CompTIA SK0-005 Online Questions & Answers

• Question 31:

  A server that recently received hardware upgrades has begun to experience random BSOD conditions. Which of the following are likely causes of the issue? (Choose two.)

  A. Faulty memory
  B. Data partition error
  C. Incorrectly seated memory
  D. Incompatible disk speed
  E. Uninitialized disk
  F. Overallocated memory
  A. Faulty memory
  C. Incorrectly seated memory

  ---

  Explanation

  Faulty memory and incorrectly seated memory are likely causes of the random BSOD conditions on the server. Memory is one of the most common hardware components that can cause BSOD (Blue Screen of Death) errors on Windows systems. BSOD errors occur when the system encounters a fatal error that prevents it from continuing to operate normally. Memory errors can be caused by faulty or incompatible memory modules that have physical defects or manufacturing flaws. Memory errors can also be caused by incorrectly seated memory modules that are not properly inserted or locked into the memory slots on the motherboard. This can result in loose or poor connections between the memory modules and the motherboard.

• Question 32:

  Which of the following concepts refers to prioritizing a connection that had previously worked successfully?

  A. Round robin
  B. SCP
  C. MRU
  D. Link aggregation
  C. MRU

  Explanation

• Question 33:

  Which of the following relates to how much data loss a company agrees to tolerate in the event of a disaster?

  A. RTO
  B. MTBF
  C. PRO
  D. MTTR
  A. RTO

  ---

  Explanation

  The Recovery Time Objective (RTO) is the maximum amount of time that a company agrees to tolerate in the event of a disaster before restoring its normal operations. The RTO is based on the business impact analysis (BIA) and the criticality of the processes and data involved. The RTO helps determine the backup and recovery strategies and resources needed to minimize downtime and data loss.

• Question 34:

  A datacenter technician is attempting to troubleshoot a server that keeps crashing. The server runs normally for approximately five minutes, but then it crashes. After restoring the server to operation, the same cycle repeats. The technician confirms none of the configurations have changed, and the load on the server is steady from power-on until the crash. Which of the following will MOST likely resolve the issue?

  A. Reseating any expansion cards in the server
  B. Replacing the failing hard drive
  C. Reinstalling the heat sink with new thermal paste
  D. Restoring the server from the latest full backup
  C. Reinstalling the heat sink with new thermal paste

  ---

  Explanation

  The most likely solution to resolve the issue of the server crashing after running normally for approximately five minutes is to reinstall the heat sink with new thermal paste. A heat sink is a device that dissipates heat from a component, such as a processor or a graphics card, by transferring it to a cooling medium, such as air or liquid. A heat sink is usually attached to the component using thermal paste, which is a substance that fills the gaps between the heat sink and the component and improves thermal conductivity. Thermal paste can degrade over time and lose its effectiveness, resulting in overheating and performance issues. If a server crashes after running for a short period of time, it may indicate that the processor is overheating due to insufficient cooling. To resolve this issue, the technician should remove the heat sink, clean the old thermal paste, apply new thermal paste, and reinstall the heat sink.

• Question 35:

  A server administrator is taking advantage of all the available bandwidth of the four NICs on the server. Which of the following NIC-teaming technologies should the server administrator utilize?

  A. Fail over
  B. Fault tolerance
  C. Load balancing
  D. Link aggregation
  D. Link aggregation

  ---

  Explanation

• Question 36:

  An administrator is patching a file and print server. After rebooting the server, it begins acting strangely. The administrator tries to open Print Management, but it will not open Upon inspection, the spooler service has been disabled. The

  administrator then notices the server has services that should be enabled but are disabled.

  Which of the following actions should the administrator take next to resolve the issue as quickly as possible?

  A. Roll back the installed updates
  B. Set the services to restart automatically and reboot the server
  C. Enable the spooler service.
  D. Reboot the server into safe mode
  B. Set the services to restart automatically and reboot the server

  ---

  Explanation

  When a server is acting strangely after a patch and services that should be enabled are disabled, it's often a good first step to set the services to restart automatically and then reboot the server. This can resolve many issues as it ensures that all services start correctly upon reboot

• Question 37:

  An administrator receives an alert stating a S.M.A.R.T. error has been detected. Which of the following should the administrator run FIRST to determine the issue?

  A. A hard drive test
  B. A RAM test
  C. A power supply swap
  D. A firmware update
  A. A hard drive test

  ---

  Explanation

  A S.M.A.R.T. error is an indication of a potential failure of a hard drive. S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology and it is a feature that monitors the health and performance of hard drives. A hard drive test

  can help diagnose the issue and determine if the drive needs to be replaced.

• Question 38:

  Which of the following is typical of software licensing in the cloud?

  A. Per socket
  B. Perpetual
  C. Subscription-based
  D. Site-based
  C. Subscription-based

  ---

  Explanation

  Cloud software licensing refers to the process of managing and storing software licenses in the cloud. The benefits of cloud software licensing models are vast. The main and most attractive benefit has to do with the ease of use for software vendors and the ability to provide customizable cloud software license management based on customer needs and desires1. Cloud-based licensing gives software developers and vendors the opportunity to deliver software easily and quickly and gives customers full control over their licenses, their analytics, and more1. Cloud based licensing gives software sellers the ability to add subscription models to their roster of services1. Subscription models are one of the most popular forms of licensing today1. Users sign up for a subscription (often based on various options and levels of use, features, etc.) and receive their licenses instantly1.

• Question 39:

  A systems administrator is trying to determine why users in the human resources department cannot access an application server. The administrator reviews the application logs but does not see any attempts by the users to access the application.

  Which of the following is preventing the users from accessing the application server?

  A. NAT
  B. ICMP
  C. VLAN
  D. NIDS
  C. VLAN

  ---

  Explanation

  If the application logs do not show any attempts by users to access the application server, it is likely that some network-related issue is preventing users from accessing the server. Out of the options given, the most likely culprit is VLAN (Virtual Local Area Network).

• Question 40:

  A datacenter has ten 40U racks in a hot/cold aisle configuration. The room has adequate air conditioning, but servers located near the top of the racks are shutting down due to issues with heat.

  Which of the following should be used to reduce issues with heat?

  A. Rack balancing
  B. Higher-capacity PDUs
  C. Rail kits
  D. Blanking panels
  D. Blanking panels

  ---

  Explanation

  Blanking panels are used to fill empty spaces in server racks. By blocking airflow gaps between servers, blanking panels help to direct airflow properly, ensuring that the cold air from the cold aisle is not wasted and that the hot air from the hot

  aisle is contained. This is crucial for maintaining the efficiency of cooling systems in a hot/cold aisle configuration.

  Rack balancing addresses the physical distribution of equipment, but it does not directly address thermal issues.

  Higher-capacity PDUs (Power Distribution Units) provide more power, but they do not address cooling or airflow problems.

  Rail kits are used for mounting servers and are unrelated to cooling efficiency.
