DRAG DROP
Move the security options from the list on the left to its characteristic on the right. You may use each security option once, more than once, or not at all.
Note: You will receive partial credit for each correct answer.
Solution:
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-Enterprise uses 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✑ WEP (Wired Equivalent Privacy) is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today??s standards.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:A
A support technician examines the front panel of a Cisco switch and sees 4 Ethernet cables connected in the first four ports. Ports 1, 2, and 3 have a green
LED. Port 4 has a blinking green light. What is the state of the Port 4?
Correct Answer:C
On a Cisco switch, a port with a blinking green LED typically indicates that the port is up (active) and is currently transmitting or receiving data. This is a normal state indicating active traffic on the port.
•A. Link is up with cable malfunctions: Usually indicated by an amber or blinking amber light.
•B. Link is up and not stable: Not typically indicated by a green blinking light.
•D. Link is up and there is no activity: Would be indicated by a solid green light without blinking.
Thus, the correct answer is C. Link is up and active. References :=

What is the purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch?
Correct Answer:D
The primary purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch is to facilitate remote management of the switch. By configuring an IP address on the management VLAN, network administrators can access the switch??s Command Line Interface (CLI) remotely using protocols such as Telnet or Secure Shell (SSH). This allows for convenient configuration changes, monitoring, and troubleshooting without needing physical access to the switch1.

•Cisco - VLAN Configuration Guide
•Remote Management of Switches
Assigning an IP address to the management VLAN interface (often the VLAN 1 interface by default) on a Layer 2 switch allows network administrators to remotely manage the switch using protocols such as Telnet or SSH. This IP address does not affect the switch's ability to route traffic between VLANs but provides a means to access and configure the switch through its Command Line Interface (CLI).
•A: The switch does not act as a default gateway; this is typically a function of a Layer 3 device like a router.
•B: The switch does not resolve URLs; this is typically a function of DNS servers.
•C: The switch can relay DHCP requests but does not typically provide DHCP services itself; this is usually done by a dedicated DHCP server or router.
Thus, the correct answer is D. To enable access to the CLI on the switch through Telnet or SSH.

A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network. The output of the command is shown as follows:
What can you tell from the command output?
Correct Answer:C
The tracert command output shows the path taken to reach the destination IP address, 192.168.1.10. The command output indicates:
•Hops 1 and 2 are successfully reached.
•Hop 3 times out, meaning the router at hop 3 did not respond to the tracert request. However, this does not necessarily indicate a problem with forwarding packets, as some routers may be configured to block or not respond to ICMP requests.
•Hops 4 and 5 are successfully reached, with hop 5 being the destination IP 192.168.1.10, indicating that the server is reachable.
Thus, the correct answer is C. The server with the address 192.168.1.10 is reachable over the network.

•Understanding Traceroute
The tracert command output indicates that the server with the address 192.168.1.10 is reachable over the network. The asterisk (*) at hop 3 suggests that the probe sent to that hop did not return a response, which could be due to a variety of reasons such as a firewall blocking ICMP packets or the router at that hop being configured not to respond to ICMP requests. However, since the subsequent hops (4 and 5) are showing response times, it means that the packets are indeed getting through and the server is reachable12. References :=

HOTSPOT
You want to list the IPv4 addresses associated with the host name www.companypro.net.
Solution:
To list the IPv4 addresses associated with the host name www.companypro.net, you should use the following command:
nslookup www.companypro.net
This command will query the DNS servers to find the IP address associated with the hostname provided. If you want to ensure that it returns the IPv4 address, you can specify the -type=A option, which stands for Address records that hold IPv4 addresses1. However, the nslookup command by default should return the IPv4 address if available.
To list the IPv4 addresses associated with the host name www.companypro.net, you should use the nslookup command.
✑ Command: nslookup
✑ Target: www.companypro.net So, the completed command is:
✑ nslookup www.companypro.net
✑ nslookup: This command is used to query the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record.
✑ www.companypro.net: This is the domain name you want to query to obtain its
associated IP addresses. References:
