Juniper JNCDS-DC JN0-1301 Questions & Answers

  • Question 51:

    Your data center uses a Virtual Chassis Fabric. The ToR switches have 48 ports and each rack supports 20 servers. Each server has two ports that are configured as a LAG.

    You need to implement link level redundancy but you cannot use two ports on the same device for this redundancy.

    Which type of connection should you use to complete this task?

    A. MC-LAG

    B. RTG

    C. LAG

    D. ESI

  • Question 52:

    What are two requirements for a VXLAN tunnel endpoint (VTEP)? (Choose two.)

    A. TCP session tracking

    B. MAC address learning

    C. IGMP filtering

    D. IP address learning of interested VTEPs

  • Question 53:

    You are designing a Layer 2 fabric implementation for a small data center and have chosen to implement a Virtual Chassis Fabric. You must accommodate two racks of servers with 1 Gbps connectivity, 10 racks of servers with 10 Gbps connectivity, and maintain a single management interface.

    Which device would satisfy the requirements in this implementation?

    A. QFX5110

    B. QFX10002

    C. EX4600

    D. EX4300

  • Question 54:

    Clos architectures are based on which network topology?

    A. ring

    B. VLANs

    C. hybrid

    D. spine and leaf

  • Question 55:

    What are two methods used to protect the data center perimeter? (Choose two.)

    A. session authentication

    B. DDoS protection

    C. asset classification

    D. network subnetting

  • Question 56:

    Which two statements are true about IP fabrics? (Choose two.)

    A. IP-based applications do not require an overlay network to maintain connectivity.

    B. Applications that require security needs an overlay to provide the security.

    C. Applications that require Layer 2 adjacencies require an overlay network to maintain connectivity.

    D. IP fabrics can natively support both Layer 2 and Layer 3 applications.

  • Question 57:

    What are two Layer 2 traffic tunneling schemes that are supported in a Juniper Networks IP fabric? (Choose two.)

    A. EVPN

    B. MPLSoGRE

    C. GENEVE

    D. VXLAN

  • Question 58:

    A customer has selected QFX5110 switches. The initial installation will contain two switches located in

    racks about two meters apart.

    What is the most cost-effective way to interconnect these switches?

    A. Use SMF between the racks and interconnect the switches with LX4 transceivers.

    B. Use a Virtual Chassis cable between the VCP cards.

    C. Use MMF between the racks and interconnect the switches with SR4 transceivers.

    D. Use a three-meter passive DAC cable between the racks and interconnect the switches with it.

  • Question 59:

    You want to provide Layer 2 connectivity to a backup data center or to a disaster recovery site. What would you use to accomplish this task?

    A. Data Center Interconnect

    B. network redundancy

    C. SDN

    D. SAN protocols

  • Question 60:

    You are creating a design proposal and deciding whether to use 10 GbE copper or 10GbE fiber cabling to connect your ToR switches to the servers.

    Which statement is correct regarding this scenario?

    A. Fiber has a lower power consumption on a per-port basis.

    B. Copper cabling requires special transceivers for different speeds.

    C. Fiber is much cheaper to purchase but has a higher long-term cost.

    D. Copper will allow you to reach the greatest distance between devices.
