This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with “X” fails?

A.

Ethernet linear protection switching

B.

PVRST

C.

MST

D.

Ethernet ring protection switching

A large ISP is analysing which IGP meets these following requirements

ï‚· Network must be resilient against unstable MTU in one side of newly released transmission pieces of equipment

ï‚· Network must support MPLS traffic engineering solution for future use

Which IGP must be selected and why?

A.

ISIS : in case MTU changes your TE tunnels keep the LSP stable

B.

OSPF: adjacency remains up even if MTU changes

C.

OSPF: in case MTU changes your TE tunnels keep the LSP stable

D.

ISIS: adjacency remains up even if MTU changes

Which option describes the fundamental design differences between an IP-based network design and a SAN-based?

A.

An IP-based design has redundant connectivity in the fabric and high amounts of east-west traffic, whereas a SAN-based design uses redundancy from a dual-attached host, which uses separate fabrics and has very little east-west traffic

B.

An IP-based design has redundancy from the host and high amounts of east-west traffic, whereas a SAN-based design uses redundancy in the fabric and very little east-west traffic

C.

An IP-based design has redundant connectivity in the fabric and high amounts of east-west traffic, whereas a SAN-based design uses zoning based redundancy which uses separate fabrics and has very little east-west traffic

D.

An IP-based design has redundant connectivity in the fabric and very little east-west traffic, whereas a SAN-based design uses redundancy in the host, which uses separate fabrics and has high amounts of east-west traffic

A network has several routers running IS-IS L1L2 mode on the same Ethernet segment. Which action reduces to a minimum the number of IS-IS adjacencies in this segment?

A.

Define only the router on the segment to be DIS

B.

Change all routers connected to this segment to a single-level area

C.

Make the interface priority on the backup DIS lower than the primary DIS

D.

Change half the routers to be L1-only and other half to be L2-only on this segment

Which effect of designing a Layer 2 network using the PortFast fast feature with PVST+ is true?

A.

It shuts down the port when receiving the superior BPDU

B.

It accelerates the network convergence on the trunk uplinks

C.

In combination with BPDU filtering, it causes the switch port to stay in the forwarding state

D.

It moves the switch port directly to the forwarding state

Which three processes are part of the ITILv3 Service Operation? (Choose three)

A.

Release and deployment management

B.

Problem management

C.

Incident management

D.

Event management

E.

Service-level management

F.

Change management

Which three different behaviors must a network designer expect when bidirectional PIM is used instead of PIM Sparse Mode? (Choose three)

A.

The source IP addresses from the multicast senders cannot be seen in the multicast routing table

B.

The RPF check does not prevent routing loops when bidirectional PIM is used

C.

Many possible rendezvous point can be used for bidirectional PIM as compared to PIM Sparse Mode

D.

PIMv2 BSR is not supported with bidirectional PIM

E.

The join messages to join a bidirectional PIM multicast group are different compared to PIM-SM

F.

No rendezvous point is required when bidirectional PIM is used

G.

Auto-RP is not supported with bidirectional PIM

Which option is a critical mechanism to optimize convergence speed when using MPLS FRR?

A.

IGP timers

B.

Bandwidth reservation

C.

Shared risk link groups

D.

Down detection

Which markup language is used to format Ansible's playbook?

A.

ADML

B.

YAML

C.

HTML

D.

XML

E.

NAML

Which option describes a design benefit of root guard?

A.

It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST+ and MST.

B.

It prevents switch loops by detecting on one-way communications on the physical port.

C.

It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.

D.

It makes the port go immediately into the forwarding state after being connected.

E.

It prevents switched traffic from traversing suboptimal paths on the network.

F.

It does not generate a spanning-tree topology change upon connecting and disconnecting a station on a port.
