Which of the following statements about BPDUs in STP is false?
BPDUs are classified into configuration BPDUs and TCN BPDUs.
TCN BPDUs are triggered only when the network topology changes
When the network topology becomes stable, all switches proactively send configuration BPDUs.
configuration BPDU contains parameters such as the bridge ID. path cost, and port ID
In which of the following modes are DHCP Discover messages sent?
Anycast
Broadcast
Unicast
Multicast
The following shows partial OSPF neighbor information for a specific router: OSPF Process 1 with Router ID 10.1.1.3 Neighbors Area 0.0.0.0 interface neighbors Router ID: 10.1.1.1 Address: 10.1.1.1 State: Full Mode:Nbr is Slave Priority: 1 DR: 10.1.1.5 BDR: 10.1.1.1 MTU: 0 Dead timer due in 35 sec Retrans timer interval: 5 Neighbor is up for 00:02:01 Authentication Sequence: [ 0 ] Which of the following statements is false?
The router is a DR-other router.
The preceding information is about the neighbor relationship of the router and BDR router.
The router ID of the OSPF process on the router is 10.1.1.3.
The router is the slave router in the master-slave relationship.
An IPv6 address is 128 bits long. Typically, an IPv6 address is represented by eight groups of 16-bit hexadecimal values separated by colons (:). Which of the following statements about IPv6 addresses is false?
The IPv6 address with the prefix FE80::/10 is a link-local address (LLA).
Each IPv6 interface must have a unique local address (ULA).
global unicast address (GUA) is globally unique.
There may be ULA conflicts in a global scope.
As shown in the following networking, the interfaces connecting RI, R2, R3, and R4 are running OSPF, and are all in area O. On RI, a static route to the network segment 10.1.34.0/24 is configured using the ip route-static 10.1.34.0 24 10.1.13.32 command. Which of the following statements is true?
The routing table of RI contains both the static route and OSPF route to the network segment 10.1.34.0/24.
The routing table of RI contains only the OSPF route to the network segment 10.1.34.0/24, and the next hop of the route is 10.1.13.32.
The routing table of RI contains only the static route to the network segment 10.1.34.0/24.
The routing table of RI contains the OSPF route to the network segment 10.1.34.0/24, and the next hop of the route is 10.1.12.21.
The ping and tracert commands are used to check the network status. Which of the following statements about the ping and tracert commands is false?
The source IP address of packets to be sent can be specified in the tracert command.
The tracert command can be used to check the gateways that packets pass through before reaching the destination.
The ping command can be used to check connectivity to a destination address.
The ping -s source-ip-address destination-ip-address command is used to specify the source and destination IP addresses of ICMP Echo Request packets.
SNMP is used to manage network devices. Refer to the following SNMP configuration on a Huawei device. Which of the following statements is false? [~HUAWEI] display current-configuration I include snmp snmp-agent snmp-agent local-engineid 800007DB03001974593301 snmp-agent sys-info version v3 snmp-agent mib-view included iso-view iso snmp-agent group v3 v3group privacy read-view iso-view write-view iso-view notify-view iso-view snmp-agent usm-user v3 v3user snmp-agent usm-user v3 v3user group v3group snmp-agent usm-user v3 v3user authentication-mode sha cipher snmp-agent usm-user v3 v3user privacy-mode aes256 cipher
The encryption mode of the v3user user is SHA.
The v3user user can access nodes in the subtree with iso as the root node.
SNMP packets will be encrypted using AES256.
SNMPv3 is configured.
Mastering the basic operations of the file system is crucial for network engineers to efficiently manage the configuration files and VRP system files of devices. Which of the following statements is true about these files?
configuration file stores configuration commands. The common file name extension is .cc.
patch file is a type of software compatible with the system software. The common file name extension is .zip.
PAF file effectively controls product features and resources. The common file name extension is .bin.
System software is mandatory for device startup and running. The common file name extension is .cfg.
Network Address Translation (NAT) translates the IP address in an IP packet header into another IP address. Which of the following is not an advantage of NAT?
Implementing accurate identification and control of packet flows on networks to control network access behavior, prevent network attacks, and improve network bandwidth efficiency
Effectively preventing attacks from external networks and greatly improving network security
Allowing the access of intranet hosts to external networks and the access of external hosts to intranets. and enabling communication between intranets and external networks
Alleviating the exhaustion of IP addresses
A WLAN is constructed using wireless technologies. Which of the following statements about the WLAN networking is false?
basic service set (BSS) indicates an area covered by an AP.
virtual access point (VAP) is a service entity virtualized on an AP. All VAPS virtualized on the same AP has the same BSSID.
The service set identifier (SSID) identifies a wireless network and is represented using a character string.
The basic service set identifier (BSSID) identifies a wireless network and is represented using the MAC address of an AP
Which of the following statements is true about APs in WLAN networking?
Typically, APs use POE power to facilitate deployment
Fit APs can independently implement functions such as wireless user access, service data encryption, and service data packet forwarding.
Fat APs need to work with an AC and are managed and configured by the AC in a unified manner
An AC must be deployed in WLAN networks.
