A company is sending a switch to a remote site to be reused. An administrator needs to move the switch and ensure no network settings persist. Which of the following databases does the administrator need to delete?

Correct Answer:A
The VLAN database is the database that stores the VLAN configuration information on a switch, such as the VLAN IDs, names, and ports. The VLAN database is stored in a separate file from the switch configuration file, and it is not affected by the erase startup- config or reload commands. Therefore, to delete the VLAN database, the administrator needs to use a specific command, such as delete flash:vlan.dat or delete vlan.dat, depending on the switch model. Deleting the VLAN database will ensure that no network settings related to VLANs persist on the switch when it is moved to a remote site. References

A network technician is troubleshooting a new web server connectivity issue. The network technician discovers the following on the support ticket
• The server's IP address can be pinged from the client PCs,
• Access to the web resource works correctly when on the server's console.
• No clients can access the servers data via URL.
• The server does not have a firewall configured
• No ACLs are preventing connectivity from the client's network.
• All services on the server are operating normally, which was confirmed by the server team.
Which of the following actions will resolve the issue?

Correct Answer:C
The problem is likely related to DNS resolution, as the clients are able to ping the server's IP address but not access the web resource via URL. The other answers do not address this issue. Configuring A records for the web server will ensure that clients are able to access the web resource via its domain name.

A company is designing a new complex. The primary and alternate data centers will be in separate buildings 6.2mi (10km) apart and will be connected via fiber.
Which of the following types of SFP is the best choice?

Correct Answer:C
10GBASE-LR is the best choice for connecting two data centers that are 6.2 miles (10 km) apart via fiber, because it supports a maximum distance of 6.2 miles (10 km) over single- mode fiber. 10GBASE-SR and 1000BASE-SX are designed for short-range connections over multi-mode fiber, and they can only reach up to 1,312 feet (400 m) and 1,804 feet (550 m), respectively. 10000BASE-LX is a typo and does not exist as a standard.

A network administrator determines that even when optimal wireless coverage is configured, the network users still report constant disconnections After troubleshooting, the administrator determines that moving from one location to another causes the disconnection Which of the following settings should provide better network stability?

Correct Answer:B
In this case, the most likely cause of the constant disconnections when moving from one location to another is likely due to a problem with the roaming functionality of the wireless network. The setting that would likely provide better network stability in this situation is the RSSI roaming threshold, which determines the signal strength required for a client device to remain connected to the wireless network. If the roaming threshold is set too low, the client device may disconnect and reconnect to the network too frequently as it moves between different access points. On the other hand, if the threshold is set too high, the client device may not roam to a new access point when necessary, leading to a loss of connectivity. Adjusting the RSSI roaming threshold to an appropriate value may help to improve the stability of the wireless network in this situation.

Users ate moving back into an office that had been vacant for awhile. Ten workstations are hooked up in the office, but one workstation cannot obtain a link with (he switch. A network engineer checks the documentation and cable labeling, and everything is hooked up as expected. The engineer moves the connection lo a different switchport. but a link still cannot be obtained. When the engineer puts a tone generator on (he infrastructure cable, no tone is heard at the far end. Which of the following issues is the engineer MOST likely trying to find?

Correct Answer:B
A break in the cable means that there is no electrical continuity between the two ends of the cable, which prevents the signal from reaching the switch. A tone generator is a device that sends an audible signal through the cable, and if no tone is heard at the far end, it indicates a break in the cable.
