Which of the following are symmetric encryption algorithms? Select all that apply.

Incorrect
  1. A.AES
  2. B.3DES
  3. C.RSA
  4. D.Diffie-Hellman
  5. E.ChaCha20

Symmetric means one shared key: AES, 3DES, and ChaCha20 — the last one should have been selected. RSA is asymmetric key pairs, and Diffie-Hellman is key exchange, not encryption.

Which controls meaningfully reduce phishing risk? Select all that apply.

Incorrect
  1. A.Regular user awareness training
  2. B.Email filtering with link and attachment scanning
  3. C.Multi-factor authentication on all accounts
  4. D.Rotating passwords every two weeks
  5. E.Blocking all attachments organization-wide

Training and filtering cut the clicks; MFA is what saves you after the click — that one should have been selected. Aggressive rotation just produces sticky notes, and blocking every attachment blocks the business.

What belongs in an incident response plan? Select all that apply.

Correct
  1. A.Defined roles and an up-to-date contact list
  2. B.Containment and eradication procedures
  3. C.A blameless lessons-learned review
  4. D.Permanent admin access for all responders
  5. E.Evidence preservation and chain of custody

People, procedures, evidence, and the review afterward. Standing admin access for everyone is an incident waiting to happen, not a way to respond to one.

Understand why,
not only what.

CompTIA A+ questions test how you apply knowledge in real situations. After every answer, you are provided with a clear rationale so you can understand the reasoning, learn from mistakes, and recognize it when it appears again.

“I'm hands-on with learning but doing the 10 questions a day and actually working on my own desktop does create a situation where you are retaining information and knowledge. Not only are these real time issues, the app also explain in detail the reason said issue occurred with whatever category of study you choose. I now feel more warm and fuzzy so to speak when it comes to CompTIA A+ and Networking”
