What the exam tests

What to know about Network Configuration Concepts

Tests your ability to configure and troubleshoot IP addressing, DNS, DHCP, and network settings.

Configure static vs dynamic IP addressing

Set subnet masks and default gateways

Configure DNS server addresses

Set DHCP scope and reservations

Why learners struggle

Why Network Configuration Concepts questions are commonly missed

Learners often confuse the purpose of DNS vs DHCP and misapply subnet masks. These concepts require precise recall of configuration steps and default values.

  • ·Static IP vs DHCP reservation — both assign fixed IPs but differ in management
  • ·Subnet mask vs default gateway — mask defines network, gateway routes traffic
  • ·DNS vs DHCP — DNS resolves names, DHCP assigns addresses
  • ·Public vs private IP addresses — private IPs require NAT for internet
  • ·IPv4 vs IPv6 — different address formats and configuration methods
  • ·APIPA vs static IP — APIPA auto-assigns when DHCP fails

Watch out for

Common Network Configuration Concepts exam traps

  • Confusing static IP with DHCP reservation
  • Forgetting default gateway is needed for internet access
  • Mixing up DNS and DHCP server roles
  • Assuming subnet mask is always 255.255.255.0

A small office has a single router with four LAN ports. The network uses the 192.168.1.0/24 subnet, and the router's LAN IP is 192.168.1.1. A technician needs to add a new printer that must have a static IP address outside the DHCP range (192.168.1.100-192.168.1.200) but still be reachable by all devices. Which IP address should the technician assign to the printer?

A customer reports that their laptop connects to the office Wi-Fi but cannot access the internet. Other devices on the same network work fine. The technician checks the laptop's IP configuration and sees an IP address of 169.254.15.22. What is the most likely cause of this issue?

A network administrator is configuring a small business network with two subnets: 192.168.1.0/24 for employees and 192.168.2.0/24 for guests. The router has two LAN interfaces with IPs 192.168.1.1 and 192.168.2.1. A technician connects a new access point to the guest subnet switch and configures it with a static IP of 192.168.2.50. The access point can ping the router's guest interface but cannot reach the internet. The router's default route points to an ISP modem at 203.0.113.1. What is the most likely missing configuration?

A technician is troubleshooting a connectivity issue where a user's computer can ping the default gateway but cannot access a web server at 203.0.113.50. The technician runs a tracert and sees that the first hop responds, but subsequent hops time out. What is the most likely cause?

Question 6mediummultiple choice

A company's network uses a /24 subnet mask. The IT manager asks a technician to configure a new server with a static IP address of 192.168.1.300. The technician knows this is invalid. What is the reason this IP address cannot be used?

A user complains that their desktop computer cannot connect to any network shares, but they can access the internet. The technician pings the file server by IP address successfully, but pinging by hostname fails. Which network configuration issue is most likely causing this problem?

Question 8hardmultiple choice

A technician is troubleshooting a slow network connection for a user. The user's computer has an IP address of 192.168.1.100, subnet mask 255.255.255.0, and default gateway 192.168.1.1. The technician runs a ping to the gateway and gets replies with times around 2ms. However, pinging a server at 192.168.1.200 results in times over 500ms. The technician checks the switch and finds that the port for the user's computer is set to 10 Mbps half-duplex, while the computer's NIC is set to auto-negotiation. What is the most likely cause of the high latency?

A user reports that their laptop can connect to the corporate Wi-Fi but cannot access any network resources. The technician checks the IP configuration and sees an IP address of 192.168.1.105 with a subnet mask of 255.255.255.0 and a default gateway of 192.168.1.1. The technician pings the gateway successfully but cannot ping a server at 192.168.2.10. What is the most likely issue?

A technician is troubleshooting a network where users report intermittent connectivity. The technician finds that the switch logs show excessive CRC errors on multiple ports connected to different workstations. What is the most likely cause of these errors?

A user reports that their computer cannot connect to a network share. The technician runs ipconfig and sees an IP address of 169.254.1.5. What is the most likely cause?

A technician is setting up a new wireless network for a small office. The office has three access points (APs) that should allow seamless roaming. The technician configures all APs with the same SSID and security settings. What additional configuration is necessary to prevent clients from staying connected to a weak signal?

During a network upgrade, a technician replaces an old 10/100 Mbps switch with a new gigabit switch. After the change, several users report that their internet connection is slow. The technician checks the switch and sees that some ports show 100 Mbps instead of 1000 Mbps. What is the most likely cause?
