Question1: Spine 1 and Spine 2 are MX Series devices configured to act as redundant VXLAN Layer 3 Gateways using the virtual-gateway-address 10.0.1.254 statement.

Referring to the exhibit, how will a spine node react to receiving the ARP request from Host A?

Question2: You are asked to design a deployment plan for a large number of QFX Series switches using zero touch provisioning (ZTP). The ZTP deployment plan must ensure all switches are upgraded to the desired software version.
Which DHCP option are suboption combination would be used to accomplish this task?

Question3: You are establishing an IP Fabric where your QFX10002-72Q spine devices are connecting to leaf devices. Each leaf is a Virtual Chassis comprised of ten EX4300s.
What is the maximum number of leaf devices supported in this scenario?

Question4: You are deploying an IP Fabric in your new data center. You need to ensure that your servers have multiple active/active links for redundancy and load balancing.
What are two methods to accomplish this goal? (Choose two.)

Question5: You are deploying MC-LAG as shown in the exhibit.

Which statement is correct when using active/standby mode?

Question6: Referring to the exhibit, which two MAC addresses are learned from the local side of the MC-LAG link?

Question7: When QFX5100 series and EX4300 series are in a Virtual Chassis, which two statements are true? (Choose two.)

Question8: Which two options are network consideration for common VXLAN deployment? (Choose two.)

Question9: Which statement is true about a Data Center Interconnect over an IP network?

Question10: You are having management connectivity problems with a mixed-mode Virtual Chassis.
Which statement is correct in this scenario?

Question11: Referring to the exhibit, PE1 and PE2 are acting as MPLS Layer 3 VPN PEs to provide the DCI between DC1 and DC2, which are IP Fabrics. Leaf1 and Leaf2 are QFX5100 Series devices acting as VXLAN Layer 2 Gateways using EVPN signaling for the same VXLAN segment.

Which statement is correct about the Edge1 device in this scenario?

Question12: Which statement describes a Juniper Virtual Chassis Fabric?

Question13: Referring to the exhibit, which hardware change would be made to the IP Fabric to ensure an exact 4:1 oversubscription ratio?

Question14: You are performing an in-service software upgrade (ISSU) on an QFX5100 Series device.
Which two statements are correct in this scenario? (Choose two.)

Question15: Referring to the exhibit, VMs on Server-1 are sending traffic to VMs on Server-2. All VCPs in the VCF have 40Gbps of bandwidth available and automatic fabric trunking is bundling multiple VCPs together.

Which statement is correct in this scenario?

Question16: Which two statements are correct when performing a unified ISSU? (Choose two.)

Question17: In a preprovisioned mixed Virtual Chassis, which statement is correct about converting a 40Gbps QSFP+ to a Virtual Chassis port in an EX4300?

Question18: You are configuring VXLAN on a network of QFX5100s, and are using the set vlans vlan100 vxlan command: unreachable-vtep-aging-timer 600
What does this command do?

Question19: Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN 100 using PIM-SM signaling.

What will cause R2 to send a (*.G) PIM Join towards the RP?

Question20: Which statement is correct about EVPN Type 2 routers?

Question21: Which statement is valid for EVPN multihoming CE1 to PE1 and PE2 as shown in the exhibit?

Question22: Referring to the exhibit, SW-3 and SW-4 have been configured for mixed-mode VCF and added to the VCF. After cabling the new devices into the VCF, you notice that SW-3 automatically joins the VCF, whereas SW-4 does not.

Why are SW-3 and SW-4 behaving this way? (Choose two.)

Question23: You are building an EVPN Data Center Interconnect. You must support multiple VLANs in a single EVPN instance.
Which parameter provides this functionality?

Question24: Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN 100 using PIM-SIM signaling.
R1 currently has an entry for Host B in its MAC table.

What will R1 do in response to receiving the ARP packet from Host A?

Question25: Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN 100 using PIM-SM signaling. R2 currently has only the (*.G) state established for VNI 5100.

Which event will cause R2 to establish the (S,G) state for VNI 5100 using R1 as the multicast source?

Question26: You created an IP Fabric based on IBGP. You noticed that ECMP load sharing is not working. In this scenario, what is the problem?

Question27: Which three BGP messages pass EVPN information between devices? (Choose three.)

Question28: You have configured a DHCP server for ZTP as shown in the exhibit.

Your network contains EX2200 and QFX5100 devices, however, only the EX2200s are receiving the baseline configuration file. You want to ensure that all of the switches in your network receive the baseline configuration file.
Which actions will satisfy this requirement?

Question29: What is the endpoint of a VXLAN tunnel?

Question30: You are building a mixed-mode Virtual Chassis with two QFX5100-24Qs, four QFX3500-48s, two EX4600-40Fs and two EX4300-48Ts. The Virtual Chassis will not provision.
In this scenario, which statement is correct?

Question31: You have an EBGP-based IP Fabric.
Why do you need an export policy on each leaf in this scenario?

Question32: Referring to the exhibit, what is the MAC address of the IRB interface on router PE1?

Question33: A customer has a 3-stage Clos architecture with three spine devices as shown in the exhibit.

If a single spine device fails, what percentage of the remaining bandwidth will be available from leaf node to leaf node?

Question34: Which two statements are true regarding EVPN Route Distinguishers? (Choose two.)
