Question 1
SIMULATION
A PowerMax array has been added to the environment. As part of the configuration, a weekly backup
is done every Sunday during the 8:00 AM hour. The load for all components during the backup
window should not be in system-level compliance calculations.
Using the simulator, set a recurring exclusion window at the system level on the array for the backup
window.
Answer:
See the
explanation for step
by step solution.
Explanation:
Okay, I understand. We need to configure a recurring exclusion window in the Unisphere for
PowerMax simulator to exclude performance load during a weekly backup that occurs every Sunday
from 8:00 AM to 9:00 AM. This exclusion will prevent the backup load from affecting system-level
compliance calculations.
Here's a step-by-step guide on how to do this, based on typical Unisphere functionality:
Steps:
1. Launch the Simulator and Navigate to the System Settings
Open Unisphere for PowerMax in your web browser.
Log in to the simulator (you should already be logged in with the array SID 1762 selected, based on
the image).
In the left-hand navigation pane, locate the settings or configuration section. The exact location
might vary slightly, but it's often found under:
Home > System Settings
Settings (an icon representing settings, like a gear)
Admin > System
In this instance, click the gear icon on the top right corner of the Unisphere interface.
2. Find the Exclusion Window Settings
Within the system settings, look for a section related to performance monitoring, metrics, or
thresholds.
Within this section, search for an option to configure "Exclusion Windows," "Scheduled Exclusions,"
or something similar. The exact name may vary.
3. Create a New Exclusion Window
Click on a button or link to create a new exclusion window. This might be labeled:
"Create"
"Add"
"+" (a plus icon)
A new window or panel will appear, allowing you to configure the exclusion window settings.
4. Configure the Exclusion Window Settings
Name (Optional): You can give the exclusion window a descriptive name, such as "Weekly Backup
Exclusion."
Type: Select "Recurring" or "Repeating" as the exclusion window type.
Schedule:
Day of the Week: Select "Sunday".
Start Time: Set the start time to 08:00 (or 8:00 AM). Make sure the time is in 24-hour format or that
you correctly select AM if using 12-hour format.
End Time: Set the end time to 09:00 (or 9:00 AM).
Scope/Target: Since we want this exclusion to apply at the system level, make sure the scope is set to
"System" or the entire array (SID 1762 in this case). You might not need to explicitly select this if
system-level is the default.
Components/Metrics: In some Unisphere versions, you can choose which components or metrics to
exclude. In our case, we want to exclude the load for "all components." If there's an option to select
components, either choose "All" or leave it at the default (which likely includes all components).
5. Save the Exclusion Window
After configuring all the settings, review them carefully to make sure they are correct.
Click the button to save the exclusion window. This might be labeled:
"Create"
"Save"
"OK"
"Apply"
6. Verify Exclusion Window Creation (Optional)
After the exclusion window is created, you can usually verify its settings in the exclusion window list.
You should see the new exclusion window listed with the correct schedule (Sunday, 8:00 AM - 9:00
AM) and scope (system level).
Question 2
SIMULATION
Your organization is preparing for a major software update, and it is crucial to ensure data integrity

"SnapVX"
Or an icon representing snapshot creation.
Click the appropriate button or icon to start the snapshot creation process.
4. Configure Snapshot Settings
A new window or panel will appear, allowing you to configure the snapshot settings.
Snapshot Name: Enter Stor1 as the snapshot name.
Snapshot Technology: Select SnapVX (or a similar option) as the snapshot technology.
Secure Snapshot: This is crucial. Look for an option labeled "Secure Snapshot," "Enable Secure Snap,"
"Secure Snap," or something similar. Check this option.
Retention/Expiration: You need to set the retention period for the secure snapshot. This will define
how long the snapshot cannot be deleted. There are usually a few ways to configure this:
Expiration Time: Set an explicit expiration date and time that is two days from now.
Retention Period: Specify a retention period of 2 days.
No Expiry: This option is not what we want here. We want the snap to be secure for 2 days.
Choose the appropriate option to make the snapshot undeletable for two days.
Other Settings: Review any other available settings. You might be able to choose between creating a
new snapshot or linking to an existing one. Select the option to create a new snapshot.
5. Create the Snapshot
After configuring all the snapshot settings, review them carefully to ensure they are correct.
Click the button to create the snapshot. This button might be labeled:
"Run Now"
"OK"
"Create"
"Finish"
6. Verify Snapshot Creation (Optional)
After the snapshot creation operation completes, you can verify that the snapshot was created
successfully:
Go back to the "StorGroup1" details view.
Look for a tab or section related to snapshots (e.g., "Snapshots," "TimeFinder," "Local Replication").
You should see the "Stor1" snapshot listed there, and its status should indicate that it's a secure
snapshot with the correct retention period (2 days).

Log in with your administrator credentials.
Step 2: Navigate to Storage Groups
In the left-hand navigation pane, click on Storage to expand the storage management section.
Click on Storage Groups under the Storage section. This will display a list of existing storage groups
on your PowerMax array.
Step 3: Locate the Target Storage Group
Identify the storage group that currently contains the host's existing two 100 GB volumes.
Tip: You can find this by:
Looking at the "Hosts" tab within each storage group's details. It will list the hosts connected to that
storage group.
If you know the host's name, you might be able to search for it using the Unisphere search bar (if
available).
Step 4: Initiate Adding Volumes
Once you've found the correct storage group, select it by clicking on its name.
Look for a button or option related to adding volumes. The exact wording might vary slightly
depending on your Unisphere version, but it could be:
"Add to Storage Group"
"+" (a plus icon, which often signifies adding something)
"Add Volumes"
Click this button to start the process of adding new volumes to the storage group.
Step 5: Configure Volume Details
A new window or panel will appear, allowing you to specify the characteristics of the new volumes.
Select "Create new volumes"
Number of Volumes: Enter 3 in the field for the number of volumes.
Capacity: Enter 100 in the field for the capacity of each volume. Make sure the unit is set to GB.
Volume Name (Optional): You can give the volumes a specific name or prefix, or you can let
Unisphere auto-generate names.
Service Level: Since the final goal is to move the entire Storage Group to platinum, you can either set
this to platinum now or change it for the whole group later.
Other Settings: Review any other available settings (e.g., thin provisioning, data reduction). In most
cases, the default settings should be fine, but adjust them if needed based on your environment's
best practices.
Step 6: Execute Volume Creation
After you've configured all the volume settings, review them carefully to make sure they are correct.
Click the button to execute the operation. This button might be labeled:

Step 10: Save the Changes
Click the button to save the changes to the storage group's service level. This button might be
labeled:
"Apply"
"Save"
"OK"
Phase 3: Host-Side Configuration
Step 11: Rescan for New Storage on the Host
The host needs to be made aware of the newly provisioned storage. The exact process for this
depends on the host's operating system:
Windows:
Open Disk Management (diskmgmt.msc).
Go to Action > Rescan Disks.
Linux:
Identify the SCSI host bus numbers (e.g., ls /sys/class/scsi_host).
Use the command echo "- - -" > /sys/class/scsi_host/hostX/scan, replacing hostX with the appropriate
host bus number.
You might also be able to use tools like rescan-scsi-bus.sh.
VMware ESXi:
In the vSphere Client, select the host.
Go to Configure > Storage Adapters.
Select the relevant storage adapter (e.g., your HBA).
Click Rescan Storage.
Step 12: Initialize, Partition and Mount (if needed):
Once the host detects the new volumes, you'll need to initialize them, create partitions, format them
with a filesystem, and mount them, depending on your operating system and how you intend to use
the storage. This is done using the host's operating system tools.
Phase 4: Verification and Monitoring
Step 13: Verify in Unisphere
Go back to the storage group in Unisphere and check the "Volumes" tab. You should see the three
new 100 GB volumes listed along with the original two, and they should all have the "Platinum"
service level.
Step 14: Verify on the Host
Confirm that the host can see and access the new volumes.
Step 15: Monitor Performance
After making these changes, monitor the performance of the storage group and the application using
Unisphere's performance monitoring tools. Ensure that the Platinum service level is meeting your
application's requirements

- A. Unisphere credentials and hostname
- B. IP address and hostname
- C. IP address and ESXi server credentials
- D. ESXi server credentials and Unisphere credentials
Answer:
C
Explanation:
Step by Step Comprehensive Detailed
To register an ESXi server in Unisphere for PowerMax, you need to provide the following information:
IP Address: The IP address of the ESXi server that you want to manage. This allows Unisphere to
communicate with the ESXi host.
ESXi Server Credentials: The username and password of an account with sufficient privileges to
access and manage the ESXi server. This ensures that Unisphere has the necessary permissions to
perform storage-related operations on the ESXi host.
Why other options are incorrect:
A . Unisphere credentials and hostname: Unisphere credentials are used to log in to Unisphere itself,
not to register an ESXi server.
B . IP address and hostname: While the hostname might be helpful, the ESXi server credentials are
essential for authentication and authorization.
D . ESXi server credentials and Unisphere credentials: Unisphere credentials are not required for
registering an ESXi server.

- A. Collects and manages performance statistics.
- B. Coordinates storage array locks and application syscalls
- C. Starts the system watchdog timer periodically
- D. Performs remote Solutions Enabler API functions.
Answer:
A
Explanation:
Step by Step Comprehensive Detailed
Solutions Enabler (SE) uses various daemons (background processes) to perform different functions.
The storstpd daemon is specifically responsible for:
Collecting Performance Statistics: It gathers performance data from the connected storage arrays,
such as I/O rates, response times, and other metrics.
Managing Performance Data: It stores and manages the collected performance statistics, making
them available for monitoring and analysis through tools like Unisphere for PowerMax.
This data is crucial for understanding the performance of the storage arrays, identifying potential
bottlenecks, and optimizing storage resources.
Why other options are incorrect:
B . Coordinates storage array locks and application syscalls: This is the function of the storapid
daemon.
C . Starts the system watchdog timer periodically: This is not directly related to the storstpd daemon.
D . Performs remote Solutions Enabler API functions: This is typically handled by the storsrvd

Question 12
From an application perspective, what should be done before performing an SRDF/S Restore
operation?
- A. Continue accessing the R1 devices Stop accessing the R2 devices.
- B. Stop accessing the R1 devices Continue accessing the R2 devices
- C. Stop accessing the R1 and R2 devices.
- D. Continue accessing the R1 and R2 devices
Answer:
C
Explanation:
Step by Step Comprehensive Detailed
Before performing an SRDF/S (synchronous) Restore operation, it is crucial to stop all host I/O activity
to both the R1 (source) and R2 (target) devices. This ensures data consistency and prevents potential
data loss or corruption during the restore process.
Here's why:
Data Integrity: An SRDF/S Restore operation involves copying data from the R1 device to the R2
device, overwriting any existing data on R2. If hosts are actively accessing and modifying data on
either device during this process, it can lead to inconsistencies and data integrity issues.
Synchronization: SRDF/S maintains real-time synchronization between the R1 and R2 devices. 1
Performing a Restore operation while hosts are writing data can disrupt this synchronization and lead
to unpredictable results.
Why other options are incorrect:
A . Continue accessing the R1 devices. Stop accessing the R2 devices: This would leave R1 vulnerable
to data inconsistencies.
B . Stop accessing the R1 devices. Continue accessing the R2 devices: This would make R2 susceptible
to data loss or corruption.
D . Continue accessing the R1 and R2 devices: This is the most dangerous option, as it would likely
lead to data integrity issues.

Question 13
What is the default size of a Gatekeeper on a PowerMax array1?
- A. 3 KB
- B. 3 cylinder
- C. 6 KB
- D. 6 cylinder
Answer:
B
Explanation:
Step by Step Comprehensive Detailed
A Gatekeeper in PowerMax is a small, dedicated device used for communication between the
storage array and Solutions Enabler (SYMCLI), the command-line management interface. The default
size of a Gatekeeper on a PowerMax array is 3 cylinders.
While the size can technically be specified in kilobytes (KB), the traditional and preferred unit for
Gatekeeper size is cylinders. This is because cylinders represent a specific number of blocks on the
physical disks, and using cylinders helps ensure consistent sizing across different disk types and
configurations.
Why other options are incorrect:
A . 3 KB, C. 6 KB: These sizes are too small to be practical for a Gatekeeper.
D. 6 cylinder: While older VMAX models might have used 6 cylinders, the current default for
PowerMax is 3 cylinders.

Question 14
What is the maximum capacity per array in a PowerMax 8500?
- A. 8 PBe
- B. 18 PBe
- C. 20 PBe
- D. 24 PBe
Answer:
D
Explanation:
Step by Step Comprehensive Detailed
The PowerMax 8500 is a high-end storage array designed for enterprise environments with
demanding capacity requirements. The maximum capacity per array in a PowerMax 8500 is 24
petabytes effective (PBe).
This means that after considering data reduction technologies like deduplication and compression,
the array can store up to 24 petabytes of usable data.
Why other options are incorrect:
A . 8 PBe, B. 18 PBe, C. 20 PBe: These values are lower than the actual maximum capacity of the
PowerMax 8500.

Question 15
What function can a storage administrator enable on the Port Attributes page?
- A. Manage Protocol
- B. Select Mgt Option
- C. Volume Set Addressing
- D. ORS Ceiling
Answer:
B
Explanation:
Step by Step Comprehensive Detailed
The Port Attributes page in Unisphere for PowerMax allows storage administrators to configure
various settings related to the front-end ports on the storage array. One of the functions available on
this page is Select Mgt Option.
This option allows you to specify how the port is used for management purposes:
Dedicated Management Port: You can designate a port as a dedicated management port, which is
used exclusively for communication with management tools like Unisphere and Solutions Enabler.
Shared Management Port: You can configure a port to be shared for both management traffic and
host I/O traffic.
This flexibility allows you to optimize port usage and segregate management traffic if needed.
Why other options are incorrect:
A . Manage Protocol: Protocol settings (like FC or iSCSI) are typically configured elsewhere in
Unisphere, not on the Port Attributes page.
C . Volume Set Addressing: Volume Set Addressing is a feature related to mainframe connectivity and
is not directly managed through the Port Attributes page.
D . ORS Ceiling: ORS (Open Replicator Solutions) settings are managed separately and not through
the Port Attributes page.
