NEW QUESTION # 92
Refer to the exhibit.
CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?
- A. Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.
- B. Confirm that IS-IS is running with metric-style narrow.

Answer: C
NEW QUESTION # 93
Refer to the exhibit.
An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?
- A. The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.
- B. The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.
- C. The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.
- D. The MED attribute can be applied on R2 to influence R1 to use it as the primary path.
Answer: B
Explanation:
Some level of load balancing is achieved by default as BGP prefers shortest AS_PATH for certain prefix (Cisco BGP path selection algorithm - rule 4) . If 1-7 rules gives no preference for certain prefix then with rule 8. Prefer lowest IGP metric to BGP next hop we can force traffic to R2 or R3 influencing load distribution.
NEW QUESTION # 94

- A. R1(config-router)#summary-address 1.0.0.0 255.0.0.0 level-1-2

- C. R1(config-router)#summary-address 1.0.0.0 255.0.0.0 level-
- D. R1(config-router)#no summary-address 1.0.0.0 255.0.0.0 level-1

NEW QUESTION # 95
Refer to the exhibit.
XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix.

Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?
- A. Option A
- B. Option D
- C. Option C
- D. Option B

Answer: A
NEW QUESTION # 97
Refer to the exhibit. A network engineer has divided AS into confederations. Due to repeated ASN, when the 10.0 0.0/8 prefix from R1 arrives to R2, BGP automatically rejects it. What should the engineer do to fix the problem so that BGP allows that prefix on R2?
- A. Configure the command as-override on R1.
- B. Configure the command allowas-in on all the PE routers.
- C. Configure the command as-override on R2.
- D. Configure the command allowas-in on R2.
