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?

• A.Option A
• B.Option B
• C.Option C
• D.Option D

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.

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?

• 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.
