Cloud Security →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that allowing RDP from any IP address (0.0.0.0/0) violates the security best practice of restricting administrative access to trusted IP addresses only. This is because the CloudTrail log entry captures an `AuthorizeSecurityGroupIngress` API call that opens port 3389 to the entire internet, exposing the instance to brute-force attacks and unauthorized access attempts. On the Cisco SCOR / CCNP Security Core 350-701 exam, this scenario tests your ability to interpret cloud infrastructure logs and apply the principle of least privilege to network access controls. A common trap is focusing on the API call itself rather than the destination CIDR block—remember that any rule allowing 0.0.0.0/0 for RDP is an immediate red flag. Memory tip: “Zero-zero-zero-zero means zero trust for RDP.”

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

RDP access is allowed from any IP address (0.0.0.0/0)

The CloudTrail log shows an `AuthorizeSecurityGroupIngress` API call that adds a rule allowing RDP (port 3389) from `0.0.0.0/0`, which means any IP on the internet. This violates the security best practice of restricting administrative access to trusted IP addresses only. Allowing RDP from all sources exposes the instance to brute-force attacks and unauthorized access attempts.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    SSH access is allowed from a single IP

    Why it's wrong here

    The event is for RDP, not SSH.

  • ✗

    Port 22 is open to the internet

    Why it's wrong here

    Port 3389 is open, not 22.

  • ✗

    The user identity is an admin account

    Why it's wrong here

    Admin accounts are expected to make changes.

  • ✓

    RDP access is allowed from any IP address (0.0.0.0/0)

    Why this is correct

    0.0.0.0/0 means all IPs, a major security risk.

    Clue confirmation

    The clue word "best" in the question point toward this answer.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the distinction between the port being open (which is not inherently a violation) versus the source being `0.0.0.0/0` (which is the violation), causing candidates to incorrectly focus on the protocol (RDP vs SSH) rather than the overly permissive source.

Detailed technical explanation

How to think about this question

Under the hood, AWS security group rules are stateful and evaluated at the instance level; a rule allowing `0.0.0.0/0` on port 3389 means any source IP can initiate an RDP session. In real-world scenarios, this is a common misconfiguration that leads to compromise via credential stuffing or exploiting unpatched RDP vulnerabilities, and it is a frequent finding in AWS Trusted Advisor and Security Hub checks.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
