NEW QUESTION # 46
If only one firewall is deployed at the egress of the network, a failure on the firewall will affect services on the entire network. To improve network reliability, you can deploy two or more firewalls and set up a stack system. Member firewalls do not need to be managed independently. You only need to configure the stack system.

• A. False
• B. True

Answer: B

Explanation:
In Huawei firewall deployments (such as USG6000 series), using a single firewall at the network egress creates a single point of failure (SPOF).
To improve reliability, Huawei supports firewall stacking technology, called FW-Stack.
In a firewall stack, multiple firewalls form a single logical device.
Advantages of firewall stacking include:
Unified management: Only the stack system is configured and managed, not individual members.
Seamless failover: If a member firewall fails, services continue on other members.
Increased throughput: Aggregate performance of multiple firewalls.
This setup greatly enhances service continuity and improves network reliability without needing complex configuration across devices.

NEW QUESTION # 52
The free mobility solution allows a user on a campus network to obtain the same network access policy regardless of the user's location and IP address. When configuring a policy, the administrator does not need to pay attention to the IP address ranges of different users, but only needs to focus on the logical access relationships between users and servers.

• A. False
• B. True

Answer: B

Explanation:
Huawei's Free Mobility Solution decouples user identity from IP address and physical location.
Regardless of where a user accesses the campus network (wired or wireless), the same network access policies (such as ACLs, QoS, VLAN assignments) are dynamically applied based on the user identity.
Administrators only need to define access policies between user groups and server resources based on logical relationships (e.g., HR can access payroll servers) without worrying about IP addressing or user location.
This mechanism uses technologies like VXLAN-based campus network combined with policy association via iMaster NCE-Campus.

NEW QUESTION # 57
A higher antenna gain indicates stronger signals and wider coverage. Therefore, an AP with a higher antenna gain is preferred in allowed countries.

• A. True
• B. False

Answer: B

Explanation:
A higher antenna gain indicates a narrower beamwidth and greater signal directivity-not necessarily wider coverage. While high-gain antennas can transmit stronger signals in a specific direction, they reduce coverage in other directions. In WLAN design, especially for omnidirectional coverage in campus scenarios, antenna selection is based on application requirements rather than simply preferring higher gain.
Huawei emphasizes that antenna gain must comply with local regulations and should match deployment scenarios (e.g., indoor omnidirectional vs outdoor long-range). Excessively high gain may result in coverage holes or regulatory non-compliance.
