NEW QUESTION # 10
How does an ADSL connection support simultaneous traditional voice and broadband data over the same copper pair?
Answer: D
Explanation:
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.
NEW QUESTION # 11
In an 802.1X-based subscriber authentication design, which role does the residential gateway normally perform?
Answer: B
Explanation:
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.
NEW QUESTION # 12
What is a key characteristic of software disaggregation in an access network?
Answer: B
Explanation:
Software disaggregation separates access-network software into modules, with each module responsible for a particular functional area. Defined interfaces allow these modules to interact with one another, with higher-level applications, and with abstracted hardware resources. This architecture can improve development flexibility, automation, scalability, and the ability to introduce new functions without replacing an entire vertically integrated platform. It does not mean that all physical constraints disappear or that every module can operate on every device without adaptation. Embedding every function permanently in one appliance describes a tightly integrated architecture rather than disaggregation. APIs are important because they enable communication and programmability between components. Passive optical splitters cannot execute software because they contain no powered processing or control functions.
NEW QUESTION # 13
What is a typical function of the Network Termination card in a Nokia Lightspan access node?
Answer: B
Explanation:
The Network Termination card provides network-facing connectivity for a Lightspan access node. Its faceplate can contain connectors and optical cages used to connect the node to external aggregation, transport, management, synchronization, or other supported interfaces. The card participates in forwarding traffic between subscriber-facing line termination resources and the upstream network. It is an active component and must not be confused with a passive optical splitter in the outside plant. It also does not provide in-home Wi-Fi directly to subscriber devices; that function belongs to a residential gateway or Wi-Fi access point. Analog telephones are normally connected through voice-capable subscriber equipment, such as an ONT with appropriate telephone interfaces, rather than directly to the Lightspan NT card.
NEW QUESTION # 14
Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?
Answer: B
Explanation:
A passive optical splitter divides an incoming optical signal into multiple output paths without requiring electrical power. It is a fundamental component of the Optical Distribution Network connecting an OLT to multiple ONTs or ONUs. The splitter does not regenerate, amplify, or actively switch the optical signal. Consequently, splitting introduces optical loss that must be considered when calculating the PON power budget. The OLT and ONT are active devices because they require power to transmit, receive, process, and convert signals. A residential gateway also requires power to provide functions such as routing, firewall enforcement, DHCP, Ethernet switching, and Wi-Fi connectivity. The use of passive splitters reduces the need for powered equipment in the outside plant, which can simplify field maintenance and lower operational costs.
