NEW QUESTION # 55
An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.
The development cluster host configuration is:
4 ESXi hosts with 2 sockets × 16 cores
512 GB RAM divided evenly between sockets
There is no resource contention
The benchmarking cluster host configuration is:
8 ESXi hosts with 2 sockets × 8 cores
256 GB RAM divided evenly between sockets
There is no resource contention
The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster. Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.
What is a possible reason for the difference in performance test results between the development and benchmarking clusters?
- A. The database tier breaches a single NUMA node boundary for the development cluster
- B. The development cluster can support a lower %Ready time per vCPU
- C. The database tier breaches a single NUMA node boundary for the benchmarking cluster
- D. The development cluster has more available RAM per host

NEW QUESTION # 61
An architect is finalizing the design for a new vCenter Server High Availability deployment.
What is one thing the architect must document in the design?
- A. The vCenter Management Network IPv4 addresses for the witness node vCenter Server
- B. The SSH configuration settings for the vCenter Server's active node
- C. The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)
- D. The details of each of the vCenter Server licenses for active, passive and witness nodes
Answer: B
Explanation:
vCenter HA uses SSH keys for password-less authentication between the Active, Passive, and Witness nodes. The authentication is used for heartbeat exchange and file and data replication. To replace the SSH keys in the nodes of a vCenter HA cluster, you deactivate the cluster, generate new SSH keys on the Active node, transfer the keys to the passive node, and activate the cluster.

NEW QUESTION # 64
An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?
- A. Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.
- B. Run both resource profiles on the same cluster with the same host hardware platform.
- C. Separate the two resource profiles into two clusters. The Tier 2 cluster will have faster CPU and more memory while the Tier 1 cluster will have slower CPU and less memory but more disk space.
- D. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.

NEW QUESTION # 67
An architect is reviewing a physical storage design. The customer has specified that a new active-passive based storage array will be used to provide storage for the vSphere clusters.
Which configuration should for the architect recommended?
- A. VMW_SATP_DEFAULT_AA
- B. VMW_SATP_LOCAL
- C. VMW_PSP_MRU
- D. VMW_PSP_FIXED
Answer: C
Explanation:
The Most Recently Used (VMware) policy is enforced by VMW_PSP_MRU. It selects the first working path discovered at system boot time. The Most Recently Used policy does not use the preferred path setting. This policy is default for most active-passive storage devices. https://docs.vmware.com/en/VMware-vSphere/6.7/vsphere-esxi-vcenter-server-671-storage-guide.pdf
