NEW QUESTION # 33
Which Altiplano intent is used to define the uplink interfaces that connect an OLT toward the aggregation network?
Answer: A
NEW QUESTION # 34
What does hardware abstraction provide in a disaggregated access network?
Answer: D
Explanation:
Hardware abstraction separates higher-level control and management functions from many platform-specific implementation details. It can provide controllers and applications with consistent models or interfaces for operating different supported hardware platforms. This makes automation, service development, and multivendor management more practical because applications do not need to reproduce every low-level procedure for each device. Abstraction does not require all platforms to contain identical components, nor does it eliminate actual differences in capacity, features, or operational constraints. Those differences must still be represented where relevant. It also does not make active access equipment passive. In a disaggregated access architecture, software is divided into functional modules, and standardized or well-defined interfaces allow those modules to interact with abstracted device resources and with higher-level orchestration or assurance applications.
NEW QUESTION # 35
Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?
Answer: A
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.
NEW QUESTION # 36
Which traffic-delivery method is commonly used for a live IPTV channel watched simultaneously by many subscribers?
Answer: C
Explanation:
Live IPTV channels are commonly distributed using multicast because many subscribers may request the same content at the same time. The network carries a shared stream across common paths and replicates packets only where delivery paths branch toward participating receivers. Subscribers signal membership using protocols such as IGMP. This approach is more bandwidth-efficient than delivering a separate unicast copy from the source to every viewer. Video on Demand is commonly delivered using unicast because each viewer may start, pause, or seek through different content independently. NETCONF notifications carry management events rather than television content. IPTV is packet-based and does not require a separate analog transmission for every copper pair. Effective multicast deployment also depends on correct group control, snooping, routing, QoS, and service-forwarding configuration.
NEW QUESTION # 37
Why must a managed ONT or residential gateway be reachable before an Auto Configuration Server can provision it using TR-069?
Answer: D
Explanation:
TR-069 enables remote management through communication between customer-premises equipment and an Auto Configuration Server. The device must be powered, operational, and able to establish or participate in a management session before configuration parameters, software information, diagnostics, or status data can be exchanged. An ACS cannot provision a device that is completely offline because no active communication path exists. TR-069 does not configure passive splitters, which contain no management processor or configurable service logic. The managed device can be located at the subscriber premises and does not need to be inside the central office. Communication is carried over the device's network connection rather than exclusively through an OLT serial console. Authentication and protected transport help secure management exchanges between the device and the ACS.
