QUESTION 21
In the diagram below, an end-to-end transport tunnel needs to be established between PE1 and PE2 using MP-BGP. Which of the following items is NOT required?

MP-BGP address families label-ipv4 or label-ipv6 need to be supported on each of the edge routers.

Either RSVP, LDP, or segment routing tunnels need to be established between regions.

Either RSVP, LDP, or segment routing tunnels need to be established within each region.

Each PE router needs to advertise an IP address as a labeled BGP route to identify the tunnel endpoint.

QUESTION 22
What is the result of configuring the following policy statement as a BGP import policy on the Nokia 7750 SR?

All BGP routes are accepted.

All routes matching prefix lists “List-1” and “List-2” are rejected.

BGP routes matching prefix lists “List-1” or “List-2” are rejected.

BGP routes matching prefix lists “List-1” and “List-2” are rejected.

QUESTION 23
Which of the following statements about a distributed EVPN VPRN service is FALSE?

It acts as a router, carrying IP packets between customer sites.

It requires two types of interfaces, one towards customer sites and one towards the backhaul VPLS.

Its configured route target indicates to the PE router which of the received BGP route updates are relevant to this VPRN.

It relies on MP-BGP and on the EVPN address family to populate its routing table.

QUESTION 24
What type of information does a type-2 EVPN route update carry?

It carries an IP prefix and its associated mask.

It carries an IP address and requests the MAC address of the corresponding host.

It carries a host MAC address and optionally the associated IP address that belongs to the same host.

It carries a host MAC address and optionally the IP prefix of the subnet where the host is located.

QUESTION 25
Click the exhibit.

Assuming the network is IPv6 only, which of the following configurations on the Nokia
7750 SR router A can establish an IPv6 BGP session to router B?

Option A

Option B

Option C

Option D

QUESTION 26
Click the exhibit.

An update travels from AS 137000 to AS 135000, traversing both 32-bit and 16-bit AS Paths.
What AS Path is seen by AS 200?

140000 137000

137000 140000

23456 23456

200 140000 137000

QUESTION 27
Which of the following statements about the MED BGP path attribute is FALSE?

The MED BGP path attribute is transitive.

The MED BGP path attribute is optional.

Routes having lower values in their MED BGP path attribute are preferred.

The MED BGP path attribute’s value is set by a router at the edge of an AS.

QUESTION 28
A traditional (non EVPN) VPRN service is configured using MP-BGP and LDP transport tunnels. Which of the following statements about the VPN service label is TRUE?

The service label is advertised using LDP.

The service label is prepended to the customer IPv4 prefixes.

The service label must be manually configured for the VPRN on each PE router.

The service label is carried in an MP-BGP VPN-IPv4 route update.

QUESTION 29
Which of the following statements about router reflectors is FALSE?

A full iBGP mesh is required among route reflectors.

A route reflector can have both iBGP and eBGP clients.

A router reflector disables the iBGP split-horizon rule for its clients.

Route reflectors are used to reduce the number of iBGP sessions required in an AS.

QUESTION 30
The diagram shows EVPN services and their associated route-target (RT) values. For the distributed VPRN service in the diagram, what will be the route-target value included in the EVPN routes exchanged between routers PE1 and PE2 to populate the VPRN’s route table?

65200:100

65200:200

65200:300

65200:400

QUESTION 31
Which of the following statements about Route Distinguishers (RD) is FALSE?

An RD is prepended to an IPv4 prefix to form a VPN-IPv4 prefix.

An RD is used to indicate the VPRN service to which a route update is relevant.

A unique RD value is assigned to each VPRN service.

An RD is a 64-bit value.

QUESTION 32
Which of the following statements about BGP is FALSE?

Peers need to be IP reachable to establish a BGP session.

Route reflectors can reduce the number of iBGP sessions required.

iBGP peers have to be adjacent to each other.

The multihop parameter needs to be configured when eBGP peers are not adjacent to each other.

QUESTION 33
Which of the following statements about IPv6 Link-Local addresses is FALSE?

They are assigned to every physical interface running IPv6.

They are only valid for communication within the same broadcast domain.

They all have the same 64-bit subnet prefix.

They have an interface ID derived by default from the interface’s IPv4 address.

QUESTION 34
The configuration of an Nokia 7750 SR is given below. Router Rl has established BGP sessions with routers R2 and R3. Which of the following is TRUE?

Router R1forms an iBGP session with router R2, and an eBGP session with router R3.

Router R1forms iBGP sessions with routers R2 and R3.

Router R1forms eBGP sessions with routers R2 and R3.

The types of BGP sessions with routers R2 and R3 cannot be determined.

QUESTION 35

Hello

Update

Open

Keep-Alive

QUESTION 36
Which of the following regarding route reflectors is TRUE?

Only the route reflector is configured with a cluster id.

There can only be one route reflector in a cluster.

Clients should have iBGP sessions with each other to maintain the mesh.

There can only be one level of route reflectors in the topology.

QUESTION 37
A BGP session is stuck in the “Connect” state. Which of the following is the most likely reason?
