>> Certification JN0-352 Test Answers <<
Everything needs a right way. The good method can bring the result with half the effort, the same different exam also needs the good test method. Our JN0-352 study questions in every year are summarized based on the test purpose, every answer is a template, there are subjective and objective exams of two parts, we have in the corresponding modules for different topic of deliberate practice. To this end, our JN0-352 Training Materials in the qualification exam summarize some problem- solving skills, and induce some generic templates. The user can scout for answer and scout for score based on the answer templates we provide, so the universal template can save a lot of precious time for the user.
NEW QUESTION # 127
What is the purpose of the native VLAN feature on the Juniper Networks EX Series Switches?
Answer: C
Explanation:
A native VLAN is a trunk-port concept, not an access-port concept. On an 802.1Q trunk, every frame is normally expected to carry a VLAN tag identifying its membership; the native VLAN is the single exception that Junos permits an administrator to define using the native-vlan-id statement under the trunk interface's family ethernet-switching hierarchy. Any untagged frame arriving on that trunk port is automatically classified into the configured native VLAN, and conversely, outbound frames belonging to the native VLAN are transmitted untagged rather than with an 802.1Q header. This behavior exists chiefly for interoperability with legacy or third-party devices that either cannot generate 802.1Q tags or intentionally send management or default traffic untagged across an otherwise tagged trunk. Access ports, by definition, only ever carry a single VLAN's traffic and never receive tagged frames in normal operation, so the native VLAN mechanism has no relevance there -- which eliminates the access-port-oriented answer choices.
The native VLAN also does not restrict a trunk to a single VLAN; the trunk continues to carry all configured tagged VLANs simultaneously, with the native VLAN simply being the designated untagged exception. Misconfiguring or mismatching native VLAN IDs between two trunk peers is a classic Layer 2 troubleshooting scenario on the exam.
NEW QUESTION # 128
Which two characteristics describe the default behavior of aggregate routes? (Choose two.)
Answer: A,D
Explanation:
The entire purpose of route aggregation is summarization -- replacing a set of more-specific contributing routes with a single, broader prefix advertised outward -- and this summarization inherently hides internal routing instability from external peers: if one of the underlying contributing /24 blocks within a summarized /16 flaps up and down due to a local link issue, external peers who only see the stable, unchanging /16 aggregate are completely insulated from that churn, since the aggregate itself remains active and advertised as long as at least one contributing route is present, regardless of how much internal fluctuation occurs among the individual contributors. This stability- hiding characteristic is one of the primary operational benefits that motivates using aggregate routes in the first place, confirming that statement as correct. Regarding next-hop behavior, official Juniper documentation is explicit and unambiguous:
when an aggregate route is installed in the routing table, Junos assigns it a reject next hop by default, meaning traffic matching only the aggregate (and no more-specific contributor) is dropped and an ICMP unreachable message is returned to the source; a discard next hop is available only as an optional, explicitly configured alternative when silent dropping without ICMP notification is preferred, but it is not the default. Aggregate routes categorically do not advertise their individual contributing routes; suppressing those specific, more- granular prefixes from onward advertisement in favor of the single summary is the aggregate's defining function, directly contradicting the first statement.
NEW QUESTION # 129
What are three valid OSPF adjacency states? (Choose three.)
Answer: B,C,D
Explanation:
OSPF neighbor state progression, as defined in RFC 2328 and displayed by Junos through show ospf neighbor, moves through a well-defined set of named states: Down, Attempt, Init, 2-Way, ExStart, Exchange, Loading, and Full. Down is the initial state, indicating no Hello packets have been recently received from a potential neighbor on that interface; it is a genuine, valid OSPF state and is correctly included here. Init indicates that a Hello packet has been received from the neighbor, but that neighbor has not yet listed the local router's own router ID within its Hello packet, so bidirectional communication has not yet been confirmed; this too is a standard, valid state. Loading occurs after the Exchange state, during which Database Description packets have been fully exchanged and the router is now actively requesting the specific, more-detailed LSAs it identified as missing or outdated from its neighbor via Link State Request packets; it is likewise a standard, valid OSPF neighbor state. 'Established' is not an OSPF state at all -- that terminology belongs to BGP's finite state machine, where Established represents the fully operational session state; the OSPF equivalent concept is instead called Full. 'Reject' is not a recognized OSPF neighbor state under any circumstance and does not appear anywhere in the RFC 2328 state machine, making it an invalid distractor as well.
NEW QUESTION # 130
You are troubleshooting a BGP routing issue between your network and a customer router and are reviewing the BGP routing policies. Which two statements are correct in this scenario?
(Choose two.)
Answer: A,B
Explanation:
In BGP, routing policies are used to control the flow of routing information between BGP peers.
Option C suggests that import policies are applied after the RIB-In table. This is correct because import policies in BGP are applied to routes that are received from a BGP peer, before they are installed in the local BGP Routing Information Base (RIB-In). The RIB-In is a database that stores all the routes that are received from all peers.
Option D suggests that export policies are applied after the RIB-Local table. This is correct because export policies in BGP are applied to routes that are being advertised to a BGP peer, after they have been selected from the local BGP Routing Information Base (RIB-Local). The RIB-Local is a database that stores all the routes that the local router is using.
