Question 2

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?

Accepted Answer

192.168.1.50. (192.168.1.50) is correct because it falls within the 192.168.1.0/24 subnet, is outside the DHCP range of 192.168.1.100–200, and is on the same broadcast domain as all devices, ensuring reachability without an IP conflict.

Answer

192.168.1.150

Answer

10.0.0.50

Answer

192.168.2.50

Question 3

A technician is installing a new SSD into a customer's laptop. After removing the bottom cover, they see the existing hard drive is held in place by a metal bracket and a single screw. What is the correct next step?

Accepted Answer

Remove the screw and bracket, then gently lift the drive out of the SATA connector.. The correct next step is to remove the screw and bracket, then gently lift the drive out of the SATA connector. This is because the metal bracket secures the drive in place, and the SATA connector is a fragile, keyed interface that requires a straight, gentle pull to avoid damaging the pins or the drive's edge connector. Forcing the drive or prying it can bend pins or crack the connector.

Answer

Pull the drive straight out with force to disconnect it.

Answer

Use a plastic spudger to pry the drive from the connector.

Answer

Remove the battery first to avoid electrical shock.

Accepted Answer

The calendar app needs to be re-authorized for the Exchange account.. This scenario focuses on app-specific sync issues after an OS update. The most common cause is that the app's permissions or account settings were reset during the update, requiring re-authorization or re-configuration of the Exchange account within the calendar app.

Answer

The Exchange server is down.

Answer

The iOS update removed the Exchange account from the device.

Answer

The calendar app is corrupted and must be reinstalled.

Question 8

A user reports that their new high-resolution monitor (2560x1440) connected via DisplayPort shows intermittent black screens for a few seconds. The monitor works fine at lower resolutions. What is the most likely issue?

Accepted Answer

The DisplayPort cable is not certified for the required bandwidth. The most likely issue is that the DisplayPort cable is not certified for the required bandwidth. At 2560x1440 resolution, the monitor requires a high data rate (approximately 7.04 Gbps for 60 Hz), and a non-certified or low-quality cable may not reliably support this bandwidth, causing intermittent signal loss and black screens. Lower resolutions work because they require less bandwidth, allowing the cable to function within its limits.

Answer

The monitor's power saving mode is too aggressive

Answer

The graphics card is overheating

Answer

The monitor's firmware is outdated

Question 9

A customer reports that their desktop PC will not power on at all. The power supply fan does not spin, and no LEDs are lit. You have verified the power cord is good and the outlet has power. Which motherboard component should you check first?

Accepted Answer

The 24-pin ATX power connector. The ATX power connector (main power connector) supplies power from the PSU to the motherboard. If it is loose or disconnected, the motherboard will not receive power, causing a no-power condition. Always check this first before assuming PSU failure.

Answer

The CMOS battery

Answer

The front panel power switch header

Answer

The CPU fan header

Question 10

A company deploys several tablets for field technicians that need to connect to a private LTE network via a SIM card. One tablet connects to the network but has very slow data speeds. Other tablets in the same area work fine. What is the most likely cause?

Accepted Answer

The tablet is using the wrong APN configuration.. The most likely cause is an incorrect APN configuration. The APN (Access Point Name) defines the gateway between the LTE network and the internet, including required authentication and IP settings. If the APN is wrong, the tablet may still attach to the LTE network but will experience severely degraded data throughput because the packet data protocol (PDP) context cannot establish a proper data session.

Answer

The tablet's Wi-Fi is interfering with the LTE signal.

Answer

The tablet's SIM card is not fully inserted.

Answer

The tablet's battery saver mode is enabled.

Question 11

A user reports that their iPad's Safari browser crashes immediately upon opening, but other apps work fine. They have already restarted the device. What should the technician do next?

Accepted Answer

Clear Safari's history and website data in Settings.. Clearing Safari's history and website data removes corrupted cached files, cookies, or local storage data that can cause the browser to crash on launch. Since other apps work fine, the issue is isolated to Safari's stored data, not the entire system. This is the recommended first troubleshooting step for a single-app crash after a restart.

Answer

Perform a factory reset on the iPad.

Answer

Update iOS to the latest version.

Answer

Disable all Safari extensions.

Question 12

A company's remote employees use VPN to connect to the office network. Recently, some users report that they can connect to the VPN but cannot browse the internet or access internal servers by name, though they can ping internal IP addresses. The VPN is configured to push DNS settings. Which protocol is likely misconfigured on the VPN server?

Accepted Answer

DNS. (DNS) because the users can connect to the VPN and ping internal IP addresses, but cannot resolve hostnames to IP addresses. This indicates that the DNS resolution is failing, which is caused by the VPN server not correctly pushing DNS server settings to the VPN clients. Without proper DNS configuration, clients cannot translate domain names (e.g., internal server names or internet URLs) into IP addresses, even though the network layer connectivity (ping to IPs) works.

Answer

DHCP

Answer

IPsec

Answer

SSL/TLS

Question 13

A customer reports that their wireless printer stops responding when the microwave is in use. The printer is connected via Wi-Fi to a dual-band router. Which troubleshooting step should the technician take first to resolve this issue?

Accepted Answer

Connect the printer to the 5 GHz network. The microwave oven operates in the 2.4 GHz ISM band, generating broadband interference that disrupts Wi-Fi communication on that frequency. Connecting the printer to the 5 GHz network avoids this interference entirely because the 5 GHz band is not affected by microwave emissions, providing a clean channel for the printer.

Answer

Replace the printer with a wired model

Answer

Change the router’s 2.4 GHz channel

Answer

Update the printer firmware

Question 14

A network administrator notices that a managed switch is not reporting its status to the central monitoring system. The monitoring system uses a protocol that collects device information such as CPU load and interface errors. Which protocol is most likely not configured on the switch?

Accepted Answer

SNMP. SNMP (Simple Network Management Protocol) is the standard protocol used by network monitoring systems to collect device information such as CPU load, interface errors, and uptime. If the managed switch is not reporting to the central monitoring system, SNMP is most likely not configured or its community strings are misconfigured, preventing the monitoring server from polling the switch.

Answer

Question 15

A company uses a cloud-based virtual desktop infrastructure (VDI) solution. Users report that logging in takes 5 minutes during peak hours. The IT team notices that the cloud provider's resource utilization is at 95%. Which action would best resolve this issue?

Accepted Answer

Scale out by adding more virtual desktops. When a cloud provider's resource utilization is at 95%, the underlying physical infrastructure is saturated. Scaling up (vertical scaling) increases the VM's resources but does not alleviate the host-level bottleneck; the provider may not allow further scaling. Scaling out (horizontal scaling) adds more virtual desktop instances, distributing the load across additional VMs and reducing login times. Migrating providers is disruptive, and disabling auto-scaling worsens performance.

Answer

Migrate to a different cloud provider

Answer

Scale up the virtual machines by increasing CPU and RAM

Answer

Disable automatic scaling
