Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?

DHCPREQUEST

Stateless DHCPv6

1. enabled in RA messages with the ipv6 nd other-config-flag command 2. clients send only DHCPv6 INFORMATION_REQUEST messages to the server 3. enabled on the client with the ipv6 address autoconfig command

Stateful DHCPv6

1. the M flag is set to 1 in RA messages 2. uses the address command to create a pool of addresses for clients 3. enabled on the client with the ipv6 address dhcp command

Refer to the exhibit. A network engineer is troubleshooting host connectivity on a LAN that uses a first hop redundancy protocol. Which IPv4 gateway address should be configured on the host?

192.168.2.100

The address pool of a DHCP server is configured with 192.168.184.0/26. The network administrator reserves 18 Ip address for access points. How many Ip address are left in the pool to be assigned to other hosts?

44

Refer to the exhibit. What protocol can be configured on gateway routers R1 and R2 that will allow traffic from the internal LAN to be load balanced across the two gateways to the Internet?

GLBP

a network administrator is analyzing the features that are supported by different first-hop router redundancy protocols. Which statement describes a feature that is associated with HSRP?

HSRP uses active and standby routers

What is an advantage of configuring a CIsco router as a relay agent?

IT can provide relay services for multiple UDP services

A company uses the method SLAAC to configure IPv6 addresses for the workstations of the employees. A network administrator configured the IPv6 address on the LAN interface of the router. The interface status is UP. However, the workstations on the LAN segment did not obtain the correct prefix and prefix length. What else should be configured on the router that is attached to the LAN segment for the workstations to obtain the information?​

R1(config)# ipv6 unicast-routing

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.What is the keyword that is displayed on www.netacad.com?

Router

which command will alow a network administrator to check the ip address that is assigned to a particular MAC address?

Router# show ip dhcp binding

Match the step number to the sequence of stages that occur during the HSRP failover process. (Not all options are used.)

The new forwarding router assumes both the IP and MAC- step 4 The standby router assumes the role of the forwarding router- Step 3 the forwarding router fails- Step 1 the standby router stops seeing hello messages from the forwarding router- Step 2

Refer to the exhibit. A network administrator is configuring a router as a DHCPv6 server. The administrator issues a show ipv6 dhcp pool command to verify the configuration. Which statement explains the reason that the number of active clients is 0?

The state is not maintained by the DHCPv6 server under stateless DHCPv6 operation.

Which FHRP implementation is a nonproprietary IPv4-only election protocol which has one master router per group?

VRRPv2

Match the FHRP protocols to the appropriate description. (Not all options are used.)

a Cisco proprietary FHRP that provides load sharing in addition to redundancy- GLBP a Cisco proprietary FHRP that provides redundancy through use of an active device and standby device- HSRP an open standard FHRP that provides redundancy through use of a virtual routers master and one or more backups- VRRP

Which command, when issued in the interface configuration mode of a router, enables the interface to acquire an IPv4 address automatically from an ISP, when that link to the ISP is enabled?

ip address dhcp

Which set of commnds will configure a router as a DHCP server that will assign IPv4 addresses to the 192.168.100.0/23 Lan while reserving the first 10 and the last address for static assignment?

ip dhcp excluded-address 192.168.100.1 192.168.100.10ip dhcp excluded-address 192.168.101.254ip dhcp pool LAN-POOL-100network 192.168.100.0 255.255.254.0default-router 192.168.100.1

Which statement describes HSRP

it is used within a group of routers for selecting an active device and a standby device to provide gateway services to a LAN

A client device on an Ethernet segments needs an IP address in order to communicate on the network. A DHCP server with IP address 192.168.1.1 has been configured and enabled on the network. How will a client device obtain a usable IP address for this network?

send a DHCPDISCOVER message to physcial address FF-FF-FF-FF-FF-FF

Match the DHCP message types to the order of the DHCPv4 process. (Not all options are used.)

step 1- DHCPDISCOVER step 2- DHCPOFFER step 3- DHCPREQUEST step 4- DHCPACK

What information can be verified through the show ip dhcp binding command?

the ipv4 addresses that are assigned to hosts by the DHCP server
