220-1201 Practice Test 8 — 10 Questions

Question 1

A technician is setting up a new file server and wants to ensure that clients can automatically obtain the server's IP address via a friendly name without manual configuration. Which network service should be configured on the server?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

DNS. DNS (Domain Name System) resolves friendly hostnames (e.g., fileserver.company.local) to IP addresses, allowing clients to automatically discover the server without manual IP entry. DHCP assigns IP addresses dynamically, but does not provide name resolution; DNS is the correct service for mapping names to IPs.

Answer

DHCP

Answer

RADIUS

Answer

NTP

Question 2

A technician is configuring a network for a new branch office. The branch has 50 users and needs to access resources at the main office via a secure tunnel over the internet. Which service is required to establish this connection?

Accepted Answer

VPN. A VPN (Virtual Private Network) is required to create a secure, encrypted tunnel over the internet between the branch office and the main office. This allows the 50 users to access internal resources at the main office as if they were on the same local network, using protocols such as IPsec or SSL/TLS to ensure confidentiality and integrity of data in transit.

Answer

DHCP

Answer

DNS

Answer

NAT

Question 3

A user reports that their laser printer prints pages with a repeating horizontal band of missing text about every 3 inches. The printer has a new toner cartridge and the drum is separate. What is the most likely cause?

Accepted Answer

The drum unit has a scratch or defect. A repeating horizontal defect at a fixed interval (here, every 3 inches) is the classic signature of a physical defect on a rotating component whose circumference matches that interval — most commonly the drum unit. Since the drum is separate from the toner cartridge and the toner is new, the scratch or debris on the drum surface is the most likely cause.

Answer

The fuser is not reaching the correct temperature

Answer

The toner cartridge is defective

Answer

The paper is damp or of poor quality

Question 4

You are deploying a new VoIP phone and need to ensure the Ethernet cable from the wall jack to the phone is properly terminated and has no shorts. The cable appears to be wired correctly but you want to confirm. Which tool should you use?

Accepted Answer

Cable tester. A cable tester verifies continuity, pin-to-pin wiring, and detects shorts or opens in an Ethernet cable. Since the question states the cable appears correctly wired but you need to confirm proper termination and absence of shorts, the cable tester is the correct tool for this passive copper cable validation.

Answer

Toner probe

Answer

Loopback plug

Answer

Multimeter

Question 5

A technician is troubleshooting a network where users on one floor cannot communicate with users on another floor. Both floors are connected to the same switch via separate VLANs configured for security. What additional device is needed to allow communication between the VLANs?

Accepted Answer

A router or Layer 3 switch. VLANs segment a Layer 2 network into separate broadcast domains, so hosts in different VLANs cannot communicate at Layer 2. To route traffic between VLANs, you need a Layer 3 device — either a router (with subinterfaces or separate physical interfaces) or a Layer 3 switch (with SVIs). This is the classic 'router-on-a-stick' or inter-VLAN routing scenario.

Answer

A hub

Answer

A Layer 2 switch

Answer

A bridge

Question 6

A customer complains that their web browser cannot load any HTTPS websites, but HTTP sites work fine. The firewall is configured to allow common ports. Which port is most likely being blocked?

Accepted Answer

443. HTTPS uses TCP port 443 for encrypted communication via TLS/SSL. If HTTP (port 80) works but HTTPS fails, the firewall is likely blocking outbound or inbound traffic on port 443, even though it allows common ports. This prevents the browser from establishing the secure connection required for HTTPS websites.

Answer

80

Answer

22

Answer

53

Question 7

After updating the firmware on a workstation, the system fails to boot and displays a 'Boot Device Not Found' error. The hard drive is detected in UEFI settings. What is the most likely cause?

Accepted Answer

The boot mode changed from Legacy to UEFI (or vice versa). A firmware update can reset or change the UEFI/BIOS boot mode setting, causing the system to look for an EFI System Partition (ESP) when the OS was installed in Legacy/CSM mode, or vice versa. Since the drive is detected in UEFI settings, the hardware is fine — the mismatch between the configured boot mode and the installed bootloader is the most likely cause of 'Boot Device Not Found.'

Answer

The hard drive has failed due to the update

Answer

Secure Boot is blocking the bootloader

Answer

The CMOS battery needs replacement

Question 8

A company's web server is hosted internally and must be accessible from the internet using the domain name www.company.com. The public IP address of the router is 203.0.113.5. Which two network services must be correctly configured to make this work?

Accepted Answer

DNS and NAT. DNS is required to resolve the domain name www.company.com to the public IP address 203.0.113.5, so external users can reach the router. NAT (specifically destination NAT or port forwarding) is needed to translate the public IP and port to the internal private IP address of the web server, allowing inbound traffic to reach the internal host.

Answer

DNS and DHCP

Answer

NAT and ARP

Answer

DHCP and NAT

Question 9

A user reports that their computer cannot access any network resources, but the link light on the NIC is solid. The technician suspects a faulty cable. Which tool can quickly test the cable's continuity and detect a broken wire?

Accepted Answer

Cable tester. A cable tester sends a small electrical signal through each conductor in the cable and checks for a return signal on the correct pin. If a wire is broken, the tester will indicate an open circuit, confirming the fault. This is the fastest and most direct way to verify continuity in a copper Ethernet cable.

Answer

Multimeter

Answer

Toner and probe

Answer

Crimper

Question 10

A network administrator is designing a new subnet scheme for a company with 4 departments: Sales (50 devices), HR (25 devices), IT (10 devices), and Management (5 devices). The company uses the 10.0.0.0/8 network. To minimize wasted IP addresses, which subnet mask should be used for the Sales department?

Accepted Answer

255.255.255.192. The Sales department requires 50 usable IP addresses. A /26 subnet mask (255.255.255.192) provides 64 total addresses, with 62 usable addresses (2^6 - 2 = 62), which is the smallest subnet that can accommodate 50 devices without wasting IPs. This aligns with the goal of minimizing wasted addresses in the 10.0.0.0/8 network.

Answer

255.255.255.0

Answer

255.255.255.224

Answer

255.255.255.240
