Your company designed a network to allow server VLANs to span all access switches in a data center In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches Which two features improve STP stability within the network design? (Choose two.)

1. A. BPDU guard on access ports
2. B. BPDU guard on the aggregation switch downlinks toward access switches
3. C. root guard on the aggregation switch downlinks toward access switches
4. D. root guard on access ports
5. E. edge port on access ports
6. F. access switch pairs explicitly determined to be root and backup root bridges

Correct Answer: AE

Refer to the exhibit.

This network is running EIGRP as the routing protocol and the internal networks are being advertised in EIGRP. Based on the link speeds, all traffic between London and Rome is getting propagated via Barcelona and the direct link between London and Rome is not being utilized under normal working circumstances. The EIGRP design should allow for efficiency in the routing table by minimizing the routes being exchanged. The link between London and Rome should be utilized for specific routes. Which two steps accomplish this task? (Choose two.)

1. A. Configure EIGRP route summarization on all the interfaces to summarize the internal LAN routes
2. B. Filter the routes on the link between London and Barcelona
3. C. Filter the routes on the link between London and Rome
4. D. Configure route leaking of summary routes on the link between London and Rome
