NO.112 Dorado V6 supports both scale-out and scale-up.

True

False

NO.113 Which technique is used to protect end-to-end data integrity?

DIX+T10

CRC

SHA

NO.114 Which technology can provide real-time service quality visualization and minutes-level fault demarcation?

BFD

TI-LFA

TWAMP

iFIT

Explanation
iFIT is a technology that can provide real-time service quality visualization and minutes-level fault demarcation. It can collect and analyze network traffic data, identify network problems, and optimize network performance. iFIT uses Telemetry to collect data from network devices, and uses Network Cloud Engine (NCE) to process and display the data. iFIT can also use In-band Network Telemetry (INT) to embed data into packets for more accurate measurement.

NO.115 Which statement about the replication network between storage arrays in an active-active (HyperMetro) network is NOT true?

The active-active (HyperMetro) replication network supports the FC network

The active-active (HyperMetro) replication network supports the IP network

The active-active (HyperMetro) replication network bandwidth must be larger than the average service bandwidth

Each controller of active-active (HyperMetro) arrays has at least two redundant links

NO.116 Which is the scale-out networking protocol that OceanStor Dorado V6 supports?

RoCE

PCIe

NO.117 Which statement about the recommended deployment of the quorum device is true?

Deploy the quorum device at the preferred site.

Deploy the quorum device at the non-preferred site.

Deploy the quorum device at the third-place site.

Do not deploy the quorum device.

NO.118 The HyperMetro architecture of OceanStor Dorado V6 belongs to which of the following categories?

Active-active gateway-free

Active-active gateway

Active-passive gateway-free

Active-passive gateway

NO.119 Dorado V6 LUNs have controller ownership.

True

False

NO.120 Which disaster recovery solutions can Huawei Dorado V6 provide for customers? (Multiple Choice)

Async. Storage replication solutions

Sync. Storage replication solutions

Active-active solutions

CDM solution with near real-time, continuous data protection

DR-Star networking solutions

NO.121 Which reliability technologies are used in Huawei all-flash storage? (Multiple choice)

RAID

Bad block management

Power failure protection

Wear leveling

NO.122 What facts can be used to clear customers’ security concerns about SmartIDC-Grad (Information Collection) ? (Multiple Choice)

No plug-in is installed.

Only open APOs and CLI commands of the collected devices are invoked.

SmartIDC-Grab has been tested and certified by professional antivirus and security vulnerability scan tools.

Success stories

NO.123 Which is NOT the arbitration granularity supported by HyperMetro arbitration?

HyperMetro vStore pair

HyperMetro vStore consistency group

HyperMetro LUN pair

HyperMetro LUN consistency group

NO.124 Why does NVMe provide better performance than SAS? (Multiple choice)

The CPU can directly access devices through NVMe. There is no need for SAS protocol conversion

Interaction times of the NVMe protocols are only half that of the SAS protocols

The NVMe architecture supports increased I/O concurrency

None of the above

NO.125 Which of the following statements about the Leader AP feature is incorrect?

The leader AP establishes a CAPWAP tunnel with the fit AP

In tunnel forwarding mode, user traffic needs to pass through the leader AP

In direct forwarding mode user traffic is directly transmuted from the AP egress rather than from the leader AP

In tunnel forwarding mode the leader AP can manage more Fit APs.

Explanation
The leader AP does not establish a CAPWAP tunnel with the fit AP. The leader AP communicates with the fit AP through the management VLAN, and the fit AP establishes a CAPWAP tunnel with the AC. In tunnel forwarding mode, user traffic needs to pass through the leader AP. In direct forwarding mode, user traffic is directly transmitted from the AP egress rather than from the leader AP. In tunnel forwarding mode, the leader AP can manage more fit APs than in direct forwarding mode.

NO.126 Which replication link types do Huawei active-active (HyperMetro) solution support? (Multiple choice)

Fiber Channel

InfiniBand

SAS

NO.127 Which of the following statements about LUN mapping on Dorado V6 is incorrect?

New LUN groups can be directly mapped to a host.

A mapping view must be created.

LUNs or LUN groups can be created on the host mapping page

New LUNS can be directly mapped to a host or added to a LUN group (which has been mapped to a host)

NO.128 In an active-active (HyperMetro) network, which network types are supported between hosts and storage arrays? (Multiple choice)

HyperMetro SAN supports the FC network

HyperMetro SAN supports the IP network.

HyperMetro NAS supports the FC network.

HyperMetro NAS supports the IP network.

NO.129 Which of the following network architectures can Huawei provide in the DR solution in geo-redundant mode? (Multiple choice)

Serial

Parallel

Star

Delta Resync

NO.130 Which statement about the Dorado’s global garbage collection (GC) are correct? (Multiple choice)

Dorado supports intelligent adjustment of multiple GC levels based on the garbage percentage and CPU usage.

When a conflict cocurs, user I/Os and metadata always have a higher priority than GC.

Global GC issues TRIM commands to trigger GC on SSDs.

NO.131 Each AP needs to be designed to cover as large an area as possible in order to provide better coverage In a high-density scenario

True

False

Explanation
Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

NO.132 Which of the following contribute to the high reliability of Dorado high-end systems? (Multiple Choice)

Front-end and back-end interconnect (shared) I/O modules

Smart DAE

FastWrite

NDU

NO.133 The Dorado supports HyperMetro (active-active).
Which statements are true? (Multiple Choice)

Gateway-free active-active, low cost, fewer fault points, and shorter latency

Load balancing between sites with zero RPO and close-to-zero RTO

Easy to expand and upgrade to 3DC, which provides reliable data protection without data migration

VMs cannot be used as quorum servers.

The Dorado can use HyperMetro to work with OceanStor V5 hybrid storage to establish a 3DC deployment mode, red using customers TCO.

NO.134 Which of the following statements are correct about the performance test of Dorado V6 mid-range product models on a Fiber Channel network? (Multiple choice)

Dorado V6 delivers similar performance when using RAID 5, RAID 6, and RAID-TP.

The test performance of a single LUN on Dorado V6 can reach over 80% of the system performance.

The performance when native multipathing software is used is similar to that when UltraPath is used.

NO.135 Which of me following technologies can be used to switch the number of RFs dynamically?

OFDMA

SDR

MU-MIMO

1024-QAM

Explanation
SDR (Software Defined Radio) is a technology that can be used to switch the number of RFs (Radio Frequencies) dynamically. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, SDR enables an AP to dynamically switch between 2.4 GHz and 5 GHz bands based on the number of users and service requirements, improving spectrum utilization and user experience.
