質問 # 13
In an 802.1X-based subscriber authentication design, which role does the residential gateway normally perform?
正解：B
解説：
The residential gateway normally acts as the 802.1X supplicant. It supplies identity information and participates in the Extensible Authentication Protocol exchange required to obtain network access. The access device or OLT commonly performs the authenticator role, controlling the subscriber-facing port and relaying authentication information between the supplicant and the authentication server. The authentication server, frequently using RADIUS, validates the credentials and returns an authorization result or related policy attributes. The gateway is therefore not itself the RADIUS database or authentication server in this design. A multicast querier performs a separate function by sending IGMP queries to maintain multicast membership information. Before successful authentication, the authenticator generally restricts ordinary subscriber traffic while allowing the authentication exchange required to complete access control.
質問 # 14
Which transport protocol is commonly used to provide a secure connection for NETCONF sessions?
正解：D
解説：
NETCONF is commonly transported over Secure Shell, which provides encryption, integrity protection, and peer authentication for the management session. After establishing the secure transport connection, the client and server exchange NETCONF capabilities and use RPC messages to retrieve or modify device data. IGMP manages IPv4 multicast group membership and does not provide a secure management transport. ARP resolves IPv4 addresses to Layer 2 hardware addresses within a local network. SIP establishes and manages communication sessions such as voice calls. Although NETCONF can conceptually operate over supported secure transports, NETCONF over SSH is the widely recognized deployment model. Secure transport is particularly important because NETCONF can expose operational information and perform configuration changes that materially affect access-network devices and subscriber services.
質問 # 15
In an IPFIX deployment, which component observes traffic and sends flow records to a receiving system?
正解：A
解説：
An IPFIX exporting process observes traffic at an observation point, creates flow records, and sends those records to an IPFIX collecting process. Templates describe the fields contained in the exported records, allowing the collector to interpret information such as source and destination addresses, transport ports, protocol identifiers, counters, and timestamps. The collector can store and analyze these records for traffic visibility, capacity planning, troubleshooting, accounting, or security analysis. IPFIX does not permanently store all collected information on the exporting network device. A passive optical splitter cannot inspect or export traffic because it has no active processing functions. An 802.1X supplicant participates in access authentication, while a SIP registrar maintains information used to locate SIP users or endpoints.
質問 # 16
How does an ADSL connection support simultaneous traditional voice and broadband data over the same copper pair?
正解：B
解説：
ADSL uses frequency-division techniques to place traditional analog voice and broadband data in different portions of the available copper-pair spectrum. The lower-frequency range is reserved for voice, while higher-frequency ranges carry upstream and downstream DSL data. Filters or splitters separate these frequency ranges at the subscriber and network sides, allowing a telephone call and an Internet session to operate simultaneously. The services are not required to alternate in time, and an optical wavelength is not involved because ADSL operates over copper. GPON time-slot scheduling applies to upstream transmissions from ONTs on a passive optical network, not to ADSL voice separation. Line quality, loop length, attenuation, and interference affect the data rate that ADSL can achieve.
質問 # 17
Which architectural principle is fundamental to Software-Defined Networking?
正解：B
解説：
A central principle of Software-Defined Networking is the separation of control logic from packet-forwarding functions. The data plane remains responsible for forwarding traffic, while logically centralized control software determines policies and programs network behavior through defined interfaces. Logically centralized does not necessarily mean that all controller functions run on one physical server; they may be distributed for scalability and resilience while presenting a coordinated control view. SDN emphasizes programmability, automation, abstraction, and the use of APIs. It does not require every forwarding device to independently make all high-level policy decisions. It also avoids tightly coupling every function into one fixed proprietary system. In fixed-access networks, these concepts help operators automate service delivery and manage different access devices through common models and controller applications.
