New Cisco 200-125 Exam Dumps Collection (Question 11 - Question 20)

New Questions 11

Which standards-based First Hop Redundancy Protocol is a Cisco supported alternative to Hot Standby Router Protocol?

A. VRRP

B. GLBP

C. TFTP

D. DHCP

Answer: A


New Questions 12

Scenario:

You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.

Router R1 connects the main office to the internet, and routers R2 and R3 are internal routers.

NAT is enabled on router R1.

The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.

R1 sends the default route into RIPv2 for the internal routers to forward internet traffic to R1.

You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.

Why applications that are installed on PC's in R2 LAN network 10.100.20.0/24 are unable to communicate with server1?

A. A standard ACL statement that is configured on R1 is blocking the traffic sourced from Server1 network.

B. A standard ACL statement that is configured on R2 is blocking the traffic sourced from Setver1 network.

C. A standard ACL statement that is configured on R2 is blocking the traffic sourced from R2 LAN network.

D. A standard ACL statement that is configured on R1 is blocking the traffic sourced from R2 LAM network

New Questions 13

Which statement about Cisco Discovery Protocol is true?

A. It is a Cisco-proprietary protocol.

B. It runs on the network layer.

C. It can discover information from routers, firewalls, and switches.

D. It runs on the physical layer and the data link layer.

Answer: A


New Questions 14

While you were troubleshooting a connection issue, a ping from one VLAN to another VLAN on the same switch failed. Which command verifies that IP routing is enabled on interfaces and the local VLANs are up?

A. show ip interface brief

B. show ip nat statistics

C. show ip statistics

D. show ip route

Answer: A

Explanation:

Initiate a ping from an end device in one VLAN to the interface VLAN on another VLAN in order to verify that the switch routes between VLANs. In this example, ping from VLAN 2 (10.1.2.1) to Interface VLAN 3 (10.1.3.1) or Interface VLAN 10 (10.1.10.1). If the ping fails, verify that IP routing is enabled and that the VLAN interfaces status is up with theshow ip interface briefcommand.


New Questions 15

Refer to the exhibit.

Which statement describes the effect of this configuration?

A. The VLAN 10 VTP configuration is displayed.

B. VLAN 10 spanning-tree output is displayed.

C. The VLAN 10 configuration is saved when the router exits VLAN configuration mode.

D. VLAN 10 is added to the VLAN database.

Answer: D


New Questions 16

which three options are switchport configuration that can always avoid duplex mismatch errors between two switches? (Choose three.)

A. Set both sides of the connection to half duplex.

B. Set one side of the connection to auto-negotiate and the other side to full duplex.

C. Set both sides of the connection to auto-negotiate.

D. Set one side of the connection to auto-negotiate and the other side to half duplex.

E. Set one side of the connection to full ruplex and the other side to half duplex.

F. Set both sides of the connection to full duplex.

Answer: A,C,F


New Questions 17

On which type of device is every port in the same collision domain?

A. a router

B. a Layer 2 switch

C. a hub

Answer: C

Explanation:

Collision domain

A collision domain is, as the name implies, a part of a network where packet collisions can occur. A collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.


New Questions 18

What is the best way to verify that a host has a path to other hosts in different networks?

A. Ping the loopback address.

B. Ping the default gateway.

C. Ping the local interface address.

D. Ping the remote network.

Answer: D

Explanation:

Ping is a tool that helps to verify IP-level connectivity; PathPing is a tool that detects packet loss over multiple-hop trips. When troubleshooting, thepingcommand is used to send an ICMP Echo Request to a target host name or IP address. Use Ping whenever you want to verify that a host computer can send IP packets to a destination host. You can also use the Ping tool to isolate network hardware problems and incompatible configurations.

If you callipconfig /alland receive a response, there is no need to ping the loopback address and your own IP address u2014 Ipconfig has already done so in order to generate the report.

It is best to verify that a route exists between the local computer and a network host by first using ping and the IP address of the network host to which you want to connect. The command syntax is:

ping <IP address>

Perform the following steps when using Ping:

u2711 Ping the loopback address to verify that TCP/IP is installed and configured correctly on the local computer.

ping 127.0.0.1

If the loopback step fails, the IP stack is not responding. This might be because the TCP drivers are corrupted, the network adapter might not be working, or another service is interfering with IP.

u2711 Ping the IP address of the local computer to verify that it was added to the network

correctly. Note that if the routing table is correct, this simply forwards the packet to the loopback address of 127.0.0.1.

ping<IP address of local host>

u2711 Ping the IP address of the default gateway to verify that the default gateway is functioning and that you can communicate with a local host on the local network.

ping<IP address of default gateway>

u2711 Ping the IP address of a remote host to verify that you can communicate through a router.

ping<IP address of remote host>

u2711 Ping the host name of a remote host to verify that you can resolve a remote host name.

ping<Host name of remote host>

u2711 Run a PathPing analysis to a remote host to verify that the routers on the way to the destination are operating correctly.

pathping<IP address of remote host>


New Questions 19
