Question 1
- An enterprise architect is designing the physical networking architecture for a greenfield VMware CloudFoundation (VCF) deployment in a single data center. The deployment includes a management domain andmultiple workload domains, utilizing NSX for software-defined networking with Geneve overlayencapsulation. NSX Edge nodes will handle North/South routing and services.Requirements:Scalable, non-blocking fabric with predictable oversubscription and low latency.Support for high-throughput traffic including vSAN, vMotion, and NSX overlay.End-to-end jumbo frame support for efficiency.No dependency on physical multicast routing or snooping for overlay (BUM) Broadcast, Unknownunicast, and Multicast replication.Redundant connectivity from hosts to the fabric.Constraints:Existing Top-of-rack switches are limited to 25 GbE host-facing ports.The physical network does not support multicast.Future expansion to multiple racks and higher port speeds (25/100 GbE) is anticipated.What are the four design decisions that fit the architecture ' s physical design? (Choose four.)
  A : Enable jumbo frames MTU 9190 end-to-end across all switch ports, inter-switch links, and VLAN Layer 3 interfaces used for host transport traffic.
  
  B : Configure head-end replication mode for BUM traffic in the NSX overlay transport zone to eliminate multicast dependency.
  
  C : Each ESX host has at least two 25 GbE physical NICs, connected redundantly to separate leaf (ToR) switches.
  
  D : Use multicast replication mode in the NSX overlay transport zone to leverage physical network multicast for BUM traffic.
  
  E : Each ESX host with at least two 10 GbE physical NICs, connected redundantly to separate leaf (ToR) switches.
  
  F : Deploy a leaf-spine topology with Layer 3 routing BGP between leaf and spine layers for scalable ECMP routing.
  
  G : Implement Layer 2 extended across aggregation switches for VLAN spanning.
  
  Answer: A,B,C,F
Question 2
- An architect is planning an installation of VMware Cloud Foundation (VCF) Automation which was notdeployed during the initial VCF deployment. Currently, the management cluster is based on three ESX hostsand reports CPU contention which is not recommended for VCF Automation. There are already 10 workloaddomains with dedicated NSX instances deployed in this VCF instance.To mitigate VCF Automation performance issues, which two design decisions will meet the requirements?(Choose two.)
  A : Disable the balloon driver for NSX Manager appliances.
  
  B : Remove reservations for VCF Automation appliances.
  
  C : Add additional ESX servers to satisfy the additional compute requirements.
  
  D : Ensure 1:1 ratio between pCPU and vCPU.
  
  E : Set NUMA placement to manual.
  
  Answer: C,D
Question 3
- A customer is planning to implement a VMware Cloud Foundation (VCF) environment to support a mix ofproduction and development virtualized workloads. The customer intends to use vSAN as the principalstorage solution for both environments. During the initial planning meeting, the following requirements wereidentified:The production environment requires high availability and fault tolerance, with at least 1 copy of eachVM ' s data.The development environment needs to be able to tolerate availability, with 2 copies of each VM ' sdata.The customer is planning to deploy 15 ESX hosts in the cluster.The customer expects to onboard 475 virtual machines in the production environment and 250 VMs inthe development environment, with an average disk size of 275 GB per VM.The customer requires storage policies that provide redundancy and high performance in thedevelopment environment but can afford lower redundancy and performance in the productionenvironment.Given these requirements, which two factors will impact the storage design for this VCF implementation?(Choose two.)
  A : Number of physical host NICs allocated to ESX management traffic
  
  B : Network bandwidth for workload traffic
  
  C : Type of storage policies used in vSAN (e.g., FTT, stripe width)
  
  D : Number of virtual machines and their resource allocation
  
  E : Total number of ESX hosts in the cluster
  
  Answer: C,D
Question 4
- An architect is designing a VMware Cloud Foundation (VCF) single sign-on solution with the followingrequirements:The provider should be able to handle failure of a single node.Some VCF components will not be able to access the management domain vCenter.The solution should be deployed using the fewest nodes possible, while still addressing all otherrequirements.Which deployment mode for the single sign-on provider should be used?
  A : VCF LDAP Services (Embedded Mode)
  
  B : VCF Identity Broker (Embedded Mode)
  
  C : VCF LDAP Services (Appliance Mode)
  
  D : VCF Identity Broker (Appliance Mode)
  
  Answer: D
Question 5
- An architect is designing a VMware Cloud Foundation (VCF) deployment for a customer transitioning to ahybrid cloud environment. The customer has provided the following requirements:Networking Capacity: The existing data center infrastructure includes 10 GbE switches and NICs, butthe customer plans to upgrade to 25 GbE within the next 12 months to support higher throughput formanagement traffic, overlays, and future workload domains.Storage: The Management Domain must provide at least 15 TB of usable storage initially, with 20–30% headroom for organic growth in management components over the next 2 years. The customerprefers an all-flash configuration for performance.Growth: The deployment will start with the Management Domain and expand to include up to 2additional Workload Domains within 18 months, requiring scalability in compute and storage withoutmajor redesign.Based on the customer ' s requirements and VMware Cloud Foundation design guidelines, identify the keydesign decisions for the physical design of the VCF Management Domain.Which three actions support the requirements for hosts, networking, storage, and growth? (Choose three.)
  A : Allow heterogeneous host configurations to leverage existing hardware inventory, as long as overall cluster capacity meets minimum thresholds.
  
  B : Equip each ESX host with dual 10 GbE NICs initially, ensuring support for Jumbo Frames (MTU 9000) and planning for a non-disruptive upgrade to 25 GbE NICs to align with future bandwidth needs.
  
  C : Implement vSAN ESA with an all-flash configuration, providing a minimum of 20 TB raw capacity across the cluster accounting for FTT=1, 30% vSAN overhead, and 20% growth reserve.
  
  D : Configure each ESX host with at least 22 physical CPU cores and 512 GB of RAM to accommodate the base management components plus resources for managing additional Workload Domains.
  
  E : Deploy a minimum of 3 ESX hosts in the Management Domain to optimize initial hardware costs while maintaining basic redundancy.
  
  F : Implement vSAN OSA with a hybrid configuration, providing a minimum of 20 TB raw capacity across the cluster accounting for FTT=1, 30% vSAN overhead, and 20% growth reserve, using at least 2 disk groups per host for performance and fault tolerance.
