最新的 FlashArray Storage FlashArray-Storage-Professional 免費考試真題 (Q29-Q34):

問題 #29
An On-Premises ActiveCluster (AC) Mediator is installed on an ESXi server. The mediator was previously online but when the administrator checked the status of the ActiveCluster (AC) pods the mediator status was listed as "unreachable" for both FlashArrays in the ActiveCluster (AC) pair.
What is a possible cause of the mediator being unreachable from both FlashArrays?

答案：A

解題說明：
The ActiveCluster Mediator (whether it is the Pure1 Cloud Mediator or the On-Premises VM) is a lightweight tie-breaker that communicates continuously with the management interfaces of both FlashArrays. If it was previously online and suddenly reports as "unreachable" from both arrays simultaneously, the issue is almost always caused by a network interruption or firewall rule change blocking the required communication ports between the arrays' management IP addresses and the Mediator VM.
If a network firewall is suddenly configured to drop or deny outbound TCP traffic (such as port 80/443 depending on the specific HTTP/HTTPS discovery and heartbeat configuration) from the FlashArrays to the ESXi-hosted Mediator, the arrays will fail to send their heartbeats, causing the mediator status to drop to "unreachable." Here is why the other options are incorrect:
Fibre Channel (FC) zoning or network access has not been created properly for the host (A): The Mediator is completely independent of the front-end host storage fabric (Fibre Channel or iSCSI). Host zoning issues would prevent the ESXi server from seeing its volumes, but it would not cause the FlashArrays to lose management network connectivity to the Mediator.
The mediator does not reside within a Pure datastore (B): This is actually a strict best practice and requirement. Pure Storage explicitly states that the On-Premises Mediator VM must be deployed in a separate (third) failure domain. It should not reside on the ActiveCluster mirrored datastore, because a site-wide SAN failure would take the mediator offline exactly when it is needed most. Therefore, not residing on a Pure datastore is the correct setup, not a cause for an outage.


問題 #30
What does an asynchronous blackout window prevent?

答案：B

解題說明：
Definition of a Blackout Window: In Purity//FA, a Blackout Window is a scheduled period during which asynchronous replication is suspended. This is typically used by administrators to preserve WAN bandwidth during peak business hours or to prevent replication traffic from competing with high-priority local workloads (like a massive database batch job).
The "In-Progress" Rule: One of the most important characteristics of a blackout window is that it is non-disruptive to active transfers. If a replication job started at 7:55 AM and the blackout window begins at 8:00 AM, Purity will allow that specific transfer to continue until it finishes.
The Prevention Mechanism: Once the clock hits the start of the blackout window, the replication scheduler is effectively "paused." No new snapshots will be queued for transfer, and no new replication sessions will be initiated until the window expires.
Why Option A is incorrect: Purity does not kill active transfers. Abruptly stopping a transfer would waste the bandwidth already consumed and require the entire delta-set to be re-calculated or re-sent later.
Why Option B is incorrect: The phrasing is logically inconsistent; you cannot prevent something that "started before" the window from being "new" during the window.
Best Practice: When configuring blackout windows, ensure that the "clear" time (the time between windows) is long enough to allow the array to catch up on the snapshots that were queued during the blackout, otherwise, you risk triggering Alert 51 (Replication Delayed).


問題 #31
Which protection group cannot be ratcheted for SafeMode?

答案：B

解題說明：
What is SafeMode Ratcheting?: SafeMode is Purity's "immutability" feature that prevents snapshots from being deleted, eradicated, or modified, even by an administrator with compromised credentials. Ratcheting is the process of increasing the protection levels (like extending the retention period) for a protection group (pgroup) to ensure even stricter data safety.
The Dependency on Local Snapshots: SafeMode's primary function is to protect point-in-time copies of data residing on the array. For a protection group to be "ratcheted" into a SafeMode-protected state, it must have an active Local Snapshot Schedule.
Why Option C is the Constraint: If a protection group does not have a local snapshot schedule, there are no local snapshots being generated for SafeMode to "lock." SafeMode cannot protect what doesn't exist locally. While a pgroup might be used for replication only, SafeMode requires the local scheduling component to be active and configured to apply its immutable retention policies.
Why Option B is incorrect: Protection groups are designed to contain hosts, host groups, or volumes. This is the standard way to group related data for snapshot consistency and has no negative impact on SafeMode eligibility.
Operational Note: When you enable SafeMode on a protection group with a local schedule, the "Erradicate" button for those snapshots is disabled. To "ratchet" the protection, you typically work with Pure Storage Support to ensure the retention settings meet your compliance needs.


問題 #32
An on-premises mediator has been deployed. When a pod is stretched and replicating, it is observed that the pod is utilizing the Pure1 Cloud Mediator and not the on-premises mediator.
Why is the on-premises mediator NOT being used by this new pod?

答案：B

解題說明：
ActiveCluster Mediator Logic: In an ActiveCluster setup, the Mediator is a lightweight component (an "arbiter") that resides at a third site (failure domain). Its job is to break the tie in a "split-brain" scenario (when arrays lose connectivity with each other) to determine which array stays online.
Default Behavior: By default, every FlashArray is configured to use the Pure1 Cloud Mediator. This is a managed service provided by Pure Storage that requires no local infrastructure other than internet access from the array controllers.
On-Premises Mediator Deployment: Organizations that cannot use the Cloud Mediator (due to "dark site" security requirements or lack of reliable internet) can deploy the Pure Storage On-Premises Mediator as a small OVF/VM template.
Configuration at the Pod Level: Simply deploying the On-Premises Mediator VM and connecting the arrays to it at the array level is not enough for existing or new pods to switch automatically. In Purity, the mediator preference is a per-pod attribute.
When a pod is created or stretched, it inherits the default (Cloud).
To use the local mediator, the administrator must explicitly configure the pod to point to the On-Premises Mediator's IP or DNS name. This is done via the CLI using purepod setattr --mediator <address> <pod-name> or through the Pod settings in the GUI.
Why Option C is incorrect: While an A record is necessary for DNS resolution, the prompt implies the mediator is already "deployed" and available. The most common reason it isn't being used is simply that the pod hasn't been told to look there instead of the default Cloud option.


問題 #33
What is unified storage for Pure?

答案：C

解題說明：
Defining Unified Storage: In the storage industry, "Unified Storage" refers to a single storage platform that can simultaneously serve data over both block-level and file-level protocols.
The Pure Storage Approach: Historically, FlashArray was a high-performance block-only array. However, with the introduction of FlashArray File Services, Pure transitioned to a unified architecture. This means the same hardware (FlashArray//X, //C, or //XL) and the same management interface (Purity) handle both types of workloads.
Protocol Support:
Block Protocols: Fibre Channel (FC), iSCSI, and NVMe-over-Fabrics (NVMe-oF).
File Protocols: NFS (Network File System) and SMB (Server Message Block).
Why this is "Unified": * Shared Pool of Resources: Unlike older legacy systems that used "file gateways" or separate hardware heads for NAS, Pure's unified storage shares a single global pool of flash memory and deduplication metadata.
Ease of Management: Administrators don't need to manage two different systems. You can create a Volume (Block) or a File System (File) from the same "Add" menu in the GUI.
Why Options A and B are incorrect: * Option A only describes the File side of the equation.
Option B only describes the Block side of the equation.
Only Option C accurately captures the combination of both paradigms, which is the definition of "Unified."
