Which technology uses LLDP TLVs to tell connected devices information such as the correct queue for PFC?

You are designing a Data Center with Spine Leaf architecture. Spine Switches are 8400 with 12 QSFP28 ports (F-B airflow) and leaf switches are 8360 switches stacked with VSX in each rack. The Customer sent you the following Specifications Each Spine Switch uses:

* 1 x 100G QSFP28 5M DACs to each Leaf switch Each Leaf Switch uses:

* 1 x 100G QSFP28 5M DACs to each Spine switch

* 2 x 100G 1M DAC for ISL

* 1 x 25G SFP28 DAC for Keep alive

What is the scalability in this design?

How many Aruba 100G QSPF28 LC ER4L 40KM SMF Transceivers are allowed on Aruba CX 8325?

In one of the spine and leaf designs, VMware vSphere is used including VMware NSX. OSPF is used for routing protocol across the spine and leaf topology. What do you need to consider in this design? (Select three)

Depending on a switch's role in the topology, the demands on various tables differ. Several HPE Aruba CX switch models support different profiles, each of which optimizes the correct table for a switch with the corresponding role:

You need to design a network that supports transmitting RDMA traffic over multiple IP hops. Which protocols must the switches support? (Select all that apply.)

A customer currently has a three-tier architecture in which aggregation switches are the default gateways. Pairs of aggregation switches use VRRP. You are migrating to an L2 two-tier architecture in which the core switches are the default gateways. How should you migrate the default gateway functionality?

What is true about the QSFP-DD MPO-12 eDR4 transceiver?

In Spine and Leaf Design that involves the following:

* 8360 12-P 100G Spine Switches

* 8360 48-P 10G RJ45 Leaf Switches

* 100G SR4 Optical connections between Spine and Leafs

Spine Switches = 8360 12-port 100G QSFP28 (F-B airflow)

Each Spine Switch uses:

* 1 x 100G QSFP28 SR4 Optic to each Leaf switch

Each Leaf Switch uses:

* 1 x 100G QSFP28 SR4 Optic to each Spine switch

* 2 x 100G 1M DAC for ISL

* 1 x 10G RJ45 for Keepalive

Each Spine switch has 4 available 100G QSFP28 interfaces. What is the solution scalability?
