You are designing a Data Center with Spine Leaf architecture. Spine Switches are 8400 with 12 QSFP28 ports (F-B airflow) and leaf switches are 8360 switches stacked with VSX in each rack.
The Customer sent you the following Specifications Each Spine Switch uses:
• 1 x 100G QSFP28 5M DACs to each Leaf switch Each Leaf Switch uses:
• 1 x 100G QSFP28 5M DACs to each Spine switch
• 2 x 100G 1M DAC for ISL
• 1 x 25G SFP28 DAC for Keep alive
What is the scalability in this design?
- A . Solution can scale to 12 total racks using the same subscription rates.
- B . Solution can scale to 24 total racks using the same subscription rates.
- C . Solution can scale to 36 total racks using the same subscription rates.
- D . Solution can scale to 48 total racks using the same subscription rates.
In a multi-AS underlay design
- A . All spine switches are in the same AS while each leaf (VSX pair if used) are in their own AS
- B . Every spine and every leaf is in their own AS
- C . All spine and leaf switches are in one AS and the border leaf is in separate AS
- D . Every spine is in their own AS while all leaf switches in one AS
Loopback addresses are very useful for troubleshooting and for device management.
What is true about the loopback interfaces?
- A . Not required for underlay connectivity using OSPF
- B . Should be avoided if NSX is used as an overlay
- C . Not required for EVPN VXLAN
- D . They need to be advertised for underlay connectivity when using OSPF
What is the transit VLAN that runs between VSX members?
- A . Must not be assigned IP addresses on any switch.
- B . It is used as a keepAlive mechanism
- C . It is a routed VLAN allowed in the ISL to ensure that the two switches within a VSX pair can learn routes from one another, in potential failover situations
- D . Must be assigned identical IP address on both of the switches
You are involved in a 2-Tier L2 Data Center Design with the following details:
• CX 8325 100G Core Switches
• CX 10000 48-P 25G Access Switches
• 100G SR4 Optical connections between Core and Access
In this design, both the Core Layer and Access Layer consist of pairs of switches configured in VSX for HA.
Core Switches = VSX Pairs of CX 8325 32-port 100G switches (B-F airflow) Each pair uses:
• 2 x 100G QSFP28 1M DACs for ISL
• 1 x 100G QSFP28 1M DAC for Keepalive
• 2 x 100G QSFP28 SR4 Optic to each access switch Each Core switch has 13 available 100G QSFP28 interfaces.
What is the maximum number of racks supported by this design?
- A . Solution can scale to 7 total racks using the same subscription rates.
- B . Solution can scale to 14 total racks using the same subscription rates.
- C . Solution can scale to 8 total racks using varying subscription rates.
- D . Solution can scale to 16 total racks using the same subscription rates.
In MMF OM3 fiber type and SFP28 LC SR transceiver option.
What is the maximum distance supported by this setup?
- A . Up to 50 meters
- B . Up to 70 meters
- C . Up to 500 meters
- D . Up to 700 meters
What can be used to encrypt data in flight between untrusted locations?
- A . OSPF authentication
- B . MACSec
- C . GRE tunnels
- D . MD5 encryption
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 service leaf 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 L2 edge switches, which are dedicated to connecting the spine and leaf topology to external networks
In one of the spine and leaf designs, VMware vSphere is used including VMware NSX. OSPF is used for routing protocol across the spine and leaf topology.
What do you need to consider in this design? (Select three)
- A . Adding an anycast loopback interface on each VSX pair
- B . Using a L2 MTU of 9198 on leaf-to-spine links
- C . Using an IP MTU of 9198 on leaf-to-spine links
- D . Enabling OSPF in passive interface mode on the NSX transport VLAN
