Juniper JN0-682 問題集

質問 1：
Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load- share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B.

Which two actions must be performed to accomplish this task? (Choose two.)
A. Use multihop
B. Use advertise inactive
C. Use multipath multipath-As
D. Use a load-balancing policy applied to the forward table
正解：C,D

質問 2：
You are troubleshooting a connectivity issue across a VXLAN overlay network. In the exhibit, you are using the ping overlay command from a local VTEP residing on a OFX 5120 to a remote VTEP residing on a separate QFX5120.




What is the problem in this situation?
A. VXLAN VN1100 is not configured on both end points.
B. VXLAN VN1100 is not configured on the local VTEP
C. VXLAN VN1100 is not configured on the remote VTEP.
D. The VXLAN controller is down.
正解：C

質問 3：
You manage a data center with a 5-stage EVPN-VXLAN IP fabric. You notice that there are suboptimal paths used between the leaf and spine as well as the spine and super spine. What is one way to solve this issue?
A. Configure the leaf layer so that all leaf devices share the same ASN.
B. Configure the spine layer so that all spines in a POD share the same ASN.
C. Configure the super spine and spine layers to all use the same ASN.
D. Configure the spine layer for EBGP and the leaf layer for IBGP
正解：B

質問 4：
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.)
A. The MAC address associated with 10.1.1.1/24 and 10.1.1.2/24 will be same when advertised to leaf3.
B. The ESI assigned to the host1 link must be the as the ESI assigned to the leaf2 host1 link.
C. Traffic from IP address 10.1.1.1/24 must traverse the VXLAN network to reach IP address 10.1.1.2/24
D. The connection host1 to devices leaf1 and leaf2 must be configuration a LAG.
正解：B,D

質問 5：
Which protocol replicates forwarding information between MC-LAG peers?
A. VRRP
B. LLDP
C. VCCP
D. ICCP

質問 6：
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.)
A. All BGP routes advertised by a leaf device will be accepted on the spine devices.
B. A leaf device will reject all BGP routes received from the spine that were originated from another leaf device.
C. All BGP routes advertised by a leaf device will be rejected on the spine devices.
D. A leaf device will accept all BGP routes received from the spine that were originated from another leaf device.
正解：A,D

質問 7：
You have a two spine and four leaf CRB topology and you must ensure that the hosts connected to the leaf devices have reachability to all IRB interface addresses, including the local spine IRB addresses, and the virtual gateway address.
Which two configuration parameters must be used to accomplish this task? (Choose two.)
A. Configure a spine-to-spine EVPN peering as part of the routing instance.
B. Configure proxy-macip-advertisement under the IRB interface.
C. Configure a spine-to-spine BGP peering as part of the overlay.
D. Configure virtual-gateway-accept-data under the IRB interface.

A. EVPN learns MAC addresses in the data plane
B. EPLS learns MAC addresses in the control plane
C. VPLS learns MAC addresses in the data plane
D. EVPN learns MAC addresses in the control plane
