EMC Dell PowerScale Maintenance Exam Sample Questions (Q141-Q146):

NEW QUESTION # 141
In a Dell PowerScale Gen 6 cluster, which nodes work as a pair?

  • A. Nodes in slots 1 and 3
  • B. Nodes in slots 1 and 2
  • C. Nodes in slots 2 and 4
  • D. Nodes in slots 2 and 3

Answer: B


NEW QUESTION # 142
What type of upgrade on a Dell PowerScale cluster requires the least amount of time?

  • A. Automatic
  • B. Rolling
  • C. Simultaneous
  • D. Parallel

Answer: C

Explanation:
Asimultaneous upgradeon a Dell PowerScale cluster involves upgrading all nodes at the same time. This method requires the least amount of time compared to other upgrade types because it minimizes the total duration by handling the upgrade process concurrently across the entire cluster.
Types of Upgrades:
* Simultaneous Upgrade:
* Definition:All nodes are upgraded at the same time.
* Advantages:
* Fastest upgrade method.
* Reduces total upgrade time significantly.
* Disadvantages:
* Requires cluster downtime; not suitable for environments that need continuous availability.
* Rolling Upgrade:
* Definition:Nodes are upgraded one at a time or in small groups.
* Advantages:
* No cluster downtime; services remain available.
* Disadvantages:
* Takes longer to complete as each node is upgraded sequentially.
* Parallel Upgrade:
* Definition:Nodes are upgraded in parallel batches.
* Advantages:
* Balances upgrade speed and availability.
* Disadvantages:
* May still require some service interruption.
* Automatic Upgrade:
* Definition:The upgrade process is automated but follows the rolling or parallel methodology.
* Advantages:
* Reduces manual intervention.
* Disadvantages:
* Upgrade time depends on the underlying method used (rolling or parallel).
Why Simultaneous Upgrade Requires the Least Amount of Time:
* Concurrent Processing:Upgrading all nodes at once leverages parallelism, drastically reducing the total time needed.
* No Sequential Steps:Eliminates the wait time associated with upgrading nodes one after another.
* Use Case Considerations:Suitable for non-production clusters or environments where downtime is acceptable.
Important Considerations:
* Cluster Downtime:Simultaneous upgrades will render the cluster unavailable during the process.
* Risk Management:Any issues during the upgrade can affect the entire cluster; thorough planning and backups are essential.

NEW QUESTION # 143
What security mechanism is used in the OneFS API to encrypt communications?

  • A. SED
  • B. OpenSSH
  • C. HTTPS
  • D. RBAC

Answer: C

Explanation:
The OneFS API usesHTTPS(HyperText Transfer Protocol Secure) to encrypt communications, ensuring secure data transfer between clients and the PowerScale cluster.
* OneFS API and Security:
* OneFS API:
* Provides a RESTful interface for programmatically managing and interacting with the PowerScale cluster.
* Security Importance:
* Protects sensitive data and configuration information transmitted via the API.
* Use of HTTPS:
* Encryption:
* HTTPS uses TLS (Transport Layer Security) to encrypt data in transit.
* Prevents eavesdropping and man-in-the-middle attacks.
* Authentication:
* Supports certificate-based authentication to verify the identity of the server.
* Standard Protocol:
* Widely accepted and supported for secure web communications.
* Why Other Options Are Less Suitable:
* Option A (SED):
* Self-Encrypting Drives (SEDs) encrypt data at rest, not communications.
* Option B (RBAC):
* Role-Based Access Control (RBAC) manages user permissions and authorization, not encryption.
* Option D (OpenSSH):
* OpenSSH provides secure shell access, not used for the OneFS API communications.
* Implementing HTTPS with OneFS API:
* Default Behavior:
* OneFS API endpoints are accessed via HTTPS by default on port 8080 or 8080.
* Certificate Management:
* Administrators can install custom SSL certificates to ensure secure connections.
* API Calls:
* Applications interacting with the OneFS API must support HTTPS requests.
Dell PowerScale References:
* Dell EMC PowerScale OneFS API Reference Guide:
* Details on API usage and security considerations.
* Dell EMC PowerScale OneFS API Reference Guide
* Dell EMC PowerScale OneFS Security Configuration Guide:
* Provides information on configuring HTTPS and managing certificates.
* Dell EMC PowerScale OneFS Security Guide
* Knowledge Base Articles:
* Article ID 000123006:"Securing OneFS API Communications with HTTPS"
* Article ID 000123007:"Configuring SSL Certificates for OneFS API Access"


NEW QUESTION # 144
What phrase describes A-Series nodes?

  • A. All-flash arrays for ultra compute and high-capacity requirements that can accomplish 250-300k protocol operations per chassis
  • B. All-flash, versatile, hybrid platforms ideal for organizations that support a broad range of data archives on a single platform
  • C. Hybrid storage platforms that are highly flexible and provide support for a broad range of enterprise file workloads
  • D. Designed for data archival purposes and can be combined with new or existing all-flash and hybrid storage systems

Answer: D


NEW QUESTION # 145
What must be enabled in SMB to ensure nondisruptive upgrades?

  • A. SMB direct
  • B. SMB multichannel
  • C. SMB encryption
  • D. SMB continuous availability

Answer: D

Explanation:
To ensurenondisruptive upgradesin an SMB environment,SMB Continuous Availability (CA)must be enabled. SMB CA allows file shares to remain accessible without interruption during planned maintenance or unexpected node failures.
Key features of SMB Continuous Availability:
* Transparent Failover:
* Client sessions persist seamlessly when the SMB service fails over to another node.
* State Preservation:
* Open files, locks, and session states are maintained during the failover.
* High Availability:
* Enhances the cluster's ability to provide uninterrupted service.
Steps to enable SMB Continuous Availability:
* Verify OneFS Version:
* Ensure the cluster is running OneFS version that supports SMB 3.0 or higher.
* Enable SMB CA on the Cluster:
* Use the OneFS WebUI or CLI to enable Continuous Availability for SMB shares.
* Configure SMB Shares:
* Set the "Continuous Availability" option on the specific SMB shares that require it.
* Client Requirements:
* Clients must be running Windows 8 or Windows Server 2012 (or later) to support SMB CA.
By enabling SMB Continuous Availability, upgrades and maintenance can be performed without disrupting client access to file shares.
