What is the sequence of messages that must be exchanged between a DHCP client and a server for the client to receive an IP address?
The DHCP client/server exchange follows a specific four-step sequence known as DORA:
Discover -- Client broadcasts to find available DHCP servers.
Offer -- DHCP server responds with an IP address offer.
Request -- Client requests the offered IP.
Acknowledgement -- Server confirms the lease.
This ensures dynamic IP configuration and is used in enterprise and home networks.

RFC 2131 -- Dynamic Host Configuration Protocol
Which of the following statements about the system interface on the Nokia 7750 SR is FALSE?
The system interface in Nokia SR OS is a loopback-style logical interface that represents the router itself. It is used for:
Router ID assignment (if not manually set)
Source IP for control-plane protocols (OSPF, BGP)
Reachability testing
Important properties:
It is type loopback
It exists by default
If router ID is unset, it uses the system IP address
But the IP address on the system interface does not need to be /32
It can have other prefix lengths, especially in service provider scenarios.
Thus, Option B is FALSE.

In MAC address 00-20-60-CE-2B-28, which part is the Organisationally Unique Identifier (OUI)?
A MAC address (Media Access Control address) is a 48-bit identifier typically expressed in six groups of two hexadecimal digits (e.g., 00-20-60-CE-2B-28). It consists of two key parts:
OUI (Organizationally Unique Identifier) -- The first 24 bits (or first 3 octets, e.g., 00-20-60) are assigned by the IEEE to hardware manufacturers. This identifies the vendor or manufacturer.
Device Identifier (NIC Specific) -- The remaining 24 bits (e.g., CE-2B-28) are assigned uniquely by the vendor to each device/interface.
So in the address 00-20-60-CE-2B-28:
00-20-60 is the OUI
CE-2B-28 is the device-specific portion
Thus, the correct answer is D. 00-20-60.

What is the purpose of a broadcast IP address?
A broadcast IP address is used to send a message to all devices on a specific IP subnet. This address is the highest address in the subnet (i.e., all host bits set to 1).
Example: In 192.168.1.0/24 broadcast is 192.168.1.255.
It is used for purposes like ARP requests or DHCP discovery.
Option A is correct -- refers to all hosts in a subnet.
Option B refers to multicast, not broadcast.
Option C might refer to anycast, which is different.
Option D describes a unicast address.

Which of the following is a characteristic of Link State protocols?
Link-State routing protocols (e.g., OSPF, IS-IS) operate by:
Each router flooding link-state advertisements (LSAs) throughout the network.
Every router constructs a complete map of the network topology.
Then each router runs the SPF algorithm to compute optimal paths.
Option C is correct -- routers know the entire network topology.
Option A is Distance Vector behavior (e.g., RIP).
Option B is not efficient or accurate for Link-State.
Option D -- hop-count is used in Distance Vector (e.g., RIP).
