Quick reference

ESXi is the bare-metal hypervisor installed on physical servers. A virtual machine (VM) uses virtual CPU, memory, disks, network adapters, and other virtual hardware supplied by an ESXi host. A datastore is a logical storage container for VM files.

vCenter Server centrally manages ESXi hosts and their inventory. It provides the management framework for features such as vMotion, HA, and DRS, but those features also require appropriate ESXi hosts, cluster configuration, licensing, and supporting network and storage infrastructure.

Hosts can be grouped into clusters. A resource pool partitions CPU and memory resources for its child VMs or pools. A VM may be placed directly in a cluster or inside a resource pool. A virtual network consists of virtual switches, port groups, VMkernel adapters, uplinks, and physical NICs.

ESXi administration

• Place an ESXi host into maintenance mode before planned servicing. Running VMs must be powered off or migrated, unless an appropriate automated process handles them.
• Host Profiles capture configuration settings and help apply consistent settings across hosts.
• Check licensing, NTP or other time synchronization, logging, service status, hardware compatibility, alarms, and overall host health.
• Compatible server hardware, firmware, storage adapters, and network adapters reduce installation and operational problems.

Virtual machines and VMware Tools

VMware Tools improves guest integration through drivers and services, including improved network and disk drivers, time synchronization options, clean shutdown support, heartbeat or status information, and guest operations. A template is a master image used for repeatable deployment. A clone is a copy of a VM, while a snapshot records a point-in-time state for short-term rollback.

Storage

VMFS is a VMware clustered file system used with supported block storage such as Fibre Channel, iSCSI, or local devices. An NFS datastore uses a file share exported by an NFS server, normally reached through the network. Storage adapters provide host connectivity to block devices; multipathing supplies alternate paths and can improve availability.

Storage vMotion moves VM files between compatible datastores while the VM remains powered on. Storage DRS uses a datastore cluster to help balance capacity and storage I/O, subject to compatibility and policy constraints.

Networking

A standard vSwitch is configured separately on each host. A vSphere Distributed Switch is centrally managed by vCenter Server and provides consistent switching configuration across multiple hosts. A port group defines connectivity and policies for VMs or VMkernel traffic. A VMkernel adapter carries host services such as management, vMotion, or storage traffic. Uplinks connect the virtual switch to physical NICs and the physical network.

Assign VLAN IDs consistently to the relevant port groups and physical switch ports. Separate management, vMotion, storage, and VM traffic when design and security requirements call for it. NIC teaming and failover policies determine how traffic uses available uplinks and responds to a failed physical NIC or link.

Clusters, availability, and resource management

HA restarts affected VMs on surviving hosts after an ESXi host failure. Admission control reserves enough cluster capacity for the configured failure policy. DRS balances workloads across hosts and can recommend or perform VM migrations when cluster configuration and licensing permit. Fault Tolerance maintains a secondary execution copy for a protected VM, but it has stricter compatibility, resource, networking, and VM configuration limitations than ordinary HA.

Migration comparison

Security, monitoring, and recovery

• A vCenter permission combines a user or group, a role, and an inventory object. A role is a collection of privileges. Permissions can inherit from parent inventory objects, so verify inheritance when limiting access.
• ESXi lockdown mode restricts direct host administration and encourages management through authorized centralized paths. Protect VM consoles, guest credentials, port groups, and management networks.
• Tasks show operations, events record significant changes or conditions, alarms notify administrators, and performance charts help identify CPU, memory, storage, and network contention.
• Use host, VMkernel, vCenter, and storage logs together with status indicators. For a missing datastore, check adapters, zoning or LUN presentation, NFS export access, reachability, rescans, and multipathing.
• A snapshot is useful for a short-term rollback point before a controlled change. It is not a long-term backup. Monitor snapshot age and size, and remove snapshots through supported management operations after they are no longer needed.

Answer review

After completion, select Review Answers to compare your responses with the explanations below.

1. Correct answer: B. vCenter Server manages ESXi inventory and resources. vMotion, HA, and DRS also depend on host compatibility, cluster settings, licensing, and supporting infrastructure.
2. Correct answer: A. Maintenance mode is used before planned servicing so workloads can be migrated or stopped safely.
3. Correct answer: C. VMware Tools supplies guest integration features and drivers that improve management and device behavior.
4. Correct answer: A. Storage vMotion moves VM files between compatible datastores while the VM continues running.
5. Correct answer: A. vMotion uses a VMkernel adapter configured for the vMotion service, along with compatible hosts, storage access, and network connectivity.
6. Correct answer: A. HA restarts affected VMs on surviving hosts. Admission control helps preserve capacity for that recovery.
7. Correct answer: C. Shares establish relative priority during contention. Reservations guarantee minimum capacity, while limits cap consumption.
8. Correct answer: A. EVC masks selected CPU features to make migration possible across hosts with different processor generations within the supported EVC baseline.
9. Correct answer: A. vCenter permissions combine an identity, role, privileges, and an inventory object. Inheritance must be checked to avoid granting excessive access.
10. Correct answer: A. A failed vMotion requires checking VMkernel networking, VLANs, CPU compatibility or EVC, storage visibility, and destination capacity.
