Cisco Updated 300-215 Exam Questions and Answers by josephine

The-hoption in theobjdumpcommand displayssection headersof an object file. According to general usage and command-line documentation, and also explained in digital forensics tools discussions in the CyberOps course, the header information includes details about the name, size, VMA, LMA, file offset, and alignment of each section in the object file. This helps analysts understand how data is stored and organized within compiled files during forensic examinations.

The string shown is long, alphanumeric, and includes both uppercase and lowercase letters with numbers—characteristics of Base64 encoding. This format is widely used to obfuscate payloads in malicious scripts, particularly in phishing or malware campaigns. Base64 encoding is also supported by Python and other platforms for data transformation.

Once an incident has occurred, the appropriate course of action is to engage the organization's Incident Response (IR) plan. This is a structured approach to contain, analyze, and eradicate threats before they spread across the network.

The Cisco CyberOps Associate study guide emphasizes:

“Incident response and handling are essential within an organization… The main objective of implementing an incident handling process is to reduce the impact of a cyber-attack, ensure the damages caused are assessed, and implement recovery procedures”.

In particular, the containment phase of IR is focused on isolating the threat and preventing lateral movement or further compromise.

Options such as "root cause" or "attack surface" are relevant at later stages of analysis and mitigation, not immediate containment. Therefore, the correct answer is C.

To prevent macro-based attacks, the Cisco CyberOps study guide emphasizes the importance of limiting execution of unauthorized or unsigned macros. "Requiring that all macros be digitally signed and limiting execution only to those that meet the required trust level is a key mitigation strategy against malicious macros." Additionally, enabling features likeControlled Folder Accesshelps in protecting sensitive directories from unauthorized changes by untrusted applications, including those launched via malicious macros .

These two measures—enforcing signed macro policies and leveraging controlled folder access—directly help in mitigating the risk posed by embedded malicious macros in documents.
