Huawei's CloudWAN 3.0 solution propels WANs into the intelligent cloud-network era. Which of the following are the key highlights of CloudWAN 3.0?

1. A. One-click maintenance
2. B. One-network wide connection
3. C. One-fiber multipurpose transport
4. D. One-click fast scheduling
5. E. One-hop cloud access

Correct Answer: BCE
Huawei's CloudWAN 3.0 solution is a next-generation WAN architecture designed to address the challenges of digital transformation and cloud adoption. The key highlights of this solution include:
One-network wide connection : CloudWAN 3.0 enables seamless connectivity across multiple sites, integrating various access technologies (e.g., MPLS, SD-WAN, and PON) into a unified network. This ensures efficient resource utilization and simplifies network management.
One-fiber multipurpose transport : This feature allows a single fiber to carry multiple services, such as Internet, voice, video, and private line services. It significantly reduces infrastructure costs and improves operational efficiency.
One-hop cloud access : CloudWAN 3.0 provides direct, low-latency access to cloud services through optimized routing. This enhances user experience and supports real-time
applications like video conferencing and online collaboration.
While "one-click maintenance" and "one-click fast scheduling" are valuable features in network management, they are not explicitly highlighted as part of the CloudWAN 3.0 solution in official Huawei documentation.

OSPF routers exchange link status information instead of directly exchanging routes.

1. A. TRUE
2. B. FALSE

Correct Answer: A
OSPF (Open Shortest Path First) is a link-state routing protocol. Instead of directly exchanging routes, OSPF routers share link-state advertisements (LSAs) that describe the state of their links (e.g., connected networks and costs). Each router uses this information to build a complete topology map of the network and calculate the shortest path to each destination using the SPF (Shortest Path First) algorithm.
The statement accurately describes how OSPF operates, making it TRUE . References:

Which of the following are factors affecting the wireless rate (throughput) of a Wi-Fi AP? (Select All that Apply)

1. A. CPU performance
2. B. SNR
3. C. Spatial stream
4. D. Frequency bandwidth

Correct Answer: ABCD
Factors Affecting Wireless Rate:
The wireless rate (throughput) of a Wi-Fi AP depends on multiple factors, including hardware capabilities, environmental conditions, and configuration settings. Explanation of Each Factor:
CPU performance:The AP's CPU processes data packets and performs tasks like encryption/decryption. Higher CPU performance enables better throughput.
SNR (Signal-to-Noise Ratio):A higher SNR indicates a stronger signal relative to noise, resulting in better data rates.
Spatial stream:Wi-Fi 6 supports multiple spatial streams (MIMO), increasing throughput by transmitting multiple data streams simultaneously.
Frequency bandwidth:Wider channels (e.g., 20 MHz, 40 MHz, 80 MHz, or 160 MHz) allow higher data rates but may increase interference in crowded environments.
Conclusion:All four options are factors that affect the wireless rate of a Wi-Fi AP. References:

Enterprise networks, no matter campus networks or DCNs, are facing a lot of potential attacks. What are the common types of attack methods we are facing? (Select All that Apply)

1. A. Command line injection
2. B. Brute-force attacks
3. C. Cross-site attacks
4. D. Remote code execution

Correct Answer: ABCD
Common Attack Methods in Enterprise Networks:
Enterprise networks are vulnerable to various cyberattacks, targeting both infrastructure and applications.
Explanation of Each Attack Method:
Command line injection:Exploits vulnerabilities in command-line interfaces to execute unauthorized commands.
Brute-force attacks:Attempts to guess passwords or encryption keys through exhaustive trial-and-error methods.
Cross-site attacks:Includes cross-site scripting (XSS) and cross-site request forgery (CSRF), targeting web applications.
Remote code execution:Exploits vulnerabilities to execute arbitrary code on a target system, often leading to full system compromise.
Conclusion:All four options represent common attack methods faced by enterprise networks.
