Question 202

Inter-device link aggregation implements reliable transmission of data traffic and mutual backup for stack member switches. However, the bandwidth of stack cables between stacked devices is limited. Which of the following methods can be used to improve forwarding efficiency?

Configure the system MAC address switchover for the stack

Use a stack card to connect the devices to be stacked

Enable the function of preferentially forwarding local traffic

Enable multi-active detection (MAD) for the stack

Question 203

Why does RSTP achieve faster convergence than STP?

RSTP convergence is not based on the timer mechanism

RSTP has a smaller cost value

RSTP has additional port states

RSTP has a smaller timer value

In 802.1D, the bridge only forwards the BPDUs received from the root bridge

In 802.1w, the bridge only forwards the BPDUs received from the root bridge

In 802.1D, the bridge does not forward BPDUs

In 802.1w, the bridge does not forward BPDUs

Question 205

Two routers are connected through serial interfaces, but they cannot ping each other. The following information is displayed when you check the status of the connected interfaces:

Given this information, why are the two routers unable to ping each other?

The subnet masks of the two interfaces do not match

The IP addresses of the two interfaces are not on the same network segment

The link layer protocols of the two interfaces are inconsistent

The link bandwidth is insufficient

Question 206

Which of the following statements regarding BGP route filtering is false?

The relationship between the nodes of a route-policy is "OR." That is, a route matches the routing policy as long as it is allowed by one node.

On the same node of a routing policy, the relationship among multiple if-match clauses for different attributes is "OR."

After a route from a BGP peer is received and a routing policy is executed to filter out unnecessary BGP routes, these routes will not be added to the localBGP routing table.

When a routing policy is configured for locally advertised routes, this policy takes effect before the routes are added to the BGP routing table.

Question 207

Which of the following statements regarding route-policies are true?

If more than one node is defined in a route-policy, the matching mode of at least one node must be permit

An advanced ACL can be used in a route-policy to filter routes

A route-policy can filter only default routes

If the entry permit :: 0 less-equal 128 is defined, all IPv6 routes are permitted

Question 208

Which of the following statements regarding BGP route reflectors (RRs) are true?

If no RR is available, IBGP peers must be fully meshed. If an RR is available, IBGP peers do not need to be fully meshed

An RR can advertise routes learned from a client to the other clients and non-clients

An RR can advertise routes learned from IBGP peers to all clients and non-clients

An RR can advertise routes learned from non-clients to all clients
