- A. The routers at hops 5 and 6 are offline.
- B. The trace successfully reached the www.cisco.com server.
- C. The IPv6 address associated with the www.cisco.com server is 2600:1408: c400: 38d: : b33.
- D. The trace failed after the fourth hop.
- E. The device sending the trace has IPv6 address 2600:1408:c400:38d :: b33.
Answer: B,C
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 # 27
Move each protocol from the list on the left to the correct TCP/IP model layer on the right.
Note: You will receive partial credit for each correct match.
Answer:
Explanation:
Explanation:
Here's how each protocol aligns with the correct TCP/IP model layer:
* TCP (Transmission Control Protocol): This protocol belongs to theTransportlayer, which is responsible for providing communication between applications on different hosts1.
* IP (Internet Protocol): IP is part of theInternetworklayer, which is tasked with routing packets across network boundaries to their destination1.
* FTP (File Transfer Protocol): FTP operates at theApplicationlayer, which supports application and end-user processes.It is used for transferring files over the network1.
* Ethernet: While not a protocol within the TCP/IP stack, Ethernet is associated with theNetwork Interfacelayer, which corresponds to the link layer of the TCP/IP model and is responsible for the physical transmission of data1.
The TCP/IP model layers are designed to work collaboratively to transmit data from one layer to another, with each layer having specific protocols that perform functions necessary for the data transmission process1.
* TCP:
* TCP Model Layer: Transport
* Explanation: The Transport layer is responsible for end-to-end communication and error handling. TCP (Transmission Control Protocol) operates at this layer to provide reliable, ordered, and error-checked delivery of data.
* IP:
* TCP Model Layer: Internetwork
* Explanation: The Internetwork layer, also known as the Internet layer, is responsible for logical addressing and routing. IP (Internet Protocol) operates at this layer to route packets across networks.
* FTP:
* TCP Model Layer: Application
* Explanation: The Application layer provides network services to applications. FTP (File Transfer Protocol) operates at this layer to transfer files between computers over a network.
* Ethernet:
* TCP Model Layer: Network
* Explanation: The Network layer, also known as the Link layer in the TCP/IP model, is responsible for physical addressing and access to the physical medium. Ethernet operates at this layer to provide the physical and data link functions.
* Transport Layer: This layer is responsible for providing communication services directly to the application processes running on different hosts. TCP is a core protocol in this layer.
* Internetwork Layer: This layer is responsible for logical addressing, routing, and packet forwarding.
IP is the primary protocol for this layer.
* Application Layer: This layer interfaces directly with application processes and provides common network services. FTP is an example of a protocol operating in this layer.
* Network Layer: In the TCP/IP model, this layer includes both the data link and physical layers of the OSI model. Ethernet is a protocol used in this layer to define network standards and communication protocols at the data link and physical levels.

NEW QUESTION # 28
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 # 29
Which component of the AAA service security model provides identity verification?
- A. Accounting
- B. Authorization
- C. Auditing
- D. Authentication
Answer: D
Explanation:
The AAA service security model consists of three components: Authentication, Authorization, and Accounting.
*Authentication: This is the process of verifying the identity of a user or device. It ensures that only legitimate users can access the network or service.
*Authorization: This determines what an authenticated user is allowed to do or access within the network.
*Auditing/Accounting: This component tracks the actions of the user, including what resources they access and what changes they make.
Thus, the correct answer is C. Authentication.

NEW QUESTION # 30
A user initiates a trouble ticket stating that an external web page is not loading. You determine that other resources both internal and external are still reachable.
Which command can you use to help locate where the issue is in the network path to the external web page?
- A. nslookup
- B. ipconfig/all
- C. tracert
- D. ping -t
Answer: C
Explanation:
The tracert command is used to determine the route taken by packets across an IP network. When a user reports that an external web page is not loading, while other resources are accessible, it suggests there might be an issue at a certain point in the network path to the specific web page. The tracert command helps to diagnose where the breakdown occurs by displaying a list of routers that the packets pass through on their way to the destination. It can identify the network segment where the packets stop progressing, which is valuable for pinpointing where the connectivity issue lies. References := Cisco CCST Networking Certification FAQs - CISCONET Training Solutions, Command Prompt (CMD): 10 network-related commands you should know, Network Troubleshooting Commands Guide: Windows, Mac & Linux - Comparitech, How to Use the Traceroute and Ping Commands to Troubleshoot Network, Network Troubleshooting Techniques: Ping, Traceroute, PathPing.
*tracert Command: This command is used to determine the path packets take to reach a destination. It lists all the hops (routers) along the way and can help identify where the delay or failure occurs.
*ping -t: This command sends continuous ping requests and is useful for determining if a host is reachable but does not provide path information.
*ipconfig /all: This command displays all current TCP/IP network configuration values and can be used to verify network settings but not to trace a network path.
*nslookup: This command queries the DNS to obtain domain name or IP address mapping, useful for DNS issues but not for tracing network paths.

NEW QUESTION # 32
An engineer configured a new VLAN named VLAN2 for the Data Center team. When the teamtries to ping addresses outside VLAN2 from a computer in VLAN2, they are unable to reach them.
What should the engineer configure?
- A. Static route
- B. Additional VLAN
- C. Default gateway
- D. Default route
Answer: C
Explanation:
When devices within a VLAN are unable to reach addresses outside their VLAN, it typically indicates that they do not have a configured path to external networks. The engineer should configure a default gateway for VLAN2. The default gateway is the IP address of the router's interface that is connected to the VLAN, which will route traffic from the VLAN to other networks12.

*VLAN 2 not able to ping gateway - Cisco Community
*VLANs: Virtual Local Area Networks (VLANs) logically segment network traffic to improve security and performance. Devices within the same VLAN can communicate directly.
*Default Gateway: For devices in VLAN2 to communicate with devices outside their VLAN, they need a default gateway configured. The default gateway is typically a router or Layer 3 switch that routes traffic between different VLANs and subnets.
*Additional VLAN: Not needed in this scenario as the issue is related to routing traffic outside VLAN2, not creating another VLAN.
*Default Route: While a default route on the router may be necessary, the primary issue for devices within VLAN2 is to have a configured default gateway.
*Static Route: This is used on routers to manually specify routes to specific networks but does not address the need for a default gateway on the client devices.

When prioritizing trouble tickets, the most critical issues affecting business operations or high-impact activities should be addressed first. Here's a breakdown of the tickets:
* Ticket 1: Relocation of a printer, while necessary, is not urgent and does not impact critical operations.
* Ticket 2: An ongoing webinar losing internet access is critical, especially if the webinar is time-sensitive and involves multiple participants.
* Ticket 3: Slower response time for a cloud-based application is important but typically not as urgent as a complete loss of internet access for a live event.
* Ticket 4: Wireless access down in the cafeteria affects users but does not have the same immediate impact as a live webinar losing connectivity.
Thus, the correct answer is B. Ticket 2: An online webinar is taking place in the conference room. The video conferencing equipment lost internet access.

NEW QUESTION # 34
During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?
- A. Transport
- B. Data Link
- C. Network
- D. Session
Answer: B
Explanation:
OSI model
During the data encapsulation process, theData Link layerof the OSI model is responsible for adding a header that contains MAC addressing information and a trailer used for error checking.The header typically includes the source and destination MAC addresses, while the trailer contains a Frame Check Sequence (FCS) which is used for error detection1.
The Data Link layer ensures that messages are delivered to the proper device on a LAN using hardware addresses and translates messages from the Network layer into bits for the Physical layer to transmit. It also controls how data is placed onto the medium and is received from the medium through the physical hardware.

NEW QUESTION # 35
Which protocol allows you to securely upload files to another computer on the internet?
- A. SFTP
- B. ICMP
- C. HTTP
- D. NTP
Answer: A
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.

NEW QUESTION # 36
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 default gateway is the Loopback0 interface IPv4 address of the router connected to the same local network as the host.
- B. The same default gateway IPv4 address is configured on each host on the local network.
- C. The IPv4 address of the default gateway must be the first host address in the subnet.
- D. Hosts learn the default gateway IPv4 address through router advertisement messages.
- E. The default gateway is the IPv4 address of the router interface connected to the same local network as the host.
Answer: B,E
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.
