質問 # 17
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. Multiple servers can be connected to the same subnet in an IP-VRF.
- C. An IP-VRF is a Layer 3 network instance.
- D. The router maintains a distinct route table for each IP-VRF instance.
正解：B
解説：
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.
質問 # 18
Which of the following Nokia's SR Linux ACLs is instantiated on all line cards to copy incoming packets to the CPM?
- A. Ingress ACL
- B. Capture-filter ACL
- C. CPM-filter ACL
- D. Egress ACL
正解：C
解説：
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.
質問 # 19
Which of the following is NOT one of the characteristics of Nokia's SR Linux?
- A. It uses a modular, state-driven architecture that gives applications efficient access to system information.
- B. It uses an unmodified Linux kernel that simplifies the use of third party applications.
- C. It includes a NetOgs development kit that supports the integration of third-party applications.
- D. It uses mature and stable SNMP protocol to access the command line interface.
正解：D
解説：
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.
質問 # 20
Which of the following statements about configuration checkpoints in Nokia SR Linux is FALSE?
- A. The current running configuration can be saved as a JSON-formatted checkpoint file.
- B. The operator can generate a new checkpoint when committing configuration changes.
- C. Checkpoint 0 is always the oldest checkpoint.
- D. The operator can revert to any existing checkpoint.
正解：C
解説：
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.
質問 # 21
Which of the following is NOT how prefixes are typically learned and advertised in a leaf and spine data center?
- A. Spine routers advertise learned prefixes to leaf routers directly using eBGP.
- B. Spine routers learn prefixes from leaf routers directly using eBGP.
- C. Each leaf router learns the prefixes of remote servers from other leaf routers directly using eBGP.
- D. Each leaf router advertises the prefixes of its own locally connected servers.
正解：C
解説：
Leaf routers do not learn prefixes from other leaf routers directly using eBGP; instead, leaf routers learn remote prefixes via spine routers. The spine acts as the route reflector or intermediary between leaf routers.
質問 # 22
Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?
- A. It supports both IPv4 and IPv6.
- B. It is more efficient than link-state protocols like IS-IS and OSPF.
- C. BGP neighbors automatically discover each other.
- D. It is a well understood and mature routing protocol.
正解：B
解説：
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.
質問 # 23
Based on the exhibit output, what CLI command can be used to display the contents of "bgp-log" in Nokia's SR Linux?
- A. show system logging buffer bgp-log
- B. show system logging file bgp-log
- C. info system logging file bgp-log
- D. info system logging buffer bgp-log
正解：B
解説：
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.
質問 # 24
When autoboot flag is set in grub.cfg, which of the following is NOT performed as part of the Zero Touch Provisioning (ZTP) autoboot process?
- A. Uses the Web or FTP server to provide the RPM packages and any necessary images
- B. Uses Nokia's Fabric Services System to deploy the digital sandbox automatically
- C. Downloads and executes provisioning scripts
- D. Uses the DHCP server to provide the IP address and default gateway
正解：B
解説：
The ZTP autoboot process does not automatically use Nokia's Fabric Services System to deploy the digital sandbox; it focuses on network boot, DHCP IP assignment, and downloading/executing provisioning scripts from web or FTP servers.
質問 # 25
Examine the exhibit. Which of the following statements is TRUE?
- A. The next-hop selected for this route will be based on the preference value configured for each next-hop.
- B. The next-hop group for this static route is configured with two next-hops.
- C. A recursive lookup is performed to resolve 10.2.1.0 to use 10.1.1.0.
- D. A recursive lookup is performed to resolve 10.1.1.0 to use 10.2.1.0.
正解：B
解説：
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.
質問 # 26
Which of the following statements about SR Linux interfaces is FALSE?
- A. The loopback interface is a physical interface directly connected to another interface on the same chassis.
- B. Only one management interface is allowed.
- C. Layer 2 parameters such as MTU are configured at the SR Linux interface level while Layer 3 parameters are configured at the subinterface level.
- D. Network interfaces are associated with physical ports on the linecards.
正解：A
解説：
The loopback interface in SR Linux is a logical, virtual interface used for management and routing purposes; it is not a physical interface directly connected to another interface on the same chassis.
質問 # 27
Which of the following statements about using BFD with BGP is FALSE?
- A. Using BFD can speed up the BGP advertisement interval.
- B. It can help rapidly detect link failures.
- C. BGP is notified if several BFD control packets are missed.
- D. The BFD endpoints agree on the send/receive rate of control packets.
正解：A
解説：
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.
質問 # 28
Which of the following statements about the MAC table shown in the exhibit output is FALSE?
- A. Mac-duplication detection is enabled in mac-vrf-1.
- B. [interface ethernet-1/10 is configured with the MAC address 00:25:BA:00:00:10.
- C. The MAC address 00:25: BA:00:00:10 is learnt on more than one interface.
- D. The MAC re-learning rate has exceeded the threshold within the specified time frame.
正解：C
解説：
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.
質問 # 29
Which of the following statements about multi-homing in EVPN is FALSE?
- A. Type 1 Ethernet Auto-Discovery (A-D) EVPN route is used to support EVPN multi-homing.
- B. The ES identifier (ESI) uniquely identifies an ES and it is locally significant for a particular leaf.
- C. Type 4 Ethernet Segment (ES) EVPN route is used for designated forwarder (DF) election for an ES.
- D. The Ethernet Segment (ES) identifies a set of links that connects a host to one or more leafs.
正解：B
解説：
The Ethernet Segment Identifier (ESI) uniquely identifies an Ethernet Segment (ES) globally across the EVPN domain, not just locally for a particular leaf.
質問 # 30
Which of the following statements about next-hop groups is TRUE?
- A. The next-hop for a next-hop-group must be a local IP address.
- B. Multiple static routes can use the same next-hop-group.
- C. CMP destination unreachable message is always sent when blackhole is specified in the next-hop-group.
- D. A next-hop-group can only specify one next-hop for forwarding
正解：B
解説：
Multiple static routes can share the same next-hop group, enabling efficient reuse of next-hop definitions for load balancing or redundancy.
質問 # 31
Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?
- A. It supports both IPv4 and IPv6.
- B. It is more efficient than link-state protocols like IS-IS and OSPF.
- C. BGP neighbors automatically discover each other.
- D. It is a well understood and mature routing protocol.
正解：B
解説：
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.
