1In the OSI reference model, which layer is responsible for logical addressing and selecting the best path for data to travel between different networks?
A.Layer 2 (Data Link)
B.Layer 4 (Transport)
C.Layer 3 (Network)
D.Layer 1 (Physical)
Explanation: Layer 3, the Network layer, handles logical addressing (such as IP addresses) and routing, which is the process of choosing the best path to forward packets between separate networks. Routers operate primarily at this layer.
2A device needs to learn the MAC address that corresponds to a known IPv4 address on the same local network. Which protocol performs this resolution?
A.DNS
B.DHCP
C.ICMP
D.ARP
Explanation: The Address Resolution Protocol (ARP) maps a known IPv4 address to its hardware (MAC) address on a local Ethernet segment. A host broadcasts an ARP request, and the owner of that IP replies with its MAC address so frames can be delivered.
3Which device forwards Ethernet frames based on MAC addresses and, by default, creates a separate collision domain on every port?
A.Hub
B.Switch
C.Repeater
D.Modem
Explanation: A switch is a Layer 2 device that builds a MAC address table and forwards frames only out the port where the destination resides. Each switch port is its own collision domain, allowing full-duplex communication without contention.
4What is the primary purpose of creating VLANs on a switched network?
A.To logically segment a single physical switch into separate broadcast domains
B.To increase the physical port speed of the switch
C.To encrypt all traffic passing through the switch
D.To convert IPv4 addresses to IPv6 addresses
Explanation: A VLAN (Virtual LAN) logically divides a physical switch into multiple isolated broadcast domains. Devices in different VLANs cannot communicate directly without a router or Layer 3 switch, which improves security, reduces broadcast traffic, and organizes the network by function.
5A host is configured with the IP address 192.168.10.45 and a subnet mask of 255.255.255.0. What is the network address of this subnet?
A.192.168.10.1
B.192.168.0.0
C.192.168.10.0
D.192.168.10.255
Explanation: With a /24 mask (255.255.255.0), the first three octets identify the network and the last octet identifies the host. Setting the host portion to zero gives the network address 192.168.10.0.
6How many usable host addresses are available in a subnet that uses a /24 prefix length?
A.256
B.510
C.128
D.254
Explanation: A /24 leaves 8 host bits, giving 2^8 = 256 total addresses. Subtracting the network address and the broadcast address leaves 254 usable host addresses.
7Which transport-layer protocol provides connection-oriented, reliable delivery with acknowledgements and retransmission of lost segments?
A.UDP
B.IP
C.TCP
D.ARP
Explanation: TCP (Transmission Control Protocol) is connection-oriented and reliable. It establishes a session with a three-way handshake, sequences segments, acknowledges received data, and retransmits anything lost, making it ideal for applications that require accuracy.
8A network administrator wants devices to receive their IP address, subnet mask, default gateway, and DNS server automatically. Which protocol provides this?
A.SNMP
B.FTP
C.DHCP
D.NTP
Explanation: The Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses and related parameters such as subnet mask, default gateway, and DNS servers to clients. This eliminates manual configuration and reduces addressing errors.
9Which of the following is a private IPv4 address range as defined by RFC 1918?
A.172.16.0.0/12
B.8.8.8.0/24
C.200.10.10.0/24
D.1.1.1.0/24
Explanation: RFC 1918 reserves three private ranges for internal use: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. The 172.16.0.0/12 block (172.16.0.0 through 172.31.255.255) is one of them and is not routable on the public internet without NAT.
10On an Ethernet trunk link carrying multiple VLANs, which IEEE standard defines how a VLAN tag is inserted into frames?
A.IEEE 802.1Q
B.IEEE 802.3
C.IEEE 802.11
D.IEEE 802.1X
Explanation: IEEE 802.1Q defines VLAN tagging by inserting a 4-byte tag into the Ethernet frame header that includes the VLAN ID. This lets a single trunk link carry traffic for many VLANs between switches.

About the Extreme Networks Associate (ECA) Exam

The Extreme Networks Associate (ECA) credential is the free, entry-level qualification from Extreme Academy's Networking Fundamentals program. It validates foundational, largely vendor-neutral networking knowledge while introducing Extreme's product portfolio. Candidates study how networks work (OSI and TCP/IP, switching, routing, IP addressing and subnetting, and VLANs), how to build secure and robust wireless networks, and how to design scalable and mission-critical networks with redundancy and high availability. The program also covers Extreme product families such as ExtremeXOS/Switch Engine, Extreme Fabric Connect (SPB), ExtremeCloud IQ, and ExtremeControl, along with networking industry and career foundations. The exam is multiple-choice, proctored, takes about one hour, and requires roughly 75% to pass; both the courses and the exam are free.

Extreme Networks Associate (ECA) Study Tips from Top Performers

1Be fluent in the OSI and TCP/IP models and know which devices and protocols live at each layer; many questions test whether something is a switching (Layer 2) or routing (Layer 3) function.
2Practice IPv4 subnetting until network address, broadcast address, and usable host counts for /24, /25, /26, /27, and /28 are automatic, and review binary-to-decimal conversion.
3Learn the wireless security progression WEP to WPA to WPA2 (AES-CCMP) to WPA3 (SAE, Protected Management Frames, Enhanced Open), plus 802.1X with RADIUS for enterprise authentication.
4Understand resilience building blocks: redundancy, link aggregation, spanning tree, first-hop gateway redundancy, segmentation, and why fast convergence matters for mission-critical networks.
5Know Extreme's portfolio mapping: EXOS became Switch Engine, VOSS became Fabric Engine, Fabric Connect uses SPB with I-SIDs, and ExtremeCloud IQ provides unified cloud management while ExtremeControl handles access control.
