Questions # 1:

What is a design consideration for using IBGP for the underlay in a Clos data center fabric?

Options:

A full mesh of IBGP neighbors will be required.

BGP ADD-PATH must be enabled for multipath to work on leafs.

An IGP will always be required for learning loopback addresses.

A 5-stage Clos topology will not work with IBGP underlay.

Answer

Explanation

In a Clos data center fabric using IBGP as the underlay, BGP ADD-PATH must be enabled to allow multiple equal-cost paths to be advertised and installed on the leaf switches. This supports ECMP (Equal-Cost Multi-Path) routing, which is essential for optimal traffic distribution in the fabric.

Questions # 2:

Which two switches should you recommend as leaf nodes for a small data center where cost is a factor? (Choose two.)

Options:

EX4300

QFX5700

EX4400

QFX5130

Answer

A, C

Explanation

For a cost-sensitive small data center, the EX4300 and EX4400 switches are suitable leaf node options. They offer sufficient port density and features like Virtual Chassis or EVPN-VXLAN (EX4400) at a lower cost compared to high-end QFX models.

Questions # 3:

You are considering changing an IBGP-based IP fabric design to one that is EBGP-based.

In this scenario, which two statements are correct about an EBGP-based design? (Choose two.)

Options:

Route reflection is not required.

An IGP is not required.

AS numbers are not required.

Confederations may be used.

Answer

A, B

Explanation

In an EBGP-based IP fabric, each router is in a separate AS, so route reflection is unnecessary - each peer communicates directly. Also, since EBGP peers can form adjacencies using directly connected interfaces, an IGP is not required for underlay routing, simplifying the control plane.

Questions # 4:

Which two technologies would be used to encapsulate frames to provide Layer 2 reachability across an IP fabric data center? (Choose two.)

Options:

MACsec

IPsec

MPLS

VXLAN

Answer

C, D

Explanation

VXLAN and MPLS are commonly used to encapsulate frames and provide Layer 2 reachability across an IP fabric. VXLAN enables L2 overlays over L3 infrastructure, while MPLS can also be used in L2VPN services to extend L2 connectivity across IP/MPLS networks.

Questions # 5:

Click the Exhibit button.

Question # 5

Which WAN function is shown in the exhibit?

Options:

WAN aggregation

Data Center Interconnect

Internet edge

private WAN

Answer

Explanation

The diagram shows an enterprise WAN connected to two different ISPs through edge routers, with security elements in place. This configuration is characteristic of an Internet edge design, where the enterprise network interfaces with external service providers, providing redundancy and secure access to the internet.

Questions # 6:

You are asked to design a branch WAN. The branch sites have limited bandwidth and it is imperative to limit overhead.

Which technology will satisfy the requirements?

Options:

Secure Vector Routing

Generic Routing Encapsulation

IPsec

EVPN-VXLAN

Answer

Explanation

Secure Vector Routing (SVR) is specifically designed for SD-WAN environments with limited bandwidth, as it offers encrypted and policy-based routing with minimal overhead compared to protocols like IPsec or GRE. This makes it ideal for bandwidth-constrained branch sites.

Questions # 7:

You need to deploy a content filtering solution to block access to some Web sites.

In this scenario, which solution would you implement?

Options:

IDP

UTM

firewall rules

Juniper ATP On-Premises

Answer

Explanation

UTM (Unified Threat Management) includes content filtering capabilities, allowing you to block access to specific websites or categories. It is the most appropriate solution for implementing web filtering policies in a network security deployment.

Questions # 8:

Which two statements are correct about greenfield and brownfield deployments? (Choose two.)

Options:

A brownfield deployment has no network environment.

A greenfield deployment has no network environment.

A greenfield deployment has a network environment and must be upgraded.

A brownfield deployment has a network environment and must be upgraded.

Answer

B, D

Explanation

A greenfield deployment starts from scratch, with no existing infrastructure, allowing for full design freedom. A brownfield deployment involves working within an existing network environment that typically requires integration or upgrades.

Questions # 9:

Which two products comprise Juniper’s SASE solution? (Choose two.)

Options:

Juniper

Juniper Secure Edge

Paragon Active Assurance

Mist Al-Driven SD-WAN

Answer

B, D

Explanation

Juniper’s SASE (Secure Access Service Edge) solution combines Juniper Secure Edge, which delivers cloud-based security services, and Mist AI-Driven SD-WAN, which provides secure, intelligent WAN connectivity. Together, they support secure, seamless access across distributed environments.

Questions # 10:

Which two statements about network management are correct? (Choose two.)

Options:

Fault management can discover problems before they cause downtime.

Authorization validates that a user is who they claim to be.

Measurement of network performance, errors, and security allows administrators to make informed decisions.

Network management is added after the network is built and network designers do not need to consider it.

Answer

A, C

Explanation

Fault management helps detect and address potential issues before downtime occurs, while measuring network performance, errors, and security metrics enables administrators to make data-driven decisions for maintaining and optimizing the network.
