How is DNS tunneling used to exfiltrate data out of a corporate network?
Answer(s): B
Domain name system (DNS) is the protocol that translates human-friendly URLs, such as securitytut.com, into IP addresses, such as 183.33.24.13. Because DNS messages are only used as the beginning of each communication and they are not intended for data transfer, many organizations do not monitor their DNS traffic for malicious activity. As a result, DNS-based attacks can be effective if launched against their networks. DNS tunneling is one such attack.An example of DNS Tunneling is shown below:The attacker incorporates one of many open-source DNS tunneling kits into an authoritative DNS nameserver (NS) and malicious payload.2. An IP address (e.g. 1.2.3.4) is allocated from the attacker's infrastructure and a domain name (e.g. attackerdomain.com) is registered or reused. The registrar informs the top-level domain (.com) nameservers to refer requests for attackerdomain.com to ns.attackerdomain.com, which has a DNSrecord mapped to 1.2.3.43. The attacker compromises a system with the malicious payload. Once the desired data is obtained, the payload encodes the data as a series of 32 characters (0-9, A-Z) broken into short strings (3KJ242AIE9, P028X977W,...).4. The payload initiates thousands of unique DNS record requests to the attacker's domain with each string as a part of the domain name (e.g. 3KJ242AIE9.attackerdomain.com). Depending on the attacker's patience and stealth, requests can be spaced out over days or months to avoid suspicious network activity.5. The requests are forwarded to a recursive DNS resolver. During resolution, the requests are sent to the attacker's authoritative DNS nameserver,6. The tunneling kit parses the encoded strings and rebuilds the exfiltrated data.

Which Cisco AMP file disposition valid?
When using Cisco AMP for Networks which feature copies a file to the Cisco AMP cloud for analysis?
Spero analysis examines structural characteristics such as metadata and header information in executable files. After generating a Spero signature based on this information, if the file is an eligible executable file, the device submits it to the Spero heuristic engine in the AMP cloud. Based on the Spero signature, the Spero engine determines whether the file is malware.
https://www.cisco.com/c/en/us/td/docs/security/firepower/60/configuration/guide/fpmc-config- guidev60/Reference_a_wrapper_Chapter_topic_here.html-> Spero analysis only uploads the signature of the (executable) files to the AMP cloud. It does not upload the whole file. Dynamic analysis sends files to AMP ThreatGrid. Dynamic Analysis submits (the whole) files to Cisco Threat Grid (formerly AMP Threat Grid). Cisco ThreatGrid runs the file in a sandbox environment, analyzes the file's behavior to determine whether the file is malicious, and returns a threat score that indicates the likelihood that a file contains malware. From the threat score, you can view a dynamic analysis summary report with the reasons for the assigned threat score. You can also look in Cisco Threat Grid to view detailed reports for files that your organization submitted, as well as scrubbed reports with limited data for files that your organization did not submit. Local malware analysis allows a managed device to locally inspect executables, PDFs, office documents, and other types of files for the most common types of malware, using a detection rule set provided by the CiscoTalos Security Intelligence and Research Group (Talos). Because local analysis does not query theAMP cloud,and does not run the file, local malware analysis saves time and system resources. -> Malware analysis does not upload files to anywhere, it only checks the files locally. There is no sandbox analysis feature, it is just a method of dynamic analysis that runs suspicious files in a virtual machine.

Which statement is true about using default environment variables? The environment variables can be read in workflows using the ENV: variable_name syntax. The environment variables created should be prefixed with GITHUB_ to ensure they can be accessed in workflows The environment variables can be set in the defaults: sections of the workflow The GITHUB_WORKSPACE environment variable should be used to access files from within the runner.Correct answer: The statement "The GITHUB_WORKSPACE environment variable should be used to access files from within the runner." is true. Why the others are false:

Why this is correct
Question 7:
Question 104:
clustering keys
Q23: Fabric Admin is correct. Because Domain admin cannot create domains. Only Fabric Admin can among the given options. Q51: Wrapping @pipeline.parameter.param1 inside {} will return a string. But question requires the expression to return Int, so correct answer should be @pipeline.parameter.param1 (no {})
Question 62:
ZDX

date = dbutils.notebooks.getParam("date")
dbutils.notebook.run
Question 528:
Question 23:The correct answer is Domain admin (option B), not Fabric admin.
Question 2:For question 2, the key concept is the Longest Prefix Match. Routers pick the route whose subnet mask is the most specific (largest prefix length) that still matches the destination IP. From the options:
Question 129:Correct answer: CNAME

This is very interesting
Are these the same questions you have to pay for in ExamTopics?
For Question 7 - while the answer description indicates the correct answer, the option no. mentioned is incorrect. Nice and Comprehensive. Thankyou
This is very good and accurate. Explanation is very helpful even thou some are not 100% right but good enough to pass.
The DP-900 exam can be tricky if you aren't familiar with Microsoft’s specific cloud terminology. I used the practice questions from free-braindumps.com and found them incredibly helpful. The site breaks down core data concepts and Azure services in a way that actually mirrors the real test. As a resutl I passed my exam.
