Question #41
Which CLI mode must be used to configure the BGP keychain in Cisco IOS XR Software?
  1. A
    routing configuration mode
  2. B
    BGP neighbor configuration mode
  3. C
    global configuration mode
  4. D
    BGP address-family configuration mode

Correct Answer:
C
chatbot-img GPT-4o - Answer
The correct mode for configuring the BGP keychain in Cisco’s IOS XR software is the BGP neighbor configuration mode, not the global configuration mode. This mode allows the configuration of security features specifically associated with individual BGP neighbors, such as assigning keychains for authentication purposes. Therefore, while a keychain can indeed be created generally within the global configuration mode, for BGP-specific applications, including the definition and linkage of the keychain to a particular BGP neighbor, the correct configuration context is within the BGP neighbor configuration mode. This distinction underscores the importance of context specificity in network configuration practices.

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?
  1. A
    The I-BGP neighbors are mistyped and HELLO packets cannot be exchanged successfully between routers.
  2. B
    The E-BGP neighbors are not allowed to exchange Information due to the customer platform's default policy.
  3. C
    A PASS ALL policy has not been implemented for the I-BGP neighbors.
  4. D
    The next-hop-self command is not implemented on both E-BGP neighbors.

Correct Answer:
B
chatbot-img GPT-4o - Answer
B) The correct choice here, regarding the E-BGP neighbors not exchanging routes, likely stems from the requirement for explicit routing policies on IOS-XR platforms. E-BGP sessions use different default security policies than I-BGP, primarily to prevent unintended routing announcements and acceptances. When no specific policies are configured for external connections, these sessions could appear inactive as no routes are exchanged. It is a subtle yet significant distinction, emphasizing the need for customized policy settings for each BGP session type, thus ensuring controlled and secure routing environments.

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?
  1. A
    neighbor ttl-security
  2. B
    ebgp-multihop
  3. C
    neighbor ebgp-multihop
  4. D
    ttl-security

Correct Answer:
D

Question #44
What is the function of the FEC field within the OTN signal structure?
  1. A
    It allows the sending devices to apply QoS within the OTN forwarding structure.
  2. B
    It allows deep inspection of data payload fields.
  3. C
    It allows receivers to correct errors upon data arrival
  4. D
    It allows source nodes to discard payload errors before transmitting data on the network.

Correct Answer:
C
chatbot-img GPT-4o - Answer
The FEC (Forward Error Correction) in the OTN signal structure plays a crucial role in ensuring data integrity over transmission. It allows receiver devices to correct errors that may have occurred during data transmission, enhancing overall network reliability and performance. This error-correction capability is essential in maintaining high-quality service levels over optical transport networks, where the signal can deteriorate due to various factors like transmission distance and optical interference.

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?
  1. A
    lowest multi-exit discriminator
  2. B
    highest local preference outbound
  3. C
    lowest local preference inbound
  4. D
    highest local preference inbound

Correct Answer:
D
chatbot-img GPT-4o - Answer
Absolutely, setting the highest local preference on inbound routes is the key to dictate how outbound traffic should exit your AS. This config essentially allows a network admin to prioritize which routes should be preferred for exiting traffic. It’s a strategic move to ensure traffic flows through the optimal paths, enhancing both performance and reliability. By bumping up the local preference, we're kind of putting a big 'prefer me' sign on those routes!

Question #46
Which three OSPF parameters must match before two devices can establish an OSPF adjacency? (Choose three.)
  1. A
    IP address
  2. B
    subnet mask
  3. C
    interface cost
  4. D
    process ID
  5. E
    area number
  6. F
    hello timer setting

Correct Answer:
BEF
chatbot-img GPT-4o - Answer
For two devices to establish OSPF adjacency, it’s critical their parameters align on specific settings. The correct parameters that must match include the subnet mask, area number, and hello timer setting. These ensure that both devices are in the same link-state area, can properly communicate on the same network segment, and maintain synchronized communication intervals, fundamental for OSPF operations. Matching these settings is key to forming a stable OSPF adjacency and effective routing exchanges.

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?
  1. A
    The OSPF peer must use clear-text authentication.
  2. B
    The OSPF peer must be configured as an OSPF stub router.
  3. 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.
  4. D
    The interface on the OSPF peer must use the same key ID and key value as the configured interface.

Correct Answer:
D

Question #49

Refer to the exhibit. Which statement about the neighbor statements for 192.168.1.1 is true?
  1. A
    The router sends BGP labels for its prefixes to this peer.
  2. B
    The router must have TDP configured for the send-label command to operate.
  3. C
    The neighbor router receives at least four labels from this router.
  4. D
    The router sends only a label for the prefix for Loopback0.

Correct Answer:
A

Question #50

Refer to the exhibit. Which statement about the status of the neighbor relationship between R1 and R2 is true?
  1. A
    The neighbor relationship is down because the two routers are configured with different area types.
  2. B
    The neighbor relationship is down because the two routers are in the same subnet.
  3. C
    The neighbor relationship is up because R2 is level 1 and Ievel 2 router.
  4. D
    The neighbor relationship is down because R2 is operating as a Level 1 router and the two routers are in different areas.

Correct Answer:
D
