- C. The system-cpu-policer acts on the aggregate traffic from all line cards.
- D. Hierarchical policing of control plane traffic is supported.
Answer: A
Explanation:
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.
NEW QUESTION # 14
Which of the following statements about IP-VRFs in Nokia's SR Linux is FALSE?
- A. Packets in an IP-VRF are forwarded based on the destination IP address.
- B. An IP-VRF is a Layer 3 network instance.
- C. Multiple servers can be connected to the same subnet in an IP-VRF.
- D. The router maintains a distinct route table for each IP-VRF instance.
Answer: C
Explanation:
Multiple servers connected to the same subnet typically reside within the same Layer 2 domain or MAC-VRF. IP-VRFs operate at Layer 3 and segment routing and forwarding by separate routing tables, so multiple servers on the same subnet are not a function of IP-VRF.

Answer: B
Explanation:
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.
NEW QUESTION # 17
How are LLDP frames advertised between two Nokia SR Linux routers?
- A. They are routed to the destination node based on the IP VRF forwarding table.
- B. They are forwarded to the destination node based on the MAC VRF table.
- C. They are periodically flooded to the broadcast MAC address on each interface.
- D. They are forwarded to the destination node based on the MAC VRF table.
Answer: B
Explanation:
LLDP frames are periodically sent to a well-known multicast MAC address on each interface to discover directly connected devices.
NEW QUESTION # 18
Which of the following is NOT one of the characteristics of Nokia's SR Linux?

- B. It uses mature and stable SNMP protocol to access the command line interface.
- C. It includes a NetOgs development kit that supports the integration of third-party applications.
- D. It uses a modular, state-driven architecture that gives applications efficient access to system information.
Answer: B
Explanation:
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.

Which of the following is NOT a valid logging source used in Nokia's SR Linux?
- A. Console
- B. SR Linux subsystem + priority
- C. Linux facility + priority
- D. Syslog filter
Answer: D
Explanation:
"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.
NEW QUESTION # 20
Which of the following is NOT a function of Nokia's SR Linux application manager?
- A. It translates the application's YANG model into protobufs for the IDB.
- B. It reads the application's configuration information and starts each application.
- C. It manages the SR Linux and customer-defined applications.
- D. It monitors the health of all applications.
Answer: A
Explanation:
The SR Linux application manager does not perform the function of translating an application's YANG model into protobufs for the Interface DataBase (IDB). Its primary roles are managing applications, reading their configuration, and monitoring their health.
NEW QUESTION # 21
Which of the following statements about Nokia's SR Linux logging is FALSE?
- A. Logging parameter configuration is translated into the /etc/rsyslog.conf file.
- B. SR Linux logs can be saved locally as an encrypted file.
- C. SR Linux logs are handled using facility Iocal6 of the native Linux syslog utility.
- D. SR Linux supports the use of filters to select log messages.
Answer: B
Explanation:
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.
NEW QUESTION # 22
Which of the following statements about resilient ECMP load balancing is TRUE?
- A. Hash buckets are used to ensure that flows egressing the same interface on one router use different egress interfaces on downstream routers.
- B. The hash value used to distribute traffic is calculated as a modulo function on specific fields of the packet header.
- C. A different hash seed is used on downstream routers to ensure that flows are randomly distributed across all eligible router interfaces.
- D. When one of the next-hops fail, only flows currently egressing to that next-hop are impacted.
Answer: D
Explanation:
In resilient ECMP load balancing, when a next-hop fails, only the flows that were using that specific next-hop are affected and need to be redistributed, minimizing disruption to other flows.
NEW QUESTION # 23
Which of the following statements about the MAC table shown in the exhibit output is FALSE?
- A. [interface ethernet-1/10 is configured with the MAC address 00:25:BA:00:00:10.
- B. The MAC address 00:25: BA:00:00:10 is learnt on more than one interface.
- C. Mac-duplication detection is enabled in mac-vrf-1.
- D. The MAC re-learning rate has exceeded the threshold within the specified time frame.
Answer: B
Explanation:
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.
NEW QUESTION # 24

Which of the following statements about using BFD with BGP is FALSE?
- A. The BFD endpoints agree on the send/receive rate of control packets.
- B. BGP is notified if several BFD control packets are missed.
- C. It can help rapidly detect link failures.
- D. Using BFD can speed up the BGP advertisement interval.
Answer: D
Explanation:
BFD helps detect link failures rapidly and notifies BGP to trigger route updates quickly, but it does not speed up the BGP advertisement interval itself. BGP advertisement intervals are controlled by BGP timers, not by BFD.
NEW QUESTION # 26
