Exam 3V0-21.21 topic 1 question 79 discussion

A. There will be an increase in management overhead. E. There will be additional licensing and cost requirements for both clusters. A. There will be an increase in management overhead. - multiple clusters to manage B. Identical hardware must be procured for all hosts. - seperate clusters so hardware can be very different C. There will be a reduction in performance. - there would be a performance increase in segregation D. The patching cycles will affect both clusters at the same time. - this is not true. E. There will be additional licensing and cost requirements for both clusters. - process of elimination leaves this

Correct Answer : A, E

Anwsers A&E are correct. A >> Yes. More clusters, more things to manage, so more overhead B >> No. The hardware can be different, and even better adapted regarding the needs of each type of workload C >> No. It may have an impact, if we started from an existing cluster, and we split it into 2 parts. But nothing says here it is the case. D >> No. It is even the opposite, they can me be managed separately E >> Yes. With 2 clusters instead of 1, we may need additional hosts, and then additional licences. We may also have impacts on guest OS licences, or vSAN licences if we use it.

Answer : A, E

Moving from 1 cluster to 2 clusters will have an impact on the number of required ESXi host per cluster (N+1), therefore generating additional costs for both hardware and ESXi licenses. So A & E to my opinion

A - more clusters to manage E - VDI and APPs cluster can have different requirements resulting in different cost and licensing models.

Thinking about this a bit longer... A is obvious, we don't need to talk about - CORRECT B No, simply no - FALSE C No, cluster size does not impact VM performance - FALSE E is difficult. And FALSE. If you think of Horizon for a second: It already includes vSphere Desktop. So if you split the cluster, you'll need vSphere Standard licenses for the cluster hosting the application servers. On the other hand you weren't allowed to operate the application servers on a vSphere Desktop licensed single cluster. Thinking further gives the clue that you split an existing cluster: So the vSphere Standard licenses must already be there, also a vCenter. You don't need additional licenses then - given the fact that both clusters are managed by the same vCenter. But now...Horizon is dependent on vCenter Server. So if you update... D The patching will AFFECT both clusters at the same time - CORRECT So it's A and D.

A and E Why should you have to patch both clusters at the same time? Why should the host hardware be identical? Why would separation into clusters mean a reduction in Performance?

A. There will be an increase in management overhead. - CORRECT: multiple clusters to manage B. Identical hardware must be procured for all hosts. - NO: seperate clusters so hardware can be different C. There will be a reduction in performance. - CORRECT: single cluster with (example) 10 ESXi splitted in 2 Clusters with 7 and 3 ESXi cannot be better in performance. D. The patching cycles will affect both clusters at the same time. - NO: this is not true. E. There will be additional licensing and cost requirements for both clusters. - NO: why? is not needed additional license for number of clusters, only for number of ESXi (CPU) and\or vCenter Instances.

A and E will be the correct answers. See answer nemisis95

everyone agrees with A but why discard E? Horizon have different type of licensing than vsphere. Horizon delivery ESXi and vCenter, so in an environment when you mix desktop and server you can work (not recommended) But if you separate, you need vsphere for the other cluster

A & E ?

My thoughts about about this question. Firs of all, it is terribly written... It is not clear to me if they are reusing the existing environment or if they consider the option of adding new hosts. In any case A is correct. Now C or E? 1) In case of reusing the existing cluster and separate it into 2 clusters >> C. There will be a reduction in performance 2) In case of adding new hosts >> E. There will be additional licensing and cost requirements for both clusters. D and C are out of the question.

My guess: A and D.

I thnik A & C
