Question 1

To deploy multicast video applications on your private internal network, you need to use private multicast IP addresses on the network. Which range of IP addresses can be used?

Accepted Answer

The range 239.0.0.0 to 239.255.255.255 is designated for private multicast addresses, also known as administratively scoped addresses, which are used within private networks.

Question 2

Question 4

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

Accepted Answer

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

Question 5

Why does RSTP achieve faster convergence than STP?

Accepted Answer

RSTP (Rapid Spanning Tree Protocol) achieves faster convergence than STP (Spanning Tree Protocol) because it does not rely on the timer-based mechanism used by STP. Instead, RSTP uses a handshake mechanism to quickly transition ports to forwarding state, allowing for faster network topology changes.

Question 6

OSPFv3 and IS-IS are both running on a router, and the OSPFv3 routes need to be imported into IS-IS. Given this information, which of the following import configurations must be made?

Accepted Answer

Question 7

If multiple candidate RPs are configured in a multicast domain, which of the following parameters need to be compared when electing the RP of the group from multiple candidate RPs?

Accepted Answer

The IP address of the C-RP interface is used as a tie-breaker when multiple candidate RPs have the same priority and group range mask length.

Question 11

As shown in the figure, the IS-IS neighbor relationship has just been established between R1 and R2. Which of the following statements regarding the LSDB synchronization between R1 and R2 is true?

Accepted Answer

The answer of As shown in the figure, the IS-IS...

Question 12

Synchronization between LDP and IGP suppresses reachable IGP route advertisement to implement network convergence and ensure LDP and IGP are along the same path. This minimizes traffic loss and improves network reliability.

Accepted Answer

Synchronization between LDP (Label Distribution Protocol) and IGP (Interior Gateway Protocol) ensures that LDP labels are distributed only when the IGP routes are fully converged, preventing traffic from being sent over paths that are not yet ready, thus minimizing traffic loss and improving network reliability.

Question 13

Which of the following statements regarding 802.1X authentication, RADIUS authentication, and HWTACACS authentication are true?

Accepted Answer

The answer of Which of the following statements regarding 802.1X...

Question 14

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

Accepted Answer

D  A route-policy must have at least one node with a permit action to allow routes. The entry "permit :: 0 less-equal 128" allows all IPv6 routes as it matches any IPv6 address with a prefix length from 0 to 128.

Question 15

A router is connected to two EBGP peers through two parallel serial cables. What method can be used to achieve bidirectional load balancing between the EBGP peers?

Accepted Answer

Establishing an EBGP peer relationship through loopback interfaces and configuring them as update sources, along with importing equal-cost routes and using the ebgp-max-hop and next-hop-local commands, allows for bidirectional load balancing.
