59. Frage
Which three statements are true about DNF modules?

A. Packages exist in multiple streams, where each stream contains a different version.
B. Streams cannot declare dependencies on the streams of other modules.
C. Modules are a group of packages that are installed together along with dependencies.
D. Streams are used to define optional configurations of modules.
E. Installing a module allows a user to select a specific stream.
F. Profiles are used to provide alternate versions of the same module.
G. Switching an enabled module stream automatically changes installed packages.

Antwort: A,C,E

Begründung:
Understanding DNF Modules:
DNF modules in Oracle Linux 8 provide a way to offer different versions of software (packages) to users, allowing them to choose the version that best suits their needs. Modules help in managing multiple versions of software by grouping packages, defining streams, and using profiles for configurations.
Option A: Modules are a group of packages that are installed together along with dependencies.
* Explanation:
* Modulesare collections of packages that are grouped together to represent an application, language runtime, or any logical set.
* When you install a module, you are installing a set of packages along with their dependencies.
* This grouping ensures that all necessary components are installed for the software to function correctly.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-About Modules:
"A module is a group of packages that represents a component, such as an application, a language runtime, or a set of tools." Option B: Installing a module allows a user to select a specific stream.
* Explanation:
* Streamsin a module represent different versions of the software.
* When installing a module, you can select a specific stream to install the desired version.
* This allows users to choose between multiple versions of the same software provided within the module.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-About Module Streams:
"Each module can have one or more streams, which represent versions of the module content."
* Example Command:
# dnf module list nodejs
* This command lists available streams for the nodejs module.
Option F: Packages exist in multiple streams, where each stream contains a different version.
* Explanation:
* Within a module, each stream can contain different versions of the packages.
* This means the same package can exist in multiple streams but with different versions in each stream.
* This setup allows users to install the version of the software that meets their requirements.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-About Module Streams:
"Different streams can contain different versions of the software, allowing you to select the version that best suits your needs." Why Other Options Are Incorrect:
Option C: Profiles are used to provide alternate versions of the same module.
* Explanation:
* Profilesdefine sets of packages within a module stream for specific use cases or configurations, not alternate versions.
* Streams provide alternate versions, whereas profiles provide different package sets within a stream.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-About Module Profiles:
"A profile is a list of packages that defines a particular use case for a module stream." Option D: Streams are used to define optional configurations of modules.
* Explanation:
* Streams define different versions of software, not optional configurations.
* Optional configurations are managed through profiles within a stream.
* Oracle Linux Reference:
* Profiles handle configurations, while streams handle versions.
Option E: Streams cannot declare dependencies on the streams of other modules.
* Explanation:
* Streams can declare dependencies on specific streams of other modules.
* This allows modules to work together with compatible versions.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-Module Dependencies:
"Modules can declare dependencies on specific streams of other modules." Option G: Switching an enabled module stream automatically changes installed packages.
* Explanation:
* Switching streams does not automatically change installed packages.
* You must reset the module and install the new stream's packages manually.
* Oracle Linux Reference:
* OracleLinux 8: Managing Software-Switching Module Streams:
"To switch to a different module stream, you must reset the module and then install the packages from the new stream." Conclusion:
* Correct Options:A, B, F
* Summary:Modules group packages with dependencies, installing a module allows selecting a specific stream (version), and packages can exist in multiple streams with different versions.

60. Frage
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. Ksplice has two clients; each can run in three different modes.
D. The Ksplice client is freely available to all customers.
E. Yum cannot upgrade a kernel patched by Ksplice

Antwort: A,B

Begründung:
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.

61. Frage
Examine these commands, which execute successfully:
# firewall-cmd --zone=public --add-service=cockpit --permanent
# firewall-cmd --zone=public --add-port=1313/tcp --permanent
# firewall-cmd --reload
Which are true upon execution?

A. Runtime firewall configuration is not lost when the firewalld process is restarted or the system is rebooted.
B. Port 1313 blocks all traffic for the public zone except for ingress traffic to the Cockpit service.
C. Egress traffic is allowed for the Cockpit service only when using port 1313.
D. The custom Cockpit service configuration file is updated in /usr/lib/firewalld/services.
E. The Cockpit service is added only to the public zone.

Antwort: A,E

Begründung:
Explanation of Answer A:The commandfirewall-cmd --zone=public --add-service=cockpit --permanentadds the Cockpit service to the public zone permanently. This means that the service is explicitly allowed only within the public zone, not in any other zones.
Explanation of Answer C:Using the--permanentflag withfirewall-cmdcommands ensures that the changes are stored in the firewalld configuration and are persistent across reboots. Therefore, when thefirewalldservice restarts or the system reboots, the runtime configuration will not be lost, and the changes will remain in effect.

62. Frage
Examine this udev device naming rule which gets processed successfully:
makefile
KERNEL=="hdb", DRIVER=="ide-disk", SYMLINK+="sparedisk"
Which two statements are true?

A. The matching device will have the kernel device name /dev/hdb.
B. The matching device will be named /dev/sparedisk.
C. Symbolic link /dev/sparedisk is created linking to /dev/hdb and with an ide-disk device driver, thus overwriting existing symbolic links.
D. Symbolic link /dev/sparedisk is created for a device named /dev/hdb or one that has an ide-disk device driver, whichever is discovered first.
E. Symbolic link /dev/sparedisk is created for a device named /dev/hdb which has an ide-disk device driver if such a device is discovered.

Antwort: A,E

Begründung:
Option C (Correct):If a device named/dev/hdbwith theide-diskdriver is discovered, a symbolic link/dev
/sparediskwill be created, pointing to/dev/hdb.
Option D (Correct):TheKERNEL=="hdb"match specifies that the device will have the kernel device name
/dev/hdb.
Option A (Incorrect):This is incorrect because existing symbolic links are not overwritten unless explicitly defined.
Option B (Incorrect):The device itself is not renamed to/dev/sparedisk; rather, a symbolic link is created.
Option E (Incorrect):The rule specifically requires bothKERNEL=="hdb"andDRIVER=="ide-disk"to match; it is not an either/or condition.

63. Frage
Examine this network configuration:
NAME="ens4"
DEVICE="ens4"
ONBOOT=no
NETBOOT=yes
IPV6INIT=yes
BOOTPROTO=none
IPADDR=192.168.2.5
PREFIX=24
GATEWAY=192.168.2.1
TYPE=Ethernet
Which two statements are true after executing nmcli con mod ens4 ipv4.method auto?

A. ONBOOT value is set to yes.
B. Interface ens4 is assigned an IP address of 192.168.2.5.
C. BOOTPROTO value is set to dhcp.
D. IPADDR value is considered null.
E. ONBOOT value is set to dhcp.
F. Interface ens4 automatically starts on boot.

Antwort: C,D

Begründung:
Explanation of Answer B:When executingnmcli con mod ens4 ipv4.method auto, theipv4.methodparameter is set toauto, which configures the interface to obtain its IP address using DHCP. This means that theBOOTPROTOvalue in the configuration is set todhcp.
Explanation of Answer D:Whenipv4.methodis set toauto(DHCP), any static IP address specified inIPADDRis considered null because the interface will now obtain its IP address from a DHCP server, making the manually set IP address irrelevant.
