Important WGU Network and Security Foundation Exam Questions

Answer: D

Explanation:

A Wireless Local Area Network (WLAN) enables wireless connectivity within a defined geographic area, such as a library, office, or coffee shop. WLANs use Wi-Fi technology to allow users to access the internet without physical cables.

Storage Area Networks (SANs) are used for data storage and do not provide internet connectivity to users.

Metropolitan Area Networks (MANs) cover larger areas, such as cities, and are not used within a single building.

Personal Area Networks (PANs) connect personal devices like smartphones and laptops over short distances, such as via Bluetooth, but do not support public internet access.

Answer: D

Explanation:

Integrity in the CIA (Confidentiality, Integrity, Availability) triad ensures that data is not altered in an unauthorized manner. In networking, integrity mechanisms such as checksums, message authentication codes (MACs), and digital signatures verify that transmitted data has not been tampered with. If an IP packet has an invalid checksum, the system detects corruption and requests retransmission, ensuring data integrity.

Confidentiality protects against unauthorized access but does not ensure data consistency.

Availability ensures that resources are accessible but does not verify data correctness.

Consistency is not a formal component of the CIA triad.

Answer: C

Explanation:

This scenario describes a data export attack, where an attacker steals sensitive information (e.g., personal data, trade secrets, or financial records) and transfers it to another entity, often for malicious purposes.

Launch point refers to using a compromised system for further attacks.

Denial of availability disrupts access to resources.

Data modification involves unauthorized changes rather than theft.

Answer: C

Explanation:

Infrastructure as a Service (IaaS) provides virtualized computing resources, including virtual machines, storage, and networking, while allowing users full control over operating systems and applications. Examples include AWS EC2 and Google Compute Engine.

SaaS provides ready-to-use applications (e.g., Google Docs).

FaaS runs code in response to events (e.g., AWS Lambda).

PaaS provides development environments but not full infrastructure control.

Answer: D

Explanation:

A launch point attack occurs when an attacker compromises a system and uses it as a foothold to spread malware, conduct reconnaissance, or launch further attacks against other systems. Botnets and command-and-control (C2) servers operate this way.

Denial of availability disrupts service, but does not spread attacks.

Data export steals data instead of launching further attacks.

Data modification changes existing information but does not involve propagating threats.
