Question 3

A customer plans to migrate a pair of Cisco switches to a pair of 10 Gb Dell N-Series switches as the new Layer 2 Data Center Core. Per the plan, the Cisco switches are to be connected to the configured Dell N-Series switches to provide a migration path.
The default gateway exists as another entity and will connect to N-Series switchports in access mode. All end-devices are dual-homed to both Cisco switches. One connection from each server is to be moved to switchports on the N-Series switches. The configuration of the N-Series switches is as follows:
* The N-Series switches will have MST turned on
* The switches will have several VLANs configured
* The N-Series switches will use MLAG
* The N-Series will use 802.3ad link aggregation, and will not actively negotiate a connection
* The customer has established that the power requirements have been met for the new N-Series switches
* The correct power-cabling, QSPF+ to 4xSPF+ breakout cables, QSPF+ to QSPF+ DACs, and Ethernet cables have shipped, with the switches.
* The breakout cables will be used on the 40 Gb ports of the N-Series switches, which will connect out to the 10 Gb ports on the Cisco switches. The customer has provided the following information about the Cisco switches:
* They use StackWise technology, and therefore are stacked
* The type of switches are Catalyst 3850s, with 48-port 10/100/1000 copper connections and 4x10 Gb SFP+ ports
* The Cisco stack currently uses Rapid-PVST, and all bridge-priorities are administratively set to make the CiscoStack the Root Bridge
* The 10 Gb ports are a part of a port-channel that will connect to the N-Series switch
* The version of firmware, also known as the iOS, is up to date before implementing the deployment and cutover plan.
Which two pieces of information are required to finalize the plan?

A. CST configuration for the root bridge of all VLANs on the N-Series switches.MST configuration of the N-Series.

B. Static routes that are required for redistribution into OSPF on the Dell switches.Spanning-tree priority values on the Cisco stack.

C. Information of the port-channel on the Cisco stack to the N-Series VLT pair.Requirement for "intf-type cr4 autoneg" applied on all 10 Gb ports on the N-Series switch pair.

D. MST configuration of the N-Series.Spanning-tree priority values on the Cisco stack.

Correct Answer: A,C

Question 4

The exhibit shows an IGMPv2 multocast network where "Rn" are routers configured with PIM and OSPF runs between the routers.
Which two actions should the router(s) take with the multicast message forwaded to them from the switch connected to the user's desktop?

A. Translate membership report forward PIM-Leave message.Create a (* ,G) entry in the forwarding table.

B. Create a (S, *) entry in the forwarding table.Translate membership report to PIM-Join message and send to PIM neighbor(s) towards the RP (R3 is RP).

C. Translate membership report forward PIM-Leave message.Create a (S, *) entry in the forwarding table.

D. Create a (* ,G) entry in the forwarding table.Translate membership report to PIM-Join message and send to PIM neighbor(s) towards the RP (R3 is RP)

Correct Answer: D

Question 5

Refer to the exhibits of the S-Series switch.
A networking engineer is unable to pass traffic across interface port 13 and 43 for Dell1 and Dell2 S-Series switches, respectively.
Based on the exhibit, what is the problem with the configuration for the switches?

A. Port 43 needs to be tagged to pass traffic.

B. 802.1 w protocol needs to be disabled for both ports.

C. There is a native VLAN mismatch.

D. Port 13 needs to be tagged to pass traffic.

Correct Answer: C

Question 6

The network engineer powers on a new S-Series switch. None of the devices connected to this new switch are responding to pings.
Which two conditions should the network engineer verify? (Choose two.)

A. an ARP table is configured

B. the switch has a default Gateway

C. OSPF is enabled

D. ports are in switchport mode

E. ports are not shut down

Correct Answer: A,E

Question 7

Refer to the exhibits.
A network engineer has worked with PC support to install a new PC. After correctly configuring the PC's interfaces with valid IP addresses, the PC is not able to ping other devices on the 192.168.13.0/24 network.
The output from the PC after executing the command ipconfig /all is below:
The network engineer executes the command show mac address-table on the N-series switch to which the PC is connected.
The output of the show mac address-table command is below.
What are two reasons that the PC is unable to ping other devices? (Choose two.)

A. The default gateway needs to be configured for the network 192.168.13.0/24 to ping devices on the
192.168.13.0/24 network.

B. The port on the N-Series switch that the PC is connected to is shut down.

C. The switch is not registering MAC addresses in the MAC address table and needs to be reset.

D. The ARP table is corrupt on the PC and is not allowing the PC to register its MAC address with the switch.

E. The switch has not seen traffic from the PC and does not have an entry in the mac address table for the PC.

Correct Answer: D,E

Question 8

Refer to the exhibit.
A customer has a C-Series chassis using a 48-port PoE+ line card. A workstation connected to Gi 0/47 passes traffic as expected. When the customer connects a PoE phone to the interface, the phone does NOT power up.

A. console(conf-if-gi-0/47)#power inline auto

B. console(conf-if-gi-0/47)#auto power inline

C. console(conf-if-gi-0/47)#power inline on

A. Communication error

B. Incorrect Port-Channel numbering

C. Physical interfaces are shutdown
