NEW QUESTION # 213
A network technician needs to ensure that all files on a company's network can be moved in a safe and protected manner without interception from someone who is not the intended recipient. Which of the following would allow the network technician to meet these requirements?
- A. SMTP
- B. SFTP
- C. FTP
- D. TFTP
Answer: B
Explanation:
SFTP stands for Secure File Transfer Protocol, which is a network protocol that allows secure and encrypted file transfer over SSH (Secure Shell) connections. SFTP can prevent unauthorized interception or modification of files during transmission, as well as provide authentication and authorization mechanisms for both the client and the server.
FTP, TFTP, and SMTP are not secure protocols, as they do not encrypt the data or the credentials during file transfer. FTP (File Transfer Protocol) and TFTP (Trivial File Transfer Protocol) are used for transferring files between hosts, while SMTP (Simple Mail Transfer Protocol) is used for sending and receiving email messages. These protocols can be easily intercepted, tampered, or spoofed by attackers, compromising the confidentiality, integrity, and availability of the files and the network. Reference:

Dirty or contaminated fiber patch cord connectors can cause signal loss and poor network performance, and may even prevent a link from being established. Before trying any other troubleshooting steps, it is important to ensure that the fiber patch cord connectors are clean and free of debris.
NEW QUESTION # 215
A company wants to add a local redundant data center to its network in case of failure at its primary location. Which of the following would give the LEAST amount of redundancy for the company's network?
- A. Cloud site
- B. Cold site
- C. Hot site
- D. Warm site
Answer: B
Explanation:
The question asks about the least amount of redundancy for a company's network that wants to add a local backup data center.
The answer is not B, because a hot site is a fully operational data center that can take over the primary site's functions immediately in case of a disaster. It has the most amount of redundancy, as it replicates the primary site's data, applications, and hardware.
The answer is not C, because a cloud site is a data center that is hosted by a third-party provider on the internet. It can provide a high level of redundancy, as it can scale up or down according to the demand and availability of resources. It also offers flexibility and cost-efficiency for the company.
The answer is not D, because a warm site is a partially operational data center that can take over the primary site's functions within a short time in case of a disaster. It has a moderate amount of redundancy, as it has some of the primary site's data, applications, and hardware, but not all of them.
The answer is A, because a cold site is a data center that is not operational and requires a lot of time and effort to set up and activate in case of a disaster. It has the least amount of redundancy, as it has none of the primary site's data, applications, or hardware. It only has the basic infrastructure, such as power, cooling, and network connectivity.

NEW QUESTION # 216
Which of the following describes traffic going in and out of a data center from the internet?
- A. Spine and leaf
- B. North-South
- C. Fibre Channel
- D. Demarcation point
Answer: B
Explanation:
Network traffic is the amount of data moving across a computer network at any given time. Network traffic is broken down into data packets and sent over a network before being reassembled by the receiving device or computer1.
Network traffic has two directional flows, north-south and east-west. North-south traffic refers to client-to-server traffic that moves between the data center and the rest of the network (i.e., a location outside of the data center). East-west traffic refers to traffic within a data center, also known as server-to-server traffic12.
A data center is a facility that houses computing and networking equipment, such as servers, switches, routers, firewalls, and storage devices. Data centers provide centralized processing, storage, and access to data and applications for organizations and users3.
Data centers need to handle both north-south and east-west traffic efficiently and securely. North-south traffic is typically generated by users or customers who access data or applications hosted in the data center from the internet or other networks. East-west traffic is typically generated by applications or services that communicate with each other within the data center.
The question asks which of the following describes traffic going in and out of a data center from the internet. The correct answer is B. North-South, because this is the type of traffic that flows between the data center and the external network. The other options are incorrect for the following reasons:
A . Demarcation point is the physical point where the responsibility for the network changes from one party to another, such as from a service provider to a customer. It does not describe network traffic.
C . Fibre Channel is a high-speed network technology that connects servers and storage devices in a data center. It does not describe network traffic, but rather a network protocol.
D . Spine and leaf is a network topology that consists of two layers of switches: spine switches that interconnect with leaf switches, and leaf switches that connect to servers and devices. It does not describe network traffic, but rather a network design. Reference:

You can use the same steps to fill in the remediation form for other components.
To enter commands in each device, you can use the following steps:
Click on the device to open its terminal window.
Enter the command ipconfig /all to display the IP configuration of the device, including its IP address, subnet mask, default gateway, and DNS servers.
Enter the command ping <IP address> to test the connectivity and reachability to another device on the network by sending and receiving echo packets. Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
Enter the command tracert <IP address> to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets with increasing TTL values.
Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch
1.
Here is an example of how to enter commands in PC1:
Click on PC1 to open its terminal window.
Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1.
Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets.
Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.
You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.

A network administrator is preparing new switches that will be deployed to support a network extension project. The lead network engineer has already provided documentation to ensure the switches are set up properly Which of the following did the engineer most likely provide?
- A. Physical network diagram
- B. Site survey reports
- C. Logical network diagram
- D. Baseline configurations
Answer: D
Explanation:
Baseline configurations are the standard settings and parameters that are applied to network devices, such as switches, routers, firewalls, etc., to ensure consistent performance, security, and functionality across the network. Baseline configurations can include aspects such as IP addresses, VLANs, passwords, protocols, access lists, firmware versions, etc. Baseline configurations are usually documented and updated regularly to reflect any changes or modifications made to the network devices.
The lead network engineer most likely provided baseline configurations to the network administrator to ensure that the new switches are set up properly and in accordance with the network design and policies. Baseline configurations can help to simplify the deployment process, reduce errors and inconsistencies, and facilitate troubleshooting and maintenance.
The other options are not correct because they are not the most likely documentation that the lead network engineer provided to the network administrator. They are:
Physical network diagram. A physical network diagram is a graphical representation of the physical layout and connections of the network devices and components, such as cables, ports, switches, routers, servers, etc. A physical network diagram can help to visualize the network topology, identify the locations and distances of the devices, and plan for cabling and power requirements. However, a physical network diagram does not provide the specific settings and parameters that need to be configured on the network devices, such as the switches.
Site survey reports. A site survey report is a document that summarizes the findings and recommendations of a site survey, which is a process of assessing the suitability and readiness of a location for installing and operating network devices and components. A site survey report can include aspects such as environmental conditions, power and cooling availability, security and safety measures, interference and noise sources, signal coverage and quality, etc. A site survey report can help to identify and resolve any potential issues or challenges that may affect the network performance and reliability. However, a site survey report does not provide the specific settings and parameters that need to be configured on the network devices, such as the switches.
Logical network diagram. A logical network diagram is a graphical representation of the logical structure and functionality of the network devices and components, such as subnets, IP addresses, VLANs, protocols, routing, firewall rules, etc. A logical network diagram can help to understand the network design, architecture, and policies, as well as the data flow and communication paths between the devices. However, a logical network diagram does not provide the specific settings and parameters that need to be configured on the network devices, such as the switches.

NEW QUESTION # 230
Which of the following is the most accurate NTP time source that is capable of being accessed across a network connection?
- A. Stratum 7 device
- B. Stratum 0 device
- C. Stratum 16 device
- D. Stratum 1 device
Answer: D
Explanation:
NTP (Network Time Protocol) is a protocol that synchronizes the clocks of network devices with a reference time source. NTP uses a hierarchical system of time sources, called strata, to distribute the time information. A stratum 0 device is the most accurate time source, such as an atomic clock or a GPS receiver, but it is not directly accessible across a network connection. A stratum 1 device is a network device that is directly connected to a stratum 0 device, such as a dedicated NTP server or a router with a GPS antenna, and it acts as a primary time server for other network devices. A stratum 2 device is a network device that synchronizes its time with a stratum 1 device, and so on. The higher the stratum number, the lower the accuracy and reliability of the time source. A stratum 16 device is a network device that has no valid time source and is considered unsynchronized.
Reference:
Part 1 of current page talks about how Bing is your AI-powered copilot for the web and provides various examples of how it can help you with different tasks, such as writing a joke, creating a table, or summarizing research. However, it does not mention anything about NTP or time sources.
Part 2 of current page shows the search results for "ai powered search bing chat", which include web, image, and news results. However, none of these results seem to be relevant to the question, as they are mostly about Bing's features, products, or announcements, not about NTP or time sources.
Therefore, I cannot find the answer or the explanation from the current page. I have to use my own knowledge and information from other sources to verify the answer and provide a short but comprehensive explanation. I will cite these sources using numerical references.
