Question 1

You want to store files that will be accessible by every user on your network. Which endpoint device do you need?

Accepted Answer

To store files that will be accessible by every user on a network, you would need a server. 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.

? 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 2

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?

Accepted Answer

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

•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. References:

Question 3

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.

Accepted Answer

•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.

Question 4

An engineer configured a new VLAN named VLAN2 for the Data Center team. When the team tries to ping addresses outside VLAN2 from a computer in
VLAN2, they are unable to reach them. What should the engineer configure?

Accepted Answer

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.

•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.

Question 5

DRAG DROP
Move each protocol from the list on the left to its correct example on the right.

Accepted Answer

The correct matching of the protocols to their examples is as follows:
? DHCP: Assign the reserved IP address 10.10.10.200 to a web server at your company.
? DNS: Perform a query to translate companypro.net to an IP address.
? ICMP: Perform a ping to ensure that a server is responding to network connections.
Here??s how each protocol corresponds to its example:
? DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to
devices on a network. In this case, DHCP would be used to assign the reserved IP address 10.10.10.200 to a web server.
? DNS (Domain Name System) is used to translate domain names into IP
addresses. Therefore, to translate companypro.net to an IP address, DNS would be utilized.
? ICMP (Internet Control Message Protocol) is used for sending error messages and
operational information indicating success or failure when communicating with another IP address. An example of this is using the ping command to check if a
server is responding to network connections.
These protocols are essential for the smooth operation of networks and the internet.
? Perform a query to translate companypro.net to an IP address.
? Assign the reserved IP address 10.10.10.200 to a web server at your company.
? Perform a ping to ensure that a server is responding to network connections.
? DNS (Domain Name System): DNS translates human-friendly domain names like "companypro.net" into IP addresses that computers use to identify each other

/100-150-exam/ (40 Q&As)
on the network.
? DHCP (Dynamic Host Configuration Protocol): DHCP automatically assigns IP addresses to devices on a network, ensuring that no two devices have the same
IP address.
? ICMP (Internet Control Message Protocol): ICMP is used for diagnostic or control
purposes, and the ping command uses ICMP to test the reachability of a host on an IP network.

Question 7

Which command will display all the current operational settings configured on a Cisco router?

Accepted Answer

Router
The show running-config command is used on a Cisco router to display the current operational settings that are actively configured in the router??s RAM. This
command outputs all the configurations that are currently being executed by the router, which includes interface configurations, routing protocols, access lists, and
other settings. Unlike show startup-config, which shows the saved configuration that the router will use on the next reboot, show running-config reflects the live,
current configuration in use.
References := The information is supported by multiple sources that detail the use of Cisco commands, particularly the show running-config command as the
standard for viewing the active configuration on a Cisco device123.
? show running-config: This command displays the current configuration running on the router. It includes all the operational settings and configurations applied to
the router.

/100-150-exam/ (40 Q&As)
? show protocols: This command shows the status of configured protocols on the
router but not the entire configuration.
? show startup-config: This command displays the configuration saved in NVRAM, which is used to initialize the router on startup, but not necessarily the current
running configuration.
? show version: This command provides information about the router's software version, hardware components, and uptime but does not display the running
configuration.

Question 8

A support technician examines the front panel of a Cisco switch and sees 4 Ethernet cables connected in the first four ports. Ports 1, 2, and 3 have a green
LED. Port 4 has a blinking green light. What is the state of the Port 4?

Accepted Answer

On a Cisco switch, a port with a blinking green LED typically indicates that the port is up (active) and is currently transmitting or receiving data. This is a normal
state indicating active traffic on the port.
•A. Link is up with cable malfunctions: Usually indicated by an amber or blinking amber light.
•B. Link is up and not stable: Not typically indicated by a green blinking light.
•D. Link is up and there is no activity: Would be indicated by a solid green light without blinking.
Thus, the correct answer is C. Link is up and active. References :=

Question 9

A local company requires two networks in two new buildings. The addresses used in these networks must be in the private network range.
Which two address ranges should the company use? (Choose 2.) Note: You will receive partial credit for each correct selection.

Accepted Answer

The private IP address ranges that are set aside specifically for use within private networks and not routable on the internet are as follows:
? Class A: 10.0.0.0 to 10.255.255.255
? Class B: 172.16.0.0 to 172.31.255.255
? Class C: 192.168.0.0 to 192.168.255.255
These ranges are defined by the Internet Assigned Numbers Authority (IANA) and are used for local communications within a private network123.
Given the options: A. 172.16.0.0 to 172.31.255.255 falls within the Class B private range.
* B. 192.16.0.0 to 192.16.255.255 is not a recognized private IP range. C. 11.0.0.0 to 11.255.255.255 is not a recognized private IP range. D. 192.168.0.0 to
192.168.255.255 falls within the Class C private range.
Therefore, the correct selections that the company should use for their private networks are

Question 10

DRAG DROP
Examine the connections shown in the following image. Move the cable types on the right to the appropriate connection description on the left. You may
use each cable type more than once or not at all.

/100-150-exam/ (40 Q&As)

Accepted Answer

Based on the image description provided, here are the cable types matched with the appropriate connection descriptions:
Connects Switch S1 to Router R1 Gi0/0/1 interface Cable Type: = Straight-through UTP Cable
Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit Cable Type: = Fiber Optic Cable
Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1 Cable Type: = Crossover UTP Cable Connects Switch S3 to Server0 network interface card Cable Type: =
Straight-through UTP Cable
The choices are based on standard networking practices where:
? Straight-through UTP cables are typically used to connect a switch to a router or a network interface card.
? Fiber optic cables are ideal for long-distance, high-speed data transmission, such as connections through an underground conduit.
? Crossover UTP cables are used to connect similar devices, such as router-to- router connections.
These matches are consistent with the color-coded cables in the image: green for switch connections, yellow for router-to-router connections within the same rack,
and blue for inter-rack connections. The use of these cables follows the Ethernet cabling standards.
? Connects Switch S1 to Router R1 Gi0/0/1 interface:
? Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit:
? Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1:
