Sample Questions:
An R1 router requires an equal load balancing to reach the prefix 192.168.0.0/16 over two exit points: through R2 and R3 routers. Which two options must be configured on the R1 router to achieve this goal? (Choose two.)
The BGP maximum path feature must be configured on
The BGP PIC core must be enabled on R1
Weight, local-pref, MED, as-path length, origin, and the BGP next-hop IGP cost must be the same for the R2 and R3 IBGP updates to R1.
The BGP Link Bandwidth feature must be applied on R1.
BGP extended community exchange must be enabled between IBGP neighbors.
A service provider is using multicast flows to provide streaming video content to its customers. Video streams are sometimes interrupted, and network instability is determined to be the cause. Which action should the service provider take to decrease the burden on the router resources in an unstable unicast routing environment?
Reduce the volume of query messages.
Tune the RPF back off.
Increase the PIM hello hold timers.
Filter unnecessary SA messages.
Which are two major changes Sync E offers over traditional Ethernet to make it suitable for clock distribution? (Choose two.)
SyncE introduces the concept of Boundary Clocks and Transparent Clocks improving network scalability and accuracy of clock synchronization.
Industry standard that guarantee interoperability, since granular details, such as specific field values are specified.
A mandated clock accuracy of 4.6ppm. The ESMC protocol for clock selection, distribution, management, traceability, and failover.
High-priority synchronization packets so it can continually adjust its own oscillator.
Which are the four main functions of the Cisco IOS XR System Manager? (Choose four)
performs system monitoring
starts, restarts, and terminates processes in response to user configuration or RP failover
is responsible for the message-passing "bus" for inter process communication
acts as a central repository for all process-related information initiates disaster recovery based on the process health
invokes a dumper to collect a core dump when a process terminates abnormally
Which multicast feature listens multicast conversations maintaining a map in order to control which ports receive specific multicast traffic?
Bidirectional PIM
Source Specific Multicast
PIM assertion
IGMP snooping
