CompTIA 220-1201 Practice Test 1
Question 1
On a service ticket for Amberline Finance, the team observes: A workstation reaches a thermal limit seconds after a cooler was replaced. The supporting record states that the heat sink was not firmly fastened and the thermal interface compound was omitted. The desired outcome is to restore reliable heat transfer from the processor to its cooling assembly. Service work must follow power isolation, ESD, and manufacturer instructions when applicable. Which acceptance result best demonstrates the issue is resolved?
- Verify signed media boot and unsigned test boot is rejected by policy
- Verify improved access latency and acceptable write endurance for the workload
- Verify sustained workload temperatures stay within processor limits and throttling ceases
- Verify CPU identity, temperature and stability under a controlled load
Explanation
Correct Answer
C:
Verify sustained workload temperatures stay within processor limits and throttling ceases. It proves the required function with an observable result instead of assuming the change worked. The relevant observation is that the heat sink was not firmly fastened and the thermal interface compound was omitted. The support goal is to restore reliable heat transfer from the processor to its cooling assembly; this validate action specifically addresses cpu heatsink thermal interface without confusing a different subsystem.
Incorrect Answers
A:
Verify signed media boot and unsigned test boot is rejected by policy. This action is appropriate for uefi secure boot versus boot order, normally when a laptop can start a trusted OS but prompts when an unsigned bootloader is inserted. Here the observed facts require cpu heatsink thermal interface instead.
B:
Verify improved access latency and acceptable write endurance for the workload. This action is appropriate for ssd versus hdd latency and interface, normally when a mobile user needs low-latency storage and shock resistance but a procurement request specifies a 5400 RPM hard disk. Here the observed facts require cpu heatsink thermal interface instead.
D:
Verify CPU identity, temperature and stability under a controlled load. This action is appropriate for cpu socket matching motherboard, normally when a gaming PC has a motherboard with an AMD processor socket but an Intel CPU was ordered. Here the observed facts require cpu heatsink thermal interface instead.
Question 2
At Maplebank Ltd, a technician working in small-office network service desk identifies this issue: A SOHO laptop automatically assigns itself 169.254.42.19 with a 255.255.0.0 mask. The supporting record states that the network uses DHCP but the laptop has not received a valid lease from the local server. The desired outcome is to recognize IPv4 link-local APIPA as a DHCP reachability symptom. Service work must follow power isolation, ESD, and manufacturer instructions when applicable. What should the technician recommend as the corrective approach?
- Repair the DNS server or client DNS setting rather than rebuilding the DHCP address pool
- Configure the reachable 192.168.10.1 gateway on the office client
- Use supported WPA3-Personal or appropriate WPA2-AES compatibility with strong credentials and retire WEP
- Restore correct DHCP reachability rather than treating the APIPA address as a routable internet address
Explanation
Correct Answer
D:
Restore correct DHCP reachability rather than treating the APIPA address as a routable internet address. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that the network uses DHCP but the laptop has not received a valid lease from the local server. The support goal is to recognize IPv4 link-local APIPA as a DHCP reachability symptom; this design action specifically addresses apipa 169.254.x.x missing dhcp lease without confusing a different subsystem.
Incorrect Answers
A:
Repair the DNS server or client DNS setting rather than rebuilding the DHCP address pool. This action is appropriate for dns resolution versus dhcp address assignment, normally when a workstation has a valid IPv4 address, gateway and lease but cannot reach services by hostname. Here the observed facts require apipa 169.254.x.x missing dhcp lease instead.
B:
Configure the reachable 192.168.10.1 gateway on the office client. This action is appropriate for ipv4 subnet mask and gateway selection, normally when a small office workstation has 192.168.10.80/24 and a gateway incorrectly set to 192.168.11.1. Here the observed facts require apipa 169.254.x.x missing dhcp lease instead.
C:
Use supported WPA3-Personal or appropriate WPA2-AES compatibility with strong credentials and retire WEP. This action is appropriate for soho wireless wpa security setup, normally when a small office access point still allows WEP while newer managed clients support WPA3-Personal. Here the observed facts require apipa 169.254.x.x missing dhcp lease instead.
Question 3
During Pioneer Markets's branch networking support, the technician encounters this condition: A clinic has a lobby wireless network and teleworkers, requiring isolation plus encrypted access.

Here the observed facts require vlan segmentation versus vpn encrypted tunneling instead.
C:
Deploy an appropriate load balancer with health probes for the supported service. This action is appropriate for load balancer versus proxy server functions, normally when a web service needs requests distributed across three application servers with failed nodes removed automatically. Here the observed facts require vlan segmentation versus vpn encrypted tunneling instead.
D:
Correct MX routing to the active mail service without treating SPF as an incoming delivery address. This action is appropriate for mx and spf dns records distinct purposes, normally when a domain receives email at the wrong destination after DNS changes. Here the observed facts require vlan segmentation versus vpn encrypted tunneling instead.
Question 4
On a service ticket for Fountain Transport, the team observes: Staff use personally owned phones to read corporate mail but refuse full device enrollment. The supporting record states that the employer needs to protect work app data while leaving personal photos and apps outside corporate control. The desired outcome is to apply supported corporate application controls with appropriate privacy scope. The technician must document observations separately from assumptions. How should the solution first be tested on an approved spare or pilot system?
- Pilot managed work apps with a consented BYOD phone and an unprotected personal app
- Create one harmless test appointment and synchronize through the chosen enterprise account
- Restore a non-sensitive test backup to the new SSD and verify recovery-key retrieval in a controlled service workflow
- Activate the eSIM on a spare enrolled phone using an approved carrier test profile
