NEW QUESTION # 391
A technician needs to identify a computer on the network that is reportedly downloading unauthorized content. Which of the following should the technician use?

Answer: A

Explanation:
Packet Capture: This method captures and inspects network traffic to identify unauthorized downloads or malicious behavior. It provides detailed insight into the data being transmitted, making it the best tool for this scenario.
Anomaly alerts (A): Alerts may indicate unusual activity but do not provide detailed traffic analysis.
Port mirroring (B): Port mirroring can redirect traffic for analysis but requires a packet capture tool for deeper inspection.
Performance monitoring (C): Focuses on system performance metrics, not detailed traffic content.
Reference: CompTIA Network+ Official Study Guide, Domain 4.3 (Network Monitoring Tools).


NEW QUESTION # 392
A network administrator is implementing security zones for each department. Which of the following should the administrator use to accomplish this task?

Answer: C

Explanation:
* Understanding ACLs:
* Access Control Lists (ACLs): A set of rules used to control network traffic and restrict access to network resources by filtering packets based on IP addresses, protocols, or ports.
* Implementing Security Zones:
* Defining Zones: ACLs can be used to create security zones by applying specific rules to different departments, ensuring that only authorized traffic is allowed between these zones.
* Control Traffic: ACLs control inbound and outbound traffic at network boundaries, enforcing security policies and preventing unauthorized access.
* Comparison with Other Options:
* Port Security: Limits the number of devices that can connect to a switch port, preventing MAC address flooding attacks, but not used for defining security zones.
* Content Filtering: Blocks or allows access to specific content based on predefined policies, typically used for web filtering rather than network segmentation.
* NAC (Network Access Control): Controls access to the network based on the security posture of devices but does not define security zones.
* Implementation Steps:
* Define ACL rules based on the requirements of each department.
* Apply these rules to the appropriate network interfaces or firewall policies to segment the network into security zones.


NEW QUESTION # 393
Which of the following attacks utilizes a network packet that contains multiple network tags?

Answer: D

Explanation:
VLAN hopping is an attack where an attacker crafts packets with multiple VLAN tags, allowing them to traverse VLAN boundaries improperly. This can result in gaining unauthorized access to network segments that are supposed to be isolated. The other options do not involve the use of multiple network tags. MAC flooding aims to overwhelm a switch's MAC address table, DNS spoofing involves forging DNS responses, and ARP poisoning involves sending fake ARP messages.


NEW QUESTION # 394
Which of the following is a modular device that provides the interface between fiber-optic or copper cabling and networking equipment?

Answer: A

Explanation:
An SFP (Small Form-factor Pluggable) transceiver is a modular device that provides the interface between fiber-optic or copper cabling and the networking equipment (e.g., switch or router). It operates primarily at Layer 2 (Data Link), converting optical or electrical signals into frames usable by the network device.
* A. SC is a fiber connector type, not the transceiver.
* B. DAC (Direct Attach Copper) is a passive copper cable assembly with fixed transceivers, not a general-purpose module.
* D. Twinaxial cable is a copper medium, not an interface device.
References (CompTIA Network+ N10-009):
* Domain: Networking Concepts - Transceivers (SFP, GBIC, QSFP), fiber connectivity, OSI model mapping.
