Cisco Certified Network Associate Exam Practice Test

The 200-301 CCNA practice page covers foundational network administration concepts, including IP connectivity, Ethernet switching, wireless security, and basic network services. Its question bank samples tasks such as interpreting IPv6 addressing, selecting VLAN port modes, understanding spanning tree behavior, and identifying how routing and access-control mechanisms handle traffic.

About the Cisco Certified Network Associate Exam

Network technicians use these concepts to connect endpoints, segment Layer 2 traffic, and support communication across IPv4 and IPv6 networks. Practice topics include recognizing eBGP autonomous system numbers, distinguishing link-local from other IPv6 addresses, and understanding how router advertisements provide local configuration information. Switching questions involve 802.1Q-tagged traffic and STP behavior that helps prevent Layer 2 loops. Other scenarios test selection of wireless protection, use of NTP for consistent log timestamps, Ethernet FCS error detection, and extended ACL criteria such as protocol and port numbers. These skills help with configuring access ports, checking packet paths, applying traffic filters, and diagnosing common connectivity or service issues. The bank’s examples provide a sampling of network terminology and decisions rather than a stated map of official exam coverage.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

Which description best fits the function of a routing protocol's autonomous system number in eBGP?

  1. AIt identifies the routing domain to which a BGP speaker belongs
  2. BIt specifies the IPv4 subnet mask for a neighbor
  3. CIt selects the switch's spanning-tree root port
  4. DIt identifies the UDP port used by DNS
Show answerCorrect answer: A

An autonomous system number identifies a routing domain under a common administration. eBGP uses AS numbers to distinguish neighboring autonomous systems and to support interdomain routing decisions.

Question 2

Which wireless security protocol is generally preferred over WEP for protecting a modern Wi-Fi network when supported by the devices?

  1. AWPA3
  2. BWEP
  3. COpen authentication
  4. DTelnet
Show answerCorrect answer: A

WPA3 is a modern Wi-Fi security protocol and is generally preferred when supported. WEP is obsolete and weak, open authentication provides no comparable link-layer protection, and Telnet is not a Wi-Fi security protocol.

Question 3

Which IPv6 mechanism allows a host to learn local network parameters, such as the default router, from router advertisements?

  1. ANeighbor Discovery Protocol
  2. BFile Transfer Protocol
  3. CSimple Network Management Protocol
  4. DAddress Resolution Protocol
Show answerCorrect answer: A

IPv6 Neighbor Discovery includes Router Solicitation and Router Advertisement messages. Hosts use router advertisements to discover routers and learn relevant on-link configuration information.

Question 4

A switch port connects to a computer that sends traffic for several VLANs using 802.1Q tags. Which port mode is generally appropriate?

  1. AAccess mode
  2. BTrunk mode
  3. CRouted mode
  4. DMonitor mode
Show answerCorrect answer: B

A trunk can carry traffic for multiple VLANs over one link, with 802.1Q tags identifying VLAN membership. An access port normally carries traffic for one VLAN and sends frames untagged to an endpoint.

Question 5

Which IPv6 address is used to identify a specific interface on a local link and is not routed beyond that link?

  1. ALink-local address
  2. BGlobal unicast address
  3. CMulticast address
  4. DAnycast address
Show answerCorrect answer: A

An IPv6 link-local address is used for communication on the local link and is not forwarded by routers. Global unicast addresses are routable, while multicast and anycast have different delivery semantics.

Question 6

A network administrator wants devices to use a consistent time reference for timestamps in logs. Which protocol is commonly used for clock synchronization?

  1. ANTP
  2. BTFTP
  3. CSMTP
  4. DLLDP
Show answerCorrect answer: A

Network Time Protocol (NTP) synchronizes clocks on networked devices with time sources, helping make timestamps consistent across logs and systems.

Question 7

In a standard Ethernet frame, what does the Frame Check Sequence (FCS) help a receiving device detect?

  1. ATransmission errors in the frame
  2. BThe sender's default gateway
  3. CThe application protocol in the payload
  4. DThe VLAN's assigned IPv4 subnet
Show answerCorrect answer: A

The Ethernet FCS contains a cyclic redundancy check value used to detect corruption of the frame during transmission. It does not identify routing or application-layer configuration.

How to use this practice test

Preparation tips

  • Practice distinguishing IPv6 link-local addresses, router-advertisement information, and all-nodes multicast traffic by identifying their scope and intended recipients.
  • Trace how 802.1Q tags and switch port modes carry traffic for one or multiple VLANs, and connect STP blocking behavior to loop prevention.
  • For ACL scenarios, identify whether the requirement depends on source or destination addresses, protocol, or transport-layer ports before selecting a rule type.
  • Review the purposes of eBGP autonomous system numbers, NTP clock synchronization, and Ethernet FCS checks, and relate each to a practical network operation.
