Which option must be enabled to allow line-rate forwarding on a Fibre Channel port?
Answer : C
Explanation:
Dedicated Rate Mode -
When port rate mode is configured as dedicated, a port is allocated required fabric bandwidth and related resources to sustain line rate traffic at the maximum operating speed configured for the port. In this mode, ports do not use local buffering and all receive buffers are allocated from a global buffer pool.

Explanation:
How is oversubscription between disk arrays and hosts calculated when you use only line-rate capable line cards?
Answer : B
Explanation:
Oversubscription is a networking term that is generally defined as the overall bandwidth ratio between host and storage array ports
Which type of device can be deployed to add multi-homing capability to an OTV implementation?
Answer : C
Explanation:
Multi-Homing -
One key function built in the OTV protocol is multi-homing where two (or more) OTV edge devices provide LAN extension services to a given site. As mentioned, this redundant node deployment, combined with the fact that STP BPDUs are not sent across the OTV overlay, may lead to the creation of an end-to-end loop:
Refer to the exhibit.
Answer : C
Explanation:
The fail action node least-bucket command assigns the failed node buckets to the active node with the least number of buckets after a node failure. For multiple node failures, this command determines the least-bucketed node and assigns all of the buckets of the failed node to the least-bucketed active node.
You are configuring a switch as a LISP xTR. You plan to use the LISP xTR when deploying redundant map servers.
Which action do you take?
Answer : B
Explanation:
Map-Server and Map-Resolver Considerations
The Map-Server and Map-Resolver are critical components in a LISP deployment. They provide capabilities to store and resolve the EID-to-RLOC mapping information for the LISP routers to enable routing between LISP sites.
The Map-Server is a network infrastructure component that learns EID-to-RLOC mapping entries from ETRs, which are authoritative sources and which publish
(register) their EID-to-RLOC mapping relationships with the Map-Server. A Map-Resolver is a network infrastructure component that accepts LISP-encapsulated
Map-Requests, typically from an ITR, and finds the appropriate EID-to-RLOC mapping by checking with a co-located Map-Server (typically) or by consulting the distributed mapping system.
This section discusses Map-Server and Map-Resolver deployment considerations for an enterprise data center LISP deployment. Note that you should deploy redundant standalone coexistent Map-Servers and Map-Resolvers. When redundant standalone Map-Servers and Map-Resolvers are deployed, all xTRs must register with both Map-Servers so that each has a consistent view of the registered LISP EID namespace. For Map-Resolver functions, use of an anycast address is desirable, because it will improve mapping lookup performance by choosing the Map-Resolver that is topologically closest to the requesting ITR.
