200-201 Security Monitoring Practice Question

This 200-201 practice question tests your understanding of security monitoring. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Which TWO protocols are commonly used for remote administration and should be monitored for unauthorized access?

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

SSH (port 22)

SSH (port 22) is correct because it provides encrypted remote administration, making it a common target for brute-force attacks and unauthorized access attempts. RDP (port 3389) is correct because it is the primary protocol for remote GUI administration on Windows systems and is frequently exploited via credential stuffing or vulnerability scanning. Both protocols should be monitored for anomalous login patterns and unauthorized access.

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.

  • Telnet (port 23)

    Why it's wrong here

    Telnet is unencrypted and rarely used for secure administration; SSH is preferred.

  • SSH (port 22)

    Why this is correct

    SSH is a secure remote administration protocol.

    Read the scenario before looking for a memorised answer.

  • RDP (port 3389)

    Why this is correct

    RDP is a common remote desktop protocol for Windows.

    Related concept

    Read the scenario before looking for a memorised answer.

  • SNMP (port 161/162)

    Why it's wrong here

    SNMP is for network management, not remote administration.

  • FTP (port 20/21)

    Why it's wrong here

    FTP is for file transfer, not remote administration.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the distinction between protocols used for remote administration (SSH, RDP) versus those used for network management (SNMP) or file transfer (FTP), and candidates may mistakenly include Telnet because it is historically associated with remote access, despite its lack of encryption and modern disuse.

Detailed technical explanation

How to think about this question

SSH uses a client-server model with public-key cryptography for authentication and session encryption, typically leveraging the Diffie-Hellman key exchange. RDP uses the T.128 protocol stack and supports Network Level Authentication (NLA) for pre-authentication; unauthorized access often targets weak passwords or unpatched vulnerabilities like BlueKeep (CVE-2019-0708). In real-world SOC monitoring, failed login thresholds and geolocation anomalies are key indicators of brute-force attacks against these services.

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 200-201 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.
