Cisco CCST-Networking Practice Test Questions Answers

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.

The command that will display the output provided, which includes capability codes, local interface details, device IDs, hold times, and platform port ID capabilities, is the show cdp neighbor command. This command is used in Cisco devices to display current information about neighboring devices detected by Cisco Discovery Protocol (CDP), which includes details such as the interface through which the neighbor is connected, the type of device, and the port ID of the device1.

•Cisco - show cdp neighbors

The provided output is from the Cisco Discovery Protocol (CDP) neighbor table. The show cdp neighbor command displays information about directly connected Cisco devices, including Device ID, Local Interface, Holdtime, Capability, Platform, and Port ID.

•A. show mac-address-table: Displays the MAC address table on the switch.

•C. show inventory: Displays information about the hardware inventory of the device.

•D. show ip interface: Displays IP interface status and configuration.

Thus, the correct answer is B. show cdp neighbor.

Two home office computers are connected to a switch by Ethernet cables.

Network Type: LAN (Local Area Network)

Explanation: A LAN connects devices within a limited area such as a home, office, or building, using Ethernet cables or Wi-Fi.

Three government buildings in the same city connect to a cable company over coaxial cables.

Network Type: MAN (Metropolitan Area Network)

Explanation: A MAN connects networks across a city or campus, often using fiber optic or coaxial cables.

A cell phone connects to a Bluetooth headset.

Network Type: PAN (Personal Area Network)

Explanation: A PAN connects devices within a personal workspace, typically using wireless technologies like Bluetooth.

A financial institution connects its branches through a telecommunications service provider.

Network Type: WAN (Wide Area Network)

Explanation: A WAN connects multiple LANs over long distances, often using leased lines or satellite links provided by telecommunications companies.

LAN (Local Area Network): Used for connecting devices within a small geographical area such as a single building or home.

MAN (Metropolitan Area Network): Covers a larger geographical area than a LAN, typically a city or campus.

PAN (Personal Area Network): Connects devices within the range of an individual person, such as connecting a phone to a Bluetooth headset.

WAN (Wide Area Network): Spans large geographical areas, connecting multiple LANs across cities, countries, or continents.

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.

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.

=========================

•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.
