Answer:
Question 3Selectable Answer
Refer to the exhibit.
An engineer applied the summarization configuration on R1 for four networks
(192.168.20.0/24 to 192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes. While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2 .
Which configuration should the engineer apply on R1 to summarize routes?
Answer:
Question 4Selectable Answer
Refer to the exhibit.
A network engineer applied configuration on R1 to summarize all ISIS routes, but R2 Is still receiving specific routes from R1. The engineer has confirmed that both routers are configured with the correct summarization configuration, but R1 is not sending the correct summary routes .
Which configuration must be applied to router R1 to summarize routes within Level 1?
Answer:
Question 5Selectable Answer
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?
Answer:
Question 6Selectable Answer
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)
Answer:
Question 7Selectable Answer
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?
Answer:
Question 8Selectable Answer
Refer to the exhibit.
An engineer is troubleshooting a networking issue with several symptoms
✑ The shortest path from router R1 to R8 is underused and the longest path is overused
✑ Traffic from 10.1.1 1 to 10 8 8 8 is routed on the longest path
✑ Traffic between the R1 and the application server is experiencing packet drops and latency problems.
Which action resolves the issue?
Answer:
Question 9Selectable Answer
Refer to the exhibit.
An engineer working for a private telecommunication company with an employee id 4115 46 881 is enabling a segment routing solution with these requirements.
✑ A service provider is using the default range for prefix SID.
✑ PE1 must allocate the first SID from the default range for the loopback address
✑ PE1 and PE2 loopback SID allocation should have a minimum difference of 500.
Which configuration must be implemented to meet the requirements?
Answer:
Question 10Selectable Answer
Refer to the exhibit.
Which attribute can router 1 alter so that only other iBGP peers prefer to use 192.168.4.2 as the next hop for route 192.168.3.0/24?
Answer: Explanation:
Weight is local to the router while LP allows routers in an AS with multiple exit points to choose which exit point is used to reach a particular NLRI.
Question 11Selectable Answer
Refer to the exhibit.
Which statement about this configuration is true?
Answer:
Question 12Selectable Answer
Refer to the exhibit.
Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site .
Which action must be implemented to resolve the issues?
Answer:
Question 13Selectable Answer
Refer to the exhibit
After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3 Both FastEthemet interfaces on R2 and R3 are up and configured with the correct IP addresses MD5 password configured en R2 and R3 match with no issues.
