A technician is troubleshooting a server that unexpectedly shut down. The server has redundant power supplies, and the building power is stable. The technician checks the BIOS event log and finds a thermal warning before shutdown. The server is in a rack with other servers, all within temperature range. Which of the following is the most likely cause?

A technician is troubleshooting a server that unexpectedly shut down. The server has redundant power supplies, and the building power is stable. The technician checks the BIOS event log and finds a thermal warning before shutdown. The server is in a rack with other servers, all within temperature range. Which of the following is the most likely cause?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

A failed power supply unit

The server has redundant power supplies and stable building power, so a PSU failure is unlikely to cause a thermal warning. PSU failure would typically result in a power loss event, not a temperature-related shutdown.

B

Best answer

Loose CPU heatsink

A loose heatsink prevents proper heat transfer from the CPU to the cooling fins, causing the CPU to overheat quickly even in a cool environment. The BIOS detects the temperature rise and issues a thermal warning before shutting down to prevent damage.

C

Distractor review

Incompatible RAM

Incompatible RAM typically causes boot failures, system instability, or errors, but does not generate excessive heat that would trigger a thermal warning and shutdown.

D

Distractor review

Hard drive failure

Hard drive failure usually results in data errors, boot failures, or unusual noises, not a thermal shutdown. Hard drives have their own temperature sensors, but a single drive failure would not cause a server-wide thermal warning.

Common exam trap

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Technical deep dive

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

  • Static NAT maps one inside address to one outside address.
  • PAT allows many inside hosts to share one public address using ports.
  • Inside local and inside global describe the private and translated addresses.
  • NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

  • Identify inside and outside interfaces first.
  • Check whether the scenario needs static NAT, dynamic NAT or PAT.
  • Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1

A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?

Question 2

A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)

Question 3

A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?

Question 4

A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?

Question 5

A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?

Question 6

A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?

FAQ

Questions learners often ask

What does this 220-1101 question test?

Static NAT maps one inside address to one outside address.

What is the correct answer to this question?

The correct answer is: Loose CPU heatsink — A thermal warning followed by shutdown indicates excessive heat, typically from a CPU overheating. A loose CPU heatsink reduces heat dissipation, causing the CPU to reach critical temperature even if the ambient temperature is normal. Redundant power supplies and stable power make a power-related thermal event unlikely. RAM incompatibility and hard drive failures do not typically trigger thermal shutdowns.
