The Organizationally Unique Identifier (OUI) is the last three bytes of a MAC address.
Subnetting reduces network broadcast traffic and improves performance.
The minimum Ethernet frame size is 64 bytes, and the maximum is 1518 bytes.
In cut-through switching, the switch checks for frame errors before forwarding.
A MAC address is a 48-bit binary value usually represented as 12 hexadecimal digits.
Ethernet operates only at the Physical layer of the OSI model.
Switches learn MAC addresses by examining the destination address of incoming frames.
Store-and-forward switching forwards frames without checking for CRC errors.
IPv6 still requires NAT for internet communication.
The default gateway is used to reach devices within the same subnet.
The show ip route command on a Cisco router displays only the IPv6 routing table.
Broadcast MAC addresses are represented in hexadecimal as FF-FF-FF-FF-FF-FF.
Link-local IPv6 addresses (FE80::/10) are automatically assigned to all IPv6 interfaces.
RAM in a router is non-volatile and retains data after power loss.
Store-and-forward switching receives the entire frame and checks its CRC before forwarding.
Full-duplex communication allows sending and receiving simultaneously.
Auto-MDIX automatically detects cable types and adjusts connections.
Telnet is considered secure for remote CLI access.
The network layer is responsible for routing packets between different networks.
Borrowing host bits decreases the number of available subnets.
IP is a connectionless protocol, meaning no end-to-end connection is established before sending data.
Ethernet supports only half-duplex transmission.
An IPv4 packet is always delivered reliably and in sequence.
The Time-to-Live (TTL) field in IPv4 is reduced by one at each router hop.
IPv6 addresses written with double colons (::) may have multiple sections compressed at once.
IPv6 uses a 128-bit address space.
ROM stores the bootstrap program and limited IOS instructions.
The router boot process includes POST, loading IOS, and loading the startup configuration.
A switch does not normally require an IP address to forward traffic.
The ip default-gateway command is used to configure a switch’s management gateway.
