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.
NEW QUESTION # 25
Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?
- A. It is more efficient than link-state protocols like IS-IS and OSPF.
- B. It supports both IPv4 and IPv6.
- C. It is a well understood and mature routing protocol.
- D. BGP neighbors automatically discover each other.
Answer: A
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 # 26
Which of the following statements about the CLI modes in Nokia's SR Linux is FALSE?
- A. Users can switch from one mode to another using the enter command.
- B. The show mode uses pre-defined reports to display operational information.
- C. The state mode displays the current configuration and operational information.
- D. The running mode is used to make configuration changes.
Answer: A
Explanation:
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.
NEW QUESTION # 27
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 are handled using facility Iocal6 of the native Linux syslog utility.
- C. SR Linux logs can be saved locally as an encrypted file.
- D. SR Linux supports the use of filters to select log messages.
Answer: C
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 # 28
Which of the following statements about a CPM-filter policer is FALSE?
- A. The system-cpu-policer is hardware-based.
- B. The system-cpu-policer acts on the aggregate traffic from all line cards.
- C. Hierarchical policing of control plane traffic is supported.
- D. CPM-filter entries can use both a distributed-policer and a system-cpu-policer.
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 # 29
Which of the following statements about the VXLAN tunneling in data centers is FALSE?
- A. VLXAN tunneling is used to provide Layer 2 connectivity between workloads over a common underlay network.
- B. Each VXLAN tunnel endpoint is automatically assigned with a unique VNI value.
- C. EVPN routes are exchanged between VXLAN tunnel endpoints.
- D. VXLAN tunnel endpoints can be on hypervisors, leaf routers, or datacenter gateways.
Answer: B
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 # 30
Which of the following is NOT one of the user types supported in Nokia SR Linux?
- A. Remote users
- B. Regular Linux OS users
- C. SR Linux users
- D. Container users
Answer: A
Explanation:
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.
NEW QUESTION # 31
Which of the following statements about a MAC-VRF is FALSE?
- A. Multiple devices can be connected to the same IP subnet using a MAC-VRF.
- B. A MAC-VRF is a Layer 2 network instance.
- C. Bridge table entries contain an exit interface for each destination address.
- D. Packets received in a MAC-VRF are forwarded based on destination IP address.
Answer: D
Explanation:
In a MAC-VRF, packets are forwarded based on Layer 2 information such as destination MAC addresses, not on destination IP addresses.
NEW QUESTION # 32
Which of the following statements about configuration checkpoints in Nokia SR Linux is FALSE?
- A. The operator can revert to any existing checkpoint.
- B. Checkpoint 0 is always the oldest checkpoint.
- C. The current running configuration can be saved as a JSON-formatted checkpoint file.
- D. The operator can generate a new checkpoint when committing configuration changes.
Answer: B
Explanation:
In Nokia SR Linux, checkpoint numbering is dynamic. The system assigns the lowest available number to the most recent checkpoint, not necessarily "0." When the number of saved checkpoints exceeds the configured maximum, the oldest checkpoint is removed, and the remaining checkpoints are renumbered accordingly. Therefore, checkpoint "0" is not always the oldest checkpoint.
NEW QUESTION # 33
Which of the following statements about Nokia's Fabric Services System is FALSE?
- A. Data center fabric configuration is represented as the fabric intent in a declarative YAML format.
- B. Cloud-native design enables easy integration with the customer's environment.
- C. Digital sandbox provides notification of performance issues in the data center fabric.
- D. Telemetry data is provided in a context that is relevant to the fabric intent.
Answer: C
Explanation:
The Digital Sandbox in Nokia's Fabric Services System is primarily used for simulation and validation of fabric intent, not for providing notifications of performance issues.
NEW QUESTION # 34
Based on the exhibit output, which of the following is NOT the reason the user runs the "baseline diff" command?
- A. User admin is not able to commit their changes.
- B. User admin notices that "!" appears in the CLI prompt.
- C. Another user has committed changes.
- D. User admin wants to check if there are differences between the current running config and their baseline datastore.
Answer: A
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 # 35
Which of the following statements about resilient ECMP load balancing is TRUE?
- A. The hash value used to distribute traffic is calculated as a modulo function on specific fields of the packet header.
- B. When one of the next-hops fail, only flows currently egressing to that next-hop are impacted.
- C. A different hash seed is used on downstream routers to ensure that flows are randomly distributed across all eligible router interfaces.
- D. Hash buckets are used to ensure that flows egressing the same interface on one router use different egress interfaces on downstream routers.
Answer: B
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.
