VLAN refers to Virtual Local Area Network. It is a subnetwork that can group together collection of devices on separate physical Local Area Networks. VLANs allow network administrators to group hosts together even if the hosts are not directly connected to the same network switch.
Considering the large number of departments in hospitals, with each departments having functions different from the others, Virtual LANs allows various users(the departments) to be grouped together according to their networking needs, regardless of their actual physical locations. Subdividing the LAN into smaller segments, or VLANs, increases overall reliability, security, and performance, and makes the network easier to maintain.
Because of the largeness of St. Luke's hospitals and their mission of delivering highly reliable and feature-rich advanced network solutions, virtual LAN will help to provide a resilient and scalable network solution within the hospital's budget.
St. Luke should implement virtual LAN that can produce a higher bandwidth with lower-cost, a longer-term model based on servers, networking products and homogenous network components to deliver centralized management of computing across the hospital network.

The file that contains full and incremental back-up information for use with the dump/restore utility is <u>/etc/dumpdates.</u>

<h3>What is dump/restore utility ?</h3>
Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup.
The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.

Answer:
RTT1+ RTT2+..... RTTn
Explanation:
The total estimated time to get the IP address is
RTT1+ RTT2+..... RTTn
Once the IP address is known, O RTT elapses to set up the TCP connection and another O RTT elapses to request and receive the small object. The total response time is
2RTT0+RTT1+RTT2+.....RTTn
