Question 581

(0)

Which of the following situations will occur after multicast load balance is configured? (Choose three.)

Question 582

(0)

ACL rules are matched based on the configured order only.

Question 583

(0)

Before establishing a network, we must create VLANs. The users that do not need to communicate with each other should be added to the same VLAN for isolation.

Question 584

(0)

A 32-bit MPLS header consists of a 20-bit label used for packet forwarding, a 3-bit EXP field that identifies the IP packet priority, a 1-bit bottom-of-stack flag that identifies the last label, and

Question 585

(0)

Which of the following statements regarding RPs are true? (Choose three.)

Question 586

(0)

BGP is an exterior gateway protocol which runs between ASs. It focuses on the control of route propagation and selection of optimal routes rather than discovery and calculation of routes.

Question 587

(0)

RTA is a source's DR and RTB is an RP. A multicast source sends multicast data to RTA but RTB cannot find any information about the multicast source (registered by using the PIM Register message). W

Question 588

(0)

Which of the following describes the relationship between BGP and AS?

Question 589

(0)

To which attribute type does the BGP AS-Path attribute belong?

Question 590

(0)

VLANs isolate broadcast domains, eliminates broadcast storms, and enhances information security.

Question 581

Which of the following situations will occur after multicast load balance is configured? (Choose three.)

If there are no equal-cost unicast routes, multicast load balance will fail to function.

If group address-based load splitting is used, balanced entry distribution over equal-cost routes cannot be ensured because of hash algorithm limitations.

Balanced entry distribution over equal-cost routes can be ensured as long as multicast load balance is configured.

In multicast load splitting, traffic may not be balanced among equal-cost routes. This is because multicast load balance is based on multicast entries but not based on multicast data packets.

A 32-bit MPLS header consists of a 20-bit label used for packet forwarding, a 3-bit EXP field that identifies the IP packet priority, a 1-bit bottom-of-stack flag that identifies the last label, and an 8- bit ITL field. Which statement about the ITL field is true?

It is used to prevent packet forwarding loops, similar to the TTL field in an IP header.

It is used for label management.

It specifies the upstream device in label distribution

It controls the LSR.

Question 585

Which of the following statements regarding RPs are true? (Choose three.)

Different group addresses on a PIM-SM network corresponds to different RPs.

An RP is the root of an RPT.

An RP is elected out of BSRs.

All routers on a PIM-SM network must automatically discover the location of RPs.

Question 587

RTA is a source's DR and RTB is an RP. A multicast source sends multicast data to RTA but RTB cannot find any information about the multicast source (registered by using the PIM Register message). Why? (Choose three.)

RTB has no unicast routes to RTA.

RTA fails to learn RP information.

RTA has no unicast routes to RTB.

The RP learned by RTA is not RTB.
