350-501 Free Practice Test

A network engineer is adding 10Gbps link to an existing 2X1Gbps LACP-based LAG to augment its capacity. Network standards require a bundle interface to be take out of service if one of its member links does down, and the new link must be added with minimal impact to the production network. Drag and drop the tasks that the engineer must perform from the left into the sequence on the right. Not all options are used.

An engineer is preparing to implement data plane security configuration. Which statement about this configuration is true?

1. A. Router 2 must configure a route to null 0 for network 192 168.1 0/24 for the RTBH implementation to be complete.
2. B. Router 1 is the trigger router in a RTBH implementation.
3. C. Router 1 must be configured with uRPF for the RTBH implementation to be effective.
4. D. Router 2 is the router receiving the DDoS attack

Correct Answer: B

Refer to the exhibit.

An engineer with an employee 10:4350:47:853 is implementing IS-IS as the new routing protocol in the network. All routers in the network operate as Level 2 routers in the same private autonomous system, and the three branches are connected via dark fibre. The engineer has already implemented IS-IS on router R1 with NET address 49.0133.532b.ca14.6915.21311.F40F.1B3a.ba10.00. Which IS-IS NET address configuration must be implemented on R3 to establish IS-IS connectivity?

1. A. 49.0133.532b.ca14.6915.21311.f40f.1b4a.bb87.00
2. B. 49.0135.332b.ca14.6975.28371.1721.1b3b.ca11.10
3. C. 48.0133.532b.ca14.6915.21311.f40f.1626.bb98.00
4. D. 49.0133.532b.ca14.6915.21311.1721.1b4a.0013.01

Correct Answer: A
IS-IS uses NET addresses to identify each router in the network, and the NET address of each router must be unique. In order for IS-IS to establish connectivity between R1 and R3, the NET address of R3 must be different from the NET address of R1, but it must also follow the same structure. In this case, the NET address of R1 is 49.0133.532b.ca14.6915.21311.F40F.1B3a.ba10.00, so the NET address of R3 must be 49.0133.532b.ca14.6915.21311.F40F.1B4a.bb87.00.

What is the characteristic of the Tl-LFA?

1. A. It guarantees a loop-free path for all interfaces in the OSPf- super backbone .
2. B. It applies on each area and instance and makes all the interfaces inherit the configuration
3. C. It guarantees a loop-free path for all areas configured m OSPF
4. D. It applies only on the instance and makes at the interfaces inherit the configuration

Correct Answer: A
