Cisco CCST-NETWORKING Exam Dumps

Correct Answer: C

The AAA service security model consists of three components: Authentication, Authorization, and Accounting.

-Authentication: This is the process of verifying the identity of a user or device. It ensures that only legitimate users can access the network or service.-Authorization: This determines what an authenticated user is allowed to do or access

within the network.

-Auditing/Accounting: This component tracks the actions of the user, including what resources they access and what changes they make.

Thus, the correct answer is C. Authentication.

Correct Answer: BD

-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.

Correct 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 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:

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:

Connects Switch S3 to Server0 network interface card:

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.
