An enterprise network has two core routers that connect to 200 distribution routers and uses full-mesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process.
Which design solution is the most cost effective?
- A . Implement route reflectors on the two core routers
- B . Increase the memory on the core routers
- C . Implement e BGP between the core and distribution routers
- D . Increase the memory on the distribution routers
- E . Increase bandwidth between the core routers
Which management category is not part of FCAPS framework?

Which technology supports ant spoofing and does not have any impact on encryption performance regardless of packet size?
- A . MACsec
- B . IP source guard
- C . DHCP snooping with DAI
- D . IPsec
A network automation team plans to develop tasks to configure services on a network by using a Python controller. The configuration tasks must be implemented by using operations that support network-wide transactions. The candidate configuration must be validated automatically for all targeted devices before being applied to each specific device.
What can be used to apply the configuration to the network devices?
- A . RESTCONF/YANG
- B . NETCONF/YANG
- C . CLI over SSH
- D . XML Agent TTY

- A . controller interface
- B . southbound interface
- C . application programming interface
- D . northbound interface
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network.
Which layer accomplishes this design requirement?
- A . fault management
- B . accounting management
- C . performance management
- D . security management
You have been tasked with designing a data center interconnect as part of business continuity. You want to use FCoE over this DCI to support synchronous replication.

- E . IGP fast hello
Which design benefit of bridge assurance is true?
- A . It supposes a spanning-tee topology change upon connecting and disconnecting a station on a port
- B . It prevents switched traffic from traversing suboptimal paths on the network.
- C . It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.
- D . It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST + and MST
