問題 #94
When a host uses the stateless address autoconfiguration solution to obtain an IPv6 address, the host cannot obtain the DNS server address.
答案：B
解題說明：
Stateless Address Autoconfiguration (SLAAC) allows IPv6 hosts to generate their own IP addresses but does not include DNS server information. DHCPv6 is typically required for DNS configuration.
問題 #95
Drag and Drop Question
On a general-purpose computing data center network, network administrators need to use various network technologies or architectures to ensure high network stability and efficiency.
Match the following network technologies or architectures with the requirements they meet.
答案：
解題說明：
Explanation:
M-LAG → High availability
Spine-Leaf → Scalability
VXLAN → User isolation
M-LAG provides device-level and link-level redundancy, ensuring services continue running even if a link or device fails, which directly improves high availability. Spine-Leaf is a scalable data center architecture designed to allow easy horizontal expansion with predictable performance as the network grows. VXLAN enables network virtualization by isolating tenant networks over a shared physical infrastructure, supporting strong user or tenant isolation.
問題 #96
Which of the following fields are included in an MPLS header?
答案：B,C,D
解題說明：
An MPLS (Multiprotocol Label Switching) header includes the following fields:
Label: Identifies the MPLS path.
TTL (Time to Live): Limits the lifetime of the MPLS packet.
EXP (Experimental): Used for QoS marking. The Tos (Type of Service) field is part of the IP header, not MPLS.
問題 #97
Huawei network devices support multiple types of storage devices. After the administrator enters the save command in the user view of a switch, the current configuration file is saved to the SDRAM. After the switch restarts, the configuration file still takes effect.
答案：A
解題說明：
On Huawei switches, the active configuration is stored in SDRAM during operation, but SDRAM is volatile memory. The save command writes the configuration to non-volatile storage (such as NVRAM/flash), not to SDRAM. This is what allows the configuration to persist after a restart.
問題 #98
When configuring wireless services on a Huawei WAC, you need to configure a service VLAN to ensure the proper transmission of data packets from STAs. In which of the following profiles is the service VLAN configured?
答案：C
解題說明：
On a Huawei WAC, the VAP profile is the profile that brings together the service attributes required to instantiate a wireless service on an AP radio. The service VLAN is configured in this VAP profile using the service-vlan command. The VAP profile can also reference an SSID profile and a security profile and can define the data forwarding mode, allowing the wireless service to map associated STA traffic into the correct wired VLAN. The SSID profile primarily defines the WLAN name and related SSID behavior. The security profile defines authentication and encryption policies such as WPA/WPA2/WPA3 parameters. The regulatory domain profile controls radio regulatory settings such as country-specific channel and transmit-power constraints. None of those profiles is the location in which the service VLAN itself is defined. Huawei configuration examples explicitly show the administrator entering the VAP profile view and then applying service-vlan vlan-id or a VLAN pool. Therefore, the correct choice is C, VAP profile.
