Demo Questions

Question 1
What role does SRv6 play in Service Function Chaining (SFC)?
  1. It bypasses all service nodes automatically
  2. It statically fixes packet forwarding
  3. It encodes service paths directly in the packet header
  4. It encrypts Ethernet headers end-to-end
Correct answer: C
Question 2
Which metric is essential in Automatic O&M for proactive performance monitoring?
  1. VLAN tag length
  2. CPU utilization trends
  3. MPLS TE tunnel name length
  4. Manual SNMP trap polling
Correct answer: B
Question 3
Where is the fronthaul segment located in a 5G transport network architecture?
  1. Between CU and DU
  2. Between RRU and DU
  3. Between core network and aggregation
  4. Between PE and CE routers
Correct answer: B
Question 4
What defines the main feature of HQoS compared to traditional QoS?
  1. HQoS manages service control using VLAN stacking
  2. HQoS classifies, queues, and schedules traffic at multiple hierarchy levels
  3. HQoS relies on only a single queue per service
  4. HQoS disables traffic policing by default
Correct answer: B
Question 5
A carrier must guarantee differentiated service quality between mobile broadband, IoT services, and enterprise leased lines over a shared network.
Which three HQoS configurations are critical for this design? (Choose THREE.)
  1. Separate queue sets for different service classes
  2. Weighted fair queuing (WFQ) at user and service levels
  3. Disable all policing mechanisms to prioritize mobile traffic
  4. Enforce per-service traffic shaping policies
  5. Static MAC learning optimization
Correct answer: A, B, D
Question 6
True or False: IS-IS authentication can be applied separately at the LSP and Hello PDU levels.
  1. True
  2. False
Correct answer: A
Question 7
True or False: 5G mobile backhaul designs must ensure strict latency and jitter requirements even under link failures.
  1. True
  2. False
Correct answer: A
Question 8
An operator is migrating services to dual-stack IPv4/IPv6 over MPLS.
Which three MP-BGP features are crucial for successful deployment? (Choose THREE.)
  1. VPNv6 route propagation
  2. IPv6 link-local address resolution
  3. Separate address family RIBs
  4. IPv6 SID assignment
  5. Dual-Stack IPv6 forwarding
Correct answer: A, C, E
Question 9
Which two solutions help build SR-MPLS TE tunnels across different ASes? (Choose TWO.)
  1. SR-TE Policy stitching
  2. BGP-LS route distribution
  3. VLAN segmentation
  4. IPv6 static routing
Correct answer: A, B
Question 10
How does QoS enhance 5G backhaul performance?
  1. By statically configuring BFD timers
  2. By dynamically optimizing MPLS VPNv4 routes
  3. By prioritizing critical services like voice over less critical services
  4. By enforcing strict PIM-SM group memberships
Correct answer: C
Question 11
A service provider is migrating from traditional PIM-based multicast VPNs to a BIERv6-based architecture to improve efficiency.
Which three actions are critical for the migration? (Choose THREE.)
  1. Enable BIER support on core routers
  2. Configure BitString forwarding for multicast groups
  3. Replace MPLS SR-TE tunnels with RSVP-TE
  4. Enable BIER domain-specific BGP extensions
  5. Rebuild multicast trees using static configurations
Correct answer: A, B, D
