Explanation of Answer E:This option correctly matches the Kubernetes components with their descriptions:

Kubectl- d. Command-line interface used to control Kubernetes

Etcd- f. Stores configuration data relating to the cluster

Kubelet- c. Agent that allows nodes to communicate with the API

Kube-proxy- e. Performs networking functions and routes network traffic

Option B (Correct):Thefdisk -lcommand lists information about all available disks, including their sizes, partition tables, and partition details.

Option E (Correct):fdiskcannot handle disks larger than 2 TB because it is limited to the Master Boot Record (MBR) partitioning scheme. To manage larger disks (over 2 TB), the GUID Partition Table (GPT) is required, andfdiskdoes not fully support GPT.

Option A (Incorrect):fdiskdoes not support HFS (Hierarchical File System, used by macOS). It primarily supports MBR and has limited support for GPT.

Option C (Incorrect):fdiskdoes not support partitioning disks larger than 2 TB with GPT;gdiskorpartedshould be used instead.

Option D (Incorrect):fdiskdoes not divide logical devices into block disks called partitions; it operates on physical storage devices to create partitions.

Explanation of Answer D:The/etc/login.defsfile in Oracle Linux contains configuration settings related to user account policies, including password aging controls. This includes settings such asPASS_MAX_DAYS,PASS_MIN_DAYS, andPASS_WARN_AGE, which define the maximum number of days a password is valid, the minimum number of days between password changes, and the number of days before password expiration to warn users, respectively.

Explanation of Answer E:The/etc/login.defsfile also contains settings for the encryption method used to encrypt user passwords. TheENCRYPT_METHODparameter specifies the hashing algorithm, such as SHA512, that is used to encrypt user passwords stored in/etc/shadow.

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.
