JN0-681 Online Practice Questions and Answers

You are logged in to Leaf 1. When examining the routing table, you notice that you have no routes from Leaf 2.

Referring to the exhibit, which two commands would you use to troubleshoot the problem? (Choose two.)

A. From Leaf 2, issue the show route advertising-protocol bgp 172.16.1.2 command.

B. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.1 command.

C. From Spine 1, issue the show route advertising-protocol bgp 172.16.1.2 command.

D. From Leaf 1, issue the show route receive-protocol bgp 172.16.1.1 command.

You host a multitenant data center that runs VMware. You must perform deep packet inspection on all inter-tenant traffic that is flowing between the VMs within the same hypervisor. Your solution must provide the security services without needing to leave the physical device.

In this scenario, what should you do to solve this problem?

A. Use separate vSwitches to isolate each tenant's networks and use IP tables to evaluate inter-tenant traffic.

B. Use VLANs to isolate each tenant's networks and use an SRX Series device to evaluate inter-tenant traffic.

C. Use a vMX device to isolate each tenant's networks and use with firewall filters to evaluate inter-tenant traffic.

D. Use separate vSwitches to isolate each tenant's networks and use a vSRX Series device to evaluate inter-tenant traffic.

Which two statements describe MAC address learning for VPLS and EVPN? (Choose two.)

A. EVPN learns MAC addresses in the data plane.

B. VPLS 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.

What are three functions supported by the Contrail Command user interface? (Choose three.)

A. enabling VM-to-BMS bridging

B. onboarding of an IP Fabric

C. configuring management domains

D. integrated syslog collector

E. creating virtual networks

You are asked to deploy 20 QFX Series devices using ZTP. Each QFX5100 requires a specific FTP

server.

In this scenario, which two components must you configure on the DHCP server? (Choose two.)

A. the IP address of the FTP server

B. the MAC address of the FTP server

C. the IP address of each QFX5100

D. the MAC address of each QFX5100

You are configuring an IP Fabric in your data center and you are trying to load-balance traffic across multiple equal-cost BGP routes. You have enabled multipath, but the traffic is not being load-balanced.

Referring to the exhibit, what will solve this problem?

A. You should apply the load-balance policy as an import policy to the forwarding table.

B. You should apply the load-balance policy as an import policy for the BGP neighbor.

C. You should apply the load-balance policy as an export policy to the forwarding table.

D. You should apply the load-balance policy as an export policy to the BGP neighbor.

Which two statements describe an IP fabric? (Choose two.)

A. Open standards allow for vendor interoperability.

B. Each leaf should have a connection to each spine.

C. xSTP protocols should be used to prevent loops.

D. Traffic should always follow a single path.

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 a load-balancing policy applied to the forwarding table.

B. Use multipath multiple-AS.

C. Use advertise-inactive.

D. Use multihop.

Which EVPN route type prevents BUM traffic from looping back to a multihomed host?

A. IP prefix route

B. Ethernet autodiscovery route

C. Ethernet segment route

D. inclusive multicast-Ethernet tag route

Which two statements are true about Virtual Chassis? (Choose two.)

A. The request virtual-chassis mode fabric reboot command will set the Virtual Chassis to fabric mode with similar devices.

B. The request virtual-chassis mode fabric reboot command will set the Virtual Chassis to mixed mode.

C. By default, Junos switches are in a non-mixed mode Virtual Chassis.

D. By default, Junos switches are in mixed mode Virtual Chassis.
