• Question 41:

  Given the following information:

  

  Which of the following command-line tools would generate this output?

  A. netstat
  B. arp
  C. dig
  D. tracert
  A. netstat

  ---

  Explanation/Reference:

  -

  The "netstat" command displays network connections, routing tables, and network interface statistics.

  -

  The "dig" (Domain Information Groper) command is used for querying the Domain Name System (DNS) to obtain domain name or IP address mapping. -The "arp" (Address Resolution Protocol) command is used to view and manage the ARP cache, which contains mapping information between IP addresses and their corresponding physical (MAC) addresses on a network.

  -

  The "tracert" (or traceroute) command is used to determine the path that packets take from the source device to the destination device on an IP network

• Question 42:

  Which of the following OSI model layers would allow a user to access and download flies from a remote computer?

  A. Session
  B. Presentation
  C. Network
  D. Application
  D. Application

  ---

  Explanation/Reference:

  The application layer of the OSI model (Open Systems Interconnection) is responsible for providing services to applications that allow users to access and download files from a remote computer. These services include file transfer, email, and web access, as well as other related services. In order for a user to access and download files from a remote computer, the application layer must provide the necessary services that allow the user to interact with the remote computer.

• Question 43:

  An administrator is working with the local ISP to troubleshoot an issue. Which of the following should the ISP use to define the furthest point on the network that the administrator is responsible for troubleshooting?

  A. Firewall
  B. A CSU/DSU
  C. Demarcation point
  D. Router E. Patch panel
  C. Demarcation point

  ---

  Explanation/Reference:

  Demarc point denotes the separation of responsibility from ISP to administrator.

• Question 44:

  A network technician is attempting to harden a commercial switch that was recently purchased. Which of the following hardening techniques best mitigates the use of publicly available information?

  A. Changing the default password
  B. Blocking inbound SSH connections
  C. Removing the gateway from the network configuration
  D. Restricting physical access to the switch
  A. Changing the default password

  ---

  Explanation/Reference:

  Changing the default password is a hardening technique that best mitigates the use of publicly available information, such as vendor documentation, online forums, or hacking tools, that may reveal the default credentials of a commercial switch. By changing the default password to a strong and unique one, the network technician can prevent unauthorized access to the switch configuration and management.

• Question 45:

  SIMULATION

  A network technician was recently onboarded to a company. A manager has

  tasked the technician with documenting the network and has provided the technician With partial information from previous documentation.

  Instructions:

  Click on each switch to perform a network discovery by entering commands into the terminal. Fill in the missing information using drop-down menus provided.

  

  

  

  A. See thefor detailed information on this simulation. (Note: Ips will be change on each simulation task, so we have given example answer for the understanding)
  B. PlaceHolder
  C. PlaceHolder
  D. PlaceHolder
  A. See thefor detailed information on this simulation. (Note: Ips will be change on each simulation task, so we have given example answer for the understanding)

  ---

  To perform a network discovery by entering commands into the terminal, you can use the following steps:

  Click on each switch to open its terminal window.

  Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.

  Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.

  Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch. Fill in the missing information in the diagram using the drop-down menus provided. Here is an example of how to fill in the missing information for Core Switch 1. The IP address of Core Switch 1 is 192.168.1.1. The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2. 192.168.2.0/24, VLAN 3: 192.168.3.0/24.

  The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2. The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2. The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4. You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.

• Question 46:

  Which of the following protocol types describes secure communication on port 443?

  A. ICMP
  B. UDP
  C. TCP
  D. IP
  C. TCP

  ---

  Explanation/Reference:

  TCP is the protocol type that describes secure communication on port 443. TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable and ordered delivery of data packets over an IP network. TCP uses port numbers to identify different applications or services on a device. Port 443 is the default port for HTTPS (Hypertext Transfer Protocol Secure), which is an extension of HTTP that uses SSL (Secure Sockets Layer) or TLS (Transport Layer Security) encryption to protect data in transit between a web server and a web browser.

• Question 47:

  A network technician needs to install security updates on several switches on me company's network. The management team wants this completed as quickly and efficiently as possible. Which of the following should the technician do to perform the updates?

  A. Upload the security update onto each switch using a terminal emulator and a console cable.
  B. Configure a TFTP server. SSH into each device, and perform the update.
  C. Replace each old switch with new switches that have the updates already performed.
  D. Connect a USB memory stick to each switch and perform the update.
  B. Configure a TFTP server. SSH into each device, and perform the update.

  ---

  Explanation/Reference:

  TFTP Server: Setting up a TFTP (Trivial File Transfer Protocol) server allows you to store the security update files in one location. This avoids the need to transfer files individually to each switch.

  SSH: Secure Shell (SSH) is a secure protocol used for remote access and management of network devices. SSH provides encryption and secure authentication, making it the preferred method for accessing devices remotely.

• Question 48:

  A cafeteria is lacing lawsuits related to criminal internet access that was made over its guest network. The marketing team, however, insists on keeping the cafeteria phone number as the wireless passphrase. Which of the following actions would Improve wireless security while accommodating the marketing team and accepting the terms of use?

  A. Setting WLAN security to use EAP-TLS
  B. Deploying a captive portal tor user authentication
  C. Using geofencing to limit the area covered by the WLAN
  D. Configuring guest network isolation
  B. Deploying a captive portal tor user authentication

  ---

  Explanation/Reference:

  A captive portal is a web page that is presented to a user before they are allowed to access a network. It is used to authenticate users and to ensure that all users have accepted the terms of use for the network. By deploying a captive portal, the cafeteria can require users to enter their phone number as the passphrase, while still providing an additional layer of security.

• Question 49:

  When a user makes a VoIP phone call and finishes speaking, the user experiences a delay in hearing a response. Which of the following should the network engineer check?

  A. Jitter
  B. Latency
  C. Bandwidth
  D. CRC errors
  B. Latency

• Question 50:

  Which of the following is an advanced distance vector routing protocol that automates routing tables and also uses some features of link-state routing protocols?

  A. OSPF
  B. RIP
  C. EIGRP
  D. BGP
  C. EIGRP

  ---

  Explanation/Reference:

  EIGRP is an advanced distance vector routing protocol that is able to automatically update routing tables and also uses features of link-state routing protocols, such as the ability to send updates about the current topology of the network. EIGRP also has the ability to use a variety of algorithms to determine the best route for a packet to take, allowing for more efficient routing across the network.
