A. 10 Gigabit Ethernet is available on all switches and line cards, and blade switches for both data networks and storage networks..
B. Cisco has blade server switches for both data networking and storage networking requirements.
C. Cisco has a commitment to using Ethernet as the backbone connection system for the data center.
D. Cisco supports modular switches and top-of-rack switches for both Gigabit Ethernet and 10 Gigabit Ethernet, and blade switches for both data networks and storage networks.
A. Fiber optic cables should be used throughout the data center because they are less vulnerable to interception technology than copper cables.
B. Using 10 Gigabit Ethernet connections makes the speed of an attack from outside the corporation a significant security vulnerability, because reaction times to any intrusion must be 10 times faster than it is when using Gigabit Ethernet.
C. Security policies are fragmented across the data center, and there is no centralized point of management and control.
D. The data center does not need both intrusion detection systems and firewalls because they are complementary technologies and overlap in many respects.
