220-1201 Practice Test 41 — 15 Questions

Question 1

A company's network uses a managed switch with VLANs. Users in VLAN 10 can ping the default gateway but cannot communicate with users in VLAN 20. The switch is connected to a router that handles inter-VLAN routing. What is the most likely misconfiguration?

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

Accepted Answer

The switch port connecting to the router is configured as an access port instead of a trunk.. The most likely misconfiguration is that the switch port connecting to the router is configured as an access port instead of a trunk. For inter-VLAN routing to work, the router must receive traffic from multiple VLANs on the same physical interface. A trunk port (using 802.1Q tagging) allows frames from VLAN 10 and VLAN 20 to be forwarded to the router, which then routes between them. An access port can only carry traffic for a single VLAN, so frames from VLAN 20 would be dropped or misdirected, preventing communication.

Answer

The router's firewall is blocking traffic between VLANs.

Answer

The default gateway for VLAN 20 is misconfigured.

Answer

The switch has Spanning Tree Protocol enabled, blocking the link.

Question 2

A network administrator is troubleshooting a connectivity issue between two servers. Server A has IP 192.168.10.25/25, and Server B has IP 192.168.10.200/25. Server A can ping its default gateway (192.168.10.1) but cannot ping Server B. What is the most likely cause?

Accepted Answer

The servers are on different subnets and require a router to communicate.. Server A (192.168.10.25/25) has a subnet mask of 255.255.255.128, placing it in the 192.168.10.0/25 subnet (range 0–127). Server B (192.168.10.200/25) is in the 192.168.10.128/25 subnet (range 128–255). These are different subnets, so Server A cannot reach Server B directly via Layer 2; a router (or Layer 3 switch) is required to forward traffic between them. The fact that Server A can ping its default gateway (192.168.10.1) confirms its IP and mask are correctly configured for its own subnet.

Answer

Server A has a duplicate IP address.

Answer

The subnet mask is incorrect on one of the servers.

Answer

The default gateway is misconfigured.

Question 3

A technician is setting up internet for a rural home that is 5 miles from the nearest town. The home has no cable TV or phone line. Which internet connection type is most feasible?

Accepted Answer

Satellite. Satellite internet is the most feasible option because the home is 5 miles from the nearest town with no cable TV or phone line infrastructure. Satellite requires only a clear line of sight to the sky, making it independent of terrestrial cabling. Cable broadband, DSL, and fiber optic all depend on physical infrastructure (coaxial cable, twisted-pair copper, or fiber) that does not extend to this remote location.

Answer

Cable broadband

Answer

DSL

Answer

Fiber optic

Question 4

A technician is setting up a new file server and needs to assign it a static IP address. The network uses a subnet of 192.168.1.0/24, and the router's LAN IP is 192.168.1.1. The technician wants to ensure the server is reachable from all devices on the local network. Which of the following IP addresses should the technician assign to the server?

Accepted Answer

192.168.1.50. (192.168.1.50) is correct because it falls within the usable host range of the 192.168.1.0/24 subnet (192.168.1.1 to 192.168.1.254) and is not reserved for the network address or broadcast address. Assigning this static IP ensures the server is reachable from all devices on the local network, as it is on the same subnet as the router's LAN IP (192.168.1.1).

Answer

192.168.1.0

Answer

192.168.1.255

Answer

192.168.2.1

Question 5

A user reports that their internet connection drops out frequently, especially during rainstorms. They have a dish mounted on their roof. Which connection type are they most likely using?

Accepted Answer

Satellite. Satellite internet (Option C) is the correct answer because the user's dish is mounted on the roof, and the connection drops out during rainstorms—a phenomenon known as 'rain fade.' Rain attenuates the Ku-band or Ka-band radio frequencies (typically 12–18 GHz or 26–40 GHz) used by satellite systems, causing signal loss. Fiber-optic, cable, and DSL are terrestrial connections that do not use a roof-mounted dish and are not significantly affected by rain.

Answer

Fiber-optic

Answer

Cable broadband

Answer

DSL

Question 6

During a routine printer maintenance, you replace the toner cartridge in a laser printer. After reassembly, the printer displays 'Replace Toner' error even though the new cartridge is installed. What should you do first?

Accepted Answer

Remove the protective seal and reseat the cartridge. The 'Replace Toner' error after installing a new cartridge often means the cartridge is not properly seated or the protective seal was not removed. Removing the seal allows toner to flow, and reseating ensures the printer detects the cartridge correctly.

Answer

Replace the fuser assembly

Answer

Clean the corona wire

Answer

Update the printer firmware

Question 7

A school district with five elementary schools spread across a city needs to connect each school's LAN to a central data center for internet access and shared resources. Which network type should connect the schools to the data center?

Accepted Answer

Metropolitan Area Network (MAN). A Metropolitan Area Network (MAN) is designed to interconnect multiple LANs across a city or metropolitan region, typically using high-speed fiber optic links such as Metro Ethernet or SONET/SDH. This makes it the ideal choice for connecting five elementary schools spread across a city to a central data center, as it covers a larger geographic area than a LAN but is more localized than a WAN.

Answer

Local Area Network (LAN)

Answer

Wide Area Network (WAN)

Answer

Personal Area Network (PAN)

Question 8

A network administrator needs to determine the exact model and firmware version of a switch located in a remote wiring closet without physically visiting the site. The switch is configured with an IP address on the management VLAN. Which tool can be used to query the switch's SNMP agent for this information?

Accepted Answer

SNMP management tool. An SNMP management tool can query the switch's SNMP agent using GET requests to retrieve the exact model and firmware version from the system MIB (RFC 1213), specifically the sysDescr (1.3.6.1.2.1.1.1) and sysObjectID (1.3.6.1.2.1.1.2) OIDs. This allows remote, agent-based access without physical site visits, as the switch is reachable via its management VLAN IP address.

Answer

Packet analyzer (e.g., Wireshark)

Answer

Port scanner (e.g., Nmap)

Answer

Wi-Fi analyzer

Question 9

During a network upgrade, you need to identify which cable in a messy patch panel corresponds to a specific office wall jack. The cables are not labeled. Which tool should you use?

Accepted Answer

Toner probe. A toner probe (inductive amplifier and tone generator) is the correct tool for tracing an unlabeled cable from a patch panel to a specific wall jack. The tone generator injects a distinctive audio signal onto the wire pair, and the inductive probe detects that signal without requiring a direct electrical connection, allowing you to identify the correct cable even in a dense, messy bundle.

Answer

Cable tester

Answer

Multimeter

Answer

Loopback plug

Question 10

A technician is troubleshooting a network drop that was working yesterday but now has no link light. The cable run is 90 meters and uses Cat5e. The patch cables and switch ports have been tested and are fine. What is the most likely issue?

Accepted Answer

The cable has been cut or damaged.. Since the cable run is 90 meters (within the 100-meter maximum for Cat5e), the patch cables and switch ports are verified working, and the link light is absent, the most likely cause is physical damage to the cable—such as a cut, pinch, or break—that interrupts the electrical continuity required for link pulses. A damaged cable prevents the switch and NIC from establishing a link, even if all other components are functional.

Answer

The cable is too long for Cat5e.

Answer

The network switch is not powered on.

Answer

The cable is terminated with the wrong standard.

Question 11

During a hardware installation, you are tasked with setting up a RAID 1 array in a server using two identical 4 TB HDDs. After configuration, the total usable capacity is only 4 TB. Is this expected behavior?

Accepted Answer

Yes, RAID 1 provides fault tolerance by mirroring data, so usable capacity is 4 TB.. RAID 1 mirrors data across two drives, so usable capacity equals the size of one drive (4 TB). This provides redundancy, not increased storage. RAID 0 would combine capacity, and RAID 5 requires at least three drives.

Answer

No, the array should show 8 TB because the drives are identical.

Answer

No, the array should be configured as RAID 0 to get 8 TB.

Answer

Yes, but only if the drives are set as JBOD.

Question 12

A user reports that their Android phone will not install an app from the Google Play Store. The device has plenty of storage space and a strong internet connection. What is the most likely cause of this issue?

Accepted Answer

The device's operating system version is too old for the app.. The most likely cause is that the device's operating system version is too old for the app. Android apps specify a minimum API level (minSdkVersion) in their manifest; if the device runs an older OS version below that threshold, Google Play Store will block the installation and display an incompatibility message. Since the user has plenty of storage and a strong connection, the OS version is the primary remaining constraint.

Answer

The app is not compatible with the device's screen resolution.

Answer

The Google Play Store app needs to be reinstalled.

Answer

The user is not signed into their Google account.

Question 13

A user reports that their iPhone will not connect to a Bluetooth speaker that is in pairing mode. The speaker is listed in the iPhone's Bluetooth settings but tapping it does nothing. What should the technician try first?

Accepted Answer

Forget the speaker in Bluetooth settings and re-pair.. When a Bluetooth speaker is listed in the iPhone's settings but tapping it fails to connect, the most common cause is a corrupted pairing record. Selecting 'Forget This Device' removes the stored link key, forcing a fresh pairing handshake that re-establishes the correct encryption and service discovery. This is the first-line troubleshooting step because it directly addresses the stored connection state without affecting other network settings or requiring a device restart.

Answer

Restart the iPhone.

Answer

Reset the network settings on the iPhone.

Answer

Update the speaker's firmware.

Question 14

A technician is troubleshooting a network where users can access internal resources but cannot reach any external websites. The internal network uses a proxy server. The technician finds that the proxy server is configured to use a specific protocol to forward requests to the internet. Which protocol is the proxy server most likely using to communicate with external web servers?

Accepted Answer

HTTP. The proxy server is most likely using HTTP (Hypertext Transfer Protocol) to forward requests to external web servers. Since users are accessing internal resources but cannot reach external websites, the proxy server acts as an intermediary for web traffic. HTTP is the standard protocol for web communication, and proxy servers typically use HTTP (or HTTPS) to forward client requests to internet web servers, as it allows the proxy to cache, filter, and modify web traffic.

Answer

FTP

Answer

DNS

Answer

SNMP

Question 15

A technician is configuring a corporate iPhone for a new executive. The user needs to access company email, calendar, and contacts, but the company requires that all data be encrypted and the device be remotely wipeable. Which configuration step is essential?

Accepted Answer

Enable the device's passcode and Touch ID/Face ID.. Enabling the device's passcode and Touch ID/Face ID is essential because it activates hardware-backed encryption on iOS devices. Without a passcode, iOS cannot generate the encryption key required to protect data at rest, and remote wipe capabilities are contingent on the device being able to authenticate and enforce management commands. This step directly satisfies the corporate requirements for data encryption and remote wipeability.

Answer

Install a third-party antivirus app.

Answer

Disable iCloud backup for the device.

Answer

Set up a VPN connection for all traffic.
