Ultimate CCNA Question Bank : 500+ Exams questions ! Part 02
A CCNA Question Bank is a curated collection of practice questions, trivia, and practical scenario-based problems modeled after the official Cisco Certified Network Associate (CCNA 200-301) exam. It is designed to test and reinforce technical knowledge across key networking domains—such as Layer 2 switching, Spanning Tree Protocol, VLAN tagging, IP addressing, ACLs, and OSPF routing—helping candidates build hands-on troubleshooting skills and prepare effectively for certification.
Question 1 / 10
In the context of network programmability and REST APIs, which HTTP status code indicates that a request was successful and that a new resource has been successfully created (commonly returned after an HTTP POST request)?
200 OK
201 Created
204 No Content
400 Bad Request
Question 2 / 10
What is the default Administrative Distance (AD) for an OSPF route on a Cisco IOS router?
90
110
120
1
Question 3 / 10
In Cisco Layer 2 security, what is the primary purpose of DHCP Snooping on a switch?
To encrypt DHCP lease assignments across wireless access points.
To prevent rogue DHCP servers from assigning invalid IP configurations to clients by categorizing switch ports as trusted or untrusted.
To dynamically translate private IPv4 addresses into public Internet IP addresses.
To restrict the maximum rate at which DHCP discover packets can be processed by the CPU.
Question 4 / 10
Which of the following data serialization formats used in network programmability and automation relies strictly on indentation, whitespace, and key-value pairs rather than explicit curly braces or brackets?
JSON

Question 6 / 10
In the Spanning Tree Protocol (STP) IEEE 802.1D, which of the following criteria is evaluated first by switches to elect the Root Bridge in a bridged network?
Lowest MAC Address
Lowest Bridge Priority
Highest Port Cost
Highest Interface Bandwidth
Question 7 / 10
Which of the following numerical ranges represents Standard IPv4 Access Control Lists (ACLs) in Cisco IOS?

1 to 99 and 1300 to 1999
500 to 799
1000 to 1199
Question 8 / 10
When a switch or router encapsulates an Ethernet frame with an IEEE 802.1Q tag for VLAN identification, exactly how many bytes of overhead are added to the standard Ethernet frame?
2 bytes
4 bytes
8 bytes
16 bytes
Question 9 / 10
In Rapid Spanning Tree Protocol (RSTP - IEEE 802.1w), which port role is assigned to a switch port that acts as a backup to the root port, is currently in a discarding state, and receives superior BPDUs from a different switch?
Designated Port
Alternate Port
Backup Port
Root Port
Question 10 / 10
In OSPF routing, what is the specific term used for the router that connects an OSPF area to an external network (such as the Internet or another routing domain running BGP or EIGRP) and injects external routes into the OSPF domain?
Designated Router (DR)
Area Border Router (ABR)
Autonomous System Boundary Router (ASBR)
Root Bridge
