Which query is made by one name server to another name server?
- A.
  
  Dynamic host configuration protocol (DHCP) query
- B.
  
  Domain name service (DNS)query
- C.
  
  Recursive query
- D.
  
  Non-recursive query
Correct Answer
D. Non-recursive query

Explanation
A non-recursive query is made by one name server to another name server. In a non-recursive query, the name server receiving the query will respond with the best answer it has available, even if it does not have the complete information. If the queried name server does not have the requested information, it will refer the querying name server to another name server that might have the answer. This process continues until the querying name server receives a complete answer or reaches the maximum number of referrals allowed.

Which software program manages an IP address allocation for a network?
- A.
  
  Dynamic host configuration protocol (DHCP)
- B.
  
  Domain name service (DNS)
- C.
  
  Active directory (AD)
- D.
  
  DHCP server
Correct Answer
A. Dynamic host configuration protocol (DHCP)

Explanation
DHCP is a software program that manages the allocation of IP addresses for a network. It automatically assigns IP addresses to devices on the network, eliminating the need for manual configuration. DHCP ensures efficient use of IP addresses by dynamically allocating and reclaiming them as devices join or leave the network. It also provides other network configuration information, such as subnet mask and default gateway, to the devices. Therefore, DHCP is the correct answer for the software program that manages IP address allocation for a network.

  Pool
- B.
  
  Range
- C.
  
  Scope
- D.
  
  Zone
Correct Answer
C. Scope

Explanation
A DHCP server manages a group of IP addresses known as a "scope." A scope is a range of IP addresses that the DHCP server can assign to client devices on a network. The DHCP server dynamically allocates IP addresses from the scope to devices as they connect to the network, ensuring that each device has a unique IP address. Therefore, "scope" is the correct answer in this context.
