Question 16

How many Virtual Network Identifiers are supported by the VXLAN specification?

Accepted Answer

VXLAN supports 24-bit Virtual Network Identifiers (VNIs), allowing for 16,777,216 unique identifiers.

Question 17

What is Adaptive Segmentation?

Accepted Answer

Adaptive Segmentation refers to the ability of VMTracer to dynamically create VLANs based on the VLANs currently in use by VMs. This allows for more efficient network usage and simplifies network management. The other options listed (B, C, and D) refer to different networking capabilities, not necessarily related to Adaptive Segmentation.

Question 18

If you were build a large-scale cloud-based architecture that required 100% efficient cell-based fabric, Virtual Output Queuing (VOQ), and 3.84 Tbps capacity per slot, which Arista switch series would be the correct choice?

Accepted Answer

The Arista 7500E switch series is the only one out of the options listed that can provide 3.84 Tbps capacity per slot, as well as support for 100% efficient cell-based fabric and Virtual Output Queuing (VOQ). The 7010T and 7300 switches have maximum capacities of 1.28 Tbps and 2.56 Tbps, respectively, while the 7150 series does not support VOQ. Therefore, the best choice is the Arista 7500E.

Question 19

Given the following output, which of the following have you likely configured?

Accepted Answer

The output is a hardware address in the format used by Advanced Mirroring with Packet Truncation, indicating that this feature has been configured.

Question 20

With VXLAN, a table is created that contains all the known VXLAN Tunnel Endpoints within a VXLAN VNI. What is this table called?

Accepted Answer

The table that contains all the known VXLAN Tunnel Endpoints within a VXLAN VNI is called the flood-list. It is used to forward traffic to the correct destination endpoint.
