You are asked to manage the oversubscription ratio of your spine and leaf IP fabric. You determine that you are at a 3:1 ratio of downstream to upstream traffic and must achieve a 1:1 ratio.

In this scenario, which two actions would you take to achieve this goal? (Choose two.)

A. Increase the number of server-facing ports that each leaf node uses to carry traffic.

B. Reduce the number of server-facing ports that each leaf node uses to carry traffic.

C. Increase the number of spine nodes in your design.

D. Reduce the number of leaf nodes in your design.

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.

Referring to the exhibit, DC1 and DC2 have a DCI across a service provider WAN connection. Host1 in DC1 must have Layer 2 connectivity to host2 in DC2. A VXLAN tunnel must be created between VTEP1 and VTEP2.

In this scenario, which statement is true?

A. The service provider WAN connection cannot be an MPLS-based WAN connection.

B. VXLAN Layer 3 gateway must be provisioned at the Super Spine layer.

C. A route to the loopback address on VTEP2 must be present on VTEP1.

D. VTEP1 and VTEP2 must peer using IBGP.

You want to configure redundant Layer 3 gateways.

In this scenario, which two Juniper best practices would accomplish this task? (Choose two.)

A. configuring both IRB interfaces manually with the same MAC address.

B. allowing Junos to dynamically create the virtual IP address of the IRB interface.

C. configuring both IRB interfaces manually with the same IP address.

D. allowing Junos to dynamically create the virtual MAC address of the IRB interface.

You are asked to design a deployment plan for a large number of QFX Series switches using ZTP. The ZTP deployment plan must ensure all switches are configured with their designated configuration file.

Which DHCP option and suboption combination would be used to accomplish this task?

A. DHCP option 43 with a suboption of 00

B. DHCP option 66 with a suboption of 00

C. DHCP option 66 with a suboption of 01

D. DHCP option 43 with a suboption of 01

You are asked to enable plug-and-play for future line card switches in an active VCF without making any future Junos configuration changes. You are also required to ensure that all new line cards are automatically upgraded to the correct Junos version without any manual intervention.

In this scenario, which two actions will accomplish this task? (Choose two.)

A. Ensure that the newly inserted line card's MAC addresses are present in the DHCP configuration for ZTP.

B. Configure the auto-sw-update parameter on the VCF before inserting new line cards.

C. Set the Virtual Chassis as pre-provisioned before the line cards are inserted.

D. Set the Virtual Chassis as auto-provisioned before the line cards are inserted.

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.)

A. Change the ESI mode on PE1 to single-active.

B. Change the ESI mode on PE2 to all-active.

C. Change the ESI value on the PE2 device to 00:00:00:00:00:00:00:00:00:00.

D. Change the ESI value on the PE1 device to 00:22:44:66:88:00:22:44:66:88.

What are two valid types of VXLAN signaling? (Choose two.)

A. EVPN

B. RSVP

C. RSTP

D. MPLS

You want to ensure high availability of the Junos devices in your data center.

In this scenario, which three features would accomplish this task? (Choose three.)

A. Virtual Router Redundancy Protocol

B. Multiple Spanning Tree Protocol

C. dual Routing Engines

D. virtual private LAN service

E. graceful Routing Engine switchover
