Network Typology point to point Right Ans - Two devices connect
directly
, Network Typology bus Right Ans - All devices connect to a central main
line
Network Typology Ring Right Ans - All devices have two connections
and form an endless ring
Network Typology Star Right Ans - All devices connect to a central point

Cloud - where do I manage the OS Iaas or Paas? Right Ans - Iaas
What do I manage on Paas (2) Right Ans - Application and Data
Name the 3 CIA triades Right Ans - Integrity, Availability and
Confidentiality
What is the CIA Triade Integrity? Right Ans - Detects alteration in
storage, transit and process
What is the CIA Triade Availability? Right Ans - Ensure Authorized
Access, Performance and Backup
Keeping unauthorized users out is not in this triade.
What is the CIA Triade Confidentiality? Right Ans - Protect from
unauthorized access and use, protecting data access in storage, transit and
process
