VCP vSphere Infrastructure & Networking 1 — Questions and Answers
Question 1: Which vSphere component is responsible for abstracting physical network resources and providing logical switching capabilities for virtual machines?
- vSphere Distributed Switch (VDS) (Correct answer)
- VMkernel adapter
- NSX-T Edge node
- vSphere Standard Switch (VSS)
Correct answer: vSphere Distributed Switch (VDS)
vSphere Distributed Switch (VDS) abstracts physical network resources and provides centralized logical switching across multiple ESXi hosts.
Question 2: What is the default port group created on a vSphere Standard Switch when an ESXi host is first configured?
- Management Network
- VM Network (Correct answer)
- vMotion Network
- Storage Network
Correct answer: VM Network
VM Network is the default port group created on a vSphere Standard Switch during initial ESXi host configuration.
Question 3: Which feature in vSphere allows live migration of virtual machines between ESXi hosts without any downtime?
- Storage vMotion
- vMotion (Correct answer)
- High Availability (HA)
- Fault Tolerance (FT)
Correct answer: vMotion
vMotion enables live migration of powered-on virtual machines between ESXi hosts with zero downtime by transferring VM memory and state.
Question 4: In vSphere networking, what is the purpose of a VMkernel (vmk) adapter?
- To connect virtual machines to physical networks
- To handle host-level traffic such as vMotion, management, and storage (Correct answer)
- To provide VLAN tagging for guest VMs
- To load-balance traffic across physical NICs
Correct answer: To handle host-level traffic such as vMotion, management, and storage
VMkernel adapters handle ESXi host-level traffic including management, vMotion, vSAN, and iSCSI/NFS storage communications.
Question 5: Which NIC teaming policy in vSphere uses the virtual machine's port ID to determine which physical uplink to use?
- Route based on IP hash
- Route based on originating virtual port (Correct answer)
- Route based on source MAC hash
- Explicit failover order
Correct answer: Route based on originating virtual port
Route based on originating virtual port assigns each VM port to a specific uplink using the port ID, providing simple load distribution.
Question 6: What is the maximum number of physical NICs (uplinks) that can be added to a single vSphere Distributed Switch?
- 8
- 16
- 32 (Correct answer)
- 64
Correct answer: 32
A vSphere Distributed Switch supports up to 32 physical NIC uplinks per host, providing extensive bandwidth and redundancy options.
