Which techniques help manage storage performance when multiple VMs compete for I/O on the same datastore?
- A . Storage I/O Control (SIOC) to throttle high I/O workloads
- B . Applying Resource Pools to storage for CPU/memory performance
- C . Using vVols to enable array-based storage QoS
- D . Thin provisioning to reduce physical disk usage
A, C
Explanation:
SIOC (A) and vVols (C) can limit or manage I/O across VMs. Resource Pools (B) govern CPU/memory, not storage. Thin provisioning (D) saves capacity but doesn’t directly control performance.
An administrator has been tasked with deploying a new VMware Cloud Foundation (VCF) environment and is preparing the physical hosts that will be used for the management domain.
The administrator has completed the following tasks for all of the physical hosts:
– The required version of ESXi has been installed.
– Networking has been configured for the ESXi management interface.
– DNS entries have been created for forward and reverse name resolution.
– NTP has been configured and the time synchronized with a centralized time source.
– VLAN 10 has been presented to the ESXi hosts on the physical network infrastructure for the VCF ESXi management network.
A combination of which two additional tasks must the administrator complete before starting the bring-up of the management domain? (Choose two.)
- A . Upload the Cloud Builder appliance OVA file to the new shared NFS datastore.
- B . Create a new vSphere Standard Switch for the VCF ESXi management network on each ESXi host.
- C . Configure a new shared NFS datastore on each ESXi host.
- D . Replace the SSL certificate with either a CA signed or self-signed certificate on each ESXi host.
- E . Configure VLAN 10 on the VM network Port Group of the vSphere Standard Switch on each ESXi host.
In vSphere networking, which feature ensures network consistency and centralized management across multiple ESXi hosts?
- A . Standard vSwitch (vSS)
- B . Network I/O Control (NIOC)
- C . Distributed vSwitch (vDS)
- D . Port Mirroring
C
Explanation:
A vDS spans multiple hosts and centralizes network configuration and management, ensuring consistent port groups, policies, and VLANs across the cluster. vSS is host-specific, NIOC is a traffic-management feature on vDS, and port mirroring is for network traffic troubleshooting.
What is the primary purpose of configuring VM storage policies in a VMware vSphere environment?
- A . To manage network traffic between VMs.
- B . To enforce specific storage requirements such as performance, availability, and redundancy.
- C . To configure CPU and memory reservations for VMs.
- D . To automate the backup of virtual machines.
B
Explanation:
The primary purpose of configuring VM storage policies in a VMware vSphere environment is to enforce specific storage requirements such as performance, availability, and redundancy. These policies help ensure that virtual machines are placed on datastores that meet the desired service levels and characteristics.
An organization has 3 data center sites and is implementing a solution to achieve a Recovery Point Objective (RPO) of 0 to ensure continuous availability of storage in the event of a single site failure. The sites are connected via a high bandwidth/low latency link.
Which two VMware Cloud Foundation (VCF) components can be used to support this capability? (Choose two.)
- A . vSphere
- B . Aria Operations
- C . NSX
- D . vSphere Replication
- E . vSAN
A, E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To achieve an RPO of 0 (zero data loss) with continuous availability of storage across multiple sites,
VMware Cloud Foundation leverages two key components:
vSphere (A): vSphere provides the core platform for compute virtualization, including features such as VMware vSphere HA (High Availability) and VMware vSphere Fault Tolerance, both of which are integral to delivering continuous VM availability and supporting cross-site failover.
vSAN (E): vSAN can be configured in a stretched cluster deployment across the three sites. With a stretched vSAN cluster, data is synchronously replicated between sites, ensuring that all writes are committed to more than one location. This synchronous replication provides true continuous availability and a Recovery Point Objective (RPO) of 0 in the event of a single site failure, provided that the network meets high bandwidth and low latency requirements.
Other components such as Aria Operations and NSX do not provide storage-level availability or synchronous data protection. vSphere Replication only supports asynchronous replication and cannot guarantee RPO of 0.
Which vSphere feature allows you to replicate a powered-on VM’s data to another site, providing a foundation for DR?
- A . Fault Tolerance (FT)
- B . vSphere Replication
- C . Storage DRS
- D . vSphere Pod Storage
B
Explanation:
vSphere Replication copies VM data to a remote site for disaster recovery scenarios. FT maintains a live secondary VM on another host (but in the same site typically), and Storage DRS balances storage resources. “vSphere Pod Storage” is not a standard vSphere feature.
While deploying a new VMware Cloud Foundation environment, a cloud administrator validates the information entered into the Deployment Parameter Workbook. The validation action results in an error and the VMware Cloud Builder GUI error message does not identify the cause.
Which logfile can the administrator use to identify the cause of the validation error?
- A . VMware SDDC Manager appliance – vcf-deployment-debug.log
- B . VMware Cloud Builder appliance – vcf-bringup-debug.log
- C . VMware SDDC Manager appliance – vcf-bringup-debug.log
- D . VMware Cloud Builder appliance – vcf-deployment-debug.log
D
Explanation:
The vcf-deployment-debug.log file on the VMware Cloud Builder appliance contains detailed logs related to the deployment process, including any validation errors. This log will help identify the cause of the error during the deployment validation phase.
When configuring a new port group on a Virtual Distributed Switch (VDS), what is the purpose of setting a VLAN ID?
- A . To manage storage replication settings
- B . To segment and isolate network traffic.
- C . To automate the creation of VMs within the port group.
- D . To enable load balancing across multiple uplinks.
B
Explanation:
Setting a VLAN ID on a port group on a Virtual Distributed Switch (VDS) allows for network segmentation by tagging traffic with the appropriate VLAN ID. This enables isolation of network traffic between different VLANs, ensuring that communication is restricted to specific segments of the network as required.
What is the primary purpose of configuring a Virtual Distributed Switch (VDS) in a vSphere environment?
- A . To automate the deployment of virtual machines.
- B . To provide centralized management of network configurations across multiple ESXi hosts.
- C . To manage storage policies for datastores.
- D . To enable VM snapshots across multiple datastores.
B
Explanation:
A Virtual Distributed Switch (VDS) in a vSphere environment enables centralized management of network configurations across multiple ESXi hosts. It simplifies network administration by allowing the administrator to configure network settings, such as VLANs, port groups, and policies, for multiple hosts at once, ensuring consistency and scalability.
An administrator is preparing to deploy VMware Aria Suite Lifecycle using SDDC Manager.
Which three are prerequisites for deploying Aria Suite Lifecycle? (Choose three.)
- A . Ensure that a custom SSL certificate specifying the FQDN of the appliance is available.
- B . Ensure that the NTP and DNS settings specified in SDDC Manager are valid for all management components.
- C . Verify that the password for the admin(g>local user account meets the complexity requirements.
- D . Ensure that the Application Virtual Networks have been configured.
- E . Ensure the VMware Software Install Bundle for VMware Aria Suite Lifecycle is in the local bundle repository.
A, B, E
Explanation:
Ensure that a custom SSL certificate specifying the FQDN of the appliance is available: A custom SSL certificate for the FQDN of the Aria Suite Lifecycle appliance is required for secure communication between components.
Ensure that the NTP and DNS settings specified in SDDC Manager are valid for all management components: Accurate NTP and DNS settings are crucial for time synchronization and proper domain resolution in the environment.
Ensure the VMware Software Install Bundle for VMware Aria Suite Lifecycle is in the local bundle repository: The required software bundle must be available in the local repository to ensure successful deployment.
