CompTIA SK0-005 Online Questions & Answers

• Question 201:

  Which of the following commands would MOST likely be used to register a new service on a Windows OS?

  A. set-service
  B. net
  C. sc
  D. services.msc
  C. sc

  ---

  Explanation

  The command that would most likely be used to register a new service on a Windows OS is "sc".

  "sc" is a command-line utility that is used to manage Windows services. It can be used to create, modify, start, stop, and delete services, among other things. The "create" command in particular is used to create a new service.

  The other options listed (A, B, and D) are not used specifically for registering new services. "set-service" is used to modify the settings of an existing service, "net" is used for managing network resources, and "services.msc" is a graphical

  user interface (GUI) tool for managing services.

• Question 202:

  A server administrator wants to run a performance monitor for optimal system utilization. Which of the following metrics can the administrator use for monitoring? (Choose two.)

  A. Memory
  B. Page file
  C. Services
  D. Application
  E. CPU
  F. Heartbeat
  A. Memory
  E. CPU

  ---

  Explanation

  Memory and CPU are two metrics that can be used for monitoring system utilization. Memory refers to the amount of RAM that is available and used by the system and its processes. CPU refers to the percentage of processor time that is consumed by the system and its processes. Both memory and CPU can affect the performance and responsiveness of the system and its applications. Monitoring memory and CPU can help identify bottlenecks, resource contention, memory leaks, high load, etc.

• Question 203:

  A server administrator set up a monitoring application on various servers to keep track of CPU usage, memory consumption, and disk space utilization.

  Which of the following should be configured on the application so it can send email alerts about a specific issue?

  A. Event logs
  B. Thresholds
  C. Disk quotas
  D. Uptime lengths
  B. Thresholds

  ---

  Explanation

  Configuring thresholds allows the monitoring application to define limits (e.g., CPU usage andgt;90%, disk space andlt; 10%) that trigger email alerts when exceeded. This proactive measure helps administrators address issues before they

  escalate.

  Event logs: Provide historical data but do not send alerts.

  Disk quotas: Restrict user disk usage but are unrelated to alerts.

  Uptime lengths: Measure server runtime but do not trigger alerts.

• Question 204:

  While a technician is troubleshooting a performance issue on a database server, users are disconnected from the database. An administrator is asked to intervene and restore access.

  Which of the following steps should the administrator take first?

  A. Revert any patches or updates on the server from the past 24 hours
  B. Reproduce the issue in a test environment and confirm the database fails in the same manner.
  C. Perform a root cause analysis and report the issue to management.
  D. Collect all logs from the system and review the actions the technician performed.
  E. Perform a quick backup of the system to prevent any further issues.
  D. Collect all logs from the system and review the actions the technician performed.

  ---

  Explanation

  The first step when addressing an urgent issue like a database disconnection should be to gather information to understand what actions caused the problem.Collecting all logs and reviewing the technician's actions (Answer D)will help

  identify what went wrong and guide appropriate remediation. Restoring access quickly is the priority, and without reviewing logs, it would be hard to identify the root cause or prevent further damage. Reverting patches (Option A):Reverting

  patches might cause more issues if the problem isn't directly related to a recent update. Reproducing the issue (Option B):Reproduction is useful in a controlled environment but not practical as an immediate first step in production.

  Root cause analysis (Option C):This is necessary but should come after restoring access.

  Performing a quick backup (Option E):While backups are crucial, this step might not help resolve the current access problem and can delay troubleshooting.

  This topic relates toSK0-005 Objective 3.4: Explain troubleshooting theory and methodologies.

• Question 205:

  A systems administrator is investigating a server with a RAID array that will not boot into the OS. The administrator notices all the hard drives are reporting to be offline. The administrator checks the RAID controller and verifies the configuration is correct. The administrator then replaces one of the drives with a known-good drive, but it appears to be unavailable as well. Next, the administrator takes a drive out of the server and places it in a spare server, and the drive is available and functional. Which of the following is MOST likely causing the issue?

  A. The kernel is corrupt.
  B. Resources are misallocated.
  C. The backplane has failed.
  D. The drives need to be reseated.
  C. The backplane has failed.

  ---

  Explanation

  There may be many causes of storage problems on a server or its related components. Boot errors might cause by:

  1.Misconfigured RAID array

  2.Drive failure

  3.Controller or HBA failure

  4.Loose connections or cable failures

  5.Corrupt boot sector

  6.Corrupt file system table

  7.Backplane failure

  The server's backplane provides a communications bus among devices that you may install. The backplane is an additional circuit board attached to the motherboard, and not all servers have one. Damage to the backplane--either physical or electrical--may keep devices on this bus from communicating correctly.

• Question 206:

  An administrator restores several database files without error while participating in a mock disaster recovery exercise. Later, the administrator reports that the restored databases are corrupt and cannot be used. Which of the following would best describe what caused this issue?

  A. The databases were not backed up to be application consistent.
  B. The databases were asynchronously replicated
  C. The databases were mirrored
  D. The database files were locked during the restoration process.
  A. The databases were not backed up to be application consistent.

  ---

  Explanation

  Application consistent backup is a method of backing up data that ensures the integrity and consistency of the application state. It involves notifying the application to flush its data from memory to disk and quiescing any write

  operations before taking a snapshot of the data. If the databases were not backed up to be application consistent, they might contain incomplete or corrupted data that cannot be restored properly.

• Question 207:

  A technician ordered two additional hard drives to expand an existing RAID 6 configuration. The technician added the new disks and then rebooted. After rebooting, the technician did not see the additional space in the existing disk, and the OS detected two new disks that needed signatures. Which of the following should the technician complete next to expand the existing RAID configuration?

  A. Modify the existing disk to a dynamic disk and add the two new raw disks to the existing array.
  B. Allow the OS to write GPT signatures to the disks and add them as dynamic disks to the existing disk.
  C. Reboot the server, start the RAID utility from the BIOS, and expand the RAID 6 with the two new disks.
  D. Use the software RAID in the OS to create a RAID 0 with the existing array and the two new disks.
  C. Reboot the server, start the RAID utility from the BIOS, and expand the RAID 6 with the two new disks.

• Question 208:

  An administrator is installing a new server and OS. After installing the OS, the administrator logs in and wants to quickly check the network configuration. Which of the following is the best command to use to accomplish this task?

  A. tracert
  B. telnet
  C. ipconfig
  D. ping
  C. ipconfig

  Explanation

• Question 209:

  Due to a recent application migration, a company's current storage solution does not meet the necessary requirements tor hosting data without impacting performance when the data is accessed in real time by multiple users. Which of the following is the BEST solution for this Issue?

  A. Install local external hard drives for affected users.
  B. Add extra memory to the server where data is stored.
  C. Compress the data to increase available space.
  D. Deploy a new Fibre Channel SAN solution.
  D. Deploy a new Fibre Channel SAN solution.

  ---

  Explanation

  A Fibre Channel SAN solution is a type of storage area network (SAN) that uses high-speed optical fiber cables to connect servers and storage devices. A SAN allows for hosting data without impacting performance when the data is accessed

  in real time by multiple users, as it provides fast data transfer rates, low latency, high availability, and scalability12. A local external hard drive (A) would not be suitable for multiple users, as it would limit the accessibility and security of the

  data. Adding extra memory to the server (B) would not solve the problem of data access performance, as it would not increase the bandwidth or reduce the congestion of the network. Compressing the data ?would not improve the

  performance either, as it would add extra overhead and complexity to the data processing and retrieval.
