2026 CISCO CCNA 200-301 Exam New Latest Version from
Actual Past Exam with All 100 Questions, 100% Correct
Answers and Rationale
IMPORTANT EXAM TIPS
1. Time Management: With approximately 90 seconds per question, answer questions you
know first and mark challenging ones for review .
2. Question Types: Be prepared for multiple-choice (single and multiple answers), drag-
and-drop, simulations (Sims), and simlets (Sims with topology) .
3. Practice Simulations: Performance-based questions require hands-on experience with
Cisco CLI and configuration tasks .
4. Read Carefully: Misunderstanding questions costs valuable points. Read thoroughly, but
don't dwell on one question .
5. Trust Your Instinct: Avoid second-guessing unless certain of a mistake. Changing
answers may lead away from correct responses .
6. Know Your Subnetting: Master IP subnetting quickly as it's foundational to many
questions .

DOMAIN 1: NETWORK FUNDAMENTALS (20%)
Questions 1-20

Question 1
Which two characteristics describe Ethernet technology? (Choose two.)
A. It uses a star topology
B. It is supported by IEEE 802.3 standards
C. It uses a ring topology
D. It uses CSMA/CD access method
E. It is supported by IEEE 802.5 standards
Correct Answer: B, D
Rationale: Ethernet is defined by IEEE 802.3 standards and uses CSMA/CD (Carrier Sense
Multiple Access with Collision Detection) as its media access control method. Ethernet typically
uses star or extended star topologies, not ring. IEEE 802.5 defines Token Ring .

Question 2
Which TCP/IP model layer corresponds to the OSI model's Layer 3?
A. Network Access layer
B. Internet layer
C. Transport layer
D. Application layer
Correct Answer: B
Rationale: The TCP/IP model's Internet layer corresponds to the OSI model's Network layer
(Layer 3). It handles logical addressing, routing, and packet forwarding .

Question 3

,What is the primary difference between TCP and UDP?
A. TCP is connection-oriented and provides reliable delivery; UDP is connectionless and
provides best-effort delivery
B. TCP is faster than UDP
C. UDP uses sequence numbers and acknowledgments; TCP does not
D. TCP supports broadcast while UDP does not
Correct Answer: A
Rationale: TCP is connection-oriented and provides reliable delivery through sequencing,
acknowledgments, and retransmissions. UDP is connectionless and provides best-effort delivery
with minimal overhead, making it faster but unreliable .

Question 4
What is the subnet address for a host with IP address 192.168.1.130/25?
A. 192.168.1.0
B. 192.168.1.128
C. 192.168.1.192
D. 192.168.1.255
Correct Answer: B
Rationale: A /25 subnet mask (255.255.255.128) creates 128-host subnets. The first subnet is
192.168.1.0/25 (hosts 1-126). The second subnet is 192.168.1.128/25 (hosts 129-254). Address
130 falls in the 192.168.1.128 subnet .

Question 5
Which IPv6 address type is equivalent to a public IPv4 address?
A. Link-local
B. Unique local
C. Global unicast
D. Multicast
Correct Answer: C
Rationale: Global unicast addresses are globally unique and routable on the internet, similar to
public IPv4 addresses. They begin with 2000::/3. Link-local addresses (FE80::/10) are for local
link communication only .

Question 6
A network engineer needs to connect two devices directly without a switch. Which cable type
should be used between two similar devices (e.g., two routers)?
A. Straight-through cable
B. Crossover cable
C. Rollover cable
D. Fiber-optic cable
Correct Answer: B
Rationale: A crossover cable is used to connect similar devices directly (router-router, switch-
switch, PC-PC). Straight-through cables connect unlike devices (PC-switch, router-switch).
Rollover cables are used for console connections .

Question 7

, Which Layer 2 switch function learns MAC addresses and populates the MAC address table?
A. Frame filtering
B. Frame switching
C. Frame flooding
D. MAC learning
Correct Answer: D
Rationale: MAC learning is the process where switches examine the source MAC address of
incoming frames and associate them with the receiving port, populating the MAC address table
for future forwarding decisions .

Question 8
What is the purpose of Power over Ethernet (PoE)?
A. To provide electrical power to devices through Ethernet cables
B. To increase network bandwidth
C. To secure wireless transmissions
D. To connect devices over longer distances
Correct Answer: A
Rationale: PoE delivers electrical power to devices like IP phones, wireless access points, and
IP cameras through standard Ethernet cabling, eliminating the need for separate power supplies .

Question 9
Which two IP addresses are private addresses? (Choose two.)
A. 10.0.0.1
B. 172.32.0.1
C. 192.168.1.1
D. 8.8.8.8
E. 169.254.1.1
Correct Answer: A, C
Rationale: Private IP addresses are defined in RFC 1918: 10.0.0.0/8, 172.16.0.0/12, and
192.168.0.0/16. Address 172.32.0.1 is public (outside 172.16.0.0-172.31.255.255). 169.254.x.x
are APIPA addresses. 8.8.8.8 is Google's public DNS .

Question 10
What is the binary equivalent of decimal 192?
A. 11000000
B. 10101010
C. 11110000
D. 11001100
Correct Answer: A
Rationale: 192 in binary is 11000000. 128 + 64 = 192. Bits: 128 (1), 64 (1), 32 (0), 16 (0), 8 (0),
4 (0), 2 (0), 1 (0) = 11000000 .

Question 11
Which Cisco device is designed to connect different networks and perform routing functions?
A. Switch
B. Router
