The document addresses network subnetting for an administrator managing a 192.168.1.0/24 network, detailing departments with varying computer counts and the need for variable-length subnet masking (VLSM). It includes quiz questions on classful subnetting, TCP/IP model layers, and key networking concepts. Additionally, it briefly discusses differences between simulators and emulators, scenarios for avoiding simulation, and contrasts between LAN and WAN networks.
Network simulation questions
- 1. Q1 An administrator has 192.168.1.0/24 network with four different departments (sales, purchase, accounts and management) with different number of hosts. Sales department has 60 computers, purchase department has 30 computers, accounts has 11 computers and Management has 5 computers. 1- Identify the IP class. How many host IPs can be used as subnet mask. 2- Develop a subnetting scheme for each department to reduce the number of wasted IPs using VLSM. Q2 Choose the right answer and write the correct answer. 1. You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use. a. 255.255.255.192 b. 255.255.255.224 c. 255.255.255.240 d. 255.255.255.248 2. The network address of 172.16.0.0/19 provides how many subnets and hosts. a. 7 subnets, 30 hosts each b. 8 subnets, 8,190 hosts each c. 8 subnets, 2,046 hosts each d. 7 subnets, 2,046 hosts each 3. The TCP/IP model consists of _______ layers. a. Three b. Five c. Seven d. Eight 4. The _______ layer changes bits into electromagnetic signals. a. Physical b. Data link c. Transport d.
