Ultimate CCNA Question Bank : 500+ Exams questions ! Part 01
A CCNA Question Bank is a curated collection of practice exam questions designed to help candidates prepare for Cisco's 200-301 CCNA certification. It mirrors the actual exam structure by testing core networking domains—including Network Fundamentals, Network Access, IP Connectivity, IP Services, Security Fundamentals, and Automation/Programmability.
Question 1 / 15
When a router receives a packet on an interface, how does it determine the next-hop IP address and the outgoing interface to forward the packet toward its ultimate destination?
It compares the packet’s source MAC address to the ARP table to find the matching port.
it performs a longest prefix match by looking up the packet’s destination IP address in its routing table.
It broadcasts an ICMP Echo Request to all active interfaces to discover the fastest path.
It inspects the Transport layer port numbers (TCP/UDP) to map the packet to a specific VLAN.
Question 2 / 15
When a Layer 2 switch receives an incoming frame with a destination MAC address that is not currently listed in its MAC address table (CAM table), what action does the switch take?
It drops the frame immediately and sends an ICMP Destination Unreachable message back to the source.
It floods the frame out of all active ports on the switch except the port on which the frame was received.
It forwards the frame directly to the default gateway router for resolution.
It buffers the frame in memory and sends an ARP broadcast out all interfaces to discover the owner.
Question 3 / 15
An administrator is subnetting a network using the IPv4 address 192.168.10.0/26. What is the usable number of host IP addresses available per subnet?
30
62
64
126
Question 4 / 15
Which OSPF packet type is responsible for discovering neighbors, establishing adjacencies, and ensuring ongoing bidirectional communication on a network link?
Database Description (DBD)
Hello Packet
Link State Request (LSR)
Link State Update (LSU)
Question 5 / 15
Which protocol is a Cisco proprietary protocol used to negotiate trunking links between switches, automatically determining whether a link should become an active trunk or remain in access mode?
802.1Q
VTP (VLAN Trunking Protocol)
DTP (Dynamic Trunking Protocol)
STP (Spanning Tree Protocol)
Question 6 / 15
When configuring a standard IPv4 Access Control List (ACL) on a Cisco router, what is the best practice for its placement within the network topology?
As close to the source of the traffic as possible.
As close to the destination of the traffic as possible.
On the core routing layer to minimize processing overhead.
Exclusively on the edge router facing the ISP.
Question 7 / 15
In traditional 802.1D Spanning Tree Protocol (STP), what is the correct chronological sequence of port states that a switch port transitions through from the time it is activated until it enters the active forwarding state?
Disabled $\rightarrow$ Blocking $\rightarrow$ Forwarding
Blocking $\rightarrow$ Listening $\rightarrow$ Learning $\rightarrow$ Forwarding
Listening $\rightarrow$ Learning $\rightarrow$ Forwarding $\rightarrow$ Blocking
Blocking $\rightarrow$ Learning $\rightarrow$ Listening $\rightarrow$ Forwarding
Question 8 / 15
Which wireless security protocol introduced for WPA3 provides individual data encryption for each client device connected to an open or public Wi-Fi network, protecting user traffic from eavesdropping?
WEP (Wired Equivalent Privacy)
WPA2-Enterprise
OWE (Opportunistic Wireless Encryption)
TKIP (Temporal Key Integrity Protocol)
Question 9 / 15
Which Cisco IOS global configuration command is used to enable the routing process for IPv6, allowing a router to forward IPv6 traffic between its interfaces?
ip routing
ipv6 unicast-routing
ipv6 enable
ipv6 route 0.0.0.0/0
Question 10 / 15
Which Cisco IOS global configuration command is used to enable the IPv4 routing protocol process for OSPF using Process ID 10 and enter router configuration mode?
router ospf 10
ip ospf 10 area 0
enable router ospf 10
network 10.0.0.0 0.255.255.255 area 0
Question 11 / 15
When configuring a port-channel using LACP (Link Aggregation Control Protocol) in an active-to-active setup between two Cisco switches, what mode must be configured on both ends of the link?
On and On
Active and Active
Desirable and Desirable
Auto and Desirable
Question 12 / 15
In Cisco's Hot Standby Router Protocol (HSRP) version 1, what is the standard format of the virtual MAC address assigned to the standby router group?
0007.54xx.xxxx (where xx.xxxx represents the VLAN ID in hexadecimal)
0000.0c07.acxx (where xx represents the HSRP group number in hexadecimal)
5400.0001.xxxx (where xxxx represents the last two octets of the virtual IP address)
FFFF.FFFF.FFFF (a Layer 2 broadcast address used for all gateway communications)
Question 13 / 15
Which of the following IPv6 address types is automatically configured on an interface using the EUI-64 format (or randomized methods) and is strictly limited to communication on that single local link only?
Global Unicast Address (GUA)
Unique Local Address (ULA)
Link-Local Address (LLA)
Anycast Address
Question 14 / 15
When configuring Port Security on a Cisco switch interface, what is the default violation mode if a port receives traffic from a MAC address that exceeds the maximum allowed limit and no specific mode is manually configured?
Shutdown
Restrict
Protect
Drop
Question 15 / 15
Which of the following wildcard masks is correctly paired with its matching subnet mask to match a network prefix of 192.168.10.0/28?
Wildcard mask: 0.0.0.15 | Subnet mask: 255.255.255.240
Wildcard mask: 0.0.0.63 | Subnet mask: 255.255.255.192
Wildcard mask: 0.0.0.255 | Subnet mask: 255.255.255.0
Wildcard mask: 0.0.3.255 | Subnet mask: 255.255.252.0
