Referring to the exhibit, each leaf node is a QFX5100 acting as a VXLAN Layer 2 Gateway using EVPN signaling. Leaf 2 and Leaf 3 are both attached to the same EVPN Ethernet segment. Leaf 2 has been elected the designated forwarder for VLAN 200 on that Ethernet segment.
In this scenario, which two actions will Leaf 1 perform with the broadcast Ethernet frame received from Host A? (Choose two.) A . Leaf 1 will strip the VLAN tag from the Ethernet frame before encapsulating it in VXLA C . Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to both Leaf 2 and Leaf 3. D . Leaf 1 will change the VLAN tag of the Ethernet frame to 200 before encapsulating it in VXLA F . Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to Leaf 2 only.
You have built a mixed-mode VCF consisting of two QFX5100-24Qs as spines, two QFX5100-48S as leaf nodes, and one EX4300 as a leaf node. The VCF is working for all devices, except the EX4300 40GbE fabric links will not join the VCF.
In this scenario, what must be corrected to solve the connectivity problem? A . Reboot all of the VCF members. B . Power off all of the VCF members and power up the spines before powering up the leafs. C . Zeroize the EX4300, cleat all the tables with the clear ethernet-switching tables command on all members, and reissue the request virtual-chassis mixed-mode command. D . Turn off authonegotiation on the EX4300 and the attached spine interfaces, and then use the request virtual-chassis vc-port set command on the spine ports connected to the EX4300.
A customer has built a VXLAN using an EVPN signaling infrastructure with remote facilities with VXLAN using EVPN signaling connected to the Internet. The customer notices that the network is completely stable with no protocol errors in the underlay or overlay. The customer, however, cannot pass any application data across the network.
Which statement would explain the intermittent loss? A . There is an LACP key mismatch. B . The MTU is exceeded. C . The routing protocol authentication has failed. D . The BPDU protection is invoked.
Your server administrator asks you to preserve the inner VLAN tags of the frames coming from a Layer 2 VXLAN Gateway of the EVPN-enabled segment.
Which two parameters must you add to the configuration to allow the VLAN tag to be passed? (Choose two.) A . layer2-protocol-tunneling B . decapsulate-accept-inner-vlan C . dotlq-tunneling D . encapsulate-inner-vlan
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. Leaf 1 and Leaf 2 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? A . Edge1 must be configured for MP-BGP using EVPN signaling. B . Edge1 must be configured for MP-BGP using L3VPN signaling. C . Edge1 must be configured for BGP labeled unicast on its PE1-facing interface. D . Edge1’s routing table must contain an IP route to both Leaf1 and Leaf2.
Assumption here that the MPLS backbone network offers EVPN; this is the most fully-featured solution. This could also be achieved via C; BGP-LU shared with the provider, basically extending MPLS down to the Edge1+2 routers; this is less ‘risky’ for the MPLS backbone operator. B and D are ignoring EVPN/VXLAN components and refer to traditional Layer 3 IP routing.
You are implementing a Virtual Chassis using QFX5100s and EX4300s in your data center.
In this scenario. which three hardware capabilities are affected? (Choose three.) A . usable VCP connections limited to 10GbE B . MAC table size C . number of usable ports per member D . number of supported routing instances E . maximum number of firewall filters
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? A . approximately 25% B . approximately 75% C . approximately 33% D . approximately 66%
Explanation:Leaf-to-leaf communication has 3 paths via each Spine node; lose 1 Spine, lose 1 path, i.e. 33%
In a preprovisioned mixed Virtual Chassis, which statement is correct about converting a 40Gbps QSFP+ to a Virtual Chassis port in an EX4300? A . LLDP is enabled on that interface. B . LLDP is disabled on that interface. C . One end of the link is configured as a Virtual Chassis port. D . Both ends of the link have the default configuration.
You are developing an EVPN service between your data centers to enable Layer 2 stretch and Virtual Machine Traffic Optimization (VMTO) operations.
In this scenario, which action must be performed on the IRB interface to accomplish this task? A . Configure the same IP address and let the MAC address be dynamically assigned on each P C . Configure the same IP address and the same MAC address on each P E . Configure different IP addresses but the same MAC address on each P G . Configure different IP addresses and different MAC addresses on each P
Referring to the exhibit, which hardware change would be made to the IP Fabric to ensure an exact 4:1 oversubscription ratio? A . Upgrade the fabric links to 100Gb C . Add two leaf nodes to the IP Fabric. D . Add three leaf nodes to the IP Fabric. E . Add a spine node to the IP Fabric.
