What happens when a switch receives a frame with a destination MAC address not in its MAC address table?
Answer: The frame is flooded out all ports except the source port
When a switch encounters an unknown destination MAC, it floods the frame out all ports except the ingress port.
Which metric does RIP use to determine the best path to a destination?
Answer: Hop count
RIP uses hop count as its sole metric. Each router along the path counts as one hop, with a maximum of 15.
What is the function of a VLAN in a switched network?
Answer: To create separate broadcast domains within a single switch
VLANs segment a physical switch into multiple logical broadcast domains. Different VLANs require a router for communication.
Which protocol prevents switching loops in a redundant Layer 2 network?
Answer: STP
STP prevents loops by logically blocking redundant ports while keeping them as backups.
What type of route must be manually configured by a network administrator?
Answer: Static route
Static routes are manually configured using 'ip route' and do not adapt to topology changes.
What is the maximum number of usable host addresses in a /26 subnet?
Answer: 62
A /26 has 6 host bits: 2^6 = 64 total, minus 2 (network + broadcast) = 62 usable hosts.
