s that run Cisco IOS XR software?

A. between the active RP and the standby RP
B. between the active RP and the MSBs

Question No : 2

Cisco 642-775 question 2
Refer to the exhibit. A client asked you to help solve a problem This customer has two BGP
routers, each connected to its upstream provider. Because of administrative restrictions,
these two routers do not have an IBGP session between them, and each router
redistributes certain prefixes into OSPF and vice versa The customer would like to
preserve the AS path attribute for prefixes that cross the OSPF domain.
Which route-map set option will let the customer preserve the attribute?

A. set tag
B. set as-path
C. set as-path tag
D. set extcommunity


Question No : 3

Which statement accurately describes the BGP community filtering in Cisco IOS Software?

A. can be configured for IBGP neighbors only
B. can be configured for both IBGP and EBGP neighbors
C. can be configured for EBGP neighbors only
D. cannot be configured for IBGP or EBGP neighbors


Question No : 4

In an effort to decrease BGP convergence time, the BGP scan timer has been lowered.
What is possible side effect of this action?

A. There are slow or no responses to the console or Telnet sessions
B. Maximum packet-per-second throughput will increase.
C. Batch updates will be held for a shorter time
D. The BGP table can become out of sync with the rest of the network


Question No : 5

How often are complete sequence number PDUs sent by an IS-IS router to its neighbor on
a point to point link?

A. Once when the link comes up, and every 10 seconds thereafter
B. Once when the link comes up, and every 30 seconds thereafter.
C. Once when the link comes up, and every 60 seconds thereafter.
D. Once when the link comes up, and whenever there is a topology change


Question No : 6

Which is true when troubleshooting Cisco IOS XR Software by using the CLI?

A. Debug commands are less CPU-intensive than trace commands.
B. Trace uses a butter that is shared by all processes
C. Trace command logs will survive a system reboot, bill debug will not
D. Both trace and debug features need to be manually enabled when troubleshooting


Question No : 7

To improve BGP performance in your network, you would like to withdraw routes
immediately when the next hop of the route becomes unavailable instead of waiting for the
scan interval to detect the problem. Which Cisco IOS software command will configure this
failure?

A. bgp inject-map
B. bgp dampening
C. neighbor fall-over
D. import path selection
E. neighbor update-source


Question No : 8

Without using route reflectors or confederations, an AS with 20 routers will require how
many IBGP peerings?

A. 20
B. 45
C. 190
D. 200
E. 400


Question No : 9

Which keyword will stop further processing of the router policy language policy on a cisco
IOS router?

A. Stop
B. Quit
C. Drop
D. End
E. Exit


Question No : 10

What is the most significant BGP attribute that is used for path selection in Cisco IOS XR
Software?

A. MED
B. Weight
C. local preference
D. router ID


Question No : 11

Which two statements correctly describe the IBGP split-horizon rule?

A. Updates that are received on an EBGP session are forwarded to IBGP and EBGP.
B. Updates that are received on an EBGP session are not back out the EBGP peers that are in the same neighboring AS.
C. Updates that are received on an IBGP session are forwarded to all EGBP peers
D. Updates that are received on an IBGP session can be forwarded to other IBGP peers synchronization is turned off.


Question No : 12

Which command gathers information on BGP route instability in Cisco IOS XR Software?

A. show ip bgp summary
B. show bgp flap-statistics
C. show ip bgp neighbors
D. show bgp ip dampening


Question No : 13

What is the correct CLI hierarchy when configuring an interface for OSPF in Cisco IOS XR
software?

B. area, interface, router
C. router, area, interface
D. area, router, interface


Question No : 14

Which statement is correct regarding the BGP Fast Peering Session Deactivation feature?

A. improves the BGP convergence time by faster detection of router flaps
B. lowers the CPU usage by reducing the BGP scan time
C. allows BGP to detect an adjacency change and deactivate the terminated session in between standard CGP scanning intervals
D. allows a Cisco NSF-aware router to assist Cisco NSF-capable and Cisco NSF-aware neighbor to continue forwarding packets during a switchover operation


Question No : 15

Which Cisco IOS Software feature should you enable to monitor IGP neighbor flaps?

A. IP SLA
B. adjacency change logging
C. NetFlow
D. route dampening
E. control plane protection

Question No : 17

Cisco 642-775 question 17


Question No : 18

Refer to the exhibit.
Cisco 642-775 question 18
The Cisco IOS software platform PE1 has an interface Gigabit Ethernet 0/0 that is
connected to the Cisco IOS XR platform PE4 interface Gigabit Ethernet 0/4/0/2. OSPF
cannot establish an adjacency. What is possible solution to the problem?
