Nokia Fixed Networks Fundamentals 4A0-F10 Prüfungsfragen mit Lösungen (Q33-Q38):

33. Frage
In an IPFIX deployment, which component observes traffic and sends flow records to a receiving system?

A. Passive optical splitter
B. Exporting process
C. SIP registrar
D. 802.1X supplicant

Antwort: B

Begründung:
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.

34. Frage
Which YANG node type represents multiple scalar values under the same node name without allowing child nodes?

A. Container
B. List
C. Choice
D. Leaf-list

Antwort: D

Begründung:
A YANG leaf-list represents a sequence of scalar values of the same defined type. Like a leaf, each value is terminal and cannot contain child nodes. However, unlike a single leaf, a leaf-list can have multiple entries. A YANG list also supports multiple instances, but each list entry can contain child nodes and is normally identified by one or more key leaves. A container groups related child nodes but does not itself represent a repeated collection of scalar values. A choice defines alternative branches in a data model, allowing one set of nodes from the available cases to be selected. Correctly distinguishing these node types is important when interpreting YANG schemas used to configure and monitor access devices through model-driven management interfaces.

35. Frage
Which characteristic distinguishes G.fast from traditional ADSL technologies?

A. G.fast operates only over passive optical splitters.
B. fast is designed to deliver high broadband rates over relatively short copper loops, frequently using existing building or drop wiring. It uses a much wider and higher-frequency spectrum than traditional ADSL and commonly employs Time Division Duplexing. With TDD, upstream and downstream transmission use the same frequency spectrum during different time intervals. The upstream-to-downstream capacity ratio can therefore be adjusted through the TDD configuration. Higher frequencies can support greater capacity but experience substantial attenuation over distance, which is why G.fast is best suited to short loops. It does not operate through passive optical splitters, although fiber may be deployed close to the subscriber before the final copper segment. G.fast also supports broadband services rather than voice-only delivery.
C. G.fast carries only voice services and does not support broadband data.
D. G.fast commonly uses high frequencies and time-division duplexing over short copper loops.
E. G.fast requires a separate copper pair for upstream and downstream traffic.

Antwort: D

36. Frage
In an 802.1X-based subscriber authentication design, which role does the residential gateway normally perform?

A. Supplicant
B. Authentication server
C. Multicast querier
D. RADIUS database

Antwort: A

Begründung:
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.

37. Frage
A QoS policy examines a packet's markings and assigns it to a forwarding class. Which QoS function is being performed?

A. Optical amplification
B. Shaping
C. Classification
D. Policing

Antwort: C

Begründung:
Classification examines packet information and determines how the packet should be treated by the QoS system. The decision can use fields such as VLAN priority, Differentiated Services Code Point, protocol information, or interface context. After classification, the packet is assigned to an appropriate forwarding class and queue so that scheduling, congestion management, and other policies can provide the intended treatment. Shaping controls an outgoing rate by buffering excess traffic, while policing enforces a traffic profile by dropping or remarking nonconforming packets. Optical amplification increases optical signal power and is unrelated to packet classification. Effective classification is essential when a fixed-access network carries services with different requirements, such as voice, IPTV, management traffic, and best-effort Internet access.
