What is the role of containerization in cloud security?

Question

Options

• ATo improve system uptime
• BTo isolate applications and improve security
• CTo allow unregulated access to shared resources
• DTo ensure high network bandwidth

• A
  4% (2)
• B
  94% (50)
• D
  2% (1)

Explanation

Containerization isolates applications and their dependencies into self-contained units (containers), preventing one compromised application from affecting others on the same host - this is its primary security benefit, making B correct. Option A is wrong because uptime is a concern of high availability and redundancy strategies, not containerization itself. Option C is the opposite of what containers do - they restrict access through namespace and cgroup isolation, not permit unregulated sharing. Option D is a networking concern unrelated to containerization's purpose.

Memory tip: Think of containers as "security apartments" - each tenant (app) has their own locked unit and can't wander into a neighbor's space, even though they share the same building (host OS).
