Q33. Which of the following statements about basic concepts in data center network is incorrect?

A leaf node is a fabric network function access node and provides various network devices to access a VXLAN network

Spine nodes are core nodes on the fabric network. They provide high-speed IP forwarding and conned to leaf nodes using high-speed interfaces in any scenario, spine nodes do not need to support VXLAN

The overlay technology is a tunnel encapsulation technology, such as VXLAN The basic principle is that packets are encapsulated in tunnel encapsulation mode, transparently transmitted on the underlying network, and then decapsulated to obtain original packets after reaching the destination. This is equivalent to a network overlay (overlay) on the underlying network.

The underlay network is a bearer network consisting of various physical devices, such as TOR switches, aggregation switch core switches, load balancing devices and firewalls

Explanation
Spine nodes are core nodes on the fabric network, but they do need to support VXLAN in some scenarios.
According to the Data Center Networking: What It Is, Why It Matters, And Types article, VXLAN is a tunnel encapsulation technology that allows overlay networks to be created on top of the underlay network. Spine nodes need to support VXLAN when they act as gateways between different overlay networks or between overlay and underlay networks.

Q34. HyperCDP objects can be used to restore data but cannot be directly mapped to hosts for read and write operations.

True

False

Q35. Which statements about dynamic reconstruction are true? (Multiple choice)

The data redundancy decreases.

Dynamic reconstruction is faster than ordinary reconstruction.

The number of RAID members decreases.

The number of RAID members remains unchanged.

Q36. What is the IO model for Vdbench performance testing on the test of “Random Read and Write Performance (With Data Reduction)?

16KB_70%Read_100% Random

8KB_100%Read_70%Radom

8KB_70%Read_100%Random

Q37. The system availability is 99.999%, indicating that the annual interruption time of the storage array is about 5 minutes.

True

False

Q38. Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices.

True

False

Explanation
Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.

Q39. In static-priority arbitration mode, if the active-active relationships are functional, but all replication links between storage arrays are down, what will happen?

Services stop at the preferred site while they continue at the non-preferred site

Services continues at the preferred site while they stop at the non-preferred site

Services stop at both the preferred and non-preferred sites

Services continues at both the preferred and non-preferred sites

Q40. To configure HyperMetro for LUNs that are carrying host services, you must first stop the host services.

True

False

Q41. Which statements about FusionStorage are true? (Multiple Choice)

It employs a distributed cluster architecture.

It stores metadata in metadata nodes.

It provides background data consistency checks.

It can be scaled out to a maximum of 4096 nodes.

Q42. Which of the following statements about LAN-WAN convergence b false?

WAN-side services set VPNs on the egress gateway for Interconnection between LAN sites

LAN-side services at the core, aggregation and access layers provide authentication for wired and wireless users on the campus network

You can configure interfaces and routes between the core switch and the egress gateways to achieve Interconnection between LAN and WAN services.

The WAN-side controller can manage both LAN and WAN.

Explanation
The WAN-side controller can manage only WAN services, not LAN services. The LAN-side controller can manage both LAN and WAN services. This is because the LAN-side controller supports both SD-WAN and SD-Campus functions, while the WAN-side controller only supports SD-WAN functions.

Q43. OceanStor 100D uses NVDIMMs as cache, which can prevent data loss during power failure.

Yes

Q44. The OceanStor OS has multiple innovative technologies to improve storage system reliability, including Huawei RAIG2.0+, SmartMatrix2.0, and HypenMetro.

True

False

Q45. How many remote devices does OceanStor 100D HyperReplication support at most?

Q46. What is the maximum single-radio rate supported by Wi-Fi 6 products?

0.6 Gbit/s

2.63 Gbit/s

8.75Gbit/s

9.6 Gbit/s

Explanation
The maximum single-radio rate supported by Wi-Fi 6 products is 9.6 Gbit/s. This is achieved by using
1024-QAM modulation, 160 MHz channel bandwidth, and 8 spatial streams1

Q47. Which statement about the ROW technology for OceanStor V5 is true?

Block snapshots use the ROW technology

ROW-based snapshots do not have extra data copies, and therefore the performance is better.

One of the advantages of ROW is that it does not easily generate data fragments
