Introduction
This assessment is designed to evaluate comprehensive knowledge and practical skills required for the Cisco
Certified Network Associate certification. The exam covers essential networking concepts, switching and
routing technologies, IP services, security fundamentals, and modern automation capabilities. Candidates will
encounter multiple-choice questions and scenario-based problems that test both theoretical understanding and
real-world application. The assessment emphasizes critical decision-making in professional networking
environments, preparing individuals for roles involving network configuration, verification, troubleshooting,
and optimization in enterprise settings. Success requires mastery of foundational theory alongside applied
professional knowledge and the ability to address regulatory compliance, ethics, and industry standards.
,Section One: Questions 1–100
Question 1
Which layer of the OSI model is responsible for end-to-end communication and error recovery?
A. Network layer
B. Transport layer
C. Session layer
D. Data link layer
🟢 Correct answer: B
🔴 RATIONALE: The Transport layer (Layer 4) provides end-to-end communication, error recovery, and flow
control between source and destination hosts. It ensures data integrity through mechanisms like TCP
acknowledgments and retransmissions.
Question 2
What is the maximum number of usable IP addresses in a IPv4 subnet with a prefix length of /26?
,A. 30
B. 62
C. 126
D. 254
🟢 Correct answer: B
🔴 RATIONALE: A /26 subnet has 6 bits for host addresses (32 - 26 = 6), which equals 2^6 = 64 total
addresses. Subtracting the network address and broadcast address gives 64 - 2 = 62 usable IP addresses.
Question 3
Which Cisco command is used to configure a static route to network 192.168.10.0/24 via gateway 10.0.0.1?
A. ip route 192.168.10.0 255.255.255.0 10.0.0.1
B. route add 192.168.10.0 10.0.0.1
C. ip static 192.168.10.0 255.255.255.0 10.0.0.1
D. route static 192.168.10.0 10.0.0.1
🟢 Correct answer: A
, 🔴 RATIONALE: The correct Cisco IOS command syntax for static route configuration is "ip route
<destination> <mask> <gateway>". Option A follows this exact format with the proper destination network,
subnet mask, and next-hop gateway.
Question 4
What type of VLAN is automatically created on Cisco switches and cannot be deleted?
A. Access VLAN
B. Default VLAN
C. Voice VLAN
D. Tunnel VLAN
🟢 Correct answer: B
🔴 RATIONALE: The Default VLAN (VLAN 1) is automatically created on all Cisco switches when they are
initialized. It serves as the management VLAN by default and cannot be deleted or removed from the switch
configuration.
