  Out-of-band management

  When a Cisco switch is not accessible from the network, the recommended out-of-band method to access its running configuration is through theconsole port. Out-of-band management involves accessing the network device through a

  dedicated management channel that is not part of the data network.The console port provides direct access to the switch's Command Line Interface (CLI) without using the network, which is essential when the switch cannot be accessed

  remotely via the network12.

  You want to store files that will be accessible by every user on your network.

  Which endpoint device do you need?

  A. Access point
  B. Server
  C. Hub
  D. Switch
  B. Server

  ---

  Explanation/Reference:

  To store files that will be accessible by every user on a network, you would need aserver. A server is a computer system that provides data to other computers. It can serve data to systems on a local network (LAN) or a wide network (WAN)

  over the internet.In this context, a file server would be set up to store and manage files, allowing users on the network to access them from their own devices1.

  References:

  What is a Server?

  Understanding Servers and Their Functions

  A server is a computer designed to process requests and deliver data to other computers over a local network or the internet. In this case, to store files that will be accessible by every user on the network, a file server is the appropriate

  endpoint device. It provides a centralized location for storing and managing files, allowing users to access and share files easily. A. Access point: Provides wireless connectivity to a network. C. Hub: A basic networking device that connects

  multiple Ethernet devices together, making them act as a single network segment. D. Switch: A networking device that connects devices on a computer network by using packet switching to forward data to the destination device.

  Thus, the correct answer is B. Server.

• Question 24:

  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. Additional VLAN
  B. Default route
  C. Default gateway
  D. Static route
  C. Default gateway

  ---

  Explanation/Reference:

  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.

  References := -Understanding and Configuring VLAN Routing and Bridging on a Router Using the IRB Feature -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.

  ---

  Explanation/Reference:

  The two interfaces are administratively shut down:

  The two interfaces have default IP addresses assigned:

  The two interfaces can communicate over Layer 2:

  Interface Status: The absence of the "shutdown" command means the interfaces are not administratively shut down.

  IP Address Assignment: There is no evidence in the output that IP addresses have been assigned to the interfaces, which would typically be shown as "ip address" entries.

  Layer 2 Communication: Switch interfaces in their default state operate at Layer 2, enabling them to forward Ethernet frames and participate in Layer 2 communication.

• Question 26:

  HOTSPOT

  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.

  Hot Area:

  

  

  ---

  Explanation/Reference:

  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.

  Explanation/Reference:

  To list the IPv4 addresses associated with the host name www.companypro.net, you should use the following command:

  nslookup www.companypro.net

  This command will query the DNS servers to find the IP address associated with the hostname provided.If you want to ensure that it returns the IPv4 address, you can specify the-type=Aoption, which stands for Address records that hold IPv4 addresses1. However, thenslookupcommand by default should return the IPv4 address if available. To list the IPv4 addresses associated with the host namewww.companypro.net, you should use thenslookupcommand.

  Command: nslookup

  Target:www.companypro.net

  So, the completed command is:

  nslookupwww.companypro.net

  nslookup: This command is used to query the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record. www.companypro.net: This is the domain name you want to query to obtain its associated IP addresses.
