C. global configuration mode
D. BGP address-family configuration mode
Question 42
A remote operation center is deploying a set of I-BGP and E-BGP connections for multiple IOS-XR platforms using the same template. The I-BGP sessions exchange prefixes with no apparent issues, but the E-BGP sessions do not exchange routes. What causes this issue?
A. The I-BGP neighbors are mistyped and HELLO packets cannot be exchanged successfully between routers.
B. The E-BGP neighbors are not allowed to exchange Information due to the customer platform's default policy.
C. A PASS ALL policy has not been implemented for the I-BGP neighbors.
D. The next-hop-self command is not implemented on both E-BGP neighbors.
Question 43
Refer to the exhibit. An engineer is securing a customer's network. Which command must the engineer use to complete this configuration to prevent a DoS attack?
A. neighbor ttl-security
B. ebgp-multihop
C. neighbor ebgp-multihop
D. ttl-security
Question 44
What is the function of the FEC field within the OTN signal structure?
A. It allows the sending devices to apply QoS within the OTN forwarding structure.
B. It allows deep inspection of data payload fields.
C. It allows receivers to correct errors upon data arrival
D. It allows source nodes to discard payload errors before transmitting data on the network.
Question 45
A customer of an ISP requests support to setup a BGP routing policy. Which BGP attribute should be configured to choose specific BGP speakers as preferred points for the customer AS?
A. lowest multi-exit discriminator
B. highest local preference outbound
C. lowest local preference inbound
D. highest local preference inbound
Question 46
Which three OSPF parameters must match before two devices can establish an OSPF adjacency? (Choose three.)
A. IP address
B. subnet mask
C. interface cost
D. process ID
E. area number
F. hello timer setting
Question 47
Refer to the exhibit. Which condition must be met by the OSPF peer of router R1 before the two devices can establish communication?
A. The OSPF peer must use clear-text authentication.
B. The OSPF peer must be configured as an OSPF stub router.
C. The interface on the OSPF peer may have a different key ID, but it must use the same key value as the configured interface.
D. The interface on the OSPF peer must use the same key ID and key value as the configured interface.
Question 48
DRAG DROP -Drag and drop the OSPF area types from the left onto the correct statements on the right.Select and Place:
Question 49
Refer to the exhibit. Which statement about the neighbor statements for 192.168.1.1 is true?
A. The router sends BGP labels for its prefixes to this peer.
B. The router must have TDP configured for the send-label command to operate.
C. The neighbor router receives at least four labels from this router.
D. The router sends only a label for the prefix for Loopback0.
Question 50
Refer to the exhibit. Which statement about the status of the neighbor relationship between R1 and R2 is true?
A. The neighbor relationship is down because the two routers are configured with different area types.
B. The neighbor relationship is down because the two routers are in the same subnet.
C. The neighbor relationship is up because R2 is level 1 and Ievel 2 router.
D. The neighbor relationship is down because R2 is operating as a Level 1 router and the two routers are in different areas.
