C.A DHCP client uses a gratuitous ARP to detect a DHCP server.
D.If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict.
E.If an address conflict is detected, the address removed from the pool for an amount of time configurable by the administrator.
F.If an address conflict is detected, the address is removed from the pool and will not be reused until server is rebooted.

A.HostA is not on the same subnet as its default gateway
B.The address of SwitchA is a subnet address
C.The Fa0/0 interface on RouterA is on a subnet that cannot be used
D.The serial interfaces of the routers are not on the same subnet
E.The Fa0/0 interface on RouterB is using a broadcast address
Refer to the exhibit。A problem with network connectivity has been observed.It is suspected that the cable connected to switch port Fa0/9 on Switch 1 disconnected.What would be an effect of tis cable being disconnected?()
A.Host B would not be able to access the server in VLAN9 until the cable is reconnected
B.For less than a minute ,Host B would not be able to access the server in VLAN9.Then normal network function would resume.
C.Communication between VLAN3 and the other VLANs would be disabled
D.The transfer of files from Host B to the server in VLAN9 would be significantly slower.
Refer to the exhibit. The network shown in the diagram is experiencing connectivity problems. Which of the following will correct the problems? ()
A.Configure the gateway on Host A as 10.1.1.1.
B.Configure the gateway on Host B as 10.1.2.254.
C.Configure the IP address of Host A as 10.1.2.2.
D.Configure the IP address of Host B as 10.1.2.2.
E.Configure the masks on both hosts to be 255.255.255.224.
F.Configure the masks on both hosts to be 255.255.255.240.
Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem?()
A.All of the routers need to be configured for backbone Area 1.
B.R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.
C.A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.
D.The hello and dead interval timers are not set to the same values on R1 and R3.
E.EIGRP is also configured on these routers with a lower administrative distance.
F.R1 and R3 are configured in different areas.
