Answer: A

3. Layer 2 switching is one of the most common Ethernet technologies. Which of the following statements is false about Layer 2 switching principles?

A. Layer 2 switch maintains a MAC address-to-interface mapping table-known as the MAC address table - by parsing and learning source MAC addresses of Ethernet frames. When receiving an Ethernet frame, the switch searches its MAC address table for the outbound interface based on the destination MAC address of the frame.

B. If the destination MAC address of a received data frame is not a broadcast address, the switch searches the MAC address table for a matching entry based on the destination MAC address of the frame. If a matching entry is found, the switch forwards the frame to the corresponding interface. If no matching entry is found, the switch discards the frame.

C. Layer 2 switch works at the second layer (data link layer) of the OSI model and forwards data packets based on MAC addresses.

D. If the destination MAC address of a received frame is a broadcast address, the switch forwards the frame to all interfaces (except the inbound interface of the frame) in the same VLAN.

Answer: B

4. Which of the following technologies is used to connect one device to another two devices through inter-device link aggregation to improve link reliability from the card level to the device level and form an active-active system?

A. M-LAG

B. CSS

C. iStack

D. VRRP

Answer: A

5. It supports unified management of various security devices, including firewalls, IPS devices, and anti-DDoS devices, and allows automatic deployment of security services as well as centralized management of network-wide security policies. Which of the following is it?

A. USG

B. SecoManager

C. eSight 

D. iMaster NCE

Answer: B

6. Which of the following statements is false about the technologies used on an IP WAN transport network?

A. FlexE interfaces can be completely isolated from each other. Specifically, traffic is isolated at the physical layer, and network slicing is performed for services on the same physical network.

B. SRv6 is a protocol designed to forward IPv6 data packets on a network using the source routing model. SRv6 deployment depends on MPLS networks.

C. IFIT integrates coloring and in-band flow measurement technologies to directly measure service packets. It works with telemetry and NCE to implement real-time visualization of network quality and traffic SLA, proactive monitoring, as well as fast fault demarcation and locating.

D. MACsec protects transmitted Ethernet data frames to reduce information leakage and mitigate malicious network attacks.

Answer: B

7. Which of the following statements is false about telemetry?

A. Telemetry is a technology that remotely collects data from physical or virtual devices at a high speed.

B. Huawei CloudCampus Intelligent O&M Solution uses the telemetry technology to collect network device KPIs, implementing collection of user experience indicators within seconds.

C. Similar to SNMP, telemetry uses the quick Q&A mechanism between the management and analysis system and devices, allowing the management and analysis system to obtain network data in real time for intelligent analysis.

D. Telemetry packs the data to be sent, improving transmission efficiency.

Answer: C

8. A security zone (zone for short) is a security concept introduced by a device. Most security policies are implemented based on security zones. Which of the following statements are true about security zones?

A. All interfaces of a firewall are added to the Trust zone by default.

B. Each security zone has a security level, which is also called priority. The priority value ranges from 1 to 100. A larger value indicates a higher security level

C. The following security zones are preconfigured in the system by default: Trust, DMZ, and Untrust.

D. Users can also customize new security zones as required.

12. Huawei's SmartRadio technology supports software-defined radio (SDR). Which of the following are the benefits of this technology?

A. In high-bandwidth scenarios, the dual-radio mode is used to provide ultra-high throughput.

B. In high-concurrency scenarios, the triple-radio mode is used to allow more STAs to access the network concurrently.

C. In scenarios with severe interference, the dual-radio + independent scanning radio mode is used. In this mode, the independent radio is used to monitor and optimize the network quality in real time without compromising network performance.

D. On a large-scale network, APs working in different radio modes can be deployed together, meeting requirements of different services and traffic types, improving network-wide performance, and saving the TCO.

Answer: ABCD

13. Which of the following are typical application scenarios of the stacking technology?

A. Improved reliability: Member switches in a stack work in redundancy mode.

B. Increased number of ports: If the port density of the original switch cannot meet the access requirements of users, you can add new switches to set up a stack with the original one to increase the number of ports.

C. Increased bandwidth: When higher uplink bandwidth is required, you can add new switches to set up a stack with the original one, and bundle physical links of the member switches into a link aggregation group to increase the uplink bandwidth.

D. Simplified networking: Multiple devices set up a stack and are virtualized into a single logical device. The simplified networking does not require loop prevention protocols, such as MSTP, making network configuration much simpler. In addition, the use of inter-device link aggregation achieves fast convergence upon the failure of a single device, improving reliability.

Answer: ABCD

14. VLAN is an important basic technology on campus networks. Which of the following benefits does VLAN bring to users?

A. Limited broadcast domains: Broadcast domains are limited to a single VLAN, conserving bandwidth and improving network efficiency.

B. Service isolation: Layer 2 and Layer 3 communication between different VLANs is completely isolated, and users in different VLANs cannot communicate with each other.

C. Allows for flexible virtual groups: VLAN technology allows hosts to be divided into different groups, and hosts in different geographical locations can be grouped together, simplifying network construction and maintenance.

D. Enhances LAN security: Packets from different VLANs are separately transmitted, so that hosts in a VLAN cannot directly communicate with those in another VLAN.
