최신 Linux+ XK0-006 무료샘플문제 (Q28-Q33):

질문 # 28
A systems administrator is having issues with a third-party API endpoint. The administrator receives the following output:

Which of the following actions should the administrator take to resolve the issue?

정답：B

설명：
This scenario represents a name resolution failure, which is a common troubleshooting case addressed in CompTIA Linux+ V8. The critical clues are the error messages returned by both curl and dig.
The curl error "Could not resolve host" indicates that the system is unable to translate the hostname into an IP address. This is confirmed by the dig output, which returns NXDOMAIN, meaning the DNS resolver cannot resolve the requested domain name. Importantly, the dig output shows that the query is reaching a DNS server (10.255.255.254), but the resolution fails, strongly pointing to a DNS client configuration issue.
Option C, reviewing and fixing the DNS client configuration file (such as /etc/resolv.conf or systemd- resolved settings), is the correct action. Linux+ V8 documentation highlights DNS misconfiguration as a primary cause of application connectivity issues. Incorrect nameserver entries, unreachable DNS servers, or misconfigured resolvers commonly produce NXDOMAIN responses.
The other options are incorrect. Firewall issues would result in connection timeouts, not DNS resolution failures. Requesting a new API endpoint is unnecessary without first confirming local DNS functionality.
Internet connectivity issues would typically prevent any DNS communication, but here a DNS server is clearly being contacted.
Linux+ V8 stresses a layered troubleshooting approach: verify DNS resolution before investigating network ports or application logic. Therefore, the correct answer is C. Review and fix the DNS client configuration file.


질문 # 29
A systems administrator needs to set the IP address of a new DNS server. Which of the following files should the administrator modify to complete this task?

정답：C

설명：
DNS client configuration is a foundational Linux networking task covered in Linux+ V8 system management objectives. When an administrator needs to specify the IP address of a DNS server that the system should use for name resolution, the correct file to modify is /etc/resolv.conf.
The /etc/resolv.conf file defines DNS resolver settings, including one or more nameserver entries that specify the IP addresses of DNS servers. Applications and system services rely on this file to resolve hostnames to IP addresses.
The other options are incorrect. /etc/whois.conf configures WHOIS queries. /etc/nsswitch.conf controls the order of name resolution sources but does not define DNS server IP addresses. /etc/dnsmasq.conf configures a local DNS caching service, not the system-wide resolver directly.
Linux+ V8 documentation highlights /etc/resolv.conf as the authoritative DNS client configuration file, though it may be dynamically managed by tools such as NetworkManager or systemd-resolved.
Therefore, the correct answer is B. /etc/resolv.conf.


질문 # 30
While hardening a system, an administrator runs a port scan with Nmap, which returned the following output:

Which of the following is the best way to address this security issue?

정답：B

설명：
This scenario falls under the Security domain of the CompTIA Linux+ V8 objectives and focuses on system hardening and service minimization. The Nmap scan output reveals that port 23 (Telnet) is open on the system, which represents a significant security risk.
Telnet is an insecure, legacy protocol that transmits authentication credentials and session data in plaintext, making it vulnerable to interception through packet sniffing or man-in-the-middle attacks. Linux+ V8 documentation explicitly emphasizes the principle of least functionality, which states that unnecessary or insecure services should be disabled and removed entirely rather than merely restricted.
Option D, disabling and removing the Telnet service on the server, is the best and most secure solution. This action eliminates the vulnerable service completely, ensuring that it cannot be exploited internally or externally. In secure Linux environments, Telnet should be replaced with SSH, which provides encrypted communication and strong authentication mechanisms.
Option A, blocking port 23 with a firewall, reduces exposure but does not eliminate the underlying risk. If the firewall rules are misconfigured or bypassed, the Telnet service would still be available. Linux+ V8 best practices recommend removing insecure services rather than relying solely on perimeter controls.
Option B is unrelated, as changing passwords does not address the risk of plaintext credential transmission.
Option C is incorrect because closing ports at the network switch level is not an appropriate or scalable solution for host-level service hardening and does not address internal access risks.
Linux+ V8 documentation consistently highlights service auditing, port scanning, and removal of insecure protocols as essential system hardening steps. Therefore, the most effective and secure remediation is to disable and remove the Telnet service.


질문 # 31
A Linux administrator installed a new program inside $HOME/.local/bin and is trying to execute it without using an absolute path. Which of the following should the administrator use for this task?

정답：A

설명：
The correct answer is C. export PATH=$PATH:$HOME/.local/bin because it correctly appends the directory
$HOME/.local/bin to the existing PATH environment variable. The PATH variable defines a list of directories that the shell searches when a user enters a command without specifying its full path. By adding a directory to PATH, executables within that directory can be run directly from the command line.
In this case, the administrator installed a program in $HOME/.local/bin, which is not always included in the default PATH for all systems or users. By using export PATH=$PATH:$HOME/.local/bin, the existing PATH is preserved and extended to include the new directory. The use of $PATH ensures that previously defined directories remain accessible, while the colon (:) separates multiple directory entries.
Option A is incorrect because it literally assigns the string "PATH" instead of referencing the current PATH variable, effectively breaking command lookup.
Option B and D are incorrect because they attempt to assign a value to $PATH, which is invalid syntax.
Environment variables should be assigned using their name (PATH), not with a dollar sign.
From a Linux+ perspective, managing environment variables is a fundamental skill in user and system configuration. Properly configuring the PATH variable ensures efficient command execution and usability, especially when installing custom or user-specific applications. For persistence, this change is typically added to shell configuration files like ~/.bashrc or ~/.profile.


질문 # 32
Application owners are reporting that their application stops responding after several days of running, and they need to restart it. A Linux administrator obtains the following details from the dmesg command:
invoked oom-killer
Call Trace:
out_of_memory
oom_kill_process
The application owners mentioned that resources to the system have been increased, and the error takes longer to appear. Which of the following best describes the reason the process is being terminated by OOM?

정답：C

설명：
The correct answer is C. The application might have a memory leak because the dmesg output clearly shows that the Linux kernel is invoking the OOM (Out Of Memory) killer, which terminates processes when the system runs out of available memory. The presence of entries such as invoked oom-killer, out_of_memory, and oom_kill_process confirms that the system is exhausting its memory resources over time.
A key detail in the scenario is that the application runs for several days before failing, and when system resources (RAM) are increased, the issue takes longer to occur. This behavior is a classic indicator of a memory leak, where an application gradually consumes more memory without releasing it. Instead of stabilizing, memory usage continuously grows until it reaches the system limit, at which point the OOM killer terminates the process to prevent system instability.
Option A (CPU type is incompatible) is incorrect because CPU incompatibility would cause immediate execution failures, not delayed memory exhaustion. Option B (kernel panic) is incorrect because a kernel panic would crash the entire system, not selectively terminate a user-space process. Option D (swap configuration not correctly sized) is partially plausible but not the best answer; while insufficient swap can contribute to OOM conditions, it does not explain the gradual memory consumption pattern observed.
In Linux+ troubleshooting, identifying memory leaks is critical when dealing with long-running applications.
Administrators should monitor memory usage using tools like top, htop, or ps, and investigate application behavior. Applying patches, optimizing code, or restarting services periodically are common mitigation strategies, along with configuring appropriate memory and swap resources.
