Question 1

The engineering team at ISP_1 must improve network stability time and minimize the impact of routing instabilities from other domains to unicast transit services in the backbone R1 is part of an OSPF- enabled network, and acts as an ASBR connected via interface GiO to the external domain The OSPF exponential backoff algorithm RFC 3623 with helper mode is already implemented on R1 Which additional configuration must the ISP_1 team apply to suppress routing instability for 3 minutes'?

Options :

A : Configure ip ospf resync-timtout 180 under the Gi0'1 interface configuration

B : Configure ip ospf timer nsf interval 3 under the global Gi0'1 interface configuration

C : Configure nsf ittf restart-inttrval 180 under the global OSPF configuration

D : Configure nsf ospf wait 3 under the global OSPF configuration

Answer: A

Question 2

What is used by SR-TE to steer traffic through the network?

Options :

A : shortest path calculated by IGP

B : dynamic rules

C : path policy

D : explicit maps

Answer: C

Question 3

Refer to the exhibit.

Refer to the exhibit. Customer A is a small media company with two offices connected by a 512 Kbps line. Their NY office is connected to several external partners by static routes on router R3. VoIP services use VoIP codec G729 Users reported poor voice quality and slow data transfer between the offices A network engineer configured ip tcp header-compression iphc-format on R2 and R3 routers Which additional action must the engineer take to fix the issue?

Options :

A : Configure the ip ospf I area O command under Serial 1/1 interfaces on R2 and R3 to avoid routing loops

B : Change the OSPF router ID on either router so that the router IDs are unique.

C : Configure the summary-address 10.10.0.0 255.255.240.0 command on R3 to optimize OSPF communication

D : Configure the BGP routing protocol between R2 and R3 to control route propagation.

Answer: C

Options :

A : It requires Cisco Express Forwarding to be enabled.

B : It must be enabled on loopback interfaces only

C : It requires OSPF to be configured on the network.

D : It must use an RP

Answer: D
