A company uses DHCP servers to dynamically assign IPv4 addresses to employee workstations. The address lease duration is set as 5 days. An employee returns to the office after an absence of one week. When the employee boots the workstation, it sends a message to obtain an IP address. Which Layer 2 and Layer 3 destination addresses will the message contain?
The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned, the address is considered unique.
After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore usable?
DHCPACK------>The DHCP server confirming that the address lease has been accepted DHCREQUEST----->The client accepting the IP address provided by the DHCP server DHCPDISCOVER------->a Client initiating a message to find a DHCP server DHCPOFFER-------->A DHCP server responding to the initial request by a cient
Match each DHCP message type with its description. (Not all options are used.)
Router
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
192.168.2.100
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?
stateless DHCPv6
Refer to the exhibit. Based on the output that is shown, what kind of IPv6 addressing is being configured?
GLBP xplanation: GLBP, or Group Load Balancing Protocol, allows multiple routers to act as a single default gateway for hosts. GLBP load balances the traffic across the individual routers on a per host basis.
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?
MAC address of the virtual router
Refer to the exhibit. Which destination MAC address is used when frames are sent from the workstation to the default gateway?
118 Explanation: Calculate the maximum number of hosts available for the slash value and subtract the required static IP addresses required for the devices./24 = 254 hosts/25 = 126 hosts/26 = 62 hosts/27 = 30 hosts/28 = 14 hosts
The address pool of a DHCP server is configured with 10.92.71.0/25. The network administrator reserves 8 IP addresses for servers. How many IP addresses are left in the pool to be assigned to other hosts?
8
The address pool of a DHCP server is configured with 192.168.234.0/27. The network administrator reserves 22 IP addresses for IP phones. How many IP addresses are left in the pool to be assigned to other hosts?
the IPv4 addresses that are assigned to hosts by the DHCP server
What information can be verified through the show ip dhcp binding command?
Hot Standby Router Protocol (HSRP) is a Cisco-proprietary protocol that is designed to allow for transparent failover of a first-hop IPv4 device.
What is HSRP?
Workstations are assigned with IP addresses in the 169.254.0.0/16 network.
What is a result when the DHCP servers are not operational in a network?
easy IP address management
What is the reason that an ISP commonly assigns a DHCP address to a wireless router in a SOHO environment?
he Cisco router will exclude 15 IP addresses from being leased to DHCP clients.
What is the result of a network technician issuing the command ip dhcp excluded-address 10.0.15.1 10.0.15.15 on a Cisco router?
GLBP
Which FHRP implementation is a Cisco-proprietary protocol that suppports IPv4 load sharing?
GLBP for IPv6
Which FHRP implementation is a Cisco-proprietary protocol that suppports IPv6 load balancing?
Router# show ip dhcp binding
Which command will allow a network administrator to check the IP address that is assigned to a particular MAC address?
It is used within a group of routers for selecting an active device and a standby device to provide gateway services to a LAN.
Which statement describes HSRP?

Which set of commands 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 addresses for static assignment?
