Based on the exhibit output, which of the following statements is TRUE?
- A. An ACL filter is configured to accept ICMP packets, which are then processed by the tcpdump-like utility.
- B. A cpm-filter policer is configured to rate limit ICMP packets, which are then captured in a log file.
- C. capture-filter is configured to copy ICMP packets to the CPM where they are processed by the tcpdump-like utility.
- D. A cpm-filter is configured to accept ICMP packets, which are then captured in a log file.
Answer: C
Explanation:
The exhibit shows ICMP packets being captured and displayed by a tcpdump-like utility, which indicates that a capture-filter is configured to copy ICMP packets to the Control Plane Manager (CPM) where they are processed and monitored.
NEW QUESTION # 20
A static route is configured in two steps in Nokia's SR Linux. Which of the following items CANNOT be configured in the static-routes container?
- A. Preference value
- B. Next-hop group
- C. blackhole
- D. IPv4 destination prefix
Answer: C
Explanation:
The static-routes container in Nokia SR Linux does not support configuring a blackhole route directly; it is used to configure destination prefixes, preference values, and next-hop groups for static routing.
NEW QUESTION # 21
Which of the following statements about the MAC table shown in the exhibit output is FALSE?
- A. The MAC address 00:25: BA:00:00:10 is learnt on more than one interface.
- B. The MAC re-learning rate has exceeded the threshold within the specified time frame.
- C. Mac-duplication detection is enabled in mac-vrf-1.
- D. [interface ethernet-1/10 is configured with the MAC address 00:25:BA:00:00:10.
Answer: A
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 # 22
Which of the following Nokia's SR Linux ACLs is instantiated on all line cards to copy incoming packets to the CPM?
- A. CPM-filter ACL
- B. Ingress ACL
- C. Capture-filter ACL
- D. Egress ACL
Answer: A
Explanation:
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.
NEW QUESTION # 23
How are LLDP frames advertised between two Nokia SR Linux routers?
- A. They are periodically flooded to the broadcast MAC address on each interface.
- B. They are forwarded to the destination node based on the MAC VRF table.
- C. They are forwarded to the destination node based on the MAC VRF table.
- D. They are routed to the destination node based on the IP VRF forwarding table.
Answer: C
Explanation:
LLDP frames are periodically sent to a well-known multicast MAC address on each interface to discover directly connected devices.
NEW QUESTION # 24
Which of the following statements about the VXLAN tunneling in data centers is FALSE?
- A. VXLAN tunnel endpoints can be on hypervisors, leaf routers, or datacenter gateways.
- B. VLXAN tunneling is used to provide Layer 2 connectivity between workloads over a common underlay network.
- C. Each VXLAN tunnel endpoint is automatically assigned with a unique VNI value.
- D. EVPN routes are exchanged between VXLAN tunnel endpoints.
Answer: C
Explanation:
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.
NEW QUESTION # 25
Based on the exhibit output, which of the following is NOT the reason the user runs the "baseline diff" command?
- A. Another user has committed changes.
- B. User admin is not able to commit their changes.
- C. User admin wants to check if there are differences between the current running config and their baseline datastore.
- D. User admin notices that "!" appears in the CLI prompt.
Answer: B
Explanation:
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.
NEW QUESTION # 26
Examine the exhibit. What type of information is NOT included in the IMET route advertised by VTEP1?
- A. Flooding list
- B. Route distinguisher of VTEP1's MAC-VRF
- C. VXLAN network identifier (VNI)
- D. IP address of VTEP1
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.

"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 # 28
Which of the following statements about the YANG model used in Nokia's SR Linux is FALSE?
- A. The YANG model provides a standardized way for applications to retrieve SR Linux configuration and state information.
- B. The YANG model uses a tree structure with "leafs" as the branches and "containers" as the data components.
- C. All configuration and state information is defined as a YANG model.
- D. The YANG model can be converted into other formats such as JSON or XML.
Answer: B
Explanation:
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.
NEW QUESTION # 29
Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?
- A. BGP neighbors automatically discover each other.
- B. It is more efficient than link-state protocols like IS-IS and OSPF.
- C. It is a well understood and mature routing protocol.
- D. It supports both IPv4 and IPv6.
Answer: B
Explanation:
BGP is not chosen because it is more efficient than link-state protocols; in fact, link-state protocols like IS-IS and OSPF generally provide faster convergence and more efficient route calculation. BGP is used in data centers mainly because it is mature, well understood, supports both IPv4 and IPv6, and offers flexible policy control.
NEW QUESTION # 30
Which of the following statements about Zero Touch Provisioning (ZTP) is FALSE?
- A. The ZTP process is managed by the ZTP application in Nokia SR Linux.
- B. The ZTP process relies on a DHCP server for an IP address.
- C. ZTP allows a router to become operational in the network without any pre-provisioning.
- D. The ZTP process downloads a provisioning script defined in the TLS profile.
Answer: D
Explanation:
The ZTP process downloads a provisioning script typically from a defined URL or server, not from a TLS profile. The TLS profile is used for securing communications but does not define the provisioning script location.
