EMC Proven Professional – Technology Architect — Question 9

In a cloud infrastructure, the computer systems of multiple consumers share the same network infrastructure. The cloud provider wants to restrict the communication among consumers computer systems by enabling isolation over the shared network infrastructure.
Which mechanism enables this isolation?

Answer options

Correct answer: A

Explanation

A Virtual LAN (VLAN) effectively segments network traffic, ensuring that different consumers' systems cannot directly communicate, thus providing isolation. A firewall controls access but does not inherently provide network-level isolation for multiple users on a shared infrastructure. An intrusion prevention and detection system focuses on monitoring and protecting against threats rather than isolating traffic. The iSNS discovery domain is related to storage networks and doesn't serve the purpose of isolating consumer systems in a shared network.
