Question 1

What protocol does OSPF run over?

ATCP

BHTTP

CUDP

DIP

Answer : D

OSPF does not use TCP or UDP because it has its own reliable transmission mechanisms.

OSPF packets are encapsulated directly in IP packets using protocol number 89.

TCP (A) is used for connection-oriented communication, but OSPF does not rely on it.

UDP (C) is used for connectionless communication, but OSPF does not use it.

HTTP (B) is an application-layer protocol and irrelevant here.

Thus, the correct answer is D (IP).

Question 2

How many bytes are there in a basic IPv6 header?

A40

B48

C32

D64

Answer : A

The basic IPv6 header has a fixed length of 40 bytes. Unlike IPv4, the IPv6 header is streamlined, omitting some fields (like header checksum) and standardizing the header size. This simplification reduces processing overhead, enhancing routing efficiency and scalability for modern networks.

Question 3

Refer to the display startup command output shown in the figure. Which of the following statements are true?

AThe current VRP configuration file is different from that used for next startup.

BThe current VRP configuration file is the same as that used for next startup.

CThe current VRP version file is different from that used for next startup.

DThe current VRP version file is the same as that used for next startup.

Answer : A

Comprehensive Explanation= The output shows that the current and next startup configurations are different. Specifically, the startup saved-configuration file is flash:/vrpcfg.zip, and the next startup saved-configuration file is flash:/backup.zip, indicating that changes have been made and the system will use a different configuration file at the next reboot

Question 4

Network Address and Port Translation (NAPT) allows multiple private IP addresses to be mapped to the same public IP address through different port numbers. Which of the following statements about port numbers in NAPT is true?

AOnly the port number range needs to be configured.

BThe mappings between port numbers and private IP addresses must be manually configured.

CAn ACL is required to allocate port numbers.

DNo port number needs to be configured.

Answer : A

In NAPT, port numbers are dynamically assigned as traffic flows through the router. The port number range is automatically selected, and manual configuration of each mapping is not required. NAPT dynamically uses different ports for mapping private IP addresses to a single public IP address.

Question 5

Which of the following methods is not used for logging in to the VRP system?

ATelnet

BNetstream

CWeb

DSSH

Answer : B

Comprehensive Explanation= Netstream is a protocol for flow-based network traffic analysis, not a method for logging into a VRP system. The valid methods for accessing the VRP system include Telnet, Web, and SSH, which are used for remote management and configuration of network devices

Question 6

The router ID of the OSPF process takes effect immediately after being changed.

ATRUE

BFALSE

Answer : B

Question 7

Which of the following methods is not supported by the Versatile Routing Platform (VRP) to configure a router?

AConfigure the router through FTP.

BConfigure the router through the mini USB port.

CConfigure the router through Telnet.

DConfigure the router through the console port.

Answer : A

The VRP platform does not support configuration through FTP. Configuration methods typically include using a console port, Telnet, or SSH, allowing for direct access to the device configuration. FTP is generally used for file transfer, not direct configuration, and therefore is not a supported method for configuring a router.
