Question 1

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?

AChange the design to use centralized routing because HPE Aruba CX switches cannot support DHCP relay with distributed routing

BFor every SVI, assign a unique actual IP address, different from the active gateway IP address

COn each VTEP switch, create a loopback interface in the shared VRF with the same IP on both switches in a VSX pair

DOn each VTEP switch, create a loopback interface in the tenant-a VRF with a different IP on both switches in a VSX pair

Answer : C

Question 2

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

AThe forwarding interface for the MAC address is the local interfaces

BThe forwarding interface for the MAC address is the tunnel to the next hop VTEP

Answer : B

Question 3

Which of these protocols carries commands for reading from/writing to storage over a TCP/IP session?

ARDMA

BiSCSI

CNVMeoF-RDMA

DFCoE

Answer : B

Question 4

Which of these is a key CX EVPN VXLAN capability?

ASupport Asymmetric Integrated Routing and Bridging (IRB)

BOnly supports centralized gateway to route between overlay networks

CARP suppression

DDoes not forward broadcasts, unicasts, and multicast (BUM) traffic in the overlay

Answer : C

Question 5

One of your customers has the following:

2-Tier L2 Design

* 8325 32x100G Core Switches

* 8360 48x10G RJ-45 Access Switches

* 100G 5M DAC connections between Core and Access

Core Switches = VSX Pairs of 8325 32-port 100G switches (F-B airflow).

Access Switches = VSX Pairs of 8360-48xBaseT switches (F-B airflow).

Each Core Switch pair uses the following for VSX:

* 2 x 100G QSFP28 1M DACs for ISL

* 1 x 100G QSFP28 1M DAC for Keepalive

Each Access Switch pair uses the following for VSX:

* 2 x 100G QSFP28 1M DACs for ISL

* 1 x 10G RJ45 cable for Keepalive

Each Core switch has 29 remaining available 100G QSFP28 interfaces for access switch connectivity.

This solution uses 1x100G QSFP28 5M DAC from each access switch to each core switch.

This solution can scale up to a maximum of 14 racks using the same subscription rates.
