Frequently Asked Questions
Who should take the Juniper JN0-363 exam?
It is intended for networking professionals pursuing the Juniper Service Provider Routing & Switching Certification and working with service provider routing and switching technologies.
Is the JN0-363 exam difficult?
It can be challenging because it covers several core service provider topics such as BGP, OSPF, IS-IS, MPLS, IPv6, and high availability. Solid preparation is important.
Can I pass with only braindumps?
Braindumps alone are not the best strategy. You should use them with proper study and review so you understand the concepts behind each answer.
Do I need hands-on experience for this exam?
Hands-on experience is highly useful because the exam focuses on practical knowledge of routing, switching, and service provider behavior.
Are QA4Exam.com dumps enough, or do I need other resources?
QA4Exam.com dumps and the online practice test are strong preparation tools, but combining them with concept review gives you better retention and confidence.
How do the QA4Exam.com PDF and practice test help with first attempt success?
They help you study verified questions and answers, practice under exam-like timing, and identify weak areas before test day.
What format do the QA4Exam.com JN0-363 materials come in?
QA4Exam.com provides an Exam PDF with questions and answers plus an Online Practice Test that simulates the exam experience.

Which two statements are correct about segment routing? (Choose two.)
Segment routing is a source routing paradigm that allows a source router to define the path that a packet will take through the network by assigning an ordered list of segments---identifiers that specify a forwarding path for the packet through the network. Segment Routing can be implemented over an MPLS architecture or with IPv6 (SRv6).
A . Segment routing does not require a full mesh of adjacencies or state per transit path in the network, which is often the case with conventional MPLS signaling protocols like RSVP-TE. It leverages the existing IGP topology for forwarding without the need to maintain a state for each LSP (Label Switched Path), hence requiring very little resources to maintain.
B . In segment routing, labels (or segments) are distributed via IGP routing protocols like OSPF or IS-IS with extensions to carry segment routing information. These protocols are enhanced with Segment Routing extensions to distribute labels. For example, OSPFv2 is extended with Segment Routing extensions defined in RFC 8665.
C . This statement is not entirely correct. While it is true that segment routing does not require the maintenance of a state for each path (LSP), the concept of 'segment routing adjacencies' is a mischaracterization. Segment routing leverages the existing adjacencies formed by the underlying IGP.
D . Label assignments in segment routing are not advertised through LDP (Label Distribution Protocol) updates. Segment routing does away with LDP and instead uses IGP extensions to distribute labels.

You are asked to configure filter-based forwarding on a Junos device.
Which two statements are correct in this scenario? (Choose two.)
Filter-based forwarding in Junos requires the creation of a routing policy to specify the match conditions and actions and the application of a match filter to classify traffic to use the policy. Reference::

Exhibit
You are asked to configure OSPF between routers R1 and R2 using IPv6 addresses.
Which two tasks will accomplish your objective? (Choose two.)
To configure OSPFv3 (the version of OSPF that supports IPv6), you would use the set protocols ospf3 command with the appropriate area and interface. OSPFv3 requires a 32-bit router ID just like OSPFv2, which is typically an IPv4 address. OSPF does not use a 128-bit router ID, so answer D is incorrect.

Which new field is added to an IPv6 header as compared to IPv4?
The flow label is a new field added to IPv6 headers that was not present in IPv4 headers. It is used to identify packets that require special handling by routers, particularly for quality-of-service (QoS) purposes. Reference::

Exhibit
Referring to the exhibit, which statement is true about VRRP?
The exhibit shows the show vrrp summary output from two routers, with both routers listing the state of their VRRP group as master. VRRP allows for multiple routers to share a virtual IP address and a virtual MAC address, but usually, only one router is the master at any given time while others are in backup state. However, in some configurations, VRRP can operate in an active/active mode where multiple routers handle traffic simultaneously for load sharing. Since both routers show the state as master and there is no evidence of misconfiguration in the virtual IP addresses or priority, it indicates that VRRP is likely functioning in an active/active setup.
