Actual Juniper JN0-363 Exam Questions

Question 1

Exhibit

You are asked to configure the OSPF environment to prevent the DRother routers from participating in DR/BDR election.

Referring to the exhibit, which command will accomplish this task?

Aset protocols ospf area 0.0.0.0 interface ge-0/0/l priority 255

Bset protocols ospf area 0.0.0.0 interface ge-0/0/1 priority

Cset protocols ospf area 0.0.0.0 interface ge-0/0/1 interface-type nbma

Dset protocols ospf area 0.0.0.0 interface ge---0/0/1 interface-type p2p

Correct answer: B

To prevent a router from participating in the OSPF designated router (DR) and backup designated router (BDR) election process, you set the OSPF priority to 0 on the interfaces of that router. This tells OSPF that the router on those interfaces is not to be considered for election as either DR or BDR, effectively making them DRother routers. The exhibit indicates that this is the desired configuration, and therefore the correct command to issue on the Juniper device would be to set the priority to 0 on the relevant interfaces.

Question 2

Which two statements ate correct about the community BGP attribute on a Junos device? (Choose two.)

AThe community attribute is a mandatory BGP attribute.

BIf the community attribute is present, it is ignored and deleted in the BGP updates.

CIf the community attribute is present, it should be passed unchanged in the BGP updates.

DThe community attribute is an optional BGP attribute.

Correct answer: C, D

The community attribute in BGP is an optional transitive attribute. It is not mandatory for BGP operations, but when it is present, it should be passed unchanged to other BGP peers unless explicitly modified by a routing policy. The community attribute is used to group destinations in a certain way, often to apply routing policies to those destinations collectively.

Question 3

An OSPF router does not have a router ID configured.

In this scenario, which statement is correct about the router ID?

AThe Junos OS will use the IP address assigned to the interface with the lowest MAC address.

BA router ID will not be assigned until it is manually configured.

CThe Junos OS will use the IP address assigned to the loopback interface for the router ID.

DThe Junos OS will use the IP address assigned to the Interface with the highest priority.

Correct answer: C

The router identifier is used by BGP and OSPF to identify the routing device from which a packet originated. The router identifier usually is the IP address of the local routing device. If you do not configure a router identifier, the IP address of the first interface to come online is used. This is usually the loopback interface. Otherwise, the first hardware interface with an IP address is used

In OSPF, if a router ID is not manually configured, Junos OS will automatically select the router ID based on the highest IP address of any of the router's loopback interfaces. If no loopback interface exists, the highest IP address of any active interface will be used. Therefore, answer C is correct.

Question 4

Which statement is correct about the FE80;:/10 prefix?

AThis prefix range is used for the link local address.

BThis prefix range is used on the loopback interface.

CThis prefix range is reserved for multicast applications

DThis prefix range is not reserved.

Correct answer: A

The FE80::/10 prefix is reserved for IPv6 link-local addresses. These addresses are auto-configured on all IPv6-enabled interfaces and can be used for communication within the local link (subnet) only.

Question 5

Which two statements are correct about the way that BGP propagates routes by default? (Choose two.)

AA route learned by EBGP will be re-advertised to IBGP peers.

BA route learned by IBGP will not be re-advertised lo IBGP peers.

CA route learned by EBGP will not be re-advertised to IBGP peers.

DA route learned by IBGP will be re-advertised to IBGP peers.

Correct answer: A, B

By default, BGP will propagate routes learned from EBGP peers to other IBGP peers. However, due to the BGP split-horizon rule, routes learned from one IBGP peer are not re-advertised to another IBGP peer. This behavior is designed to prevent routing information loops within the same AS.

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?
