A DHCP-enabled client PC has just booted. During which two steps will the client PC use broadcast messages when communicating with a DHCP server? (Choose two.)
DHCPREQUEST
DHCPOFFER
DHCPACK
DHCPDISCOVER
DHCPNAK
An administrator issues the commands:
Router(config)# interface g0/1
Router(config-if)# ip address dhcp
What is the administrator trying to achieve?
configuring the router to resolve IP address conflicts
configuring the router to obtain IP parameters from a DHCPv4 server
configuring the router to act as a DHCPv4 server
configuring the router to act as a relay agent
Which DHCP IPv4 message contains the following information?
Destination address: 255.255.255.255
Client IPv4 address: 0.0.0.0
Default gateway address: 0.0.0.0
Subnet mask: 0.0.0.0
DHCPOFFER
DHCPACK
DHCPREQUEST
DHCPDISCOVER
What kind of message is sent by a DHCPv4 client requesting an IP address?
DHCPACK unicast message
DHCPDISCOVER broadcast message
DHCPDISCOVER unicast message
DHCPOFFER unicast message
What is the destination IP address when an IPv4 host sends a DHCPDISCOVER message?
224.0.0.1
127.0.0.1
255.255.255.255
0.0.0.0
If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?
request, discover, offer, acknowledgment
discover, offer, request, acknowledgment
acknowledgment, request, offer, discover
request, acknowledgment, discover, offer
Under which two circumstances would a router usually be configured as a DHCPv4 client? (Choose two.)
The administrator needs the router to act as a relay agent.
The router has a fixed IP address.
The router is meant to provide IP addresses to the hosts.
This is an ISP requirement.
The router is intended to be used as a SOHO gateway.
Which address does a DHCPv4 server target when sending a DHCPOFFER message to a client that makes an address request?
broadcast MAC address
client hardware address
gateway IP address
client IP address
What is the reason why the DHCPREQUEST message is sent as a broadcast during the DHCPv4 process?
for routers to fill their routing tables with this new information
for hosts on other subnets to receive the information
to notify other hosts not to request the same IP address
to notify other DHCP servers on the subnet that the IP address was leased
How does an IPv6 client ensure that it has a unique address after it configures its IPv6 address using the SLAAC allocation method?
It contacts the DHCPv6 server via a special formed ICMPv6 message.
It sends an ARP message with the IPv6 address as the destination IPv6 address.
It sends an ICMPv6 Neighbor Solicitation message with the IPv6 address as the target IPv6 address.
It checks with the IPv6 address database that is hosted by the SLAAC server.
What two methods can be used to generate an interface ID by an IPv6 host that is using SLAAC? (Choose two.)
EUI-64
DAD
ARP
stateful DHCPv6
random generation
Which command should be configured on a router interface to set the router as a stateful DHCPv6 client?
ipv6 address dhcp
ipv6 address autoconfigure
ipv6 enable
ipv6 dhcp server stateful
What message informs IPv6 enabled interfaces to use stateful DHCPv6 for obtaining an IPv6 address?
the ICMPv6 Router Advertisement
the DHCPv6 Reply message
the DHCPv6 Advertise message
the ICMPv6 Router Solicitation
In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?
ICMPv6
EUI-64
ARP
SLAAC
What process is used in ICMPv6 for a host to verify that an IPv6 address is unique before configuring it on an interface?
ARP
SLAAC
DAD
EUI-64
What are two characteristics of the SLAAC method for IPv6 address configuration? (Choose two.)
Router solicitation messages are sent by the router to offer IPv6 addressing to clients.
The default gateway of an IPv6 client on a LAN will be the link-local address of the router interface attached to the LAN.
IPv6 addressing is dynamically assigned to clients through the use of ICMPv6.
This stateful method of acquiring an IPv6 address requires at least one DHCPv6 server.
Clients send router advertisement messages to routers to request IPv6 addressing.
After booting, a client receives an ICMPv6 RA message with the M flag set to 0 and the O flag set to 1. What does this indicate?
The client should be statically configured with an IPv6 address because the local router does not support autoconfiguration.
The client should automatically configure an IPv6 address and then contact a DHCPv6 server for more information.
The client should automatically configure an IPv6 address without contacting a DHCPv6 server.
The client should request an IPv6 address directly from a DHCPv6 server.
A network administrator is entering the command ipv6 unicast-routing to start configuring DHCPv6 operation on a router. Which statement describes the function of this command?
It is required for enabling DNS service in DHCPv6 configurations.
It is required for sending ICMPv6 RA messages.
It is required to configure stateful DHCPv6 server on the router.
It is required to configure stateless DHCPv6 server on the router.
What is the purpose of HSRP?
It prevents malicious hosts from connecting to trunk ports.
It provides a continuous network connection when a router fails.
It prevents a rogue switch from becoming the STP root.
It enables an access port to immediately transition to the forwarding state.
Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?
HSRP
SLB
VRRPv2
GLBP
A network administrator is analyzing first-hop router redundancy protocols. What is a characteristic of VRRPv3?
It supports IPv6 and IPv4 addressing.
It works together with HSRP.
VRRPv3 is Cisco proprietary.
It allows load balancing between routers.
What is a potential disadvantage when implementing HSRP as compared to GLBP?
HSRP provides default gateway failover only when the active router fails.
HSRP does not have the capability to support IPv6 addresses.
HSRP does not provide load balancing with multiple active routers.
HSRP does not function in a multivendor environment.
A network engineer is configuring a LAN with a redundant first hop to make better use of the available network resources. Which protocol should the engineer implement?
GLBP
HSRP
VRRP
FHRP
When first hop redundancy protocols are used, which two items will be shared by a set of routers that are presenting the illusion of being a single router? (Choose two.)
IP Address
BID
hostname
static route
MAC Address
In FHRP terminology, what represents a set of routers that present the illusion of a single router to hosts?
standby router
forwarding router
virtual router
default gateway
A user needs to add redundancy to the routers in a company. What are the three options the user can use? (Choose three.)
STP
GLBP
VRRP
HSRP
