Another is that it provides an environment for the development and execution of programs. With an increased number of processors, there is a considerable increase in throughput. It can also save more money because they can share resources. Finally, overall reliability is increased as well. A kernel is the core of every operating system. It connects applications to the actual processing of data. It also manages all communications between software and hardware components to ensure usability and reliability. Real-time systems are used when rigid time requirements have been placed on the operation of a processor. It has well defined and fixed time constraints. Virtual memory is a memory management technique for letting processes execute outside of memory. This is very useful especially is an executing program cannot fit in the physical memory. The main objective of multiprogramming is to have a process running at all times.

32 Most Commonly Asked Windows Server Administrator Interview Questions (With Answers)
With this design, CPU utilization is said to be maximized. In a Time-sharing system, the CPU executes multiple jobs by switching among them, also known as multitasking. This process happens so fast that users can interact with each program while it is running. It is the most common type of multiple-processor systems. In this system, each processor runs an identical copy of the operating system, and these copies communicate with one another as needed. Server systems can be classified as either computer-server systems or file server systems. In the first case, an interface is made available for clients to send requests to perform an action. In the second case, provisions are available for clients to create, access and update files.

In asymmetric clustering, a machine is in a state known as hot standby mode where it does nothing but to monitor the active server. A thread is a basic unit of CPU utilization. In general, a thread is composed of a thread ID, program counter, register set, and the stack. FCFS stands for First-come, first-served. It is one type of scheduling algorithm. Implementation is managed by a FIFO queue. RR round-robin scheduling algorithm is primarily aimed for time-sharing systems. A circular queue is a setup in such a way that the CPU scheduler goes around that queue, allocating CPU to each process for a time interval of up to around 10 to milliseconds. Deadlock situations occur when four conditions occur simultaneously in a system: Mutual exclusion; Hold and Wait; No preemption; and Circular wait. It gets its name from a banking system wherein the bank never allocates available cash in such a way that it can no longer satisfy the needs of all of its customers.

One is that it depends on how often a deadlock is likely to occur under the implementation of this algorithm. The other has to do with how many processes will be affected by deadlock when this algorithm is applied. Logical address refers to the address that is generated by the CPU. On the other hand, physical address refers to the address that is seen by the memory unit. With dynamic loading, a routine is not loaded until it is called. This method is especially useful when large amounts of code are needed in order to handle infrequently occurring cases such as error routines. Overlays are used to enable a process to be larger than the amount of memory allocated to it.

The basic idea of this is that only instructions and data that are needed at any given time are kept in memory. Paging is a memory management scheme that permits the physical address space of a process to be noncontiguous. It avoids the considerable problem of having to fit varied sized memory chunks onto the backing store. Fragmentation is memory wasted. It can be internal if we are dealing with systems that have fixed-sized allocation units, or external if we are dealing with systems that have variable-sized allocation units.

During regular intervals that are set by the operating system, processes can be copied from main memory to a backing store, and then copied back later. Swapping allows more operations to be run that can fit into memory at one time. A socket provides a connection between two applications. Each endpoint of a communication is a socket. Direct Access method is based on a disk model of a file, such that it is viewed as a numbered sequence of blocks or records. It allows arbitrary blocks to be read or written. Direct access is advantageous when accessing large amounts of information. Thrashing refers to an instance of high paging activity. This happens when it is spending more time paging instead of executing. The best paging size varies from system to system, so there is no single best when it comes to page size. There are different factors to consider in order to come up with a suitable page size, such as page table, paging time, and its effect on the overall efficiency of the operating system.

Typically, the different attributes for a file structure are naming, identifier, supported file types, and location for the files, size, and level of protection. Root partition is where the operating system kernel is located. It also contains other potentially important system files that are mounted during boot time. This prevents conflicts whenever such devices are incorporated in a systems unit. It is based on a file-representation structure known as vnode, which contains a numerical designator needed to support network file systems.

Citation Is running these commands as root a good or bad idea? Running everything as root is bad due to two major issues. The first is risk. Nothing prevents you from making a careless mistake when you are logged in as root. The second reason is security. Having access to root means you already have one half of the working set of admin credentials. What is the difference between rm and rm -rf?

Windows System Administrator Interview Question And Answer
There are no safeguards against failure. Citation RAID 1: A popular disk subsystem that increases safety by writing the same data on two drives. Also, if one drive fails, the second drive is used, and the failed drive is manually replaced. After replacement, the RAID controller duplicates the contents of the working drive onto the new one. RAID 5: A disk subsystem that increases safety by computing parity data and increasing speed. RAID 5 does this by interleaving data across three or more drives striping. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.

RAID 6 does not have a performance penalty for reading operations, but it does have a performance penalty on write operations because of the overhead associated with parity calculations. It requires a minimum of four disks, and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. If two disks in the same mirrored pair fail, all data will be lost because there is no parity in the striped sets. Citation Which port is used for the ping command? The ping command uses ICMP. What is the difference between a router and a gateway? What is the default gateway? Router describes the general technical function layer 3 forwarding , or a hardware device intended for that purpose, while gateway describes the function for the local segment providing connectivity to elsewhere. You could also state that you "set up a router as a gateway. The term default gateway is used to mean the router on your LAN, which has the responsibility of being the first point of contact for traffic to computers outside the LAN.

Explain the boot process for Linux. Kernel messages are always stored in the kmsg buffer, visible via the dmesg command. What is the difference between a symbolic link and a hard link? Updated Aug 30, Editor's note: this answer original said 'a hard link is a mirror copy of the original file,' which is not accurate. Thank you to Bruce Bowen for providing the following answer: A hard link is a directory reference to the same inode that the first directory entry refers to, and the inode is updated to increase the reference count to know there is a new link to the data.
https://pinterest.com/gwj2310/bible-study/
Python Interview Questions For System Administrator
This means that when a file is 'deleted', the directory is updated to remove the file name and the inode for the data has the reference count decremented. The data of the file won't be freed unless the reference count goes to 0. Since inodes are unique for each file system, hard links can't cross file systems. Soft links create a way to for a directory entry to say "the file information is really stored in another directory entry".

24 Sysadmin Job Interview Questions You Should Know | Medicoguia.com
Soft links break if the 'another directory entry' is deleted. So a 'user' way to describe the difference between a hard and soft link is that a hard link is a link to the file data and a soft link is a link to another file name. How do you change kernel parameters? What kernel options might you need to tune? After making the changes, save the file and run the sysctl -p command. These virtual files have unique qualities. Most of them are listed as zero bytes in size. How do you run a script as another user without their password? Have you been compromised? The toor user is an alternative superuser account, where toor is root spelled backward. It is intended to be used with a non-standard shell, so the default shell for root does not need to change. This purpose is important.

7 Systems Administrator Interview Questions And Answers
Advanced questions Here are the even more difficult questions you may encounter: How does tracert work and what protocol does it use? The command tracert—or traceroute depending on the operating system—allows you to see exactly what routers you touch as you move through the chain of connections to your final destination. What is the main advantage of using chroot? When and why do we use it? An advantage of having a chroot environment is that the filesystem is isolated from the physical host, since chroot has a separate filesystem inside your filesystem. A chroot jail lets you isolate a process and its children from the rest of the system. The idea is that you create a directory tree where you copy or link in all of the system files needed for the process to run. Citation How do you protect your system from getting hacked? By following the principle of least privileges and these practices: Encrypt with public keys, which provides excellent security. Enforce password complexity.

How To Prepare For A Sysadmin Interview
Understand why you are making exceptions to the rules above. Review your exceptions regularly. Hold someone to account for failure. It keeps you on your toes. Citation What is LVM, and what are the advantages of using it? LVM, or Logical Volume Management, uses a storage device management technology that gives users the power to pool and abstract the physical layout of component storage devices for easier and flexible administration. Using the device mapper Linux kernel framework, the current iteration LVM2 can be used to gather existing storage devices into groups and allocate logical units from the combined space as needed.

Windows Admin Interview Questions
What are sticky ports? They allow you to set up your network so that each port on a switch only permits one or a number that you specify computer to connect on that port, by locking it to a particular MAC address. Explain port forwarding? When trying to communicate with systems on the inside of a secured network, it can be very difficult to do so from the outside—and with good reason. Therefore, the use of a port forwarding table within the router itself, or other connection management device, can allow specific traffic to automatically forward to a particular destination. For example, if you had a web server running on your network and you wanted to grant access to it from the outside, you would set up port forwarding to port 80 on the server in question.

Windows System Administrator Interview Question And Answer - Technet2u
Please note, it is usually not recommended to allow access to a server from the outside directly into your network. What is a false positive and false negative in the case of IDS? When the Intrusion Detection System IDS device generates an alert for an intrusion which has actually not happened, this is false positive. If the device has not generated any alert and the intrusion has actually happened, this is the case of a false negative. This is a fork bomb. It breaks down as follows: : defines the function, with : as the function name, and the empty parenthesis shows that it will not accept any arguments. The best way to protect a multi-user system is to use Privileged Access Management PAM to limit the number of processes a user can use. The biggest problem with a fork bomb is the fact it takes up so many processes. So, we have two ways of attempting to fix this if you are already logged into the system.

An OOM killer first has to select the best process es to kill. Best here refers to the process which will free up the maximum memory upon being killed, and is also the least important to the system. The primary goal is to kill the least number of processes to minimize the damage done, and at the same time maximize the amount of memory freed. In the end, the system administration career path boils down to your interest in working with servers and solving cool problems. Now, I would say go ahead and achieve your dream path. I'm highly passionate about open source, cloud, security and networking technologies.
