NEW QUESTION # 196
An
administrator is investigating the reason a Linux workstation is not resolving the website http://www.comptia.
org. The administrator executes some commands and receives the following output:
Which of the following is the most likely cause?
Answer: A
Explanation:
When troubleshooting name resolution issues in Linux, /etc/hosts entries take precedence over DNS lookups.
The workstation's /etc/hosts file contains the line:
CopyEdit
104.18.99.101 www.comptia.org
This means any attempt to access www.comptia.org will resolve to 104.18.99.101, regardless of the real DNS response. However, both dig and nslookup show the correct IP as 104.18.16.29. Because the local /etc/hosts entry overrides DNS, and the hardcoded IP is either incorrect or unreachable, all network traffic to www.
comptia.org will fail or not reach the intended destination, resulting in the observed connectivity issue (Destination Host Unreachable).
Other options:
* B. The lack of IPv6 support is irrelevant since the host is using IPv4 and the DNS queries for IPv4 (A record) are successful.
* C. The firewall would block all HTTP/HTTPS connections, but the error shown is a host unreachable, not a port-specific issue.
* D. The nameserver is working; both dig and nslookup queries succeed and return the correct A record.

NEW QUESTION # 197
A Linux administrator wants to make the ENABLE_AUTHvariable set to 1 and available to the environment of subsequently executed commands. Which of the following should the administrator use for this task?
Answer: B
Explanation:
The export command sets an environment variable and makes it available to subsequently executed commands and child processes, ensuring ENABLE_AUTH=1 is recognized system- wide in that shell session.
NEW QUESTION # 198
A systems administrator reviews the package management history and sees the following entries:
46 install httpd Install 9
47 update -y Upgrade 44
Which of the following commands should the administrator use to undo the installation of the httpd package from transaction 46?
Answer: D
Explanation:
The correct answer is B. yum history undo 46 because it directly reverses the specific transaction identified in the YUM history log. In Red Hat-based Linux distributions, the yum history feature allows administrators to view, manage, and undo past package operations. Each transaction is assigned a unique ID, which can be used to reverse changes accurately.
In this scenario, transaction 46 corresponds to the installation of the httpd package. Using the command yum history undo 46 will attempt to revert that exact transaction by removing the installed package and restoring the system to its previous state before that transaction occurred. This method is precise and preferred in environments where maintaining package consistency is critical.
Option A (yum remove httpd) is incorrect because although it removes the httpd package, it does not specifically reference the transaction history. It may not fully revert all dependencies or changes associated with the original installation transaction.
Option C (yum rollback 46) is incorrect because rollback is not a valid YUM command. The correct functionality is handled through the history undo or history rollback syntax, but rollback requires a different format (typically rolling back to a transaction ID, not specifying a single one in this way).
Option D (yum erase 46) is incorrect because erase expects a package name, not a transaction ID. Using a number like 46 would result in an error.
From a Linux+ system management perspective, understanding yum history commands is essential for package management, auditing, and troubleshooting. It allows administrators to safely reverse changes, ensuring system stability and proper configuration management.
NEW QUESTION # 199
On a Kubernetes cluster, which of the following resources should be created in order to expose a port so it is publicly accessible on the internet?
Answer: B
Explanation:
Container orchestration concepts are part of the Automation and Orchestration domain in Linux+ V8. In Kubernetes, workloads run inside Pods, but Pods are not directly accessible from outside the cluster.
To expose an application externally, a Service resource must be created. Services provide a stable network endpoint and can be configured as NodePort, LoadBalancer, or ClusterIP. Public exposure is typically achieved using NodePort or LoadBalancer types.
Option C, Service, is correct. Deployments manage Pods, but they do not handle networking exposure. Pods represent running containers but lack external accessibility by default. "Network" is not a valid Kubernetes resource type.
Linux+ V8 documentation highlights Services as the mechanism for exposing containerized applications. Therefore, the correct answer is C.
NEW QUESTION # 200
A systems administrator needs to restore a backup to the /usr/app/data directory. Which of the following commands should the administrator use for this task?
Answer: D
Explanation:
The tar (tape archive) utility is the standard tool for archiving and compressing files in Linux.
According to CompTIA Linux+ V8 objectives, administrators must be proficient in extracting data into specific target locations. The command tar -xvzf /tmp/backup.tar.gz -C /usr/app/data is the correct syntax for this operation.
The flags used in the command provide the following functionality:
-x: Instructs tar to extract the contents of the archive.
-v: Enables verbose output, showing the files as they are being extracted.
-z: Tells tar to filter the archive through gzip for decompression (required for .tar.gz files).
-f: Specifies the filename of the archive to be processed (/tmp/backup.tar.gz).
-C: Changes the directory to the specified path (/usr/app/data) before performing the extraction.
Using the -C flag is the most efficient and recommended way to restore a backup to a directory other than the current working directory. Without this flag, tar would extract the files into the current directory, which might not be the intended destination and could clutter the filesystem.
