Best Solaris Interview Questions and Answers

Solaris for Intel users will require the Hardware Compatibility List (HCL) to determine whether their particular system or their peripheral devices are supported. Solaris 10 for Intel runs very fast on modern Pentium-IV systems, meaning that Intel devotees now have a wider choice of operating system, if they don’t want to buy Sun hardware. We herewith compiled some of the Solaris Interview Questions will help to understand the Ruby beginners before attend the interview.

What is umask?

Wide set permissions can be set by using umask which can set write, read and execute permissions on new files created by the user. These settings can be made from the command line to reflect broad settings. It can also be set from the global system settings file. Umask command displays all the settings made with that command.

How can you determine whether a file is setUID?

The easiest way to determine whether a file is setUID or not by checking for files which are owned by the root and after checking for files that are owned by root you can check for s flag files assigned to the user permissions. In the permission table the first s refers to setUID root

Explain about the command prof attr?

Explain the differences between setting files using octal codes and symbolic codes?

The main difference between setting files using octal and symbolic code files is symbolic codes are relative whereas octal codes are numeric codes. These settings will remain unless you change the settings explicitly by using symbolic codes. If group execute access gets executed it automatically removes write access permission.

What is the best solution to avoid large number of groups?

The best solution for not creating large number of groups lies with the system administrator. It is best to use structural group membership which reflects organizational divisions. To manage file access a system admin can use access control lists.

Many Solaris tools are targeted at implementing nonfunctional requirements, such as scalability, availability, security, integrity, and manageability. For example, Sun’s multiprocessing systems are highly available because of their hot-swapping capabilities, meaning that components can be replaced while the system is running—no need for a reboot! Each new release of Solaris brings about changes at the client, server, and system levels. These changes affect users, administrators, and developers in different ways.

Explain about kadmin command?

Local kerbeors services can be managed by administering policies, keytabs and principles by managing the kadmin command. Kadmin.local is used to master KDC and it does not require any authentication.

What is RBAC?

RBAC is introduced into Solaris for managing specific tasks. These specific tasks are based and defined in the administrator profile. It is based on the standard developed by NIST. RBAC is a very important tool for performing multiple tasks. It also separates tasks which require high technical knowledge from low ones.

Describe about Logical Domains and its functions?

LDOMS system administrator center provides resources and links to developers who are trying to install Ldoms technology. It gives you flexibility to group system resources and discrete systems within a computer system physically. It allows you to group system resources physically within its own operating system, identity and resources.

Explain the interoperability features of Solaris?

Solaris UNIX version runs on intel, AMID and SPARC platforms. It has migrated from solely a SPARC platform to include other platforms from leading companies. It provides interoperability across various technologies such as developer products, desktop applications, data center, etc.
