The web server reportedly suffered sudden performance degradation and then crashed. Based on the log, a potential cause must be determined before the server is restarted. Which action would prevent the server from experiencing the same problem again?

A. Prevent the password 012345678 from being used by any IP address outside the internal subnet.
B. Investigate other areas of the server because nothing in the logs indicates a problem.
C. Configure IP-reputation blocking through a web application firewall in front of the web server.
D. Set up a web application firewall in front of the web server with request limits per IP address.

正解：D

解説：
The Apache entries show one external address issuing many /admin requests in the same second while incrementing password values. This is automated credential guessing and, at sufficient volume, can exhaust application or server resources. Per-IP request limits at a web application firewall directly throttle the observed behavior before it reaches the server, making A the best preventive action.
Blocking only one password leaves the automation and every other guessed value untouched. The log plainly contains suspicious activity, so C is incorrect. IP-reputation blocking may help when an address is already classified as malicious, but it does not reliably control new or rotating sources; the exhibited property is excessive request rate. CBRFIR objectives 3.1, 3.5, and 4.2 cover interpreting alerts, recommending mitigation, and analyzing Apache/NGINX logs. Cisco describes a WAF as filtering HTTP traffic before it reaches the application in its WAF overview .

質問 # 73

multiple machines behave abnormally. A sandbox analysis reveals malware. What must the administrator determine next?

A. if Patient 0 still demonstrates suspicious behavior
B. if Patient 0 tried to connect to another workstation
C. source code of the malicious attachment
D. if the file in Patient 0 is encrypted

正解：B

解説：
The key goal during lateral movement analysis is to determine whether the malware spread or attempted to spread beyond the initially compromised system. This is crucial for containment and scoping of the incident.
Logs, sandbox behavior, or network activity may show if Patient 0 initiated outbound connections to other systems, potentially propagating malware across the environment.
Correct answer: D. if Patient 0 tried to connect to another workstation.

質問 # 74

A. Generate a Windows executable file.
B. Open the Mozilla Firefox browser.
C. Initiate a connection to 23.1.4.14 over port 8443.
D. Validate the SSL certificate for 23.1.4.14.

正解：C

解説：
This Python script uses a combination of libraries (urllib, zlib, base64, and ssl) to:
* Disable SSL certificate verification (ssl.CERT_NONE and check_hostname=False).
* Construct a custom HTTPS opener with the specified SSL context.
* Add a forged User-Agent header to mimic Internet Explorer 11.
* Connect to the URL https://23.1.4.14:8443.
* Download and execute base64-encoded and zlib-compressed content from that URL using:
exec(zlib.decompress(base64.b64decode(...).read()))
This shows a classic example of:
* Downloading payloads from a remote server (23.1.4.14:8443).
* Avoiding detection by disabling SSL verification.
* Executing the payload dynamically with exec() after decoding and decompressing.
The main goal is clearly to initiate a connection to a remote command-and-control (C2) server on port 8443 and download/execute additional code.
Hence, the correct answer is: A. Initiate a connection to 23.1.4.14 over port 8443.

質問 # 75

Refer to the exhibit. A network administrator creates an Apache log parser by using Python. What needs to be added in the box where the code is missing to accomplish the requirement?

A. r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}'
B. r'\d(1,3),\d(1.3),\d{13}.df{1,3}'
C. r''\b{1-9}[0-9}\b'
D. r'*\b'

正解：A

解説：
The goal of the given Python code is to parse an Apache access log and extract IP addresses using regular expressions (regex). In this context, the most appropriate regex pattern to extract IPv4 addresses from log data is:
* r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}'
This pattern matches typical IPv4 addresses, where each octet consists of 1 to 3 digits separated by periods.
For example, it matches addresses like192.168.1.1or10.0.0.123. The pattern uses:
* \d{1,3}to capture between 1 and 3 digits,
* \.to match the dot (escaped since.is a special character in regex),
* repeated 4 times with proper separation to form the full IPv4 structure.
Options A, B, and C either include incorrect syntax, improper escape sequences, or do not represent a valid IP address pattern.
This type of log analysis and pattern extraction is described in the Cisco CyberOps Associate curriculum under basic scripting and automation techniques used in log and artifact analysis.
