Question 1

Which switching method begins forwarding a frame as soon as the destination MAC address is read, without waiting for the full frame?

Accepted Answer

Cut-through

Answer

Cut-through switching begins forwarding after reading only the first 6 bytes (destination MAC), offering the lowest latency but no error checking.

Question 2

What is the broadcast address of the network 10.0.0.0/8?

Accepted Answer

10.255.255.255

Answer

The broadcast address of 10.0.0.0/8 is formed by setting all host bits to 1, yielding 10.255.255.255.

Question 3

Which protocol is used by routers to automatically learn and share network routing information using a link-state algorithm?

Accepted Answer

OSPF

Answer

OSPF (Open Shortest Path First) is a link-state routing protocol that uses Dijkstra's algorithm to compute the shortest path tree.

Question 4

What is the function of NAT (Network Address Translation)?

Accepted Answer

Map private IP addresses to public IP addresses for internet access

Answer

NAT translates private IP addresses on a local network to a public IP address when communicating with external networks, conserving public address space.

Question 5

Which IEEE standard defines wireless LAN (Wi-Fi) communication?

Accepted Answer

802.11

Answer

IEEE 802.11 is the standard family that defines wireless LAN (WLAN) communication, commonly marketed as Wi-Fi.
