Cisco 350-501 Exam Domains Q&A

Certified instructors verify every question for 100% accuracy, providing detailed, step-by-step explanations for each.

Question 1 Cisco 350-501
QUESTION DESCRIPTION:

350-501 Q1

Refer to the exhibit. An engineer must Implement a traceroute operation to verity the R1 point-to-multipoint LSP connections. The traceroute operation must return all labels and hop-by-hop IP addresses for destinations 10.20.0.1. 10.30.0.1, and 10.40.0.1. and the maximum number of hops is 4. Which command must be executed to meet the requirements?

  • A.

    traceroute mpls traffic-eng tunnel-mte 10 ttl 4

  • B.

    traceroute mpls traffic-eng tunnel-mte 10 responder-id 10.40.0.1

  • C.

    traceroute mpls ipv4 10.30.0.1/32 fee-type generic

  • D.

    traceroute mpls ipv4 10.20.0.1/32 ttl 4

Correct Answer & Rationale:

Answer: D

Explanation:

The command “traceroute mpls ipv4 10.20.0.1/32 ttl 4” is used to trace the route that packets take to get from the source to the destination in an MPLS network, specifically for IPv4 addresses with a maximum of 4 hops (Time To Live). This command will provide information on all labels and hop-by-hop IP addresses for the specified destinations, meeting the requirements stated in the question.

References  := For more detailed information, you can refer to the Implementing and Operating Cisco Service Provider Network Core Technologies training, which covers the configuration, verification, troubleshooting, and optimization of Service Provider IP network infrastructures, including MPLS operations

Question 3 Cisco 350-501
QUESTION DESCRIPTION:

A customer site is being connected to a Frame Relay network via a T1 link. The customer has a contract for 512 kbps service with a Tc value of 125 ms. Under peak line conditions, customer traffic can reach four times the contracted speed. Which QoS configuration must the service provider implement to limit the customer to the contracted values?

350-501 Q3

  • A.

    Option A

  • B.

    Option B

  • C.

    Option C

  • D.

    Option D

Correct Answer & Rationale:

Answer: B

Explanation:

The service provider must implement a QoS configuration that includes traffic policing to enforce the contracted bandwidth limits. Option B is the correct choice because it specifies a committed information rate (CIR) of 512 kbps, which matches the customer’s contracted rate. The configuration also includes a burst size that accommodates the Tc value of 125 ms, allowing for brief periods of higher traffic without dropping packets.  This setup ensures that under peak conditions, any traffic exceeding the contracted rate is either marked or dropped, thus preventing the customer from exceeding the agreed-upon bandwidth.  References  := For more detailed information on QoS configurations for Frame Relay networks, refer to the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course materials, which cover the principles of traffic policing and shaping in service provider environments

Question 4 Cisco 350-501
QUESTION DESCRIPTION:

Refer to the exhibit:

350-501 Q4

Which condition must be met by the OSPF peer of router R1 before the two devices can establish communication?

  • A.

    The interface on the OSPF peer must use the same key ID and key value as the configured interface

  • B.

    The interface on the OSPF peer may have a different key ID, but it must use the same key value as the configured interface

  • C.

    The OSPF peer must be configured as an OSPF stub router

  • D.

    The OSPF peer must use clear-text authentication

Correct Answer & Rationale:

Answer: A

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.  References : Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) -  Cisco SPCOR Training & Certification

Question 5 Cisco 350-501
QUESTION DESCRIPTION:

Exhibit:

350-501 Q5

However, local-preference configuration is not permitted on R1. Which task must the engineer perform on R1 to complete the implementation?

  • A.

    Configure the device to choose the best MED from the same AS.

  • B.

    Set the device to ignore the conditional MED if the route originated in a different autonomous system.

  • C.

    Enable MED comparison between routes from neighbors in different AS.

  • D.

    Implement deterministic MED to choose the best route from the different AS.

Correct Answer & Rationale:

Answer: C

Question 6 Cisco 350-501

Question 8 Cisco 350-501
QUESTION DESCRIPTION:

350-501 Q8

Refer to the exhibit. A network engineer is configuring router RB to secure BGP advertisements against route hijacking activity. RB must validate all prefixes that it receives from origin AS 200 before installing them in the BGP route table. Which configuration meets the requirement?

  • A.

    RB(config)# router bgp 100

    RB(config-router)# address-family ipv4 unicast

    RB(config-router-af)# bgp bestpath origin-as use validity

  • B.

    RB(config-bgp)# router bgp 100

    RB(config-bgp)# bgp origin-as validation signal ibgp

    RB(config-bgp)# bgp bestpath origin-as allow invalid

  • C.

    RB(config-bgp)# router bgp 100

    RB(config-bgp)# bgp origin-as validation time off

  • D.

    RB(config)# router bgp 100

    RB(config-router)# address-family ipv4 unicast

    PB(config-router-af)# bgp origin-as validation enable

Correct Answer & Rationale:

Answer: C

Question 9 Cisco 350-501
QUESTION DESCRIPTION:

Refer to the exhibit:

350-501 Q9

Which configuration prevents the OSPF neighbor from establishing?

  • A.

    mtu

  • B.

    duplex

  • C.

    network statement

  • D.

    default-metric

Correct Answer & Rationale:

Answer: A

Explanation:

The OSPF neighbor relationship is not establishing due to a mismatch in MTU (Maximum Transmission Unit) settings on the interfaces of PE-A and PE-B routers. On PE-A, there is no MTU configuration under the interface FastEthernet0/0, which means it is using the default MTU setting. However, on PE-B, the MTU is explicitly set to 1400 bytes with “ip mtu 1400” command under interface FastEthernet0/0. OSPF requires that both ends of a point-to-point link have matching MTU sizes to form a neighbor relationship; otherwise, OSPF adjacency will not be established.

Question 10 Cisco 350-501
QUESTION DESCRIPTION:

Refer to the exhibit.

350-501 Q10

An engineer configured BGP summarization on a customer ' s network. Which route is advertised to BGP peers?

  • A.

    192.0.0.0/16

  • B.

    192168.0.0/16

  • C.

    192.168.1.0/24

  • D.

    192168.0.5/30

Correct Answer & Rationale:

Answer: A

Explanation:

The configuration snippet in the exhibit shows that BGP summarization is configured with the “aggregate-address” command followed by an IP address and a subnet mask, and then the “summary-only” and “as-set” options. The IP address is 192.168.0.0, and the subnet mask is 255.255.0.0, which corresponds to a /16 prefix length (indicating that the first 16 bits of the IP address are the network portion). However, there seems to be a typo in option B as it’s not a valid IP address format; hence option A is correct with an assumption of typo error.
