Free Cisco CCST-Networking Exam Dumps Questions & Answers

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.

Correct Answer:

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 interfaceCable Type: = Straight-through UTP Cable Connects Router R2 Gi0/0/0 to Router R3 Gi0/0/0 via underground conduitCable Type: = Fiber Optic Cable Connects Router R1 Gi0/0/0 to Router R2 Gi0/0/1Cable Type: = Crossover UTP Cable Connects Switch S3 to Server0 network interface cardCable Type: = Straight-through UTP Cable The choices are based on standard networking practices where:
* Straight-through UTP cablesare typically used to connect a switch to a router or a network interface card.
* Fiber optic cablesare ideal for long-distance, high-speed data transmission, such as connections through an underground conduit.
* Crossover UTP cablesare 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.

A help desk technician receives the four trouble tickets listed below. Which ticket should receive the highest priority and be addressed first?

• A.  Ticket 4: Two users report that wireless access in the cafeteria has been down for the last hour.
• B.  Ticket 1: A user requests relocation of a printer to a different network jack in the same office. The jack must be patched and made active.
• C.  Ticket 2: An online webinar is taking place in the conference room. The video conferencing equipment lost internet access.
• D.  Ticket 3: A user reports that response time for a cloud-based application is slower than usual.

You plan to use a network firewall to protect computers at a small office.
For each statement about firewalls, select True or False.
Note: You will receive partial credit for each correct selection.

Correct Answer:

Explanation:
* A firewall can direct all web traffic to a specific IP address.
* True: Firewalls can be configured to perform Network Address Translation (NAT) and port forwarding, which can direct all web traffic (typically on port 80 and 443) to a specific internal IP address.
* A firewall can block traffic to specific ports on internal computers.
* True: Firewalls can be configured with access control lists (ACLs) or rules to block traffic to specific ports on internal computers, enhancing security by restricting unwanted or harmful traffic.
* A firewall can prevent specific apps from running on a computer.
* False: Firewalls typically control traffic flow and do not prevent specific applications from running on a computer. Application control is usually managed by endpoint security software or application control systems.
* Directing Web Traffic: Firewalls can manage traffic redirection using NAT and port forwarding rules to route web traffic to designated servers or devices within the network.
* Blocking Specific Ports: Firewalls can enforce security policies by blocking or allowing traffic based on port numbers, ensuring that only permitted traffic reaches internal systems.
* Application Control: While firewalls manage network traffic, preventing applications from running typically requires software specifically designed for endpoint protection and application management.

During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?

• A.  Data Link
• B.  Network
• C.  Session
• D.  Transport

A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network. The output of the command is shown as follows:

What can you tell from the command output?

• A.  The server with the address 192.168.1.10 is reachable over the network.
• B.  The router at hop 3 is not forwarding packets to the IP address 192.168.1.10.
• C.  The server address 192.168.1.10 is being blocked by a firewall on the router at hop 3.
• D.  Requests to the web server at 192.168.1.10 are being delayed and time out.
