Verified JN0-363 Exam Dumps Q&As – Provide JN0-363 with Correct Answers

Q77. You are bringing a new network online with three MX Series devices enabled for STP. No root bridge priority has been configured. Which statement is true in this scenario?

The device with the lowest MAC address will be elected as the root bridge.

The device with the highest MAC address will be elected as the root bridge.

The device with the lowest numerical lo0 IP address will be elected as the root bridge.

The device with the highest numerical lo0 IP address will be elected as The bridge.

https://supportportal.juniper.net/s/article/EX-Identify-the-Root-Bridge-in-a-Spanning-Tree-STP-network?langua The root bridge in a spanning-tree network is the bridge with the smallest or the lowest bridge ID.
In the absence of a manually configured priority, the Spanning Tree Protocol (STP) elects the root bridge based on the lowest bridge ID, which is a combination of the priority and the MAC address. The device with the lowest MAC address will have the lowest bridge ID and thus be elected as the root bridge.

protocol

source port

destination port

source address

destination address

Q80. You are asked to assign interface xe-1/0/5 to a virtual switch. What must be accomplished to complete the configuration?

Interface xe-1/0/5 must be added to routing-instance sw-1 vlan_2.

Interface xe-1/0’5 must be a trunk port.

Interface xe-1/0/5 must be added to routing-instance sw-1.

An IRB interface must be configured to routing-instance sw-1 vlan_2.

Q81. Which two Layer 2 protocols are supported on MX Series devices? (Choose two.)

BGP

RIP

RSTP

MSTP

Q82. Click the Exhibit.

You have configured the IBGP group shown in the exhibit. However, committing your configuration fails.
Which parameter should you add to the IBGP group configuration to correct the problem?

Type external

Type internal

Export <policy name>

As -override

Q83. You are asked to assign interface xe-1/0/5 to a virtual switch. What must be accomplished to complete the configuration?

Interface xe-1/0/5 must be added to routing-instance sw-1 vlan_2.

Interface xe-1/0/5 must be a trunk port.

Interface xe-1/0/5 must be added to routing-instance sw-1.

An IRB interface must be configured to routing-instance sw-1 vlan_2.

Q84. You are asked to create connections between routing instances on the same Junos device and route between the connected Instances. What are two ways to accomplish this task? (Choose two.)

Use physical interfaces.

Use an IRB interface.

Use logical tunnel interfaces.

Use loopback interfaces.

Q85. Exhibit

You are advertising a summary route that represents your local network (172.20.0.0716) to both ISP A and ISPB. You want to influence all traffic sent to you from ISP C to go through R2.
How would you accomplish this task?

On R1, prepend your AS number three times on the 172.20.0.0/16 route when advertising It to ISP 1.

On R1, change the local preference value to 250.

On R2. prepend your AS number three times on the 172.20.0.0/16 route when advertising it to ISP 2.

On R2, change the local preference value to 50.

Q86. Click the Exhibit button. What does IS-IS/18 mean in the output displayed in the exhibit?

These routes are internal Level 1 routes.

These routes are internal Level 2 routes.

These routes are external Level 1 routes.

These routes are external Level 2 routes.

Q87. What are three well-known mandatory BGP attributes? (Choose three.)

next hop

origin

community

MED

AS path

There are four categories of BGP attributes:
Well-known mandatory: Recognized by all BGP peers, passed to all peers, and present in all Update messages. Well-known mandatory attributes include:- Next- hop- Origin- AS PATH Well-known discretionary: Recognized by all routers, passed to all peers, and optionally included in the Update message. Well-known discretionary attributes include:- Local Preference – Atomic Aggregate Optional transitive: Possibly recognized by BGP routers and passed to BGP peers. Optional transitive attributes are marked as partial when not recognized.
Optional transitive attributes include: – Aggregator – Community
Optional non-transitive: Possibly recognized by BGP routers but not passed to peers. Optional non-transitive attributes include:- Multi-exit discriminator (MED) – Originator ID -Cluster-ID

Q88. Which Layer 2 mechanism logically groups network nodes into separate broadcast domains?

IS-IS levels

OSPF areas

VLAN

IP subnets

Q89. Click the Exhibit.

Referring to the exhibit, which IS-IS router will be selected as the DIS?

Router 1

Router 4

Router 2

Router 3

Q90. An OSPF router does not have a router ID configured.
In this scenario, which statement is correct about the router ID?

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

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

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

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

Q91. Click the Exhibit button. In the exhibit, all routers are sending routes to Router B.Which routes will be advertised from Router B to Router E?

BGP routes learned from Router A only

BGP routes learned from Router D only

BGP routes learned from Routers A and C only

BGP routes learned from Routers A, C, and D only

Q92. You are deploying an RSVP-based MPLS network in your core. You must ensure that your LSPs are continually analyzing the usage levels and recalculating the best LSP. You also want to ensure that a minimal amount of traffic is lost when an LSP is re-signaled without user intervention.
Which two features must be enabled in this scenario? (Choose two.)

adaptive

MPLS fast reroute

class of service

auto-bandwidth

Q93. Exhibit

Referring to the exhibit, which two statements are correct? (Choose two.)

Prefixes in Level 1 will be redistributed to Level 2.

Prefixes in Level 2 will be not redistributed to Level 1.

Prefixes in Level 1 will not be redistributed to Level 2.

Prefixes in Level 2 will be redistributed to Level 1.

In IS-IS, Level 1 routes are usually contained within the same area and Level 2 routes are used to interconnect different areas. By default, routes from Level 1 are redistributed into Level 2, and vice versa, to ensure reachability between areas.

Juniper Networks Technical Documentation on IS-IS
By default, IS-IS protocol leaks routing information from a Level 1 area to a Level 2 area. However, to leak routing information from a Level 2 area to a Level 1 area, an export policy must be explicitly configured.
