Question 1

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

Which Linux command should be used?



Answer : B

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.


Question 2

An attacker uses a poisoned domain name on the domain name server to navigate users to the attacker's site.

Which malicious attack strategy is represented in the scenario?



Answer : A

Pharming is an attack that manipulates the Domain Name System (DNS) to redirect users to fraudulent websites without their knowledge. Attackers poison DNS records or compromise routers to reroute traffic to malicious sites designed to steal information.

Brute-force attack involves password guessing, not domain manipulation.

IP address spoofing disguises a device's identity but does not alter DNS records.

Session hijacking takes over active user sessions but does not redirect websites.


Question 3

A library has a network that allows patrons to use their mobile devices to connect to the internet.

Which type of network is described?



Answer : D

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.


Question 4

A person is troubleshooting a network issue and needs to see details about network adapters and their settings.

Which Windows command should be used?



Answer : A

The ipconfig command in Windows provides details about a computer's network adapters, including IP addresses, subnet masks, default gateways, and DNS settings. It is particularly useful for troubleshooting connectivity issues.

traceroute (or tracert in Windows) is used to trace the path packets take to a destination.

nslookup is used for querying DNS records.

netstat provides details about active network connections and listening ports, but not adapter configurations.


Question 5

In order to reduce the risk of insider attacks, a company assigns role-based permissions to its users.

Which network security concept does this scenario address?



Answer : D

Authorization is the process of granting specific access rights and permissions based on user roles. By implementing Role-Based Access Control (RBAC), organizations ensure that users only have access to resources necessary for their job functions, reducing the risk of insider threats.

Authentication verifies identity but does not control access.

Accounting logs activities but does not restrict access.

Availability ensures system uptime but is unrelated to permissions.


Question 6

A company wants to use a cloud service to obtain virtual machines with pre-installed and configured software.

Which cloud service model should be used?



Answer : C

Platform as a Service (PaaS) provides a pre-configured computing environment that includes an operating system, runtime, and development tools, making it ideal for developers who want a ready-to-use platform. Examples include Google App Engine and Microsoft Azure App Services.

SaaS provides fully hosted applications, not just pre-configured virtual machines.

IaaS provides infrastructure without pre-installed software.

FaaS executes specific functions without persistent infrastructure.


Question 7

Which layer of the OSI model includes the TCP?



Answer : B

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.
