,Network Fundamentals (Q1–Q8)
Q1. A network engineer is designing a campus network that requires fault tolerance
and reduced broadcast domain sizes. Which design approach best satisfies both
requirements?
A. Single Layer 2 flat network with redundant uplinks
B. Hierarchical design using VLAN segmentation and redundant distribution switches
C. Single router connecting all access switches
D. Hub-and-spoke Layer 2 topology
Correct Answer: 🔴 B. Hierarchical design using VLAN segmentation and
redundant distribution switches
Explanation: 🔹 A hierarchical architecture improves scalability, fault tolerance, and
manageability. VLAN segmentation reduces broadcast domains, while redundant
distribution switches provide resilience. Option A still suffers from large broadcast
domains. Option C creates a single point of failure. Option D lacks scalability and
redundancy.
Q2. An administrator observes that a host with IP address 172.20.14.25/23 needs to
communicate with another device. Which address belongs to the same subnet?
A. 172.20.15.200
B. 172.20.16.1
C. 172.20.17.10
D. 172.20.18.5
Correct Answer: 🔴 A. 172.20.15.200
Explanation: 🔹 A /23 mask (255.255.254.0) groups addresses in blocks of two Class C
ranges. The subnet containing 172.20.14.25 spans 172.20.14.0 through 172.20.15.255.
Therefore, 172.20.15.200 belongs to the same subnet. The other addresses fall outside
the subnet boundary.
,Q3. Which characteristic is associated with the TCP protocol rather than UDP?
A. Low-overhead transmission
B. Connectionless communication
C. Sequencing and acknowledgment mechanisms
D. Real-time voice optimization
Correct Answer: 🔴 C. Sequencing and acknowledgment mechanisms
Explanation: 🔹 TCP establishes reliable communication through sequencing,
acknowledgments, retransmissions, and flow control. UDP provides lower overhead and
is commonly used for real-time applications where speed is prioritized over guaranteed
delivery.
Q4. A company plans to deploy IPv6 throughout its enterprise. Which IPv6 address
type is intended for communication with all devices on a local segment?
A. Global Unicast
B. Loopback
C. Anycast
D. Multicast
Correct Answer: 🔴 D. Multicast
Explanation: 🔹 IPv6 replaces broadcast functionality with multicast. Multicast
addresses allow packets to be delivered to multiple interested devices. Global Unicast
identifies individual hosts, Loopback refers to the local device, and Anycast targets the
nearest member of a group.
Q5. Which OSI layer is responsible for logical addressing and routing decisions?
A. Layer 2
B. Layer 3
C. Layer 4
D. Layer 7
, Correct Answer: 🔴 B. Layer 3
Explanation: 🔹 Layer 3, the Network Layer, handles logical addressing and packet
routing. Layer 2 handles MAC addressing and switching, Layer 4 manages transport
services, and Layer 7 provides application services.
Q6. During packet encapsulation, what information is added at Layer 2?
A. TCP port numbers
B. Application headers
C. Source and destination MAC addresses
D. DNS records
Correct Answer: 🔴 C. Source and destination MAC addresses
Explanation: 🔹 Layer 2 frames contain MAC addresses used for local delivery across a
LAN segment. TCP port numbers belong to Layer 4, while application data is associated
with upper layers.
Q7. Which topology offers the highest availability when implemented with redundant
links and rapid convergence protocols?
A. Bus
B. Ring without redundancy
C. Partial Mesh
D. Daisy Chain
Correct Answer: 🔴 C. Partial Mesh
Explanation: 🔹 Partial mesh designs provide multiple communication paths,
improving fault tolerance and availability. Bus and daisy-chain topologies introduce
significant single points of failure.
Q8. What is the primary purpose of a default gateway?
