QUESTION 131

Which option describes a difference between EIGRP for IPv4 and IPv6?

 

A.

Only EIGRP for IPv6 advertises all connected networks.

B.

Only EIGRP for IPv6 requires a router ID to be configured under the routing process-

C.

AS numbers are configured in EIGRP but not in EIGRPv3.

D.

Only EIGRP for IPv6 is enabled in the global configuration mode.

 

Correct Answer: B

Explanation:

Router ID – Both EIGRP for IPv4 and EIGRP for IPv6 use a 32-bit number for the EIGRP router ID. The 32-bit router ID is represented in dotted-decimal notation and is commonly referred to as an IPv4 address. If the EIGRP for IPv6 router has not been configured with an IPv4 address, the eigrp router-id command must be used to configure a 32-bit router ID. The process for determining the router ID is the same for both EIGRP for IPv4 and IPv6.

 

 

QUESTION 132

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.

 

Correct 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, the ping command is used to send an ICMP Echo Request to a target host name or IP ad
dress. 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 call ipconfig /all and receive a response, there is no need to ping the loopback address and your own IP address — 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:

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.

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 >

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 >

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

ping < IP address of remote host >

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

ping < Host name of remote host >

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 >

 

 

QUESTION 133

If host Z needs to send data through router R1 to a storage server, which destination MAC address does host Z use to transmit packets?

 

A.

the host Z MAC address

B.

the MAC address of the interface on R1 that connects to the storage server

C.

the MAC address of the interface on R1 that connects to host Z

D.

the MAC address of the storage server interface

 

Correct Answer: C

QUESTION 135

Which type of topology is required by DMVPN?

 

A.

ring

B.

full mesh

C.

hub-and-spoke

D.

partial mesh

 

Correct Answer: C

 

 

QUESTION 136

Which part of the PPPoE server configuration contains the information used to assign an IP address to a PPPoE client?

 

A.

virtual-template interface

B.

DHCP

C.

dialer interface

D.

AAA authentication

 

Correct Answer: C

Explanation:

PPPoE is configured as a point to point connection between two Ethernet ports. As a tunneling protocol, PPPoE is used as an effective foundation for the transport of IP packets at the network layer. IP is overlaid over a PPP connection and uses PPP as a virtual dial up connection between points on the network. From the user’s perspective, a PPPoE session is initiated by using connection software on the client machine or router. PPPoE session initiation involves the identification of the Media Access Control (MAC) address of the remote device. This process, also known as PPPoE discovery

 

 

QUESTION 137

Which statement about switch access ports is true?

 

A.

They drop packets with 802.1Q tags.

B.

A VLAN must be assigned to an access port before it is created.

C.

They can receive traffic from more than one VLAN with no voice support

D.

By default, they carry traffic for VLAN 10.

 

Correct Answer: A

Explanation:

“If an access port receives a packet with an 802.1Q tag in the header other than the access VLAN value, that port drops the packet without learning its MAC source address.”

 

 

QUESTION 138

You enter the show ipv6 route command on an OSPF device and the device displays a route. Which conclusion can you draw about the environment?

 

A.

OSPF is distributing IPv6 routes to BGP.

B.

The router is designated as an ABR.

C.

The router is designated as totally stubby.

D.

OSPFv3 is in use.

Correct Answer: A

 

 

QUESTION 139

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

 

Correct 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 the show ip interface brief command.

 

 

QUESTION 140

Which statement about DTP is true?

 

A.

It uses the native VLAN.

B.

It negotiates a trunk link after VTP has been configured.

C.

It uses desirable mode by default.

D.

It sends data on VLAN 1.

 

Correct Answer: D

Explanation:

Disabling Dynamic Trunking Protocol (DTP)

Cisco’s Dynamic Trunking Protocol can facilitate the automatic creation of trunks between two switches. When two connected ports are configured in dynamic mode, and at least one of the ports is configured as desirable, the two switches will negotiate the formation of a trunk across the link. DTP isn’t to be confused with VLAN Trunking Protocol (VTP), although the VTP domain does come into play.

 

clip_image004

 

DTP on the wire is pretty simple, essentially only advertising the VTP domain, the status of the interface, and it’s DTP type. These packets are transmitted in the native (or access) VLAN every 60 seconds both natively and with ISL encapsulation (tagged as VLAN 1) when DTP is enabled.
