質問 # 46
Network administrators can run the clock timezone command to set the time zone of a device. If two network devices have different time zone settings, they cannot establish a neighbor relationship using a dynamic routing protocol.
Options:

A. FALSE
B. TRUE

正解：A

解説：
Comprehensive and Detailed In-Depth Explanation:
* The clock timezone command only affects the displayed time on the device and does not impact routing protocol operations.
* Dynamic routing protocols such as OSPF, IS-IS, BGP, and EIGRP rely on timers, authentication, and correct network configurations, but they do not require the same time zone settings.
* Potential issues with different time zones:# Log timestamps may be inconsistent, making troubleshooting harder.# Time-sensitive features like NTP synchronization might be affected.# But different time zones will not prevent dynamic routing neighbor relationships.

質問 # 49
On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?

A. If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3 because FRR is enabled on R1.
B. If the link between R2 and SI is disconnected, R1 recalculates the optimal path to R3 and performs path switching instantly.
C. If the link between R1 and SI is disconnected, Rl recalculates the optimal path to R3 and performs path switching instantly.
D. If the link between R1 and SI is disconnected and you check neighbor information on R1, the neighbor relationship between R1 and R2 will instantly display Down.

正解：C

質問 # 50

A. TRUE
B. FALSE

正解：A

質問 # 51
On a stable network that requires fast route convergence, you can change the value of the interval at which OSPF LSAs are updated to 0 so that topology or route changes can be immediately advertised on the network through LSAs, which speeds up route convergence.

A. TRUE
B. FALSE

正解：A

質問 # 52

B. True

正解：B

質問 # 53
In an MPLS network, SR running the DP protocol exchange LDP messages to realize functions such as neighbor discovery, session establishment and maintenance, and label management. In order to ensure the reliability of message delivery, all sending and receiving of LDP messages must be based on TCP connections.

A. FALSE
B. TRUE

正解：A

質問 # 57
The MPLS architecture consists of the control plane and forwarding plane, each of which contains multiple protocols and entries. Which of the following tables is used to forward MPLS labeled packets?
Options:

A. LFIB
B. LIB
C. FIB
D. RIB

正解：A

解説：
Comprehensive and Detailed In-Depth Explanation:
* MPLS packet forwarding is based on label information stored in the LFIB (Label Forwarding Information Base).
* The role of different tables in MPLS:# RIB (Routing Information Base): Stores routing information, but does not handle MPLS label forwarding.# LIB (Label Information Base): Stores label bindings but is used for control-plane operations.# FIB (Forwarding Information Base): Used for IP forwarding, not MPLS forwarding.# LFIB (Label Forwarding Information Base): The correct table, which maps incoming labels to outgoing labels (or actions like swap, push, pop) and is used for actual MPLS packet forwarding.
