Why is the oracle user denied access to the FTP server on host01.example.com?
A. The oracle user is listed in /etc/vsftpd/user_list and USERLIST_ENABLE is set to YES in /etc/vsftpd
/vsftpd.conf.
B. The oracle user does not exist on host01.example.com.
C. The oracle user is listed in /etc/vsftpd/ftpusers.
D. LOCAL_ENABLE is set to NO in /etc/vsftpd/vsftpd.conf.
E. The oracle user is listed in /etc/vsftpd/user_list and USERLIST_ENABLE is set to NO in /etc/vsftpd
/vsftpd.conf.
正解：A
解説：

Which two statements are true about kernel boot parameters?
A. Each kernel version's boot parameters are stored in independent configuration files in/boot/loader
/entries.
B. Parameters passed to the kernel from the GRUB 2 menu are persistent and apply to all subsequent reboots.
C. Boot parameters are defined as values for the GRUB_CMDLINE_LINUX directive in the /etc/default
/grub file.
D. Boot parameters defined as values for the GRUB_BOOT command-line interface are persistent and apply to all subsequent reboots.
正解：A、C
解説：
* Option A (Correct):Boot parameters are set in/etc/default/grubunder
theGRUB_CMDLINE_LINUXdirective. After modifying this file, thegrub2-mkconfigcommand must be run to apply changes.
* Option C (Correct):The/boot/loader/entries/directory contains configuration files for each kernel version, which store the boot parameters separately.
* Option B (Incorrect):Boot parameters specified at the GRUB command line are not persistent across reboots unless added to the configuration file.
* Option D (Incorrect)arameters set from the GRUB menu are temporary and do not apply to subsequent reboots.

Examine this command:
$ podman run -name=oracleshell -it oraclelinux:8 -slim
Which two statements are true upon execution?
A. The container is removed by typing exit at the bash shell prompt.
B. The container named oracleshell must already exist; otherwise, the command fails.
C. The container creates and starts an interactive shell.
D. The container is created and started in a single command.
E. The command fails if the oraclelinux:8 -slim image does not exist on the local machine.
正解：C、D
解説：
Understanding the Command:
$ podman run --name=oracleshell -it oraclelinux:8-slim
(Note: The image is likely oraclelinux:8-slim without a space.)
* podman run:Creates and starts a new container.
* --name=oracleshell:Assigns the name oracleshell to the container.
* -it:Runs the container in interactive mode with a pseudo-TTY.
* oraclelinux:8-slim:Specifies the image to use.
Option A: The container creates and starts an interactive shell.
* Explanation:
* The -it option runs the container interactively.
* If no command is specified, it executes the default command in the image (usually /bin/bash).
* This provides an interactive shell inside the container.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Running Containers Interactively:
"You can run a container in interactive mode using the -i and -t options together." Option D: The container is created and started in a single command.
* Explanation:
* The podman run command handles both creation and starting of the container.
* There's no need to create the container separately.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Creating and Running Containers:
"The podman run command creates and starts a container in one operation." Why Other Options Are Incorrect:
Option B:The container does not need to pre-exist; podman run creates it if it doesn't exist.
Option C:If the image doesn't exist locally, podman will attempt to pull it from the registry.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Pulling Images:
"If you attempt to run a container with an image that does not exist locally, Podman automatically pulls the image from a registry." Option E:The container is not removed upon exit unless the --rm option is used.
* Oracle Linux Reference:
* OracleLinux 8: Managing Containers-Automatically Removing Containers:
"Use the --rm option to automatically remove the container when it exits." Conclusion:
* Correct Options:A, D
* Summary:The command creates and starts a new container named oracleshell and opens an interactive shell session inside it.
