CompTIA Network+ Certification Exam 認定 N10-009 試験問題 (Q180-Q185):
質問 # 180
A network administrator needs to assign IP addresses to a newly installed network. They choose 192.168.1.0
/24 as their network address and need to create three subnets with 30 hosts on each subnet. Which of the following is a valid subnet mask that will meet the requirements?
- A. 255.255.255.192
- B. 255.255.255.240
- C. 255.255.255.128
- D. 255.255.255.224
正解：D
解説：
Understanding the Requirements
* Network Address: 192.168.1.0/24
* The /24 notation means a subnet mask of 255.255.255.0, providing 256 total addresses (192.168.1.0-192.168.1.255).
* Usable hosts: 256 - 2 (network and broadcast) = 254.
* Goal: Create3 subnets, each with30 hosts.
* Each subnet needs enough addresses to accommodate 30 hosts, plus 2 reserved addresses (network and broadcast) per subnet.
* Total addresses per subnet = 30 (hosts) + 2 (network/broadcast) =32 addresses.
Subnetting Basics (Networking Fundamentals)
* Subnet Mask: Determines how many bits are borrowed from the host portion to create subnets.
* Original Mask: /24 (255.255.255.0) = 24 network bits, 8 host bits.
* Formulae:
* Number of subnets = 2
