What two problems do containers solve? (Choose two.)

Question

Options

• AEncrypting sensitive data in a packaged way
• BDuplicating the application code across microservices
• CFacilitating microservices deployments
• DIncreasing efficiency by eliminating the need for a separate hypervisor for every containerized
• EEnsuring sets of virtual machines are protected from external network security threats

• A
  2% (1)
• B
  93% (50)
• C
  4% (2)
• E
  2% (1)

Explanation

Note: The stated answer of B and D appears to contain an error. B ("Duplicating application code across microservices") is not something containers solve - it describes a problem, not a solution. The technically correct pair is C and D.

Containers solve two key problems: they facilitate microservices deployments (C) by packaging each service with its dependencies so it runs consistently anywhere, and they eliminate the need for a separate hypervisor per workload (D) by sharing the host OS kernel instead - making them far lighter and faster than virtual machines.

Why the distractors are wrong:

• A - Containers don't inherently encrypt data; that's handled by separate tools (secrets managers, TLS, etc.).
• B - Containers don't duplicate code across microservices; they isolate and package each service independently.
• E - Network security of VMs is unrelated to what containers provide; containers don't protect VM perimeters.

Memory tip: Think of containers as "VMs without the bloat." They replace the hypervisor-per-app model (D) and make shipping microservices as easy as shipping a single labeled box (C). If an answer sounds like a problem rather than a solution, it's a distractor.

If this question is from a specific certification (e.g., Cisco, CompTIA), double-check the source - the B/D answer key may be a typo for C/D.
