8.8.8 for a UDP DNS query, what will happen to the traffic?

正解:D

解説:
Junos OS firewall filters operate on a first-match basis, evaluating terms sequentially from top to bottom. In this scenario, a UDP DNS packet (destination port 53) is sent from 192.168.1.1 to 8.8.8.8. Evaluation begins with term 1 , which matches the correct source and destination IP addresses but specifies protocol tcp .
Because the actual traffic uses UDP, term 1 is not a match. Evaluation then moves to term 2 . While term 2 correctly identifies protocol udp and port domain (port 53), it requires the source-address to reside within the 192.168.2.0/24 subnet. Since the source is 192.168.1.1 , term 2 also fails to match.
When a packet fails to match any explicitly defined terms in a Junos firewall filter, it is subject to the implicit deny action. This default " last term " is a hardcoded safety mechanism that automatically discards all traffic that has not been explicitly permitted. Consequently, because neither term provides a match for the specific combination of source IP, protocol, and destination port, the DNS query is silently dropped by the Packet Forwarding Engine. This behavior ensures that Junos devices maintain a " deny-by-default " security posture, requiring administrators to define precise permit statements for all required transit or management traffic.

質問 # 34
What is the purpose of an ARP packet?

正解:B

解説:
The Address Resolution Protocol (ARP) is a fundamental Layer 2 utility used within the IPv4 suite to resolve a known network-layer (Layer 3) address to its corresponding physical media access control (MAC) or hardware address (Layer 2). In a typical Ethernet environment, when a Junos device needs to forward a packet to a next-hop on a local subnet, the Packet Forwarding Engine (PFE) requires the destination MAC address to properly encapsulate the frame.
The process begins with an ARP Request, which is broadcast to all hosts on the segment asking, " Who owns this IP address? " The host assigned that specific IP responds with an ARP Reply containing its MAC address.
The Junos device then stores this mapping in its ARP cache (viewable via the show arp command) to avoid repeated broadcasts for subsequent packets. This resolution is essential because while IP addresses facilitate end-to-end logical routing, the actual delivery of data across a physical wire or switch fabric relies entirely on hardware addresses. Without successful ARP resolution, the device cannot complete the Layer 2 header, and the traffic will be dropped as " encapsulation failed. " Reference: Networking Fundamentals, Ethernet and Address Resolution Protocol.


質問 # 35
What are two types of transit traffic that traverse the forwarding plane of a Layer 3 router?
(Choose two.)

正解:A、C

解説:
Transit traffic that traverses the forwarding plane of a Layer 3 router includes both unicast and multicast traffic types. Unicast traffic is directed from a single source to a single destination, while multicast traffic is sent from one source to multiple destinations that are part of a multicast group.
These types of traffic are efficiently routed through the network by leveraging the router's forwarding plane capabilities. Exception traffic, which requires special handling by the control plane, and broadcast traffic, which is typically limited to a single broadcast domain and not usually forwarded by Layer 3 routers, are not considered standard types of transit traffic for the forwarding plane of a router.


質問 # 36
What is the purpose of the "commit check" command in Junos OS when working within configuration mode before applying any changes to the system?

正解:B

解説:
The "commit check" command validates the configuration syntax and logic before applying it. It ensures that errors are caught early without impacting the running configuration. This is especially useful in production environments to prevent service disruptions due to incorrect configurations.
