*Introduction*
*The Cisco Certified Network Associate (CCNA) practice exam is designed to*
*evaluate a candidate's proficiency in managing and optimizing modern IT*
*networks. This assessment covers a broad spectrum of technical competencies,
*including routing and switching, wireless access, security protocols, and*
*automation. Comprised of multiple-choice and scenario-based questions, the*
*exam emphasizes real-world application, requiring candidates to demonstrate
*critical thinking and technical decision-making skills. By simulating the*
*complexity of enterprise environments, this test ensures that successful*
, *candidates possess the foundational knowledge required to maintain and*
*secure scalable network infrastructures in diverse professional settings.
Section One: Questions 1–100
Question 1
Which characteristic distinguishes a floating static route from a standard static route?
A. It has a higher administrative distance than the dynamic routing protocol in use.
B. It is used as the primary path for all traffic leaving the local network.
C. It is configured with a lower administrative distance to ensure priority.
D. It automatically updates its next-hop address based on interface status.
🟢 A. It has a higher administrative distance than the dynamic routing protocol in
use.
🔴 Explanation: A floating static route serves as a backup path and is configured with
an administrative distance higher than the primary routing protocol, ensuring it only
enters the routing table if the primary path fails.
Question
2
What is the primary purpose of the Address Resolution Protocol (ARP)?
,A. To map a known IP address to a physical MAC address.
B. To map a known MAC address to a logical IP address.
C. To provide error reporting for IP packet delivery.
D. To assign dynamic IP addresses to hosts on a local network.
🟢 A. To map a known IP address to a physical MAC address.
🔴 Explanation: ARP is used at Layer 2 to resolve a known Layer 3 (IP) address to
its corresponding physical hardware (MAC) address for local link delivery.
Question 3
A network administrator needs to restrict access to the console port of a switch.
Which command sequence should be used?
A. line vty 0 4, password cisco, login
B. line console 0, password cisco, login
C. interface fastethernet 0/1, switchport mode access
D. enable secret cisco
🟢 B. line console 0, password cisco, login
🔴 Explanation: The 'line console 0' command enters the configuration mode for the
physical console port, where a password and login requirement can be established.
, Question 4
Which field in an IPv4 header is used to prevent packets from looping indefinitely on
a network?
A. Protocol
B. Differentiated Services
C. Time to Live (TTL)
D. Type of Service
🟢 C. Time to Live (TTL)
🔴 Explanation: The TTL field is decremented by each router that processes the
packet. If the TTL reaches zero, the packet is discarded, preventing infinite loops.
Question 5
In a Spine-Leaf architecture, which statement is true regarding connectivity?
A. Leaf switches must connect to each other for redundancy.
B. Spine switches are where servers and end-devices connect.
C. Every Leaf switch must connect to every Spine switch.
D. Spine switches are connected in a full mesh with other Spine switches.
