トピック出題範囲
トピック 1
  • The Linux Operating System: Targeted at the IT Support Technician, this domain covers the selection of operating systems and their life cycles, differences between major OS types, and essential hardware components including storage and drivers. It further explores how data is stored and logged in a Linux system, and mandates competence in querying network configurations, understanding TCP
  • IP concepts, and verifying connectivity using basic networking tools.
トピック 2
  • Finding Your Way on a Linux System: Aimed at the Junior Linux System Administrator, this domain evaluates competence using the Linux command line. Candidates must demonstrate an understanding of shell syntax, environment variables, and quoting conventions. They are expected to navigate help systems such as man and info pages, manipulate directories and files through absolute and relative paths, and perform basic file operations including creation, movement, and deletion.

  • The Linux Community and a Career in Open Source: This section of the exam measures skills of an Aspiring Open Source Developer and covers the history and growth of Linux along with its major distributions, embedded uses like Raspberry Pi, and its role in cloud computing. It also requires familiarity with prominent open source applications across desktop, server, and development contexts, including package management tools. Additionally, it addresses open source philosophy and licensing principles, and evaluates basic ICT skills relevant to working within Linux environments.
トピック 4
  • The Power of the Command Line: This section measures the abilities of a Linux Script Developer and focuses on archive management using tools like tar and gzip, as well as data searching and filtering via utilities such as grep and cut. It also assesses the capacity to transform repetitive commands into simple shell scripts, employing constructs such as shebang lines, loops, variables, and error handling to automate tasks.
トピック 5
  • Security and File Permissions: This section evaluates the expertise of a Linux Security Administrator in user and group management, permission structures, and directory security. It addresses root and system user distinctions, account creation and modification processes, and manipulation of file ownership and permission settings.

Lpi Linux Essentials Certificate Exam - version 1.6 認定 010-160 試験問題 (Q15-Q20):

質問 # 15
Reverse DNS assigns hostnames to IP addresses. How is the name of the IP address 198.51.100.165 stored on a DNS server?

正解:C

解説:
Reverse DNS lookups query DNS servers for a PTR (pointer) record; if the server does not have a PTR record, it cannot resolve a reverse lookup. PTR records store IP addresses with their segments reversed, and they append ".in-addr.arpa" to that. For example, if a domain has an IP address of 192.0.2.1, the PTR record will store the domain's information under 1.2.0.192.in-addr.arpa. In IPv6, the latest version of the Internet Protocol, PTR records are stored within the ".ip6.arpa" domain instead of ".in-addr.arpa."1 Therefore, the name of the IP address 198.51.100.165 is stored in the PTR record for 165.100.51.198.in-addr.arpa.

質問 # 16
Which license best describes the GPL's core philosophy?

正解:B


質問 # 17
What does the `~` symbol represent in a Linux shell?

正解:B


質問 # 18
When typing a long command line at the shell, whatsingle charactercan be used to split a command across multiple lines?

正解:

解説:
Explanation
The backslash character () is used to escape the meaning of the next character in a command line. This means that the next character is treated as a literal character, not as a special character. For example, if you want to use a space in a file name, you can use a backslash before the space to prevent the shell from interpreting it as a separator. Similarly, if you want to split a long command line across multiple lines, you can use a backslash at the end of each line to tell the shell that the command is not finished yet. The shell will ignore the newline character and continue reading the next line as part of the same command.
For example, you can write:
ls -l/home/user/Documents
instead of:
ls -l /home/user/Documents
Both commands will produce the same output, but the first one is easier to read and type. References:

質問 # 19
Which of the following commands sets the variable USERNAME to the value bob?

正解:C

解説:
The correct command to set the variable USERNAME to the value bob is USERNAME=bob. This command assigns the string bob to the variable name USERNAME, using the equal sign (=) as the assignment operator. There is no space around the equal sign, and the variable name and value are case-sensitive. This command sets a shell variable, which is only valid in the current shell session. To make the variable an environment variable, which can be inherited by child processes and subshells, you need to use the export command, such as export USERNAME=bob. The other commands are not valid for setting variables in Linux. The set command is used to set or unset shell options and positional parameters, not variables. The $ sign is used to reference the value of a variable, not to assign it. The == sign is used for comparison, not assignment. The var keyword is not used in Linux, but in some other programming languages. The <= sign is used for redirection, not assignment. Reference:
