IoT-optimized GSM network, deployed with software upgrade
RATIONALE
An IoT-optimized GSM network enhances connectivity by supporting a higher density of devices and improved data throughput, critical for
extended coverage in IoT applications. Software upgrades enable the network to utilize advanced protocols and features, optimizing resource
allocation and enhancing performance in diverse environments.
Q6 QUESTION 6 OF 202
Statistical reporting
CORRECT ANSWER
References a report delivered by computational statistics of the detected events, primarily targeting human users for report generation
RATIONALE
Statistical reporting encompasses the systematic collection and analysis of data to summarize findings, enabling informed decision-making
based on empirical evidence. This process primarily focuses on delivering insights to human users, enhancing their understanding of trends
and patterns within the data.
Q7 QUESTION 7 OF 202
Digi.me
CORRECT ANSWER
Allows users the ability to collect their own personal data from many accounts and services like social media, health, finance, etc. The
data gets stored on a personal cloud service of their choice and gets synched with a mobile app.
Page 3
, RATIONALE
me empowers users by enabling them to aggregate personal data from various platforms, enhancing data ownership and control. This process
involves storing information securely on a chosen cloud service while synchronizing it with a mobile application for convenient access and
management.
Q8 QUESTION 8 OF 202
Which 3 factors does colocation capitalize on to create the most effective outcome for end users?
CORRECT ANSWER
Distance, latency, and reliability
RATIONALE
Colocation enhances performance by minimizing distance to reduce latency, thereby achieving faster data transfer rates and improving real-
time application responsiveness. Additionally, colocated environments typically offer higher reliability through redundant systems and
improved uptime, which collectively optimize user experience.
Q9 QUESTION 9 OF 202
AMI (Advanced Metering Infrastructure)
CORRECT ANSWER
Integrated system of smart meters, communication networks and data management systems that enable two-way communication
between utilities and customers
RATIONALE
An integrated system of smart meters, communication networks, and data management facilitates real-time data exchange, empowering
utilities to optimize energy distribution and enhancing customer engagement through usage insights. This concept exemplifies the shift
towards smart grid technology, enabling improved efficiency and reliability in energy management.
Q10 QUESTION 10 OF 202
vAAA (Virtual Authentication, Authorization, Accounting)
CORRECT ANSWER
VNF delivering AAA, features two distinct service modes, namely blockchain-based and OAUTH2.0 service.
RATIONALE
0 for secure delegated access, enhancing both security and scalability in managing authentication protocols. The integration of these distinct
service modes reflects the evolving landscape of network function virtualization (NFV) to address modern cybersecurity needs.
