NEW QUESTION # 27
Which parameter within a share definition in the Samba configuration makes Samba only show files and directories on a file share which a user can access?
- A. hide unreadable = yes
- B. browse mask = 000
- C. valid files = read,write
- D. browseable = readable
- E. display mode = 100
Answer: A
Explanation:
hide unreadable: This smb.conf option ensures that only files and directories that the user has permissions to access are visible in the file share.
Functionality: When set to yes, files and directories that the user cannot read (due to permissions) will be hidden from their view.
Security and Usability: This helps in enhancing both security and usability by preventing users from seeing files they cannot access, reducing clutter and potential confusion.
Example Configuration:
[example_share] hide unreadable = yes

What is a correct statement about FreeIPA ID views?
- A. ID views always manage IDs from 32768 to 65536.
- B. ID views are the FreeIPA equivalent to Active Directory SIDs.

NEW QUESTION # 33
When using rsync to synchronize the SYSVOL share's contents between multiple Samba servers, which of the following precautions should be taken? (Choose three.)
- A. Synchronize from the domain controller which is the PDC emulator to the other domain controllers.
- B. Overwrite the permissions of all files in the SYSVOL directory to be readable by root only after each sync.
- C. Make sure that the SYSVOL share is active on only one domain controller.
- D. Make the SYSVOL share read only on all domain controllers but the one used as synchronization source.
- E. Make sure to make all changes to GPOs on the domain controller which is the replication source.
Answer: A,D,E
Explanation:
When using rsync to synchronize the SYSVOL share's contents between multiple Samba servers, it's essential to ensure data consistency and avoid conflicts. The following precautions should be taken:
A . Synchronize from the domain controller which is the PDC emulator to the other domain controllers.
The PDC emulator is typically the authoritative source for certain domain-wide operations, making it the best source for SYSVOL synchronization.
C . Make the SYSVOL share read only on all domain controllers but the one used as synchronization source.
This prevents changes on other domain controllers that could cause inconsistencies.
E . Make sure to make all changes to GPOs on the domain controller which is the replication source.
Ensuring that all Group Policy Objects (GPOs) changes are made on the source controller prevents conflicts and ensures that all controllers have the latest configuration.

NEW QUESTION # 34
How is the Global Catalog of an Active Directory domain accessed?
- A. Through LDAP queries to the ports 3268 (plain text) and 3269 (TLS encrypted).
- B. Through LDAP queries to the base dn CN=GC in the standard LDAP directory.
- C. Through SRV records in the DNS sub zone _msgc in the domain's DNS zone.
- D. Through the share GCS SMB which is available on each domain controller.
- E. Through GCS records in the DNS sub zone _gc in the domain's DNS zone.
Answer: A
Explanation:
Global Catalog: The Global Catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multi-domain Active Directory forest.
Access Method: It is accessed through LDAP queries to specific ports:
Port 3268: For plain text (unencrypted) LDAP queries.
Port 3269: For LDAP queries encrypted with TLS.
Other Options:
GCS SMB share, GCS records, SRV records, CN=GC in LDAP: These do not provide the correct method to access the Global Catalog.

NEW QUESTION # 36
Which of the following statements is true about raw printing with Samba?
- A. Any printed file, e.g. an office document, is submitted to the printer without any further processing in exactly the same bit sequence as it is stored on disk.
- B. Printing jobs are always submitted to Samba in raw postscript.
- C. Samba converts printer-specific jobs to raw data to make them printable on an arbitrary printer.
- D. Print jobs are submitted as vector files, including font files, which are rendered and printed by Samba.
- E. Printing jobs are rendered on the client and passed on to the printer by Samba.
Answer: E
Explanation:
Client-Side Rendering: In Samba, raw printing means that the client machine renders the print job, which includes converting it to a printer-ready format.
Transmission to Printer: This rendered print job is then sent to the Samba server without further processing or alteration. Samba acts merely as a pass-through, sending the job directly to the printer.
Advantages: This method offloads the rendering process from the server to the client, which can be beneficial in environments with diverse printer types and models, reducing the processing load on the server.
Conclusion: Thus, the correct answer is that printing jobs are rendered on the client and passed on to the printer by Samba.

NEW QUESTION # 37
The [homes] section of smb.conf contains the parameter browseable = no. What are the resulting consequences? (Choose two.)
- A. When browsing the Samba server, there is no visible share called homes.
- B. When browsing the Samba server, users can open the homes share but they cannot see the content of their home directories.
- C. The homes share can be directly accessed by specifically opening this share by its UNC path.
- D. If the Samba server is part of an Active Director/ Domain, only users in the qroup Se3rowsingUsers can browse the homes share.
- E. When browsing the Samba server, there is no visible share named after the current user.
Answer: C,E
Explanation:
When browseable = no is set in the [homes] section of smb.conf, it prevents the share from appearing in the list of available shares when users browse the server. However, users can still access their home directories if they specify the correct UNC path directly.
A . When browsing the Samba server, there is no visible share named after the current user.
The share will not appear in the list of shares visible to the user during browsing.
D . The homes share can be directly accessed by specifically opening this share by its UNC path.
Users can still access the share by directly typing the path in the form \\servername\username.

Which command line option instructs smbclient to authenticate using an existing Kerberos token? (Specify ONLY the option name without any values or parameters.)
Answer:
Explanation:
k
Explanation:
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 -k

NEW QUESTION # 40
Which of the following smb.conf options turns a regular file share into a DFS share?
- A. addfs support = yes
- B. proxy share = yes
- C. dfs forward = yes
- D. msdfs root = yes
- E. follow symlinks = yes
Answer: D
Explanation:
DFS (Distributed File System): This allows for the organization of shared files on multiple servers in a distributed file system.
msdfs root = yes: This option in the Samba configuration file (smb.conf) enables a share to be a DFS root. This means the share can provide access to multiple other shares possibly located on different servers, creating a single point of access.
Functionality: When enabled, users accessing this DFS root can be redirected transparently to the actual location of the shared files, which might be spread across different servers.
Setup: To configure a DFS root, add msdfs root = yes to the specific share definition in smb.conf.

What attribute starts the declaration of an object in an LDIF file? (Specify ONLY the attribute name without any values.)
Answer:
Explanation:
dn
Explanation:
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.
