Cisco ENCOR Cisco ENCOR 350-401 Trivia 2 — Questions and Answers
Question 1: Which Cisco technology uses a control plane that is physically separated from the data plane across the entire network fabric?
- MPLS
- SD-Access (Correct answer)
- VTP
- EIGRP
Correct answer: SD-Access
SD-Access separates the control plane from the data plane using a centralized controller (Cisco DNA Center) to manage the entire fabric.
Question 2: In OSPF, what is the default hello interval on a broadcast network?
- 5 seconds
- 10 seconds (Correct answer)
- 30 seconds
- 40 seconds
Correct answer: 10 seconds
OSPF uses a default hello interval of 10 seconds on broadcast and point-to-point networks.
Question 3: Which QoS model uses per-flow state information and RSVP signaling to guarantee bandwidth?
- Best Effort
- DiffServ
- IntServ (Correct answer)
- MPLS TE
Correct answer: IntServ
Integrated Services (IntServ) uses RSVP to signal and reserve per-flow resources end-to-end across the network.
Question 4: What is the purpose of the Cisco TrustSec Security Group Tag (SGT)?
- Encrypt traffic between endpoints
- Classify traffic for policy enforcement regardless of IP (Correct answer)
- Assign VLAN membership dynamically
- Replace 802.1X authentication
Correct answer: Classify traffic for policy enforcement regardless of IP
SGTs classify network traffic at ingress and allow policy enforcement based on user/device identity rather than IP address.
Question 5: Which spanning tree port state forwards frames but does NOT learn MAC addresses?
- Blocking
- Listening (Correct answer)
- Learning
- Forwarding
Correct answer: Listening
In the Listening state, a port participates in spanning tree and can forward BPDUs, but it does not learn MAC addresses.
Question 6: In BGP, which attribute is used FIRST in the BGP path selection process?
- AS Path
- Local Preference
- Weight (Correct answer)
- MED
Correct answer: Weight
Cisco's BGP path selection first checks the Weight attribute, which is Cisco-proprietary and locally significant to the router.
Question 7: Which multicast protocol is used between a multicast router and directly connected hosts to manage group membership?
- PIM-SM
- IGMP (Correct answer)
- MSDP
- RSVP
Correct answer: IGMP
IGMP (Internet Group Management Protocol) is used by hosts to report multicast group membership to their directly connected routers.
