Cisco CDCNID Cisco Data Center Networking Infrastructure Design Set 2

Do not permit route distribution with RHI. ✘ Run OSPF on all VLANs to reduce convergence time. ✘ Adjust OSPF reference bandwidth for VLANs with 10-Gigabit Ethernet links. ✘ Advertise all routes into a NSSA and summarize default routes out. ✔

fewer links ✘ better fault isolation ✘ more frequent switch upgrades ✘ simplified routing-protocol peering ✔

internal chassis connections ✘ cabling to 10/100 Ethernet ports on the blade switches ✘ cabling to Gigabit Ethernet ports on the blade switches ✘ cabling to 10-Gigabit Ethernet ports on the blade switches ✔

VACLs ✘ PVLANs ✘ Dynamic ARP Inspection ✘ Reverse Path Forwarding ✔

FWSM ✘ IDSM that is deployed in IDS mode ✘ IDSM that is deployed in IPS mode ✘ FWSM that is coupled with the NAM ✔

They do not support CEF720 line cards. ✘ All their FRUs are compatible with older Catalyst 6500 chassis. ✘ They require different Cisco IOS code trains than older Catalyst 6500 chassis. ✘ They support all existing supervisors, line cards, switch fabrics, and software releases. ✔

Power-over-Ethernet ✘ increased cooling capacity ✘ aggregation layer switching ✘ high-performance computing support ✔

bursty throughput and latency-sensitive ✘ bursty throughput but not latency-sensitive ✘ sustained moderate throughput and latency-sensitive ✘ sustained moderate throughput but not latency-sensitive ✔

loop-free with HSRP ✘ loop-free with GLBP ✘ loop-free with VRRP ✘ looped square with HSRP ✔ looped square with GLBP ✔

integrated blade server switches ✘ Cisco Catalyst 4948 Switch in a top-of-rack configuration ✘ Cisco Catalyst 4948 Switch in an end-of-rack configuration ✘ Cisco Catalyst 6506 Switch in an end-of-rack configuration ✔
