Answer : A

Strict Lockdown Mode is the correct choice because it restricts all access to the ESXi host directly, ensuring that configuration can only be performed through VMware vCenter. This is in line with the requirement that configuration can only be done via vCenter.

Strict Lockdown Mode disables the Direct Console User Interface (DCUI) and SSH services, which aligns with the customer's requirement to have these services disabled for security purposes.

Answer : B, C

Enable vSphere with Tanzu on a cluster deployed at a remote location.

VMware Cloud Foundation remote clusters can be deployed to extend the functionality of vSphere with Tanzu to remote locations. This allows for containerized workloads to be managed and orchestrated using the same tools as the primary environment, providing consistent management of Tanzu clusters across multiple sites.

Provide resources for virtual machines at an edge location.

Remote clusters can be deployed at edge locations to provide computing resources for workloads that need to run close to the data source. This use case is particularly useful for applications that require low latency or need to process data locally before sending it to the central cloud infrastructure.

Answer : D

Network I/O Control (NIOC) is a key feature available with distributed virtual switches (vDS) that allows administrators to prioritize and allocate bandwidth to specific network traffic types. It ensures that business-critical applications receive the necessary bandwidth and maintain a consistent quality of service (QoS). This solution meets the requirement to ensure optimal network bandwidth allocation and service consistency.

Answer : B

NUMA (Non-Uniform Memory Access) is a system architecture in which a multiprocessor system is divided into multiple memory nodes. Each NUMA node typically has its own local memory that is faster to access than remote memory from other nodes.

In this case, each ESXi host has two CPU sockets (each with 20 cores) and 1024 GB of RAM divided evenly between the two sockets, meaning there are two NUMA nodes in each host.

By limiting the virtual machine to a maximum of 20 cores and sockets per virtual machine, and 512 GB of RAM, this ensures that each virtual machine will fit within a single NUMA node, preventing the virtual machine from crossing NUMA node boundaries. This design helps maintain better memory access performance and avoids potential performance degradation that can occur when a VM accesses memory across NUMA nodes.

Answer : D

Given that VMware Tools 11 or higher is installed on all virtual machines and VMware PowerCLI is available in the environment, the architect can leverage PowerCLI to interact with VMware Tools and collect information about active services running inside the virtual machines.

VMware PowerCLI allows you to query virtual machines for information about their services by accessing the guest operating system, provided VMware Tools is installed and running. You can use PowerCLI cmdlets to retrieve service data, such as which services are running on the VM, their statuses, and other details necessary for planning the migration.

This option is cost-effective since there is no budget available for additional discovery tooling, and it aligns well with the existing tools and infrastructure already in place.
