CloudEngine S7700 switches support service port clustering and CSS2 switch fabric clustering.
- A. False
- B. True
Answer: B
Explanation:
Explanation
CloudEngine S7700 switches support service port clustering and CSS2 switch fabric clustering. According to the CloudEngine S7700 Series Switches Datasheet, service port clustering enables multiple physical ports to form a logical port that provides higher bandwidth and link redundancy, while CSS2 switch fabric clustering enables multiple switches to form a logical switch that provides higher performance and simplified management.

NEW QUESTION # 104
Which technology can provide real-time service quality visualization and minutes-level fault demarcation?
- A. TWAMP
- B. iFIT
- C. TI-LFA
- D. BFD
Answer: B
Explanation:
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.
NEW QUESTION # 105
Which of the following statements about basic concepts in data center network is incorrect?
- A. 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
- B. 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.
- C. 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
- D. A leaf node is a fabric network function access node and provides various network devices to access a VXLAN network
Answer: A
Explanation:
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.
NEW QUESTION # 106
The OceanStor Os's data plane and management plane are isolated from each other. Faults on either plane will not affect the other plane
- A. False
- B. True
Answer: B
NEW QUESTION # 107
Which of the following switches Goes not support iStacK?
- A. S5735-S
- B. S5731-H
- C. S1730S-H
- D. S5732-H
Answer: C
Explanation:
Explanation
The switch that does not support iStack is S1730S-H. This is because the S1730S-H does not have any stack ports or support stack cards. The iStack technology allows multiple switches to be connected and managed as a single logical device, which improves network scalability and reliability.
NEW QUESTION # 108
Which of me following technologies can be used to switch the number of RFs dynamically?
- A. MU-MIMO
- B. OFDMA
- C. 1024-QAM
- D. SDR
Answer: D
Explanation:
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.
NEW QUESTION # 109
In Huawel's CloudCampus Solution, communication between virtual networks (VNs) is supported which of the following statements about the policies tor such communication is false?
- A. Free mobility cannot be deployed for traffic between VNs
- B. Free mobility is supported for policies in a VN
- C. Communication between VNs can be directly implemented on the border node
- D. Communication between VNs can be implemented through the external firewall
Answer: A
Explanation:
Explanation
Free mobility cannot be deployed for traffic between VNs. Free mobility is supported only for policies in a VN. Communication between VNs can be directly implemented on the border node or through the external firewall. Free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a VN. Communication between VNs requires inter-VN routing or firewall policies to ensure security and isolation.
