Oracle Linux 8 Advanced System Administration Sample Questions (Q58-Q63):

NEW QUESTION # 58
Examine this command and output:
# cat deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 2
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.14.2
ports:
- containerPort: 80
Now examine this command which executes successfully:
$ kubectl create -f deployment.yaml
Which two statements are true?

A. The command creates and guarantees the availability of a specified number of identical pods.
B. The command specifies nginx image version 1.14.2 and will fail if the image version is not available.
C. The command specifies port 80 as the port that the container exposes.
D. The command creates a pod named nginx.
E. The command creates a deployment named nginx.

Answer: A,C

Explanation:
* Option A (Correct):The command creates a Kubernetes Deployment, which ensures the specified number of replicas (pods) are running at all times. The deployment will manage the creation and maintenance of these pods to ensure availability.
* Option D (Correct):The deployment configuration specifies that the container running inside the pod exposes port 80 (containerPort: 80).
* Option B (Incorrect):The deployment is namednginx-deployment, notnginx.
* Option C (Incorrect):The command creates a Deployment object that manages multiple pods; it does not directly create a single pod namednginx.
* Option E (Incorrect):The command specifies the nginx image version1.14.2, but it will not fail immediately if the image version is not available. Kubernetes will attempt to pull the image, and the failure will happen during that step if the image does not exist.
Oracle Linux Reference:Refer to:
* Kubernetes Documentation on Deployments
* kubectl createcommand usage details.

NEW QUESTION # 59

NEW QUESTION # 60
Which three statements are true about DNF modules?

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

Answer: B,E,G

Explanation:
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.

NEW QUESTION # 61
Which command configures a fully functional and accessible interface on VLAN 800?

A. modprobe 8021q ip link add link eth0 name eth0.800 VLAN 800 ip address add 10.135.1.120/24 dev eth0.800 ip link set eth0.800 up
B. modprobe 8021q ip link add link eth0 name eth0.800 type vlan id 800 ip link set eth0.800 up
C. modprobe 8021q ip address add 10.135.1.120/24 dev eth0.800 ip link set eth0.800 up
D. modprobe 8021q ip link add link eth0 name eth0.800 type vlan id 800 ip address add 10.135.1.120/24 dev eth0.800 ip link set eth0.800 up

Answer: D

Explanation:
* Option C (Correct):This command sequence first loads the 802.1q module needed for VLAN tagging, then creates a VLAN interface (eth0.800) on the base interface (eth0), assigns an IP address (10.135.1.120/24), and sets the VLAN interface up.
* Option A, B, D (Incorrect):These options have syntactical errors or missing parameters that make them incorrect for setting up a fully functional and accessible VLAN interface.
Oracle Linux Reference:Refer to:
* OracleLinux 8: Configuring VLANs

NEW QUESTION # 62
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.

Answer: A,E

Explanation:
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.
