NEW QUESTION # 25
Which of the following lines is missing in the given [printers] share definition?
- A. print admin = Administrator, root, @lpadmin
- B. printcap name = cups
- C. printable = yes
- D. load printers = yes
- E. print script = /usr/bin/lp -d %P %s
Answer: C
Explanation:
In the context of a Samba configuration for printer shares, the [printers] section usually requires the printable = yes directive to indicate that the share is meant for printing. Without this directive, Samba would not treat the share as a printer share, even if other settings like path are configured properly.
The given snippet is:
The line printable = yes is missing and is essential for defining a printer share.

NEW QUESTION # 26
In case the following parameters are set in a Samba file share configuration:
create mask = 711
force create mode = 750
What are the effective permissions of a file created with the permissions 777?
- A. 0
- B. 1
- C. 2
- D. 066
- E. 027
Answer: C
Explanation:
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.

NEW QUESTION # 29
What are benefits of registry based Samba configuration compared to file based configuration? (Choose three.)
- A. Server processes require less time to start because they do not have to parse the configuration file.
- B. Registry based configuration supports advanced options which do not exist in smb.conf.
- C. Configuration changes become effective immediately without a daemon reload.
- D. Specific attributes of LDAP objects in Active Directory can be overwritten in the configuration registry.
- E. The registry can be edited remotely without logging into the server.
Answer: A,C,E
Explanation:
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.

NEW QUESTION # 34
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?
- A. 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.
- B. 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.
- C. 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.
- D. 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.
- E. The additional DNS server is configured in the option dns forwarder in smb.conf. All clients query the Samba server for any DNS information.
Answer: E
Explanation:
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.

Which of the following smb.conf options turns a regular file share into a DFS share?
- A. dfs forward = yes
- B. addfs support = yes
- C. proxy share = yes
- D. follow symlinks = yes
- E. msdfs root = yes
Answer: E
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.

In order to generate an individual log file for each of the machines connecting to a Samba server, which of the following statements must be used in the Samba configuration file?
- A. log file = /var/log/samba/log.%m
- B. log file = /var/log/samba/log.%c
- C. log file = /var/log/samba/log.%M
- D. log file = /var/log/samba/log.%r
- E. log file = /var/log/samba/log.%I
Answer: A
Explanation:
Individual Log Files:
A . log file = /var/log/samba/log.%m: To generate an individual log file for each machine connecting to a Samba server, the %m variable is used in the log file path. This variable represents the machine name of the connecting client. Thus, the configuration line log file = /var/log/samba/log.%m creates a unique log file for each client machine.
