Free WGU Network-and-Security-Foundation Real Questions (page: 4)

Network-and-Security-Foundation PDF — 62 Questions

A person is troubleshooting a network issue and needs to see a list of all active network connections.

Which Linux command should be used?

  1. nslookup
  2. netstat
  3. dig
  4. ifconfig

Answer(s): B

Explanation:

The netstat command in Linux displays active network connections, listening ports, and network statistics. It is useful for diagnosing network issues and identifying open connections.

nslookup is for DNS queries.

dig provides DNS information, not network connection status.

ifconfig shows network interface details but does not list active connections.



Users of a network have been experiencing issues. In the course of troubleshooting, an administrator wants to test DNS resolution against a host.

Which command in Linux should be used for this purpose?

  1. traceroute
  2. netstat
  3. dig
  4. ifconfig

Answer(s): C

Explanation:

The dig command in Linux is used for DNS troubleshooting. It queries DNS records and provides detailed information about domain name resolutions.

traceroute tracks the path packets take to a destination but does not diagnose DNS.

netstat lists active connections, not DNS records.

ifconfig is used for managing network interfaces.



Which layer of the TCP/IP model includes the Internet Protocol (IP)?

  1. Physical or network access
  2. Application
  3. Network or internet
  4. Transport

Answer(s): C

Explanation:

The Network or Internet layer of the TCP/IP model is responsible for addressing, routing, and delivering packets across networks. The Internet Protocol (IP) operates at this layer, ensuring that data is correctly routed from the source to the destination.

Physical or network access layer deals with hardware transmission (e.g., Ethernet, Wi-Fi).

Application layer includes end-user services (e.g., HTTP, FTP).

Transport layer manages data flow using protocols like TCP and UDP but does not handle IP addressing.



What is the TCP/IP layer that includes the User Datagram Protocol (UDP)?

  1. Application
  2. Network or internet
  3. Physical or network access
  4. Transport

Answer(s): D

Explanation:

The Transport layer in the TCP/IP model includes the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). UDP is a connectionless protocol used for fast, lightweight data transmission where reliability is not the priority (e.g., video streaming, VoIP).

Application layer handles end-user services but not transport mechanisms.

Network or internet layer deals with IP addressing and routing, not UDP.

Physical or network access layer concerns hardware transmission methods.



What is the layer of the OSI model that creates, maintains, and disconnects process communications over the network?

  1. Data link
  2. Physical
  3. Session
  4. Transport

Answer(s): C

Explanation:

The Session layer (Layer 5 of the OSI model) is responsible for establishing, maintaining, and terminating communication sessions between network applications. It ensures that data exchanges remain synchronized and structured.

Data link layer handles error detection and frame transmission.

Physical layer deals with hardware-level transmission.

Transport layer ensures reliable data delivery but does not manage sessions.



Which layer of the OSI model includes the ICMP?

  1. Transport
  2. Session
  3. Network
  4. Application

Answer(s): C

Explanation:

The Network layer (Layer 3 of the OSI model) includes the Internet Control Message Protocol (ICMP), which is used for network diagnostics (e.g., ping command). ICMP helps in error reporting and network troubleshooting.

Transport layer handles reliable data delivery (e.g., TCP, UDP).

Session layer manages communication sessions.

Application layer provides end-user services.



Which layer of the OSI model includes the TCP?

  1. Application
  2. Transport
  3. Session
  4. Network

Answer(s): B

Explanation:

The Transport layer (Layer 4 of the OSI model) includes the Transmission Control Protocol (TCP), which provides reliable, connection-oriented communication. TCP ensures error-checking, sequencing, and retransmission of lost packets.

Application layer deals with end-user protocols like HTTP and FTP.

Session layer manages communication sessions but not transport protocols.

Network layer focuses on IP addressing and routing, not transport mechanisms.



Which layer of the OSI model includes HTTP?

  1. Application
  2. Network
  3. Session
  4. Transport

Answer(s): A

Explanation:

The Application layer (Layer 7 of the OSI model) includes Hypertext Transfer Protocol (HTTP), which is used for web communication. This layer provides network services directly to applications and users.

Network layer deals with IP addressing and packet routing.

Session layer manages connections but does not include HTTP.

Transport layer ensures reliable data transmission but does not handle application protocols.

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: E — date = 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

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.
