Exam CISA topic 1 question 166 discussion

Must be B

Correct answer is B. CISA review manual 27th Edition states, "Although virtualization offers significant advantages, they bring risk that an enterprise must manage effectively. Because the host in a virtualized environment represents a potential single point of failure within the system, a successful attack on the host could result in a compromise that is larger in both scope and impact."

D. Performance issues of the host. This is because virtual systems are highly dependent on how well the host system is performaning. Any system failure with the host, would automatically have a ripple effect on all the virtual systems depending on it.

In CRM Figure 5,30 Mention both B and D as disadvantages. Is very hard to choose one over the other, CISA is doing it again with these confusing questions.. I would say biggest risk is the Single Point of Failure, over the performance

D. As per CISA review manual. "Performance issues of the host’s own OS could impact each of the host’s guests."

The most significant risk associated with the use of virtualization is a single point of failure. Virtualization involves consolidating multiple virtual machines (VMs) onto a single physical server or host. If the host experiences a failure or outage, it can potentially impact multiple VMs running on that host, leading to a significant disruption of services.

The most significant risk associated with the use of virtualization is the single point of failure. In a virtualized environment, multiple virtual machines (VMs) run on a single physical host. If that host fails, all the VMs running on it will also fail, causing a significant impact on the availability of services and applications.

B should be the correct answer, since virtualizing a server means having one single point of failure which is the server itself, all the other guests depend on this server

i think B bcos C and D also finally affect the inadequate configuration of host/ performance issues of host will bring the host down.. which is nothing but single point of failure of the host itself.

Per CISA manual: Although virtualization offers significant advantages, they bring risk that an enterprise must manage effectively. Because the host in a virtualized environment represents a potential single point of failure within the system, a successful attack on the host could result in a compromise that is larger in both scope and impact. Ans = B!
