Exam 3V0-21.21 topic 1 question 8 discussion

Is A and C 100% for sure, i did the course of vSphere Desing 7 and this example is in the page 31 of the book.

I'd say it is A and E: A. Manageability (Scalability) B. Avalability C. Security D. Security E. Manageability (Scalability)

Manageability = Managing the infrastructure in terms of lifecycle management, scalability, and capacity planning B is an availability non-functional requirement. D is a security NFR and E is a scalability NFR

A and C, it's in the book page 31.

correct answer should be ACE: A&E is Manageability (Scalability/Capacity planing), C is Manageability (lifecycle management)

The Answer AC

Manageability: Description Managing the infrastructure in terms of lifecycle management, scalability, and capacity planning. Measurements (Often in SLAs) Examples Cluster nodes must scale when compute resources are sustained at 70%+ for 5 business days. ESXi host updates must be installed within 1 week of release.

Examples of Nonfunctional Requirements: Quality: Manageability Description: Managing the infrastructure in terms of lifecycle management, scalability, and capacity planning Measurements (Often in SLAs): Cluster nodes must scale when compute resources are sustained at 70%+ for 5 business days. ESXi host updates must be installed within 1 week of release.

Answer A & C are Manageability, Non Functional Requirements.

https://enkonix.com/blog/functional-requirements-vs-non-functional/ "Functional requirements explain how the system must work, while non functional requirements explain how the system should perform" A and C.

Lecture book page 31 section 2-26 Examples of Nonfunctional Requirements

C-- as it could be related to Manageability . E- ESXi clusters must scale to 500 concurrent virtual machines -- it is like a requirement, while option A is a condition of if the utilization stays above 70% then the cluster should scale. A may or may not happen , but E needs to be satisfied.

I'd Say A and C vSphere Desing 7 2-26 Examples of Nonfunctional Requirements Manageability Managing the infrastructure in terms of lifecycle management, scalability, and capacity planning Cluster nodes must scale when compute resources are sustained at 70%+ for 5 business days. ESXi host updates must be installed within 1 week of release.

@JLF_VMW is correct, this is in the vSphere Design book and states under non-functional manageability : "Cluster nodes must scale when compute resources are sustained at 70%+ for 5 business days. ESXi host updates must be installed within 1 week of release."

I am in doubt here, it could be A & E or A & C A for sure is correct - Manageability (Scalability) B is availability D is security C could be considered both manageability and security. D it seems to me only scalability, but not manageability. I would say A and C in the end. But not 100% sure anyway.

Probably A & E A. ESXi clusters must scale when compute resources are sustained above 70% for five business days - Scalability/Manageability B. vSphere Fault Tolerance must be supported to improve application uptime - Availability C. ESXi host updates must be installed within one week of release - Security D. The vSphere environment must support administrator password rotation - Security E. ESXi clusters must scale to 500 concurrent virtual machines - Scalability/Manageability
