NEW QUESTION # 14
A subscriber installs several coordinated Wi-Fi access points to provide consistent coverage throughout a large home. What type of solution is this?
Answer: B
Explanation:
A Wi-Fi mesh system uses multiple coordinated Wi-Fi nodes or access points to extend wireless coverage across a home or other large area. The nodes operate as part of one managed system and can steer clients or select paths to improve coverage and user experience. This differs from a single Wi-Fi router, which combines routing, switching, and wireless access functions in one device but may not adequately cover a large property. A passive optical network delivers fiber access and does not describe the in-home wireless topology. DSL bonding combines copper pairs, while a virtual network function is a software implementation of a network function running on virtualized infrastructure. Placement, backhaul quality, interference, and radio-resource management all affect mesh performance.
NEW QUESTION # 15
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 # 16
A service provider combines two copper pairs to increase the available DSL rate for one subscriber. Which technology is being used?
Answer: A
Explanation:
DSL bonding combines two or more physical copper pairs into a single logical subscriber connection. Traffic is distributed across the available pairs, allowing the aggregate bitrate to increase, provided the individual lines have suitable quality and compatible performance. Bonding can also provide operational benefits where one pair alone cannot deliver the required service rate. It is different from vectoring, which reduces crosstalk among coordinated copper lines by generating compensating signals. Optical splitting divides optical power in a PON and does not combine copper capacity. Multicast replication creates copies of multicast packets for different receiver paths and is unrelated to DSL transmission capacity. Both ends of a bonded DSL connection must support the applicable bonding method and coordinate traffic across the paired lines.
NEW QUESTION # 17
In intent-based networking, what does an operator primarily specify through an intent?
Answer: B
Explanation:
An intent describes the desired network outcome or target state rather than requiring the operator to manually enter every device-level command. The intent system maps the requested outcome to the configurations and resources needed on the relevant network elements. It can then compare the intended state with the observed operational state and take corrective action when supported. Intent types, profiles, and associated models provide the logic and parameters required for this translation. An intent does not normally specify the electrical construction of hardware or list every packet to be forwarded. Optical measurements may be used as operational inputs, but they are not the general definition of an intent. This abstraction improves consistency, supports automation, and reduces repetitive device-by-device configuration work.
NEW QUESTION # 18
What is a principal responsibility of the NFV Orchestrator in an NFV environment?
Answer: A
Explanation:
The NFV Orchestrator coordinates the lifecycle of network services composed of one or more virtualized network functions and helps coordinate the infrastructure resources required by those services. It can work with Virtual Network Functions Managers and Virtualized Infrastructure Managers during service instantiation, scaling, modification, and termination. The VNFM focuses on the lifecycle of VNF instances, while the VIM manages virtualized compute, storage, and networking resources. The NFV Orchestrator does not terminate GPON optical signals, manage individual home Wi-Fi radio channels as its primary function, or perform physical fiber installation. Its higher-level coordination role helps translate a network-service definition into the deployment and resource actions necessary to create and maintain that service within the virtualized environment.
