The Juniper JN0-682 (Data Center, Professional (JNCIP-DC)) Certification Exam is a professional-level certification that validates the knowledge and skills of IT professionals in designing and deploying data center solutions using Juniper Networks technologies. The certification is intended for experienced IT professionals with a minimum of three years of experience in the data center field. Passing the exam demonstrates the candidate’s expertise in data center architecture, virtualization, automation, security, and storage. The JN0-682 certification is a valuable credential that can help IT professionals advance their careers and stand out in a competitive job market.

To take the JN0-682 exam, candidates must have a solid understanding of networking protocols, as well as experience with Juniper Networks data center products and technologies. It is recommended that candidates have at least two years of experience in data center networking before taking the exam.

NO.29 Referring to the exhibit, what effect does EVPN core isolation have?

Leaf 1 will send a pause frame to each connected host.

NO.30 Referring to the exhibit,

you have a data center in which only the spine devices are using EVPN and VXLAN. The leaf nodes are multihomed in active-active mode to the spine nodes through ESI LAG interfaces. In this design, a link failure on the interface connecting the spine nodes would also cause all traffic from the spine to the leaf nodes to drop.

the disable protocols evpn no-core-isolation command on the spine nodes

the set protocols evpn no-core-isolation command on the spine nodes

sub 50 ms failover times

NO.32 After configuring an IP fabric using EBGP as you protocol, you notice that not all of the routers are showing

properly.
In this scenario, which statement is true?

The routers have not been configured with the multipath multiple-as parameter.

The routers have not been configured using the bfd-1 Liveness-detection parameter.

The routers have not been configured using the multihop parameter.

The routers have not been configured using the add-path parameter

NO.33 You are configuring VXLAN. and you must ensure that all switches for the multicast groups advertise their existence and learn about other VTEPs In this scenario. which protocol will accomplish this task?

OSPF

EVPN

PIM

BOP

NO.34 Exhibit.

You are attempting to configure filter-based forwarding in your data center. All traffic from Host1 that is going to Host2 should be inspected by the data center firewall. You have verified that the traffic is being forwarded from router leaf L1’s VRF-1 to its INSPECT-VRF. however, the traffic is not reaching service L2.
Referring to the exhibit, which two steps should you take to troubleshoot the problem? (choose two.)

Examine the INSPECT-VRF.evpn 0 route table on L1 for a default route that will direct the traffic to L2.

Examine the INSPECT-VRF.inet. 0 route table on L1 for a default route that will direct the traffic to L2.

Ensure that VRF-1 and INSPECT-VRF route targets on L1 and L2 match.

Ensure that the route target in the INSPECT-VRF of L1 matches the route target of the INSPECT-VRF of L2.

NO.35 Which statement is true about the route shown in the exhibit?

The route target on this route is 1000

The route is an EVPN type-1 route.

The route uses a type-1 route distinguisher.

The VNI for this route is 304.

NO.36 An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. Host1 is a bare metal server, and is dual-homed to the network. The IP addresses 10.1.1.1/24 and
10.1.1.2/24 are assigned to the same physical NIC, and no virtualization is configured on the server.

In this scenario, which two statements are true? (Choose two.)

The MAC address associated with 10.1.1.1/24 and 10.1.1.2/24 will be same when advertised to leaf3.

Traffic from IP address 10.1.1.1/24 must traverse the VXLAN network to reach IP address 10.1.1.2/24

The connection host1 to devices leaf1 and leaf2 must be configuration a LAG.

The ESI assigned to the host1 link must be the as the ESI assigned to the leaf2 host1 link.

NO.37 What is the endpoint of a VXLAN tunnel?

DLCI

VTEP

LSR

VCF

NO.38 Your colleague has begun working on the base configuration for an active-active multihomed EVPN connection shown in the exhibit.

Which two actions will ensure a successful implementation? (Choose two.)

Change the ESI mode on PE2 to all-active

Change the ESI mode on PE1 to signal-active

Change the ESI value on the PE1 device to 00.22.44.88.00.22.44.66.88

Change the ESI value on the PE2 device to 00.00.00.00.00.00.00.00.00.00

NO.39 You are deploying a 3-stage Clos IP fabric in your data center. In this scenario, which statement is correct?

Each server-facing interface on a leaf node is always three hops away from other server-facing interfaces.

Each spine node must be physically connected to all other spine nodes.

There is an eight-spine node limitation.

No direct physical connections exist between leaf nodes.

NO.40 You are building an IP fabric underlay for your data center. You are asked to ensure that the two spine devices are in the same AS (65000) while the six leaf devices are in a different AS (65512).
In this scenario, which two statements are correct by default? (Choose two.)

All BGP routes advertised by a leaf device will be accepted on the spine devices.

A leaf device will accept all BGP routes received from the spine that were originated from another leaf device.

All BGP routes advertised by a leaf device will be rejected on the spine devices.

A leaf device will reject all BGP routes received from the spine that were originated from another leaf device.

NO.41 Referring to the exhibit, Host 1 and Host 3 have exchanged traffic.

In this scenario, which statement is true?

Leaf 2 learn Host 1’s MAC address through periodic updates from Spine 2

Leaf 2 learn Host 1’s MAC address when Host 3 learns Host 1’s MAC address.

Leaf 2 learn Host 1’s MAC address when Leaf 1 queries Host 1.

Leaf 2 does not learn Host 1’s MAC address until Host1 and Host2 send traffic to each other

NO.42 Referring to the exhibit, which two statements are correct? (Choose two.)

There are two tunnels to the remote endpoint.

The irb. 0 interface is the remote tunnel endpoint interface.

The source tunnel IP address is 192.168.100.11.

There is one tunnel to the remote endpoint.

NO.43 You are building an IP fabric underlay for your data center. You are asked to ensure that the two spine devices are in the same AS (65000) while the six leaf devices are in a different AS (65512). In this scenario, which two statements are correct by default? (Choose two.)

All BGP routes advertised by a leaf device will be accepted on the spine devices.

A leaf device will accept all BGP routes received from the spine that were originated from another leaf device.

All BGP routes advertised by a leaf device will be rejected on the spine devices.

A leaf device will reject all BGP routes received from the spine that were originated from another leaf device.

NO.44 You are evaluating which method to use for learning MAC addresses in your VXLAN network. Which statement is true in this scenario?

Multicast exchanges MAC addresses through data plane learning and is more reliable than EVPN.

EVPN exchanges MAC addresses through control plane learning and is more reliable than multicast.

EVPN exchanges MAC addresses through data plane learning and is more reliable than multicast.

Multicast exchanges MAC addresses through control plane learning and is not more reliable than EVPN.

NO.45 Which two statements describes an IP fabric? (Choose two.)

Each leaf should have a connection to each spine.
