Questions # 23:

After a performance analysis, a customer plan to reorganize his adaptive Flash cache (AFC)

configuration and want to raise it from 256 to 768GB. Which action is needed to take advantage of the new AFC configuration?

Options:

Remove flash cache for all VVS then run create Flash cache

Increase current AFC configuration to reflect the additional space

Remove the old AO configuration and recreate a new one

Run tunesys after raising the AFC to take advantage of the additional space

Answer

Explanation

When adjusting the Adaptive Flash Cache (AFC) configuration in HPE 3PAR StoreServ, particularly when increasing the cache size, the correct procedure involves first removing the existing flash cache for all Virtual Volumes (VVs). After this step, you should recreate the flash cache to reflect the new increased capacity. This ensures that the system properly recognizes and utilizes the additional cache space, optimizing performance according to the new configuration.

Questions # 24:

Recommend a software stack for changing a backup platform that includes pay-per-use, supports backup of virtualized workloads provided by HPE GreenLake, offers low RPO in minutes, supports HPE AUetra 9000, and integrates with DSCC.

Options:

Veeam Backup and Recovery

Recovery Manager Central

Zerto

HPE GreenLake Backup and Recovery

Answer

Explanation

HPE GreenLake Backup and Recovery is the recommended software stack for a backup platform that includes a pay-per-use model, supports virtualized workloads, and integrates with the HPE Data Services Cloud Console (DSCC). This solution offers low Recovery Point Objectives (RPOs) in minutes, supports HPE Alletra 9000, and provides the flexibility and scalability needed for modern backup environments. It is part of the HPE GreenLake ecosystem, which provides cloud-like agility and economics with on-premises control.

Questions # 25:

A solution architect is sizing the required capacity for an HPE Alletra 9000. Customer requirements include:

• 200TB base volumes

• Regular snapshots being taken every hour with one-week retention

• 10% daily change rate

How much capacity is needed for snapshots after one week?

Options:

480TB

140TB

200TB

20TB

Answer

Explanation

To calculate the required capacity for snapshots after one week for an HPE Alletra 9000 with the given customer requirements:

Base volume size: 200TB

Snapshots frequency: Every hour (24 snapshots per day, 168 per week)

Daily change rate: 10%

The snapshot capacity can be calculated by considering the daily change rate and the number of snapshots over a week.

Daily change: 10% of 200TB = 20TBTotal change over a week: 20TB * 7 days = 140TB

Since there are 168 snapshots (24 per day for 7 days), the total required capacity is 140TB (for the changes) plus the base volume size of 200TB, totaling 480TB.

Questions # 26:

Which file protocols are commonly used in HPE StoreOnce environments? (Choose two.)

Options:

CIFS

NTFS

VFS

ZFS

NFS

Answer

A, E

Explanation

In HPE StoreOnce environments, the two most commonly used file protocols are CIFS (Common Internet File System) and NFS (Network File System).

CIFS: This protocol is widely used in Windows environments for file sharing. It enables users and applications to access files on remote servers as if they were local, making it ideal for integration with Windows-based systems.

NFS: This protocol is commonly used in Unix and Linux environments for file sharing. It allows a user on a client computer to access files over a network much like local storage is accessed.

These protocols are integral to HPE StoreOnce's capability to provide flexible and efficient file-based backup and recovery solutions across different operating environments.

Questions # 27:

A solution architect is explaining RBAC concepts behind the HPE GreenLake Platform. How can the customer manage users in HPE GreenLake Platform after creating new company account?

Options:

HPE Support must be used to create an administrator account for the organization.

The creator of the company account is automatically assigned to the Account Administrator role for the organization.

Single company can only have one account.

The creator of the company account must create another account with Account Administrator role.

Answer

Explanation

In the HPE GreenLake Platform, when a new company account is created, the individual who creates the account is automatically assigned the Account Administrator role. This role grants them the ability to manage users, assign roles, and control access within the HPE GreenLake environment, ensuring that they have full administrative control over the account from the outset.

Options:

SATA interface chip

DRAM

NAND memory controller

Processor

Answer

Questions # 29:

Exhibit:

Question # 29

Which fabric design is shown?

Options:

meshed

single fabric

cascaded

core-edge

Answer

Explanation

The fabric design shown in the exhibit is a core-edge architecture. This design consists of core switches that are centrally located and connect to edge switches, which are distributed across the network. The core switches provide high-speed backbone connectivity, while the edge switches connect directly to storage devices or servers. This architecture is commonly used in SAN environments to provide scalability, manageability, and high availability.
