We will be taking a lot of assumptions in this question. Assuming that Landan did not accidentally drop his laptop, as a technician, what I would want to check first is the BIOS settings. There are a couple of issues that can cause this error. These issues may include a boot sector virus that erased the whole hard drive, a bad windows installation, or even a loose cable. Before I check on the BIOS settings, I would request him to unplug any external hard disks. He might have been watching his movies from the hard disk and the disk being connected might be the one causing the error. A wrong boot order in the BIOS settings may be giving priority to another boot source disk like the external hard disk mentioned. I should be able to take Landan through steps that he needs to take to make his hard disk priority. I would also check for corrupt sectors by running the inbuilt CHKDSK tool. If these options don’t work, I would consider checking the hardware itself for further diagnostics.
Hard drive might not be detected due to various reasons. Some problem can be fixed only by the hardware engineer or technical person, few other can be fixed by self by “troubleshooting”. The possible reason could be, BIOS might not have switched on the hard drive so it has not detected. Sometimes data cable might be unplugged.
So you can try replacing one another cable. Another possible reason could be virus. Virus might have corrupted all the data in the hard drive. So anti-virus can be installed to rectify this.
The best practices used in the distribution layer involve the use of HSRP, GLBP, is:
The four best practices used in the distribution layer normally involve the use of certain functions and protocols. These practices ensure efficient and uninterrupted network operations. The most practical ones, from the provided options, would be: c. Using HSRP (Hot Standby Router Protocol), d. Using GLBP (Gateway Load Balancing Protocol), f. Using Layer 3 routing to the core, and g. Summarizing routes.
HSRP is a protocol that allows multiple routers to collaborate in presenting the illusion of a single virtual router to the hosts on the LAN. The inclusion of GLBP helps in balancing the load across a group of redundant routers. Using Layer 3 routing to the core is beneficial in order to maintain versatile connectivity and keep network segmentations to a minimum. Lastly, summarizing routes can minimize the size of the routing table and reduce the overhead on the router's resources.
The answer is:
"Use Layer 3 routing to the core (f)
Summarize routes (g)
Use HSRP (c) or GLBP (d)
Disable trunking in host ports (a)"

Answer:
The following are four best practices used in the distribution layer:
Use HSRP. This provides default gateway redundancy and ensures connectivity for end devices in case of a failure.
Use GLBP. This provides both default gateway redundancy and load balancing for optimal network performance and availability.
Use Layer 3 routing to the core. This eliminates the need for Spanning Tree Protocol (STP) and improves convergence and scalability.
Summarize routes. This reduces the size of the routing table and the amount of routing updates, which enhances network stability and efficiency.
These best practices are based on the Cisco Enterprise Campus Infrastructure document1 and the Cisco Press article on Hierarchical Network Design2.

b. False
In computer systems, there are two types of devices: the input devices and the output devices. The input devices sends data or information to the computer system for processing while the output devices display or reproduce the result of the processing. A device can either be both which is called I/O device.
Best examples for input devices are the mouse and the keyboard. Examples of output are the computer monitors, speakers, and projectors. For I/O device, a USB flash drive is a best example.
The answer to your question is the Paging file which temporarily uses memory from your disk to become part of your virtual memory to remove the load from your RAM (Random Access Memory). This also helps your system to support any application that exceed its physical memory capability.
