Comprehensive and Detailed Explanation:

Whentraffic moves laterally between VMswithin the same network orsubnet, it is known aseast-west traffic. This contrasts withnorth-south traffic, which refers to communication between internal and external networks.

Breakdown of Options:

A. East-west–Correct answer.This refers totraffic between internal servers or VMs, which is a common security concern.

B. Point-to-point– Point-to-point describes adirect connection between two devices, but doesnot specifically define lateral movement.

C. Horizontal-scaling– This refers toadding more instances or nodesin cloud computing, unrelated to traffic flow.

D. Hub-and-spoke– This network topology describes acentralized design, not lateral traffic.

The issue is that no root bridge has been identified. In STP, a root bridge is necessary to manage redundant paths and avoid loops in the network. Without a root bridge, all switches will assume they can forward traffic, causing a network loop and connectivity problems.

=================

Port mirroring, also known as SPAN (Switched Port Analyzer), is used to send a copy of network packets seen on one switch port (or an entire VLAN) to another port where the IDS is connected. This allows the IDS to passively inspect network traffic without interfering with the actual traffic flow. Port mirroring is an essential feature for implementing IDS in a network for traffic analysis and security monitoring.References: CompTIA Network+ study materials.
