Question 1
2-Tier L2 Design • 6400 100G Core Switches • 8320 48-P 10G RJ45 Access Switches • 40G DAC connections between Core and Access Core Switches = VSX Pairs of 6400 switches (each with 2 x 12-port QSFP28 100G modules) Each pair uses: • 2 x 1M 100G DAC for ISL • 1 x 1M 100G DAC for Keepalive • 2 x 5M 40G DAC to each access switch Each Spine switch has 5 x 100G interfaces available. This solution could scale to a maximum of:
A. 7 total racks using same subscription rates
B. 10 total racks using same subscription rates
C. 12 total racks using same subscription rates
D. 15 total racks using same subscription rates

Question 2
You are setting up a single EVPN VXLAN fabric for a data center. A customer has one ESXi cluster in racks 1-3 that uses VLAN 10 for VMs in subnet 10.1.10.0/24. The customer has another ESXi cluster in racks 4-6 that uses VLAN 10 for VMs in subnet 10.2.10.0/24. Which is correct?
A. You can map VLAN 10 to different VNIs on the same switches if you place VLAN 10 in multiple VRFs
B. You must tell the customer to change the VLAN ID in racks 4-6 to a unique ID
C. You can use subnets rather than VLANs for VNI mappings so you can use the same configuration everywhere
D. You can map VLAN 10 to one VNI on switches in racks 1-3 and to a different VNI on switches in racks 4-6

Question 4
You want to implement distributed firewall policies that micro-segment VM-to-VM traffic, including within the VLAN and same host. The VMs should be able to send traffic on permitted TCP ports, but other traffic should be dropped (hosts are isolated). What are two requirements? (Select two.)
A. SVI 10 on the switch has IP local ARP proxy enabled on it
B. The VMware host is configured to implement a local firewall
C. VLAN 10 is converted to a PVLAN on the switch only. The VMs are placed in an isolated VLAN
D. VLAN 10 is converted to a PVLAN on the switch and VMware hosts. The VMs are placed in an isolated VLAN

Question 5
In Routing design for a two-tier topology between the data center and other parts of the network, select the best option from below
A. You should not use VSX LAGs for these connections
B. Don't use Layer 3 links
C. Establish point-to-point links using individual /29 subnets

Question 6
You are adding EVPN VXLAN to an L3 spine and leaf topology that uses OSPF for the underlay. You plan to use a single BGP AS. Which design for EVPN neighbors is correct?
A. Leaf switches should establish iBGP sessions with other leaf switches using their VXLAN loopback IPs. Route reflectors are not required
B. The border leaf switches should act as route reflectors and specify the leaf switches’ VXLAN loopback IPs as route reflector clients
C. At least one spine switch should act as route reflector and specify the leaf switches’ unique loopback IPs as route reflector clients
D. Leaf switches should establish iBGP sessions with spine switches on their actual P2P link IP addresses. Route reflectors are not required

Question 8
Two VMs on the same ESXi host are assigned to an isolated VLAN 2001 (primary VLAN 1001). The host connects to an HPE Aruba CX 10000 switch on an access port. The switch supports the same PVLAN settings. VM 1 sends traffic to VM 2. Which policy or policies does the switch apply (assuming that they exist)?
A. Egress policy on VLAN 1001
B. No policies because the traffic remains local to the ESXi host
C. Ingress and egress policy on VLAN 1001
D. Ingress policy on VLAN 1001

Question 12
You are planning to use distributed routing for overlay subnets in an EVPN VXLAN fabric. The customer needs to provide DHCP addresses to some VMs in the tenant-a VRF. The DHCP server is in the shared VRF. What is one step you should take?
A. Change the design to use centralized routing because HPE Aruba CX switches cannot support DHCP relay with distributed routing
B. For every SVI, assign a unique actual IP address, different from the active gateway IP address
C. On each VTEP switch, create a loopback interface in the shared VRF with the same IP on both switches in a VSX pair
D. On each VTEP switch, create a loopback interface in the tenant-a VRF with a different IP on both switches in a VSX pair

Question 14
BGP EVPN type 2 routes advertise MAC addresses of clients connected to VNIs on this VTEP. Other VTEPs use this information to populate the MAC address tables for the VLAN associated with the VNI. VXLAN does not rely on MAC forwarding to establish connectivity
A. The forwarding interface for the MAC address is the local interfaces
B. The forwarding interface for the MAC address is the tunnel to the next hop VTEP
