Exam N10-008 topic 1 question 83 discussion

IP reservation assigns the same IP upon requesting IP renewal by a client.

Perhaps you have noticed that DHCP dynamically assigns IP addresses and subnet masks to clients, but they need more IP addressing information than that in order to communicate properly on the network. For example, clients need DNS server addresses, they need a default gateway assigned, and they might even need the IP addresses associated with other key services, such as NTP and TFTP servers on the network. Your DHCP server can provide all this required IP addressing information. You enable this as part of the scope options you can configure on the DHCP server. The scope is the addresses that your DHCP server will lease out to clients. The scope options include the additional address information that must be distributed and can also include settings such as the lease time.

Static IP without reservation could have IP conflicts, the best way is to either have the IP outside of the DHCP scope and static it or you do a IP reservation with MAC address

DHCP reservations allow the DHCP server to pre-set an IP address to a specific client based on its MAC address. This ensures that the client will always get the same IP address from the DHCP server when it connects to the network. DHCP reservations are usually used with servers or printers on your internal network and are rarely used with end-user devices.

E is incorrect because the IP is not dynamically assigned as in DHCP

B - correct

Im assuming you cannot statically assign an IP using DHCP which uses dyanamic assignment. IP reservation makes much more sense to me

It is a Reservation, we do it all the time at work with printers :)

It's E In DHCP Server when you do a reservation, you don't write down the IP Address but if you want to assign an IP to a device you must write the MAC Address.

I believe the answer is static assignment thou (B. reservation) is also correct but since they didn't specify properly which reservation such as address reservation. Therefore I would choose E.

Easy it is B

Scope options aren't used to configure CLIENT IPs. Dynamic assignment doesn't guarantee the same particular IP address. Exclusion is used to reserve a pool of statically assignable IPs, which are OUTSIDE of the DHCP scope. Therefore, DHCP reservation is the only logical answer.
