NO.264 IPSG can configure static binding table or use DHCP-snooping to form a binding table.

True

False

NO.265 Which of the following descriptions are wrong about BGP load sharing? (Multiple Choice)

IBGP routes and EBGP routes arriving at the same destination on the public network can form load balancing.

If BGP load balancing is implemented, the local device needs to be configured with the peer next-hop-local command to change the next hop address to its own address when advertise router to the IBGP peer group.

The destination network segment is the same, and BGP routes with different sources can form load sharing.

The AS_Path attribute of the equal-cost route that forms load sharing must be different.

NO.266 ICMPv6 has two types: Error Messages and Information Messages.

TRUE

FALSE

NO.267 When judging LSA is old or new, will use the serial number of the reference models and age parameters, which the following statements about the two parameters are correct? (Multiple choice)

When the router receives two LSAs with the same sequence number and the same checksum, the smaller the age, the better

When the router receives an LSA, the age is set to 3600S, indicating that this LSA is unavailable

If the sequence number of the LSA reaches the end value Ox7FFFFFFF, the current router advertises the LSA whose age is 3600S

Both the serial number and age parameters can determine the old and new LSA, the router will give priority to the sequence to participate in the teaching, the larger the better

True

False

NO.269 The correct description in the following of BGP loop protection is: (Multiple Choice)

Any routing information from IBGP peers will be advertised to other IBGP peers

Non-RR BGP routers will not announce any update information from IBGP peers to other IBGP peers

DBGP routers will not announce any updates from EBGP peers to their EBGP peers

The interval for sending Level-2 hello packets on this interface is 5s

The interval for sending Level-2 CSNP packets of this interface is 5s

NO.271 VRRP priority cannot be set to 0, so the device which send VRRP packets of priority 0 will stop adding VRRP backup group, and inform the backup device immediately become a Master device, without waiting for Master_Down_Interval timer expires.

True

False

You can prevent the Eth-Trunk interface from frequently flapping due to physical link reasons. Interface eth-trunk 1 Lacp preempt enable Lacp preempt delay delay-time

You can configure the source IP address for load balancing in the enabled link aggregation group by using the following command: Interface eth-trunk 1 Load-balance src-dst-ip

You can remove a member interface in an enabled link aggregation group by using the following command: Interface Gigabitethemnet0/0/0 Debug Interface Gigabitethernet0/0/1 Undo eth-trunk 1 Interface Gigabitetheret0/0/ Undo shutdown

You can add member interfaces to the link aggregation group enabled by the following command: Interface Gigabitethernet0/0/1 Debug Interface Gigabitethernet0/0/1 Trunkport Gigabitethernet0/0/ Interface Gigabitethernet0/0/1 Undo shutdown

NO.273 Which of the following description about the VRRP timer is wrong? (Multiple choice)

MASTER DOWN=(3* ADVER_INTERVAL)+Skew_time

Skew Time=(255- Priority)/255

By default, the time period for VRRP notification messages is 2 seconds

By default, the VRRP preemption delay is 1 second

NO.274 IPv6 introduces Solicited-Node address, which of the following description about the address is correct?

This is a specific address, which is used to resolve MAC addresses in ARPV6.

The Solicited-Node address on the router interface is automatically generated, and there can be multiple.

If the Solicited-Node address is not configured , the router will automatically generate one on each interface.

IPv6 introduces Solicited-Node address to support IPV6 multicast.

NO.275 Which TLV does IS-IS use to describe the IP Interface Address?

128

131

132

129

NO.276 Which of the following description of the 802.1s deployment features is correct?

Multiple bridges share a spanning tree instance

All VLANs share a spanning tree instance

Each VLAN shares a spanning tree instance

Multiple VLANs share a spanning tree instance

NO.277 An existing BGP router HW1 is configured with both an IBGP neighbor and an EBGP neighbor.
Which of the following descriptions are correct about IBGP neighbors and EBGP neighbors? (Multiple Choice)

The router will send BGP updates learned from its IBGP neighbors to its own other IBGP neighbors and EBGP neighbors.

The router will send BGP updates learned from its EBGP neighbors to its own other IBGP neighbors and EBGP neighbors.

IBGP neighbors must be directly connected. Otherwise, IBGP-Multi-hop must be configured

EBGP neighbors must be directly connected. Otherwise, EBGP-Multi-hop must be configured

IBGP neighbors can establish neighbor relationships through loopback interfaces.

EBGP neighbors must establish neighbor relationships through directly connected physical interface addresses.

NO.278 Regarding the introduction of routes, which of the following description is wrong?

bgp supports both import and network when generating routes. Network mode is more accurate.

By default, the default metric of the external route redistributed by OSPF is 1, and the imported external route type is Type2.

After ISIS’s level-2 network route is imported to the level-1 network, if the import policy is not manually configured, a routing loop is formed.

Introducing IBGP routes in OSPF may cause routing loops.

NO.279 You want to set the DSCP value of VoIP traffic in HW network equipment to EF.
