NEW QUESTION # 11
A customer has some CPU intensive applications running that will be deployed in the virtual machines. The customer is concerned that these virtual machines may impact the performance of the other virtual machines.
What should you recommend to avoid this potential problem and still leverage HPE SimpliVity features for these virtual machines?
- A. Deploy CPU intensive virtual machines on HPE SimpliVity, and configure for them CPU affinity parameter.
- B. Add an external ESXi system to HPE SimpliVity cluster, and enable DRS functionality for CPU intensive virtual machines.
- C. Present HPE SimpliVrty datastores to external ESXi system that will house these CPU intensive virtual machines.
- D. Add an external ESXi cluster to HPE SimpliVity Federation, and enable Intelligent Workload ptimizer.
Answer: A
Explanation:
According to the HPE SimpliVity Administration Guide1, one of the possible solutions to avoid the potential problem of CPU intensive applications impacting the performance of other virtual machines is to deploy the CPU intensive virtual machines on HPE SimpliVity, and configure for them CPU affinity parameter. This parameter allows you to specify which physical CPU cores are used by a virtual machine, and thus isolate the CPU intensive workloads from the rest of the virtual machines. This way, you can still leverage the HPE SimpliVity features, such as data efficiency, backup and restore, and federation management, for these virtual machines. The other options are not correct because:
Presenting HPE SimpliVity datastores to external ESXi system that will house the CPU intensive virtual machines is not a recommended solution, as it will reduce the data efficiency and availability benefits of HPE SimpliVity, and introduce additional complexity and overhead in managing the external ESXi system1.
Adding an external ESXi cluster to HPE SimpliVity Federation, and enabling Intelligent Workload Optimizer is not a recommended solution, as it will require additional hardware and software costs, and may not guarantee the optimal performance of the CPU intensive virtual machines, as the Intelligent Workload Optimizer is based on heuristics and not on strict rules2.
Adding an external ESXi system to HPE SimpliVity cluster, and enabling DRS functionality for CPU intensive virtual machines is not a recommended solution, as it will violate the HPE SimpliVity cluster requirements, and may cause issues with the HPE SimpliVity federation and data protection features1.

NEW QUESTION # 12
A customer is planning to deploy VDI infrastructure on HPE SimpuVity platform. They are considering implementing stretched cluster. Which statement regarding the design of a stretched cluster is true?
- A. Both Linked clones and Full clones are supported on a stretched cluster.
- B. An Arbiter should be placed in a primary site and replicated to the secondary site.
- C. Stretched clusters need additional licenses for VDI workloads,
- D. Stretched clusters support up to 96 HPE SimpliVity hosts.
Answer: A
Explanation:
A stretched cluster is a configuration that allows two or more HPE SimpliVity clusters to span across different physical locations, while maintaining a single logical cluster and asingle management interface. A stretched cluster provides high availability, disaster recovery, and workload mobility for the virtual machines (VMs) running on the HPE SimpliVity platform12.
A VDI infrastructure is a virtualization solution that delivers desktops and applications to end users from a centralized data center. VDI infrastructure can use different types of VMs, such as linked clones or full clones, to provide the desktops and applications to the end users. Linked clones are VMs that share a common base image and consume less storage space, while full clones are VMs that have their own independent copies of the base image and consume more storage space34.
According to the HPE Reference Architecture for VMware Horizon on HPE SimpliVity document, both linked clones and full clones are supported on a stretched cluster. The document states that "HPE SimpliVity supports both linked clones and full clones on a stretched cluster. Linked clones are recommended for better storage efficiency and performance. Full clones can be used for persistent desktops that require more customization and personalization."5 The document also provides the design considerations and best practices for deploying VDI infrastructure on HPE SimpliVity stretched cluster, such as the network requirements, the VM placement, the backup and restore policies, and the failover and failback scenarios.

NEW QUESTION # 13
At which level you can apply a backup policy?
- A. vCenter Server
- B. datacenter
- C. cluster
- D. datastore
Answer: D
Explanation:
You can apply a backup policy at the datastore level, as this is the level at which HPE SimpliVity manages the virtual machines and their backups1. A backup policy consists of one or more rules that specify the destination, frequency, and retention of the backups. You can assign a backup policy to a datastore, and all the virtual machines in that datastore will inherit the backup policy. You can also override the backup policy for individual virtual machines, if needed2. Applying a backup policy at the cluster level (option A), the datacenter level (option B), or the vCenter Server level (option C) is not possible, as these are not the levels at which HPE SimpliVity manages the virtual machines and their backups. These levels are used for organizing and managing the ESXi hosts and the HPE SimpliVity nodes, but not for applying backup policies.

NEW QUESTION # 14
A customer has development virtual machines that do not require storage HA. How can the customer save storage capacity within an HPE SimpliVity cluster?
- A. By disabling the HA feature for only these virtual machines at vCenter Server
- B. By placing them on HPE Storence instead of HPE SimpliVity
- C. By disabling HA cluster functionality for HPE SimpliVity Federation
- D. By creating a single-replica datastore for these virtual machines
Answer: D
Explanation:
HPE SimpliVity provides storage HA by creating two copies of each virtual machine data across different nodes in a cluster. This ensures that the virtual machines can continue to run even if one node fails. However, this also consumes twice the storage capacity for each virtual machine. For development virtual machines that do not require storage HA, the customer can save storage capacity by creating a single-replica datastore for these virtual machines. A single-replica datastore is a datastore that has only one copy of the virtual machine data on one node. This reduces the storage consumption by 50%, but also increases the risk of data loss and unavailability in case of node failure. Therefore, the customer should carefully weigh the trade-offs between storage efficiency and data protection when using a single-replica datastore.

NEW QUESTION # 21
You want to use the HPE SimpliVity move operation to move a virtual machine between clusters. What do you have to do prior to completing the move operation?
- A. Take a virtual machine snapshot.
- B. Suspend the virtual machine.
- C. Install VS5 agent in the virtual machine.
- D. Shut down the virtual machine.
Answer: A
Explanation:
Before moving a virtual machine to another datastore, you need to take a snapshot of the virtual machine using the HPE SimpliVity plugin in vSphere. This ensures that the virtual machine is in a consistent state and that the data is protected. The snapshot also serves as a backup in case the move operation fails or is interrupted.
After taking the snapshot, you can use the HPE SimpliVity move operation to move the virtual machine to the desired datastore, either within the same cluster or across clusters. The move operation preserves the data efficiency and resiliency of the virtual machine, and does not require any downtime or reconfiguration12.

NEW QUESTION # 23
A customer plans to add HPE SimpliVity 380 Gen10 H SFF nodes to their remote site. The primary site is running HPE SimpliVity 380 Gen10 hardware accelerated nodes. Which recommendation should be applied for this design?
- A. Create a new cluster with SimpliVity 380 Gen10 H SFF nodes.
- B. Create a new cluster and split Doth types of nodes equally between both clusters,
- C. Configure the HPE SimpliVity 380 Gen 10 H SFF with a hardware accelerator card.
- D. Add new nodes to the existing cluster
Answer: A
Explanation:
According to the HPE SimpliVity documents and learning resources, the best practice for designing an HPE SimpliVity solution is to use nodes with the same drive configuration and capacity within a cluster, and avoid mixing All-flash and hybrid nodes, or nodes with different drive types, sizes, or speeds. This is because mixing nodes with different drive configurations can result in unbalanced 10 performance and capacity utilization, as well as compatibility issues.Therefore, the recommended option for this design is to create a new cluster with HPE SimpliVity 380 Gen10 H SFF nodes at the remote site, and keep the existing cluster with HPE SimpliVity 380 Gen10 hardware accelerated nodes at the primary site. The other options are incorrect because they do not follow the best practice and can cause performance and capacity problems.

NEW QUESTION # 24
Which criteria does HPE SimpliVity use to decide how many streams it needs to copy data to an HPE Storence target?
- A. latency requirements
- B. available bandwidth
- C. datastore size
- D. VM size
Answer: B
Explanation:
HPE SimpliVity is a hyperconverged infrastructure solution that combines compute, storage, networking, and data services in a single platform. HPE SimpliVity integrates with HPE StoreOnce, a disk-based backup appliance, to provide efficient and reliable data protection and disaster recovery for distributed edge sites12.
HPE SimpliVity uses HPE StoreOnce Catalyst, a deduplication protocol, to replicate data from HPE SimpliVity clusters to HPE StoreOnce appliances. HPE SimpliVity leverages its global deduplication and compression capabilities to send only the unique data blocks to HPE StoreOnce, reducing the bandwidth and storage requirements34.
To optimize the replication performance, HPE SimpliVity uses a dynamic stream allocation algorithm that determines how many streams it needs to copy data to an HPE StoreOnce target. According to the HPE SimpliVity with HPE StoreOnce Reference Architecture document, the algorithm considers the following factors:
The available bandwidth between the source and the target
The latency between the source and the target
The size of the data to be replicated
The number of concurrent replication jobs
The document states that "The available bandwidth is the most important factor in determining the number of streams. The more bandwidth available, the more streams can be used to copy data. However, the number of streams is limited by the latency and the size of the data. If the latency is too high or the data size is too small, adding morestreams will not improve the performance." Therefore, the available bandwidth is the criteria that HPE SimpliVity uses to decide how many streams it needs to copy data to an HPE StoreOnce target.

target?
- A. latency requirements
- B. available bandwidth
- C. VM size
- D. datastore size
Answer: C
NEW QUESTION # 28
You try to delete an existing datastore, but the operation fails. What is a likely cause of the failure?
- A. This datastore is not added to your scope.
- B. The management network for a host is disconnected.
- C. The FC connection between the host and array has failed.
- D. The datastore is marked as read-only.
Answer: B
Explanation:
According to the HPE SimpliVity Video - How to Delete a HPE SimpliVity Datastore1, one of the possible causes of the failure to delete an existing datastore is that the management network for a host is disconnected.
This prevents the communication between the HPE SimpliVity federation and the vSphere Web Client, and thus the deletion operation cannot be performed. To check the management network status, the video suggests clicking Hosts from the vSphere Web Client inventory panel, double-clicking the host to check, clicking the Manage tab, and then the Networking subtab. The other options are not correct because:
The datastore being marked as read-only is not a likely cause of the failure to delete it. The HPE SimpliVity Administration Guide2 states that the datastore must be writable before deleting it, and that the HPE SimpliVity federation will automatically change the datastore to writable mode when deleting it.
The FC connection between the host and array failing is not a likely cause of the failure to delete the datastore. The HPE SimpliVity federation does not use FC connections to access the datastores, but rather uses NFS or SMB protocols over Ethernet networks2.
The datastore not being added to the scope is not a likely cause of the failure to delete it. The HPE SimpliVity federation does not require the datastore to be added to the scope to delete it, as long as the datastore is visible in the vSphere Web Client1.

- A. Additional license is required to connect ESXi nodes to SimpliVity datastores.
- B. Connecting ESXi compute nodes is possible only when VMFS datastores are configured at SimpliVity Federation level
- C. It is supported to connect up to 5 compute nodes per SimpliVity node.
- D. Compute nodes must reside in the same cluster as HPE SimpliVity nodes.
Answer: D
Explanation:
HPE SimpliVity allows customers to connect ESXi compute nodes to HPE SimpliVity datastores without additional license or configuration. This enables customers to leverage the data efficiency and protection features of HPE SimpliVity for their compute-intensive workloads. However, the compute nodes must reside in the same cluster as HPE SimpliVity nodes, and they must be authorized by HPE SimpliVity to access the NFS datastores. The number of compute nodes per cluster is limited by the maximum number of hosts supported by VMware vSphere.
