D. ip access-list standard Management permit 203.0.113.0 255.255.255.0
E. ip access-list extended Management permit tcp any range 22 23 203.0.113.0 0.0.0.255
How is noise defined in Wi-Fi?
A. measured difference between the desired Wi-Fi signal and an interfering Wi-Fi signal
B. any interference that is not Wi-Fi traffic that degrades the desired signal
C. signals from other Wi-Fi networks that interfere with the local signal
D. ratio of signal-to-noise rating supplied by the wireless device
What are two reasons to implement DHCP in a network? (Choose two.)
A. manually control and configure IP addresses on network devices
B. control the length of time an IP address is used by a network device
C. reduce administration time in managing IP address ranges for clients

Three switches must be configured for Layer 2 connectivity. The company requires only the designated VLANs to be configured on their respective switches and permitted across any links between switches for security purposes. Do not modify or delete VTP configurations.
The network needs two user-defined VLANs configured:
1.
VLAN 202: MARKETING
2.
VLAN 303: FINANCE
1.
Configure the VLANs on the designated switches and assign them as access ports to the interfaces connected to the PCs.
2.
Configure the e0/2 interfaces on Sw1 and Sw2 as 802.1q trunks with only the required VLANs permitted.
3.
Configure the e0/3 interfaces on Sw2 and Sw3 as 802.1q trunks with only the required VLANs permitted.

Tasks
Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.180.0/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:acca::/48 subnet.
1.
Using Ethernet0/1 on routers R1 and R2, configure the next usable /28 from the 192.168.180.0/24 range. The network 192.168.180.0/28 is unavailable.
2.
For the IPv4 /28 subnet, router R1 must be configured with the first usable host address.
3.
For the IPv4 /28 subnet, router R2 must be configured with the last usable host address.
4.
For the IPv6 /64 subnet, configure the routers with the IP addressing provided from the topology.
5.
A ping must work between the routers on the IPv4 and IPv6 address ranges.

IP connectivity between the three routers is configured. OSPF adjacencies must be established.
1.
Configure R1 and R2 Router IDs using the interface IP addresses from the link that is shared between them.
2.
Configure the R2 links with a max value facing R1 and R3. R2 must become the DR. R1 and R3 links facing R2 must remain with the default OSPF configuration for DR election. Verify the configuration after clearing the OSPF process.
3.
Using a host wildcard mask, configure all three routers to advertise their respective Loopback1 networks.
4.
Configure the link between R1 and R3 to disable their ability to add other OSPF routers.
