- B. The container is created and started in a single command.
- C. The command fails if the oraclelinux:8 -slim image does not exist on the local machine.
- D. The container creates and starts an interactive shell.
- E. The container is removed by typing exit at the bash shell prompt.
正解：B、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.

* 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.

質問 # 20
Which two are true about using Ksplice?
- A. Ksplice can be used without a network connection
- B. It can patch the kernel without shutting down the system.
- C. The Ksplice client is freely available to all customers.
- D. Ksplice has two clients; each can run in three different modes.
- E. Yum cannot upgrade a kernel patched by Ksplice
正解：A、B
解説：
Option A: Ksplice can be used without a network connection
* Explanation:
* Ksplice provides anOffline Clientspecifically designed for systems that do not have a direct connection to the internet. This client allows administrators to download Ksplice updates on a system with internet access and then transfer them to the offline system for installation.
* This means Ksplice can be effectively used in environments with strict security policies where network connectivity is restricted or not available.
* Oracle Linux Reference:
* OracleLinux 8: Ksplice User's Guide- Section on "Using the Ksplice Offline Client":
"The Ksplice Offline client enables you to apply Ksplice updates to systems that do not have direct access to the Internet or to the Oracle Uptrack server." Option B: It can patch the kernel without shutting down the system.
* Explanation:
* The primary purpose of Ksplice is to allow administrators to apply critical security patches to the running kernelwithout requiring a rebootor shutting down the system. This ensures high availability and minimizes downtime, which is crucial for production environments.
* Ksplice works by performingjust-in-time (JIT) compilationof kernel patches and applying them directly to the running kernel in memory.
* Oracle Linux Reference:
* OracleLinux 8: Ksplice User's Guide- Introduction:
"Ksplice enables you to keep your systems up to date and secure by applying important kernel security updates without rebooting." Why Other Options Are Not Correct:
* Option C:Yum cannot upgrade a kernel patched by Ksplice
* Explanation:
* This statement is false. While Ksplice patches the running kernel in memory, yum can still upgrade the kernel packages on disk. After a yum kernel update, a reboot would be necessary to run the new kernel version, but yum operations are not hindered by Ksplice patches.
* Oracle Linux Reference:
* OracleLinux 8: Ksplice User's Guide- Compatibility with Package Managers:
"Ksplice works seamlessly with package management tools like yum and dnf. You can continue to use these tools to manage your kernel packages."
* Option D:Ksplice has two clients; each can run in three different modes.
* Explanation:
* While Ksplice does have two clients (the online and offline clients), the statement about each running in three different modes is inaccurate or misleading. The clients do not operate in "three different modes" per se.
* Oracle Linux Reference:
* No official documentation supports the claim of "three different modes" for each client.
* Option E:The Ksplice client is freely available to all customers.
* Explanation:
* Ksplice is a feature available to customers with an active Oracle Linux Premier Support subscription. It is not freely available to all users.
* Oracle Linux Reference:
* OracleLinux 8: Ksplice User's Guide- Access Requirements:
"To use Ksplice, your system must be covered by an Oracle Linux Premier Support subscription." Conclusion:
Options A and B are correct because Ksplice can be used without a network connection via the offline client, and it allows patching the kernel without shutting down the system, ensuring minimal downtime.

質問 # 22
Which two statements are true about the proc and sys file systems?
- A. sys contains a list of mounted devices.
- B. sys contains information about memory and CPUs.
- C. proc contains information about memory and CPUs.
- D. sys contains a list of running processes.
- E. proc contains a list of network drivers.
正解：B、C
解説：
* Option A (Correct):The/procfile system is a pseudo-file system that contains runtime system information (e.g., system memory, mounted devices, hardware configuration, etc.). Files such as/proc
/meminfoand/proc/cpuinfoprovide detailed information about memory and CPUs, respectively.
* Option C (Correct):The/sysfile system, also known as sysfs, provides a view of the kernel's device model. It contains information about system hardware, including CPUs and memory. For example,/sys
/devices/system/cpu/contains directories and files that provide detailed information about each CPU.
* Option B (Incorrect):The/sysfile system does not contain a list of running processes. Running processes are listed in the/procfile system, with each process having its own directory under/proc.
* Option D (Incorrect):/procdoes not contain a list of network drivers specifically. Network driver information is available under/proc/net, but this does not equate to a list of drivers.
* Option E (Incorrect):The/sysfile system does not contain a list of mounted devices. Mounted devices are listed in/proc/mountsor the/etc/mtabfile.
Oracle Linux Reference:For more details, see:
* OracleLinux 8: The/procand/sysFile Systems.
質問 # 23
Which two statements are true about container technology?
- A. Podman, Buildah, and Skopeo are independent tools to create, run, and manage container applications across compatible Oracle Linux systems.
- B. Podman requires a running daemon to function and to enable containers to start and run without root permissions.
- C. A container application is dependent on the host operating system and kernel version.
- D. A container application built on a bare metal system cannot run on virtual machines or cloud instances.
- E. Containers package an application with the individual runtime stack.
正解：A、C
解説：
* Option B (Correct):Container applications are dependent on the host operating system's kernel because containers share the OS kernel, unlike virtual machines, which use a hypervisor. Compatibility of the host OS kernel version is required to run containers.
* Option D (Correct):Podman, Buildah, and Skopeo are container tools for managing container applications. Podman runs containers without requiring a daemon like Docker, Buildah is used to build container images, and Skopeo is used for transferring container images. These tools can operate independently of one another, providing a flexible and modular approach to container management on Oracle Linux.
* Option A (Incorrect):Container applications built on bare metal can run on virtual machines or cloud instances as long as the environment supports the container runtime.
* Option C (Incorrect):Containers do not package the entire runtime stack; they include the application and its dependencies but rely on the host OS for the kernel.
* Option E (Incorrect):Podman does not require a running daemon; one of its advantages over Docker is that it can run containers in rootless mode without needing a persistent daemon.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Podman and Containers Guide
* man podman,man buildah,man skopeofor further details on these tools.

Which two statements are true about systemd system and service manager?
- A. systemd is backward-compatible with the System V init scripts that were used in earlier versions of Oracle Linux.
- B. systemd reads /etc/system to determine which services to start.
- C. systemd is the first process that starts after the system boots and is the final process left running before the system shuts down.
- D. The service command is used to start and stop system service units.
- E. systemd service units expose kernel devices and can be used to implement device-based activation.
正解：A、C
解説：
Explanation of Answer B:systemdis the first process to start (PID 1) after the Linux kernel has booted and is responsible for initializing the user space and managing system services throughout the system's runtime. It is also the last process to stop during shutdown.
Explanation of Answer C:systemdmaintains backward compatibility with older System V init scripts. It can run and manage these scripts, ensuring legacy services are supported while providing newer functionalities through nativesystemdunit files.
