NEW QUESTION # 36
Which transport protocol is commonly used to provide a secure connection for NETCONF sessions?
Answer: C
Explanation:
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.
NEW QUESTION # 37
How does an ADSL connection support simultaneous traditional voice and broadband data over the same copper pair?
Answer: A
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 # 38
A QoS policy examines a packet's markings and assigns it to a forwarding class. Which QoS function is being performed?
Answer: D
Explanation:
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.
NEW QUESTION # 39
What does hardware abstraction provide in a disaggregated access network?
Answer: A
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.
