Question 232

The address resolution feature for NDP in the following description is incorrect?

When sending a neighbor request packet, the source addressóis set as the link-local address

of the local interface Two types of ICMPv6 messages,

are used in the address resolution process, neighbor request and neighbor advertisement Address resolution implements the ability to resolve from IPv6 addresses to link-layer addresses

When sending a neighbor request packet, the destination address must be the multicast address of the neighbor's requested node

Question 238

What's wrong about vrrp timers is ?

MASTER DOWN = (3*ADVER_ INTERVAL) + Skew_ time

Skew Time= (255-Priority)/255

Although the STP protocol can solve the loop problem, it affects the quality of user communication due to the slow convergence of the network topology. RSTP has made many improvements to STP, which of the following is not an improvement of RSTP to STP?

In addition to the 3 port states, RSTP vice adds 2 new port roles

Non-root switches running RSTP send configuration BPDUs at intervals specified by Hello Timer, a behavior that is entirely autonomous for each device

RSTP port state specification is divided according to whether the port forwards user traffic and learns the MAC address, reducing the original 5 port states to 3

If a port does not receive a configuration BPDU sent by the upstream device for 4 consecutive Hello Time, the device considers the negotiation with this neighbor to fail
