Source-backed answer review
The free daily CompTIA Server+ set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations and any extra learning features. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.
Question 1 Administrators transfer sensitive backup files between two data centers over an untrusted network. Which protection is MOST directly required to prevent passive observers from reading the transfer?
Answer choices
- A. Increase the RAID stripe size.
- B. Encrypt the data in transit using a protected transport.
- C. Rely only on disk encryption at the source server.
- D. Change the source server's asset tag.
Correct answer
Encrypt the data in transit using a protected transport.
Objective 3.1 explicitly includes encryption in transit. A protected transport addresses confidentiality while the data crosses an untrusted network.
Wrong-answer review
- A. Increase the RAID stripe size.: RAID stripe size affects storage layout, not network confidentiality.
- C. Rely only on disk encryption at the source server.: At-rest encryption protects stored data but does not by itself protect plaintext transmitted over the network.
- D. Change the source server's asset tag.: Asset labeling does not encrypt network traffic.
Extra learning features
Why this matters
Understanding encryption in transit is critical because a data center’s security posture depends on protecting sensitive backup files during transfer. Without this protection, a passive observer could intercept and read the data, leading to a significant breach of confidentiality and potential legal ramifications. This directly impacts the organization’s ability to maintain compliance with data protection regulations and avoid costly data loss.
Question 2 A security and operations team wants server event logs retained centrally even if a server is later rebuilt or loses its local logs. Which configuration BEST meets that requirement?
Answer choices
- A. Store the server's IP address in the asset database instead of collecting logs.
- B. Keep the only copy of every log on each server's local system disk.
- C. Disable log generation after the server reaches steady state.
- D. Configure event-log shipping to a centralized logging destination with appropriate retention.
Correct answer
Configure event-log shipping to a centralized logging destination with appropriate retention.
Question 3 Before attempting a live disaster-recovery failover, management wants application owners, infrastructure staff, and communications leads to walk through the runbook and discuss decisions without switching production systems. Which test type BEST fits?
Answer choices
- A. A RAID rebuild
- B. A disk wipe
- C. A live production failover
- D. A tabletop exercise
Correct answer
A tabletop exercise
Question 4 An application server starts with normal memory usage after each restart, but its process consumes steadily more RAM over several days until the system begins swapping heavily. No workload increase is observed. Which cause is MOST likely?
Answer choices
- A. A RAID mirror rebuild that never runs
- B. An application memory leak
- C. A short DHCP lease
- D. A larger rack unit size
Correct answer
An application memory leak
Question 5 A management application permits 25 users to be logged in at the same time, even though 120 named employees may use the software at different times. Which licensing model BEST matches the stated limit?
Answer choices
- A. Per-core licensing
- B. Per-socket licensing
- C. Node-locked licensing to one server console only
- D. Per-concurrent-user licensing
Correct answer
Per-concurrent-user licensing
Question 6 A rack's measured steady-state load is 2.8 kW and brief startup peaks reach 3.4 kW. A proposed UPS is rated for only 3.0 kW. Which action is BEST before putting the rack into production?
Answer choices
- A. Select a UPS with sufficient output capacity and runtime for the measured peak load plus appropriate design margin.
- B. Connect the UPS only to network switches and plug all servers directly into utility power.
- C. Use the 3.0 kW UPS because steady-state load is below its rating.
- D. Disable one redundant power supply in every server to reduce the UPS requirement.
Correct answer
Select a UPS with sufficient output capacity and runtime for the measured peak load plus appropriate design margin.
Question 7 A hardware adapter worked normally until a firmware upgrade. Immediately afterward, the server begins generating adapter reset errors, and the vendor release notes list a known incompatibility with the installed driver. What is the BEST remediation?
Answer choices
- A. Use a supported driver/firmware combination.
- B. Ignore the vendor compatibility notice.
- C. Replace every network cable.
- D. Increase the disk quota.
Correct answer
Use a supported driver/firmware combination.
Question 8 Several Linux application servers need concurrent access to the same directory tree using file-level semantics and centrally managed permissions. The applications expect to mount a remote filesystem rather than consume raw block devices. Which solution BEST fits?
Answer choices
- A. A local RAID 0 volume in each server
- B. A Fibre Channel HBA with no shared storage target
- C. An iSCSI LUN presented directly to every host without a clustered filesystem
- D. NAS providing NFS shares
Correct answer
NAS providing NFS shares
Question 9 A Linux web service works when SELinux enforcement is disabled but fails with `AVC denied` messages when enforcement is enabled. The application should remain under SELinux protection. What is the BEST troubleshooting approach?
Answer choices
- A. Change the DHCP lease duration.
- B. Leave SELinux disabled permanently without analysis.
- C. Correct SELinux policy/labels from the denial logs.
- D. Replace the RAID controller.
Correct answer
Correct SELinux policy/labels from the denial logs.
Question 10 A Linux administrator needs a native shell script for startup and service-management tasks on servers where Bash is already the standard shell. Which script type from the Server+ objective list is the MOST direct fit?
Answer choices
- A. A RAID metadata file
- B. An NFS export entry used as executable logic
- C. Bash
- D. VBS as the only possible Linux shell
Correct answer
Bash
