NPTEL Edge Computing Week 1 Assignment Solution

Why does MEC significantly improve Quality of Experience (QoE) for real-time applications?

  • A) It increases bandwidth availability
  • B) It reduces packet loss using redundancy
  • C) It shifts computation entirely to the cloud
  • D) It minimizes end-to-end latency by local processing
The correct answer is D.
Explanation: MEC places computation closer to users, significantly reducing latency, which is critical for real-time applications.

Which deployment location best supports MEC’s objective of ultra-low latency?

  • A) Centralized hyperscale cloud
  • B) User equipment only
  • C) Base stations or aggregation points
  • D) Internet backbone routers
The correct answer is C.
Explanation: Deploying MEC at base stations or aggregation points minimizes network hops and latency.

Which feature of SDN makes it suitable for supporting large-scale edge services?

  • A) Centralized traffic engineering and global view
  • B) Hardware-defined routing
  • C) Distributed control planes
  • D) Static routing policies
The correct answer is A.
Explanation: SDN’s centralized control and global network visibility enable efficient traffic management for edge services.

Why does the distributed nature of edge computing increase its attack surface?

  • A) Edge nodes use outdated protocols
  • B) Edge nodes store sensitive data permanently
  • C) Edge nodes are geographically dispersed and physically exposed
  • D) Edge systems disable encryption
The correct answer is C.
Explanation: Widely distributed and physically accessible edge nodes are more vulnerable to attacks.

A smart surveillance camera performs real-time object detection. Local processing drains battery quickly, but a nearby MEC server is lightly loaded. What is the MOST suitable decision?

  • A) Execute fully on the cloud
  • B) Execute fully on the device
  • C) Delay processing until batch mode
  • D) Offload computation to the MEC server
The correct answer is D.
Explanation: Offloading to a nearby MEC server balances energy efficiency and low latency.

A global gaming platform wants fast response times for users in Asia and Europe while complying with regional data laws. Which architecture best satisfies this requirement?

  • A) Single centralized cloud
  • B) Geo-distributed edge-cloud architecture
  • C) Edge-only deployment
  • D) Local device processing
The correct answer is B.
Explanation: A geo-distributed edge-cloud setup ensures low latency and regulatory compliance.

Which factor MOST differentiates MEC from fog computing?

  • A) Standardized integration with cellular networks
  • B) Use of distributed nodes
  • C) Use of virtualization
  • D) Use of cloudlets
The correct answer is A.
Explanation: MEC is tightly standardized and integrated with cellular networks, unlike fog computing.

Which cloud service model provides users with virtualized computing resources such as virtual machines, storage, and networking, while allowing full control over the operating system?

  • A) Software as a Service (SaaS)
  • B) Platform as a Service (PaaS)
  • C) Infrastructure as a Service (IaaS)
  • D) Function as a Service (FaaS)
The correct answer is C.
Explanation: IaaS offers virtualized infrastructure with full OS-level control to users.

A company wants to deploy applications without managing servers or operating systems, while still controlling application logic and data. Which cloud service model best fits this requirement?

  • A) Infrastructure as a Service (IaaS)
  • B) Private Cloud
  • C) Software as a Service (SaaS)
  • D) Platform as a Service (PaaS)
The correct answer is D.
Explanation: PaaS abstracts infrastructure while allowing developers to manage application logic and data.

Micro edge computing refers to computing performed at intelligent sensors or end devices. Which statement correctly describes micro edge devices?

  • A) They are high-performance servers deployed in data centers
  • B) They are cloud-managed virtual machines with unlimited resources
  • C) They consist of data-generating sensors or devices with low-end processors and minimal distance to computation
  • D) They are intermediate nodes between edge and cloud
The correct answer is C.
Explanation: Micro edge devices are resource-constrained sensors or end devices performing computation very close to data generation.
