Domain 1: Security Monitoring and Analysis (20 Questions)
[SCREENSHOT: SIEM Dashboard - Splunk Enterprise Security Overview Panel]
Q1: The SIEM dashboard displays four critical security events: (1) Failed login attempts
from IP 192.168.1.45 to Domain Controller (Severity: High, Count: 150 in 5 min), (2)
Malware detection on workstation WS-7834 (Severity: Critical), (3) Firewall blocked
external scan from 203.0.113.50 (Severity: Medium), and (4) Successful VPN login from
unusual geolocation (Severity: Low). Based on standard security operations
prioritization, which event requires immediate escalation to the Incident Response
team?
A. The firewall blocked external scan, as external reconnaissance always precedes
active attacks
B. The successful VPN login from unusual geolocation, as compromised credentials are
the primary attack vector
C. The malware detection on workstation WS-7834, as active endpoint compromise
indicates a breach in progress [CORRECT]
,D. The failed login attempts, as brute force attacks against Domain Controllers threaten
authentication infrastructure
Correct Answer: C
Rationale: The malware detection represents an active compromise requiring
immediate containment. In security operations, confirmed active threats (Critical
severity) take precedence over potential or attempted attacks. The endpoint detection
indicates successful execution of malicious code, representing a confirmed security
incident per NIST SP 800-61. Option A misinterprets reconnaissance as active
compromise; Option B overweights low-severity alerts despite unusual location being
common for remote workers; Option D, while concerning, represents an attempted
attack that has not yet succeeded. The 150 failed logins, while suspicious, indicate the
attacker's lack of success, whereas malware detection confirms system compromise
and potential lateral movement capability.

Q2: The IDS alert shows: ET TROJAN Possible WannaCry Ransomware
Activity (M2) with source IP 10.0.5.23 (internal) to destination 185.220.101.44
(external) on port 443. The payload analysis reveals encrypted SMB traffic with
distinctive byte patterns matching EternalBlue exploit signatures. The internal host is a
file server in the Finance department. What is the most appropriate immediate action?
,A. Isolate the internal host from the network immediately and initiate forensic imaging
[CORRECT]
B. Block the external IP at the perimeter firewall and continue monitoring the internal
host
C. Update IDS signatures and wait for additional alerts before taking action
D. Notify the Finance department to backup their files and prepare for potential
downtime
Correct Answer: A
Rationale: The alert indicates active ransomware propagation using EternalBlue
(CVE-2017-0144), the exploit behind WannaCry. The internal file server communicating
externally with ransomware C2 infrastructure represents a critical active breach.
Immediate network isolation prevents lateral movement and encryption spread, aligning
with WGU D483's containment procedures and NIST SP 800-61 Rev. 2 containment
strategies. Option B addresses only the external component while leaving the
compromised internal asset active; Option C violates the principle of immediate
containment for active malware; Option D delays containment and risks data
destruction. The file server role increases priority due to potential data exfiltration and
business impact.

, Q3: The firewall logs show repeated connection attempts from internal subnet
10.20.30.0/24 to external IP 91.203.5.100 on TCP/4444 (Metasploit default) with
application identified as "unknown-tcp" and action "allow." The connections occur every
15 minutes, 24 bytes transferred each session, and the destination is flagged in threat
intelligence as a Cobalt Strike C2 server. Which conclusion is most accurate?
A. This represents legitimate administrative remote access using an alternative port
B. This indicates compromised internal hosts beaconing to command and control
infrastructure [CORRECT]
C. This is likely a false positive due to the small data transfer volume
D. This represents normal software update traffic on a non-standard port
Correct Answer: B
Rationale: The evidence strongly indicates C2 beaconing: (1) TCP/4444 is Metasploit's
default reverse shell port, (2) Regular 15-minute intervals are characteristic of
beaconing patterns, (3) Minimal data transfer (24 bytes) suggests keep-alive/check-in
traffic, (4) Destination IP matches known Cobalt Strike infrastructure in threat
intelligence, and (5) "unknown-tcp" application classification indicates non-standard
protocol usage. WGU D483 emphasizes recognizing C2 patterns through temporal
analysis and threat intelligence correlation. Option A ignores the threat intelligence
match and suspicious port; Option C misinterprets small transfer volume (beaconing is
intentionally minimal); Option D fails to recognize the threat indicators. Immediate host
investigation and containment are required.
