Please Help me with these Mutiple choices

Which of the following is/are true? O A A subnet with a netmask of 255.255.252.0 has more IP addresses than one with a netmask of 255.255.128.0 O B. A"/8, CIDR address contains 2"24 addresses. A single machine (for example, a laptop with both Ethernet card and wireless card) can have two IP addresses O D. A 8 CIDR address contains 2 8 addresses QUESTION 8 What are some advantages of using a NAT? A They block bad content (e.g. malware) from reaching your host B. They improve TCP performance by caching TCP connections to external hosts, thus reducing unnecessary three-way TCP handshakes OC. They allow a single public IP address to be shared among many hosts D They make it dificit for adversaries outside the NAT to open connections to hosts behind the NAT, thus offering a security benefits A malicious cient connects to the network This cilent is conf igured so that every milisecond,it sends DHCP discover messages into the network and issues request messages to the server that responds with an offer. The dlient does not release any address leases that it has been given. The server has 10,000 available addresses and issues leases for 24 hours Using this strategy, the cient can prevent others from connecing to the network and acquiring an IP address dynamically True False QUESTION4 Suppose that an ISP owns a subnet 18.2464.0/1& fthe ISPwants to create 4 disjoint,equaly-sized subnetworks from this, what will the CIDR adtresses of these subnets be? U 1824.8004. 1824.11204, 1824.9504, and 18.245404 18 246404, 18246408,182464 012 and 18 24640116 C18 2480020,1824 112020,18 2496020, and 18 2464020 u. 18.24.64.0/16, 18.24.80.0/16, 18.24.96.0/16, and 18.24.112.0/16
