SWRE Unit 7 and 8 pt1

What can be concluded about the configuration shown on R1?

• • R1 is configured as a DHCPv4 relay agent.

• • R1 is operating as a DHCPv4 server.

• • R1 will broadcast DHCPv4 requests on behalf of local DHCPv4 clients.

• • R1 will send a message to a local DHCPv4 client to contact a DHCPv4 server at 10.10.10.8.

R1 has been configured as shown. However, PC1 is not able to receive an IPv4 address. What is the problem?​

• • R1 is not configured as a DHCPv4 server.​

• • The ip helper-address command was applied on the wrong interface.

• • A DHCP server must be installed on the same LAN as the host that is receiving the IP address.

• • The ip address dhcp command was not issued on the interface Gi0/1.

A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?

• • to restrict access to the WLAN by authorized, authenticated users only

• • to monitor the operation of the wireless network

• • to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range

• to reduce the risk of interference by external devices such as microwave ovens

Refer to the exhibit. Which statement shown in the output allows router R1 to respond to stateless DHCPv6 requests?

• • ipv6 nd other-config-flag​

• • prefix-delegation 2001:DB8:8::/48 00030001000E84244E70​

• • ipv6 dhcp server LAN1​

• • ipv6 unicast-routing

• ns-server 2001:DB8:8::8​

Which method of IPv6 prefix assignment relies on the prefix contained in RA messages?

• • EUI-64

• • SLAAC

• • static

• • stateful DHCPv6

Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?

• • broadcast DHCPACK

• • broadcast DHCPREQUEST

• • unicast DHCPACK

• • unicast DHCPREQUEST

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 echo request message to the DHCPv6 or SLAAC-learned address and if no reply is returned, the address is considered unique.

• • 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.

• • The host checks the local neighbor cache for the learned address and if the address is not cached, it it considered unique.

• • The host sends an ARP broadcast to the local link and if no hosts send a reply, the address is considered unique.

A network administrator has added a new subnet to the network and needs hosts on that subnet to receive IPv4 addresses from the DHCPv4 server.
What two commands will allow hosts on the new subnet to receive addresses from the DHCP4 server? (Choose two.)

• • R1(config-if)# ip helper-address 10.2.0.250

• • R1(config)# interface G0/1

• • R1(config)# interface G0/0

• • R2(config-if)# ip helper-address 10.2.0.250

• • R2(config)# interface G0/0
