The router has been configured with a supernet to accommodate the requirement for 380
users on
a subnet. The requirement already considers 30% future growth. Which configuration verifies
the IP subnet on router R4?
A. Subnet: 10.7.54.0
Subnet mask: 255.255.254.0
Broadcast address: 10.7.54.255
Usable IP address range: 10.7.54.1 – 10.7.55.254
B. Subnet: 10.7.54.0
Subnet mask: 255.255.254.0
Broadcast address: 10.7.55.255
Usable IP address range: 10.7.54.1 – 10.7.55.254
C. Subnet: 10.7.54.0
Subnet mask: 255.255.128.0
Broadcast address: 10.7.55.255
Usable IP address range: 10.7.54.1 – 10.7.55.254
D. Subnet: 10.7.54.0
Subnet mask: 255.255.255.0
Broadcast address: 10.7.54.255
Usable IP address range: 10.7.54.1 – 10.7.55.254
Answer:_B_Explanation'>Answer:
B
Explanation
380
users in a subnet < 512 = 2
9
. Therefore we need 9 bits 0 in the subnet mask ->
255.255.254.0. The increment is 2 (in the third octet) so the broadcast address is 10.7.55.255.
Question 6
What is a function of a Next-Generation IPS?
A. makes forwarding decisions based on learned MAC addresses
B. serves as a controller within
a controller-based network
C. integrates with a RADIUS server to enforce Layer 2 device authentication rules
D. correlates user activity
with network events
Answer:
D
Question 7
What is the difference between IPv6 unicast and anycast addressing?
A. An individual IPv6 unicast address is supported on a single interface on one node but an IPv6
anycast address is assigned to a group of interfaces on multiple nodes.
B. IPv6 unicast nodes must be explicitly configured to recognize the unicast address, but IPv6
anycast nodes require no special
configuration
C. IPv6 anycast nodes must be explicitly configured to recognize the
anycast address, but IPv6
unicast nodes require no special configuration
D. Unlike an IPv6 anycast address, an IPv6 unicast address is assigned to a group of interfaces
on
multiple nodes
