A. 4

B. 8

C. 6

D. 2

Correct Answer: C

Question 2

What can be used to encrypt data in flight between untrusted locations?

A. MACSec

B. MD5 encryption

C. OSPF authentication

D. GRE tunnels

Correct Answer: A

Question 3

2-Tier L2 Design
* 6400 100G Core Switches
* 8320 48-P 10G RJ45 Access Switches
* 40G DAC connections between Core and AccessCore Switches = VSX Pairs of 6400 switches (each with 2 x 12-port QSFP28 100G modules) Each pair uses:
* 2 x 1M 100G DAC for ISL
* 1 x 1M 100G DAC for Keepalive
* 2 x 5M 40G DAC to each access switch
Each Spine switch has 5 x 100G interfaces available.
This solution could scale to a maximum of:

A. 12 total racks using same subscription rates

B. 10 total racks using same subscription rates

C. 7 total racks using same subscription rates

D. 15 total racks using same subscription rates

Correct Answer: D

Question 4

Which switch model is able to perform microsegmentation?

A. CX 8360

B. CX 10000

C. CX 8400

D. CX 8325

E. CX 6400

Correct Answer: B

Question 5

You want to configure your border leaf switches to leak routes between an overlay VRF named "dc1" and a VRF named "campus," which connects to the campus core. You also want to leak routes between an overlay VRF named "dc2" and the campus VRF. "dc1" should not be able to communicate with "dc2." Which is a valid design for the VRFs' IPv4 route-targets?

A. vrf dc1, import = 1:1, export = 1:1; vrf dc2, import = 1:1, export = 1:1; vrf campus, import = 1:1, export
= 1:99

B. vrf dc1, import = 1:1, export = 1:1; vrf dc2, import = 1:2, export = 1:2; vrf campus, import = 1:1, 1:2, 1:
99, export = 1:99

C. vrf dc1, import = 1:99, export = 1:1; vrf dc2, import = 1:99, export = 1:2; vrf campus, import = 1:1, 1:2 export = 1:99

D. vrf dc1, import = 1:1, export = 1:99; vrf dc2, import = 1:2, export = 1:99; vrf campus, import = 1:99, export = 1:1, 1:2

Correct Answer: C

Question 6

Mention two advantages of the ToR switches in Data Center Design

A. Better issue isolation

B. Possibly less expensive

C. Less unused ports on the switches

D. Less cable sprawl

Correct Answer: A,D

Question 7

Mention two disadvantages of the End-of-Row or Middle-of-Row switches in Data Center design

A. More equipment

B. Longer, more complex cabling within the row

C. Higher latency for rack-to-rack traffic within the row

D. Lower port density and less scalable

Correct Answer: B,D

Question 8

You want to implement distributed firewall policies that micro-segment VM-to-VM traffic, including within the VLAN and same host. The VMs should be able to send traffic on permitted TCP ports, but other traffic should be dropped (hosts are isolated). What are two requirements? (Select two.)

A. VLAN 10 is converted to a PVLAN on the switch and VMware hosts. The VMs are placed in an isolated VLAN

B. The VMware host is configured to implement a local firewall

C. SVI 10 on the switch has IP local ARP proxy enabled on it

D. VLAN 10 is converted to a PVLAN on the switch only. The VMs are placed in an isolatedVLAN

Correct Answer: A,C

Question 9

You are planning a leaf and spine topology for a data center. The campus is in a different building; the customer wants to connect the campus network directly to the data center network. To which data center switch or switches do you connect the campus core switches?

A. To two L2 edge switches, which are dedicated to connecting the spine and leaf topology to external networks

B. To two L3 edge switches, which are dedicated to connecting the spine and leaf topology to external networks

C. To two border leaf switches, which are dedicated to connecting the spine and leaf topology to external networks

D. To two service leaf switches, which are dedicated to connecting the spine and leaf topology to external networks

Correct Answer: C

Question 10
