Question 20

Which two application requirements are mandatory tor traffic to receive proper treatment when placed in the priority queue? (Choose two.)

Options:

small transactions (HTTP-like behavior)

WRED drop treatment

tolerance to packet loss

intolerance to jitter

TCP-based application

Question 21

Which two statements describe the usage of the IS-IS overload bit technique? (Choose two )

Options:

lf overload-bit is set on a Level 2 intermediate system, the other Level 2 intermediate systems in the topology will stop using the overloaded IS to forward Level 2 traffic However, the intermediate system can still forward Level 1 traffic

It can be set in intermediate systems (IS-IS routers) to prioritize control plane CSNP packets.

It can be used to automatically synchronize the link-state database between Level 1 intermediate systems

It can be set in intermediate systems (IS-IS routers) to avoid traffic black holes until routing protocols are fully converged after a reload operation.

It can be set in intermediate systems (IS-IS routers) to attract transit traffic from other intermediate systems

Question 22

Refer to the exhibit.

The network 10.10.0 .0/16 has been redistributed to OSPF processes and the best path to the destination from R1 has been chosen as R1-R2-R3 A failure occurred on the link between R2 and R3 and the path was changed to R1-R4-R5-R3 What happens when the link between R2 and R3 is restored'?

Options:

The path R1-R4-R5-R3 continues to be the best path because the metric is better

The path reverts back to R1-R2-R3 because the route type is E1

The path R1-R4-R5-R3 continues to be the best path because OSPF does not compare the metrics between two domains

The path reverts to R1-R2-R3 because this was the previous best path

Question 23

The network team in XYZ Corp wants to modernize their infrastructure and is evaluating an implementation and migration plan to allow integration MPLS-based, Layer 2 Ethernet services managed by a service provider to connect branches and remote offices. To decrease OpEx and improve

response times when network components fail, XYZ Corp decided to acquire and deploy new routers. The network currently is operated over E1 leased lines (2 Mbps) with a managed CE service provided by the telco.

Drag and drop the implementation steps from the left onto the corresponding targets on the right in the correct order.
