NEW QUESTION # 239
In OSPF, an ABR translates all Type 7 LSAs in a Not-So-Stubby Area (NSSA) into Type 5 LSAs.
  • A. FALSE
  • B. TRUE
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
InOSPF, a Not-So-Stubby Area (NSSA) is a type of area that allows for the injection ofexternal routes(like a standard area) while maintaining some stub area characteristics.
Type 7 LSAs (NSSA External LSAs)are generated by ASBRs within an NSSA.
AnABRat the NSSA boundary translates theseType 7 LSAs into Type 5 LSAsto propagate them into the rest of the OSPF domain.
This translation is necessary becauseType 5 LSAsare the standard method for advertising external routes in OSPF.
Therefore, the statement isTRUE.

NEW QUESTION # 240
Refer to the following command output on the router R3. Which of the following statements are correct?
<R3> display interface Tunnel
Tunnel0/0/0 current state : UP
Line protocol current state : UP
Last line protocol up time : 15:21:26 UTC-08:00
Description: HUAWEI, AR Series, Tunnel0/0/0 Interface
Route Port, The Maximum Transmit Unit is 1500
Internet Address is 20.1.1.2/24
Encapsulation is TUNNEL, loopback not set
Tunnel source 10.0.3.3 (LoopBack0), destination 10.0.1.1
Tunnel protocol/transport GRE/IP, key disabled
keepalive disabled
Checksumming of packets disabled
  • A. The tunnel interface MTU is 1500 bytes.
  • B. The tunnel destination IP address is 10.0.1.1.
  • C. The tunnel interface IP address is 20.1.1.2/24.
  • D. The tunnel source IP address is 10.0.1.1.
Answer: A,B,C
Explanation:
From the output:
Tunnel destination IP address: Clearly shown as destination 10.0.1.1 ## Tunnel interface MTU: Shown as The Maximum Transmit Unit is 1500 ## Tunnel interface IP: Shown as Internet Address is 20.1.1.2/24 ## Tunnel source: Tunnel source 10.0.3.3 (LoopBack0) # Not 10.0.1.1 ## Therefore:
A- Correct
B- Correct
C- Correct
D- Incorrect (confuses destination as source)
Correct answers: A, B, C

NEW QUESTION # 241

Answer: D

NEW QUESTION # 242
BGP Link State (BGP-LS) introduces a new NLRI into BGP. The NLRI carries link, node, topology prefix, and other information, and is also referred to as the link state NLRI.
  • A. FALSE
  • B. TRUE
Answer: B
Explanation:
Understanding BGP Link State (BGP-LS)
# What is BGP-LS?
* BGP-LS (BGP Link-State) is an extension of BGP that allows routers to exchange network topology information via Link-State NLRI.
* Helps SDN controllers and path computation elements (PCEs) make intelligent routing decisions.
# What Does BGP-LS Advertise?# Node Information - Router IDs, Loopbacks# Link Information - Bandwidth, Delay, Cost# Prefix Information - Network Subnets# Topology Information - Full network graph Why is the Answer TRUE?
# BGP-LS introduces a new NLRI format for advertising link-state information.# NLRI (Network Layer Reachability Information) is used to distribute topology data to SDN controllers.# It improves path optimization by enabling centralized traffic engineering decisions.
Real-World Application:
* SDN-Based Traffic Engineering: Used in Segment Routing (SR) networks for centralized path selection.
* MPLS TE (Traffic Engineering): Optimizes network paths dynamically based on real-time link-state data.
