Question 1
Which characteristic best distinguishes digital infrastructure
from traditional IT infrastructure?
A. It only consists of physical servers.
B. It focuses exclusively on internet connectivity.
,C. It integrates physical, virtual, cloud, network, data, and
security resources into a scalable digital ecosystem.
D. It eliminates cybersecurity requirements.
Correct Answer: C
Rationale: Modern digital infrastructure combines compute,
networking, storage, cloud services, automation, cybersecurity,
and data platforms into a unified, scalable ecosystem that
supports digital services and business transformation.
Question 2
An enterprise wants applications to continue operating despite
an entire data center failure. Which architectural principle is
MOST important?
A. Single high-capacity server
B. Local storage
C. Geographically redundant high availability
D. Larger hard drives
Correct Answer: C
Rationale: Geographic redundancy ensures workloads remain
available if one region or data center becomes unavailable due
to disasters or outages.
,Question 3
Which technology provides centralized control over network
behavior while separating the control plane from the data
plane?
A. MPLS
B. VLAN
C. Software-Defined Networking (SDN)
D. DHCP
Correct Answer: C
Rationale: SDN separates network intelligence from forwarding
devices, enabling centralized management, automation, and
programmable networking.
Question 4
Which cloud deployment model provides the greatest level of
organizational control?
A. Public Cloud
B. Community Cloud
C. Hybrid Cloud
, D. Private Cloud
Correct Answer: D
Rationale: Private clouds are dedicated to a single organization,
offering maximum customization, governance, and control over
infrastructure.
Question 5
Which networking technology is specifically designed to
improve wide-area network performance using intelligent
traffic routing?
A. Ethernet
B. Fibre Channel
C. SD-WAN
D. Bluetooth
Correct Answer: C
Rationale: SD-WAN dynamically routes traffic across multiple
WAN connections based on application requirements and
network conditions.
