C tbh, Cisco's LED logic is always inconsistent across models but blinking green is activity every time I see it.

Maya P. 1

Maybe B on this one. I always thought a blinking green LED could hint at some link instability or issues, especially if it’s not specified that the blink is regular. Some docs use blinking to show both activity and errors. Not 100 percent, but curious if anyone’s seen B in practice.

Q: 2

A Cisco switch is not accessible from the network. You need to view its running configuration. Which out-of-band method can you use to access it?

Option B is it. Console access is classic out-of-band since you’re not going over the network at all. If the switch isn’t reachable on the network, things like SSH and Telnet won’t work anyway. Pretty sure that’s what Cisco expects here. Disagree?

Ethan 5

Option B had something like this in a mock and console was the answer.

B . Only 192.168.200.13 actually fits in the 192.168.200.0/24 range since that subnet covers .200.0 up to .200.255. Seen similar questions in official guides and labs, so pretty confident here.

Ryan T. 3

Hard to say, B, since only 192.168.200.13 fits the .200.0/24 network. A is easy to pick by accident if you aren't double-checking that third octet-classic exam trap. Let me know if you think differently.

Q: 4

Which two pieces of information should you include when you initially create a support ticket? (Choose 2.)

C or D? Initial info usually means A and C since you need to describe the fault and when it occurs, but sometimes support wants to know what steps you've tried too. I think AC is right, unless they expect troubleshooting already started.

Logan W. 1

Initial info should always be about what the problem is and when it happens, so A and C.

nslookup www.companypro.net

Emma J. 6

Not dig, that's often where people slip up. nslookup www.companypro.net is correct for CCST.

Q: 6

HOTSPOT An app on a user's computer is having problems downloading dat a. 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.

I don't think you'd want "https" as the protocol here, since Wireshark works at the TCP level for ports like 7100. The trap is assuming protocol = https, but it's actually just tcp with port 7100. Anyone disagree?

Drew I. 3

Nah, not protocol https here, it should be tcp port 7100. Common trap is picking https since it's in the URL.

Q: 7

HOTSPOT Computers in a small office are unable to access companypro.net. You run the ipconfig command on one of the computers. The results are shown in the exhibit. You need to determine if you can reach the router. Which command should you use? Complete the command by selecting the correct options from each drop-down lists.

ping 192.168.0.1Had something like this in a mock, just need to ping the default gateway to check router reachability.

Emma O. 6

ping 192.168.0.1This checks if you have basic IP connectivity to the gateway router, ignoring any possible DNS issues. Pretty sure that's the intent since reaching the default gateway rules out a local network problem first. Agree with others here but open to other views.

Arjun D. 6

Nah, it's Entering code → Possession, Phone to face → Inference, Username/password → Knowledge. The tricky part is 'Inference' (usually 'Inherence').

CameronF 5

Entering a one-time security code → Possession, holding your phone to your face → Inference (biometrics), specifying username/password → Knowledge. That fits the standard MFA factors-something you have, something you are, something you know. Cisco sometimes uses 'Inference' instead of 'Inherence' for biometrics but it'

Correct Answer:

Examples Entering a one-time security code sent to your device after logging in: C. Possession Holding your phone to your face to be recognized: A. Inference Specifying your user name and password to log on to a service: B. Knowledge

Explanation

The correct matching of the MFA factors to their examples is as follows: Entering a one-time security code sent to your device after logging in: Possession Holding your phone to your face to be recognized: Inherence Specifying your user name and password to log on to a service: Knowledge Here’s why each factor matches the example: Possession: This factor is something the user has, like a mobile device. A one-time security code sent to this device falls under this category. Inherence: This factor is something the user is, such as a biometric characteristic. Facial recognition using a phone is an example of this factor. Knowledge: This factor is something the user knows, like a password or PIN. Multi-Factor Authentication (MFA) enhances security by requiring two or more of these factors to verify a user’s identity before granting access. Entering a one-time security code sent to your device after logging in. Factor: Possession Explanation: This factor relates to something you have, such as a device that receives a security code. Holding your phone to your face to be recognized. Factor: Inference (typically referred to as Inherence or Biometric) Explanation: This factor relates to something you are, such as biometric authentication like facial recognition. Specifying your username and password to log on to a service. Factor: Knowledge Explanation: This factor relates to something you know, such as a username and password. Possession Factor: This involves something the user has in their possession. Receiving a one-time security code on a device (e.g., phone) is an example of this. Inference Factor (Inherence/Biometric): This involves something inherent to the user, such as biometric verification (e.g., facial recognition or fingerprint scanning). Knowledge Factor: This involves something the user knows, such as login credentials (username and password).

DHCP → Assign reserved IP, DNS → Translate companypro.net, ICMP → Ping server. The main trap is folks sometimes confuse DHCP with DNS for address stuff, but pretty sure this is how it lines up. If you think differently let me know.

Correct Answer:

Examples Perform a query to translate companypro.net to an IP address: B. DNS Assign the reserved IP address 10.10.10.200 to a web server at your company: A. DHCP Perform a ping to ensure that a server is responding to network connections: C. ICMP

Explanation

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. DNS (Domain Name System): DNS is used to resolve domain names to IP addresses. Assign the reserved IP address 10.10.10.200 to a web server at your company. DHCP (Dynamic Host Configuration Protocol): DHCP is used to assign IP addresses to devices on a network. Perform a ping to ensure that a server is responding to network connections. ICMP (Internet Control Message Protocol): ICMP is used by network devices to send error messages and operational information, and it is the protocol used by the ping command. DNS (Domain Name System): DNS translates human-friendly domain names like "companypro.net" into IP addresses that computers use to identify each other 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.

Pretty textbook cabling for these types of connections. Switch to router and switch to server both use straight-through UTP, routers underground get fiber, and router-to-router is crossover. Can't see another way unless they're hiding a trick.

Nina C. 5

S1 to R1: Straight-through, R2 to R3 (underground): Fiber Optic, R1 to R2: Crossover, S3 to Server0: Straight-through. These follow Cisco standard wiring rules-straight-through for switch-to-router/server, crossover for router-to-router. Pretty sure that's it but let me know if you spot something off.

Correct Answer:

Connections Connects Switch S1 to Router R1 Gi0/0/1 interface: E. Straight-through UTP Cable Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit: D. Fiber Optic Cable Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1: C. Crossover UTP Cable Connects Switch S3 to Server0 network interface card: E. Straight-through UTP Cable

Explanation

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: Cable Type: Straight-through UTP Cable Explanation: A straight-through UTP cable is typically used to connect different types of devices, such as a switch to a router. Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduit: Cable Type: Fiber Optic Cable Explanation: Fiber optic cables are used for long-distance connections, such as those through an underground conduit between buildings. Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1: Cable Type: Crossover UTP Cable Explanation: A crossover UTP cable is typically used to connect similar devices directly, such as router to router connections. Connects Switch S3 to Server0 network interface card: Cable Type: Straight-through UTP Cable Explanation: A straight-through UTP cable is typically used to connect a switch to an end device, such as a server. Straight-through UTP Cable: Used to connect different devices (e.g., switch to router, switch to server). Crossover UTP Cable: Used to connect similar devices directly (e.g., router to router, switch to switch). Fiber Optic Cable: Used for long-distance and high-speed connections, often between buildings or data centers.
