Cisco Certified Support Technician (CCST) NetworkingExam (CCST-Networking日本語版) - CCST-Networking日本語 Exam Practice Test
セキュリティ オプションを左側のリストから右側の特性に移動します。各セキュリティ オプションは、1 回、複数回、またはまったく使用しないこともできます。
注意: 正解ごとに部分的な得点が与えられます。
注意: 正解ごとに部分的な得点が与えられます。
Correct Answer:
Explanation:
The correct matching of the security options to their characteristics is as follows:
* WPA2-Enterprise: Uses a RADIUS server for authentication
* WEP: Uses a minimum of 40 bits for encryption
* WPA2-Personal: Uses AES and a pre-shared key for authentication
Here's why each security option matches the characteristic:
* WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.
* WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.
* WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network.
These security options are essential for protecting wireless networks from unauthorized access and ensuring data privacy.

Correct Answer:
Explanation:
Here's how each protocol aligns with the correct TCP/IP model layer:
* TCP (Transmission Control Protocol): This protocol belongs to theTransportlayer, which is responsible for providing communication between applications on different hosts1.
* IP (Internet Protocol): IP is part of theInternetworklayer, which is tasked with routing packets across network boundaries to their destination1.
* FTP (File Transfer Protocol): FTP operates at theApplicationlayer, which supports application and end- user processes.It is used for transferring files over the network1.
* Ethernet: While not a protocol within the TCP/IP stack, Ethernet is associated with theNetwork Interfacelayer, which corresponds to the link layer of the TCP/IP model and is responsible for the physical transmission of data1.
The TCP/IP model layers are designed to work collaboratively to transmit data from one layer to another, with each layer having specific protocols that perform functions necessary for the data transmission process1.
* TCP:
* TCP Model Layer: Transport
* Explanation: The Transport layer is responsible for end-to-end communication and error handling. TCP (Transmission Control Protocol) operates at this layer to provide reliable, ordered, and error-checked delivery of data.
* IP:
* TCP Model Layer: Internetwork
* Explanation: The Internetwork layer, also known as the Internet layer, is responsible for logical addressing and routing. IP (Internet Protocol) operates at this layer to route packets across networks.
* FTP:
* TCP Model Layer: Application
* Explanation: The Application layer provides network services to applications. FTP (File Transfer Protocol) operates at this layer to transfer files between computers over a network.
* Ethernet:
* TCP Model Layer: Network
* Explanation: The Network layer, also known as the Link layer in the TCP/IP model, is responsible for physical addressing and access to thephysical medium. Ethernet operates at this layer to provide the physical and data link functions.
* Transport Layer: This layer is responsible for providing communication services directly to the application processes running on different hosts. TCP is a core protocol in this layer.
* Internetwork Layer: This layer is responsible for logical addressing, routing, and packet forwarding.
IP is the primary protocol for this layer.
* Application Layer: This layer interfaces directly with application processes and provides common network services. FTP is an example of a protocol operating in this layer.
* Network Layer: In the TCP/IP model, this layer includes both the data link and physical layers of the OSI model. Ethernet is a protocol used in this layer to define network standards and communication protocols at the data link and physical levels.
