220-1101 Networking Practice Test 14 — 15 Questions

Question 1

A user reports that they cannot access the company intranet website at http://intranet. The technician opens a browser on the workstation and types the IP address 192.168.10.5, which successfully loads the intranet page. The workstation is configured to obtain IP settings automatically via DHCP. Which of the following is the MOST likely cause of the issue?

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

Accepted Answer

The DHCP server is not providing a DNS server address. The user can access the intranet by IP address but not by hostname, which indicates a name resolution failure. Since the workstation uses DHCP, the most likely cause is that the DHCP server is not providing a DNS server address, so the browser cannot resolve 'intranet' to an IP. This is a classic symptom of missing or misconfigured DNS settings from DHCP.

Answer

The intranet server is down

Answer

The workstation has a corrupted hosts file

Answer

The workstation's browser cache is full

Question 2

A technician is configuring a small office network with a managed switch. A new employee's workstation is connected to port 12 on the switch. The workstation receives an IP address from the DHCP server and can ping the default gateway (192.168.1.1), but it cannot ping the file server at 192.168.1.50. Other workstations on the same subnet can ping the file server. The technician checks the switch configuration and sees that port 12 is assigned to VLAN 10, while all other workstations and the file server are on VLAN 1. Which of the following is the MOST likely reason the workstation cannot reach the file server?

Accepted Answer

The switch port is configured as an access port in the wrong VLAN. The workstation is on VLAN 10 while the file server and other workstations are on VLAN 1. By default, VLANs segment broadcast domains and isolate Layer 2 traffic; a device on VLAN 10 cannot communicate with a device on VLAN 1 unless a Layer 3 device (router or Layer 3 switch) routes between them. Since the switch port is configured as an access port in VLAN 10, it is the wrong VLAN assignment that prevents the workstation from reaching the file server.

Answer

The workstation's subnet mask is incorrect

Answer

The workstation's firewall is blocking traffic

Answer

The DHCP server assigned an IP from a different scope

Question 3

A technician is setting up a new workstation. After connecting the Ethernet cable, the link light on the NIC and the switch port are solid green. The technician runs ipconfig and sees an IP address of 169.254.3.45 with a subnet mask of 255.255.0.0. The workstation cannot ping the default gateway or any other network devices. Which of the following is the MOST likely cause?

Accepted Answer

The DHCP server is unavailable or unreachable. The 169.254.x.x address with a /16 subnet mask is an Automatic Private IP Addressing (APIPA) address, assigned by Windows when a DHCP server is unreachable. The solid link lights confirm Layer 1 connectivity is good, so the issue is that the workstation cannot obtain a valid IP from a DHCP server, preventing communication with the default gateway.

Answer

The Ethernet cable is faulty

Answer

The workstation's subnet mask is incorrect

Answer

The NIC driver is corrupted

Question 4

A technician connects a new workstation to a managed switch port. The workstation receives an IP address from the DHCP server and can ping its own IP address, but it cannot ping any other devices on the local network, including the default gateway. The technician verifies that the Ethernet cable is functional and that the link lights are solid on both the NIC and the switch port. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The switch port is configured with an incorrect VLAN assignment.. The workstation receives an IP address and can ping itself, confirming Layer 3 configuration is functional. However, it cannot ping other devices on the local network, including the default gateway. Since the cable and link lights are good, the issue is at Layer 2. An incorrect VLAN assignment on the switch port isolates the workstation into a different broadcast domain, preventing it from communicating with devices in the correct VLAN, including the gateway.

Answer

The workstation's network adapter is set to half-duplex.

Answer

The DHCP server has excluded the workstation's MAC address.

Answer

The default gateway is not configured on the switch.

Question 5

A user reports that they can browse the internet and receive emails but cannot send emails using their email client. The email client is configured to use the company's email server. The technician verifies that other users in the same office can send and receive emails without any issues. The workstation's software firewall is disabled. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The email client's outgoing server settings are misconfigured.. Since the user can receive emails (POP3/IMAP) and browse the internet, network connectivity and DNS resolution are functional. The fact that other users can send emails confirms the SMTP service on the server is operational. The most likely cause is that the email client's outgoing server settings (SMTP server address, port, or authentication) are misconfigured, preventing the client from establishing an SMTP session to relay the outgoing message.

Answer

The email server's SMTP service is experiencing an outage.

Answer

The workstation's DNS resolver cannot resolve the email server's hostname.

Answer

The user's email account password has expired.

Question 6

A workstation has an APIPA address beginning with 169.254 after being moved to a new office. Other users in the office can access the network. What is the most likely issue?

Accepted Answer

The workstation did not receive an address from DHCP. The APIPA address (169.254.x.x) is automatically assigned by the operating system when a DHCP server is unreachable. Since other users in the office can access the network, the DHCP server is functioning, so the issue is specific to this workstation's inability to obtain a DHCP lease—likely due to a faulty cable, port, or NIC configuration.

Answer

The printer driver is missing

Answer

The monitor refresh rate is unsupported

Answer

DNS resolution is working normally

Question 7

A user has link lights on a network port but receives very slow file transfers. The switch reports many CRC errors on the port. What is the most likely cause?

Accepted Answer

Faulty or damaged Ethernet cable. CRC errors indicate that frames are being corrupted during transmission, which is a classic symptom of a faulty or damaged Ethernet cable. A damaged cable can cause signal degradation, leading to bit errors that the switch detects as CRC mismatches, resulting in retransmissions and slow file transfers.

Answer

Unsupported paper size

Answer

Expired user password

Answer

Incorrect default gateway only

Question 10

Match each RAID level to its description.

Accepted Answer

RAID 0: Stripes data across multiple disks for increased performance, no fault tolerance.. RAID levels define how data is distributed across drives. RAID 0 focuses on performance, RAID 1 on mirroring, and RAID 5 on striping with parity. Common confusions arise from swapping these characteristics.

Answer

RAID 1: Stripes data across multiple disks for increased performance, no fault tolerance.

Answer

RAID 5: Mirrors data onto two disks for redundancy.

Answer

RAID 0: Stripes data with parity for redundancy.

Question 11

Match each printer type to its technology.

Accepted Answer

Laser: Uses toner and fuser to bond powder to paper. Laser printers use toner and fuser; inkjet printers spray liquid ink; dot matrix printers use pins and ribbon; thermal printers use heat. Common confusions include mixing laser and thermal transfer or swapping laser and inkjet technologies.

Answer

Laser: Uses heat to melt wax onto paper

Answer

Inkjet: Uses toner and fuser

Question 12

A technician is configuring a SOHO router for a small business. The business needs to allow inbound Remote Desktop Protocol (RDP) traffic to a single internal server at 192.168.1.50. The router's public IP is 203.0.113.10. Which of the following should the technician configure?

Accepted Answer

Port forwarding for TCP 3389 to 192.168.1.50. Port forwarding allows external devices to reach a specific internal service by mapping a public port to an internal IP and port. RDP listens on TCP 3389, so forwarding that port to the server's IP enables remote access without exposing all ports. Port triggering, DMZ, and static NAT are either insecure, impractical, or incorrect for this scenario.

Answer

Port triggering for TCP 3389 to 192.168.1.50

Answer

Static NAT for 192.168.1.50

Answer

DMZ host configuration for 192.168.1.50

Question 13

A network administrator is configuring a DHCP scope on a Windows Server for a new subnet. The administrator wants to ensure that a specific printer always receives the same IP address without manually configuring the printer. Which of the following should be used?

Accepted Answer

DHCP reservation. A DHCP reservation ensures a device always receives the same IP by mapping its MAC address to a specific address. This meets the requirement of no manual configuration on the printer while providing consistency. Static IP, exclusion range, and longer leases do not achieve the same centralized, automatic guarantee.

Answer

Exclusion range

Answer

Static IP configuration on the printer

Answer

Longer lease duration

Question 14

A technician is troubleshooting a network issue where a user can access websites by IP address but not by domain name. The technician runs ipconfig /all and sees that the DNS server is set to 192.168.1.1, which is the router. The router's DNS settings are correct. Which of the following commands should the technician use to test DNS resolution on the workstation?

Accepted Answer

nslookup. nslookup is the tool designed to query DNS servers and verify name resolution. Since the user can access websites by IP but not by name, DNS is the likely culprit. Running nslookup will show if the DNS server is responding and resolving correctly, helping to pinpoint the issue.

Answer

tracert

Answer

ipconfig /flushdns

Answer

ping

Question 15

A technician is setting up a wireless network for a small business using a consumer-grade wireless router. The business needs to support both older laptops that only support 2.4 GHz and newer devices that support 5 GHz. The technician wants to ensure that both frequency bands are available and that the network is secure. Which of the following should the technician configure? (Choose two.)

Accepted Answer

Enable both 2.4 GHz and 5 GHz radios on the router.. To support both older 2.4 GHz-only laptops and newer 5 GHz devices, the technician must enable both radios. For security, WPA2-Personal with AES is compatible with the widest range of devices while providing robust encryption. These two configurations ensure that all devices can connect securely without compatibility issues.

Answer

Disable SSID broadcast to hide the network.

Answer

Set the same SSID and security settings on both bands.

Answer

Configure WPA3 security on the 5 GHz band and WPA2 on the 2.4 GHz band.
