VCP VMware Certified Professional 2V0-21.20 Certification 3 — Questions and Answers
Question 1: What is the minimum number of hosts required to configure a vSAN cluster in vSphere 7?
- 2
- 3 (Correct answer)
- 4
- 6
Correct answer: 3
A standard vSAN cluster requires a minimum of 3 hosts to provide the necessary failure tolerance.
Question 2: In vSphere 7, which component is responsible for authenticating users to vCenter Server?
- VMware Certificate Authority (VMCA)
- Platform Services Controller (PSC)
- vCenter Single Sign-On (SSO) (Correct answer)
- Active Directory Federation Services
Correct answer: vCenter Single Sign-On (SSO)
vCenter Single Sign-On (SSO) is the authentication broker embedded in vCSA 7 that handles identity and token-based authentication.
Question 3: Which vSphere 7 feature automatically restarts VMs on surviving hosts when a host fails in a cluster?
- vSphere DRS
- vSphere HA (Correct answer)
- vSphere Fault Tolerance
- vSphere Replication
Correct answer: vSphere HA
vSphere HA monitors hosts and automatically restarts VMs on surviving cluster hosts when a failure is detected.
Question 4: What is a vSphere 7 Distributed Switch (VDS) uplink port group used for?
- Connecting VMs to the management network
- Connecting physical NICs (pNICs) on hosts to the distributed switch (Correct answer)
- Providing VMkernel port connectivity for vMotion
- Defining traffic shaping policies for VM network adapters
Correct answer: Connecting physical NICs (pNICs) on hosts to the distributed switch
Uplink port groups on a VDS connect physical host NICs to the distributed switch fabric.
Question 5: In vSphere 7, which storage format provides the best random I/O performance for VMs running databases?
- Thin provisioned VMDK
- Thick provisioned lazy-zeroed VMDK
- Thick provisioned eager-zeroed VMDK (Correct answer)
- Raw Device Mapping (RDM) in virtual compatibility mode
Correct answer: Thick provisioned eager-zeroed VMDK
Eager-zeroed thick VMDKs pre-allocate and zero all space at creation, eliminating zeroing overhead during writes and providing best random I/O performance.
Question 6: Which vSphere 7 capability allows administrators to apply consistent network policies across all hosts in a datacenter?
- Standard vSwitch with host profiles
- vSphere Distributed Switch (VDS) (Correct answer)
- NSX-T Data Center
- vSphere Network I/O Control only
Correct answer: vSphere Distributed Switch (VDS)
The vSphere Distributed Switch manages network configuration centrally in vCenter and applies consistent policies to all associated hosts.
Question 7: What is the role of a VMkernel port (vmk) in vSphere 7?
- It provides network connectivity exclusively for virtual machines
- It handles hypervisor-level traffic such as vMotion, management, and storage (Correct answer)
- It connects the physical NIC to the virtual switch uplink
- It provides out-of-band IPMI management access to ESXi
Correct answer: It handles hypervisor-level traffic such as vMotion, management, and storage
VMkernel ports carry ESXi host-level traffic including management, vMotion, vSAN, iSCSI, and NFS, separate from VM traffic.
