NEW QUESTION # 19
Which wireless security option uses a pre-shared key to authenticate clients?
- A. 802.1x
- B. WPA2-Enterprise
- C. WPA2-Personal
- D. 802.1q
Answer: C
Explanation:
WPA2-Personal, also known as WPA2-PSK (Pre-Shared Key), is the wireless security option that uses a pre-shared key to authenticate clients. This method is designed for home and small office networks and doesn't require an authentication server. Instead, every user on the network uses the same key or passphrase to connect1.

NEW QUESTION # 21
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-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* WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today's standards.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.
NEW QUESTION # 22
A host is given the IP address 172.16.100.25 and the subnet mask 255.255.252.0.
What is the CIDR notation for this address?

NEW QUESTION # 30
What is the purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch?
- A. To enable the switch to resolve URLs for the attached the devices
- B. To enable the switch to act as a default gateway for the attached devices
- C. To enable the switch to provide DHCP services to other switches in the network
- D. To enable access to the CLI on the switch through Telnet or SSH
Answer: D
Explanation:
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.
References :=
*Understanding the Management VLAN
*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.

Which two conclusions can you make from the output of the tracert command? (Choose 2.) Note: You will receive partial credit for each correct answer.
- A. The routers at hops 5 and 6 are offline.
- B. The trace failed after the fourth hop.
- C. The IPv6 address associated with the www.cisco.com server is 2600:1408: c400: 38d: : b33.
- D. The device sending the trace has IPv6 address 2600:1408:c400:38d :: b33.
- E. The trace successfully reached the www.cisco.com server.
Answer: C,E
Explanation:
*Statement A: "The trace successfully reached the www.cisco.com server." This is true as indicated by the
"Trace complete" message at the end, showing that the trace has reached its destination.
*Statement C: "The IPv6 address associated with the www.cisco.com server is 2600:1408:c400:38d::b33." This is true because the final hop in the trace, which is the destination, has this IPv6 address.
*Statement B: "The trace failed after the fourth hop." This is incorrect as the trace continues beyond the fourth hop, despite some intermediate timeouts.
*Statement D: "The routers at hops 5 and 6 are offline." This is not necessarily true. The routers might be configured to not respond to traceroute requests.
*Statement E: "The device sending the trace has IPv6 address 2600:1408:c400:38d::b33." This is incorrect; this address belongs to the destination server, not the sender.

NEW QUESTION # 32
An app on a user's computer is having problems downloading data. The app uses the following URL to download data:
https://www.companypro.net:7100/api
You need to use Wireshark to capture packets sent to and received from that URL.
Which Wireshark filter options would you use to filter the results? Complete the command by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
To capture packets sent to and received from the URLhttps://www.companypro.net:7100/apiusing Wireshark, you would use the following filter options:
* Protocol:tcp
* Filter Type:port
* Port Number:7100
This filter setup in Wireshark will display all TCP packets that are sent to or received from port 7100, which is the port specified in the URL for the API service. Since HTTPS typically uses TCP as the transport layer protocol, filtering by TCP and the specific port number will help isolate the relevant packets for troubleshooting the app's data download issues.
* cp: The app is using HTTPS, which relies on the TCP protocol for communication.
* port: The specific port number used by the application, which in this case is 7100.
* 7100: This is the port specified in the URL (https://www.companypro.net:7100/api).
This filter will capture all TCP traffic on port 7100, allowing you to analyze the packets related to the application's data download.

NEW QUESTION # 33
Which protocol allows you to securely upload files to another computer on the internet?
- A. HTTP
- B. ICMP
- C. SFTP
- D. NTP
Answer: C
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.
References :=
*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.
