Answer: D
Explanation:
Explanation
Dielectric constant does not affect radio throughput. According to Shannon's theorem4, radio throughput is determined by the bandwidth and the signal-to-noise ratio of the channel. Dielectric constant is aproperty of the medium that affects the propagation speed and wavelength of electromagnetic waves, but not the information-carrying capacity.

Which of the following technologies is not recommended for data centers?
- A. BFD
- B. M-LAG
- C. VXLAN
- D. 802. 1x
Answer: D
Explanation:
Explanation
The technology that is not recommended for data centers is 802.1x. This is because 802.1x is a port-based authentication protocol that requires each device to be authenticated before accessing the network. This can cause delays and complexity in data center environments where there are many devices and high-speed connections2

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 # 27
Which of the following statement about the advantages of WPA3 is incorrect?
- A. Potential for dictionary attacks
- B. Open SSID data can be encrypted
- C. Meet NSA/SuiteB security requirements of governments and banks
- D. Even if the attacker obtains the intermediate key. the data cannot be decrypted
Answer: A
Explanation:
Explanation
WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases
. WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3.
WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .
NEW QUESTION # 28
Which of the following are benefits of front-end interconnect (shared) I/O modules? (Multiple choice)
- A. Fewer front-end modules and host links needed.
- B. Storage sysadmins are needed to ensure the multipath software in servers runs online before controller upgrades.
- C. Direct data dispatch to the distributed controllers through front-end modules in one controller enclosure.
- D. Host path loss prevention in the event of controller failure, controller hard/software upgrades, and even single FC 1 between host and storage.
Answer: A,D
NEW QUESTION # 29

Answer: B
NEW QUESTION # 30
In the headquarters-branch VXLAN Interconnection scenario, single-fabric networking is supported
- A. False
- B. True
Answer: A
Explanation:
Explanation
In the headquarters-branch VXLAN interconnection scenario, single-fabric networking is not supported.
According to the Huawei CloudCampus Solution Description, headquarters-branch VXLAN interconnection is a scenario that connects multiple campus networks over a WAN using VXLAN tunnels. In this scenario, each campus network forms an independent fabric network with its own controller and gateway devices.
Single-fabric networking is a scenario that connects multiple campus networks over a LAN usingVXLAN tunnels. In this scenario, all campus networks share the same fabric network with a unified controller and gateway devices.
