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.
Answer:
Explanation:
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-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WEP (Wired Equivalent Privacy) is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.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.

Which command will display all the current operational settings configured on a Cisco router?
- A. show version
- B. show protocols
- C. show running-config
- D. show startup-config
Answer: C
Explanation:
The show running-config command is used on a Cisco router to display the current operational settings that are actively configured in the router's RAM. This command outputs all the configurations that are currently being executed by the router, which includes interface configurations, routing protocols, access lists, and other settings. Unlike show startup-config, which shows the saved configuration that the router will use on the next reboot, show running-config reflects the live, current configuration in use.
Reference: = The information is supported by multiple sources that detail the use of Cisco commands, particularly the show running-config command as the standard for viewing the active configuration on a Cisco device123.
show running-config: This command displays the current configuration running on the router. It includes all the operational settings and configurations applied to the router.
show protocols: This command shows the status of configured protocols on the router but not the entire configuration.
show startup-config: This command displays the configuration saved in NVRAM, which is used to initialize the router on startup, but not necessarily the current running configuration.
show version: This command provides information about the router's software version, hardware components, and uptime but does not display the running configuration.

Which two statements are true about the IPv4 address of the default gateway configured on a host? (Choose 2.) Note: You will receive partial credit for each correct selection.
- A. The IPv4 address of the default gateway must be the first host address in the subnet.
- B. The default gateway is the IPv4 address of the router interface connected to the same local network as the host.
- C. Hosts learn the default gateway IPv4 address through router advertisement messages.
- D. The same default gateway IPv4 address is configured on each host on the local network.
- E. The default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host.
Answer: B,D
Explanation:
*Statement B: "The same default gateway IPv4 address is configured on each host on the local network." This is true because all hosts on the same local network (subnet) use the same default gateway IP address to send packets destined for other networks.
*Statement D: "The default gateway is the IPv4 address of the router interface connected to the same local network as the host." This is true because the default gateway is the IP address of the router's interface that is directly connected to the local network.
*Statement A: "The IPv4 address of the default gateway must be the first host address in the subnet." This is not necessarily true. The default gateway can be any address within the subnet range.
*Statement C: "The default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host." This is not true; the default gateway is the IP address of the router's physical or logical interface connected to the local network.
*Statement E: "Hosts learn the default gateway IPv4 address through router advertisement messages." This is generally true for IPv6 with Router Advertisement (RA) messages, but not typically how IPv4 hosts learn the default gateway address.

NEW QUESTION # 27
Which protocol allows you to securely upload files to another computer on the internet?
- A. NTP
- B. SFTP
- C. HTTP
- D. ICMP
Answer: B
Explanation:
SFTP, or Secure File Transfer Protocol, is a protocol that allows for secure file transfer capabilities between networked hosts. It is a secure extension of the File Transfer Protocol (FTP). SFTP encrypts both commands and data, preventing passwords and sensitive information from being transmitted openly over the network. It is typically used for secure file transfers over the internet and is built on the Secure Shell (SSH) protocol1.
Reference: =
* What Is SFTP? (Secure File Transfer Protocol)
* How to Use SFTP to Safely Transfer Files: A Step-by-Step Guide
* Secure File Transfers: Best Practices, Protocols And Tools
The Secure File Transfer Protocol (SFTP) is a secure version of the File Transfer Protocol (FTP) that uses SSH (Secure Shell) to encrypt all commands and data. This ensures that sensitive information, such as usernames, passwords, and files being transferred, are securely transmitted over the network.
* ICMP (Internet Control Message Protocol) is used for network diagnostics and is not designed for file transfer.
* NTP (Network Time Protocol) is used to synchronize clocks between computer systems and is not related to file transfer.
* HTTP (HyperText Transfer Protocol) is used for transmitting web pages over the internet and does not inherently provide secure file transfer capabilities.
Thus, the correct protocol that allows secure uploading of files to another computer on the internet is SFTP.

You plan to use a network firewall to protect computers at a small office. For each statement about firewalls, select True or False.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
A firewall can direct all web traffic to a specific IP address.
True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
A firewall can block traffic to specific ports on internal computers.
True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
A firewall can prevent specific apps from running on a computer.
False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application
management.
