Answer 1

1. latency does not affect bandwidth, but insufficient bandwidth can reduce latency, insufficient bandwidth leads to link congestion, that means that the equipment buffers will be full and so some packets will be delayed, waiting for their turn to be sent from those buffers, thus increasing latency.

2.High availability important because to ensure data is readily available in situations like server failover, crash etc when you site fails to load because of problems with your database, you risk losing revenues and data center security is the set of policies,precautions and practices adopted to avoid unauthorized access and manipulation of a data center's resources.

3. Confidentiality something being made accessible only to authorized parties integrity not having been altered by an unauthorized party.availability being accessible and usable during a specified time period. threat is potential security violations that can challenge defenses in an attempt to breach privacy and cause harm. Risk is the possibility of loss or harm arising from performing an activity. security controls are countermeasures used to prevent or respond to security threats and to reduce or avoid risk. vulnerability is a weakness that can be exploited either because it is protected by insufficient security controls, for because existing security controls are overcome by an attack. security mechanisms are components comprising a defensive framework that protect IT resources, information, and services. security policy establishes a set of security rules and regulations.

4. Overlapping trust boundaries. since cloud services often share resources among many different customers great care must be taken in establishing boundaries between them. attackers, or the underlying infrastructure as a way to get access to other customers resources VLANs for each entity provides traffic isolation and is ideal method for mitigating this threat.
