Cisco 350-501 Online Questions &
Answers
Question 161:
Which type of attack is an application attack?
A. ping of death B. ICMP (ping) flood C. HTTP flood D. SYN flood
C. HTTP flood
Explanation
Question 162:
What is the characteristic of the Tl-LFA?
A. It guarantees a loop-free path for all interfaces in the OSPf- super backbone . B. It applies on each area and instance and makes all the interfaces inherit the configuration C. It guarantees a loop-free path for all areas configured m OSPF D. It applies only on the instance and makes at the interfaces inherit the configuration
B. It applies on each area and instance and makes all the interfaces inherit the configuration
Explanation
TI-LFA can be configured on the instance, area, or interface. When configured on the instance or area, all interfaces in the instance or area inherit the configuration.
This configuration is being applied on an IOS XR router.
Which statement about this configuration is true?
A. It is used to enable gRPC. B. It is used to create a streaming subscription with a 600-second interval. C. It is used to set up configuration to poll network data. D. It is used to create a streaming subscription with a 60-Second interval.
D. It is used to create a streaming subscription with a 60-Second interval.
Explanation
The configuration sets up a telemetry subscription to collect and send data every 60 seconds, which is indicated by the sample-interval 60000 setting in the configuration. References: For more detailed information, please refer to the official Cisco documentation on Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) and the specific section on Telemetry Configuration.
Assume all other configurations are correct and the network is otherwise operating normally.
Which conclusion can you draw about the neighbor relationship between routers R1 and R2?
A. The neighbor relationship is up. B. The neighbor relationship will be up only if the two devices have activated the correct neighbor relationships under the IPv4 address family. C. The neighbor is down because the local-as value for R2 is missing in the R1 neighbor statement. D. The neighbor relationship is down because R1 believes R2 is in AS 65012.
D. The neighbor relationship is down because R1 believes R2 is in AS 65012.
Explanation
The configuration for R1 indicates a BGP neighbor relationship with a device in AS 65012. However, R2 is actually in AS 65000, leading to a mismatch in AS numbers. This discrepancy will prevent the establishment of a BGP neighbor relationship between R1 and R2.
Question 165:
In MPLS traffic engineering, which FRR operation swaps the label and pushes the backup label?
A. Merge Point B. Point of Local Repair C. Branch Point D. Mid-Point
B. Point of Local Repair
Explanation
Question 166:
Which OS uses a distributed subsystem architecture?
A. IOS XE B. IOS C. IOS XR D. CatOS
C. IOS XR
Explanation
Question 167:
An engineer working for a telecommunication company with an employee ID: 1234:56:789 must configure an OSPF router in a multivendor network so that it performs NSF in the event of a route processor switchover.
Which configuration must the engineer apply?
A. router ospf 1nsf cisco B. router ospf 1nsf cisco helper C. router ospf 1nsf ietf helper D. router ospf 1nsf ietf
D. router ospf 1nsf ietf
Explanation
In a multivendor network environment, it is essential to configure OSPF NSF with the IETF standard to ensure compatibility across different vendor devices. The command router ospf 1 nsf ietf enables OSPF NSF capability using the IETF standard, which facilitates uninterrupted forwarding during a route processor switchover.
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.
A. The router sends BGP labels for its prefixes to this peer.
Explanation
In OSPF, for two routers to establish communication, they must have the same key ID and key value on their interfaces. This ensures secure communication between the OSPF peers. The key ID and value are part of the OSPF authentication mechanism that helps in validating the identity of OSPF peers before exchanging routing information.

Question 169:
Which feature describes the adjacency SID?
A. It applies only to point-to-point links. B. It applies only to multipoint links C. It is locally unique D. It is globally unique.
Router 1 and Router 2 were installed in the data center Router 1 is the core router in the network, but it fails to establish an OSPF peering with Router 2, and customer traffic is unable to pass. Router 1 also reports an increase in CPU and memory usage. However, the CPU for R2 is stable.
Which action resolves this issue?
A. Change the MTU to 1524 on Router 1. B. Disable Cisco Express Forwarding on Router 2. C. Change the transport mode to WAN on Rooter 1. D. Enable MPLS on Router 2.
A. Change the MTU to 1524 on Router 1.
Explanation
The issue of Router 1 failing to establish an OSPF peering with Router 2, and the increase in CPU and memory usage can be attributed to a mismatch in MTU (Maximum Transmission Unit) sizes. In OSPF, for a successful adjacency to be formed, the MTU size on the interfaces that are trying to form this adjacency must match. In this case, changing the MTU to 1524 on Router 1 will make it compatible with Router 2, allowing OSPF peering to be established and customer traffic to pass through successfully.
