What are two functions of dynamic routing protocols? (Choose two.)

to maintain routing tables to discover the network

to make the Gi0/1 port a routed port

What is the purpose of ARP in an IPv4 network?

to obtain a specific MAC address when an IP address is known

What was the reason for the creation and implementation of IPv6?

to relieve IPv4 address depletion

transport layer

Refer to the exhibit. In what switch mode should port G0/1 be assigned if Cisco best practices are being used?

trunk

Refer to the exhibit. A network administrator has configured router CiscoVille with the above commands to provide inter-VLAN routing. What type of port will be required on a switch that is connected to Gi0/0 on router CiscoVille to allow inter-VLAN routing?

trunk port

When configuring a switch for SSH access, what other command that is associated with the login local command is required to be entered on the switch?

username username secret secret

Which two options are improvements provided by IPv6 as compared to IPv4? (Choose two.)

uses a simpler header to provide improved packet handling & increased the IP address space

What type of VLAN is designed to have a delay of less than 150 ms across the network?

voice VLAN

What type of VLAN is designed to reserve bandwidth to ensure IP Phone quality?

voice VLAN

Under which two occasions should an administrator disable DTP while managing a local area network? (Choose two.)

when connecting a Cisco switch to a non-Cisco switch/ on links that should not be trunking

True or False: 4 out of 5 RIRs no longer have enough IPv4 addresses to allocate to customers on a regular basis.

True

True or False? A router can be configured with a combination of both static routes and a dynamic routing protocol.

True

Which two route source codes are automatically created within a routing table whenever a router interface is configured with an IP address and activated? (Choose two.)

C L

True or False? IPv6 was designed with subnetting in mind.

True

VLANs can improve security by isolating sensitive data from the rest

True

VLANs improve network performance by segmenting broadcast

True

Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?

Cisco Express Forwarding

Which four steps are needed to configure a voice VLAN on a switch port? (Choose four).

Assign the voice VLAN to the switch port. Ensure that voice traffic is trusted and tagged with a CoS priority value. Add a voice VLAN. Configure the switch port in access mode.

What does a switch use to locate and load the IOS image?

BOOT environment variable

Which address type is not supported in IPv6?

Broadcast

Which statement is true about variable-length subnet masking?

The size of each subnet may be different, depending on requirements.

Which information does a switch use to keep the MAC address table information current?

The source MAC address and the incoming port

Which statement is correct about IPv4 packet header fields?

The source and destination IPv4 addresses remain the same while travelling from source to destination.

Which two statements describe a switch port that is configured with PortFast? (Choose two.)

The switch port should never receive BPDUs. The switch port immediately transitions from blocking to the forwarding state.

Refer to the exhibit. A router-on-a-stick configuration was implemented for VLANs 15, 30, and 45, according to the show running-config command output. PCs on VLAN 45 that are using the 172.16.45.0 /24 network are having trouble connecting to PCs on VLAN 30 in the 172.16.30.0 /24 network. Which error is most likely causing this problem?​

There is an incorrect IP address configured on GigabitEthernet 0/0.30.

Refer to the exhibit. A network administrator is reviewing port and VLAN assignments on switch S2 and notices that interfaces Gi0/1 and Gi0/2 are not included in the output. Why would the interfaces be missing from the output?

They are configured as trunk interfaces.

Which is a characteristic of static routes?

They are manually configured.

What is the purpose of frame buffers on a switch?

They hold traffic, thus alleviating network congestion.

A PC is configured to obtain an IP address automatically from network 192.168.1.0/24. The network administrator issues the arp -a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry?

This is a static map entry.

When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?

To the subinterface

How is traffic routed between multiple VLANs on a multilayer switch?

Traffic is routed via internal VLAN interfaces
