A customer wants to virtualize an Oracle database with vSphere 6.5, but is concerned about its performance.
Which three design elements will ensure optimum performance? (Choose three.)
To ensure optimum performance when virtualizing an Oracle database with vSphere 6.5: 1) Use VMXNET3 for the network adapter as it provides better performance and higher throughput. 2) Use VMware Paravirtual SCSI adapters for data and log vDisk as they are optimized for high-performance I/O operations. 3) Enable Hyper-Threading because it allows more efficient usage of CPU resources, improving overall performance.
A development team must provide layer 2 network isolation between virtual machines that are in the same VLAN. The solutions architect must provide additional security between the virtual machines on the same subnet.
How can this be done without consuming more VLANs?
Private VLANs (PVLANs) allow for enabling layer 2 network isolation between virtual machines within the same VLAN. This creates a private communication domain and adds an additional layer of security between virtual machines on the same subnet without the need to consume more VLANs.
DRAG DROP -
A company is outsourcing its support operations to an external service provide and plans to complete the project by April 1.
✑ The external support engineers must have the ability to power cycle, create, and edit virtual machines settings within their assigned vSphere site.
✑ The company maintains three vCenter servers in Enhanced Linked Mode that are run as virtual machines in the supported infrastructure.
✑ The vCenter servers will be supported by the external service provider.
✑ Each vCenter server is connected to its own local Platform Services Controller and MSSQL database server.
✑ The company will provide escalation support and physical access on a per request basis.
✑ 99.9% ESXi host uptime is required in this environment, but no SLA has been specified for the hosted applications.

A customer has requested a vSphere 6.5 deployment design that utilizes vCenter Server and the use of VMware-recommended best practices for securing vCenter Server.
Which three actions would satisfy these requirements? (Choose three.)
To ensure the security of vCenter Server as recommended by VMware best practices, the following actions should be taken: Restricting vCenter Server access to only the management network helps to limit exposure and unauthorized access. Synchronizing the time in the vCenter Server with a trusted NTP source ensures accurate timekeeping, which is crucial for security protocols dependent on timestamps. Removing expired and revoked certificates from the vCenter Server system prevents the use of potentially compromised or outdated security credentials. Utilizing vSphere CLI and vSphere SDK for Perl scripts, while useful, is not primarily a security measure. Assigning the default Administrator role to all administrator users is discouraged as it does not adhere to the principle of least privilege.
A database administrator is operating a virtual machine (VM) configured with 16 vCPU and 64GB of RAM. A recent performance audit has indicated that this virtual machine is oversized and is using less than 60% of its configured CPU and memory capacity.
✑ The ESXi host that contains this VM has 2 physical processors with 10 cores per processor, and 128GB of RAM.
✑ This physical host's architecture is split into two equal NUMA nodes.
Which vCPU and RAM configuration for the VM allows for the most resources, but also provides the performance benefit of local NUMA access?
In this scenario, the virtual machine is currently over-provisioned with 16 vCPUs and 64GB of RAM and is utilizing less than 60% of these resources. With the ESXi host having 2 physical processors with 10 cores each, split into two NUMA nodes, the goal is to right-size the VM to improve performance by ensuring local NUMA access. Reducing to 10 vCPUs ensures that all vCPUs can fit within a single NUMA node (which has 10 cores). Keeping the RAM at 64GB avoids cross-node memory access, optimizing performance as the physical memory of one NUMA node is utilized. Therefore, configuring the VM with 10 vCPU and 64GB RAM is the best choice to leverage the NUMA architecture effectively while providing sufficient resources.
