Question

A vulnerability was recently announced that allows a malicious user to gain root privileges on other virtual machines running within the same hardware cluster.

Customers of which of the following cloud-based solutions should be MOST concerned about this vulnerability?

A. Single-tenant private cloud
B. Multitenant SaaS cloud
C. Single-tenant hybrid cloud
D. Multitenant IaaS cloud
E. Multitenant PaaS cloud
F. Single-tenant public cloud

Answer 1

The customers of the Multi-tenant IaaS cloud should be the most concerned about this vulnerability.

Step-by-step explanation:

The customers of the Multi-tenant IaaS cloud should be the most concerned about this vulnerability. In a multi-tenant infrastructure-as-a-service (IaaS) cloud, multiple users or organizations share the same physical hardware infrastructure. Since the vulnerability allows a malicious user to gain root privileges on other virtual machines within the same hardware cluster, it poses a significant threat to the security and isolation of the virtual machines in the multi-tenant IaaS cloud.

On the other hand, in a single-tenant private cloud or single-tenant hybrid cloud, the physical hardware infrastructure is dedicated to a single customer or organization. This means that the vulnerability would not affect other virtual machines running within the same hardware cluster as they belong to the same customer.

Therefore, the customers of the multi-tenant IaaS cloud should be the most concerned about this vulnerability.
