Refer to the exhibit. OSPF is running as the IGP to provide reachability to all AS100 networks. R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal. Now BGP must be deployed within AS 100 because it will be receiving. Internet routes from its eBGP peers (the service provider) connected to R1 and R2.
What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

• A. R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must beredistributed at R1 and R2 into OSPF.
• B. Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another,and redistribution at R1 and R2.
• C. A full mesh should be deployed between all the routers with mutual redistribution to take place atR1 and R2.
• D. R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a routereflector.

Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites.

(Choose two.)

• A. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by thedistance between sites.
• B. VSANs must be routed between sites to isolate fault domains and increase overall availability.
• C. Synchronous data replication must be used to meet the business requirements
• D. Asynchronous data replication should be used in this scenario to avoid performance impact in theprimary site.
• E. VSANs must be extended from the primary to the secondary site to improve performance andavailability.

Answer: B

NEW QUESTION 9
Which design benefit of PortF ast is true?

• A. PortFast does not generate a spanning tree topology change hen a station on a port is connectedor disconnected
• B. PortFast disables spanning tree on the port, which puts the port into the forwarding stateimmediately after it is connected
• C. PortFast allows small, unmanaged switches to be plugged into ports of access switches withoutrisking switch loops
• D. PortFast detects one-way communications on the physical port, which prevents switch loops
• E. PortFast prevents switch loops that are caused by a unidirectional point to point link condition onRapid PVST+ and MST
• F. PortFast prevents switched traffic from traversing suboptimal paths on the network

Answer: A
