Correct : C

An access point (AP) provides users with an extended footprint that allows connections from multiple devices within a designated Wireless Local Area Network (WLAN).

Router: Typically used to connect different networks, not specifically for extending wireless coverage.

Switch: Used to connect devices within a wired network, not for providing wireless access.

Access Point (AP): Extends wireless network coverage, allowing multiple wireless devices to connect to the network.

Firewall: Primarily used for network security, controlling incoming and outgoing traffic based on security rules, not for providing wireless connectivity.

Correct : D

Security Assertion Markup Language (SAML) is an XML-based standard used for exchanging authentication and authorization data between parties, particularly between an identity provider (IdP) and a service provider (SP). SAML is commonly used in Single Sign-On (SSO) solutions to pass sensitive user information, such as login credentials and attributes, securely between the identity provider and the service provider.

SAML (Security Assertion Markup Language): Facilitates web-based authentication and authorization, allowing users to access multiple services with a single set of credentials.

XML-based: Uses XML to encode the authentication and authorization data, ensuring secure transmission of user information.

Identity Federation: Enables secure sharing of identity information across different security domains, making it ideal for enterprise SSO solutions.

Network Reference:

CompTIA Network+ N10-007 Official Certification Guide: Covers authentication protocols, including SAML.

Correct : C

An SVI (Switched Virtual Interface) is a logical interface on a Layer 3-capable switch used to route traffic between VLANs. This is particularly useful in environments where voice and data traffic need to be separated, as each type of traffic can be assigned to different VLANs and routed accordingly.

SVI (Switched Virtual Interface): A virtual interface created on a switch for inter-VLAN routing.

VLAN Routing: Enables the routing of traffic between VLANs on a Layer 3 switch, allowing for logical separation of different types of traffic, such as voice and data.

Use Case: Commonly used in scenarios where efficient and segmented traffic management is required, such as in VoIP implementations.

Network Reference:

CompTIA Network+ N10-007 Official Certification Guide: Discusses VLANs, SVIs, and their applications in network segmentation and routing.

Cisco Networking Academy: Provides training on VLAN configuration and inter-VLAN routing using SVIs.

Network+ Certification All-in-One Exam Guide: Covers network segmentation techniques, including the use of SVIs for VLAN routing.

Correct : B

Jumbo frames are Ethernet frames with a payload greater than the standard maximum transmission unit (MTU) of 1500 bytes. Configuring jumbo frames can reduce overhead and increase efficiency in storage networks by allowing more data to be sent in each frame, thus reducing the number of frames needed to transmit the same amount of data.

Reduced Overhead: By sending larger frames, the relative overhead for headers and acknowledgments is reduced.

Increased Efficiency: Larger frames mean fewer packets to process, leading to better utilization of network bandwidth and improved performance in high-throughput environments like storage networks.

Configuration: Requires support from all devices in the network path, including switches and network interface cards (NICs).

Network Reference:

CompTIA Network+ N10-007 Official Certification Guide: Explains jumbo frames and their benefits in reducing network overhead.

Cisco Networking Academy: Provides training on network optimization techniques, including the use of jumbo frames.

Network+ Certification All-in-One Exam Guide: Covers advanced Ethernet features, including jumbo frames and their configuration for improved network performance.

Correct : D

802.1x is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. This ensures that only authorized devices can access the network, making it ideal for mitigating the risk of unknown devices connecting to the network, especially in accessible areas.

802.1x Authentication: Requires devices to authenticate using credentials (e.g., username and password, certificates) before gaining network access.

Access Control: Prevents unauthorized devices from connecting to the network, enhancing security in public or semi-public areas.

Implementation: Typically used in conjunction with a RADIUS server to manage authentication requests.

Network Reference:

CompTIA Network+ N10-007 Official Certification Guide: Covers 802.1x and its role in network security.

Cisco Networking Academy: Provides training on implementing 802.1x for secure network access control.
