Question No. 1

Which of the following statements about the YANG model used in Nokia's SR Linux is FALSE?

AAll configuration and state information is defined as a YANG model.

BThe YANG model uses a tree structure with ''leafs'' as the branches and ''containers'' as the data components.

CThe YANG model can be converted into other formats such as JSON or XML.

DThe YANG model provides a standardized way for applications to retrieve SR Linux configuration and state information.

Show Answer

Correct Answer: B

In YANG models, 'leafs' are the data nodes (not branches), and 'containers' group related data nodes. The statement incorrectly reverses their roles by calling leafs branches and containers data components.

Question No. 2

Which of the following statements about a MAC-VRF is FALSE?

AA MAC-VRF is a Layer 2 network instance.

BBridge table entries contain an exit interface for each destination address.

CPackets received in a MAC-VRF are forwarded based on destination IP address.

DMultiple devices can be connected to the same IP subnet using a MAC-VRF.

Show Answer

Correct Answer: C

In a MAC-VRF, packets are forwarded based on Layer 2 information such as destination MAC addresses, not on destination IP addresses.

Question No. 3

Which of the following statements about the VXLAN tunneling in data centers is FALSE?

AVXLAN tunnel endpoints can be on hypervisors, leaf routers, or datacenter gateways.

BEVPN routes are exchanged between VXLAN tunnel endpoints.

CEach VXLAN tunnel endpoint is automatically assigned with a unique VNI value.

DVLXAN tunneling is used to provide Layer 2 connectivity between workloads over a common underlay network.

Show Answer

Correct Answer: C

VXLAN tunnel endpoints (VTEPs) are configured with VNI (VXLAN Network Identifier) values, but these VNIs are not automatically assigned; they must be explicitly configured to define Layer 2 segments.

Question No. 4

Which of the following statements about Nokia's SR Linux logging is FALSE?

ASR Linux logs are handled using facility Iocal6 of the native Linux syslog utility.

BSR Linux logs can be saved locally as an encrypted file.

CSR Linux supports the use of filters to select log messages.

DLogging parameter configuration is translated into the /etc/rsyslog.conf file.

Show Answer

Correct Answer: B

Nokia SR Linux does not natively support saving logs locally as encrypted files. Logs are managed using standard Linux syslog facilities and can be filtered, but encryption of local log files is not a built-in feature.

Question No. 5

Which of the following statements about a CPM-filter policer is FALSE?

AHierarchical policing of control plane traffic is supported.

BThe system-cpu-policer is hardware-based.

CThe system-cpu-policer acts on the aggregate traffic from all line cards.

DCPM-filter entries can use both a distributed-policer and a system-cpu-policer.

Show Answer

Correct Answer: B

The system-cpu-policer in Nokia SR Linux is software-based, not hardware-based. It acts on aggregate control plane traffic and supports hierarchical policing with CPM-filter entries using both distributed and system-cpu-policers.
