A Complete Guide to ccna 200 125 study guide

Answer: B

Explanation:

Based on the output shown, the configured channel group number was 2 and the mode used was passive, so only choice B is correct.

Answer: A

Explanation:

This question is to examine the understanding of the interaction between EIGRP routers. The following information must be matched so as to create neighborhood.

EIGRP routers to establish, must match the following information:

1. AS Number;

2. K value.

Answer: A

Explanation:

The Point-to-Point Protocol (PPP) provides a standard method for transporting multi- protocol datagrams over point-to-point links. PPP was originally emerged as an encapsulation protocol for transporting IP traffic between two peers. It is a data link layer protocol (layer 2 in the OSI model)

Answer: A

Explanation:

The well-known formula to calculate OSPF cost is Cost = 108/ Bandwidth

Answer: F

Explanation:

The Spanning-Tree Protocol (STP) prevents loops from being formed when switches or bridges are interconnected via multiple paths. Spanning-Tree Protocol implements the 802.1D IEEE algorithm by exchanging BPDU messages with other switches to detect loops, and then removes the loop by shutting down selected bridge interfaces. This algorithm guarantees that there is one and only one active path between two network devices.

Answer: B,G

Explanation:

Since static routing is a manual process, it can be argued that it is more secure (and more prone to human errors) since the network administrator will need to make changes to the routing table directly. Also, in stub networks where there is only a single uplink connection, the load is reduced as stub routers just need a single static default route, instead of many routes that all have the same next hop IP address.

Answer: A,C,D

Explanation:

Benefits of VLANs

VLAN is a network structure which allows users to communicate while in different locations by sharing one multicast domain and a single broadcast. They provide numerousnetworkingbenefits and have become popular in the market. For instance, it helps reduce administrative costs when users are geographically dispersed.

1. Inexpensive

The popularity of VLANs is due to the fact that changes, adds, and moves can be attained simply by making necessary configurations on the VLAN port. Time-consuming, re- addressing, and host reconfigurations is now a thing of the past, because network configuration can be made at ease when need arises.

2. Better management

A VLAN typically solve the scalability issues that exist in a large network by breaking the main domain into several VLAN groups or smaller broadcast configurations, thereby encourage better control of multicast traffic as well as broadcast domains.

3. Improves network security

High-security can be positioned in different VLAN groups to ensure that non-members

cannot receive their broadcasts. On the other hand, a router is added and workgroups relocated into centralized locations.

4. Enhances performance

A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.

5. Segment multiple networks

VLANs are typically used to achieve multiple purposes. They are popularly used to reduce broadcast traffic. Each VLAN creates a separate, smaller broadcast domain.

6. Better administration

VLANs facilitate grouping of multiple geographical stations. When VLAN users move to another physical location, the network does not have to be configured.

Answer: A,B

Explanation:

A TRAP is a SNMP message sent from one application to another (which is typically on a remote host). Their purpose is merely to notify the other application that something has happened, has been noticed, etc. The big problem with TRAPs is that theyu2021re unacknowledged so you donu2021t actually know if the remote application received your oh-so- important message to it. SNMPv2 PDUs fixed this by introducing the notion of an INFORM, which is nothing more than an acknowledged TRAP.

Answer: C,F

Explanation:

The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model. DHCP servers assigns IP addresses from a pool of addresses and also assigns other parameters such as DNS and default gateways to hosts.

Answer: B

Explanation:

RSTP and STP operate on switches and are based on the exchange of Bridge Protocol Data Units (BPDUs) between switches. One of the most important fields in BPDUs is the Bridge Priority in which the MAC address is used to elect the Root Bridge -> RSTP operates at Layer 2 u2013 Data Link layer ->.
