質問 # 20
Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.
How would you accomplish this task?

A. Configure VSTP on interface ge-0/0/1 to assign the VLANs.
B. Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.
C. Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.
D. Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.

正解：B

解説：
EX switches has VLAN action on ingress interfaces to forward traffic to specific VLAN.

internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the Multicast Group Membership Discovery (MGMD) protocols

質問 # 23
Referring to the exhibit, which two statements are correct? (Choose two.)

A. The ge-0/0/10 interface supports PoE+.
B. PoE is not enabled on the ge-0/0/0 interface.
C. If the total power consumption exceeds 90 watts, the ge-0/0/11 interface will continue to receive power.
D. The maximum wattage that this switch can allocate to attached Ethernet devices is 100 watts.

正解：A、D

解説：
POE is enabled in the interface ge-0/0/0 but nothing is connected to it. switch is in AT mode (poe+) and interface ge-0/0/11 supports poe+ judging by maximun wattage.

質問 # 24

C. On R2, include the advertise-peer-as statement at the [edit protocols bgp group external] hierarchy.
D. On R1 and R3, include the loops 2 statement at the [edit protocols bgp family inet unicast] hierarchy.

正解：C、D

質問 # 25
Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.
Which two statements would accomplish this task? (Choose two.)

A. Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.
B. Configure the multipath option at the [edit protocols bgp group] hierarchy.
C. Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.
D. Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding- table] hierarchy.

正解：A、B

質問 # 26
What are two supported PoE management modes? (Choose two.)

A. standalone
B. mixed
C. class
D. static

正解：C、D

質問 # 27
You must provide network connectivity to hosts that fail authentication.
In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

A. Configure a secondary IP address on the port for unauthenticated hosts.
B. Use the server-reject-vlan command to specify a guest VLAN.
C. Configure the native-vlan-id parameter on the port.
D. Configure the port as a spanning tree edge port.

正解：B

解説：
For a device configured for 802.1X authentication, specify that when the device receives an Extensible Authentication Protocol Over LAN (EAPoL) Access-Reject message during the authentication process between the device and the RADIUS authentication server, supplicants attempting to access the LAN are granted access and moved to a specific bridge domain or VLAN. Any bridge domain, VLAN name or VLAN ID sent by a RADIUS server as part of the EAPoL Access-Reject message is ignored.

質問 # 28
You are configuring MVRP for automatic VLAN registration. Which two statements are true?

質問 # 32
A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.
Which two statements are correct in this scenario? (Choose two.)

A. Both the next hops will be used to forward traffic to R2.
B. The TTL value of 1 is set to limit the scope of the EBGP session.
C. A routing policy will be required to forward traffic to both next hops.
D. The ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.

正解：B、C

解説：
B - Because only one next hop in forwarding table.
C- Becuse TTL=1 limiting bgp connection to be established only over loopbacks interface.
https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic-map/multihop- sessions.html Use the multihop statement to alter the default use of the neighbor's physical address. In addition, you can also specify a time-to-live (TTL) value in the BGP packets to control how far they propagate. We use a TTL value of 1 to ensure that the session cannot be established across any other backdoor links in the network.
