CCNA sample questions set 26

In this article, I describe some CCNA sample questions for practice before appearing in the CCNA 200-301 exam. The following questions are basic questions and related to the CCNA sample questions set 26. There are multiple sample questions set on this website for prior practice online. All questions are described with relevant answers. You can take the following questions and answer as reference for CCNA 200-301 exam. You may also need to do more practice with other websites and books to practice the CCNA sample questions set 26. 

Question 1. What is a VLAN hop?

The term “VLAN hop” refers to an exploit in which an attacker tries to gain unauthorized access to network resources that are intended to be protected by VLANs (Virtual Local Area Networks). This attack is also known as a VLAN hopping attack or VLAN jumping attack.

In a VLAN hopping attack, an attacker sends forged frames to a switch in an attempt to manipulate the VLAN tagging. The goal is to fool the switch into forwarding frames to the attacker that should have been isolated on a separate VLAN. This can allow the attacker to gain access to sensitive network resources or to intercept traffic that they should not be able to see.

To prevent VLAN hopping attacks, network administrators can use techniques such as VLAN access control lists (VACLs) and port security to control access to VLANs. Additionally, it is important to disable unnecessary VLANs and to configure trunk ports carefully to prevent unauthorized access to VLANs. This is the answer to question 1 of CCNA sample questions set 26.

Question 2. What is a VLAN voice?

VLAN voice is a feature of Voice over IP (VoIP) telephony systems that separates voice traffic from data traffic on a network. It involves creating a separate Virtual LAN (VLAN) for voice traffic to ensure that it is given priority over other types of traffic, such as web browsing or file transfers. By segregating voice traffic onto its own VLAN, the voice traffic can be prioritized to ensure that there is no loss of quality or reliability due to competing traffic on the network. This can help to improve call quality and reduce latency, which is particularly important in a business environment where communication is critical. This is the answer to question 2 of CCNA sample questions set 26.

Question 3. What is a VLAN data?

In networking, a VLAN (Virtual Local Area Network) can be used to logically segment a physical network into multiple broadcast domains. The VLAN data refers to the network traffic, such as user data, email, file transfers, and other general network traffic that is assigned to a specific VLAN. By separating different types of network traffic into different VLANs, network administrators can better manage and prioritize the flow of data on their network. For example, a VLAN data can be created for different departments in an organization, such as finance, marketing, and human resources, allowing each department to communicate with each other, while preventing other departments from accessing their data. This is the answer to question 3 of CCNA sample questions set 26.

Question 4. What is a VLAN management?

In computer networking, VLAN management refers to the configuration and administration of Virtual Local Area Networks (VLANs). VLANs are used to logically group devices on a network, even if they are not physically connected to the same switch or network segment. 

VLAN management involves the creation and configuration of VLANs, including defining VLAN IDs, assigning ports to VLANs, and configuring VLAN-specific settings such as VLAN tagging and VLAN pruning. It also includes tasks such as monitoring VLAN traffic, troubleshooting VLAN connectivity issues, and ensuring network security by enforcing VLAN segmentation. 

Effective VLAN management is important for organizations that need to segregate network traffic for security or performance reasons, such as separating guest Wi-Fi traffic from internal corporate traffic, isolating high-bandwidth applications, or preventing unauthorized access to sensitive data. This is the answer to question 4 of CCNA sample questions set 26.

Question 5. What is a VLAN security?

VLAN security refers to the measures taken to secure a VLAN or group of VLANs from unauthorized access and attacks. Since VLANs are logical groupings of devices within a network, it is important to ensure that only authorized devices can access the resources on a particular VLAN. VLAN security can include a range of measures such as port security, access control lists, VLAN access control, and VLAN segmentation. These measures help to prevent unauthorized access, data breaches, and other security threats, and ensure that data is transmitted only to intended recipients. VLAN security is an important aspect of network security, particularly in larger enterprise networks where there may be a large number of VLANs and devices. This is the answer to question 5 of CCNA sample questions set 26.
