Yu must decide hw t best divide yur time. Nte: If the administratr r rt passwrd is set wrng n the devices and the right ne is nt dcumented smewhere, the judges will nt be able t mark yur wrk and yu will lse pints. Yu have t cnfirm each task f yur dings n the crrespnding cnfirmatin blck. This means if yu have prcessed the task check the apprpriate checkbx.

AFTERWARDS YOU MAY WORK IN ANY ORDER. PLAN CAREFULLY! 1.3 DESCRIPTION OF PROJECT AND TASKS Yu will wrk fr the IT Department within a small technlgy cmpany which is called Black Mesa Inc.. Yur cmpany seat is cnnected thrugh a Private Line t the data centre which hsts all the necessary public services fr the cmpany Client The client is preinstalled with the cmpany default cnfiguratin Server The cmpany has ne Windws Server 2008 R2 in- huse which is respnsible fr data sharing, hsting the intranet web applicatin and ffers terminal services. The server acts als as infrastructure server based n an active directry service. On this server the cmpany needs additinal a research test VM. The utsurced Linux server is respnsible fr hsting the internet page, the address assignment and webcaching. This Server is cnnected thrugh a Private Line t the netwrk f Black Mesa. The internet page has t be published by the Linux firewall t the internet Netwrk Build the netwrk which is shwn in the Part 3. Use the same address and cnfiguratin infrmatin Dcumentatin All wrking steps must be dcumented n a sheet f paper. Chse the level f detail by yurself.
