New Questions 9

When a router makes a routing decision for a packet that is received from one network and destined to another, which portion of the packet does if replace?

A. Layer 2 frame header and trailer

B. Layer 3 IP address

C. Layer 5 session

D. Layer 4 protocol

Answer: A

Explanation:

Router Switching Function (1.2.1.1)

A primary function of a router is to forward packets toward their destination. This is accomplished by using a switching function, which is the process used by a router to accept a packet on one interface and forward it out of another interface. A key responsibility of the switching function is to encapsulate packets in the appropriate data link frame type for the outgoing data link.

NOTE

In this context, the term u201cswitchingu201d literally means moving packets from source to destination and should not be confused with the function of a Layer 2 switch.

After the router has determined the exit interface using the path determination function, the router must encapsulate the packet into the data link frame of the outgoing interface.

What does a router do with a packet received from one network and destined for another network? The router performs the following three major steps:

u2711 Step 1.De-encapsulates the Layer 3 packet by removing the Layer 2 frame header

and trailer.

u2711 Step 2.Examines the destination IP address of the IP packet to find the best path in the routing table.

u2711 Step 3.If the router finds a path to the destination, it encapsulates the Layer 3 packet into a new Layer 2 frame and forwards the frame out the exit interface.

B. satellite Internet

C. municipal Wi-Fi

Answer: A,B,C


New Questions 11

Refer to the exhibit.

You have discovered that computers on the 192 168 10 0/24 network can ping their default gateway, but they cannot connect to any resources on a remote network Which reason for the problem is most likely true?

A. The 192.168.12 0/24 network is missing from OSPF

B. The OSPF process ID is incorrect

C. The OSPF area number is incorrect.

D. An ARP table entry is missing for 192.168.10.0.

E. A VLAN number is incorrect for 192.168.10.0.

Answer: A


New Questions 12

Refer to the exhibit. Which two statements are true about the loopback address that is configured on RouterB? (Choose two.)

A. It ensures that data will be forwarded by RouterB.

B. It provides stability for the OSPF process on RouterB.

C. It specifies that the router ID for RouterB should be 10.0.0.1.

D. It decreases the metric for routes that are advertised from RouterB.

E. It indicates that RouterB should be elected the DR for the LAN.

Answer: B,C

Explanation:

A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) -

The router-ID is chosen in the order below:

+ The highest IP address assigned to a loopback (logical) interface.+ If a loopback interface is not defined, the highest IP address of all active routeru2019s physical interfaces will be chosen.

-> The loopback interface will be chosen as the router ID of RouterB u2013


New Questions 13

Which symptom most commonly indicates that two connecting interfaces are configured with a duplex mismatch?

A. the spanning-tree process shutting down

B. collisions on the interface

C. an interface with a down/down status

D. an interface with an up/down status

Answer: B

D. ESRP

Answer: A


New Questions 15

Which three statements about link-state routing are true? (Choose three.)

A. Routes are updated when a change in topology occurs.

B. Updates are sent to a multicast address by default.

C. OSPF is a link-state protocol.

D. Updates are sent to a broadcast address.

E. RIP is a link-state protocol.

F. It uses split horizon.

Answer: A,B,C
