Question#1

A person is troubleshooting a network issue and needs to see details about network adapters and their settings.
Which Windows command should be used?

A. ipconfig

B. traceroute

C. nslookup

D. netstat

Explanation:
Theipconfigcommand 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.
nslookupis used for querying DNS records.
netstatprovides details about active network connections and listening ports, but not adapter configurations.

Question#2

A computer network has software that tracks successful and unsuccessful connection attempts to the network in order to better identify attacks.
Which network security concept does this scenario address?

A. Accounting

B. Authentication

C. Availability

D. Authorization

Explanation:
Accounting(also known asauditing or logging) is a network security concept that tracks user activities, includingsuccessful and failed authentication attempts, system changes, and resource access. This helps in detecting and mitigating security breaches.
Authenticationverifies user identity but does not track activity.
Availabilityensures systems remain operational.
Authorizationcontrols user permissions but does not log activities.

Question#3

An organization's network has been the target of several cyberattacks.
Which strategy should the organization use for Wi-Fi hardening?

A. Trust local hosts by default

B. Disable ESSID broadcasting

C. Add more access points

D. Implement wired equivalent privacy (WEP)

Explanation:
Disabling ESSID broadcastingprevents the Wi-Fi network name from being publicly visible,making it harder for attackers to discover and target the network. While this is not a foolproof security measure, it adds an additional layer of protection against unauthorized access.
Trusting local hosts by defaultis risky and not a security best practice.
Adding more access pointsimproves coverage but does not enhance security.
WEPis outdated and highly vulnerable to attacks; WPA2 or WPA3 should be used instead.

Question#4

1.Which scenario demonstrates a violation of the integrity component of the CIA triad?

A. A network's domain name system server has not been fully operational for one month.

B. An employee accidentally modified a customer account incorrectly.

C. A company has an unacceptably high network downtime during high-traffic time periods.

D. A company stores sensitive customer data without access controls.

Explanation:
A violation ofintegrityoccurs whendata is modified incorrectly, whether intentionally or by accident. In this case, anemployee modifying a customer account incorrectlydemonstrates a breach of data integrity.
A and Crelate toavailability, as they describe system downtime.
Drelates toconfidentiality, as it describes improper data protection.

Question#5

An attacker uses a network device to take over an existing connection between two network computers.
Which malicious attack strategy is represented in the scenario?

A. Dictionary attack

B. Social engineering

C. Session hijacking

D. IP address spoofing

Explanation:
Session hijackingoccurs when an attacker takes over an established connection between two devices, often by stealing session tokens or manipulating network traffic. This allows the attacker to impersonate a legitimate user and gain unauthorized access.
Dictionary attackinvolves password guessing, not hijacking active connections.
Social engineeringtricks users into providing information but does not hijack sessions.
IP address spoofingdisguises the attacker's identity but does not necessarily take over a session.
