NEW QUESTION # 462
Which of the following best explains the role of confidentiality with regard to data at rest?
Answer: A
Explanation:
* Confidentiality with Data at Rest: Confidentiality is a core principle of data security, ensuring that data stored (at rest) is only accessible to authorized individuals. This protection is achieved through mechanisms such as encryption, access controls, and permissions.
* Privileged Access: The statement "Data can be accessed after privileged access is granted" aligns with the confidentiality principle, as it restricts data access to users who have been granted specific permissions or roles. Only those with the appropriate credentials or permissions can access the data.
* Incorrect Options:
* A. "Data can be accessed by anyone on the administrative network." This violates the principle of confidentiality by allowing unrestricted access.
* B. "Data can be accessed remotely with proper training." This focuses on remote access rather than restricting access based on privileges.
* D. "Data can be accessed after verifying the hash." This option relates more to data integrity rather than confidentiality.

NEW QUESTION # 463
Which of the following attacks involves an attacker tricking a network switch into believing the attacker’s host is another switch, allowing access to traffic from multiple VLANs?
Answer: C
Explanation:
VLAN hopping occurs when an attacker tricks a switch into believing the host is another switch by generating tagged frames or exploiting trunk negotiation (DTP). This allows the attacker to access traffic from multiple VLANs, potentially stealing sensitive data.
* B. Evil twin is a rogue wireless AP attack, unrelated to switch impersonation.
* C. DNS poisoning corrupts name resolution, not VLAN access.
* D. ARP spoofing is a Layer 2 on-path attack, not masquerading as a switch.

NEW QUESTION # 464
A network administrator wants users to be able to authenticate to the corporate network using a port-based authentication framework when accessing both wired and wireless devices. Which of the following is the best security feature to accomplish this task?
Answer: D
Explanation:
802.1X is a port-based network access control (PNAC) protocol that provides an authentication mechanism to devices wishing to connect to a LAN or WLAN. It is widely used for secure network access, ensuring that only authenticated devices can access the network, whether they are connecting via wired or wireless means.
802.1X works in conjunction with an authentication server, such as RADIUS, to validate the credentials of devices trying to connect.References: CompTIA Network+ study materials.
NEW QUESTION # 465
A university is implementing a new campus wireless network. A network administrator needs to configure the network to support a large number of devices and high-bandwidth demands from students.
Which of the following wireless technologies should the administrator consider for this scenario?
Answer: D
Explanation:
Wi-Fi 6E is the best choice for high-density environments, such as a university campus. It:
Supports more devices with OFDMA (Orthogonal Frequency-Division Multiple Access) Uses the 6GHz band, reducing congestion Provides faster speeds and lower latency This makes Wi-Fi 6E ideal for large networks with high-bandwidth demands, like those in a university setting.
Breakdown of Options:
A . Bluetooth - Used for short-range, low-power connections, not large-scale wireless networks.
B . Wi-Fi 6E - ✅ Correct answer. Designed for high-density environments, improving speed and efficiency.
C . 5G - Used for mobile networks, but not ideal for campus-wide local wireless infrastructure.
D . LTE - Used for cellular data, not for campus-wide Wi-Fi.

NEW QUESTION # 466
A network technician implements a switch with multiple VLANs. Which of the following items should the technician configure to ensure that clients can communicate with clients in other VLANs?
Answer: B
Explanation:
To enable communication between VLANs, the technician must configure inter-VLAN routing. On a Layer
3 switch, this is commonly done by creating an SVI (Switched Virtual Interface) for each VLAN. An SVI provides a virtual Layer 3 interface with an IP address that acts as the default gateway for hosts in that VLAN. Once SVIs exist and routing is enabled, the switch can route traffic between VLAN subnets internally, allowing clients in different VLANs to communicate (subject to any security controls). This aligns with Network+ (N10-009) infrastructure objectives covering VLANs, Layer 2/Layer 3 switching, and the requirement for routing to cross broadcast domains.
ACLs can permit or deny inter-VLAN traffic, but they do not create the routing function by themselves.
VXLAN is an overlay tunneling technology used mainly in data centers to extend Layer 2 networks over Layer 3 fabrics, not the standard solution for basic VLAN-to-VLAN connectivity on a switch. VPC is not the required configuration element for inter-VLAN routing in this context. Therefore, configuring SVIs is the correct and most direct answer.
