SSSD provides access to different identity and authentication providers. The configuration file typically contains multiple sections, but the [sssd] section is always present. This section provides global options that apply to all other sections of the file.Example:[sssd] config_file_version = 2 services = nss, pam domains = LDAPReference:SSSD ConfigurationSSSD Man PagesNO.28 Which parameter in a user object defines on which share the user’s roaming profile is stored?  autoMount  logonDrive  profilePath  homePath  driveMap The profilePath parameter in a user object specifies the path to the user’s roaming profile. A roaming profile is a feature in Windows that allows user profile data to be stored on a network share so that users can access their profiles from any workstation within the network. By setting the profilePath, administrators can define where on the network the profile data is stored.Reference:Roaming User ProfilesUser Account PropertiesNO.29 The configuration of a Samba share contains the following line:force directory mode = 0555If a client creates a new directory with the permissions 0750, which permissions will the resulting directory have in the Samba server’s file system?  0755  0750  0750  0555  0777 force directory mode = 0555: This setting in Samba forces the permissions of any newly created directories to be 0555 regardless of what the client requests.Client Request: If a client creates a directory with permissions 0750, Samba will override this and set the directory’s permissions to 0555.Permissions Breakdown:0: No permissions for owner.5: Read and execute permissions for the group.5: Read and execute permissions for others.Enforcement: Samba applies this mode strictly to ensure consistency and security as defined by the administrator.Reference:Samba Force Directory Mode DocumentationNO.30 Which of the following FSMO roles exist? (Choose two.)  File Server  Directory Server  PDC Emulator  RID Master  Global Catalog Flexible Single Master Operations (FSMO) roles, also known as operations master roles, are specialized domain controller tasks in an Active Directory environment. The FSMO roles include:C . PDC EmulatorThe Primary Domain Controller (PDC) Emulator is responsible for synchronizing time and managing password changes.D . RID MasterThe Relative ID (RID) Master allocates blocks of RIDs to each domain controller in the domain.Reference:Microsoft Docs – FSMO RolesNO.31 FILL in BLANKWhat option in sms.conf defines where the data of a file share is stored? (Specify ONLY the option name without any values.) pathExplanation:path Option: This parameter in smb.conf specifies the directory on the server where the shared data is stored.Usage: Within a share definition, the path option points to the actual location on the filesystem that Samba will share.Example Configuration:[example_share] path = /srv/samba/shareImportance: Defining the correct path is crucial for ensuring that the share points to the intended directory with the appropriate data and permissions.Reference:Samba smb.conf man pageNO.32 FILL BLANKWhich command line option instructs smbclient to authenticate using an existing Kerberos token? (Specify ONLY the option name without any values or parameters.) kExplanation:The smbclient command is used to access shared resources on a server running the SMB/CIFS protocol. To authenticate using an existing Kerberos token, the -k option is used. This instructs smbclient to use Kerberos for authentication, assuming that the user already has a valid Kerberos ticket (usually obtained via the kinit command).Example:smbclient //server/share -kReference:smbclient man pageKerberos Authentication with SambaNO.33 FILL BLANKWhat attribute starts the declaration of an object in an LDIF file? (Specify ONLY the attribute name without any values.) dnExplanation:An LDIF (LDAP Data Interchange Format) file is used to represent directory entries in LDAP (Lightweight Directory Access Protocol).Each entry in an LDIF file starts with the dn (Distinguished Name) attribute, which uniquely identifies the entry in the directory.The dn attribute is mandatory and specifies the path to the entry within the LDAP directory.Reference:LDAP documentation: https://ldap.com/ldap-data-interchange-format-ldif/ OpenLDAP LDIF documentation: https://www.openldap.org/doc/admin24/ldif.htmlNO.34 Which of the following commands adds a forward DNS record named fileserver01 pointing to the IPv6 address 2001:db8::190 into the DNS zone samba.private on the Samba 4 server dc1?  net dns -S dc1 -U Administrator addrecord fileserver01.samba.private AAAA 2001:db8::190  dnstool -f dns.tdb add fileserver01.samba.private AAAA 2001:db8::190 -U Administrator  samba-dns dynupdate -S dc1 -U Administrator -h fileserver01.samba.private -t AAAA -V 2001:db8::190  nsupdatesmb -U Administrator //dc1/samba.private/fileserver01 add AAAA 2001:db8::190  samba-tool dns add dc1 samba.private fileserver01 AAAA 2001:db8::190 -U Administrator Command The samba-tool dns add command is used to add DNS records in Samba.Parameters:dc1: Specifies the Samba DNS server.samba.private: The DNS zone.fileserver01: The hostname for the new DNS record.AAAA: Specifies that the record is for an IPv6 address.2001:db8::190: The IPv6 address to be assigned to the hostname.-U Administrator: Specifies the user performing the operation, in this case, the Administrator.Usage: This command properly adds a forward DNS record for fileserver01 with the specified IPv6 address into the samba.private zone on the server dc1.Reference:Samba DNS AdministrationNO.35 What are benefits of registry based Samba configuration compared to file based configuration? (Choose three.)  The registry can be edited remotely without logging into the server.  Registry based configuration supports advanced options which do not exist in smb.conf.  Server processes require less time to start because they do not have to parse the configuration file.  Configuration changes become effective immediately without a daemon reload.  Specific attributes of LDAP objects in Active Directory can be overwritten in the configuration registry. Remote Editing:A . The registry can be edited remotely without logging into the server: One of the benefits of registry-based Samba configuration is that the registry can be edited remotely. This means administrators can make changes without needing to log into the server directly, facilitating easier and more flexible management.Improved Startup Time:C . Server processes require less time to start because they do not have to parse the configuration file: Registry-based configurations can reduce startup time because the Samba server processes do not need to parse a potentially complex smb.conf file. Instead, they access the configuration directly from the registry, which can be faster.Immediate Effect of Configuration Changes:D . Configuration changes become effective immediately without a daemon reload: Changes made in the registry are applied immediately and do not require a daemon reload. This can be very advantageous for administrators who need to make quick adjustments without interrupting the service.Reference:Samba documentationVarious Samba configuration tutorials and best practice guidesNO.36 In a Samba configuration file, which of the following variables represents the domain of the current user?  %D  %r  %d  %G  %w In a Samba configuration file, variables can be used to represent dynamic values.The %D variable represents the domain of the current user.This variable can be used in various configuration directives to customize the behavior of Samba services based on the user’s domain.Reference:Samba variables documentation: https://www.samba.org/samba/docs/current/man-html/smb.conf.5.htmlNO.37 When logging into a windows workstation which is member of an Active Directory domain, which of the following user names refers to the local account bob instead of the domain-wide account bob?  bob@local  %bob%  .bob  “bob”  bob$ When logging into a Windows workstation that is a member of an Active Directory domain, the . prefix is used to specify a local user account rather than a domain account. Therefore, to refer to the local account bob, you would use .bob.Reference:How to Log On to Your Computer if You Are a Domain UserWindows Logon Naming ConventionsNO.38 Which of the following TCP ports is used to provide the SMB protocol without NetBIOS?  133  138  139  386  445 The SMB protocol (Server Message Block) is used for providing shared access to files and printers.Historically, SMB ran on top of NetBIOS over TCP/IP using port 139.SMB can also run directly over TCP/IP without the NetBIOS layer, which uses port 445.Therefore, TCP port 445 is used to provide the SMB protocol without NetBIOS.Reference:Official IANA port numbers: https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml Microsoft documentation on SMB: https://docs.microsoft.com/en-us/windows/win32/fileio/microsoft-smb-protocol-and-cifs-protocol-overviewNO.39 Which smbclient invocation displays a list of the available SMB shares on the remote Samba server FileSrv1?  smbcontrol -L FileSrv1  smbshares –server FileSrv1  smbstatus -S FileSrv1  smbmount -L FileSrv1  smbclient -L FileSrv1 The smbclient command is used to access shared resources on a network that uses the SMB (Server Message Block) protocol. To list the available SMB shares on a remote Samba server, the correct invocation is smbclient -L <server_name>. Here, -L stands for “list” and <server_name> is the name of the Samba server. Therefore, smbclient -L FileSrv1 will list all the available SMB shares on the server named FileSrv1.Reference:smbclient man pageSamba: smbclient CommandNO.40 Which service unifies Linux and Windows account management by allowing a Linux system to include Windows domain users in the Linux user database?  smbpasswdd  sudo  NIS  Winbind  OpenLDAP Winbind: This service is used to unify Linux and Windows account management by allowing a Linux system to include Windows domain users in the Linux user database.Functionality: Winbind enables Linux systems to retrieve user and group information from a Windows NT-based domain or Active Directory.Other Services:smbpasswdd, sudo, NIS, OpenLDAP: These services do not provide the same functionality for unifying account management between Linux and Windows.Reference:Samba Winbind DocumentationNO.41 FILL BLANKWhat service name must be added to a database entry in /etc/nsswitch.conf to include SSSD as a source of information? (Specify ONLY the service name without any parameters.) sssExplanation:Adding SSSD to /etc/nsswitch.conf:To include SSSD (System Security Services Daemon) as a source of information in the /etc/nsswitch.conf file, the service name sss must be added. This is specified without any parameters. The sss service allows the system to retrieve information from various sources, such as LDAP, Kerberos, and others, as configured in SSSD.Reference:SSSD documentationnsswitch.conf configuration guidelinesNO.42 A Samba 4 server provides DNS information regarding an Active Directory Domain. All other DNS information is provided by an additional DNS server. Which of the following solutions ensures that the clients of the Samba server can look up all DNS records including those from the domain?  The additional DNS server is configured in the file /etc/resolv.conf on the Samba server and the option dns forwarder = yes is set in smb.conf.  The search domain of all clients is set to the Active Directory domain name. All clients query only the additional DNS server and not a domain controller.  Both the Samba server and the additional DNS server are configured on the clients. This ensures that the Samba server is listed first in each client’s resolv.conf.  All clients are configured to send DNS queries to the additional DNS server only. The Samba server’s smb.conf contains the option wins dns proxy = yes to provide all domain-related naming information via the NetBIOS name service independently from DNS.  The additional DNS server is configured in the option dns forwarder in smb.conf. All clients query the Samba server for any DNS information. dns forwarder: This smb.conf option specifies the DNS server to which queries should be forwarded if they cannot be resolved locally by the Samba server.Configuration:Add dns forwarder = <additional_DNS_server_IP> to smb.conf on the Samba server.Ensure all clients are configured to query the Samba server for DNS information.Process:Clients send all DNS queries to the Samba server.If the Samba server cannot resolve a query locally, it forwards the request to the additional DNS server.Benefit: This ensures that all DNS records, including those from the Active Directory domain and other DNS information, can be resolved by the clients.Reference:Samba DNS ForwardingNO.43 What is a correct statement about FreeIPA ID views?  ID views are used to modify sudo rules on a per host base.  ID views are the FreeIPA equivalent to Active Directory SIDs.  ID views specify new values for attributes of a POSIX user or group.  ID views provide a consecutive numberspace of UIDs and GIDs for FreeIPA users and groups.  ID views always manage IDs from 32768 to 65536. In FreeIPA, ID views allow administrators to override default POSIX attributes for users and groups. This feature is useful when integrating with other identity management systems, enabling specific attribute values to be used on a per-host basis. This way, different POSIX attributes can be set for the same user or group in different contexts.Reference:FreeIPA: ID ViewsFreeIPA DocumentationNO.44 Which of the following keywords are module types for PAM? (Choose three.)  cache  authentication  password  session  account Pluggable Authentication Modules (PAM) provides a system of libraries that handle the authentication tasks of applications (services) on a Linux system. These libraries are loaded dynamically and can be configured in the /etc/pam.d directory or in /etc/pam.conf. The PAM modules are divided into four types:auth (authentication): This module type is responsible for authenticating the user, setting up user credentials, and initiating a session.account: This module type manages account policies such as password expiration, access restrictions, and checking user permissions.password: This module type handles the updating of authentication tokens, such as passwords.session: This module type manages tasks that need to be performed at the beginning and end of a session, like mounting directories or logging.Reference:Linux PAM DocumentationUnderstanding PAMNO.45 Which of the following commands sets up Samba 4 as an Active Domain Directory Controller for a new domain?  samldap-domainadd  net ads prepare domain  samba-tool domain provision  smbcontrol dcpromo  samba-dcpromo samba-tool domain provision: This command sets up Samba 4 as an Active Directory Domain Controller.Process:Run samba-tool domain provision to start the setup.Follow the prompts to specify the domain name, administrator password, and other required information.Outcome: This command initializes the Samba server as a new domain controller for a new domain, configuring the necessary services and databases.Reference:Samba Active Directory Domain ControllerNO.46 In case the following parameters are set in a Samba file share configuration:create mask = 711force create mode = 750What are the effective permissions of a file created with the permissions 777?  066  027  777  761  751 The effective permissions of a file created with the permissions 777 can be calculated considering the create mask and force create mode.create mask = 711 implies that the permission bits are ANDed with 0711, i.e., only the owner can read, write, and execute.force create mode = 750 implies that certain permission bits are always set, specifically 0750, i.e., read, write, and execute for the owner, and read and execute for the group.The create mask reduces the permissions to 0711, and then force create mode adds the 0750 mask to the result.Original permission: 777 AND with create mask (711): 711 OR with force create mode (750): 751 Thus, the effective permission is 751.Reference:Samba smb.conf man page – create maskNO.47 Which of the following commands terminates all running instances of the Samba daemon handling for SMB shares?  smbcontrol samba shutdown  smbcontrol nmbd shutdown  smbcontrol shutdown  smbcontrol smbd shutdown  smbcontrol cifs stop Samba is a suite of programs that allows SMB/CIFS clients to interact with file and print services on a Linux/UNIX server.smbd is the Samba daemon responsible for handling SMB/CIFS requests.The smbcontrol utility is used to send messages to running Samba daemons.The correct way to terminate all running instances of the Samba daemon handling SMB shares is to send a shutdown message to smbd using the command smbcontrol smbd shutdown.This command ensures that only the smbd processes, which are responsible for handling SMB shares, are terminated without affecting other Samba components like nmbd (NetBIOS name server daemon).Reference:Samba documentation: https://www.samba.org/samba/docs/current/man-html/smbcontrol.1.htmlNO.48 FILL BLANKWhat command checks the Samba configuration file for syntactical correctness? (Specify ONLY the command without any path or parameters.) testparmExplanation:Purpose of the Command: testparm is used to check the Samba configuration file (smb.conf) for syntax errors.CommandRunning testparm will read the smb.conf file, parse it, and display any syntax errors or warnings. This helps ensure that the configuration is valid before restarting the Samba service.Usage Example:Simply execute testparm in the terminal, and it will automatically check the default configuration file.Reference:Samba.org – testparm Loading … Top Lpi 300-300 Courses Online: https://www.examcollectionpass.com/Lpi/300-300-practice-exam-dumps.html --------------------------------------------------- Images: https://free.examcollectionpass.com/wp-content/plugins/watu/loading.gif https://free.examcollectionpass.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2024-10-04 15:26:18 Post date GMT: 2024-10-04 15:26:18 Post modified date: 2024-10-04 15:26:18 Post modified date GMT: 2024-10-04 15:26:18
