質問 # 24
What are some possible network bottlenecks for a PowerProtect DD?

  • A. Routing protocols, switches and routers, and wire speeds
  • B. Connectivity, firewalls, and routing protocols
  • C. Configuration, wire speeds, switches and routers
  • D. Connectivity, routing protocols, and configuration

正解：C

解説：
In PowerProtect DD environments, network performance can be affected by various factors, and bottlenecks often arise from:
Configuration: Misconfigured network settings or incorrect protocols can limit the system's performance.
Wire speeds: The physical speed of the network cables (e.g., 1 GbE, 10 GbE) impacts data transfer rates.
Switches and routers: These network devices can introduce latency or limit bandwidth, especially if they are not optimized or if there are too many hops in the network path.
By addressing these areas, you can improve network throughput and ensure that the PowerProtect DD system is not constrained by network bottlenecks.

What should the engineer consider when cabling the hardware?

  • A. The DS60 shelf must be populated with identical drives
  • B. The DS60 shelf should be cabled on a separate chain
  • C. The FS25 shelf should be cabled on a separate chain
  • D. The FS25 shelf must be fully populated

正解：C


質問 # 28
What is a use case of BoostFS

  • A. To enable snapshot on DD Boost data
  • B. To increase DD Boost throughput
  • C. To protect applications that do not support DD Boost
  • D. To implement DD Boost over Fibre Channel

正解：C


質問 # 29
Refer to the exhibit.

To which shelf and port should SAS HBA slot 1 port B be connected?

  • A. Shelf 04 BH
  • B. Shelf 04 BE
  • C. Shelf 01 BE
  • D. Shelf 01 BH

正解：A


質問 # 30
An administrator recognizes poor network performance when using CIFS shares from a PowerProtect DD system. The network link utilization is under 100%. What is the most likely cause of this issue?

  • A. TCP window size too small
  • B. TCP timeout too small
  • C. TCP window size too large
  • D. TCP timeout too large

正解：A

解説：
Explanation: A small TCP window size can restrict data throughput, leading to suboptimal performance in CIFS-based file transfers. Adjusting the TCP window size can help maximize network bandwidth utilization and improve transfer speeds.


質問 # 31
Which protocol is used for communications between a PowerProtect DD appliance and cloud tier to Dell EMC ECS?

  • A. FTP
  • B. HTTPS
  • C. SSL
  • D. SSH

正解：B


質問 # 32
What is the preferred method to ensure backups are protected against deletion or corrupt?

  • A. Data Invulnerability Architecture
  • B. Dell EMC Cloud Tier
  • C. Retention Lock
  • D. Encryption

正解：A


質問 # 33
Which is required to store and manage archive data on a single PowerProtect DD appliance to comply with regulatory standards?

  • A. Retention Lock Governance
  • B. Encryption for Data at Rest
  • C. Retention Lock Compliance
  • D. Dell EMC Cloud Tier

正解：C


質問 # 34
What is the correct order of steps to verify DD Boost implementation and clone functionality?

質問 # 35
A PowerProtect DD appliance with two expansion shelves is being installed in a customer-provided rack.
When cabling the controller to the shelves, what is connected to the host port on the last shelf in the chain?

  • A. Expansion port of the controller
  • B. Expansion port of the upstream shelf
  • C. Host port of the controller
  • D. Host port of the downstream shelf

正解：B


質問 # 36
A customer requires a backup for their daily operational data. They do not back up directly to the PowerProtect DD appliance using Avamar backup software.
What will be the result of the backup process?

  • A. Data will be unable to restore locally
  • B. Backup server will preserve the data on the PowerProtect DD appliance
  • C. Backup process will be using post dedupe technology
  • D. Backup file will be available on cloud tier

正解：B


質問 # 37
A customer is attempting to configure VTL with 68 libraries, 800 slots, 524 drives, and 100 CAPs each but is unable to complete the configuration.
What is the cause of this issue?

  • A. Reached slots limit
  • B. Reached libraries limit
  • C. Reached drives limit
  • D. Reach CAPs limit

正解：B

解説：
PowerProtect DD appliances have specific limits on the number of libraries, slots, drives, and CAPs that can be configured. In this case, reaching the limit of 68 libraries likely exceeds the maximum allowed, preventing the configuration from being completed. Each component has its own limits, but in this scenario, the number of libraries is the bottleneck that prevents successful configuration.
