Question 1

Which of the following is NOT one of the characteristics of Nokia's SR Linux?

AIt uses an unmodified Linux kernel that simplifies the use of third party applications.

BIt uses a modular, state-driven architecture that gives applications efficient access to system information.

CIt includes a NetOgs development kit that supports the integration of third-party applications.

DIt uses mature and stable SNMP protocol to access the command line interface.

Answer : D

Nokia's SR Linux does not rely on the SNMP protocol for accessing the command line interface; instead, it uses modern, programmable interfaces aligned with its modular architecture.

Question 2

Which of the following statements about the CLI modes in Nokia's SR Linux is FALSE?

AThe state mode displays the current configuration and operational information.

BThe show mode uses pre-defined reports to display operational information.

CThe running mode is used to make configuration changes.

DUsers can switch from one mode to another using the enter command.

Answer : D

In Nokia SR Linux, users switch between CLI modes using specific commands like configure or exit, not an enter command. The enter command is not used for mode switching.

Question 3

Which of the following Nokia's SR Linux ACLs is instantiated on all line cards to copy incoming packets to the CPM?

ACapture-filter ACL

BCPM-filter ACL

CIngress ACL

DEgress ACL

Answer : B

The CPM-filter ACL is instantiated on all line cards in Nokia's SR Linux to copy incoming packets to the Control Plane Manager (CPM) for processing.

Question 4

Which of the following is NOT one of the user types supported in Nokia SR Linux?

ASR Linux users

BRegular Linux OS users

CContainer users

DRemote users

Answer : D

Nokia SR Linux supports SR Linux users, regular Linux OS users, and container users. 'Remote users' is not a defined user type within SR Linux user management.

Question 5

Based on the exhibit output, which of the following is NOT the reason the user runs the ''baseline diff'' command?

AUser admin is not able to commit their changes.

BAnother user has committed changes.

CUser admin wants to check if there are differences between the current running config and their baseline datastore.

DUser admin notices that ''!'' appears in the CLI prompt.

Answer : A

The 'baseline diff' command is used to compare the candidate configuration against the baseline datastore to see changes or conflicts, especially when multiple users are involved or to verify differences. It does not indicate that the user is unable to commit changes.

Question 6

Which of the following statements about the MAC table shown in the exhibit output is FALSE?

AThe MAC address 00:25: BA:00:00:10 is learnt on more than one interface.

BThe MAC re-learning rate has exceeded the threshold within the specified time frame.

C[interface ethernet-1/10 is configured with the MAC address 00:25:BA:00:00:10.

DMac-duplication detection is enabled in mac-vrf-1.

Answer : A

The MAC address 00:25:BA:00:00:10 is listed as 'duplicate,' but it appears only once associated with interface ethernet-1/10. Therefore, it is not learned on more than one interface.

Question 7

Based on the exhibit output, what CLI command can be used to display the contents of ''bgp-log'' in Nokia's SR Linux?

Ashow system logging buffer bgp-log

Bshow system logging file bgp-log

Cinfo system logging buffer bgp-log

Dinfo system logging file bgp-log

Answer : B

The 'bgp-log' is defined as a log file in the configuration, so the correct command to display its contents is show system logging file bgp-log.
