QUESTION 176

Select the 3 best answers describing operation and configuration of Frame-Relay Inverse ARP.

 

A.

Dynamic address mapping uses Frame Relay Inverse ARP to request the next-hop protocol address for a specific connection on its known DLCI.

B.

Responses to Inverse ARP requests are entered in an address-to-DLCI mapping table on the router or access server whichis used to supply the next-hop protoco address or the DLCI for outgoing traffic.

C.

Inverse ARP is enabled by default for all protocols enabled on the physical interface.

D.

Inverse ARP is configured using the following command under the Interfaceconfiguration ‘frame-relay mapdlci (dlci number) protocol protocol-address’.

E.

Inverse ARP in Frame-Relay is synonymous of ARP in Ethernet.

QUESTION 179

Which two things are correct about QinQ technology? (Choose two.)

 

A.

The Outer.1Q tag represents customer VLAN ID and inner.1Q tag represents Service Provider VLAN (PVLAN)

B.

It is an effective way to achieve VLAN transparency between Provider and enterprise customer by tunneling one ser of VLAN tags inside a second VLAN tag

C.

The Outer.1Q tag represents Service Provider VLAN (PVLAN) and inner.1Q tag represents customer VLAN

D.

QinQ is a way to hide native VLAN which can conflict with Provider native VLAN

 

Correct Answer: BC

Explanation:

IEEE 802.1ad[note 1] is an Ethernet networking standard informally known as IEEE 802.1QinQ[by whom?] and is an amendment to IEEE standard IEEE 802.1Q-1998. The technique is also known as provider bridging, Stacked VLANs, or simply QinQ or Q-in-Q. “Q-in-Q” can for supported devices apply to C-tag stackingon Ctag (Ethernet Type = 0x8100) but this has limited application in the modern methodology of network routing.

 

The original 802.1Q specification allows a single Virtual Local Area Network (VLAN) header to be inserted into an Ethernet frame. QinQ allows multiple VLAN headers to be inserted into a single frame, an essential capability for implementing Metro Ethernet network topologies. Just as QinQ extends 802.1Q, QinQ itself is extended by other Metro Ethernet protocols.[specify]

In a multiple VLAN headercontext, out of convenience the term “VLAN tag” or just “tag” for short is often used in place of “802.1Q VLAN header”. QinQ allows multiple VLAN tags in an Ethernet frame; together these tags constitute a tag stack. When used in the context of an Ethernetframe, a QinQ frame is a frame that has 2 VLAN 802.1Q headers (double-tagged).

There is a mild confusion regarding the naming because the 802.1ad standard was grown out of the 802.1QinQ[citation needed] protocol (which was developed based the trademarkedmethod 802.1Q, with capital “Q” as a distinction instead of the 802.1q as the standardised protocol) which originally used 0x8100 as ethernet type instead of 0x88a8. While the network industry usually mix the naming, the proper, standardized name is 802.1ad which sometimes gets appended by the other alternative names mentioned above; the plain “802.1QinQ”[citation needed] name usually refers to the old standard which is now[when?] considered obsolete.

 

 

 

 

QUESTION 180

In the context of GMPLS, LMP stands for:

 

A.

Load Management Protocol

B.

Label Management Protocol

C.

Loop Management Protocol

D.

Link Management Protocol

 

Correct Answer: D

Explanation:

The Generalized Multi-Protocol Label Switching (GMPLS)[1] is a protocol suite extending MPLS to manage further classes of interfaces and switching technologies other than packet interfaces and switching, such as time division multiplex, layer-2 switch, wavelength switch and fiber-switch.

GMPLS is composed of three main protocols:

Resource Reservation Protocol with TrafficEngineering extensions (RSVP-TE) signaling protocol.[5][6]Open Shortest Path First with Traffic Engineering extensions (OSPF-TE) routing protocol.[7][8] Link Management Protocol (LMP).[9]
