Question #4
Retef to the exhibit. This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m EIGRP domains do not affect the SPF runs within OSPF The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains Which technique accomplishes the requirement?

Which main IoT migration aspect should be reviewed for a manufacturing plant?
A. Sensors
B. Security
C. Applications
D. Wi-Fi Infrastructure
E. Ethernet Switches
View answer
Correct Answer: E
Question #6
Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?
A. After the initial timer exchang
B. R2 sets its transmission rate to the R1 Desired Min TX interval
C. After the initial timer exchang
D. R1 sets its transmission rate to the R2 Required Min RX interval
E. Timers renegotiate indefinitely, so the timer exchange phase never converges
F. R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set

Correct Answer: D
Question #7
Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture. How can this implementation be achieved?
A. Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value
B. Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs
C. Enable OSPF load-balancing over unequal cost path
D. Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includes external internal values
