In a multi-AS underlay design:

You are involved in a 2-Tier L2 Data Center Design with the following details: * CX 8325 100G Core Switches * CX 10000 48-P 25G Access Switches * 100G SR4 Optical connections between Core and Access In this design, both the Core Layer and Access Layer consist of pairs of switches configured in VSX for HA. Core Switches = VSX Pairs of CX 8325 32-port 100G switches (B-F airflow) Each pair uses: * 2 x 100G QSFP28 1M DACs for ISL * 1 x 100G QSFP28 1M DAC for Keepalive * 2 x 100G QSFP28 SR4 Optic to each access switch Each Core switch has 13 available 100G QSFP28 interfaces. What is the maximum number of racks supported by this design?

Question 72

What is true about the VSX switches in EVPN VXLAN?

You should make the two switches in the VSX pair operate as a single logical VTEP

VSX stacking and EVPN VXLAN are mutually exclusive

Each member of the VSX acts as standalone from the EVPN VXLAN perspective

Question 73

You are designing a network based on HPE Aruba CX 10000 switches. Which is a valid reason to recommend manually pinning two VRFs to the same DSM?

That switch forwards traffic in both VRFs to a third-party firewall for routing

You have selected this switch to act as the border leader for a multi-fabric EVPN VXLAN design

You have planned similar policies for those VRFs and want to minimize the load on the switches' rules table

That switch leaks routes between those VRFs

Question 74

Loopback addresses are very useful for troubleshooting and for device management. What is true about the loopback interfaces?

Not required for underlay connectivity using OSPF

Should be avoided if NSX is used as an overlay

Not required for EVPN VXLAN

They need to be advertised for underlay connectivity when using OSPF

Question 75

You created a formal proposal and quote for a customer's data center network refresh. What is some other support information that you should include? (Select two)

A list of IP addresses that you plan to configure on the switches

No need to include any of these as the proposal is not the place to educate the customer on them

HPE Aruba networking recommends including a block diagram with proposals

A list of VLANs that you plan to configure on the switches

Question 76

What is one difference between a QSFP28 LC BiDi transceiver and a QSFP28 MPO SR4 transceiver?

The BiDi transceiver uses fewer fiber strands than the SR4 transceiver

The BiDi transceiver supports splitting the bandwidth into multiple lower bandwidth links

The BiDi transceiver requires single-mode fiber, while the SR4 transceiver supports multi-mode

The BiDi transceiver supports lower bandwidth than the SR4 transceiver

Leaf switches that act as centralized routers for the overlay

Leaf switches that act as distributed routers for the overlay

Spine switches

Border leaf switches

Question 80

In preparation for the deployment, what statement is correct from the below?

It is best if you migrate Layer 2 functionality (e.g., VLAN tagging on uplinks) and Layer 3 function (e.g., default gateways) simultaneously

If you have spent good time on your design, there is no need to have any rollback plan

It is not best practice to build the new network in parallel to the existing network

Migrate Layer 2 functionality (e.g., VLAN tagging on uplinks) then cut over to Layer 3 function (e.g., default gateways)
