An All-Flash vSAN cluster has 4 nodes with this disk group composition on each host:
1 × 800 GB SAS SSD
6 × 3.84 TB SATA SSD
An administrator observes that in an All-Flash cluster, the Write Buffer Free Percentage is consistently low. As a result, there is increased latency experienced by the workloads.
Which remediation steps will resolve this issue?
A. Add a second disk group with a new cache device and distribute the capacity disks equally.
B. Add a second cache device to the same disk group to increase the caching size.
C. Modify advanced vSAN configuration parameters to utilize the complete 800 GB for caching.
D. Replace the existing cache device with a larger cache device.
Which is true of the vSAN iSCSI target service?
A. It is a VMware supported cost effective way to provide shared storage to another hypervisor.
B. The vSAN default storage policy determines the characteristics of the vSAN iSCSI target service storage objects.
C. Security is provided through the iSCSI CHAP and Mutual CHAP Authentication methods.
D. It is a VMware supported solution to provide iSCSI targets to applications that require multiple connections per session (MCS).
An infrastructure architect is designing a vSAN Cluster that must satisfy these requirements:
support storage policies with 2 failures ?RAID-1 (Mirroring)
support storage policies with 2 failures ?RAID-6 (Erasure Coding)
virtual machines must maintain compliance with the storage policy rules above when one host is in maintenance mode with full data migration
What is the minimum number of hosts needed to achieve these design requirements?
A. 6
B. 8
C. 5
D. 7
A higher level of resiliency has been requested for an existing vSAN Stretched Cluster. A key requirement will be the addition of a third site to protect against a potential double site failure of the two mirrored sites in the stretched cluster. What solution would meet the resiliency requirement?
A. Replicate to the third site at the VM level using vSphere Replication.
B. Configure vSAN Stretched Cluster with FTT=2 to replicate to the third site.
C. Add the third site to the existing vSAN Stretched Cluster.
D. Replicate to the third site at the vSAN datastore level using Site Recovery Manager.
An architect is designing network high availability for a new vSAN Cluster. Which is a supported configuration for this design?
A. Use LACP on the distributed switch with a route based on IP hash algorithm.
B. Create multiple VMkernel adapters on the same subnet for vSAN.
C. Configure multicast to use two separate network interfaces for vSAN traffic.
D. Create an additional TCP/IP stack within the cluster and specify vSAN type.
Which three should be taken into consideration when configuring a Stretched Cluster? (Choose three.)
A. bandwidth between sites
B. geographical distance
C. number of objects
D. vSphere version
E. latency between sites
An administrator is tasked with expanding an existing 2-node vSAN cluster at a remote site to meet the increasing storage capacity requirement by 30%. The existing cache is underutilized. Which solution provides the best configuration that maximizes existing ROI?
A. Scale out two more nodes.
B. Add capacity drives to existing disk groups.
C. Scale out one more node.
D. Replace all cache and capacity with larger drives.
An administrator has been tasked with the shutdown process of one of the nodes in a 4-node vSAN Cluster, in order to replace a motherboard. The administrator must select the correct maintenance mode option to ensure all objects remain compliant with the vSAN Default Storage Policy. No changes have been made to this policy.
Which maintenance mode option should the administrator select?
A. Allow Reduced Redundancy
B. Ensure Accessibility
C. Full Data Migration
D. No Data Migration
An administrator is working with an application which has three characteristics:
latency sensitive database striped over multiple virtual disks no application redundancy
Which storage policies meet the VM performance and cluster constraint while protecting against at least 1 failure?
A. RAID 6, Stripe Width 2
B. RAID 1, Stripe Width 2
C. RAID 1, Stripe Width 1
D. RAID 5, Stripe Width 1
Which Kubernetes component must be configured to allow for dynamics provisioning of container volumes on vSAN?
A. vSphere Container Storage Interface driver
B. vSphere Cloud Storage Plugin
C. glusterfs
D. Cinder
