 Question: 1
Click the Exhibit button.

Given the information shown in the exhibit, what was used to
determine mastership?

A. member uptime

B. manuallyassigned role

C. highest serial numbe

D. manually assigned priority

Answer: A

Explanation:
When a Virtual Chassis configuration boots, the Juniper Networks
Junos operating system (Junos OS) on the switches automatically
runs a master election algorithm to determine which member
switch assumes the role of master.

The algorithm proceeds from the top condition downward until the
stated condition is satisfied:

Question: 2
Which two statements are true about OSPF not-so-stubby areas?
(Choose two.)

A. The ASBR originates Type 7 LSAafor redistributed external
routes.

B. Type 5 LSAs are translated by the ASBR into Type 7 LSAs.

C. The ASBR originates Type 5 LSAs for redistributed external
routes.

D. Type 7 LSAs are translated by the ABR into Type 5 LSAs.

Answer: A,D

Explanation:
Redistribution intoan NSSA area creates a special type of
link-state advertisement (LSA) known as type 7, which can only
exist in an NSSA area. An NSSA autonomous system boundary router
(ASBR) generates this LSA and an NSSA area border router (ABR)
translates it into a type5 LSA, which gets propagated into the
OSPF domain.

Question: 3
Click the Exhibit button.

Referring to the exhibit, which statement is true?

A. R3 has the complete OSPF database.

B. R3 and R4 have an adjacency state ofFull.

C. R4 is elected as the DR.

D. R1 and R2 are elected as DROTHERs.

Answer: A,C

Explanation:
C: In LANs, the election of the designated router takes place
when the OSPF network is initially established. When the first
OSPF links are active, the routing device with the highest
router identifier (defined by the router-id configuration value,
which is typically the IP address of the routing device, or the
loopback address) is elected the designated router.

Question: 4
An EBGP session sources its TCP connection from which IP
address?

A. The IP address of the primary address assigned to the
loopback interface.

B. The IP address assigned as the router ID.

C. The IP address of the preferred address assigned to the
loopback interface.

D. The IP address of the interface that connects the two BGP
speakers.

Answer: D

Explanation:
The BGP session between two BGP peers is said to be an external
BGP (eBGP) session if the BGP peers are in different autonomous
systems (AS) . A BGP session between two BGP peers is said to be
an internal BGP (iBGP) session if the BGP peers are in the same
autonomous systems.

By default, the peer relationship is established using the IP
address of the interface closest to the peer router.

Question: 5
You notice that there are currently two MAC addresses associated
with a single access port in the bridge table on one of your EX
Series switches.

What are two explanations for this behavior? (Choose two.)

A. The access port connects to an IP phone which connects to a
host device.

B. The native VLAN feature has been associatedwith the access
port.

C. Themac-move-limitfeature has been disabled on the access
port.

D. The access port connects to multiple hosts through a rogue
device.

Answer: B,D

Explanation:
MAC move limiting detects MAC movement and MAC spoofing on
access interfaces. You enable this feature on VLANs.
