Which of the following is a primary characteristic of Mobile Ad Hoc Networks (MANETs)?
A Fixed infrastructure
B Centralized control
C Dynamic topology
D High latency
MANETs are decentralized networks where devices can join or leave at any time. Their topology changes dynamically as devices move, making them highly flexible but also challenging to manage due to constantly changing connections.
Which of the following is a key feature of Delay Tolerant Networking (DTN) in challenging network environments?
A Store and forward communication
B High speed data transfer
C Continuous connectivity
D Low power consumption
Delay Tolerant Networking (DTN) is designed to handle networks where continuous connectivity is not guaranteed. It uses store and forward techniques, allowing data to be stored temporarily and forwarded when a connection is available.
Which technology is commonly used in Edge Computing to process data closer to the source of the data generation?
A Cloud computing
B IoT
C Distributed computing
D Fog computing
Fog computing extends cloud computing capabilities to the edge of the network. It processes data closer to the source, reducing latency, conserving bandwidth, and enabling faster decision making for time sensitive applications.
Which of the following is a challenge in Mobile Ad Hoc Networks (MANETs) related to network communication?
A Static routing
B Scalability
C Continuous availability
D Stable topology
MANETs often struggle with scalability due to their dynamic nature. As the number of devices increases, managing communication and ensuring efficient routing becomes more difficult, requiring dynamic, adaptive protocols to maintain network performance.
In Delay Tolerant Networks (DTNs), what happens when there is no immediate route between source and destination?
A Data is discarded
B Data is compressed
C Data is stored for later forwarding
D Data is sent to a proxy
In DTNs, when no direct route exists between source and destination, the data is stored temporarily. It is forwarded later when a route becomes available, enabling communication in environments with intermittent connectivity.
Which of the following best describes the role of Edge Computing in modern networks?
A Reducing the distance between data generation and processing
B Centralizing data processing
C Providing remote storage
D Ensuring cloud data security
Edge computing brings data processing closer to the devices or sensors that generate the data, reducing latency and bandwidth use. This is especially beneficial for applications requiring real time or near real time responses.
Which of the following is a primary benefit of using Fog Computing in IoT applications?
A Improved data security
B Increased cloud storage
C Reduced data processing time
D Higher power consumption
Fog computing processes data closer to the source, reducing the need to send large amounts of data to centralized clouds. This decreases data transmission time and latency, which is essential for time sensitive IoT applications.
What is the main advantage of using MANETs in military or emergency operations?
A Centralized control
B Stable connections
C High speed internet access
D Flexible and dynamic networks
MANETs are ideal for military or emergency operations because they can be rapidly deployed in any environment without needing a fixed infrastructure. Their ability to form dynamic, self organizing networks makes them highly flexible.
Which of the following is a major challenge that Delay Tolerant Networking (DTN) seeks to address?
A Real time communication
B Network security
C Intermittent connectivity
D High bandwidth
DTN is specifically designed for networks where there is intermittent or disrupted connectivity. It allows communication in environments such as remote areas or space, where continuous end to end paths are not available.
Which of the following is a key difference between Edge Computing and Cloud Computing?
A Cloud computing processes data at the device
B Edge computing processes data locally
C Edge computing has higher latency
D Edge computing processes data centrally
Edge computing processes data closer to the data source, such as on local devices or nearby servers, reducing latency and bandwidth usage. Cloud computing, on the other hand, centralizes processing in remote data centers.
In Mobile Ad Hoc Networks (MANETs), which protocol is commonly used for routing data in the absence of a fixed infrastructure?
A AODV
B OSPF
C RIP
D BGP
AODV (Ad hoc On Demand Distance Vector) is a routing protocol specifically designed for MANETs. It enables nodes to dynamically discover routes for data transmission, adapting to network changes caused by node mobility.
Which of the following is an advantage of using Delay Tolerant Networking (DTN) in satellite communication?
A Real time data transmission
B Improved routing efficiency
C Lower power consumption
D Seamless data flow during network disruptions
DTN enables satellite communication systems to function effectively during network disruptions by storing data temporarily and forwarding it when a suitable connection becomes available. This ensures that data is not lost in intermittent connections.
In IoT networking, what is the role of Edge Computing in handling data from sensors and devices?
A Offload heavy computations to the cloud
B Process data on centralized servers
C Process data closer to the source
D Encrypt data for security
Edge Computing processes data at or near the source, such as on IoT devices or local servers. This reduces the amount of data transmitted to the cloud, minimizing latency and improving response times in IoT applications.
What is the main benefit of using MANETs in autonomous vehicle networks?
A Ability to adapt to changing environments
B Real time traffic monitoring
C Increased infrastructure complexity
D Fixed network paths
MANETs allow autonomous vehicles to communicate directly with each other, creating dynamic networks that can adapt to changes in the environment. This is crucial for navigating unpredictable road conditions and traffic situations.
Which of the following technologies is most suitable for applications requiring minimal latency and real time data processing?
A Delay Tolerant Networking
B Fog computing
C Cloud computing
D MANETs
Fog computing is ideal for real time data processing as it processes data closer to the source of data generation. This reduces latency and is beneficial for applications like autonomous vehicles, smart grids, and industrial automation.
