Section 1: Network Fundamentals (20%)
*Focus: Topology architectures, IPv4/IPv6 subnetting, OSI Model, Cloud basics.*
Q1. A network engineer must design a highly scalable data center with predictable
latency where every server is exactly two hops away from any other server. Which
architecture meets this requirement?
A) Three-Tier (Core-Distribution-Access)
B) Spine-Leaf
C) Collapsed Core
D) Peer-to-Peer
Correct Answer: B
RATIONALE: Spine-Leaf architectures provide predictable latency (consistent
hop count) and high scalability, making them standard for modern data centers.
Traditional three-tier designs introduce variable latency .
Q2. Which IPv6 address type is equivalent to IPv4's "broadcast" functionality?
A) Multicast
,B) Anycast
C) Link-Local
D) Unique Local
Correct Answer: A
RATIONALE: IPv6 eliminates broadcast. Multicast (specifically the "All-Nodes"
multicast address FF02::1) is used to achieve the same function.
Q3. Refer to the exhibit. An interface is configured with the IP
address 192.168.25.98/29. What is the broadcast address of this subnet?
A) 192.168.25.100
B) 192.168.25.103
C) 192.168.25.105
D) 192.168.25.110
Correct Answer: B
RATIONALE: /29 = 255.255.255.248 (Block size of 8). Subnets are 96, 104, etc.
.98 belongs to 96-103 range. Broadcast is 103.
Q4. Which cloud service model provides the customer with the infrastructure to
deploy applications onto programmable environments, without managing the
underlying OS or hardware?
A) IaaS (Infrastructure as a Service)
B) PaaS (Platform as a Service)
C) SaaS (Software as a Service)
D) DaaS (Data as a Service)
Correct Answer: B
RATIONALE: CCNA 2026 exams test cloud models. PaaS provides the platform
(OS, runtime), letting devs focus on code; IaaS provides just the hardware .
Q5. A network administrator needs to measure the Round Trip Time (RTT) and
path MTU between two routers. Which command provides this specific
information?
A) traceroute
B) ping
C) telnet
D) show interface
, Correct Answer: A
RATIONALE: traceroute (or tracert) shows hop-by-hop RTT and can indicate
MTU issues, whereas standard ping only tests connectivity end-to-end.
Q6. Which wireless standard, heavily tested in 2026 exams, operates in the 6 GHz
band and introduces OFDMA for high-density environments?
A) 802.11ac (Wi-Fi 5)
B) 802.11n (Wi-Fi 4)
C) 802.11ax (Wi-Fi 6E)
D) 802.11be (Wi-Fi 7)
Correct Answer: C
RATIONALE: Wi-Fi 6E extends 802.11ax into the 6 GHz band. Wi-Fi 7
(802.11be) is emerging, but Wi-Fi 6/E is the current CCNA focus .
Q7. How does a switch handle a frame where the destination MAC address is not
found in the MAC address table?
A) It drops the frame.
B) It sends a NACK to the source.
C) It floods the frame out of all ports except the receiving port.
D) It encapsulates the frame and sends it to the gateway.
Correct Answer: C
RATIONALE: This is an "Unknown Unicast." The switch must flood it to learn
the location of the destination device (Frame flooding) .
Q8. A host is sending a packet to a device on the same local LAN. Which
destination address is used in the Ethernet frame header?
A) The MAC address of the default gateway.
B) The MAC address of the destination device (target).
C) The IP address of the destination device.
D) The broadcast MAC address (FFFF.FFFF.FFFF).
Correct Answer: B
RATIONALE: For local delivery (on the same subnet), the frame uses the
destination device's MAC address. The gateway is only used for remote networks.
Q9. An engineer configures int vlan 1 on a Layer 2 switch with an IP address.
What is the primary purpose of this IP address?
A) To route traffic between VLANs.
B) To allow remote management (SSH/Telnet) of the switch.
