CCNA QUIZ 3- SEMETER 2

Which FHRP implementation is a Cisco-proprietary protocol that suppports IPv6 load balancing?

GLBP for IPv6

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

It can provide relay services for multiple UDP services.

Stateless DHCPv6

-enabled in RA messages with the ipv6 nd other-config-flag command -clients send only DHCPv6 INFORMATION-REQUEST messages to the server -enabled on the client with the ipv6 address autoconfig command

Stateful DHCPv6

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

The order of events that occur during the HSRP failover process.

1. The forwarding router fails. 2.The standby router stops seeing hello messages from the forwarding router. 3.The standby router assumes the role of the forwarding router. 4.The new forwarding router assumes both the IP and MAC addresses of the virtual router.

The address pool of a DHCP server is configured with 10.7.30.0/24. The network administrator reserves 5 IP addresses for printers. How many IP addresses are left in the pool to be assigned to other hosts?

249

What should be done to allow PC-A to receive an IPv6 address from the DHCPv6 server?

Add the ipv6 dhcp relay command to interface Fa0/0.

Which kind of message is sent by a DHCP client when its IP address lease has expired?​

DHCPREQUEST unicast message​

A network administrator configures a router to send RA messages with M flag as 0 and O flag as 1. Which statement describes the effect of this configuration when a PC tries to configure its IPv6 address?

It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information.

A small coffee shop is offering free Wi-Fi to customers. The network includes a wireless router and a DSL modem that is connected to the local phone company. What method is typically used to configure the connection to the phone company?

Set the WAN connection in the wireless router as a DHCP client.

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?

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.

C-A is unable to receive an IPv6 address from the stateful DHCPv6 server. What is the problem?

The ipv6 dhcp relay command should be applied to interface Gig0/0.

A network administrator is configuring a router for DHCPv6 operation. Which conclusion can be drawn based on the commands?

The router is configured for stateless DHCPv6 operation.

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

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?

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

Based on the output that is shown, what kind of IPv6 addressing is being configured?

stateless DHCPv6
