Refer to the exhibit.

Router 1. Router 2. and Router 3 are co-located in an onsite data center of an office, but Router 4. Router 5. and Router 6 are installed in another data center 'eral miles away A network engineer is troubleshooting an RSVP-TE issue on the network On most of the devices, the engineer can move all LSPs away from a selected interface and take it down for maintenance without interrupting traffic. However, when an interface on Router 3 is taken down, traffic on the network is disrupted What must the engineer enable to resolve the issue on Router 3?

A. FRR

B. NSR

C. soft-preemption feature

D. soft-disperse feature

C.    soft-preemption feature

Refer to the exhibit.

Company A established BGP sessions with several ISPs. A network engineer at the company must filter out all traffic except for routes that transit AS 152. The engineer configured the filtering policy “permit _152S_(_[0.9])” on R1, but after applying the configuration, the engineer notices that other routes are still visible. Which action resolves the issue?

A. Option A

B. Option B

C. Option C

D. Option D

A.    Option A

Refer to the exhibit.

EBGP peering is up between BGP AS 65101 and BGP AS 65201 The service provider expects traffic convergence within 300ms between the two autonomous systems but the network operations team sees that route and traffic convergence is too slow Which two actions improve the convergence time? (Choose two.)

A. Change the bfd multiplier value to 3 on routers RN and RM

B. Configure fall-over bfd under the BGP instance for BGP neighbors on RN

C. Configure bfd interval 50 min_rx 100 multiplier 6 on the connected interfaces on RN and RM

D. Configure bfd interval 50 min_rx 50 multiplier 6 on the connected interfaces on RL and RY

E. Change the bfd interval value to 100ms on routers RN and RM

A.   Change the bfd multiplier value to 3 on routers RN and RM
E.   Change the bfd interval value to 100ms on routers RN and RM

What is a restriction of 6PE?

A. It is implemented only over eBGP peers.

B. It is implemented only over iBGP peers.

C. It adds a value of ::FFFf:: on the IPv4 next hop address.

D. It cannot be implemented on VRFs.

D.    It cannot be implemented on VRFs.

Refer to the exhibit.

A network engineer must enable segment routing between the three autonomous systems with these requirements:

·OSPF link-state data for area 0 routers must be distributed to the controller via BGP LS.
·EPE must be enabled on the egress node in AS 100.
·Routers must advertise peer node SIDs to the controller R1 via BGP LS.

Which configuration must the engineer apply?

A. Option A

B. Option B

C. Option C

D. Option D

B.   Option B


Refer to the exhibit The branch office in area 10 is connected to HQ via Frame Relay uplinks with bandwidth constraints After a recent implementation of QoS on the R2 and R3 networks the system has been logging %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x224E321, alignment 0 messages To reduce traffic load and memory utilization on R2 and R3 the network engineer configured R1 to announce only one user subnet per location by issuing the summary address 192.168.0.0 255.255.248.0 command en R1 However, the engineer noticed that router R2 still has two routes and a summary address from HQ and R3 also has two routes from HQ Which two actions must the engineer take on R1 to fix the issue so that only one route is announced’ (Choose two.)

A. Configure the subnet range with the network command under the IS-IS process.

B. Configure RI as a Level 1 device.

C. Redistribute both routes into the ISIS process.

D. Configure a summary route for Level 1-Level 2 devices.

E. Configure a summary route for Level 1 devices.

D.   Configure a summary route for Level 1-Level 2 devices.
E.   Configure a summary route for Level 1 devices.

Refer to the exhibit.

A network engineer configured three new PE routers to expand the network. The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing. The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes. Which action resolves the issue?

A. On Router 1, redistribute the routes into IGP.

B. On Router 1, summarize internal routes between areas.

C. On Router 2, redistribute the routes into IGP.

D. On Router 2. summarize internal routes between areas.

D.   On Router 2. summarize internal routes between areas.

A network administrator working for a private service provider with an employee ID 4784 41 907 wants to configure timers for the BGP process on their Cisco IOS XE router Which configuration follows guideline timer recommendations and is a valid BGP timer deployment?

A. Option A

B. Option B

C. Option C

D. Option D

D.   Option D

Refer to the exhibit.

A network engineer implemented this segment routing configuration. Which statement about the output is true?

A. This range conflicts with the segment routing local block range.

B. The device must be reloaded for these ranges to be allocated and used.

C. The default segment routing global block range is being used on this device.

D. A nondefault segment routing global block range is being used on this device.

D.   A nondefault segment routing global block range is being used on this device.
