Question #1
What are the differences between hard disk drives and solid state disks? (Choose two.)
  1. A
    Hard disks have a motor and moving parts, solid state disks do not.
  2. B
    Hard disks can fail due to physical damage, while solid state disks cannot fail.
  3. C
    Solid state disks can store many times as much data as hard disk drives.
  4. D
    /dev/sda is a hard disk device while /dev/ssda is a solid state disk.
  5. E
    Solid state disks provide faster access to stored data than hard disks.

Correct Answer:
AE

Correct choices highlight fundamental differences in HDDs and SSDs. HDDs rely on mechanical components with a motor, susceptible to wear over time, making SSDs, which lack these moving parts, generally more durable and reliable. Additionally, SSDs provide quicker data access primarily due to their reliance on flash memory, enhancing system responsiveness. This contrasts with HDDs, where data retrieval is slowed by the mechanical movement necessary to read and write data, a notable distinction for anyone transitioning from HDDs to SSDs in performance-critical environments.

Question #2
Reverse DNS assigns hostnames to IP addresses. How is the name of the IP address 198.51.100.165 stored on a DNS server?
  1. A
    In the A record for 165.100.51.198.ipv4.arpa.
  2. B
    In the PTR record for 165.100.51.198.in-addr.arpa.
  3. C
    In the RNAME record for 198-51-100-165.rev.arpa.
  4. D
    In the ARPA record for 165.100.51.198.rev.
  5. E
    In the REV record for arpa.in-addr.198.51.100.165.

Correct Answer:
B
chatbot-img GPT-4o - Answer
In reverse DNS, the association between an IP address and its domain name is stored in a PTR record, with the domain named in the format of a reversed IP address followed by ".in-addr.arpa". For example, the PTR record for the IP address 198.51.100.165, when looked up in a DNS server, would be formatted as 165.100.51.198.in-addr.arpa, which proves correct in response B. This structure facilitates reverse DNS lookups by aligning the address mappings inversely in relation to the standard forward DNS which uses A records.

Question #3
Which of the following types of bus can connect hard disk drives with the motherboard?
  1. A
    The RAM bus
  2. B
    The NUMA bus
  3. C
    The CPU bus
  4. D
    The SATA bus
  5. E
    The Auto bus

Correct Answer:
D
chatbot-img GPT-4o - Answer
SATA, short for Serial Advanced Technology Attachment, is the standard interface for connecting hard drives, SSDs, and optical drives to the motherboard. It transmits data via a high-speed serial cable, making it efficient for storage communications. In contrast, other buses like RAM, NUMA, CPU, or Auto do not serve this specific purpose within a computer’s architecture. Always ensure your storage devices are compatible with SATA for optimal performance.

Question #4
Members of a team already have experience using Red Hat Enterprise Linux. For a small hobby project, the team wants to set up a Linux server without paying for a subscription. Which of the following Linux distributions allows the team members to apply as much of their Red Hat Enterprise Linux knowledge as possible?
  1. A
    Ubuntu Linux LTS
  2. B
    Raspbian
  3. C
    Debian GNU/Linux
  4. D
    CentOS
  5. E
    openSUSE

Correct Answer:
D
chatbot-img GPT-4o - Answer
CentOS is a superb choice for the team familiar with Red Hat Enterprise Linux as it’s built from RHEL’s source code, thus maintaining compatibility and allowing a seamless transition without the need for subscription expenses. This compatibility means the team can leverage their existing skills and tools with minimal adjustment.

Question #5
What information can be displayed by top?
  1. A
    Existing files, ordered by their size.
  2. B
    Running processes, ordered by CPU or RAM consumption.
  3. C
    User accounts, ordered by the number of logins.
  4. D
    User groups, ordered by the number of members.
  5. E
    User accounts, ordered by the number of files.

Correct Answer:
B
chatbot-img GPT-4o - Answer
The 'top' command is super useful for real-time monitoring of your system. It primarily displays the running processes along with details like CPU and RAM usage, making it great for spotting what's hogging your system's resources. Always handy for both newbies and pros trying to keep their systems in check!
