QUESTION 14
You have configured MSTP in your Layer 2 network.
You are having problems with it establishing correctly.
Referring to the exhibit, what is causing the problem?

You must assign a context ID number other than zero

The MSTI-to-VLAN mapping does not match

The region name is not correct

The revision number is the same on both devices

QUESTION 15
You are deploying IP phones to a customer site. The IP phones will be installed to share a common access port with the user’s desktop computer. You are required to provide a mechanism to place user data traffic and voice traffic in different VLANs for class-service application How would you implement this solution?

Configure flexible VLAN tagging on the user ports with the data and voice VLANs as members

Apply a multifield classifier on the access ports that assigns voice packets to the assured forwarding class, based on the IP phone manufacturer’s MAC QUI

Configure the IP phones to label voice traffic with the DSCP of code point and apply a BA classifier to the access ports to classify voce traffic

Configure VLAN tagging on the IP phones and use the voice VLAN feature on the access ports to assign lagged frames to the voice VLAN and untagged frames to a data VLAN

QUESTION 16
Referring to the exhibit, which two statements are correct? (Choose two.)

The maximum wattage that this switch can allocate to attached Ethernet devices is 100 watts.

If the total power consumption exceeds 90 watts, the ge-0/0/11 interface will continue to receive power.

PoE is not enabled on the ge-0/0/0 interface.

The ge-0/0/10 interface supports PoE+.

QUESTION 17
When redistributing IGP routes into BGP. what information .s used by default on Junos platforms to determine the BGP route’s MED attribute value?

routing information base

the IGP route preference

the IGP Metric

route protocol source

QUESTION 18
Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)

VLAN to instance mapping

revision level

configuration name

bridge priority

region name

When enabling MSTP, you define one or more MSTP regions. An MSTP region defines a logical domain where multiple spanning-tree instances (MSTIs) can be administered independently of MSTIs in other regions, setting the boundary for bridge protocol data units (BPDUs) sent by one MSTI. An MSTP region is a group of switches that is defined by three parameters:
Region name-User-defined alphanumeric name for the region.
Revision level-User-defined value that identifies the region.
Mapping table-Numerical digest of VLAN-to-instance mappings.

QUESTION 19
A customer on MSTI-2 was isolated due to a physical link outage on Switch 5’s ge-0/0/32 interface.

Referring to the exhibit, which corrective action would solve this problem?

replace the link between Switch 5 and 6 with a 10 Gbps link

Implement the CIST on all switches.

Move the root bridge for MSTI-2 to Switch 6.

Add MSTI-2 to all interfaces on Switch 5.

QUESTION 20
You are asked to establish full connectivity between all devices in the BGP network.
Referring to the exhibit, which two configuration changes will allow BGP route advertisements? (Choose two.)

On R2, include the loops 2 statement at the [edit protocols bgp family inet unicast] hierarchy.

On R1 and R3, include the loops 2 statement at the [edit protocols bgp family inet unicast] hierarchy.

On R1 and R3, include the advertise-peer-as statement at the [edit protocols bgp group external] hierarchy.

On R2, include the advertise-peer-as statement at the [edit protocols bgp group external] hierarchy.

QUESTION 21
Which three databases are used by the Dijkstra algorithm? (Choose three.)

Tree database

Link State Database

Candidate database

MAC database

Configuration database

QUESTION 22
You are asked to establish interface level authentication for users connecting to your network.
You must ensure that only corporate devices, identified by MAC addresses, are allowed to connect and authenticate. Authentication must be handled by a centralized server to increase scalability. Which authentication method would satisfy this requirement?

MAC RADIUS

captive portal

802.1X with single-secure supplicant mode

802.1X with multiple supplicant mode

QUESTION 23
You will to route Layer 3 PVLAN traffic within the secondary VLAN.
What is required to accomplish this task?

a community VIAN

an IRB

an FBF policy

an isolated VLAN

QUESTION 24
You are configuring MSTP to prevent loops in your Layer 2 network. After applying the configuration, you notice that MSTO is not working correctly.

Referring to the exhibit, what is causing the problem?

Too many VLANs have been defined.

Context identifier must be specified.

MSTI-to-VLAN mappings must be the same.

Incorrect revision number is used.

QUESTION 25
You are implementing 802.1x access control in your network of EX Series switches. You have some older client devices connecting to your network which do not support 802.1x.
Which statement is true regarding the older devices?

By default, the supplicant will send EAP messages and keep the port in an unauthorized state.

By default, the authenticator will send EAP messages and keep the port in an unauthorized state.

By default, the supplicant will send EAP messages until it reaches a predefined limit, after which it begins to forward traffic.

By default, the authenticator will send EAP messages until it reaches a predefined, after which it begins to forward traffic.

QUESTION 26
You have configured 802.1X single supplicant mode on the access switch. The VoIP phone does not support 802.1X authentication.

Referring to the exhibit, which statement is true?

MAC bypass must be configured for the VoIP phone for this solution to work.

Authentication must be changed to multiple supplicant mode for this solution to work.

The VoIP phone will be able to communicate over the network after the workstation authenticates.

The VoIP phone will not be able to communicate over the network.

QUESTION 27
You want to implement an RP in your PIM sparse mode environment, you are considering the advantages and disadvantages of the various RP election methods.
In this scenario, which three implementation guidelines are correct? (Choose three.)

The auto-RP method requires using two PIM dense mode groups from the 323/8 range.

The auto-RP method includes the ability to maintain a backup RP.

With the bootstrap method, the primary criterion for electing a BSR is priority value.
