What are the two main differences between TCAM and CAM?

Multiple Choice

In which two ways does TCAM differ from CAM? (Choose two.)

CAM is used to make Layer 2 forwarding decisions, and TCAM is used for Layer 3 address lookups.

CAM is used by routers for IP address lookups, and TCAM is used to make Layer 2 forwarding decisions.

CAM is used for software switching mechanisms, and TCAM is used for hardware switching mechanisms.

The MAC address table is contained in TCAM, and ACL and QoS information is stored in CAM.

What are the distinctions between a RIB and a FIB in networking?

Single Choice

What is the difference between a RIB and a FIB?

The FIB is populated based on RIB content.

The RIB maintains a mirror image of the FIB.

The RIB is used to make IP source prefix-based switching decisions.

The FIB is where all IP routing information is stored.

What is the significance of a local router showing an EBGP neighbor in the Active state?

Single Choice

A local router shows an EBGP neighbor in the Active state.

Which statement is true about the local router?

The local router is attempting to open a TCP session with the neighboring router.

The local router is receiving prefixes from the neighboring router and adding them in RIB-IN.

The local router has active prefixes in the forwarding table from the neighboring router.

The local router has BGP passive mode configured for the neighboring router.

What is the result of the CoPP configuration when the show command is entered?

Single Choice

Refer to the exhibit. An engineer configures CoPP and enters the show command to verify the implementation. What is the result of the configuration?

If traffic exceeds the specified rate, it will be transmitted and remarked.

All traffic will be policed based on access-list 120.

Class-default traffic will be dropped.

ICMP will be denied based on this configuration.

What state will the tunnel endpoint on RouterB most likely enter after attempting to bring up the GRE tunnel?

Single Choice

A GRE tunnel is configured between RouterB and RouterC. The GRE tunnel sources on each router are loopback interface IP addresses. The GRE tunnel destinations on each router are publicly routable IP addresses and are accessible by each tunnel source router.

After you attempt to bring up the tunnel, which of the following states will the tunnel endpoint on RouterB most likely enter? (Select the best answer.)

Administratively down/down

Down/up

Reset/down

Up/down

Up/up

Infrastructure Network Assurance

Correct Answer:

Up/up

Explanation:

Most likely, the tunnel endpoint on RouterB will enter the Up/up state in this scenario. GRE tunnels can use loopback interfaces as source interfaces. In addition, the destination IP addresses in this scenario are publicly routable and accessible by the sources. Interface states and line protocol states are often presented as a single connection state separated by a slash. The state preceding the slash represents the interface state. The state succeeding the slash represents the line protocol state. In order for the line protocol state to be up, the interface state must also be up.
A GRE tunnel can exist in one of the following four states:
- Administratively down/down
- Reset/down
- Up/down
- Up/up
A tunnel in the Administratively down/down state has been configured with the shutdown command. By default, a tunnel interface automatically transitions to the upstate when it is created. Therefore, it is not normally necessary to issue the no shutdowncommand to bring a tunnel interface up unless you have previously issued the shutdown command.
A tunnel in the Reset/down state is typically transiting through that state because a software interface reset has occurred. Software resets can happen if the tunnel is misconfigured. For example, a software reset might occur if a tunnel interface has been configured to use its own IP address as a next hop.
A tunnel in the Up/down state indicates that the tunnel interface is configured but something is interfering with the line protocol. This state commonly occurs when the tunnel interface is configured to use an incorrect destination address or when the physical interface has no route to the tunnel s destination address. It can also occur if the tunnel destination address lies through the tunnel itself.
A tunnel in the Up/up state indicates that both the tunnel interface and the line protocol are up and functional. If something is preventing communication between endpoints on opposite ends of the tunnel and the tunnel is in the Up/up state on each end, you should continue troubleshooting beyond the tunnel configuration.
