NEW QUESTION # 41
An administrator is troubleshooting a vSAN performance issue. In the vSAN performance monitor there is a high latency on the vSAN cluster.
What is a possible cause of this?
Answer: A
Explanation:
Explanation
A possible cause of high latency on the vSAN cluster is that there is congestion in one or more disk groups.
Congestion is a measure of how busy the storage devices are in handling I/O requests. When congestion is high, it means that the storage devices are overloaded and cannot process the requests fast enough, resulting in increased latency and reduced throughput. Congestion can be caused by various factors, such as insufficient cache capacity, disk failures, network issues, or heavy workload. The other options are not likely to cause high latency on the vSAN cluster. The Virtual Machines can use PVSCSI controllers without affecting latency, as they are optimized for high performance. Erasure Coding is a space efficiency feature that does not impact latency significantly. Jumbo frames are not required for vSAN, and enabling them does not guarantee lower latency.

NEW QUESTION # 42
During yesterday's business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?
Answer: B
Explanation:
Explanation
To replace a failed cache drive in a vSAN OSA cluster, the vSAN administrator should remove the existing vSAN disk group and physically replace the device. Then check to verify that the ESXi host automatically detects the new device Afterwards manually recreate the Disk Group. This is because when a cache drive fails, it affects the entire disk group that contains it, and vSAN does not allow removing only the cache drive from a disk group. Therefore, the administrator must remove the whole disk group before replacing the cache drive, and then recreate it with the new cache drive and the existing capacity drives. The other options are not correct. Physically replacing the failed cache drive without removing the disk group first might cause errors or inconsistencies in vSAN configuration. vSAN will not automatically create a new disk group or allocate storage after replacing a cache drive, as these actions require manual intervention from the administrator.
Rebalancing the cache layer is not necessary after replacing a cache drive, as vSAN will automatically distribute data across all devices in the disk group. References: Replace a Flash Caching Device on a Host; How to manually remove and recreate a vSAN disk group using esxcli
NEW QUESTION # 43
A customer wishes to host a new range of applications with high-performance requirements, specifically, low latency. The current vSAN platform is based on ReadyNode hardware and uses a vSAN 7.0 U2 hybrid topology configuration.
Which would satisfy the customer's requirement?
Answer: A
Explanation:
Explanation
Deploying the application on a new cluster with vSAN 8.0 ESA using a new hardware design is the correct answer because it will satisfy the customer's requirement for low latency. vSAN 8.0 ESA is a new architecture that uses a storage pool configuration where all disks are treated as capacity disks and use a new algorithm to distribute data across them. This improves the I/O flow, reduces the write amplification, and eliminates the cache tier bottleneck. Using a new hardware design with all-flash disks or NVMe disks will further enhance the performance and latency of the application, as these disks have faster read and write speeds than hybrid disks. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additionalstripe width of 4, deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration, and performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA are not valid or optimal solutions for this scenario. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4 will increase the resiliency and availability of the data, but it will also increase the network traffic, disk space consumption, and parity calculation overhead, which will negatively affect the latency and performance of the application. Deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration will not improve the latency significantly, as vSAN 8.0 OSA still uses the same disk group configuration as vSAN 7.0 U2 OSA, where one disk is designated as a cache disk and the rest are capacity disks. The cache disk can still become a bottleneck for high-performance applications, especially if it is not an SSD or NVMe disk. Performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA is not possible, as vSAN ESA requires a different hardware design than vSAN OSA. The existing disk groups need to be deleted and all disks need to be erased before switching to vSAN ESA. References:

NEW QUESTION # 44
A host in a vSAN stretched cluster goes offline during an unplanned event.
Which action will be triggered from AQC on the vSAN cluster?
Answer: C
Explanation:
Explanation
When a host in a vSAN stretched cluster goes offline, vSAN will use Adaptive Resync to recalculate the quorum on an object. Quorum is the minimum number of votes that an object needs to be available. For example, a RAID-1 object with two data components and one witness component needs two votes out of three to be available. If one data component goes offline, the object still has quorum and is available. However, if both data components go offline, the object loses quorum and is unavailable. Adaptive Resync will adjust the quorum requirement based on the availability of components and fault domains. For example, if one fault domain goes offline, Adaptive Resync will lower the quorum requirement to one vote out of two, so that the object can remain available with one data component and one witness component.

NEW QUESTION # 45
Which VMware solution requires vSAN usage?
Answer: B
Explanation:
Explanation
The VMware solution that requires vSAN usage is VMware Cloud Foundation. VMware Cloud Foundation is an integrated software stack that bundles compute virtualization (VMware vSphere), storage virtualization (VMware vSAN), network virtualization (VMware NSX), and cloud management and monitoring (VMware vRealize Suite) into a single platform that can be deployed on premises or as a service within a public cloud.
VMware Cloud Foundation relies on vSAN as the primary storage solution for its workload domains, which are logical pools of resources that can be used to run different types of workloads. The other options are not correct. VMware Horizon, VMware Telco Cloud Automation, and VMware Aria Automation are VMware solutions that do not require vSAN usage, although they can benefit from it. VMware Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, and it can use any supported storage solution, including vSAN. VMware Telco Cloud Automation is a cloud-native orchestration and automation platform that enables communication service providers to accelerate the deployment and lifecycle management of network functions and services across any network and cloud. It can use any supported storage solution, including vSAN. VMware Aria Automation is not a valid VMware solution name.
