Which of the following is not a DANZ feature?

Arista's Data ANalyZer (DANZ) is a suite of features designed for network visibility and monitoring. Its core capabilities include Tap Aggregation, which consolidates traffic from multiple network links; Agile Ports, which allow flexible configuration of ports as either input (tap) or output (tool); and Advanced Mirroring, which provides sophisticated filtering, replication, and modification of traffic sent to analysis tools. Multi-Chassis Link Aggregation (MLAG) is a high-availability feature within Arista's EOS that provides active-active redundancy for production network links. While a key Arista technology, MLAG's purpose is network resiliency, not traffic visibility, and it is therefore not considered a DANZ feature.

A. Tap Aggregation: This is incorrect. Tap Aggregation is a fundamental function of DANZ, used to collect and consolidate traffic from multiple network TAPs or SPAN ports for monitoring.

B. Agile Ports: This is incorrect. Agile Ports is a specific DANZ feature on certain platforms that allows ports to be dynamically configured as either tap (input) or tool (output) ports.

C. Advanced Mirroring: This is incorrect. Advanced Mirroring is a central component of the DANZ solution, offering capabilities beyond standard port mirroring, such as granular filtering and traffic manipulation.

1. Arista Networks, "Arista DANZ At-A-Glance" Document.

Reference: Page 1, "Key Features and Benefits" section. This document explicitly lists "Tap Aggregation for both L1 and L2/3" and "Advanced packet filtering, manipulation and load balancing" as core DANZ features.

2. Arista Networks, "Arista 7150 Series DANZ Configuration Guide."

Reference: Section 3.1, "Agile Ports." This section details the functionality of Agile Ports, stating, "Agile ports are ports that can be configured as either a tap port or a tool port." This confirms it as a DANZ feature.

3. Arista Networks, "EOS 4.28.1F Configuration Guide."

Reference: Section 22.1, "MLAG Introduction." This section defines MLAG as a feature that "allows a pair of switches to... form a single, logical LAG," focusing on its role in providing "active-active L2 connectivity" for network resiliency, which is distinct from the monitoring purpose of DANZ.
