A security analyst is writing a shell script to identify IP addresses from the same country. Which of the following functions would help the analyst achieve the objective?

  1. function w() { info=$(ping -c 1 $1 | awk -F "/" `END{print $1}') && echo "$1 | $info" }
  2. function x() { info=$(geoiplookup $1) && echo "$1 | $info" }
  3. function y() { info=$(dig -x $1 | grep PTR | tail -n 1 ) && echo "$1 |
    $info" }
  4. function z() { info=$(traceroute -m 40 $1 | awk `END{print $1}') && echo "$1 | $info" }

Answer(s): B

Explanation:

Option B is correct because geoiplookup maps an IP address to geographic location data, enabling country-based identification. A) uses ping parsing which yields latency, not location. C) dig -x performs reverse DNS and PTR parsing, which provides domain names, not country information. D) traceroute shows hop addresses and path details, not country assignment. Incorrect explanations: A) only measures reachability; no geolocation. C) PTR data does not reliably indicate country. D) traceroute outputs network path, not country of origin. Correct — geoiplookup provides country inference from IP, aligning with objective to identify IPs from the same country.



A security analyst obtained the following table of results from a recent vulnerability assessment that was conducted against a single web server in the environment:



Which of the following should be completed first to remediate the findings?

  1. Ask the web development team to update the page contents
  2. Add the IP address allow listing for control panel access
  3. Purchase an appropriate certificate from a trusted root CA
  4. Perform proper sanitization on all fields

Answer(s): D

Explanation:

Option D is correct because performing proper sanitization on all fields directly mitigates common input handling vulnerabilities (e.g., XSS, SQL injection) identified by vulnerability assessments, addressing the root cause and reducing attack surface. Incorrect — A: Updating page contents may fix display issues but does not address input validation vulnerabilities. Incorrect — B: IP allow listing for control panels reduces exposure but does not remediate insecure input handling and can introduce access control risks. Incorrect — C: Acquiring a certificate affects TLS trust but does not fix input validation flaws or sanitize user-provided data.



While reviewing web server logs, an analyst notices several entries with the same time stamps, but all contain odd characters in the request line. Which of the following steps should be taken next?

  1. Shut the network down immediately and call the next person in the chain of command.
  2. Determine what attack the odd characters are indicative of.
  3. Utilize the correct attack framework and determine what the incident response will consist of.
  4. Notify the local law enforcement for incident response.

Answer(s): B

Explanation:

Option B is correct because identifying the specific attack indicated by unusual request line characters is a key proactive step in triage and incident classification, enabling appropriate containment, eradication, and recovery actions within an established IR plan.
A) Incorrect — Shutting the network down immediately is not appropriate for early triage; it could cause collateral damage and is not aligned with standard IR procedures for containment, which prioritize escalation based on severity.
C) Incorrect — While using an attack framework is important, the option states “determine what the incident response will consist of” before proper triage and incident classification; sequencing is critical.
D) Incorrect — Notifying law enforcement is premature; internal containment and IR coordination should occur first unless a legal or regulatory trigger is met.



A security team conducts a lessons-learned meeting after struggling to determine who should conduct the next steps following a security event. Which of the following should the team create to address this issue?

  1. Service-level agreement
  2. Change management plan
  3. Incident response plan
  4. Memorandum of understanding

Answer(s): C

Explanation:

Option C is correct because an incident response plan defines roles, responsibilities, and procedures for handling security events, clarifying who conducts next steps during an incident. A) Service-level agreement governs inter-organizational service expectations, not incident execution ownership. B) Change management plan focuses on documenting changes to systems and processes, not incident sequencing. D) Memorandum of understanding is a formal agreement between parties; it does not establish internal incident ownership or stepwise procedures. INSUFFICIENT_KNOWLEDGE



A cybersecurity analyst notices unusual network scanning activity coming from a country that the company best mitigation technique?
does not do business with. Which of the following is the

  1. Geoblock the offending source country.
  2. Block the IP range of the scans at the network firewall.
  3. Perform a historical trend analysis and look for similar scanning activity.
  4. Block the specific IP address of the scans at the network firewall.

Answer(s): A

Explanation:

Option A is correct because geoblocking the offending source country directly mitigates unsolicited scans from that region, aligning with an immediate, perimeter-based defense step when the country is not a business partner.
A) Correct — Geoblock the offending source country to stop traffic from that region at the edge, reducing noise and potential threats without needing to enumerate individual IPs.
B) Incorrect — Blocking an IP range may be too broad or dynamic if scanning originates from multiple ranges; not as targeted as geoblocking a whole country.
C) Incorrect — Historical trend analysis is passive; it does not stop current scans or reduce exposure.
D) Incorrect — Blocking a single IP may miss related sources; a country-wide block is more effective for pervasive scans.



An analyst has received an IPS event notification from the SIEM stating an IP address, which is known to be malicious, has attempted to exploit a zero-day vulnerability on several web servers. The exploit contained the following snippet:

/wp-json/trx_addons/V2/get/sc_layout?sc=wp_insert_user&role=administrator

Which of the following controls would work best to mitigate the attack represented by this snippet?

  1. Limit user creation to administrators only.
  2. Limit layout creation to administrators only.
  3. Set the directory trx_addons to read only for all users.
  4. Set the directory V2 to read only for all users.

Answer(s): A

Explanation:

Option A is correct because restricting user creation to administrators prevents an attacker from elevating privileges via the exposed WP REST endpoint sc_layout?sc=wp_insert_user&role=administrator, blocking the targeted abuse of user provisioning during the exploit.
B is incorrect because limiting layout creation does not address user provisioning or privilege escalation via the vulnerable endpoint.
C is incorrect because making trx_addons read-only may mitigate some modification risks but does not prevent creation of new administrator accounts through the exploit path.
D is incorrect because making V2 read-only blocks read access, not the write-capability exploited by wp_insert_user; the attack leverages user creation functionality, not mere read access.



A penetration tester submitted data to a form in a web application, which enabled the penetration tester to retrieve user credentials. Which of the following should be recommended for remediation of this application vulnerability?

  1. Implementing multifactor authentication on the server OS
  2. Hashing user passwords on the web application
  3. Performing input validation before allowing submission
  4. Segmenting the network between the users and the web server

Answer(s): C

Explanation:

Option C is correct because input validation before submission mitigates injection and other parameter tampering vulnerabilities that allow retrieval of credentials exposed through improper handling of user input. Incorrect — A: Multifactor authentication on the server OS does not address insecure input handling or credential exposure caused by form submission. Incorrect — B: Hashing passwords on the web app addresses at-rest storage, not the vulnerability that allows credential access via the form submission. Incorrect — D: Network segmentation does not fix insecure input processing or credential leakage from the application layer.



A cybersecurity team lead is developing metrics to present in the weekly executive briefs. Executives are interested in knowing how long it takes to stop the spread of malware that enters the network. Which of the following metrics should the team lead include in the briefs?

  1. Mean time between failures
  2. Mean time to detect
  3. Mean time to remediate
  4. Mean time to contain

Answer(s): C

Explanation:

Option C is correct because Mean Time to Remediate measures the duration from detection to full remediation, aligning with stopping malware spread. A) Mean time between failures relates to reliability of hardware/software failures, not incident containment. B) Mean time to detect focuses on how quickly threats are identified, not how fast containment/remediation occurs. D) Mean time to contain measures time to limit spread after detection, but remediation encompasses complete removal and restoration, which directly ties to stopping spread. Hence, C best communicates the full remediation duration.

Question 62:

  • Correct answer: D (per the page)

  • Note: The explanation text on the page describes option B (use ZDX score and Analyze Score to trigger the Y Engine analysis), indicating a mismatch between the stated answer and the rationale.

  • Key concept: For fast root-cause analysis, leverage telemetry and auto-correlated insights:
- Use the user’s ZDX score for AWS and run Analyze Score to activate the Y Engine, which correlates metrics across network, client, and application to pinpoint the issue quickly.
  • Why the other options are less effective:
- A: Only checks for outages; doesn’t provide actionable root-cause analysis. - C: Deep Trace helps visibility but is manual and time-consuming. - D: Packet capture is invasive and slow; not the quickest path to root cause.

Question 32:

  • Answer: A (2.4GHz)

  • Why: Lower-frequency signals have longer wavelengths and experience less attenuation when passing through walls and obstacles. Higher frequencies (5GHz, 6GHz) are more easily blocked by walls. NFC operates over very short distances and is not meant to penetrate walls. So 2.4 GHz best penetrates physical objects like walls.

Question 3:

  • False is the correct answer (Option B).

Why:
  • In Snowflake, a database is a metadata object that exists within a single Snowflake account. Accounts are isolated—there isn’t one database that lives in multiple accounts.
  • You can access data across accounts via data sharing or database replication, but these create separate database objects in the other accounts (e.g., a database in the consumer account created from a share), not a single shared database across accounts.

So a single database cannot exist in more than one Snowflake account.

Question 1:

  • Correct answer: Edate = sys.argv[1]
  • Why this is correct:
- When a Databricks Job passes parameters to a notebook, those parameters are supplied to the notebook's Python process as command-line arguments. The first argument after the script name is sys.argv[1], so date = sys.argv[1] captures the passed date value directly.
  • How it compares to other options:
- date = spark.conf.get("date") reads from Spark config, not from job parameters. - input() waits for user input at runtime, which isn’t how job parameters are provided. - date = dbutils.notebooks.getParam("date") would work if the notebook were invoked via dbutils.notebook.run with parameters, not

Question 528:

  • Correct answer: NSG flow logs for NSG1 (Option B)

  • Why:
- Traffic Analytics uses NSG flow logs to analyze traffic patterns. You must have NSG flow logs enabled for the NSGs you want to monitor. - An Azure Log Analytics workspace is also required to store and query the traffic data. - Network Watcher must be available in the subscription for traffic analytics to function.
  • What to configure (brief steps):
- Ensure Network Watcher is enabled in the East US region (for the subscription/region). - Enable NSG flow logs on NSG1. - Ensure a Log Analytics workspace exists and is accessible (read/write) so Traffic Analytics can store and query logs.
  • Why other options aren’t correct:
- “Diagnostic settings for VM1” or “Diagnostic settings for NSG1” alone don’t guarantee flow logs are captured and sent to Log Analytics, which Traffic Analytics relies on. - “Insights for VM1” is not how Traffic Analytics collects traffic data.

Question 23:
The correct answer is Domain admin (option B), not Fabric admin.

  • Domain admin provides domain-level management: create domains/subdomains and assign workspaces within those domains, which matches the tasks while following least privilege.
  • Fabric admin is global-level access and is more privileges than needed for this scenario (it would grant broader control across the Fabric environment).

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:

  • A) 10.10.10.0/28 ? 10.10.10.0–10.10.10.15
  • B) 10.10.13.0/25 ? 10.10.13.0–10.10.13.127
  • C) 10.10.13.144/28 ? 10.10.13.144–10.10.13.159
  • D) 10.10.13.208/29 ? 10.10.13.208–10.10.13.215

The destination Host A’s IP must fall within 10.10.13.208–10.10.13.215 for the /29 to be the best match. Since /29 is the longest prefix among the matching options, Router1 will use 10.10.13.208/29.
Thus, the correct answer is D.

Question 3:

  • Correct answer: Phase 4, Post Accreditation

  • Explanation:
- In DITSCAP, the four phases are: - Phase 1: Definition (concept and requirements) - Phase 2: Verification (design and testing) - Phase 3: Validation (fielding and evaluation) - Phase 4: Post Accreditation (ongoing operations and lifecycle management) - The description—continuing operation of an accredited IT system and addressing changing threats throughout its life cycle—fits the Post Accreditation phase, which covers operations, maintenance, monitoring, and reauthorization as threats and environment evolve.

Question 129:
Correct answer: CNAME

  • A CNAME record creates an alias for a domain, so newapplication.comptia.org will resolve to whatever IP address www.comptia.org resolves to. This ensures both names point to the same resource without duplicating the IP.
  • Why not the others:
- SOA defines authoritative information for a zone. - MX specifies mail exchange servers. - NS designates name servers for a zone.
  • Notes: The alias name (newapplication.comptia.org) should not have other records if you use a CNAME for it, and CNAMEs aren’t used for the zone apex (root) domain. This scenario uses a subdomain, so a CNAME is appropriate.

Question 1:

  • Correct answer: C

  • Why this is best:
- Uses OS Login with IAM, so SSH access is granted via Google accounts rather than distributing per-user SSH keys. - Granting the compute.osAdminLogin role to a Google group gives admin access to all team members in a centralized, auditable way. - Access is auditable: Cloud Audit Logs show who accessed which VM, satisfying the security requirement to determine who accessed a given instance.
  • How it works:
- Enable OS Login on the project/instances (enable-oslogin metadata). - Add the team’s

Question 2:

  • Answer: D. Azure Advisor

  • Why: To view security-related recommendations for resources in the Compute and Apps area (including App Service Web Apps and Functions), you use Azure Advisor. Advisor surfaces personalized best-practice recommendations across resources, including security, and shows which resources are affected and the severity.

  • Why not the others:
- Azure Log Analytics is for ad-hoc querying of telemetry, not for viewing security recommendations. - Azure Event Hubs is for streaming telemetry data, not for security recommendations.
  • Quick tip: In the portal, navigate to Azure Advisor and check the Security recommendations for App Services to see actionable items and affe
