問題 #61
iMaster NCE-Campus can implement refined policy control over user permissions. Which of the following can be used as policy conditions?
答案：A,B,C,D
解題說明：
All four options can be used as conditions by the iMaster NCE-Campus intelligent policy engine. Huawei describes this capability through a 5W1H-based policy model. "Who" represents the user identity, user group, or role. "Where" represents the access location, including the site, region, device group, device, SSID, or IP address. "How" represents the access mode, such as wired or wireless access and the authentication method used. "What" represents the terminal type or device attributes, including PCs and mobile operating systems.
The platform can combine these conditions rather than evaluating them independently. For example, a finance employee using a corporate laptop through wired 802.1X access at headquarters can receive different permissions from the same employee connecting through a personal mobile device at a branch. The authorization result can include a VLAN, ACL, security group, bandwidth limit, DSCP value, application policy, or URL-filtering rule.
This multidimensional evaluation enables context-aware, fine-grained access control. Therefore, A, B, C, and D are all correct.
問題 #62
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?
答案：D
解題說明：
A central switch in the relevant passive Ethernet network architecture supports a maximum of 48 access units.
The architecture replaces a conventional multi-layer access design with a centralized switch and distributed remote or access units. The access units function as extensions of the central switch's ports, simplifying device management, configuration, and topology maintenance.
Huawei's CloudEngine S5731-H fixed central-switch specification provides models with 24 or 48 hybrid optical-electrical downlink ports. The 48-port model can therefore directly manage up to 48 associated access or remote units under the design limits represented by this question. The same hybrid links can provide data transmission and remote PoE power, enabling access units to be installed closer to terminals without requiring conventional active aggregation equipment at every location.
The central switch automatically discovers the topology, while remote units behave as extended ports rather than independently managed switches. This reduces management nodes and simplifies a traditional three- layer network into a two-layer architecture. The larger values of 64, 72, and 96 exceed the supported maximum for the specified central-switch implementation. Therefore, option C is correct.
問題 #63
What is the function of the PROFINET DCP?
答案：D
解題說明：
PROFINET DCP, meaning Discovery and Basic Configuration Protocol, is used during device discovery and initial network configuration. It operates at the data-link layer and enables an engineering station or PROFINET IO controller to locate devices on the local Ethernet segment, identify them by MAC address or station name, assign a PROFINET device name, and configure IP parameters such as the IP address, subnet mask, and default gateway.
DCP is therefore not responsible for normal cyclic process-data exchange. Real-time PROFINET communication performs that function after the controller and I/O device have been configured and an application relationship has been established. Alarm exchange and acyclic parameterization are also handled through other PROFINET communication relationships and services.
The distinction matters during commissioning. A new I/O device may initially have no usable IP configuration. DCP allows the controller or engineering tool to discover it at Layer 2 and provision the identity and addressing information required before higher-layer communication can begin. PROFINET documentation identifies DCP as mandatory for assigning IP addresses and configuring station names on the local network.
問題 #64
Which of the following BGP NLRI address-family combinations is used to transmit SD-WAN tunnel encapsulation information?
答案：B
解題說明：
AFI 1 with SAFI 74 is the correct combination. In Multiprotocol BGP, the Address Family Identifier defines the basic network-layer address family, while the Subsequent Address Family Identifier specifies how the associated NLRI is interpreted. AFI 1 represents IPv4. SAFI 74 is assigned for SD-WAN capabilities and is used to distribute information required for SD-WAN edge discovery and tunnel establishment, including transport and encapsulation-related attributes.
The other combinations represent different forms of reachability information. AFI 1/SAFI 1 is ordinary IPv4 unicast NLRI. AFI 1/SAFI 2 represents IPv4 multicast reachability. AFI 25 represents Layer 2 VPN information, while SAFI 70 represents Ethernet VPN routes; that combination is associated with EVPN rather than the specific SD-WAN capability NLRI requested.
Huawei's architecture uses BGP-based control channels to exchange transport network port information, IPsec security-association information, and service routes. These parameters allow edge devices to determine peer endpoints and create GRE or GRE-over-IPsec data channels after the relevant service routes trigger tunnel establishment.
問題 #65
What are the two IPsec data encapsulation modes?
答案：A,D
解題說明：
The two IPsec encapsulation modes are transport mode and tunnel mode. In transport mode, IPsec protects the upper-layer payload of the original IP packet while retaining the original IP header as the packet's outer header. It is commonly associated with end-to-end host communication, although it can also protect a GRE packet between tunnel endpoints.
In tunnel mode, IPsec protects the complete original IP packet and adds a new outer IP header containing the addresses of the IPsec peers. This mode is commonly used between security gateways, routers, or site-to-site VPN endpoints because the original source and destination information can be protected within the encrypted inner packet. RFC 4301 formally defines transport and tunnel as the two IPsec security-association modes.
AH and ESP are not encapsulation modes. They are IPsec security protocols. Authentication Header provides integrity and source authentication but not encryption. Encapsulating Security Payload can provide encryption, integrity, authentication, and anti-replay protection. Either protocol can conceptually operate in transport or tunnel mode, although ESP is overwhelmingly used for encrypted enterprise VPN and SD-WAN data channels.
