Question 1

Which of the following is NOT a valid logging source used in Nokia's SR Linux?

ALinux facility + priority

BConsole

CSR Linux subsystem + priority

DSyslog filter

Answer : D

'Syslog filter' is not a logging source; it is a mechanism used to filter log messages. Valid logging sources in SR Linux include Linux facility + priority, console, and SR Linux subsystem + priority.

Question 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.

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 3

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.

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 4

Examine the exhibit. Which of the following statements is TRUE?

AA recursive lookup is performed to resolve 10.2.1.0 to use 10.1.1.0.

BA recursive lookup is performed to resolve 10.1.1.0 to use 10.2.1.0.

CThe next-hop group for this static route is configured with two next-hops.

DThe next-hop selected for this route will be based on the preference value configured for each next-hop.

Answer : C

The static route shows two next-hop IP addresses (10.1.1.0 and 10.2.1.0) listed, indicating that a next-hop group with multiple next-hops is configured for load balancing or redundancy.

Question 5

Examine the exhibit. What type of information is NOT included in the IMET route advertised by VTEP1?

AVXLAN network identifier (VNI)

BFlooding list

CRoute distinguisher of VTEP1's MAC-VRF

DIP address of VTEP1

Answer : C

The IMET route includes the VNI, flooding list, and IP address of the originating VTEP, but it does not include the route distinguisher of the VTEP's MAC-VRF.

Question 6

Which of the following is NOT part of Day 2+ operations with Nokia's Fabric Services System?

AMonitor the data center fabric using model-driven telemetry.

BAnalyze the overall health of the data center fabric for proactive operations.

CUse the digital sandbox to test and validate configuration changes and upgrades.

DUse a fabric intent to build and validate design templates.

Answer : D

Using a fabric intent to build and validate design templates is primarily a Day 0 or Day 1 activity focused on initial fabric deployment and design, not part of Day 2+ operational tasks like monitoring, health analysis, or change validation.

Question 7

Which of the following statements about multi-homing in EVPN is FALSE?

AType 1 Ethernet Auto-Discovery (A-D) EVPN route is used to support EVPN multi-homing.

BType 4 Ethernet Segment (ES) EVPN route is used for designated forwarder (DF) election for an ES.

CThe ES identifier (ESI) uniquely identifies an ES and it is locally significant for a particular leaf.

DThe Ethernet Segment (ES) identifies a set of links that connects a host to one or more leafs.

Answer : C

The Ethernet Segment Identifier (ESI) uniquely identifies an Ethernet Segment (ES) globally across the EVPN domain, not just locally for a particular leaf.
